Gaze Supported Gestural Computer Interaction: Performance Implications of Training

摘要

Gaze supported non-tactile gestural control uses a combination of gestures based body movements with eyerngaze positioning to provide an input source for a user’s control with a system. Combining body gesturesrnwith eye movements allows for unique computer control methods other than the traditional mouse.rnHowever, research is mixed on the effectiveness of emerging control types, such as gestures and eyetracking,rnwith some showing positive performance outcomes for one or more control aspects butrnperformance detriments in other areas that would prohibit the use of such novel control methods. Onernimportant aspect that is often ignored is familiarity with the control method. Unlike the mouse, users arerntypically unfamiliar with eye and gestures based control methods. In order to truly understand the benefit ofrnnew concepts like gaze supported gestural controls, testing experienced users is necessary. In the currentrnexperiment, participants were trained on the gaze supported gestures system in order to become “experts”rnand achieve similar levels of proficiency with the different control methods to be assessed, to includernmouse, non-gaze and gaze supported gestural controls. Results showed that after as few as five practicernsessions participants were able to perform a simple point and click task as well or even better than mouserncontrol when using gaze supported gestures.
