  Medium-sized touch displays, sized 30 to 50 inches, are becoming more
affordable and more widely available. Prolonged use of such displays can result
in arm fatigue or skin irritation, especially when multiple long distance drags
are involved. To address this issue, we present TapDrag, an alternative
dragging technique that complements traditional dragging with a simple tapping
gesture on both ends of the intended dragging path. Our experimental evaluation
suggests that TapDrag is a viable alternative to traditional dragging with
faster task completion times for long distances. Qualitative user feedback
indicates that TapDrag helps prevent skin irritation. A reduction in arm
fatigue remains unconfirmed.
