1. An apparatus for use with at least one display device and at least one image capturing device, the apparatus comprising: a processor; one or more memories coupled to the processor, the one or more memories having stored instructions that configure the apparatus to implement: display logic configurable to output at least one signal suitable for causing a display device to display at least two different selectable regions; interface logic configurable to receive image data from an image capturing device; pose estimation logic operatively coupled to said display logic and said interface logic and configured to determine a first head pose based on a first image and at least a second head pose based on a second image temporally subsequent to said first image, and automatically operatively switch an operative user input focus between said at least two selectable regions based on at least one difference between said first head pose and at least said second head pose; and programmable filter logic operatively coupled to said display logic and said interface logic and configured to filter the second image with respect to the first image, the second image being logically weighted differently than the first image based on an amount of time between a capture of the first image and a capture of the second image.
