Two-thirds of the world may not have access to the latest smartphone, but local electronic shops are adept at fixing older tech using low-cost parts. Vinay Venkatraman explains his work in "technology crafts," through which a mobile phone, a lunchbox and a flashlight can become a digital projector for a village school, or an alarm clock and a mouse can be melded into a medical device for local triage.

Frugal Digital is essentially a small research group at C.I.D.
0
502
5285
00:17
where we are looking to find
1
5787
2143
00:19
alternate visions of how to create a digitally inclusive society.
2
7930
4540
00:24
That's what we're after.
3
12470
1808
00:26
And we do this because we actually believe
4
14278
2180
00:28
that silicon technology today is mostly about
5
16458
3274
00:31
a culture of excess.
6
19732
1752
00:33
It's about the fastest and the most efficient
7
21484
2173
00:35
and the most dazzling gadget you can have,
8
23657
2430
00:38
while about two-thirds of the world
9
26087
2898
00:40
can hardly reach the most basic of this technology
10
28985
3684
00:44
to even address fundamental needs in life,
11
32669
3583
00:48
including health care, education
12
36252
2168
00:50
and all these kinds of very fundamental issues.
13
38420
4079
00:54
So before I start, I want to talk about a little anecdote,
14
42499
3245
00:57
a little story about a man I met once in Mumbai.
15
45744
4023
01:01
So this man, his name is Sathi Shri.
16
49767
2187
01:03
He is an outstanding person,
17
51954
2106
01:06
because he's a small entrepreneur.
18
54060
2142
01:08
He runs a little shop
19
56202
1742
01:09
in one of the back streets of Mumbai.
20
57944
2003
01:11
He has this little 10-square-meter store,
21
59947
3048
01:14
where so much is being done.
22
62995
2150
01:17
It's incredible, because I couldn't believe my eyes
23
65145
1905
01:19
when I once just happened to bump into him.
24
67050
2483
01:21
Basically, what he does is, he has all these services
25
69533
2125
01:23
for micro-payments and booking tickets
26
71658
2753
01:26
and all kinds of basic things that you would go online for,
27
74411
3333
01:29
but he does it for people offline
28
77744
2189
01:31
and connects to the digital world.
29
79933
1997
01:33
More importantly, he makes his money
30
81930
1505
01:35
by selling these mobile recharge coupons, you know,
31
83435
2593
01:38
for the prepaid subscriptions.
32
86028
2275
01:40
But then, in the backside, he's got this little nook
33
88303
3241
01:43
with a few of his employees
34
91544
2573
01:46
where they can fix almost anything.
35
94117
2584
01:48
Any cell phone, any gadget you can bring them, they can fix it.
36
96701
3258
01:51
And it's pretty incredible because I took my iPhone there,
37
99959
3118
01:55
and he was like, "Yeah, do you want an upgrade?"
38
103077
2169
01:57
"Yes." (Laughter)
39
105246
2318
01:59
I was a bit skeptical, but then, I decided
40
107564
1940
02:01
to give him a Nokia instead. (Laughter)
41
109504
4633
02:06
But what I was amazed about is this reverse engineering
42
114137
5215
02:11
and know-how that's built into this little two meters of space.
43
119352
4952
02:16
They have figured out everything that's required
44
124304
2591
02:18
to dismantle, take things apart,
45
126895
2026
02:20
rewrite the circuitry, re-flash the firmware,
46
128921
2959
02:23
do whatever you want to with the phone,
47
131880
1967
02:25
and they can fix anything so quickly.
48
133847
2569
02:28
You can hand over a phone this morning
49
136416
2000
02:30
and you can go pick it up after lunch,
50
138416
1920
02:32
and it was quite incredible.
51
140336
1920
02:34
But then we were wondering whether this is
52
142256
1571
02:35
a local phenomenon, or is truly global?
53
143827
2542
02:38
And, over time, we started understanding
54
146369
2250
02:40
and systematically researching
55
148619
1719
02:42
what this tinkering ecosystem is about,
56
150338
2116
02:44
because that is something that's happening
57
152454
1605
02:46
not just in one street corner in Mumbai.
58
154059
2032
02:48
It's actually happening in all parts of the country.
59
156091
3114
02:51
It's even happening in Africa, like, for example,
60
159205
2261
02:53
in Cape Town we did extensive research on this.
61
161466
2047
02:55
Even here in Doha I found this little nook
62
163513
3195
02:58
where you can get alarm clocks and watches fixed,
63
166708
2887
03:01
and it's a lot of tiny little parts. It's not easy.
64
169595
3201
03:04
You've got to try it on your own to believe it.
65
172796
2113
03:06
But what fuels this?
66
174909
1554
03:08
It's this entire ecosystem of low-cost parts
67
176463
3508
03:11
and supplies that are produced all over the world, literally,
68
179971
3306
03:15
and then redistributed to basically service this industry,
69
183277
3766
03:19
and you can even buy salvaged parts.
70
187043
2171
03:21
Basically, you don't have to necessarily buy
71
189214
2156
03:23
brand new things. You have condemned computers
72
191370
2463
03:25
that are stripped apart,
73
193833
1307
03:27
and you can buy salvaged components
74
195140
1570
03:28
and things that you can reassemble in a new configuration.
75
196710
3821
03:32
But what does this new, sort of, approach give us?
76
200531
3481
03:36
That's the real question, because this is something
77
204012
1920
03:37
that's been there, part of every society
78
205932
2225
03:40
that's deprived of enough resources.
79
208157
2366
03:42
But there's an interesting paradigm.
80
210523
1897
03:44
There's the traditional crafts,
81
212420
1492
03:45
and then there's the technology crafts.
82
213912
2003
03:47
We call it the technology crafts because these are emerging.
83
215915
2208
03:50
They're not something that's been established.
84
218123
2072
03:52
It's not something that's institutionalized.
85
220195
2667
03:54
It's not taught in universities.
86
222862
1771
03:56
It's taught [by] word of mouth,
87
224633
1723
03:58
and it's an informal education system around this.
88
226356
1909
04:00
So we said, "What can we get out of this?
89
228265
2802
04:03
You know, like, what are the key values that we can get out of this?"
90
231067
2734
04:05
The main thing is a fix-it-locally culture,
91
233801
2345
04:08
which is fantastic because it means that your product
92
236146
2340
04:10
or your service doesn't have to go through
93
238486
2045
04:12
a huge bureaucratic system to get it fixed.
94
240531
2608
04:15
It also affords us cheap fabrication, which is fantastic,
95
243139
3079
04:18
so it means that you can do a lot more with it.
96
246218
2032
04:20
And then, the most important thing is,
97
248250
2314
04:22
it gives us large math for low cost.
98
250564
2376
04:24
So it means that you can actually embed
99
252940
2329
04:27
pretty clever algorithms and lots of other kinds
100
255269
3525
04:30
of extendable ideas into really simple devices.
101
258794
3658
04:34
So, what we call this is a silicon cottage industry.
102
262452
4808
04:39
It's basically what was the system or the paradigm
103
267260
2946
04:42
before the industrial revolution is now re-happening
104
270206
2464
04:44
in a whole new way in small digital shops
105
272670
3008
04:47
across the planet in most developing countries.
106
275678
3081
04:50
So, we kind of toyed around with this idea,
107
278759
4134
04:54
and we said, "What can we do with this?
108
282893
1678
04:56
Can we make a little product or a service out of it?"
109
284571
2528
04:59
So one of the first things we did is this thing called
110
287099
2420
05:01
a multimedia platform. We call it a lunch box.
111
289519
2396
05:03
Basically one of the contexts that we studied was
112
291915
2751
05:06
schools in very remote parts of India.
113
294666
3487
05:10
So there is this amazing concept called the one-teacher school,
114
298153
3259
05:13
which is basically a single teacher who is a multitasker
115
301412
2702
05:16
who teaches this amazing little social setting.
116
304114
2477
05:18
It's an informal school,
117
306591
1537
05:20
but it's really about holistic education.
118
308128
2159
05:22
The only thing that they don't have
119
310287
1238
05:23
is access to resources. They don't even have a textbook
120
311525
2394
05:25
sometimes, and they don't even have a proper curriculum.
121
313919
2827
05:28
So we said, "What can we do to empower this teacher
122
316746
3504
05:32
to do more?" How to access the digital world?
123
320250
2812
05:35
Instead of being the sole guardian of information,
124
323062
2562
05:37
be a facilitator to all this information.
125
325624
2404
05:40
So we said, "What are the steps required to empower the teacher?"
126
328028
3384
05:43
How do you make this teacher into a digital gateway,
127
331412
2655
05:46
and how do you design an inexpensive multimedia platform
128
334067
2532
05:48
that can be constructed locally and serviced locally?"
129
336599
2992
05:51
So we walked around.
130
339591
2343
05:53
We went and scavenged the nearby markets,
131
341934
2290
05:56
and we tried to understand, "What can we pick up that will make this happen?"
132
344224
4021
06:00
So the thing that we got
133
348245
2527
06:02
was a little mobile phone with a little pico projector
134
350772
3207
06:05
that comes for about 60 dollars.
135
353979
2337
06:08
We went a bought a flashlight with a very big battery,
136
356316
2456
06:10
and a bunch of small speakers.
137
358772
1790
06:12
So essentially, the mobile phone gives us
138
360562
2298
06:14
a connected multimedia platform.
139
362860
1924
06:16
It allows us to get online and allows us to load up files
140
364784
3485
06:20
of different formats and play them.
141
368269
2351
06:22
The flashlight gives us this really intense, bright L.E.D.,
142
370620
3026
06:25
and six hours worth of rechargeable battery pack,
143
373646
2991
06:28
and the lunch box is a nice little package
144
376637
2216
06:30
in which you can put everything inside,
145
378853
2047
06:32
and a bunch of mini speakers to sort of
146
380900
1563
06:34
amplify the sound large enough.
147
382463
1418
06:35
Believe me, those little classrooms are really noisy.
148
383881
3539
06:39
They are kids who scream at the top of their voices,
149
387420
2593
06:42
and you really have to get above that.
150
390013
1660
06:43
And we took it back to this little tinkering setup
151
391673
2721
06:46
of a mobile phone repair shop,
152
394394
2090
06:48
and then the magic happens.
153
396484
1428
06:49
We dismantle the whole thing,
154
397912
1381
06:51
we reassemble it in a new configuration,
155
399293
2357
06:53
and we do this hardware mashup,
156
401650
2178
06:55
systematically training the guy how to do this.
157
403828
2609
06:58
Out comes this, a little lunch box -- form factor.
158
406437
3455
07:01
(Applause)
159
409892
6826
07:08
And we systematically field tested,
160
416718
3018
07:11
because in the field testing we learned some
161
419736
2368
07:14
important lessons, and we went through many iterations.
162
422104
2517
07:16
One of the key issues was battery consumption and charging.
163
424621
2695
07:19
Luminosity was an issue, when you have too much bright sunlight outside.
164
427316
3978
07:23
Often the roofs are broken, so you don't have enough
165
431294
2552
07:25
darkness in the classroom to do these things.
166
433846
3128
07:28
We extended this idea. We tested it many times over,
167
436974
2842
07:31
and the next version we came up with was a box
168
439816
2578
07:34
that kind of could trickle charge on solar energy,
169
442394
2380
07:36
but most importantly connect to a car battery,
170
444774
2799
07:39
because a car battery is a ubiquitous source of power
171
447573
2994
07:42
in places where there's not enough electricity
172
450567
2207
07:44
or erratic electricity.
173
452774
1960
07:46
And the other key thing that we did was
174
454734
1969
07:48
make this box run off a USB key, because we realized
175
456703
2462
07:51
that even though there was GPRS and all that on paper,
176
459165
3354
07:54
at least, in theory, it was much more efficient
177
462519
2575
07:57
to send the data on a little USB key by surface mail.
178
465094
3890
08:00
It might take a few days to get there,
179
468984
1840
08:02
but at least it gets there in high definition
180
470824
2374
08:05
and in a reliable quality.
181
473198
2215
08:07
So we made this box, and we tested it again
182
475413
2282
08:09
and again and again, and we're going through
183
477695
1535
08:11
multiple iterations to do these things.
184
479230
1549
08:12
But it's not limited to just education.
185
480779
2969
08:15
This kind of a technique or metrology
186
483748
1866
08:17
can actually be applied to other kinds of areas,
187
485614
2012
08:19
and I'm going to tell you one more little story.
188
487626
1908
08:21
It's about this little device called a medi-meter.
189
489534
2455
08:23
It's basically a little health care screening tool that we developed.
190
491989
3367
08:27
In India, there is a context of these amazing people,
191
495356
3327
08:30
the health care workers called ASHA workers.
192
498683
2279
08:32
They are essentially foot soldiers for the health care system
193
500962
2417
08:35
who live in the local community and are trained
194
503379
2384
08:37
with basic tools and basic concepts of health care,
195
505763
2568
08:40
and the main purpose is basically to inform people
196
508331
3762
08:44
to basically, how to lead a better life, but also
197
512093
3533
08:47
to divert or sort of make recommendations
198
515626
3228
08:50
of what kind of health care should they approach?
199
518854
2674
08:53
They are basically referral services, essentially.
200
521528
2712
08:56
But the problem with that is that we realized
201
524240
2308
08:58
after a bunch of research that they are amazing
202
526548
4190
09:02
at referring people to the nearest clinic
203
530738
2480
09:05
or the public health care system, but what happens at the
204
533218
2873
09:08
public health care system is this: these incredibly long lines
205
536091
4078
09:12
and too many people who overload the system
206
540169
2810
09:14
simply because there's not enough doctors and facilities
207
542979
2566
09:17
for the population that's being referred.
208
545545
2202
09:19
So everything from a common cold
209
547747
2119
09:21
to a serious case of malaria gets almost the same
210
549866
2660
09:24
level of attention, and there's no priorities.
211
552526
3044
09:27
So we said, "Come on, there's got to be a better way
212
555570
2071
09:29
of doing this for sure."
213
557641
1801
09:31
So we said, "What can we do with the ASHA worker
214
559442
2577
09:34
that'll allow this ASHA worker to become an interesting filter,
215
562019
3931
09:37
but not just a filter, a really well thought through referral
216
565950
2515
09:40
system that allows load balancing of the network,
217
568465
3481
09:43
and directs patients to different sources of health care
218
571946
3939
09:47
based on the severity or the criticalness of those situations?"
219
575885
3880
09:51
So the real key question was,
220
579765
1981
09:53
how do we empower this woman?
221
581746
1668
09:55
How do we empower her with simple tools
222
583414
1927
09:57
that's not diagnostic but more screening in nature
223
585341
2951
10:00
so she at least knows how to advise the patients better?
224
588292
3780
10:04
And that'll make such a huge difference on the system,
225
592072
2028
10:06
because the amount of waiting time and the amount of
226
594100
4918
10:11
distances that people need to travel, often sometimes
227
599018
1920
10:12
seven to 15 kilometers, sometimes by foot,
228
600938
2673
10:15
to get a simple health check done, is very, very detrimental
229
603611
5463
10:21
in the sense that it really dissuades people
230
609074
2454
10:23
from getting access to health care.
231
611528
2009
10:25
So if there was something that she could do,
232
613537
2035
10:27
that would be amazing.
233
615572
1109
10:28
So what we did was that we converted this device
234
616681
3061
10:31
into a medical device.
235
619742
1817
10:33
I want to demo this actually,
236
621559
1276
10:34
because it's a very simple process.
237
622835
2673
10:37
Bruno, do you want to join us? (Cheers)
238
625508
2409
10:39
Come along. (Applause)
239
627917
6202
10:46
So, what we're going to do is that
240
634119
2925
10:49
we're going to measure a few basic parameters on you,
241
637044
2972
10:52
including your pulse rate and the amount of oxygen
242
640016
2855
10:54
that's there in your blood.
243
642871
1873
10:56
So you're going to put your thumb on top of this.
244
644744
3291
11:00
Bruno Giussani: Like this, works?
245
648035
1774
11:01
Vinay Venkatraman: Yeah. That's right. BG: Okay.
246
649809
1666
11:03
VV: So I'm going to start it up. I hope it works.
247
651475
4008
11:07
(Beeps) It even beeps, because it's an alarm clock, after all.
248
655483
4350
11:11
So ... (Laughter)
249
659833
2012
11:13
So I take it into the start position, and then
250
661845
4391
11:18
I press the read button. (Beeps)
251
666236
3612
11:21
So it's taking a little reading from you. (Beeps)
252
669848
5481
11:27
And then the pointer goes and points to three different options.
253
675329
2778
11:30
Let's see what happens here.
254
678107
3275
11:33
(Beeps) Oh Bruno, you can go home, actually.
255
681382
2083
11:35
BG: Great. Good news. (Applause)
256
683465
3836
11:39
VV: So ... (Applause)
257
687301
2345
11:41
So the thing about this is that
258
689646
3217
11:44
if the pointer, unfortunately, had pointed to the red spot,
259
692863
4105
11:48
we would have to rush you to a hospital.
260
696968
1846
11:50
Luckily, not today. And if it had pointed to the orange
261
698814
4120
11:54
or the amber, it basically meant you had to have,
262
702934
2829
11:57
sort of, more continuous care from the health care worker.
263
705763
3044
12:00
So that was a very simple three-step screening process
264
708807
2351
12:03
that could basically change the equation
265
711158
2115
12:05
of how public health care works in so many different ways.
266
713273
2740
12:08
BG: Thank you for the good news. VV: Yeah.
267
716013
1897
12:09
(Applause)
268
717910
4393
12:14
So, very briefly, I'll just explain to you how this is done,
269
722303
3440
12:17
because that's the more interesting part.
270
725743
2290
12:20
So essentially, the three things that are required
271
728033
2694
12:22
to make this conversion from this guy to this guy
272
730727
4528
12:27
is a cheap remote control for a television
273
735255
4129
12:31
that you can almost find in every home today,
274
739384
2911
12:34
some parts from a computer mouse, basically,
275
742295
3714
12:38
something that you can scavenge for very low cost,
276
746009
3863
12:41
and a few parts that have to be pre-programmed.
277
749872
2911
12:44
Basically this is a micro-controller with a few
278
752783
2401
12:47
extra components that can be shipped for very little cost
279
755184
2795
12:49
across the world, and that's what is all required
280
757979
2993
12:52
with a little bit of local tinkering talent
281
760972
2391
12:55
to convert the device into something else.
282
763363
2787
12:58
So we are right now doing some systematic field tests
283
766150
3396
13:01
to basically ascertain whether something like this actually
284
769546
3050
13:04
makes sense to the ASHA worker.
285
772596
1567
13:06
We are going through some reference tests to compare it
286
774163
3544
13:09
against professional equipment to see if there's a degree
287
777707
3458
13:13
of change in efficacy and if it actually makes an impact
288
781165
2322
13:15
in people's lives. But most importantly,
289
783487
2608
13:18
what we are trying to do right now
290
786095
1795
13:19
is we are trying to scale this up, because there
291
787890
2254
13:22
are over 250,000 ASHA workers on the ground
292
790144
2687
13:24
who are these amazing foot soldiers, and if we can
293
792831
2737
13:27
give at least a fraction of them the access to these things,
294
795568
3560
13:31
it just changes the way the economics of public health care
295
799128
2958
13:34
works, and it changes the way systems actually function,
296
802086
3011
13:37
not just on a systematic planning level,
297
805097
4266
13:41
but also in a very grassroots, bottom-up level.
298
809363
3185
13:44
So that's it, and we hope to do this in a big way.
299
812548
2801
13:47
Thank you. (Applause)
300
815349
