Smartphone Joystick Uses iPhone's Camera for Input [Video]

Researchers at Kelo University are developing a joystick that uses your iPhone's camera for input rather than the touchscreen, reports AppAdvice.

Kelo University's Assistant Professor, Yasutoshi Makino says,


"There are small markers in this elastic device and the markers are detected by this built-in front-facing mobile phone camera. By tracking how the markers move as the elastic device deforms, this system enables a variety of inputs. Basically, the system's precision depends on hardware factors, like the camera resolution and refresh rate."
