Abstract
Modalities such as pen and touch are associated with direct input but can also be used for indirect input. We propose to combine the two modes for direct-indirect input modulated by gaze. We introduce gaze-shifting as a novel mechanism for switching the input mode based on the alignment of manual input and the user's visual attention. Input in the user's area of attention results in direct manipulation whereas input offset from the user's gaze is redirected to the visual target. The technique is generic and can be used in the same manner with different input modalities. We show how gaze-shifting enables novel direct-indirect techniques with pen, touch, and combinations of pen and touch input.
