ABSTRACT:
A moveable headrest is mounted on or with respect to a support for supporting a user in viewing images in a standing, seated, or reclining posture. The headrest is for supporting the head of the user in executing head movements with a changing direction-of-view. A display mounted with respect to the user's head provides the images. An actuator can be provided for moving the moveable headrest for a passive user. A sensor can be provided for sensing movements of the moveable headrest, i.e., for sensing said movements from a changing direction. The moveable headrest apparatus may include either or both the actuator and the sensor.
