Sure, the Evo's front-facing camera enables you to call your snookums and let them see your mug while you two exchange sweet nothings. But, wouldn't it be much better if you could tell your phone to talk to the hand? Now it can... at least in theory, with the availability eyeSight libraries for Android. EyeSight's Natural User Interface relies on a phone's camera to detect hand motions, enabling developers to write apps that change tracks, ignore callers, and display text messages with a wave. The down-side is that those apps need to be specifically written to work in this way, and while the libraries have been available for Nokia handsets since last year, right now we're seeing a whopping four programs that use it (including the hugely important "Fart Control," which turns your phone into a "motion detecting fart machine"). So, you should probably not expect a revolution here either. Video demo from the Nokia days is embedded just below.
