Direct-touch vs. mouse input for tabletop displays

We investigate the differences ? in terms of both quantitative performance and subjective preference ? between direct-touch and mouse input for unimanual and bimanual tasks on tabletop displays. The results of two experiments show that for bimanual tasks performed on tabletops, users benefit from direct-touch input. However, our results also indicate that mouse input may be more appropriate for a single user working on tabletop tasks requiring only single-point interaction.
