Adding multi-touch sensing to the surface of a mouse has the potential
to substantially increase the number of interactions available
to the user. However, harnessing this increased bandwidth is
challenging, since the user must perform multi-touch interactions
while holding the device and using it as a regular mouse. In this
paper we describe the design challenges and formalize the design
space of multi-touch mice interactions. From our design space
categories we synthesize four interaction models which enable the
use of both multi-touch and mouse interactions on the same device.
We describe the results of a controlled user experiment evaluating
the performance of these models in a 2D spatial manipulation
task typical of touch-based interfaces and compare them to
interacting directly on a multi-touch screen and with a regular
mouse. We observed that our multi-touch mouse interactions were
overall slower than the chosen baselines; however, techniques
providing a single focus of interaction and explicit touch activation
yielded better performance and higher preferences from our
participants. Our results expose the difficulties in designing multitouch
mice interactions and define the problem space for future
research in making these devices effective.
