1
00:00:00,040 --> 00:00:05,520
when you're playing a video game you want to feel immersed as much as

2
00:00:03,800 --> 00:00:09,440
possible you want your character to feel like an extension of yourself you want

3
00:00:07,640 --> 00:00:12,759
to see what they see hear what they hear feel what they feel and when an enemy

4
00:00:11,320 --> 00:00:17,119
suddenly lunges out of nowhere you want to let out just a little bit of pee but

5
00:00:15,160 --> 00:00:22,320
isn't there a sense where leaving out is it really enough that I can see here and

6
00:00:19,279 --> 00:00:24,240
feel Kratos what if I could also smell

7
00:00:22,320 --> 00:00:29,119
Kratos taste him maybe not that is exactly the kind

8
00:00:27,119 --> 00:00:34,040
of question that startup game send makers of game sent is hoping to answer

9
00:00:31,599 --> 00:00:38,440
with a recently released game sent scent system which they claim automatically

10
00:00:36,040 --> 00:00:43,480
translates onscreen action into a number of cents that number being six and those

11
00:00:40,760 --> 00:00:47,960
cents being Forest gunfire storm explosion racing cars and a neutal

12
00:00:46,199 --> 00:00:53,120
pallet cleanser they've also got a few upcoming scents like ocean fresh cut

13
00:00:50,280 --> 00:00:57,559
grass sports arena and blood the perfect combination of smells to simulate Mario

14
00:00:55,039 --> 00:01:01,519
Tennis but is this the future of hyper immersive video games or just another

15
00:00:59,480 --> 00:01:06,600
Flash in the pan gimmick well let's look at the history of smellable media and

16
00:01:03,879 --> 00:01:10,360
see if past is prologue a few theaters and Cinemas experimented with adding

17
00:01:08,200 --> 00:01:14,840
sense to performances in the late 19th and early 20th century it's hard to know

18
00:01:12,439 --> 00:01:18,520
exactly what audiences thought of this back then they didn't have Rotten

19
00:01:16,280 --> 00:01:22,880
Tomatoes so they just threw literal Rotten Tomatoes in smaller venues they

20
00:01:21,000 --> 00:01:27,600
might use a cloth soaked with scented oil and a fan to waft the desired smell

21
00:01:25,439 --> 00:01:30,759
across the audience but in larger venues they typically just pumped perfume in

22
00:01:29,320 --> 00:01:35,439
through the ventil ation system or sprayed it down from the ceiling of

23
00:01:32,920 --> 00:01:40,320
course this required a lot of perfume to pull off and the smell tended to linger

24
00:01:38,119 --> 00:01:43,600
sometimes for days afterward that's a problem both because it's potentially

25
00:01:41,680 --> 00:01:48,079
expensive and because it means that it's hard to switch between scents without

26
00:01:45,719 --> 00:01:51,920
them winding up mixed and muddled piling up on each other just imagine if you

27
00:01:50,119 --> 00:01:56,560
went to see mamam Mia in the theater and it still smelled like the Fast and the

28
00:01:53,680 --> 00:02:00,240
Furious in there smells like family or you get home and your wife demands to

29
00:01:58,039 --> 00:02:03,920
know why you smell like Mulan roue it was also easy for the film or play to

30
00:02:02,079 --> 00:02:07,960
have already moved on by the time the smell really hit you it's also notable

31
00:02:05,880 --> 00:02:12,319
that these experiments were mostly done by venue owners rather than filmmakers

32
00:02:10,360 --> 00:02:16,760
meaning that the audience getting misted with perfume like a fancy vegetable

33
00:02:14,440 --> 00:02:20,480
wasn't necessarily the experience intended by the creator of the content

34
00:02:19,040 --> 00:02:25,400
one of the first filmmakers known to have considered including sense was Walt

35
00:02:22,319 --> 00:02:28,120
Disney as part of 1940s Fantasia though

36
00:02:25,400 --> 00:02:31,920
this was dropped due to expense perhaps the most famous of these early

37
00:02:29,480 --> 00:02:37,080
experiments was smello Vision originally called covision which was demonstrated

38
00:02:33,920 --> 00:02:39,239
at the 1939 World Fair smello Vision

39
00:02:37,080 --> 00:02:43,080
used a system of connected pipes which all fed to individual theater seats

40
00:02:41,120 --> 00:02:47,239
thereby allowing the amount and timing of the scent to be tightly controlled by

41
00:02:45,040 --> 00:02:51,560
the projectionist smell Vision got a lot of excited press coverage but the film

42
00:02:49,280 --> 00:02:55,519
industry they just weren't interested in part because it wasn't cheap for a

43
00:02:53,080 --> 00:03:03,040
theater to install an estimated $25 to $30 per seat as of 1959 around 250 $50

44
00:03:00,040 --> 00:03:05,560
to $300 in real terms the original smell

45
00:03:03,040 --> 00:03:10,560
of vision only wound up in one movie 1960s scent of mystery where the smells

46
00:03:08,720 --> 00:03:15,400
were designed to provide important hints about the film's plot unfortunately the

47
00:03:12,720 --> 00:03:19,319
film was a massive stinker making back only 15% of its budget also while some

48
00:03:17,920 --> 00:03:23,879
of the smells were pretty accurate others weren't and still others were

49
00:03:21,319 --> 00:03:27,840
accurate but too revolting to really be desirable modern day showings of scent

50
00:03:26,120 --> 00:03:32,200
of mystery typically use a system of scratch and sniff cards instead Which is

51
00:03:30,080 --> 00:03:35,720
far cheaper more of a distraction than an integrated part of the experience you

52
00:03:34,159 --> 00:03:40,599
can also still experience something like smell of vision at Select theaters that

53
00:03:37,519 --> 00:03:43,000
offer 4dx experiences which also involve

54
00:03:40,599 --> 00:03:47,000
haptic vibrations wind water fog and occasionally bubbles various researchers

55
00:03:45,480 --> 00:03:51,159
and entrepreneurs have played with the idea of a home version of smellable

56
00:03:49,239 --> 00:03:55,319
media but outside of scratch and sniff Concepts it largely hasn't been

57
00:03:52,720 --> 00:03:59,920
economically viable enough to even go to market there was that one VR sense

58
00:03:57,879 --> 00:04:03,400
system developer kit that was covered by our sister Channel lus Tech tips but

59
00:04:01,720 --> 00:04:07,760
it's difficult to tell how much progress they've made towards an actual consumer

60
00:04:05,239 --> 00:04:12,120
product in the time since we covered it but if smell Vision the concept not the

61
00:04:09,720 --> 00:04:17,720
20th century product has never ever worked on a broad scale why does anyone

62
00:04:14,840 --> 00:04:21,440
think it could work now how are modern video games a better choice for

63
00:04:19,320 --> 00:04:24,360

73
00:04:59,720 --> 00:05:06,360
and apply it to video games can products like gam scent actually overcome the

74
00:05:04,280 --> 00:05:10,039
pitfalls we've discussed can smell Vision perhaps gain a to hold NVIDIA

75
00:05:08,360 --> 00:05:14,800
games where it's been unsuccessful in television the Baseline bar that a

76
00:05:12,320 --> 00:05:18,919
modern smellable medium needs to surpass is technical competence and ease of use

77
00:05:17,360 --> 00:05:23,680
first it needs to provide the player with a clear recognizable scent in sync

78
00:05:21,639 --> 00:05:27,000
with the action on the screen this is pretty easily accomplished through a

79
00:05:25,160 --> 00:05:30,720
small module placed on your desk or a nearby tripod you could also probably

80
00:05:28,960 --> 00:05:33,880
use a mask of of some kind to pump the scent directly into your face holes

81
00:05:32,479 --> 00:05:38,520
that's probably where we begin to see a clear trade-off in terms of comfort

82
00:05:36,160 --> 00:05:42,560
which might negate the immersion benefit it's very likely that similar to early

83
00:05:40,360 --> 00:05:47,520
VR smelly video games will only see limited consumer uptake and consequently

84
00:05:44,960 --> 00:05:51,560
limited developer support which can be a self-reinforcing cycle gam scent though

85
00:05:49,800 --> 00:05:56,880
proposes getting around the need to have individual developers add smell support

86
00:05:54,400 --> 00:06:00,840
by using Advanced AI to Simply process what's happening in the game and

87
00:05:58,280 --> 00:06:05,360
generate appropriate sense accordingly finally AI to the rescue due to the

88
00:06:03,199 --> 00:06:09,039
tendency for sense to linger because they're literally molecules hanging in

89
00:06:07,000 --> 00:06:13,960
the air and going up your nose video game sense would probably work best as a

90
00:06:11,039 --> 00:06:17,520
subtle ambient background smell like grass when you're standing in a virtual

91
00:06:15,400 --> 00:06:21,880
Meto there might even be some value in playing a VR racing game and actually

92
00:06:19,120 --> 00:06:25,560
being able to smell fresh asphalt with a hint of burnt rubber so long as it's

93
00:06:23,680 --> 00:06:29,560
relatively subtle in a tight narrative experience like a good film like we

94
00:06:27,440 --> 00:06:33,000
talked about before it's all cut relatively fast with scenes typically

95
00:06:31,319 --> 00:06:37,319
lasting at most a few minutes and jumping quickly between times and

96
00:06:34,759 --> 00:06:41,599
locations NVIDIA games however you're usually following the action in real

97
00:06:39,240 --> 00:06:45,720
time allowing for a gradual transition between smells that feels more natural

98
00:06:44,199 --> 00:06:49,680
another issue to overcome is simply the range of smells available in current

99
00:06:47,599 --> 00:06:55,000
video game systems which includes both game scent and predecessor oselia unlike

100
00:06:52,639 --> 00:06:59,960
with color there isn't a small set of primary smells that can be combined to

101
00:06:57,440 --> 00:07:04,160
create every other smell it doesn't work like that you're going to need more than

102
00:07:01,680 --> 00:07:08,280
six cents to capture the range of most gaming experiences plus while our scent

103
00:07:06,919 --> 00:07:14,560
imitating abilities have definitely gotten more sophisticated since the 1960s there's still a lot of stuff we

104
00:07:12,240 --> 00:07:19,000
don't know how to fake well smellable media done well also requires easy

105
00:07:16,840 --> 00:07:23,879
customizability because while many players probably don't want to smell

106
00:07:21,240 --> 00:07:28,440
blood or gasoline others would probably appreciate the viscerality of these

107
00:07:25,680 --> 00:07:31,560
arguably unpleasant smells still it's pretty hard to imagine a large large

108
00:07:29,759 --> 00:07:34,879
constituency of Resident Evil players who want to smell rotten flesh and

109
00:07:33,080 --> 00:07:41,560
sewage when they're fighting a zombie in Alleyway turn that crap down but

110
00:07:38,599 --> 00:07:45,919
probably the biggest hurdle is simply economic viability it's worth mentioning

111
00:07:43,759 --> 00:07:50,840
that several large VR experiences that places like theme parks have had Al

112
00:07:48,000 --> 00:07:53,720
Factory effects as far back as the 1990s it's just that those effects haven't

113
00:07:52,080 --> 00:07:58,440
been able to make the same jump to viable atome use as VR headsets now we

114
00:07:56,879 --> 00:08:02,879
all know that many gamers are very willing to spend a lot of do on fancy

115
00:08:00,840 --> 00:08:06,919
Niche peripherals but those peripherals still typically have to provide decent

116
00:08:04,639 --> 00:08:10,080
value for the money likewise scent cartridges will need to be relatively

117
00:08:08,319 --> 00:08:14,319
long lasting and relatively cheap to replace or once this thing loses its

118
00:08:12,080 --> 00:08:18,960
novelty just going to be a stinky paper weight it's also hard to see the ability

119
00:08:16,280 --> 00:08:23,280
to smell a game being a better immersion gain than the addition of a VR helmet so

120
00:08:21,039 --> 00:08:28,720
it's very likely to lag far behind VR in adoption even after if it starts to gain

121
00:08:26,520 --> 00:08:32,240
traction still there is an argument to be made that television for all that

122
00:08:30,479 --> 00:08:36,760
it's been a punchline for the last 80 years was just a good idea before its

123
00:08:34,599 --> 00:08:40,760
time even the latest iteration game sense is limited in that it's a third

124
00:08:38,760 --> 00:08:45,160
party trying its best to procedurally match sense to a scene made by other

125
00:08:43,279 --> 00:08:49,200
creators just like those theater owners we mentioned before in an Ideal World

126
00:08:47,600 --> 00:08:53,160
there would be a standard toolbox of sense that creators could work with to

127
00:08:50,959 --> 00:08:57,120
craft a scented experience that matches their create a vision for the content

128
00:08:54,959 --> 00:09:02,399
regardless of which smelly box does the stinking though if YouTube supported it

129
00:09:00,399 --> 00:09:05,440
I'd probably turn off autoplay so thanks for watching guys if you like this video
