WireTouch: An Open Multi-Touch Tracker based on Mutual Capacitance Sensing

Wagner, Armin; Kaindl, Georg

We present a fully disclosed tracking pipeline based on mutual capacitance sensing. We designed both hard- and software to support and foster experimentation. Without the use of vendor-supplied cap-sense ICs and proprietary software parts, every aspect and parameter of the user interface can be modified with ease. This flexibility gives the researcher a high degree of freedom while designing novel interactive systems. The working prototype of an audio-tactile multi-touch map is presented as an exemplary application.
