Phones. there just isn’t enough room on them for proper gaming. That must be why we are always looking for better ways to attach joysticks to them. If you put it on your screen, you are blocking some of the action and that’s no good. A research group at Keio University has the answer. The 3-Axis analog joystick is an elastic device that goes over the front facing camera of your smartphone and acts as a joystick.
It uses small markers that can be tracked by the camera, and so the phone can register the movement as input for the games. So this won’t block the screen or get in the way while you are playing. The joystick can also go onto the phone’s rear camera and work the same way if you needed to.
It’s a great concept. Hopefully we will see more of it one day, but if we do it will be a long time in coming.
