TapDrag: An Alternative Dragging Technique on Medium-Sized MultiTouch Displays Reducing Skin Irritation and Arm Fatigue
This addresses usability and comfort issues for users of medium-sized touch displays, though it is incremental as it complements existing dragging methods.
The paper tackled the problem of arm fatigue and skin irritation from prolonged dragging on medium-sized touch displays by introducing TapDrag, an alternative technique using taps at both ends of the drag path, which resulted in faster task completion times for long distances and helped prevent skin irritation.
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.
