Vinay Venkatraman: Technology crafts for the digitally underserved

Filmed:

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.

Vinay Venkatraman aims to design technological devices for the "bottom of the pyramid" rather than simply for the affluent. Full bio

Frugal Digital is essentially a small research group at C.I.D.
00:12
where we are looking to find
00:17
alternate visions of how to create a digitally inclusive society.
00:19
That's what we're after.
00:24
And we do this because we actually believe
00:26
that silicon technology today is mostly about
00:28
a culture of excess.
00:31
It's about the fastest and the most efficient
00:33
and the most dazzling gadget you can have,
00:35
while about two-thirds of the world
00:38
can hardly reach the most basic of this technology
00:40
to even address fundamental needs in life,
00:44
including health care, education
00:48
and all these kinds of very fundamental issues.
00:50
So before I start, I want to talk about a little anecdote,
00:54
a little story about a man I met once in Mumbai.
00:57
So this man, his name is Sathi Shri.
01:01
He is an outstanding person,
01:03
because he's a small entrepreneur.
01:06
He runs a little shop
01:08
in one of the back streets of Mumbai.
01:09
He has this little 10-square-meter store,
01:11
where so much is being done.
01:14
It's incredible, because I couldn't believe my eyes
01:17
when I once just happened to bump into him.
01:19
Basically, what he does is, he has all these services
01:21
for micro-payments and booking tickets
01:23
and all kinds of basic things that you would go online for,
01:26
but he does it for people offline
01:29
and connects to the digital world.
01:31
More importantly, he makes his money
01:33
by selling these mobile recharge coupons, you know,
01:35
for the prepaid subscriptions.
01:38
But then, in the backside, he's got this little nook
01:40
with a few of his employees
01:43
where they can fix almost anything.
01:46
Any cell phone, any gadget you can bring them, they can fix it.
01:48
And it's pretty incredible because I took my iPhone there,
01:51
and he was like, "Yeah, do you want an upgrade?"
01:55
"Yes." (Laughter)
01:57
I was a bit skeptical, but then, I decided
01:59
to give him a Nokia instead. (Laughter)
02:01
But what I was amazed about is this reverse engineering
02:06
and know-how that's built into this little two meters of space.
02:11
They have figured out everything that's required
02:16
to dismantle, take things apart,
02:18
rewrite the circuitry, re-flash the firmware,
02:20
do whatever you want to with the phone,
02:23
and they can fix anything so quickly.
02:25
You can hand over a phone this morning
02:28
and you can go pick it up after lunch,
02:30
and it was quite incredible.
02:32
But then we were wondering whether this is
02:34
a local phenomenon, or is truly global?
02:35
And, over time, we started understanding
02:38
and systematically researching
02:40
what this tinkering ecosystem is about,
02:42
because that is something that's happening
02:44
not just in one street corner in Mumbai.
02:46
It's actually happening in all parts of the country.
02:48
It's even happening in Africa, like, for example,
02:51
in Cape Town we did extensive research on this.
02:53
Even here in Doha I found this little nook
02:55
where you can get alarm clocks and watches fixed,
02:58
and it's a lot of tiny little parts. It's not easy.
03:01
You've got to try it on your own to believe it.
03:04
But what fuels this?
03:06
It's this entire ecosystem of low-cost parts
03:08
and supplies that are produced all over the world, literally,
03:11
and then redistributed to basically service this industry,
03:15
and you can even buy salvaged parts.
03:19
Basically, you don't have to necessarily buy
03:21
brand new things. You have condemned computers
03:23
that are stripped apart,
03:25
and you can buy salvaged components
03:27
and things that you can reassemble in a new configuration.
03:28
But what does this new, sort of, approach give us?
03:32
That's the real question, because this is something
03:36
that's been there, part of every society
03:37
that's deprived of enough resources.
03:40
But there's an interesting paradigm.
03:42
There's the traditional crafts,
03:44
and then there's the technology crafts.
03:45
We call it the technology crafts because these are emerging.
03:47
They're not something that's been established.
03:50
It's not something that's institutionalized.
03:52
It's not taught in universities.
03:54
It's taught [by] word of mouth,
03:56
and it's an informal education system around this.
03:58
So we said, "What can we get out of this?
04:00
You know, like, what are the key values that we can get out of this?"
04:03
The main thing is a fix-it-locally culture,
04:05
which is fantastic because it means that your product
04:08
or your service doesn't have to go through
04:10
a huge bureaucratic system to get it fixed.
04:12
It also affords us cheap fabrication, which is fantastic,
04:15
so it means that you can do a lot more with it.
04:18
And then, the most important thing is,
04:20
it gives us large math for low cost.
04:22
So it means that you can actually embed
04:24
pretty clever algorithms and lots of other kinds
04:27
of extendable ideas into really simple devices.
04:30
So, what we call this is a silicon cottage industry.
04:34
It's basically what was the system or the paradigm
04:39
before the industrial revolution is now re-happening
04:42
in a whole new way in small digital shops
04:44
across the planet in most developing countries.
04:47
So, we kind of toyed around with this idea,
04:50
and we said, "What can we do with this?
04:54
Can we make a little product or a service out of it?"
04:56
So one of the first things we did is this thing called
04:59
a multimedia platform. We call it a lunch box.
05:01
Basically one of the contexts that we studied was
05:03
schools in very remote parts of India.
05:06
So there is this amazing concept called the one-teacher school,
05:10
which is basically a single teacher who is a multitasker
05:13
who teaches this amazing little social setting.
05:16
It's an informal school,
05:18
but it's really about holistic education.
05:20
The only thing that they don't have
05:22
is access to resources. They don't even have a textbook
05:23
sometimes, and they don't even have a proper curriculum.
05:25
So we said, "What can we do to empower this teacher
05:28
to do more?" How to access the digital world?
05:32
Instead of being the sole guardian of information,
05:35
be a facilitator to all this information.
05:37
So we said, "What are the steps required to empower the teacher?"
05:40
How do you make this teacher into a digital gateway,
05:43
and how do you design an inexpensive multimedia platform
05:46
that can be constructed locally and serviced locally?"
05:48
So we walked around.
05:51
We went and scavenged the nearby markets,
05:53
and we tried to understand, "What can we pick up that will make this happen?"
05:56
So the thing that we got
06:00
was a little mobile phone with a little pico projector
06:02
that comes for about 60 dollars.
06:05
We went a bought a flashlight with a very big battery,
06:08
and a bunch of small speakers.
06:10
So essentially, the mobile phone gives us
06:12
a connected multimedia platform.
06:14
It allows us to get online and allows us to load up files
06:16
of different formats and play them.
06:20
The flashlight gives us this really intense, bright L.E.D.,
06:22
and six hours worth of rechargeable battery pack,
06:25
and the lunch box is a nice little package
06:28
in which you can put everything inside,
06:30
and a bunch of mini speakers to sort of
06:32
amplify the sound large enough.
06:34
Believe me, those little classrooms are really noisy.
06:35
They are kids who scream at the top of their voices,
06:39
and you really have to get above that.
06:42
And we took it back to this little tinkering setup
06:43
of a mobile phone repair shop,
06:46
and then the magic happens.
06:48
We dismantle the whole thing,
06:49
we reassemble it in a new configuration,
06:51
and we do this hardware mashup,
06:53
systematically training the guy how to do this.
06:55
Out comes this, a little lunch box -- form factor.
06:58
(Applause)
07:01
And we systematically field tested,
07:08
because in the field testing we learned some
07:11
important lessons, and we went through many iterations.
07:14
One of the key issues was battery consumption and charging.
07:16
Luminosity was an issue, when you have too much bright sunlight outside.
07:19
Often the roofs are broken, so you don't have enough
07:23
darkness in the classroom to do these things.
07:25
We extended this idea. We tested it many times over,
07:28
and the next version we came up with was a box
07:31
that kind of could trickle charge on solar energy,
07:34
but most importantly connect to a car battery,
07:36
because a car battery is a ubiquitous source of power
07:39
in places where there's not enough electricity
07:42
or erratic electricity.
07:44
And the other key thing that we did was
07:46
make this box run off a USB key, because we realized
07:48
that even though there was GPRS and all that on paper,
07:51
at least, in theory, it was much more efficient
07:54
to send the data on a little USB key by surface mail.
07:57
It might take a few days to get there,
08:00
but at least it gets there in high definition
08:02
and in a reliable quality.
08:05
So we made this box, and we tested it again
08:07
and again and again, and we're going through
08:09
multiple iterations to do these things.
08:11
But it's not limited to just education.
08:12
This kind of a technique or metrology
08:15
can actually be applied to other kinds of areas,
08:17
and I'm going to tell you one more little story.
08:19
It's about this little device called a medi-meter.
08:21
It's basically a little health care screening tool that we developed.
08:23
In India, there is a context of these amazing people,
08:27
the health care workers called ASHA workers.
08:30
They are essentially foot soldiers for the health care system
08:32
who live in the local community and are trained
08:35
with basic tools and basic concepts of health care,
08:37
and the main purpose is basically to inform people
08:40
to basically, how to lead a better life, but also
08:44
to divert or sort of make recommendations
08:47
of what kind of health care should they approach?
08:50
They are basically referral services, essentially.
08:53
But the problem with that is that we realized
08:56
after a bunch of research that they are amazing
08:58
at referring people to the nearest clinic
09:02
or the public health care system, but what happens at the
09:05
public health care system is this: these incredibly long lines
09:08
and too many people who overload the system
09:12
simply because there's not enough doctors and facilities
09:14
for the population that's being referred.
09:17
So everything from a common cold
09:19
to a serious case of malaria gets almost the same
09:21
level of attention, and there's no priorities.
09:24
So we said, "Come on, there's got to be a better way
09:27
of doing this for sure."
09:29
So we said, "What can we do with the ASHA worker
09:31
that'll allow this ASHA worker to become an interesting filter,
09:34
but not just a filter, a really well thought through referral
09:37
system that allows load balancing of the network,
09:40
and directs patients to different sources of health care
09:43
based on the severity or the criticalness of those situations?"
09:47
So the real key question was,
09:51
how do we empower this woman?
09:53
How do we empower her with simple tools
09:55
that's not diagnostic but more screening in nature
09:57
so she at least knows how to advise the patients better?
10:00
And that'll make such a huge difference on the system,
10:04
because the amount of waiting time and the amount of
10:06
distances that people need to travel, often sometimes
10:11
seven to 15 kilometers, sometimes by foot,
10:12
to get a simple health check done, is very, very detrimental
10:15
in the sense that it really dissuades people
10:21
from getting access to health care.
10:23
So if there was something that she could do,
10:25
that would be amazing.
10:27
So what we did was that we converted this device
10:28
into a medical device.
10:31
I want to demo this actually,
10:33
because it's a very simple process.
10:34
Bruno, do you want to join us? (Cheers)
10:37
Come along. (Applause)
10:39
So, what we're going to do is that
10:46
we're going to measure a few basic parameters on you,
10:49
including your pulse rate and the amount of oxygen
10:52
that's there in your blood.
10:54
So you're going to put your thumb on top of this.
10:56
Bruno Giussani: Like this, works?
11:00
Vinay Venkatraman: Yeah. That's right. BG: Okay.
11:01
VV: So I'm going to start it up. I hope it works.
11:03
(Beeps) It even beeps, because it's an alarm clock, after all.
11:07
So ... (Laughter)
11:11
So I take it into the start position, and then
11:13
I press the read button. (Beeps)
11:18
So it's taking a little reading from you. (Beeps)
11:21
And then the pointer goes and points to three different options.
11:27
Let's see what happens here.
11:30
(Beeps) Oh Bruno, you can go home, actually.
11:33
BG: Great. Good news. (Applause)
11:35
VV: So ... (Applause)
11:39
So the thing about this is that
11:41
if the pointer, unfortunately, had pointed to the red spot,
11:44
we would have to rush you to a hospital.
11:48
Luckily, not today. And if it had pointed to the orange
11:50
or the amber, it basically meant you had to have,
11:54
sort of, more continuous care from the health care worker.
11:57
So that was a very simple three-step screening process
12:00
that could basically change the equation
12:03
of how public health care works in so many different ways.
12:05
BG: Thank you for the good news. VV: Yeah.
12:08
(Applause)
12:09
So, very briefly, I'll just explain to you how this is done,
12:14
because that's the more interesting part.
12:17
So essentially, the three things that are required
12:20
to make this conversion from this guy to this guy
12:22
is a cheap remote control for a television
12:27
that you can almost find in every home today,
12:31
some parts from a computer mouse, basically,
12:34
something that you can scavenge for very low cost,
12:38
and a few parts that have to be pre-programmed.
12:41
Basically this is a micro-controller with a few
12:44
extra components that can be shipped for very little cost
12:47
across the world, and that's what is all required
12:49
with a little bit of local tinkering talent
12:52
to convert the device into something else.
12:55
So we are right now doing some systematic field tests
12:58
to basically ascertain whether something like this actually
13:01
makes sense to the ASHA worker.
13:04
We are going through some reference tests to compare it
13:06
against professional equipment to see if there's a degree
13:09
of change in efficacy and if it actually makes an impact
13:13
in people's lives. But most importantly,
13:15
what we are trying to do right now
13:18
is we are trying to scale this up, because there
13:19
are over 250,000 ASHA workers on the ground
13:22
who are these amazing foot soldiers, and if we can
13:24
give at least a fraction of them the access to these things,
13:27
it just changes the way the economics of public health care
13:31
works, and it changes the way systems actually function,
13:34
not just on a systematic planning level,
13:37
but also in a very grassroots, bottom-up level.
13:41
So that's it, and we hope to do this in a big way.
13:44
Thank you. (Applause)
13:47
(Applause)
