ABSTRACT
Multitouch workstations support direct-touch, bimanual, and mul-
tifinger interaction. Previous studies have separately examined the
benefits of these three interaction attributes over mouse-based in-
teractions. In contrast, we present an empirical user study that con-
siders these three interaction attributes together for a single task,
such that we can quantify and compare the performances of each at-
tribute. In our experiment users select multiple targets using either
a mouse-based workstation equipped with one mouse, or a multi-
touch workstation using either one finger, two fingers (one from
each hand), or multiple fingers. We find that the fastest multitouch
