Gaze swipe selection
Methods for enabling hands-free selection of virtual objects are described. In some embodiments, a gaze swipe gesture may be used to select a virtual object. The gaze swipe gesture may involve an end user of a head-mounted display device (HMD) performing head movements that are tracked by the HMD to detect whether a virtual pointer controlled by the end user has swiped across two or more edges of the virtual object. In some cases, the gaze swipe gesture may comprise the end user using their head movements to move the virtual pointer through two edges of the virtual object while the end user gazes at the virtual object. In response to detecting the gaze swipe gesture, the HMD may determine a second virtual object to be displayed on the HMD based on a speed of the gaze swipe gesture and a size of the virtual object.
