Most of the iPhone controller hacks I’ve seen tend to use the accelerometer along with on on-board camera. Walky is a bipedal walking robot that’s controlled using a natural gestural interface. [via GeekyGadgets]

Yuta Sugiura and his colleagues at the Graduate School of Media Design, Keio University, have developed a new control scheme for robots and virtual characters called Walky for the iPhone. Rather than using a cumbersome game controller or keyboard, which may pose a problem for novice users, they can use Walky to control walking, turning, jumping, kicking, and other actions through simple finger gestures on the iPhone’s touch screen.
