The Hold-and-Move Gesture for Multi-touch Interfaces

摘要

We present the two-finger gesture hold-and-move as an alternative to the disruptive long-tap which utilizes dwell times for switching from panning to object dragging mode in touch interfaces. We make use of a second finger for object selection and manipulation while workspace panning is operated with the first finger. Since both operations can be performed simultaneously, the cumbersome and hard-to-control autoscrolling function is no longer needed when dragging an object beyond the currently visible viewport. Single-finger panning and pinch zooming still work as expected. A user study revealed that hold-and-move enables faster object dragging than the conventional dwell-time approach and that it is preferred by most users.
