Power in the Palm of People
ZuseZ3 1941
I think there will be a world market for
about five computers
- Thomas Watson, Chairman of IBM, 1941
The Reach
The Power
640KB of memory ought to be enough for
anybody -- - Bill Gates, in 1981
Windows Phone 2014
Quad Core Processor; 2048 MB
RAM; A Convergence Device
IBM PC in 1981
Smart phones to dwarf world population
The Value
FDA predicts more than 50% smart phones users will download a healthcare
app by 2018 (1.7 Billion) - Plans to regulate some healthcare apps , but also
will permit some without premarket reviews

Current Configuration of a mid-range smartphone
• 1.2 GHz CPU, 8GB of Flash, 1GB of RAM
By year 2020, mobile phones may have
• 10 GHz CPU, 80GB of Flash, 8GB RAM
• With a battery power to last a fortnight and a host of
high-precision on-board sensors!!
• Why do we need a dedicated medical instrument?

The opportunity…
• Digital India project: Government to ensure that every Indian has smartphone by 2019 – Economic Times, Aug 25 2014
India is said to have 1 doctor for 1700 people. But is every doctor reaching 1700 people?
• Monitoring in rural PHCs, in partnership with the government
• Regular monitoring based preventive healthcare for insurance
• Elderly people monitoring for old age homes
• Bundled offerings with Telecom providers
• Inclusive and affordable Telemedicine for hospitals
The Business?
• Research at the intersection of Medical domain and Computer Science needing Multi-disciplinary collaboration
• Affordable Healthcare is a India-specific (Emerging Market) problem – has to be researched and solved in India
How to go about it?
