Mouse 2.0: Multi-touch Meets the Mouse
In this paper, the authors present novel input devices that combine the standard capabilities of a computer mouse with multi-touch sensing. Their goal is to enrich traditional pointer-based desktop interactions with touch and gestures. To chart the design space, they present five different multi-touch mouse implementations. Each explores a different touch sensing strategy, which leads to differing form-factors and hence interactive possibilities. In addition to the detailed description of hardware and software implementations of their prototypes, they discuss the relative strengths, limitations and affordances of these novel input devices as informed by the results of a preliminary user study.
