00:00:23.802 --> 00:00:24.811
Hello

2
00:00:24.811 --> 00:00:28.235
Today, let's take some time

3
00:00:28.235 --> 00:00:31.320
to analyze new technologies in more detail

4
00:00:32.340 --> 00:00:36.967
Today, we will utilize various sensors and

5
00:00:36.967 --> 00:00:41.099
how they can be used to interact with users

6
00:00:41.099 --> 00:00:46.350
Next, we'll explore the importance and potential applications of XR technology

7
00:00:46.350 --> 00:00:49.564
So, based on these aspects

8
00:00:49.564 --> 00:00:53.730
we aim to utilize new technologies in immersive content

9
00:00:53.730 --> 00:00:58.091
and to discuss what kinds of content

10
00:00:58.091 --> 00:01:00.273
can emerge from these technologies

11
00:01:00.955 --> 00:01:04.737
Definitions and Applications of XR

12
00:01:04.737 --> 00:01:10.235
First, let's discuss the definition and applications of XR

13
00:01:10.235 --> 00:01:16.082
I assume the definitions of XR, VR, AR, and MR

14
00:01:16.082 --> 00:01:17.339
have been covered in many lectures

15
00:01:17.820 --> 00:01:23.228
However, I'll try to explain these concepts

16
00:01:23.228 --> 00:01:25.451
focusing less on theoretical and foundational aspects

17
00:01:25.451 --> 00:01:27.814
in a more simple way

18
00:01:28.220 --> 00:01:31.791
AR is simply based on smartphones

19
00:01:32.919 --> 00:01:36.922
You can think of it as viewing through the camera lens

20
00:01:36.922 --> 00:01:39.379
Perhaps it's easier to think of it that way

21
00:01:39.379 --> 00:01:40.850
Then, what's VR?

22
00:01:40.850 --> 00:01:47.562
VR is based on HMD, which stands for Head-Mounted Display

23
00:01:47.562 --> 00:01:51.497
it's entering a virtual world to enjoy content

24
00:01:51.497 --> 00:01:54.620
VR can be defined as immersing oneself in a virtual environment to experience content

25
00:01:54.620 --> 00:01:56.875
Then, what's MR?

26
00:01:56.875 --> 00:02:02.557
MR can be defined as being based on HMD

27
00:02:02.557 --> 00:02:07.518
But incorporating lens-based technology to simultaneously show the real world

28
00:02:07.518 --> 00:02:10.779
allowing for augmented experiences

29
00:02:10.779 --> 00:02:16.501
Actually, the definitions I just provided for AR, VR, and MR were

30
00:02:16.501 --> 00:02:20.660
to help everyone understand

31
00:02:20.660 --> 00:02:24.206
It might be helpful to blend those examples a bit

32
00:02:24.206 --> 00:02:26.979
for easier understanding

33
00:02:26.979 --> 00:02:29.894
When I approach technology

34
00:02:29.894 --> 00:02:35.779
I often see technology based on content from movies

35
00:02:35.779 --> 00:02:41.082
In fact, if you enjoy sci-fi movies, you'll see all sorts of futuristic technologies in them

36
00:02:41.964 --> 00:02:46.746
So, practicing matching terms with scenes

37
00:02:46.746 --> 00:02:48.763
from such movies might make it easier

38
00:02:48.763 --> 00:02:54.060
for you to encounter new technologies

39
00:02:54.060 --> 00:02:58.699
Thus, we've concluded with the definitions of AR, VR, and MR, returning to the basics

40
00:02:58.699 --> 00:03:00.660
What's the definition of XR?

41
00:03:00.660 --> 00:03:06.651
XR is a definition that combines all definitions of AR, VR, and MR

42
00:03:07.216 --> 00:03:14.177
So, some people actually refer to AR as XR as well

43
00:03:14.177 --> 00:03:17.330
or VR as XR

44
00:03:17.330 --> 00:03:20.264
or even MR as XR

45
00:03:20.264 --> 00:03:22.025
However, it's not an incorrect statement

46
00:03:22.025 --> 00:03:25.689
But if you see XR as an overarching concept

47
00:03:25.689 --> 00:03:28.109
it could be seen as a somewhat incorrect statement in that context

48
00:03:28.109 --> 00:03:31.754
So, going forward, the definition of XR would be

49
00:03:31.754 --> 00:03:35.609
I see it as spatial-based or spatial-content

50
00:03:35.609 --> 00:03:38.510
which is likely to expand

51
00:03:38.510 --> 00:03:42.548
That's not to say that AR, VR, and MR aren't part of XR

52
00:03:42.548 --> 00:03:46.339
But it's important to clearly distinguish the differences between them

53
00:03:46.339 --> 00:03:51.107
Perhaps we could define AR, VR, MR and XR

54
00:03:51.107 --> 00:03:53.168
in terms of their potential for expansion

55
00:03:53.168 --> 00:03:59.460
and extension into these areas

56
00:03:59.460 --> 00:04:03.560
Then, if I were to give a simple definition of XR

57
00:04:03.560 --> 00:04:07.681
let's delve a bit deeper into the definition of AR this time

58
00:04:07.681 --> 00:04:10.268
AR stands for Augmented Reality, which means augmenting the real world with digital elements

59
00:04:11.070 --> 00:04:16.225
Augmented Reality, it's on top of the real world, in physical space

60
00:04:16.225 --> 00:04:20.133
It combines images or videos existing in real space with computer-generated graphics

61
00:04:20.707 --> 00:04:24.591
Therefore, it synthesizes images, whether they exist or not, into the real world

62
00:04:24.591 --> 00:04:27.881
It's a technology that creates virtual spaces within the real world

63
00:04:27.881 --> 00:04:30.555
Where? Where do they create it?

64
00:04:30.555 --> 00:04:33.176
Yes, it's created within a monitor

65
00:04:33.889 --> 00:04:36.524
This kind of augmented reality technology

66
00:04:36.524 --> 00:04:39.602
immerses users in virtual reality

67
00:04:39.602 --> 00:04:43.179
enabling real-time interactions that you can't see in the actual environment

68
00:04:43.179 --> 00:04:46.179
That's how it's defined in the dictionary

69
00:04:46.179 --> 00:04:52.120
Actually, this immersion is incredibly present in both VR and AR

70
00:04:52.120 --> 00:04:54.299
It seems to be present in MR and XR as well

71
00:04:54.299 --> 00:04:58.512
But the idea of immersion seems to involve a similar format to the real environment

72
00:04:58.512 --> 00:05:01.420
It seems to involve implementing that concept

73
00:05:01.420 --> 00:05:05.851
It relates to various industries such as broadcasting, video, and healthcare

74
00:05:05.851 --> 00:05:08.489
It's being applied in various areas

75
00:05:08.489 --> 00:05:12.204
However, AR is one of the most representative

76
00:05:12.204 --> 00:05:14.722
If we're talking about Pokemon GO

77
00:05:14.722 --> 00:05:18.961
the second most prominent thing we encountered after COVID-19

78
00:05:18.961 --> 00:05:21.009
could be considered QR codes

79
00:05:21.009 --> 00:05:22.972
I actually thought QR codes were going to disappear

80
00:05:23.477 --> 00:05:26.834
I find it as ugly and inconvenient

81
00:05:26.834 --> 00:05:30.114
In fact, after COVID-10, there's been a significant increase in the use of QR codes

82
00:05:30.114 --> 00:05:33.500
which have become highly activated

83
00:05:33.500 --> 00:05:39.583
When you go to places like restaurants, you often see keyboards, tablets, or similar devices for ordering, right?

84
00:05:39.583 --> 00:05:42.012
In the future, these kinds of processes will likely

85
00:05:42.012 --> 00:05:44.388
be mostly done through QR codes

86
00:05:44.388 --> 00:05:47.213
And these QR codes

87
00:05:47.213 --> 00:05:49.806
come in a wide variety

88
00:05:49.806 --> 00:05:53.138
serving as a means to promote oneself and express various aspects

89
00:05:53.138 --> 00:05:54.966
Next up is virtual reality

90
00:05:54.966 --> 00:05:58.230
Virtual reality is a completely imagined space

91
00:05:58.230 --> 00:06:00.398
It's a space that doesn't exist in reality

92
00:06:00.398 --> 00:06:05.767
That's why it requires special devices

93
00:06:05.767 --> 00:06:08.829
It's represented by devices like HMDs

94
00:06:08.829 --> 00:06:11.925
Through head-mounted displays

95
00:06:11.925 --> 00:06:16.189
they allow users to access virtual worlds from the real world

96
00:06:16.189 --> 00:06:19.362
and transform the real-world experience

97
00:06:19.362 --> 00:06:22.220
 into accessing an artificial environment

98
00:06:22.220 --> 00:06:29.297
In fact, virtual reality can be composed of real places or videos

99
00:06:29.297 --> 00:06:33.859
or it could be 100% computer-generated CG environments

100
00:06:33.859 --> 00:06:37.694
Real environments can be created using 360-degree cameras

101
00:06:37.694 --> 00:06:42.420
and those cameras can produce videos of actual locations

102
00:06:42.420 --> 00:06:44.737
By creating videos of these environments

103
00:06:44.737 --> 00:06:48.500
we try to represent actual places as if you're really there in 360 degrees

104
00:06:48.500 --> 00:06:52.122
So far, these have been represented mainly through HMDs

105
00:06:52.122 --> 00:06:56.100
accessing these realities through head-mounted displays, but

106
00:06:56.100 --> 00:07:01.133
as mentioned in the previous lecture, square and similar areas

107
00:07:01.133 --> 00:07:04.398
extensions of XR are also possible

108
00:07:04.398 --> 00:07:07.043
Extensions into the virtual realm are where

109
00:07:07.043 --> 00:07:08.443
much of the expansion is happening

110
00:07:09.017 --> 00:07:14.870
What are the differences between virtual and augmented reality?

111
00:07:15.385 --> 00:07:16.430
The biggest difference is

112
00:07:16.430 --> 00:07:20.460
whether it utilizes information from the real world

113
00:07:20.460 --> 00:07:24.552
In case of augmented reality, it involves using the camera

114
00:07:24.552 --> 00:07:27.120
by receiving information from the real world

115
00:07:27.120 --> 00:07:29.653
 and it operates based on that information

116
00:07:30.247 --> 00:07:34.364
But virtual reality is entering entirely new spaces, spaces that don't exist

117
00:07:34.364 --> 00:07:39.761
Even though it can recreate existing spaces, it also creates entirely new virtual reality spaces

118
00:07:40.266 --> 00:07:43.415
The data for spaces in virtual reality

119
00:07:43.415 --> 00:07:46.479
doesn't measure data from real world

120
00:07:46.479 --> 00:07:50.143
Therefore, the biggest difference between virtual reality and augmented reality is

121
00:07:50.143 --> 00:07:54.789
whether it utilizes information from the real world

122
00:07:54.789 --> 00:07:59.700
And whether it creates entirely new spaces from scratch

123
00:07:59.700 --> 00:08:04.364
it's worth considering that virtual reality can come into existence

124
00:08:05.246 --> 00:08:08.900
For examples of augmented reality

125
00:08:09.534 --> 00:08:15.540
content extensions can be seen in games like Minecraft

126
00:08:15.540 --> 00:08:19.068
It can also be exemplified in experiences like Pokemon GO

127
00:08:19.068 --> 00:08:23.480
Currently, the most promising developments could be

128
00:08:23.480 --> 00:08:26.048
applications in the logistics system

129
00:08:26.048 --> 00:08:28.310
Possible advancements in the logistics system as well

130
00:08:28.310 --> 00:08:32.083
And it can be personalized and tailored to individual needs

131
00:08:32.083 --> 00:08:35.680
It would be beneficial to consider personalized marketing ventures as potential content

132
00:08:35.680 --> 00:08:40.659
for virtual reality and augmented reality in the future

133
00:08:40.659 --> 00:08:42.876
I'm sure you all know what algorithms are

134
00:08:42.876 --> 00:08:44.973
What algorithms do you know?

135
00:08:44.973 --> 00:08:47.693
You've probably heard of

136
00:08:47.693 --> 00:08:50.500
the YouTube algorithm, the Google algorithm, and the Naver algorithm

137
00:08:50.500 --> 00:08:56.290
When you've looked into how algorithms determine what content surfaces,

138
00:08:56.290 --> 00:09:00.020
going forward, personalized content tailored to each individual

139
00:09:00.020 --> 00:09:04.792
will continue to be provided on YouTube

140
00:09:04.792 --> 00:09:06.481
Thus, some contents that you're interested in, such as

141
00:09:06.481 --> 00:09:09.979
if you're interested in politics, you'll see a lot of political content

142
00:09:09.979 --> 00:09:12.841
If you're interested in VR

143
00:09:13.406 --> 00:09:15.885
you'll find a lot of VR content

144
00:09:15.885 --> 00:09:20.219
If you're interested in artificial intelligence, you'll receive a lot of recommendations for AI content

145
00:09:20.219 --> 00:09:23.719
If you're interested in celebrities, you'll find a lot of celebrity content

146
00:09:23.719 --> 00:09:27.260
If you're interested in Hallyu (Korean Wave), you'll also find a lot of content related to that

147
00:09:27.260 --> 00:09:28.786
When you've explored these areas

148
00:09:28.786 --> 00:09:30.591
I believe people can create new algorithms

149
00:09:30.591 --> 00:09:33.213
based on these existing algorithms

150
00:09:34.332 --> 00:09:37.303
Based on the aspects that you've already formed

151
00:09:37.303 --> 00:09:40.893
through your algorithms

152
00:09:40.893 --> 00:09:44.243
I can probably tell what specific colors you like

153
00:09:44.807 --> 00:09:45.484
Can I?

154
00:09:46.008 --> 00:09:47.828
Well, based on the content

155
00:09:47.828 --> 00:09:52.370
through algorithmic analysis, it's possible to determine what specific colors people might like

156
00:09:52.370 --> 00:09:55.460
Color preference and matching outfits: Algorithmic analysis and recommendations
If, for example, when you shop online

157
00:09:55.460 --> 00:10:01.183
and looked at clothing related to the specific colors you like

158
00:10:01.183 --> 00:10:05.539
it can be seen as something that could be included in recommendations by the algorithm

159
00:10:05.539 --> 00:10:08.563
I'll imagine this scenario a bit further

160
00:10:08.563 --> 00:10:10.171
This is a product that hasn't been released yet

161
00:10:11.290 --> 00:10:13.096
The phone bends, right?

162
00:10:13.096 --> 00:10:15.962
Through a flexible display, the phone bends

163
00:10:16.566 --> 00:10:20.780
And fiber-based displays are currently being developed

164
00:10:21.473 --> 00:10:25.900
Let me share an imaginative scenario about future content

165
00:10:25.900 --> 00:10:29.752
While preparing for the lecture this morning,

166
00:10:29.752 --> 00:10:34.140
I was considering which suit to wear and looked at various colors

167
00:10:34.140 --> 00:10:36.689
There's navy blue, black

168
00:10:36.689 --> 00:10:40.981
and even charcoal gray suits, among others

169
00:10:40.981 --> 00:10:43.979
I ended up wearing the most classic black suit

170
00:10:43.979 --> 00:10:46.324
However, when I stood in front of the camera

171
00:10:46.324 --> 00:10:49.321
I started to think, "Maybe I should have worn navy blue instead?"

172
00:10:49.321 --> 00:10:51.659
and felt a slight regret

173
00:10:51.659 --> 00:10:54.947
Decisions and dilemmas in everyday life could be solved through algorithms
It seems like these aspects could be addressed in the future

174
00:10:54.947 --> 00:10:57.859
I'm imagining content right now

175
00:10:57.859 --> 00:11:02.003
It's a prudent imagination about

176
00:11:02.003 --> 00:11:04.257
whether these aspects might actually come true in 10 years

177
00:11:05.475 --> 00:11:09.251
Flexible displays have already emerged in smartphones

178
00:11:09.251 --> 00:11:10.475
The display bends

179
00:11:10.881 --> 00:11:15.007
And there's a lot of development and

180
00:11:15.007 --> 00:11:16.420
emergence of fiber-based displays right now

181
00:11:16.420 --> 00:11:18.462
So, in the future

182
00:11:18.462 --> 00:11:22.000
it's possible that suits could be made

183
00:11:22.000 --> 00:11:25.059
entirely from fiber materials like this in the future

184
00:11:25.059 --> 00:11:29.513
Someday, it's conceivable that

185
00:11:29.513 --> 00:11:32.649
there could be features on phones where you can say

186
00:11:32.649 --> 00:11:34.900
"Today, I'd like to wear this color," or "Today, I'd like to wear this pattern"

187
00:11:34.900 --> 00:11:38.110
If that were the case, using your phone in the morning

188
00:11:38.110 --> 00:11:43.358
you wouldn't buy clothes based on

189
00:11:43.358 --> 00:11:44.938
patterns like A today, B tomorrow, C the next day

190
00:11:44.938 --> 00:11:47.807
clothing becomes more like a tool

191
00:11:47.807 --> 00:11:51.781
and I think it might change into a form

192
00:11:51.781 --> 00:11:54.460
where people buy designs created by you

193
00:11:54.460 --> 00:12:01.627
In that case, industries like VR and XR, which produce immersive content

194
00:12:01.627 --> 00:12:04.179
could be seen as connected to the fashion industry

195
00:12:04.179 --> 00:12:08.467
Until now, designers and design, as well as content

196
00:12:08.477 --> 00:12:12.350
have been somewhat disconnected from industries

197
00:12:12.350 --> 00:12:14.946
That's why, in fact, design has been

198
00:12:14.946 --> 00:12:18.820
more about my own pride and satisfaction

199
00:12:18.820 --> 00:12:22.503
In reality, many people, especially older generations

200
00:12:22.503 --> 00:12:24.820
have the perception that design is something that can be done in just one day

201
00:12:24.820 --> 00:12:30.460
However, with the emergence of content and immersive experiences, there's been a significant industrial connection

202
00:12:30.460 --> 00:12:33.223
You should be aware of the significant changes

203
00:12:33.223 --> 00:12:35.976
happening in industries, which would be beneficial

204
00:12:37.144 --> 00:12:40.465
Next, we have an example of virtual reality

205
00:12:40.465 --> 00:12:43.156
Currently, the virtual reality we know of is

206
00:12:43.156 --> 00:12:47.979
primarily focused on the entertainment sector

207
00:12:47.979 --> 00:12:50.760
If you look at the cases, you might already be familiar with them

208
00:12:50.760 --> 00:12:53.739
But in this entertainment context

209
00:12:53.739 --> 00:12:57.091
the VR content we create is

210
00:12:57.091 --> 00:13:00.368
now becoming usable

211
00:13:00.368 --> 00:13:02.979
in a wide variety of fields

212
00:13:02.979 --> 00:13:07.497
While the majority of VR content is still based on devices

213
00:13:07.497 --> 00:13:11.580
like head-mounted displays (HMDs)

214
00:13:11.580 --> 00:13:18.868
these applications span across various industries including gaming, film, fine arts, design, architecture, medicine, aviation, military, etc.

215
00:13:18.868 --> 00:13:23.809
VR device Oculus/ Artwork created with VR by Giovanni Nakpil
It's reported that there's a lot of utilization happening across various fields

216
00:13:24.219 --> 00:13:26.097
Indeed, in the United States

217
00:13:27.067 --> 00:13:31.456
military personnel are actively using VR technology

218
00:13:31.456 --> 00:13:35.550
for various aspects of military training

219
00:13:35.550 --> 00:13:37.951
Samsung Electronics in South Korea, too

220
00:13:37.951 --> 00:13:44.053
They supply VR training content to the Ministry of National Defense

221
00:13:44.053 --> 00:13:46.173
where personnel wear Gear VR for virtual training

222
00:13:46.896 --> 00:13:51.133
I've analyzed some of these cases

223
00:13:51.133 --> 00:13:55.210
You can see that these technologies are also widely utilized in South Korea

224
00:13:55.210 --> 00:14:00.659
especially in reserve forces training

225
00:14:00.659 --> 00:14:04.845
And these advancements are further developed in the field of MR

226
00:14:04.845 --> 00:14:06.249
Mixed Reality

227
00:14:06.249 --> 00:14:08.615
Mixed Reality is a blend of virtual and real worlds

228
00:14:08.615 --> 00:14:12.181
This mixed reality involves real environments and augmented reality

229
00:14:12.181 --> 00:14:16.246
This includes both augmented reality and virtual reality,

230
00:14:16.246 --> 00:14:21.232
creating a digital world within the real world

231
00:14:21.232 --> 00:14:23.419
that can be integrated with augmented reality and similar technologies

232
00:14:23.419 --> 00:14:28.202
Imagine a scenario where

233
00:14:28.202 --> 00:14:29.618
these real and digital worlds merge

234
00:14:29.618 --> 00:14:35.789
While wearing the MR device, you could navigate the streets and engage in various activities

235
00:14:35.789 --> 00:14:41.933
Mixed Reality (MR) examples: Microsoft HoloLens 2 / Meta Quest 3
Could it be a world similar to the one Iron Man creates in the Avengers?

236
00:14:42.775 --> 00:14:46.341
While using MR technology, you could have you own J.A.R.V.I.S., assisting you with various tasks and providing information

237
00:14:46.341 --> 00:14:49.059
It narrates information like an encyclopedia, based on your knowledge

238
00:14:49.059 --> 00:14:52.116
But what do we have?

239
00:14:52.116 --> 00:14:58.956
We have AI from Google for Android devices, and Siri for iPhones

240
00:14:58.956 --> 00:15:02.219
With these features, currently,

241
00:15:02.219 --> 00:15:07.260
many aspects of future content depiced in Avengers movies

242
00:15:07.260 --> 00:15:11.838
are now reflected in the real world

243
00:15:11.838 --> 00:15:15.940
Apple has released products like the Apple Vision Pro

244
00:15:15.940 --> 00:15:20.524
These developments indicate

245
00:15:21.246 --> 00:15:25.859
a gradual convergence of the real and virtual worlds in our reality

246
00:15:25.859 --> 00:15:28.614
Because I was curious

247
00:15:28.614 --> 00:15:35.059
I also wanted to try out devices for Gear VR and mixed reality

248
00:15:35.059 --> 00:15:38.380
so I bought one and tried using it

249
00:15:38.380 --> 00:15:41.699
When watching movies

250
00:15:41.699 --> 00:15:46.739
you feel like you're completely immersed in the scene, as if you're right there in the square

251
00:15:46.739 --> 00:15:51.543
And when playing games, you experience a tremendous increase in immersion

252
00:15:51.543 --> 00:15:55.260
with a heightened sense of realism

253
00:15:55.260 --> 00:15:58.858
In Korea, there aren't many people

254
00:15:58.858 --> 00:16:00.724
using these devices to walk around the streets just yet

255
00:16:00.724 --> 00:16:03.979
However, I've personally seen many people doing so in the United States

256
00:16:03.979 --> 00:16:07.727
There are even people working in cafes using these devices

257
00:16:07.727 --> 00:16:10.803
Additionally

258
00:16:10.803 --> 00:16:13.435
some people use MR devices

259
00:16:13.435 --> 00:16:15.919
to walk around and view objects in real life

260
00:16:15.919 --> 00:16:19.360
And there are also people who engage in continuous conversation with Siri

261
00:16:19.360 --> 00:16:24.624
I believe that in the future, a world blended with Mixed Reality

262
00:16:24.624 --> 00:16:28.618
Virtual Reality, and XR will unfold before us

263
00:16:28.618 --> 00:16:31.790
I assume that because we anticipate such a world emerging

264
00:16:31.790 --> 00:16:37.460
it's likely why you're listening to this lecture now

265
00:16:37.460 --> 00:16:41.803
Then, if we consider whether XR was always just XR from the beginning

266
00:16:41.803 --> 00:16:44.243
the answer is likely no

267
00:16:44.243 --> 00:16:48.739
If we ask whether VR was always just VR from the beginning, the answer is likely no as well

268
00:16:48.739 --> 00:16:52.856
In fact, the origins of VR can be traced back to simulations and visualizations

269
00:16:52.856 --> 00:16:55.527
used for various purposes

270
00:16:55.527 --> 00:16:58.340
before evolving into the immersive experiences we know today

271
00:16:58.340 --> 00:17:00.555
So it started with simulators

272
00:17:00.555 --> 00:17:03.928
Then it was expressed as VR, AR, MR, XR, and so on

273
00:17:03.928 --> 00:17:09.285
It's being implemented as a time

274
00:17:09.285 --> 00:17:11.517
when we're going back to simulators based on VR and XR

275
00:17:11.517 --> 00:17:13.421
And these aspects

276
00:17:13.421 --> 00:17:18.413
now more people are buying HMDs and using them on their own

277
00:17:18.413 --> 00:17:23.298
And now there's a need for extensions of content

278
00:17:23.298 --> 00:17:27.140
that can be used beyond just wearing HMDs

279
00:17:27.140 --> 00:17:31.696
Let's delve a bit deeper

280
00:17:31.696 --> 00:17:34.803
into the technical aspects of these developments

281
00:17:34.803 --> 00:17:37.420
Now, XR technologies

282
00:17:37.420 --> 00:17:41.158
They encompass a wide range of applications across various industries

283
00:17:41.158 --> 00:17:46.380
Describing these technologies as encompassing a diverse array of capablites would be apt

284
00:17:46.380 --> 00:17:52.064
XR is currently based on tasks such as 3D scanning

285
00:17:53.262 --> 00:18:00.500
motion capture, CGI, and real-time rendering technology in Unreal Engine

286
00:18:00.500 --> 00:18:06.946
Furthermore, deep learning techniques for tactile sensation recognition through VR gloves

287
00:18:06.946 --> 00:18:12.540
are being analyzed as production elements for XR in VR

288
00:18:12.540 --> 00:18:16.526
Indeed, 3D scanning encompasses not only avatar's skeletal structures

289
00:18:16.526 --> 00:18:20.393
but also building architecture

290
00:18:20.393 --> 00:18:25.699
So, the concept of digial twin for buildings and the digital mirror world mentioned in the lecture

291
00:18:25.699 --> 00:18:30.614
can be related to the use of 3D scanning

292
00:18:30.614 --> 00:18:34.583
These days, not only do people work with actual modeling, but

293
00:18:34.583 --> 00:18:38.459
they also express concepts through 3D scanning operations

294
00:18:38.459 --> 00:18:42.590
And along with that, there's motion capture technology to capture movements and actions

295
00:18:42.590 --> 00:18:45.115
All the actions I'm doing

296
00:18:45.115 --> 00:18:48.067
they can be replicated

297
00:18:48.819 --> 00:18:53.296
by a 3D-scanned avatar with natural movements

298
00:18:53.296 --> 00:18:57.180
This capability can be implemented not only with high-end equipment

299
00:18:57.180 --> 00:19:00.670
But also with the smartphones you already have

300
00:19:00.670 --> 00:19:04.180
which is worth mentioning

301
00:19:04.180 --> 00:19:06.565
So, as you can see on your phones

302
00:19:06.565 --> 00:19:10.019
most come equipped with at least two to three built-in cameras

303
00:19:10.019 --> 00:19:13.969
One is known as a depth camera, and the other is an RGB camera

304
00:19:13.969 --> 00:19:17.900
One is based on vision cameras, including IR cameras

305
00:19:17.900 --> 00:19:22.217
Smartphones with three lenses, including depth-sensing and vision cameras

306
00:19:22.217 --> 00:19:27.979
can perform motion capture tasks

307
00:19:27.979 --> 00:19:32.712
In addition, CGI technology, which stands for Computer-Generated Imagery

308
00:19:32.712 --> 00:19:36.060
refers to the process of generating and manipulating visual content using computer software

309
00:19:36.060 --> 00:19:39.939
It's one of the oldest and most foundational technologies in the realm of digital graphics

310
00:19:39.939 --> 00:19:44.260
You could also think of CGI as advanced post-processing for achieving high-quality visual effects

311
00:19:44.260 --> 00:19:46.056
In the past

312
00:19:46.056 --> 00:19:49.773
when creating content based on 3D

313
00:19:49.773 --> 00:19:54.939
All of these elements were primarily developed through rendering technologies

314
00:19:54.939 --> 00:19:58.525
The content created through Unreal Engine and Unity Engine, for example

315
00:19:58.525 --> 00:20:01.955
Live techniques allow for the expression of realistic aspects in real time

316
00:20:01.955 --> 00:20:05.300
even those previously rendered

317
00:20:05.300 --> 00:20:06.753
The following is deep learning

318
00:20:06.753 --> 00:20:11.150
If artificial intelligence technology is incorporated here, it woud enable the creation of higher quality textures

319
00:20:11.150 --> 00:20:16.819
and backgrounds for the technologies that one's developing

320
00:20:16.819 --> 00:20:23.028
Additionally, you can see that gloves and head-mounted can provide

321
00:20:23.028 --> 00:20:27.110
input-sensing that allows for more diverse expressions

322
00:20:27.110 --> 00:20:31.140
through facial expressions and other features

323
00:20:31.140 --> 00:20:34.668
Based on these aspects, it would be good to see that the metaverse platform

324
00:20:34.668 --> 00:20:37.387
it would be good to see that the metaverse platform

325
00:20:37.387 --> 00:20:39.819
can create a wider variety of XR experiences

326
00:20:39.819 --> 00:20:42.446
These aspects allow

327
00:20:42.446 --> 00:20:47.080
for the creation of content in real-time

328
00:20:47.080 --> 00:20:50.860
based on various hardware and motion capture

329
00:20:50.860 --> 00:20:54.540
utilizing diverse inputs

330
00:20:54.540 --> 00:20:57.947
While the performance of the device is also very important

331
00:20:57.947 --> 00:21:01.357
Because device performance has improved significantly

332
00:21:01.357 --> 00:21:03.453
You can see that there are hardly any content

333
00:21:03.453 --> 00:21:08.739
that are being created now that cannot be run

334
00:21:08.739 --> 00:21:11.595
Furthermore

335
00:21:11.595 --> 00:21:14.645
As these aspects become more diverse in terms of devices and sensors

336
00:21:14.645 --> 00:21:19.660
The applications of XR technology are increasingly expanding

337
00:21:19.660 --> 00:21:24.660
Particularly centered around simulators

338
00:21:24.660 --> 00:21:29.699
In fields such as manufacturing, healthcare, education, culture, and defense

339
00:21:29.699 --> 00:21:32.604
Based on these aspects

340
00:21:33.476 --> 00:21:37.550
You can also see that XR can no longer exclude elements

341
00:21:37.550 --> 00:21:40.619
Such as artificial intelligence

342
00:21:40.619 --> 00:21:43.597
These, including artificial intelligence, now involve creating virtual assistants

343
00:21:43.597 --> 00:21:47.203
So, what we were talking about earlier - creating a virtual assistant -

344
00:21:47.203 --> 00:21:50.150
is actually content

345
00:21:50.150 --> 00:21:56.702
However, the technologies that transform what I'm saying into text

346
00:21:56.702 --> 00:22:01.739
and translate into different languages

347
00:22:01.739 --> 00:22:04.330
can be summarized as aspects of artificial intelligence

348
00:22:04.330 --> 00:22:07.110
within the context of virtual assistants

349
00:22:07.110 --> 00:22:12.261
These could lead to a future

350
00:22:12.261 --> 00:22:16.001
where you can naturally utilize everything

351
00:22:16.001 --> 00:22:19.346
by simply wearing earphones

352
00:22:19.346 --> 00:22:21.699
similar to how you might wear earbuds or AirPods now with your Buzz or iPhone

353
00:22:21.699 --> 00:22:25.796
When these aspects become more commercialized

354
00:22:25.796 --> 00:22:28.001
for mixed reality (MR) devices

355
00:22:28.001 --> 00:22:33.260
They can be expressed in a much broader range of applications

356
00:22:33.260 --> 00:22:39.417
Then why would we want to express these aspects of XR?

357
00:22:40.516 --> 00:22:44.160
Why would XR be suitable for industries?

358
00:22:44.160 --> 00:22:46.619
We can actually create real content

359
00:22:46.619 --> 00:22:50.909
Why would industries consider transitioning to XR virtual and augmented reality worlds

360
00:22:50.909 --> 00:22:53.050
transitioning to XR virtual and augmented reality worlds

361
00:22:53.050 --> 00:22:58.755
when they already have existing content to work with?

362
00:22:59.398 --> 00:23:01.201
Would you like to think about it for a moment?

363
00:23:03.320 --> 00:23:06.970
These factors are also evolving in tandem

364
00:23:06.970 --> 00:23:10.381
with our environmental impact

365
00:23:11.133 --> 00:23:17.660
I think you've probably heard a lot about ESG (Environmental, Social, and Governance) issues worldwide

366
00:23:17.660 --> 00:23:21.357
There are indeed many issues related to the environment being addressed

367
00:23:21.357 --> 00:23:24.667
These aspects are also relevant to virtual reality and augmented reality

368
00:23:24.667 --> 00:23:28.336
XR Benefit 1: Waste Reduction
And XR helps to reduce waste

369
00:23:28.336 --> 00:23:30.728
Since separate training facilities are not built

370
00:23:30.728 --> 00:23:35.518
It means that training can be conducted multiple times without being discarded after a single use

371
00:23:35.518 --> 00:23:36.971
Because it is a content

372
00:23:36.971 --> 00:23:39.202
XR Benefit 2: Cost Reduction
And it can reduce costs

373
00:23:40.014 --> 00:23:42.278
Content related to these aspects

374
00:23:42.278 --> 00:23:45.540
Content that is created once and then discarded

375
00:23:45.540 --> 00:23:47.622
needs to be continually discarded

376
00:23:47.622 --> 00:23:50.932
Therefore, it needs to be continually produced

377
00:23:50.932 --> 00:23:54.099
However, virtual content that is produced once

378
00:23:54.099 --> 00:23:57.782
can be continuously utilized

379
00:23:57.782 --> 00:24:01.979
XR Benefit 3: Improved Understanding
Additionally, it can enhance comprehension

380
00:24:01.979 --> 00:24:05.542
XR Benefit 4: Project Efficiency
And it allows for efficient project management

381
00:24:05.542 --> 00:24:10.663
Because it's essentially composed of virtual elements

382
00:24:10.663 --> 00:24:13.720
XR Benefit 5: Enhanced Safety
Safety is extended and improved

383
00:24:13.720 --> 00:24:19.219
XR Benefit 6: Better Decision Making
It can even lead to better decision-making, making a total of six benefits

384
00:24:19.219 --> 00:24:25.237
We anticipate that these aspects will expand further in the future

385
00:24:25.237 --> 00:24:29.097
due to environmental and ESG considerations

386
00:24:29.813 --> 00:24:33.733
Sensor-based interaction research

387
00:24:33.733 --> 00:24:36.489
XR technology encompasses various sensors

388
00:24:36.489 --> 00:24:42.646
User movements, positions, voice, emotions, and more

389
00:24:42.646 --> 00:24:46.300
It involves collecting various information

390
00:24:46.300 --> 00:24:48.921
and reflecting it in the virtual environment

391
00:24:48.921 --> 00:24:52.370
So, because of these aspects

392
00:24:52.370 --> 00:24:55.699
It's often tied closely to the real world

393
00:24:55.699 --> 00:24:59.188
Augmented reality similarly relies heavily on various sensor-based foundations

394
00:24:59.188 --> 00:25:02.264
for its expression

395
00:25:02.264 --> 00:25:06.063
Actually, you could say that

396
00:25:06.063 --> 00:25:08.595
Each of you also has these sensors one by one

397
00:25:09.328 --> 00:25:12.596
Gyroscope and accelerometer sensors
Both the gyroscope and the accelerometer sensors are present in VR devices as well

398
00:25:12.596 --> 00:25:15.986
This gyroscope sensor is calibrated based on gravity here

399
00:25:15.986 --> 00:25:22.402
aligning with movements accordingly

400
00:25:22.402 --> 00:25:26.060
It initially started as a sensor primarily for gaming purposes

401
00:25:26.060 --> 00:25:30.167
Various contents are being developed

402
00:25:30.167 --> 00:25:33.184
Based on these sensor foundations

403
00:25:33.184 --> 00:25:35.302
You've probably seen a lot of content on mobile devices

404
00:25:36.401 --> 00:25:41.301
Where you tilt to control the movement

405
00:25:41.301 --> 00:25:44.793
Thus, these contents are expressed

406
00:25:44.793 --> 00:25:49.801
through the interactions with sensors

407
00:25:49.801 --> 00:25:52.210
found in mobile and smartphones, among others

408
00:25:52.210 --> 00:25:54.053
And there's also the accelerometer sensor

409
00:25:54.053 --> 00:25:57.014
Using various sensors

410
00:25:57.014 --> 00:26:00.438
The accelerometer measures

411
00:26:00.438 --> 00:26:06.699
The current position and the next position to determine the acceleration

412
00:26:06.699 --> 00:26:12.015
The current position is determined based on past positions

413
00:26:12.015 --> 00:26:15.314
The sensor also incorporates aspects like velocity

414
00:26:15.314 --> 00:26:21.371
assessing how much movement occurs within a certain time frame

415
00:26:21.371 --> 00:26:24.231
Say, in one second

416
00:26:24.231 --> 00:26:27.245
It allows for a more extensive expression of the interaction

417
00:26:27.245 --> 00:26:31.060
in VR

418
00:26:31.060 --> 00:26:32.520
and XR

419
00:26:32.520 --> 00:26:36.400
Next up is the motion sensor, what is a motion sensor?

420
00:26:36.400 --> 00:26:41.168
It's a sensor that detects gestures and motions to express actions

421
00:26:41.168 --> 00:26:44.665
In the past, motion sensors typically relied on recognizing this kind of shape

422
00:26:44.665 --> 00:26:49.520
(A rectangle cut in half-like shape) to initiate recognition

423
00:26:49.520 --> 00:26:52.674
Nowadays, content based on human skeletons can be extracted

424
00:26:52.674 --> 00:26:57.180
Not only from specialized motion cameras

425
00:26:57.180 --> 00:26:58.739
But also from regular cameras

426
00:26:58.739 --> 00:27:01.016
It recognizes human faces as well

427
00:27:01.016 --> 00:27:04.806
By recognizing the face

428
00:27:04.806 --> 00:27:07.934
It can then extend recognition to the hands, feet, and individual joints

429
00:27:07.934 --> 00:27:10.748
Now, it's possible to recognize human motion

430
00:27:10.748 --> 00:27:13.430
incorporating recognition of various body parts

431
00:27:13.430 --> 00:27:16.257
Radar sensors that utilize electromagnetic waves
Next up is the laser sensor

432
00:27:16.257 --> 00:27:20.540
In reality, laser sensors could be based on devices like laser pointers

433
00:27:20.540 --> 00:27:25.240
The ones you see used in presentations or lectures

434
00:27:25.240 --> 00:27:28.422
Actually, these laser sensors can also display colors in various ways

435
00:27:28.422 --> 00:27:29.900
Right now, it's emitting red light

436
00:27:29.900 --> 00:27:33.214
It can also display the red as blue

437
00:27:33.690 --> 00:27:35.500
It can also be expressed as green

438
00:27:35.500 --> 00:27:37.886
And in fact, it can also be represented as sensors

439
00:27:37.886 --> 00:27:41.380
that utilize forms invisible to the naked eye using visible light

440
00:27:41.380 --> 00:27:45.778
So, by positioning the sensor from under the palm of the hand to above it

441
00:27:46.194 --> 00:27:51.739
It can diversify the content accordingly

442
00:27:51.739 --> 00:27:56.574
And these aspects enable the expression of content in a wider variety of forms

443
00:27:56.574 --> 00:28:00.772
Speaking of these laser sensors

444
00:28:00.772 --> 00:28:04.568
They can actually indicate whether a person has passed by

445
00:28:04.568 --> 00:28:06.450
representing the flow of movement

446
00:28:06.955 --> 00:28:07.884
It can also detect speed

447
00:28:07.884 --> 00:28:12.678
The utilization of laser sensors involves

448
00:28:12.678 --> 00:28:15.373
expressing applications in various fields

449
00:28:15.373 --> 00:28:17.500
each focusing on the detection of flow

450
00:28:17.500 --> 00:28:21.246
through the first and last sensors

451
00:28:21.246 --> 00:28:23.429
Next up is the voltage sensor

452
00:28:23.429 --> 00:28:27.760
The Capacitive Touch Sensor detects changes in electrical capacitance to determine user contact
These sensors are commonly used in smartphones

453
00:28:27.760 --> 00:28:34.676
In fact, older smartphones used pressure sensors rather than capacitive touch sensors

454
00:28:34.676 --> 00:28:39.676
So, they recognized when pressure applied

455
00:28:39.676 --> 00:28:43.458
Nowadays, it's not the pressure applied

456
00:28:43.458 --> 00:28:49.511
But rather the user's touch sensation based on their electrical capacitance

457
00:28:49.957 --> 00:28:53.639
Therefore, it detects regular changes in capacitance to sense the user's touch sensation

458
00:28:53.639 --> 00:28:56.976
When it's applied to clothing or similar items, it prevents responses based on user contact

459
00:28:56.976 --> 00:29:03.154
and instead detects changes in capacitance

460
00:29:03.154 --> 00:29:07.601
These aspects are expressed through the touch method of capacitive touch sensors

461
00:29:07.601 --> 00:29:11.232
These aspects are utilized in various industries such as homes

462
00:29:11.232 --> 00:29:15.089
Such as homes, smartphones, automotive systems

463
00:29:15.089 --> 00:29:18.459
and electrical control systems

464
00:29:18.459 --> 00:29:24.037
The utilization of capacitive touch is

465
00:29:24.037 --> 00:29:26.606
indeed extensive

466
00:29:27.447 --> 00:29:31.229
In sensor-based interaction, there are also image sensors

467
00:29:31.229 --> 00:29:36.073
An image Sensor reads object information and converts it into electrical image signals
This image sensor is a device that

468
00:29:36.073 --> 00:29:42.049
converts visual information into electrical signals, essentially what cameras do

469
00:29:42.049 --> 00:29:46.764
These components convert the light from real-world objects into electrical energy

470
00:29:47.595 --> 00:29:51.099
transforming it into digital signals

471
00:29:51.772 --> 00:29:57.270
which allows physical scenes to be captured and rendered digitally

472
00:29:57.270 --> 00:29:59.130
The size of the image sensor directly determines the quality and resolution of the images you see

473
00:30:00.140 --> 00:30:03.032
Larger sensors typically capture more light and detail

474
00:30:03.032 --> 00:30:05.140
leading to higher-quality images

475
00:30:05.140 --> 00:30:08.536
The image sensor is crucial when transitioning from the physical world to the virtual world

476
00:30:08.536 --> 00:30:11.836
As it serves as the core technology that captures

477
00:30:11.836 --> 00:30:15.140
and converts real-world objects into digital signals

478
00:30:15.140 --> 00:30:17.385
The next component is the GPS sensor

479
00:30:17.385 --> 00:30:19.707
Satellite-based Navigation System: GPS
What is a GPS sensor?

480
00:30:20.341 --> 00:30:21.985
GPS sensor receives signals transmitted from the satellites

481
00:30:22.579 --> 00:30:26.194
So, based on the signals sent from these satellites

482
00:30:27.045 --> 00:30:30.819
The current location of the user is determined

483
00:30:30.819 --> 00:30:34.894
Therefore, in a way, one of the most common applications of GPS sensors is

484
00:30:34.894 --> 00:30:38.020
navigation system

485
00:30:38.020 --> 00:30:42.695
Things like your metro card or other similar systems

486
00:30:42.695 --> 00:30:46.339
often rely on GPS-based technology for distance-based integration

487
00:30:46.339 --> 00:30:51.815
These applications are widely used in various fields such as navigation for sailing

488
00:30:51.815 --> 00:30:54.638
aviation, automotive navigation, hiking, and fitness tracking

489
00:30:54.638 --> 00:30:59.606
Recently, there has been a trend towards creating content

490
00:30:59.606 --> 00:31:04.099
that shows outdoor landscapes and environments

491
00:31:04.099 --> 00:31:08.398
As these areas become more diverse

492
00:31:08.398 --> 00:31:12.379
They are based on indoor positioning systems

493
00:31:12.379 --> 00:31:14.391
Contents based on Wi-Fi positioning

494
00:31:14.391 --> 00:31:18.421
The development of technologies that measure

495
00:31:18.421 --> 00:31:22.243
indoor positioning

496
00:31:22.243 --> 00:31:24.440
based on the distance of Wi-Fi signals is also considered

497
00:31:24.440 --> 00:31:26.388
It's likely that services based on these technologies

498
00:31:26.388 --> 00:31:29.998
will become increasingly common in the future

499
00:31:29.998 --> 00:31:36.895
In reality, due to Korea being a country that's technically at war or in a ceasefire situation

500
00:31:36.895 --> 00:31:41.269
Its industries may not have flourished as much as those in peaceful countries

501
00:31:41.269 --> 00:31:44.522
However, in countries like the United States and others

502
00:31:44.522 --> 00:31:49.581
The signals from GPS satellites are being leveraged

503
00:31:49.581 --> 00:31:54.212
for various forward-looking commercial ventures in the private sector

504
00:31:54.955 --> 00:31:59.560
In places like the California desert

505
00:31:59.560 --> 00:32:03.140
You can witness scenes where private satellites are actually being launched

506
00:32:03.140 --> 00:32:04.997
The gyroscope sensor detects and measures rotation speed
Next up is the gyroscope sensor

507
00:32:04.997 --> 00:32:10.339
It detects and measures the rate of rotation

508
00:32:10.339 --> 00:32:13.429
It's expressing that a lot of movement can be represented

509
00:32:14.864 --> 00:32:18.479
based on content using gyro sensors

510
00:32:18.479 --> 00:32:22.088
The gyro sensor-based content is widely utilized in drone-related aspects

511
00:32:22.088 --> 00:32:25.489
to represent such activities

512
00:32:25.489 --> 00:32:29.741
In drone sensors

513
00:32:29.741 --> 00:32:32.420
Gyro sensors are extensively used to depict rotation and movement

514
00:32:32.420 --> 00:32:35.519
So, the drone you're seeing now is

515
00:32:35.519 --> 00:32:38.444
based on four gyro sensors

516
00:32:40.514 --> 00:32:44.420
to control its movement

517
00:32:44.420 --> 00:32:48.554
You can consider these sensors as part of a composite sensing system

518
00:32:48.554 --> 00:32:53.044
that contributes to a sense of realism

519
00:32:53.724 --> 00:32:57.595
The convergence of cutting-edge technology and content in the field

520
00:32:57.595 --> 00:33:02.104
In such various sensors

521
00:33:02.104 --> 00:33:04.779
it's fascinating how various emerging technologies are shaping content creation

522
00:33:04.779 --> 00:33:09.014
across different fields

523
00:33:09.014 --> 00:33:12.957
XR technologies are revolutionizing the architecture and engineering construction industries

524
00:33:12.957 --> 00:33:16.702
by integrating sensors

525
00:33:16.702 --> 00:33:22.370
and content creation in immersive environments

526
00:33:22.370 --> 00:33:23.608
For another example

527
00:33:24.430 --> 00:33:28.172
XR in the automotive industry encompasses various aspects

528
00:33:28.984 --> 00:33:33.442
Electric vehicles can be seen as a combination intermediary

529
00:33:33.442 --> 00:33:40.163
for the integrated aspects of these sensors and content in terms of XR

530
00:33:40.163 --> 00:33:43.540
These aspects, before actual construction

531
00:33:43.540 --> 00:33:46.347
are based on virtual simulators

532
00:33:46.347 --> 00:33:50.921
In fact, it's even possible to refine these aspects further

533
00:33:50.921 --> 00:33:56.945
to conduct prototyping on a smaller scale

534
00:33:56.945 --> 00:34:01.034
XR in media and entertainment

535
00:34:01.034 --> 00:34:07.670
VR games, chat apps with augmented reality, AR filters, virtual exhibitions, and more are

536
00:34:07.670 --> 00:34:10.866
increasingly becoming integrated into your daily life

537
00:34:10.866 --> 00:34:13.419
in various recommended forms

538
00:34:14.033 --> 00:34:15.904
And various aspects can be seen as content-convertible from diverse sensing

539
00:34:15.904 --> 00:34:21.904
as content-convertible from diverse sensing

540
00:34:21.904 --> 00:34:24.357
based on motion recognition sensors

541
00:34:24.357 --> 00:34:27.627
mentioned earlier

542
00:34:27.627 --> 00:34:31.943
NEWJAK's Laser Training: Simulation training for avoiding lasers
The content you're currently seeing is

543
00:34:31.943 --> 00:34:37.973
an e-sports style experience based on LiDAR sensor technology

544
00:34:37.973 --> 00:34:41.436
See this as an example of

545
00:34:41.436 --> 00:34:45.350
How LiDAR sensor technology is used to recognize users and

546
00:34:45.350 --> 00:34:49.345
How it's utilized to create content for e-sports

547
00:34:49.345 --> 00:34:51.717
without the need for multiple users

548
00:34:51.717 --> 00:34:54.201
to wear sensors

549
00:35:25.637 --> 00:35:33.459
NEWJAK's XR Shooting Simulator: Body movements using gyroscope sensors
Another example is using sensors for firearms in XR, based on infrared (IR) technology

550
00:35:33.459 --> 00:35:40.419
and representing various silhouettes of firearms positions as part of XR content

551
00:35:40.419 --> 00:35:46.414
using methods that don't involve wearing traditional HMD VR headsets

552
00:35:46.414 --> 00:35:51.488
users could potentially enjoy content in a format

553
00:35:51.488 --> 00:35:57.419
where they can physically move around

554
00:35:57.419 --> 00:35:59.419
without having to wear a traditional VR headset

555
00:35:59.419 --> 00:36:05.107
These aspects are combined in a way

556
00:36:05.107 --> 00:36:08.775
that effectively expresses the RDW (Realistic Digital World) technology

557
00:36:08.775 --> 00:36:12.244
NEWJAK's RDW applied on Dobong-ro
When it comes to VR cave setups

558
00:36:12.244 --> 00:36:15.478
and Redirected Walking (RDW)

559
00:36:15.983 --> 00:36:20.693
we might see a convergence of various forms of content

560
00:36:20.693 --> 00:36:23.072
into more expansive spaces

561
00:36:23.825 --> 00:36:28.308
In fact

562
00:36:28.308 --> 00:36:33.637
VR content, because of wearing goggles, has lines

563
00:36:33.637 --> 00:36:36.289
so you can't move straight ahead

564
00:36:36.289 --> 00:36:40.037
However, in a cave-like structure

565
00:36:40.037 --> 00:36:43.360
if you continue straight ahead in XR format, you'll bump into the wall

566
00:36:44.072 --> 00:36:48.821
In such cases, it would be beneficial

567
00:36:48.821 --> 00:36:53.201
to consider the use of visual illusion effects to subtly redirect the user

568
00:36:53.201 --> 00:36:55.419
making them turn slightly as if circling around

569
00:36:55.419 --> 00:36:58.746
You could observe

570
00:36:58.746 --> 00:37:01.766
a wide variety of technologies related to XR

571
00:37:01.766 --> 00:37:06.046
NEWJAK's Motion Detection Illustration
And in another way

572
00:37:06.789 --> 00:37:08.815
interactive forms in galleries could be like

573
00:37:08.815 --> 00:37:13.447
the paintings in Harry Potter that

574
00:37:13.447 --> 00:37:16.231
continuously interact with the audience

575
00:37:16.874 --> 00:37:19.174
The artworks could be adapted to show

576
00:37:19.174 --> 00:37:21.825
the kind of art that each viewer prefers

577
00:37:21.825 --> 00:37:26.417

These features can be expressed

578
00:37:26.417 --> 00:37:28.993
simply through a touch wall interface

00:37:28.993 --> 00:37:31.768
The Wonyeong Flower at the Naju Immersive Content Experience Zone
Motion recognition technology is now

580
00:37:32.213 --> 00:37:37.419
commonly used to create interactive content

581
00:37:37.419 --> 00:37:40.077
Such as particles

582
00:37:40.077 --> 00:37:42.667
or flowers that respond to movements

583
00:37:42.667 --> 00:37:46.735
The Light Playground at Jungang Art Center
Additionally, particle generation and

584
00:37:47.220 --> 00:37:50.855
content interaction based on LiDAR sensors

585
00:37:50.855 --> 00:37:54.043
could become more prevalent

586
00:37:54.053 --> 00:37:57.649
Besides these, there are sensors and other foundational technologies for content

587
00:37:57.649 --> 00:38:01.033
that haven't been released yet

588
00:38:01.033 --> 00:38:07.208
And I think we could see much more utilization

589
00:38:07.208 --> 00:38:10.518
in various industrial sectors that we haven't discussed yet

590
00:38:10.518 --> 00:38:12.998
So, I've talked about

591
00:38:12.998 --> 00:38:15.627
some challenging sensor-based technologies

592
00:38:15.627 --> 00:38:18.512
and the immersive aspects associated with them

593
00:38:18.512 --> 00:38:20.667
Considering these aspects

594
00:38:20.667 --> 00:38:23.274
I suggest you to imagine

595
00:38:23.274 --> 00:38:27.612
what kind of content you could create

596
00:38:27.612 --> 00:38:29.241
based on these elements?

597
00:38:29.241 --> 00:38:33.267
If you feel a bit lacking in imagination for that creativity

598
00:38:33.267 --> 00:38:38.746
Why not try recreating existing content from movies or other references?

599
00:38:38.746 --> 00:38:43.667
It could be a great way to experiment and get inspired

600
00:38:43.667 --> 00:38:48.696
By doing so

601
00:38:49.231 --> 00:38:54.232
You can explore and expand upon XR immersive content as content planners

602
00:38:54.232 --> 00:38:57.188
It's an exciting prospect for

603
00:38:57.188 --> 00:38:59.568
creating a variety of XR experiences

604
00:38:59.568 --> 00:39:00.330
That's all for now
