1
00:00:00,080 --> 00:00:06,480
how would you play games on your pc if you couldn't use your hands

2
00:00:04,080 --> 00:00:10,240
your first instinct might be to use your feet uh maybe even with a foot

3
00:00:08,400 --> 00:00:14,719
controller like the beacon or the stinky footboard but then what if you couldn't use your

4
00:00:12,719 --> 00:00:20,160
feet either in that case you might be tempted to get more uh creative

5
00:00:17,840 --> 00:00:24,800
but fortunately for the many people out there including many gamers who struggle

6
00:00:22,720 --> 00:00:31,320
to use a conventional keyboard or mouse there's another option introducing quad

7
00:00:27,279 --> 00:00:31,320
joy a mouse you control

8
00:00:31,599 --> 00:00:38,480
with your mouth speaking of mouth my mouth saying these

9
00:00:36,000 --> 00:00:41,840
words about our sponsor kono kono is excited to introduce the hex gears x1

10
00:00:40,480 --> 00:00:45,200
keyboard a low profile bluetooth mechanical keyboard with multi-device

11
00:00:43,680 --> 00:00:49,000
connectivity in a beautifully machined aluminum case check out the link below

12
00:00:47,120 --> 00:00:53,969
to learn more

13
00:00:57,199 --> 00:01:04,720
so how do you control a mouse with your mouth well the first step is to actually

14
00:01:02,399 --> 00:01:10,560
get this device close enough to your face which quad joy accomplishes with

15
00:01:07,760 --> 00:01:14,400
a clamp and a mounting ARM now there are two styles of clamps available and this

16
00:01:12,880 --> 00:01:19,040
is the most popular one there's also this like kind of pipe mounting clamp

17
00:01:16,960 --> 00:01:24,159
one which can grab on to pretty much anything so it's better for wheelchairs

18
00:01:21,360 --> 00:01:28,479
but it's almost three times the price and both of them can connect to the

19
00:01:25,840 --> 00:01:32,560
mounting ARM in multiple orientations so this one this little bit unscrews and

20
00:01:30,240 --> 00:01:36,880
you can put it on any one of these five mounting points and then this one

21
00:01:34,960 --> 00:01:41,360
you either put it on sideways and mount it here or here or here or you put it on

22
00:01:39,520 --> 00:01:46,159
this way and mount it up here that's what we're going to be doing then you

23
00:01:43,520 --> 00:01:51,680
got your mounting ARM this thing is heavy duty af like it's sturdy enough to

24
00:01:50,240 --> 00:01:57,680
keep the device in place and air like look i'm waving it around and it's not

25
00:01:54,399 --> 00:01:59,680
bending but it's also flexible enough

26
00:01:57,680 --> 00:02:03,759
that you can tailor it to your exact setup and it'll stay exactly where you

27
00:02:01,520 --> 00:02:08,640
want it's also got this really nice articulating end here that again really

28
00:02:06,079 --> 00:02:12,560
nice quality you just loosen up configure however you want it tighten it

29
00:02:10,959 --> 00:02:16,319
up with just one knob and boom

30
00:02:14,400 --> 00:02:23,560
this gives you the precision you need to get the quad joy to your lips please

31
00:02:18,640 --> 00:02:23,560
stand by while Linus installs the device

32
00:02:29,840 --> 00:02:36,560
so the mouse itself is basically

33
00:02:34,800 --> 00:02:41,200
a single joystick so you can probably see the cursor moving around

34
00:02:38,400 --> 00:02:46,160
but with the added ability to respond to your breath so out of the box it's

35
00:02:44,239 --> 00:02:50,720
totally plug and play with no software required and the basic i don't know i

36
00:02:48,480 --> 00:02:55,760
guess you could call them like gestures that it's pre-programmed with or a sip

37
00:02:53,360 --> 00:02:59,680
for left click or a puff for right click

38
00:03:00,959 --> 00:03:08,480
cool right now there is a learning curve so to get to

39
00:03:06,400 --> 00:03:14,080
the same level that i would have with my hands would take tens if not hundreds of

40
00:03:11,519 --> 00:03:18,159
hours but the folks at quad joy have done their best to make it as easy as

41
00:03:15,920 --> 00:03:22,560
possible first of all there are led indicators that you can actually see out

42
00:03:20,400 --> 00:03:26,400
of your peripheral vision so it's easy to tell for example when you've entered

43
00:03:24,319 --> 00:03:29,280
what they call scrolling mode all you've got to do is puff

44
00:03:29,599 --> 00:03:36,640
until this indicator turns green and then you can puff and sip in order to

45
00:03:34,480 --> 00:03:40,000
scroll up and down a page pretty cool

46
00:03:37,840 --> 00:03:44,400
and there's the totally optional quad joy desktop app that lets you take these

47
00:03:42,400 --> 00:03:48,640
default actions and greatly expand them you can do a ton of

48
00:03:46,400 --> 00:03:54,159
tweaking to everything from how the stick behaves to pointer speed and

49
00:03:51,440 --> 00:03:57,760
acceleration to even the required breath force it's actually pretty deep and the

50
00:03:55,840 --> 00:04:04,560
best part is the amount of customization that they give you with the gestures

51
00:03:59,280 --> 00:04:06,720
with just sipping and puffing so like

52
00:04:04,560 --> 00:04:10,640
you can program up to 12 different actions with basically whatever key

53
00:04:08,799 --> 00:04:16,000
binding you want so so you could you know puff soft then hard for ctrl alt

54
00:04:13,439 --> 00:04:20,479
delete or to launch the calculator or whatever the case may be it's awesome

55
00:04:18,000 --> 00:04:23,520
but wait there's more actually a lot more

56
00:04:21,359 --> 00:04:28,479
so you can execute functions with multiple types of gestures

57
00:04:25,840 --> 00:04:33,360
not just sipping and puffing like by moving the stick to the edge and holding

58
00:04:30,160 --> 00:04:33,360
for example check this out

59
00:04:36,000 --> 00:04:42,479
there it is and you can actually create

60
00:04:39,280 --> 00:04:46,320
a gesture to switch modes giving you a

61
00:04:42,479 --> 00:04:48,880
whole other layer of commands on the fly

62
00:04:46,320 --> 00:04:53,280
using those same sips and puffs or hold stick to edges and then what's cool is

63
00:04:50,960 --> 00:04:57,040
you can import and export your settings so you can optimize the mouse or the

64
00:04:55,120 --> 00:05:01,680
quad joy as it were for different applications on your computer leading us

65
00:04:59,120 --> 00:05:07,880
of course then to the question with all this customization can you game on it

66
00:05:19,280 --> 00:05:26,400
did i help you

67
00:05:23,280 --> 00:05:26,400
we're really in the net

68
00:05:28,080 --> 00:05:33,680
all right so believe it or not it depends on the

69
00:05:31,919 --> 00:05:37,840
game you can actually play something like rocket league with near full

70
00:05:35,680 --> 00:05:43,440
functionality since all you need is movement with the stick and then boost

71
00:05:40,320 --> 00:05:44,960
and jump can be done with your breaths

72
00:05:43,440 --> 00:05:51,280
pretty cool right and even mouse-centric games like rts

73
00:05:48,160 --> 00:05:52,639
rpg or board games were shockingly

74
00:05:51,280 --> 00:05:57,120
functional now the tricky genre is FPS

75
00:05:56,000 --> 00:06:03,039
so can it run crisis

76
00:06:00,479 --> 00:06:07,120
okay technically this isn't crisis but whatever the same principles apply now

77
00:06:05,280 --> 00:06:11,199
to do this properly you'd really want two joysticks one for looking around

78
00:06:11,440 --> 00:06:17,280
and then one for moving and we couldn't find an effective way to do both of

79
00:06:16,000 --> 00:06:22,080
those things at the same time on the quad joy so the best we managed was

80
00:06:19,360 --> 00:06:26,080
using the stick to look and then just inhaling to move forward and then

81
00:06:24,560 --> 00:06:29,680
puffing to shoot now it technically works but it's a pretty bad time

82
00:06:32,080 --> 00:06:37,600
but what if you used the stick to run around

83
00:06:35,840 --> 00:06:41,919
then stopped switched mouse modes to look around a

84
00:06:39,680 --> 00:06:44,800
name and shoot and then switch back to keep moving

85
00:06:43,039 --> 00:06:49,199
that's basically what twitch dreamer rocky no hands does

86
00:06:46,880 --> 00:06:54,400
and odds are he can absolutely pwn you at fortnight however he uses a different

87
00:06:51,600 --> 00:06:59,199
controller the quad stick so would this approach work on the quad joy

88
00:06:57,840 --> 00:07:04,639
unfortunately no because the software doesn't let you

89
00:07:01,520 --> 00:07:07,440
bind stick movements to key presses like

90
00:07:04,639 --> 00:07:13,520
up equals w what they do offer is a sold separately

91
00:07:10,240 --> 00:07:15,520
210 dollar feature called joystick mode

92
00:07:13,520 --> 00:07:19,759
that we actually ended up needing third-party software called joy to key

93
00:07:18,240 --> 00:07:22,639
to fully utilize it does allow you to move around using

94
00:07:21,280 --> 00:07:27,120
the stick oh dang it

95
00:07:24,800 --> 00:07:30,560
but it creates a new problem so they don't actually let you do gestures in

96
00:07:29,280 --> 00:07:36,080
joystick mode so you have no way to quickly switch

97
00:07:33,759 --> 00:07:40,000
back to mouse mode when you're done moving around

98
00:07:37,599 --> 00:07:42,319
and it's time to aim and fire at something

99
00:07:43,680 --> 00:07:49,440
all right then so assuming you're in the market for a mouth mouse should you buy

100
00:07:47,759 --> 00:07:55,120
the quad joy uh if you're a gamer well it's clearly

101
00:07:51,840 --> 00:07:57,199
not designed with gaming in mind but for

102
00:07:55,120 --> 00:08:02,560
general computer use there are really a lot of great things about it

103
00:07:59,840 --> 00:08:07,759
that are hampered by a couple of complaints one

104
00:08:04,560 --> 00:08:09,120
the amount of play on the mounting ARM

105
00:08:07,759 --> 00:08:13,840
is in our minds unacceptable for something that costs

106
00:08:12,319 --> 00:08:18,479
complaint number two this much

107
00:08:15,520 --> 00:08:24,879
this wiggle in the mount right down here amounts to a significant dead zone in

108
00:08:21,199 --> 00:08:27,360
either the x or the y-axis depending on

109
00:08:24,879 --> 00:08:31,520
which way you mount it and at fourteen hundred dollars

110
00:08:28,960 --> 00:08:36,080
quad joy costs about double what the quad stick does and that one has been

111
00:08:34,399 --> 00:08:39,440
proven to be performance enough for competitive gaming and with multiple

112
00:08:38,080 --> 00:08:43,440
mouth options so i don't see why you might not start

113
00:08:41,919 --> 00:08:47,760
there instead though to be clear we haven't tested

114
00:08:46,320 --> 00:08:51,839
any of the other products in the market and we're not really the target consumer

115
00:08:49,839 --> 00:08:56,160
for these products anyway the purpose of this video for us was to experience a

116
00:08:54,240 --> 00:09:00,000
type of mouse input that we had never tried before and draw attention to a

117
00:08:58,880 --> 00:09:03,839
segment of the market that really doesn't get talked about much so if you

118
00:09:02,080 --> 00:09:07,279
have experience with either of the products we've talked about or maybe

119
00:09:05,279 --> 00:09:11,279
another one we didn't cover please leave a message in the comments section below

120
00:09:11,519 --> 00:09:17,440
speaking of below below we're going to have a link to brilliant

121
00:09:15,920 --> 00:09:22,000
brilliant believes that effective learning is active not passive and

122
00:09:19,600 --> 00:09:26,399
learning from lectures and videos isn't as effective as diving in and doing

123
00:09:24,480 --> 00:09:30,160
things for yourself and brilliant provides you with the framework for

124
00:09:28,080 --> 00:09:34,399
thinking about and solving problems so it's kind of like a problem-solving

125
00:09:31,760 --> 00:09:39,120
website that teaches you to think like a computer scientist by guiding you

126
00:09:36,399 --> 00:09:43,519
through problems so they take a concept break it up into bite-sized pieces

127
00:09:41,360 --> 00:09:47,600
present clear thinking in each part and then build back up to an interesting

128
00:09:45,200 --> 00:09:52,720
conclusion so head over to brilliant.org forward slash Linus tech tips and get 20

129
00:09:50,640 --> 00:09:55,360
off today we're gonna have that linked below
