Having spent countless sessions interacting with a (by today's standards) medium sized touch display (~30 to 50 inches), we found that traditional dragging gestures didn't live up to our ergonomic expectations. Prolonged use sometimes led to arm fatigue and on more than one occasion did we experience skin irritation. This would even lead to trying to avoid having to drag something long distance, just due to the potential discomfort involved. Although the day has yet to arrive when these larger touch devices are ubiquitous, they're becoming increasingly more common. They already exist in shared work environments, public installations, malls, or even as part of performance instruments.
Given this context, it seemed feasible to come up with an alternative to traditional dragging. Enter, TapDrag.
