1. A computing device operatively coupled to a display device and an image capturing device, the computing device comprising:

  • display logic configured to output at least one signal suitable for causing the display device to display at least two different selectable regions;

    interface logic configured to receive image data from the image capturing device; and

    pose estimation logic configured to determine a first head pose based on a first image and a second head pose based on a second image temporally subsequent to the first image, switch an operative user input focus between the at least two selectable regions based on at least one difference between the first head pose and the second head pose, and refine the operative user input focus to a previous position of the operative user input focus in a selectable region when the operative user input focus switches to the selectable region.
