“…Direct-touch interactive tabletop displays have been the focus of numerous research projects [11,34,36,37,38,41] and appear to provide several benefits over traditional desktop displays. One of the most often argued benefits is the notion that interacting with an application through directly touching graphical elements is a more "natural" or "compelling" approach than working indirectly with a mouse or other pointing device.…”

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.

In games where skills such as targeting are critical to winning, it is difficult for players with different skill levels to have a competitive and engaging experience. Although several mechanisms for accommodating different skill levels have been proposed, traditional approaches can be too obvious and can change the nature of the game. For games involving aiming, we propose the use of target assistance techniques (such as area cursors, target gravity, and sticky targets) to accommodate skill imbalances. We compared three techniques in a study, and found that area cursors and target gravity significantly reduced score differential in a shooting-gallery game. Further, less skilled players reported having more fun when the techniques helped them be more competitive, and even after they learned assistance was given, felt that this form of balancing was good for group gameplay. Our results show that target assistance techniques can make target-based games more competitive for shared play.

“…The gain is increased on the approach to the target and decreased while inside the target thus increasing and decreasing the motor space at critical moments in the selection process. TractorBeam (Parker et al, 2005) is a hybrid point-touch technique that aids selection by expanding the cursor or the target, or by snapping to the target. Worden et al (1997) implemented 'Sticky Icons' by decreasing the mouse control-display gain when the cursor enters the icon.…”
