We investigate the differences -in terms of both quantitative performance and subjective preferencebetween 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.
Comparisons between unimanual direct touch and mouse input indicate roughly equivalent performance times for selection tasks REF .
