The following technical report is available from http://aib.informatik.rwth-aachen.de: Utilizing optical sensors from mice for new input devices Sebastian Ullrich, Jakob T. Valvoda, Torsten Kuhlen AIB 2006-15 This paper introduces approaches towards the development of intuitive input devices built with optical sensors from mice. The two main ideas are spatial reconfiguration of the sensor and advanced interpretation of the sensor data. We present new concepts for various input devices that are easy to rebuild. A prototype for kinematics manipulation of virtual characters has been constructed and algorithms for data interpretation have been implemented and evaluated.
