<p>A head-mountable display comprises a frame which is configured to be mounted on a user's head, a camera (600) mounted on the frame for capturing a view of the user's eyes, a motion detector (610) for detecting motion of the head mountable display device and for generating a motion signal representing a movement of the head mountable display with respect to time, and a controller. The controller is configured to estimate a distance Dr 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, to process a motion period of the motion signal corresponding to a process in which the user moves the head mountable display from the start position (900) to dispose the head mountable display on the user's head at an end position, and to estimate a displacement of the user's eyes with respect to the frame by determining a distance Dx from the start position of the head mountable display at which the image of the user's eyes was captured to the end position in which the head mountable display is disposed on the user's head. The head mountable display can be arranged therefore to adjust a relative position at which a first image is displayed to one of the user's eyes and position at which a second image is displayed to the other of the user's eyes in accordance with the estimated distance between the user's eyes so as to provide an improved viewing experience.</p> |
