Smart watches normally have small displays and so controlling them can be trickier than smart phones or other devices. There are also lots of situations, when you need to control the watch, but both of your hands are occupied. Darthmouth team has been looking for a solution to this problem and came out with WristWhirl smart watch prototype. They integrated smart control capability in to watch strap where they put 12 IR proximity sensors and piezo vibration sensor that would accept biomechanical gestures.
The watch is equipped with 2’’ TFT display. Inside the watch an Arduino DUO is ticking. As a smart watch it can do lots of things including Google map navigation, music player where user can scroll through playlists with simple gestures. No watch would be great without games. There is an experimental Tetris which accepts wrist swipes, wrist extension and wrist flexion combination.
