Abstract:
1. In a wearable head-mounted display (HMD), a computer-implemented method comprising: making a determination that video data from a video camera of the wearable HMD includes a hand gesture of a thumb and forefinger of a particular hand forming a shape of a symbolic right angle in a field of view (FOV) of the wearable HMD, the symbolic right angle having a first leg with a first length corresponding to a length of the thumb projected in the FOV and a second, perpendicular leg with a second length corresponding to a length of the forefinger projected in the FOV; determining that the particular hand is associated with the wearable HMD via analysis of the video data including the hand gesture; determining a closed area in the FOV bounded by a rectangle having a corner at a vertex of the symbolic right angle in the FOV, and having two perpendicular sides coinciding with, and having lengths respectively equal to, the first and second legs of the symbolic right angle; generating an image from the video data of a sub-FOV within the closed area; matching the shape of the symbolic right angle with a predetermined action associated with the image; and executing the predetermined action on a processor of the wearable HMD.
