Transture: Continuing a Touch Gesture on a Small Screen into the Air.

In order to cope with usability problems of touch gestures caused by the small touchscreen size of a smartwatch, we propose a concept, named Transture, which relaxes the spatial constraints of touch gestures on the small screen by allowing them to continue beyond the screen border into the air. We designed three Transture examples for panning, zooming, and menu. We conducted a preliminary user study to verify its feasibility and collect design issues for improving Transture designs for future work.
