00:00:00,080 --> 00:00:08,800
recently i've been getting into streaming vr and there's no doubt that the holy grail vr streaming setup is a

2
00:00:06,319 --> 00:00:12,000
green screen with a mixed reality setup where you actually transport yourself

3
00:00:10,719 --> 00:00:15,920
into the game like we showed off recently only problem is if i wanted to

4
00:00:14,240 --> 00:00:21,680
do something like that in my living room i either have to hack an xbox connect

5
00:00:18,560 --> 00:00:24,480
for a somewhat convincing effect or i

6
00:00:21,680 --> 00:00:29,599
need to paint my living room green which what do you think green living room

7
00:00:26,960 --> 00:00:34,000
yeah i didn't think so so i discovered the next best thing it

8
00:00:31,599 --> 00:00:38,640
turns out that with these these are called vive trackers you can

9
00:00:36,160 --> 00:00:45,360
actually cover your body with additional tracking points that transport you into

10
00:00:41,440 --> 00:00:47,440
the game in avatar form so

11
00:00:45,360 --> 00:00:52,559
hey what can i say i've always dreamed of turning myself into a waifu and now i

12
00:00:50,160 --> 00:00:56,079
can make it a reality this video is brought to you by ridge wallet ridge

13
00:00:54,320 --> 00:00:59,359
wallet wants to redefine the wallet with its compact frame and rfid blocking

Linus where you'll save 10 and get free worldwide shipping

16
00:01:14,080 --> 00:01:18,960
we've got no table so we'll use a monitor box

17
00:01:17,360 --> 00:01:22,080
the vive tracker has already been opened because i've

18
00:01:20,880 --> 00:01:28,320
actually been fighting with this thing for a couple weeks but that's okay the important things in the box are a usb

19
00:01:26,080 --> 00:01:32,560
micro b cable a wall wart which

20
00:01:30,320 --> 00:01:37,680
oh shoot i left them all at the office it's

21
00:01:34,720 --> 00:01:41,280
not a wall wart i knew it i knew at one point that it was not a wall wart and

22
00:01:39,360 --> 00:01:44,560
then for some reason i got it in my head that it was a wall board again okay it

23
00:01:42,640 --> 00:01:49,119
doesn't matter the point is this is a multi-purpose cable purpose number one

24
00:01:47,119 --> 00:01:52,799
is to charge the tracker so this is the tracker it screws on to whatever you

25
00:01:51,040 --> 00:01:56,960
want and allows you to bring outside objects into vr through the same

26
00:01:54,560 --> 00:02:01,040
technology as your controllers and your headset so you charge it up it's got a

27
00:01:58,479 --> 00:02:06,560
battery on board purpose number two is to plug into this little weighted base

28
00:02:03,840 --> 00:02:11,360
that takes right here this little dongle this is the dongle for the tracker that

29
00:02:08,959 --> 00:02:16,720
it needs to communicate its location to your pc now your controllers use the

30
00:02:14,160 --> 00:02:20,800
headset but it only has two connection slots so as soon as you start to add

31
00:02:18,640 --> 00:02:23,520
multiple trackers you run out of connections you could have one

32
00:02:22,160 --> 00:02:27,120
controller and one tracker and you wouldn't need this but as soon as you

33
00:02:25,599 --> 00:02:30,319
want to use both your controllers you're gonna need it let's step back and take a

34
00:02:28,879 --> 00:02:35,200
look at some of the other ways that you can stream vr first though the easiest

35
00:02:32,800 --> 00:02:40,239
is to just import your game as a source into obs this way the audience sees

36
00:02:37,760 --> 00:02:44,400
exactly what you see it's fast it's simple but it does have the disadvantage

37
00:02:42,640 --> 00:02:47,920
of being a little bit disorienting for the audience because they're looking out

38
00:02:46,000 --> 00:02:51,840
through your eyes but they're not in control of where the camera is pointed

39
00:02:50,080 --> 00:02:57,280
you can mitigate this somewhat by widening the field of view and adding a

40
00:02:54,080 --> 00:02:59,040
smooth camera mod but it's not perfect

41
00:02:57,280 --> 00:03:03,120
it's never going to be perfect that's where liv comes in we're going to

42
00:03:00,959 --> 00:03:08,319
get rid of our beat saber source we're going to set our target to beat saber

43
00:03:04,959 --> 00:03:10,400
exe and boom now we've got a virtual

44
00:03:08,319 --> 00:03:14,959
camera that acts as a third-party observer of what the player is doing in

45
00:03:12,640 --> 00:03:18,879
the game now with a green screen we were able to see me standing there in the

46
00:03:16,640 --> 00:03:23,840
game but now this is something different we've got an avatar whose head is

47
00:03:21,760 --> 00:03:27,760
actually moving around according to how i'm holding the headset

48
00:03:25,760 --> 00:03:32,239
makes for a pretty neat experience setting this up is pretty straightforward you look down at your

49
00:03:30,080 --> 00:03:37,200
feet point the little pointer and you are greeted by the camera viewfinder and

50
00:03:34,720 --> 00:03:40,799
avatar menus so camera is basically controlled by saying where

51
00:03:39,040 --> 00:03:45,360
you want the camera to be and where you'd like it to point you've

52
00:03:43,200 --> 00:03:49,519
got third person view which kind of like follows you around i think it's actually

53
00:03:47,519 --> 00:03:52,480
hard to see it because it's following your head around all the time mixed

54
00:03:50,640 --> 00:03:56,000
reality a bunch of different ones i like selfie i just like the automatic angle

55
00:03:54,799 --> 00:04:01,840
you can change your field of view all that kind of good stuff and then there's your avatar you can see mine is pretty

56
00:04:00,239 --> 00:04:05,599
messed up right about now but that's okay we're going to go ahead and

57
00:04:03,519 --> 00:04:10,159
calibrate it stand like this go like that and hey look at that

58
00:04:07,840 --> 00:04:13,120
oh wait except we got a small problem the legs are like

59
00:04:13,280 --> 00:04:19,359
so uh oh wait never mind i did it wrong i did it entirely wrong that time okay

60
00:04:17,759 --> 00:04:23,759
point your little pointer at the icon at your feet my hands and my head are

61
00:04:22,320 --> 00:04:27,759
tracking according to what i'm doing except oh look at that i'm wiggling my

62
00:04:26,000 --> 00:04:32,400
hips and he's just kind of doing whatever that is and if i move

63
00:04:30,080 --> 00:04:36,880
around you can see his legs move in a way that is really unnatural

64
00:04:35,199 --> 00:04:41,520
but in a game like beat saber where you don't necessarily have to move your feet

65
00:04:38,720 --> 00:04:47,120
around much that might not matter to you thing is with my play style i actually

66
00:04:44,639 --> 00:04:51,919
do like to move around a lot because i play this sort of

67
00:04:48,479 --> 00:04:54,639
50 for fun and the other 50 for exercise

68
00:04:51,919 --> 00:04:57,900
so it ends up looking like i'm kind of leaning back and forth looks kind of

69
00:04:56,320 --> 00:05:01,760
stupid

70
00:05:03,120 --> 00:05:09,360
now we're going to add things up a notch one of my free usb ports they are

71
00:05:07,280 --> 00:05:13,199
technically usb2 but if you plug multiples of them into a single hub

72
00:05:11,280 --> 00:05:16,240
people have run into interference or bandwidth issues so your mileage may

73
00:05:14,880 --> 00:05:21,280
vary there one of mine's at the back so i'm going to use this handy dandy extender i'm going to pretend i don't

74
00:05:19,520 --> 00:05:24,320
have these other usb extensions from a previous troubleshooting step and i'm

75
00:05:22,639 --> 00:05:29,680
going to put the other two directly into the front usbs on my case now you may

76
00:05:27,280 --> 00:05:33,680
have some difficulty pairing these controllers i actually had to take

77
00:05:32,320 --> 00:05:37,759
anything but the one i was pairing physically out of the room and just pair

78
00:05:36,000 --> 00:05:40,720
one at a time in order to get them to all pair up properly and then i've gone

79
00:05:39,360 --> 00:05:45,199
i've labeled them all to make sure that i know which one goes with which but your mileage may vary mine are all

80
00:05:43,840 --> 00:05:49,039
paired though so i should be able to just go one two three and they should

81
00:05:47,199 --> 00:05:52,960
fire up for me unless you've got a reliable way to attach your trackers to

82
00:05:50,880 --> 00:05:57,280
your body though your base stations aren't going to know where your body

83
00:05:54,479 --> 00:06:00,639
parts are so that's where this comes in rebuff reality sent this over this is

84
00:05:58,960 --> 00:06:05,680
their track strap plus the only difference between the plus one and the regular one is that it has an integrated

85
00:06:03,520 --> 00:06:10,319
battery bank so you get longer time i would say if you're streaming that long

86
00:06:07,199 --> 00:06:12,800
in vr though you probably don't need to

87
00:06:10,319 --> 00:06:16,720
stream that long in vr at a time you don't want to cut off your circulation

88
00:06:14,160 --> 00:06:20,639
but a tight fit is important because if you're stomping and your trackers are

89
00:06:18,960 --> 00:06:24,080
kind of jiggling around like this it will cause tracking anomalies man this

90
00:06:22,560 --> 00:06:27,919
is some of the nerdiest stuff i've ever done it doesn't get any better from here

91
00:06:26,479 --> 00:06:34,400
because the next thing i'm going to do is roll up my pants a little bit actually to make sure that the pants

92
00:06:32,160 --> 00:06:37,680
don't cover the tracking dots that's one of the reasons you can't just duct tape

93
00:06:35,759 --> 00:06:42,240
these things to your feet because if you cover up too many of the

94
00:06:39,680 --> 00:06:45,520
tracking points then it won't work so yeah we're going flood pants for the

95
00:06:43,520 --> 00:06:48,720
rest of this video with the trackers on my feet we just go into settings

96
00:06:46,800 --> 00:06:52,160
controllers manage vive trackers and make sure that i set the correct roles

97
00:06:50,639 --> 00:06:56,639
for each of them you can see you can actually load yourself up with trackers but we're

98
00:06:54,880 --> 00:07:02,560
going to be going for a relatively modest setup so selfie that's

99
00:06:59,919 --> 00:07:04,800
all good avatar now we're going to add oh yes

100
00:07:03,919 --> 00:07:11,919
feet now that's a little bunged up that's okay we can calibrate that there we go

101
00:07:08,319 --> 00:07:15,120
look at that hand step and step and step

102
00:07:11,919 --> 00:07:15,120
and twirl

103
00:07:15,280 --> 00:07:18,960
there's all kinds of dancing you can do like this

104
00:07:23,680 --> 00:07:31,840
i know so if i was to move back and forth how's

105
00:07:27,759 --> 00:07:31,840
my motion now a little more natural

106
00:07:34,479 --> 00:07:41,120
fine a little weird yeah i mean what's weird about it exactly because i think there's

107
00:07:39,520 --> 00:07:45,520
more than more than one thing that's a little weird right now to achieve a more

108
00:07:43,360 --> 00:07:51,680
convincing level of full body tracking we need just one more tracker this one

109
00:07:49,280 --> 00:07:57,680
is going to go right around the hips because that's really where these joints

110
00:07:54,000 --> 00:07:59,199
move and now we've got full hip wiggle

111
00:07:57,680 --> 00:08:03,919
tracking all right let's have a look at how that works you know you haven't seen enough of this

112
00:08:02,479 --> 00:08:06,080
yeah we're gonna need to recalibrate that

113
00:08:09,120 --> 00:08:17,199
that's where the tracking problems come in and now my butt is up in the air this

114
00:08:14,479 --> 00:08:20,479
was where i was stumped for like two weeks

115
00:08:18,400 --> 00:08:23,840
i tried every combination of ports on the system i tried usb extensions

116
00:08:22,639 --> 00:08:28,960
because i thought it might be a range issue or compatibility issue with the tracker dongles

117
00:08:26,960 --> 00:08:32,080
none of them fix the problem but what i'm hoping

118
00:08:30,800 --> 00:08:35,440
because i really hope we're finishing a video today is that i have the real

119
00:08:34,159 --> 00:08:41,760
solution now in this care package from valve a

120
00:08:38,479 --> 00:08:43,839
typical vr setup has two base stations

121
00:08:41,760 --> 00:08:47,680
you got one on one corner and then you've got one over on the other corner

122
00:08:46,000 --> 00:08:52,320
the problem is that as soon as you've got feet involved and closed and you're

123
00:08:50,399 --> 00:08:56,240
moving around like this or you're you've got your tether coming down the back of

124
00:08:54,080 --> 00:09:00,240
your body it's really easy for the trackers to get occluded from one or

125
00:08:58,640 --> 00:09:05,920
even both of the base stations which is what causes them to drift now i have

126
00:09:02,080 --> 00:09:07,920
particular issues with number c

127
00:09:05,920 --> 00:09:11,760
letter c suggesting that it's not entirely occlusion issues and it could

128
00:09:09,519 --> 00:09:14,080
be a weak radio in here but whatever this

129
00:09:12,560 --> 00:09:19,519
i'm hoping is going to solve it once and for all i'm adding not one but two more

130
00:09:16,640 --> 00:09:24,640
base stations which actually from anecdotal evidence seems to give better

131
00:09:22,000 --> 00:09:28,000
tracking performance just in all cases not just if you're trying to do a full

132
00:09:26,240 --> 00:09:31,200
body setup like what i'm doing i'm not entirely confident this is going to fix

133
00:09:29,760 --> 00:09:34,800
the issue which is why you don't see me drilling any holes in my ceiling just yet

134
00:09:33,680 --> 00:09:38,959
but i am pretty sure

135
00:09:37,920 --> 00:09:41,440
come on stop it

136
00:09:43,040 --> 00:09:48,880
whatever you wanted to replace these floors anyway right wow that's pretty impressive so these

137
00:09:47,279 --> 00:09:52,880
just fired right up looks like one of them needs a firmware update and my

138
00:09:50,640 --> 00:09:57,120
headset my headset got a firmware update while we were working on this this is

139
00:09:54,560 --> 00:10:02,080
compelling youtube content it's moment of truth time now

140
00:09:58,720 --> 00:10:03,279
and my feet are still wandering off into

141
00:10:02,080 --> 00:10:07,839
the sunset okay maybe the answer is a combination

142
00:10:06,800 --> 00:10:15,200
of the two oh that looks way better wow i'm looking through my own waist

143
00:10:12,080 --> 00:10:16,079
shaking it i've got hope no i got rid of

144
00:10:15,200 --> 00:10:20,640
my my saber again

145
00:10:20,640 --> 00:10:26,800
oh no they're drifting what the why are they drifting quite

146
00:10:25,360 --> 00:10:31,279
literally no reason on earth

147
00:10:28,880 --> 00:10:36,160
for this tracker to drift it has three lighthouses

148
00:10:34,160 --> 00:10:40,079
hello what are you doing

149
00:10:37,600 --> 00:10:44,079
there it goes all right see it's here that's where it is

150
00:10:42,800 --> 00:10:48,720
not here here wait why is it up here

151
00:10:49,839 --> 00:10:56,640
new idea sometimes having large reflective surfaces in the room can cause problems

152
00:10:54,880 --> 00:11:01,200
you know that moment when you get a big OLED gaming tv and then you put a

153
00:10:59,200 --> 00:11:05,680
blanket over it to game nope they're all over the place now new

154
00:11:03,440 --> 00:11:08,880
idea and ironically my wife's she was like hey do the antennas have a

155
00:11:07,120 --> 00:11:12,720
particular pickup pattern i was like oh yeah they would be designed to

156
00:11:10,800 --> 00:11:16,560
be plugged in on their little thing probably so she's like oh well why don't

157
00:11:14,880 --> 00:11:21,040
you put them up right well i don't have more of those little bases so how about

158
00:11:18,079 --> 00:11:21,040
this first solution

159
00:11:21,279 --> 00:11:27,920
let's see if that helps good

160
00:11:25,040 --> 00:11:33,839
yeah it's glitching again new idea guys it might be my mic pack

161
00:11:30,399 --> 00:11:33,839
and power that off ouch

162
00:11:35,440 --> 00:11:42,640
are we good wow that actually looks a lot better

163
00:11:39,920 --> 00:11:47,519
fresh day fresh perspective fresh computer i've actually wired up my

164
00:11:45,279 --> 00:11:52,720
test bench with the boot drive from my vr pc let's give it a shot

165
00:11:50,560 --> 00:11:57,440
it seems to be behaving quite a bit better so you can see now as i shift my

166
00:11:55,839 --> 00:12:03,440
hips around in vr we've actually got a fairly

167
00:12:00,560 --> 00:12:08,079
natural style of movement except when the tracker disappears through the floor

168
00:12:05,200 --> 00:12:11,519
which it seems to be doing less of but still doing it which is sort of

169
00:12:09,920 --> 00:12:16,800
unbelievable to me at this point but we're gonna have to call this as good as we can get it for now so let's fulfill

170
00:12:14,720 --> 00:12:21,160
the promise in the title transforming into ninja

171
00:12:18,639 --> 00:12:22,800
chick or whatever this one's called

172
00:12:22,800 --> 00:12:29,120
looking not bad now let's give it a run

173
00:12:27,360 --> 00:12:32,480
does it look alright right now is it working

174
00:12:31,519 --> 00:12:39,680
okay i'm just going to put aside how frustrating the last day

175
00:12:36,880 --> 00:12:43,440
has been and how sleep-deprived i am and i'm just going to play the game

176
00:12:41,839 --> 00:12:47,200
and have fun does it look significantly more natural

177
00:12:45,200 --> 00:12:50,000
than just having the feet i honestly don't remember now

178
00:12:51,440 --> 00:12:57,279
feels like a lifetime ago to me too games are supposed to be fun right then

179
00:12:55,440 --> 00:13:01,440
i'm just gonna have fun now i'm not gonna stress about missing a block or a

180
00:12:59,600 --> 00:13:08,880
little glitch here and there this is supposed to be about documenting fun

181
00:13:05,040 --> 00:13:08,880
see that block i miss right there fun

182
00:13:09,200 --> 00:13:18,120
it's hard to have fun when you're sleep deprived low blood sugar

183
00:13:13,440 --> 00:13:18,120
and so frustrated you can't see strain

184
00:13:20,000 --> 00:13:27,519
yeah i will not rage quit i will rage persevere

185
00:13:24,079 --> 00:13:33,000
dancing to the song that i can barely

186
00:13:27,519 --> 00:13:33,000
hear over the blood pressure in my ears

187
00:13:36,079 --> 00:13:42,079
oh i don't know if i can say that that's worth it

188
00:13:40,399 --> 00:13:47,600
but uh i don't know does at least look kind of cool until i check the headset onto the

189
00:13:45,920 --> 00:13:49,640
couch and it looks like i dive bombed it you know i feel like dive bombing into

190
00:13:49,120 --> 00:13:54,429
the couch

191
00:13:55,040 --> 00:14:02,959
guys i think that it's fixed check this out

192
00:14:00,639 --> 00:14:02,959
ah

193
00:14:06,880 --> 00:14:13,680
that looks really good doesn't it still getting a little bit of glitchiness but

194
00:14:10,800 --> 00:14:18,639
what i did was i changed over to a four port usb card that has a separate

195
00:14:16,000 --> 00:14:23,040
controller for every single port and it looks like after all that the issue

196
00:14:20,959 --> 00:14:28,639
really was some kind of usb incompatibility so i got the diagnosis

197
00:14:25,600 --> 00:14:31,600
right but then i solved the problem

198
00:14:28,639 --> 00:14:36,160
incorrectly is that does it look good like it seems pretty good oh i wondered

199
00:14:33,760 --> 00:14:39,680
i wandered forward a little bit okay and this whole experience is brought to
