Methods and systems for providing a reliable hands-free interface between a user and a computing device are presented herein. The interface system includes a gaze tracking system, display system, and head motion tracking system all attached to a frame that is mountable to the head of a user. Eye movements are tracked to determine when the gaze of a user has settled on a particular image displayed by the display system. After a fixed gaze has been identified, it is determined whether the user is moving his/her head in a confirmatory head gesture. The user selection is verified by determining whether the gaze of the user remains fixed to the selected image while executing the confirmatory gesture. This ensures that the gaze of the user remains focused on the selected image projected by the display, rather than an object in the surrounding environment.
