That cellphones are full-fledged computers useful for a lot more than basic communications is well known, but actual, practical applications are just coming online. To date, most have been in the transfer of market information (CellBazaar) and money (M-PESA), with a host of trials in the medical arena. But getting doctors to use new technology isn’t always easy–unless it fits right into what they are used to doing.

ClickDiagnostics, a new company spawned at MIT (and winner of the MIT Enterprise Forum’s $100K competition in the “development” field), may have accomplished that. The idea is to use cell phones in the field, particularly remote rural areas, to take pictures of people’s eyes and skin, then transmit those images to doctors for diagnosis of cataracts and skin cancer. In an initial test last winter students travelled to Bangladesh to shoot images, then tested their quality with doctors at Massachusetts General Hospital (aka MGH, aka “man’s greatest hospital”) in Boston. The doctors said they were of high enough quality to make an initial diagnosis and prescribe a treatment regimen–or point to the need for immediate hospital-related care.

In addition to the common skin disease prevalent in all developing countries, these simple cell phone images can detect the onset of HIV, Malaria, Hepatitis C, and TB. To the extent the product can be deployed in the field, it could have a huge impact on the early recognition and treatment of these debilitating and potentially deadly diseases.

With the MIT prize and some seed funding under its belt, ClickDiagnostics has its first contract to provide service in Egpyt, starting this fall.

Last spring I completed an in-depth research report on the role cell phones in helping Americans get work and make money. Released by the independent New Millennium Research Council (NMRC) think tank, Cell Phones Provide Significant Economic Gains for Low-Income American Households concludes that providing cell phones to the 38 percent of America’s 45 million poorest households now without them — including millions of seniors, Hispanics, African-Americans and rural residents — could help them get work or make money worth $2.9 billion-$11 billion. The study is based on two surveys: a scientific poll by Opinion Research Corporation (ORC) of 1,005 Americans and a statistically large online sampling of 110,000 prepaid cellphone users (provided by Tracfone). The study is the first in the U.S. to zero in on potential economic and public safety benefits to those in the bottom two quintiles of household income (less than $35,000), who are much less likely to own cell phones. Those who do not now own a cell phone tend to be older (37 percent are retired), less educated (29 percent have a high school education or less), low income (38 percent make less than $35,000 a year) or unemployed (30 percent).
