High dynamic range for head-mounted display device

A technique for adjusting the brightness values of images to be displayed on a stereoscopic head mounted display is provided herein. This technique improves the perceived dynamic range of the head mounted display by dynamically adjusting the pixel intensities (also known generally as “exposure”) of the images presented on the head mounted display based on a detected gaze direction. The head mounted display includes an eye tracker that is able to sense the gaze directions of the eyes. The eye tracker, head mounted display, or a processor of a computer system receives this information, determines an intersection point of the eye gaze and a screen within the head mounted display and identifies a gaze area around this intersection point. Using this gaze area, the processing system adjusts the pixel intensities of an image displayed on the screen based on the intensities of the pixels within the gaze area.

Motion windows are generated from a query activity sequence. For each of the motion windows in the query activity sequence, a corresponding motion window in the reference activity sequence is found. One or more difference calculations are performed between the motion windows of the query activity sequence and the corresponding motion windows in the reference activity sequence based on at least one criterion associated with physical meaning. Abnormality of the motion windows is determined based on the one or more difference calculations. A standardized evaluation result of the query activity sequence is output based on the detected abnormal motion windows in the query activity sequence.
