One-Handed Interaction Technique for Single-Touch Gesture Input on Large Smartphones

We propose a one-handed interaction technique using cursor based on touch pressure to enable users to perform various single-touch gestures such as a tap, swipe, drag, and double-tap on unreachable targets. In the proposed technique, cursor mode is started by swiping from the bezel. Touch-down and touch-up events occur at the cursor position when users increase and decrease touch pressure, respectively. Since touch-down and touch-up event triggers are different but easily performed by just adjusting the touch pressure of the thumb from low to high or vice versa, the user can perform single-touch gestures at the cursor position with the thumb. To investigate the performance of the proposed technique, we conducted a pilot study; the results showed that the proposed technique is promising for one-handed interaction technique.
