Patent number: 8860634Abstract: A head-mountable display (HMD) comprises a frame for mounting on a user's head, a camera mounted on the frame for capturing a view of the user's eyes, a motion detector for detecting motion of the HMD and for generating a motion signal representing a movement of the HMD with respect to time, and a controller. The controller estimates a distance between the user's eyes by capturing a relative separation of the user's eyes from an image of the user's eyes captured by the camera at a start position. The controller processes a motion period of the motion signal, and estimates a displacement of the user's eyes with respect to the frame. The HMD can adjust a relative position at which a first image is displayed to one eye and position at which a second image is displayed to the other eye for an improved viewing experience.Type: GrantFiled: October 11, 2012Date of Patent: October 14, 2014Assignee: Sony Computer Entertainment Europe LimitedInventors: Simon Mark Benson, Ian Henry Bickerstaff
