Exploring Two-handed Indirect Multi-touch Input for a Docking Task
In Proceedings of the International Working Conference on Advanced Visual Interfaces (AVI '16). Bari, Italy, June 7 - 10, 2016. ACM, New York, NY, USA.

To better understand the characteristics of two-handed indirect multi-touch input, we conducted a docking task experiment that asked participants to align rectangles with other rectangles using one-finger dragging as well as twofinger pinch-to-zoom and rotation gestures in three conditions: (1) using the dominant hand only, (2) using the nondominant hand only and (3) using both hands simultaneously. Our experiment was based on a conventional desktop computer setup, extended with a pair of tablet devices that were placed left and right of the keyboard. Most importantly, the results indicate that the two-handed condition yields the fastest results and the participants actions exhibited Guiards well-known principles of asymmetric bimanualinteraction. Further, we observed that the performance of the non-dominant hand was on par with the dominant hand, suggesting that designers of two-handed multi-touch input techniques can assume a comparable level of dexterity for both hands.
