Android Optometry
We’ve commented before about the ability of telemedicine solutions to bring cutting edge technology and quality of care to emerging economies. One example is some of the recent work that the Camera Culture Group from MIT’s Media Lab has done by building a clever optometry solution into an accessory and an application for Android-powered smartphones (HT: Engadget).
The concept is very cool. Many optometrists today use autorefractors, machines which scans the images formed on the back of a patient’s retina to get a rough, but automated, measure on the quality of your vision. Optometrists will then use phoropters to get to a precise enough measure of your eyes as to be able to prescribe lenses for contacts/glasses.
The problem with this approach is that autorefractors and phoropters are too expensive and too time consuming for widespread use in many places around the world. The NETRA solution that the Camera Culture Group came up with was to build an accessory and an application which force a user to make a pair of lines overlap using controls on the phone. Doing this repeatedly lets the application do a calculation similar to what is done by an autorefractor to calculate the quality of the user’s vision in a process which is much faster (several minutes) and cheaper than a standard eye exam (more details in the video and images below)
The project website shows a very compelling table which compares the relative prices and accuracies of optometry solutions in existence today.
It’ll be interesting to see where this technology can go once displays similar to Apple’s Retina Display become cheaper and more prevalent. This example definitely shows the power of telemedicine approaches and is hopefully a harbinger for more equally compelling and innovative solutions for the needs of scientists and doctors around the world.
Amateur Android Astronomer
On Bench Press, we usually discuss technologies to empower scientists to do research or to better communicate with each other and with the public. But, technologies can also help the “casual” fan appreciate science as well. Case in point: Google recently announced a new application available for Android phones called Google Sky Map. The concept is quite ingenious. If ancient navigators used starcharts and compasses to determine their location, why can’t a phone that knows its location (via built-in GPS) and its direction (via magnetometer and accelerometer) be used to figure out what stars are up above?
Or in other words, Google took this physical setup (very cute setup from Google for how Google Sky Map works) of what is basically a sextant, compass, and calendar:
And replaced it with a smartphone:
I haven’t had a chance to play with it (as I don’t own a G1), but the application looks very nicely packaged. You can use it to figure out what stars are right above you. But, the coolest feature is the ability to use the application to point you in the direction of something you’re interested in seeing (e.g. the planet Saturn).
More details are in the video below. You can get Sky Map for Android through the Android Market. For anyone who’s tried it, let us know what you think in the comments!
