Add-on turns a smartphone camera into a joystick (video)
One of the more irritating aspects of touchscreen gaming is almost certainly the inevitability of blocking the screenas you play — particularly with smaller devices like smartphones. A new peripheral being developed by Kelo University takes an interesting approach to the problem — using the device to transform the gadget’s camera into a three-axis joystick of sorts by detecting the movement of markings on the add-on. According to its creators, the accuracy of the joystick depends largely on the precision of the phone’s hardware. Check it out in action after the break.
