Abstract
An image display method and system in which exertion of a user's viewpoint orienting muscle groups is yoked to sensors measuring displacement and/or force to provide feedback information for control of a virtual-world without requiring full physical-motion by the user. The yoked muscle exertion is mapped to the rate and direction of movement in the virtual-world. Preferably, force exerted by, and/or rotation or translation of, the yoking device in one direction in response to exertion of the muscle groups is mapped to virtual-motion in a corresponding direction in the virtual-world. Due to the fluidity of the human vertebral column, the invention effectively yokes rotational movement of a human's viewpoint orienting muscles to virtual movement in a virtual-world without the disadvantages of a head-mounted display. To orient toward an area-of-interest in a leftward portion of a virtual-world, the user simply and naturally activates muscles that would be used to orient left in the physical world. At the same time, the effect of virtual-motion as the displayed image viewpoint moves is compelling because while the muscles are contracting, special sensory information is sent to the brai…
