The maxim, "Know thyself"
0
0
2000
00:17
has been around since the ancient Greeks.
1
2000
2000
00:19
Some attribute this golden world knowledge to Plato,
2
4000
3000
00:22
others to Pythagoras.
3
7000
2000
00:24
But the truth is it doesn't really matter which sage said it first,
4
9000
3000
00:27
because it's still sage advice, even today.
5
12000
3000
00:31
"Know thyself."
6
16000
2000
00:33
It's pithy
7
18000
2000
00:35
almost to the point of being meaningless,
8
20000
2000
00:37
but it rings familiar and true, doesn't it?
9
22000
3000
00:40
"Know thyself."
10
25000
3000
00:43
I understand this timeless dictum
11
28000
2000
00:45
as a statement about the problems, or more exactly the confusions,
12
30000
3000
00:48
of consciousness.
13
33000
2000
00:50
I've always been fascinated with knowing the self.
14
35000
2000
00:52
This fascination led me to submerge myself in art,
15
37000
2000
00:54
study neuroscience
16
39000
2000
00:56
and later to become a psychotherapist.
17
41000
2000
00:58
Today I combine all my passions
18
43000
2000
01:00
as the CEO of InteraXon,
19
45000
2000
01:02
a thought-controlled computing company.
20
47000
2000
01:04
My goal, quite simply,
21
49000
2000
01:06
is to help people become more in tune
22
51000
2000
01:08
with themselves.
23
53000
2000
01:10
I take it from this little dictum,
24
55000
2000
01:12
"Know thyself."
25
57000
2000
01:14
If you think about it,
26
59000
2000
01:16
this imperative is kind of the defining characteristic of our species,
27
61000
2000
01:18
isn't it?
28
63000
2000
01:20
I mean, it's self-awareness
29
65000
2000
01:22
that separates Homo sapiens
30
67000
2000
01:24
from earlier instances of our mankind.
31
69000
3000
01:27
Today we're often too busy
32
72000
2000
01:29
tending to our iPhones and iPods
33
74000
2000
01:31
to really stop and get to know ourselves.
34
76000
3000
01:34
Under the deluge of minute-to-minute text conversations,
35
79000
3000
01:37
emails, relentless exchange of media channels
36
82000
3000
01:40
and passwords and apps and reminders and Tweets and tags,
37
85000
3000
01:43
we lose sight of what all this fuss is supposed to be about in the first place:
38
88000
3000
01:46
ourselves.
39
91000
2000
01:48
Much of the time we're transfixed
40
93000
2000
01:50
by all of the ways we can reflect ourselves into the world.
41
95000
4000
01:54
And we can barely find the time to reflect deeply
42
99000
3000
01:57
back in on our own selves.
43
102000
3000
02:00
We've cluttered ourselves up with all this.
44
105000
2000
02:02
And we feel like we have to get
45
107000
2000
02:04
far, far away to a secluded retreat, leaving it all behind.
46
109000
3000
02:07
So we go far away
47
112000
2000
02:09
to the top of a mountain,
48
114000
2000
02:11
assuming that perching ourselves on a piece
49
116000
2000
02:13
is bound to give us the respite we need
50
118000
2000
02:15
to sort the clutter, the chaotic everyday,
51
120000
2000
02:17
and find ourselves again.
52
122000
2000
02:19
But on that mountain
53
124000
2000
02:21
where we gain that beautiful peace of mind,
54
126000
3000
02:24
what are we really achieving?
55
129000
3000
02:27
It's really only a successful escape.
56
132000
3000
02:30
Think of the term we use, "Retreat."
57
135000
2000
02:32
This is the term that armies use when they've lost a battle.
58
137000
3000
02:35
It means we've got to get out of here.
59
140000
2000
02:37
Is this how we feel about the pressures of our world,
60
142000
2000
02:39
that in order to get inside ourselves,
61
144000
2000
02:41
you have to run for the hills?
62
146000
3000
02:44
And the problem with escaping your day-to-day life
63
149000
3000
02:47
is that you have to come home eventually.
64
152000
3000
02:50
So when you think about it,
65
155000
2000
02:52
we're almost like a tourist
66
157000
2000
02:54
visiting ourselves over there.
67
159000
3000
02:57
And eventually that vacation's got to come to an end.
68
162000
3000
03:00
So my question to you is,
69
165000
3000
03:03
can we find ways to know ourselves
70
168000
2000
03:05
without the escape?
71
170000
2000
03:07
Can we redefine our relationship
72
172000
2000
03:09
with the technologized world
73
174000
2000
03:11
in order to have the heightened sense of self-awareness
74
176000
2000
03:13
that we seek?
75
178000
2000
03:15
Can we live here and now in our wired web
76
180000
3000
03:18
and still follow those ancient instructions,
77
183000
3000
03:21
"Know thyself?"
78
186000
3000
03:24
I say the answer is yes.
79
189000
2000
03:26
And I'm here today to share a new way
80
191000
2000
03:28
that we're working with technology to this end
81
193000
2000
03:30
to get familiar with our inner self
82
195000
2000
03:32
like never before --
83
197000
2000
03:34
humanizing technology
84
199000
2000
03:36
and furthering that age-old quest of ours
85
201000
2000
03:38
to more fully know the self.
86
203000
3000
03:41
It's called thought-controlled computing.
87
206000
4000
03:47
You may or may not have noticed
88
212000
2000
03:49
that I'm wearing a tiny electrode on my forehead.
89
214000
2000
03:51
This is actually a brainwave sensor
90
216000
2000
03:53
that's reading the electrical activity of my brain
91
218000
2000
03:55
as I give this talk.
92
220000
2000
03:57
These brainwaves are being analyzed and we can see them as a graph.
93
222000
3000
04:00
Let me show you what it looks like.
94
225000
3000
04:03
That blue line there is my brainwave.
95
228000
3000
04:06
It's the direct signal being recorded from my head,
96
231000
2000
04:08
rendered in real time.
97
233000
2000
04:10
The green and red bars show that same signal displayed by frequency,
98
235000
3000
04:13
with lower frequencies here
99
238000
2000
04:15
and higher frequencies up here.
100
240000
2000
04:17
You're actually looking inside my head as I speak.
101
242000
3000
04:22
These graphs are compelling, they're undulating,
102
247000
3000
04:25
but from a human's perspective,
103
250000
2000
04:27
they're actually not very useful.
104
252000
2000
04:29
That's why we've spent a lot of time
105
254000
2000
04:31
thinking about how to make this data meaningful
106
256000
2000
04:33
to the people who use it.
107
258000
2000
04:35
For instance, what if I could use this data
108
260000
3000
04:38
to find out how relaxed I am at any moment?
109
263000
2000
04:40
Or what if I can take that information
110
265000
2000
04:42
and put it into an organic shape up on the screen?
111
267000
3000
04:45
The shape on the right over here
112
270000
3000
04:48
has become an indicator of what's going on in my head.
113
273000
2000
04:50
The more relaxed I am,
114
275000
2000
04:52
the more the energy's going to fall through it.
115
277000
2000
04:54
I may also be interested in knowing
116
279000
2000
04:56
how focused I am,
117
281000
2000
04:58
so I can put my level of attention into the circuit board on the other side.
118
283000
3000
05:01
And the more focused my brain is,
119
286000
2000
05:03
the more the circuit board is going to surge with energy.
120
288000
3000
05:06
Ordinarily, I would have no way of knowing how focused or relaxed I was
121
291000
3000
05:09
in any tangible way.
122
294000
3000
05:12
As we know, our feelings about how we're feeling
123
297000
2000
05:14
are notoriously unreliable.
124
299000
2000
05:16
We've all had stress creep up on us without even noticing it
125
301000
3000
05:19
until we lost it on someone who didn't deserve it,
126
304000
2000
05:21
and then we realize that we probably should have checked in with ourselves
127
306000
3000
05:24
a little earlier.
128
309000
2000
05:26
This new awareness
129
311000
2000
05:28
opens up vast possibilities
130
313000
2000
05:30
for applications that help improve our lives and ourselves.
131
315000
3000
05:33
We're trying to create technology that uses the insights
132
318000
3000
05:36
to make our work more efficient, our breaks more relaxing
133
321000
3000
05:39
and our connections deeper and more fulfilling than ever.
134
324000
3000
05:43
I'm going to share some of these visions with you in a bit,
135
328000
3000
05:46
but first I want to take a look at how we got here.
136
331000
3000
05:49
By the way, feel free to check in on my head at any time.
137
334000
3000
05:52
(Laughter)
138
337000
2000
05:54
My team at InteraXon and I
139
339000
2000
05:56
have been developing throught-controlled application for almost a decade now.
140
341000
3000
05:59
In the first phase of development
141
344000
2000
06:01
we were really enthused by all the things we could control with our mind.
142
346000
3000
06:04
We were making things activate, light up and work
143
349000
3000
06:07
just by thinking.
144
352000
2000
06:09
We were transcending the space
145
354000
2000
06:11
between the mind and the device.
146
356000
2000
06:13
We brought to life a vast array of prototypes and products
147
358000
3000
06:16
that you could control with your mind,
148
361000
2000
06:18
like thought-controlled home appliances
149
363000
2000
06:20
or slot car games or video games
150
365000
2000
06:22
or a levitating chair.
151
367000
2000
06:24
We created technology and applications
152
369000
2000
06:26
that engaged people's imaginations,
153
371000
2000
06:28
and it was really exciting.
154
373000
2000
06:30
And then we were asked to do something really big
155
375000
2000
06:32
for the Olympics.
156
377000
2000
06:34
We were invited to create a massive installation
157
379000
2000
06:36
at the Vancouver 2010 winter Olympics,
158
381000
2000
06:38
were used in Vancouver,
159
383000
2000
06:40
got to control the lighting on the C.N. Tower,
160
385000
2000
06:42
the Canadian Parliament buildings and Niagara Falls
161
387000
3000
06:45
from all the way across the country
162
390000
3000
06:48
using their minds.
163
393000
2000
06:50
Over 17 days at the Olympics 7,000 visitors from all over the world
164
395000
3000
06:53
actually got to individually control the light
165
398000
2000
06:55
from the C.N. Tower, parliament and Niagara in real time
166
400000
2000
06:57
with their minds from across the country,
167
402000
2000
06:59
3,000 km away.
168
404000
2000
07:01
So controlling stuff with your mind
169
406000
2000
07:03
is pretty cool.
170
408000
2000
07:05
But we're always interested in multi-tiered levels of human interaction.
171
410000
3000
07:08
And so we began looking into inventing
172
413000
2000
07:10
thought-controlled applications
173
415000
2000
07:12
in a more complex frame than just control.
174
417000
3000
07:15
And that was responsiveness.
175
420000
3000
07:18
We realized that we had a system
176
423000
2000
07:20
that allowed technology to know something about you.
177
425000
2000
07:22
And it could join into the relationship with you.
178
427000
4000
07:26
We created the responsive room
179
431000
2000
07:28
where the lights music and blinds adjusted to your state.
180
433000
3000
07:31
They followed these little shifts in your mental activity.
181
436000
3000
07:34
So as you settled into relaxation at the end of a hard day,
182
439000
2000
07:36
on the couch in our office,
183
441000
2000
07:38
the music would mellow with you.
184
443000
3000
07:41
When you read, the desk lamp would get brighter.
185
446000
2000
07:43
If you nod off, the system would know,
186
448000
3000
07:46
dimming to darkness as you do.
187
451000
3000
07:49
We then realized that if technology could know something about you
188
454000
3000
07:52
and use it to help you,
189
457000
2000
07:54
there's an even more valuable application than that.
190
459000
3000
07:57
That you could know something about yourself.
191
462000
3000
08:00
We could know sides of ourselves
192
465000
2000
08:02
that were all but invisible
193
467000
2000
08:04
and come to see things that were previously hidden.
194
469000
3000
08:07
Let me show you an example of what I'm talking about here.
195
472000
2000
08:09
Here's an application
196
474000
2000
08:11
that I created for the iPad.
197
476000
2000
08:13
So the goal of the original game Zen Bound
198
478000
2000
08:15
is to wrap a rope around a wooden form.
199
480000
2000
08:17
So you use it with your headset.
200
482000
2000
08:19
The headset connects wirelessly to an iPad or a smartphone.
201
484000
3000
08:22
In that headset
202
487000
2000
08:24
you have fabric sensors on your forehead and above the ear.
203
489000
3000
08:27
In the original Zen Bound game,
204
492000
2000
08:29
you play it by scrolling your fingers over the pad.
205
494000
3000
08:32
In the game that we created, of course,
206
497000
2000
08:34
you control the wooden form that's on the screen there
207
499000
2000
08:36
with your mind.
208
501000
2000
08:38
As you focus on the wooden form,
209
503000
2000
08:40
it rotates.
210
505000
2000
08:42
The more you focus, the faster the rotation.
211
507000
3000
08:45
This is for real.
212
510000
2000
08:47
This is not a fake.
213
512000
2000
08:49
What's really interesting to me though
214
514000
2000
08:51
is at the end of the game you get stats and feedback
215
516000
2000
08:53
about how you did.
216
518000
2000
08:55
You have graphs and charts
217
520000
2000
08:57
that tell you how your brain was doing --
218
522000
2000
08:59
not just how much rope you used or what your high score is,
219
524000
3000
09:02
but what was going on
220
527000
2000
09:04
inside of your mind.
221
529000
2000
09:06
And this is valuable feedback
222
531000
2000
09:08
that we can use to understand what's going on
223
533000
3000
09:11
inside of ourselves.
224
536000
3000
09:14
I like to call this
225
539000
2000
09:16
"intra-active."
226
541000
2000
09:18
Normally we think about technology
227
543000
2000
09:20
as interactive.
228
545000
2000
09:22
This technology
229
547000
2000
09:24
is intra-active.
230
549000
2000
09:26
It understands what's inside of you
231
551000
3000
09:29
and builds a sort of responsive relationship
232
554000
3000
09:32
between you and your technology
233
557000
2000
09:34
so that you can use this information
234
559000
2000
09:36
to move you forward.
235
561000
2000
09:38
So you can use this information
236
563000
2000
09:40
to understand you in a responsive loop.
237
565000
3000
09:43
At InteraXon,
238
568000
4000
09:47
intra-active technology
239
572000
3000
09:50
is one of our really defining mandates.
240
575000
3000
09:53
It's how we understand the world inside
241
578000
3000
09:56
and reflect it outside
242
581000
2000
09:58
into this tight loop.
243
583000
3000
10:01
For example, thought-controlled computing
244
586000
3000
10:04
can teach children with ADD
245
589000
2000
10:06
how to improve their focus.
246
591000
2000
10:08
With ADD, children have a low proportion of beta waves for focus states
247
593000
4000
10:12
and a high proportion of theta states.
248
597000
2000
10:14
So you can create applications that reward focused brain states.
249
599000
3000
10:17
So you can imagine kids playing video games with their brain waves
250
602000
3000
10:20
and improving their ADD symptoms as they do it.
251
605000
3000
10:23
This can be as effective as Ritalin.
252
608000
3000
10:26
Perhaps even more importantly,
253
611000
2000
10:28
thought-controlled computing can give children with ADD
254
613000
2000
10:30
insights into their own fluctuating mental states,
255
615000
3000
10:33
so they can better understand themselves
256
618000
2000
10:35
and their learning needs.
257
620000
2000
10:37
The way these children will be able to use their new awareness to improve themselves
258
622000
4000
10:41
will upend many of the damaging and widespread social stigmas
259
626000
3000
10:44
that people who are diagnosed as different
260
629000
2000
10:46
are challenged with.
261
631000
2000
10:48
We can peer inside our heads
262
633000
2000
10:50
and interact with what was once locked away from us,
263
635000
2000
10:52
what once mystified and separated us.
264
637000
5000
10:57
Brainwave technology can understand us, anticipate our emotions
265
642000
3000
11:00
and find the best solutions for our needs.
266
645000
2000
11:02
Imagine this collected awareness of the individual
267
647000
3000
11:05
computed and reflected across an entire lifespan.
268
650000
3000
11:08
Imagine the insights that you can gain
269
653000
2000
11:10
from this kind of second sight.
270
655000
2000
11:12
It would be like plugging into your own personal Google.
271
657000
3000
11:15
On the subject of Google,
272
660000
2000
11:17
today you can search and tag images
273
662000
2000
11:19
based on the thoughts and feelings you had while you watched them.
274
664000
3000
11:22
You can tag pictures of baby animals as happy,
275
667000
2000
11:24
or whatever baby animals are to you,
276
669000
3000
11:27
and then you can search that database,
277
672000
2000
11:29
navigating with your feelings,
278
674000
2000
11:31
rather than the keywords that just hint at them.
279
676000
3000
11:34
Or you could tag Facebook photos
280
679000
2000
11:36
with the emotions that you had associated
281
681000
3000
11:39
with those memories
282
684000
2000
11:41
and then instantly prioritize
283
686000
2000
11:43
the streams that catch your attention,
284
688000
2000
11:45
just like this.
285
690000
3000
11:48
Humanizing technology
286
693000
2000
11:50
is about taking what's already natural about the human-tech experience
287
695000
3000
11:53
and building technology seamlessly in tandem with it.
288
698000
3000
11:56
As it aligns with our human behaviors,
289
701000
2000
11:58
it can allow us to make better sense of what we do
290
703000
3000
12:01
and, more importantly, why,
291
706000
3000
12:04
creating a big picture
292
709000
2000
12:06
out of all the important little details
293
711000
2000
12:08
that make up who we are.
294
713000
2000
12:10
With humanized technology
295
715000
2000
12:12
we can monitor the quality of your sleep cycles.
296
717000
2000
12:14
When our productivity starts to slacken,
297
719000
3000
12:17
we can go back to that data
298
722000
2000
12:19
and see how we can make more effective balance
299
724000
2000
12:21
between work and play.
300
726000
2000
12:23
Do you know what causes fatigue in you
301
728000
2000
12:25
or what brings out your energetic self,
302
730000
2000
12:27
what triggers cause you to be depressed
303
732000
3000
12:30
or what fun things are going to bring you out of that funk?
304
735000
4000
12:34
Imagine if you had access to data
305
739000
2000
12:36
that allowed you to rank on a scale of overall happiness
306
741000
3000
12:39
which people in your life made you the happiest,
307
744000
3000
12:42
or what activities brought you joy.
308
747000
3000
12:45
Would you make more time for those people? Would you prioritize?
309
750000
3000
12:48
Would you get a divorce?
310
753000
3000
12:51
What thought-controlled computing can allow you to do
311
756000
2000
12:53
is build colorful layered pictures of our lives.
312
758000
3000
12:56
And with this, we can get the skinny on our psychological happenings
313
761000
3000
12:59
and build a story of our behaviors over time.
314
764000
3000
13:02
We can begin to see the underlying narratives
315
767000
2000
13:04
that propel us forward
316
769000
2000
13:06
and tell us about what's going on.
317
771000
3000
13:09
And from this,
318
774000
2000
13:11
we can learn how to change the plot, the outcome
319
776000
2000
13:13
and the character
320
778000
2000
13:15
of our personal stories.
321
780000
2000
13:17
Two millennia ago,
322
782000
2000
13:19
those Greeks had some powerful insights.
323
784000
3000
13:22
They knew that a fundamental piece falls into place
324
787000
3000
13:25
when you start to live out their little phrase,
325
790000
3000
13:28
when you come into contact with yourself.
326
793000
3000
13:31
They understood the power of human narrative
327
796000
3000
13:34
and the value that we place on humans
328
799000
2000
13:36
as changing, evolving and growing.
329
801000
3000
13:39
But they understood something more fundamental --
330
804000
3000
13:42
the sheer joy in discovery,
331
807000
3000
13:45
the delight and fascination that we get from the world
332
810000
3000
13:48
and being ourselves in it,
333
813000
2000
13:50
the richness that we get
334
815000
2000
13:52
from seeing, feeling and knowing the lives that we are.
335
817000
3000
13:55
My mom's an artist,
336
820000
2000
13:57
and as a child I'd often see her bring things to life with the stroke of a brush.
337
822000
3000
14:00
One moment it was all white space, pure possibility.
338
825000
3000
14:03
The next, it was alive
339
828000
2000
14:05
with her colorful ideas and expressions.
340
830000
3000
14:08
As I sat easel-side,
341
833000
2000
14:10
watching her transform canvas after canvas,
342
835000
3000
14:13
I learned that you could create your own world.
343
838000
4000
14:17
I learned that our own inner worlds --
344
842000
2000
14:19
our ideas, emotions and imaginations --
345
844000
3000
14:22
were, in fact, not bound by our brains and bodies.
346
847000
4000
14:26
If you could think it, if you could discover it,
347
851000
3000
14:29
you could bring it to life.
348
854000
3000
14:32
To me, thought-controlled computing
349
857000
2000
14:34
is as simple and powerful as a paintbrush --
350
859000
2000
14:36
one more tool to unlock and enliven
351
861000
3000
14:39
the hidden worlds within us.
352
864000
2000
14:41
I look forward to the day
353
866000
2000
14:43
that I can sit beside you, easel-side,
354
868000
3000
14:46
watching the world that we can create
355
871000
2000
14:48
with our new toolboxes
356
873000
2000
14:50
and the discoveries that we can make
357
875000
2000
14:52
about ourselves.
358
877000
2000
14:54
Thank you.
359
879000
2000
14:56
