A team of Keio University has developed a prototype device that converts a front camera of smartphone in to a joystick.
Called 3-Axis Joystick, is a tire lever mounted on the front (or rear) camera on your phone so that the latter detects your movements in real time. Thus acts as a joystick, and even without taking up valuable space on your screen.
More details about this interesting device will find the video below:
