3-Axis Analog Joystick Uses iPhone Camere (Video)

Posted on April 3, 2012 by

This is a very interesting way of bringing an analog joystick to the iPhone. This elastic device, under development by a research group at Keio University, converts the camera on your iPhone into a fully functional 3-axis joystick.

The way this system works is very simple. 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.

The camera is detecting the markers right now. When you press the device, like this, the markers move further apart, or they move horizontally or vertically, or they get skewed. So you can give the system a variety of inputs.
