Gaze-Hand Alignment

Gaze and freehand gestures suit Augmented Reality as users can interact with objects at a distance without need for separate input device. We propose Gaze-Hand Alignment novel multimodal selection principle, defined by concurrent use of both gaze hand pointing alignment their on an object trigger. naturally precedes manual action is leveraged pre-selection, crossing pre-selected target completes the selection. demonstrate principle in two techniques, Gaze&Finger direct finger raised into line sight, Gaze&Hand indirect cursor relative movement. In menu experiment, we evaluate techniques comparison Gaze&Pinch hands-only baseline. The study showed gaze-assisted to outperform input, gives insight trade-offs combining or indirect, spatial semantic gestures.
