An input device comprising: a floor engaging member having a floor engaging surface and a longitudinal axis substantially perpendicular to the floor engaging surface; a skeleton support structure having a seat support surface substantially parallel to the floor engaging surface; a bearing disposed between the skeleton support structure configured to allow only relative rotation of the skeleton support structure about the longitudinal axis with respect to the floor; a seat support; a coupling member disposed between the seat support and the seat support surface the coupling member pivotably coupling the seat support surface to the seat support member in a manner which restricts the rotation of seat support with respect to the support skeleton about the longitudinal axis and allows for the rotation of the seat support member in a plurality of directions perpendicular to the longitudinal direction; a first plurality of sensors configured to detect the movement of the seat support with respect the seat support surface about a first and second seat axis and provide a first signal thereof; a motion tracking head mounted display configured to receive a video signal input and having a second plurality of sensors configured to detect the movement of the head mounted display with respect the ground, said second plurality of sensors configured to provide a second signal indicative of the movement of the head mounted display with respect the ground; and a controller configured to receive the first and second signals and selectively adjust the first video signal to display a translational movement of an image at a first time in response to the first signal and selectively adjust the first video signal to display a rotational movement of an image at a second time in response to the second signal. a floor engaging member having a floor engaging surface and a longitudinal axis substantially perpendicular to the floor engaging surface; a skeleton support structure having a seat support surface substantially parallel to the floor engaging surface; a bearing disposed between the skeleton support structure configured to allow only relative rotation of the skeleton support structure about the longitudinal axis with respect to the floor; a seat support; a coupling member disposed between the seat support and the seat support surface the coupling member pivotably coupling the seat support surface to the seat support member in a manner which restricts the rotation of seat support with respect to the support skeleton about the longitudinal axis and allows for the rotation of the seat support member in a plurality of directions perpendicular to the longitudinal direction; a first plurality of sensors configured to detect the movement of the seat support with respect the seat support surface about a first and second seat axis and provide a first signal thereof; a motion tracking head mounted display configured to receive a video signal input and having a second plurality of sensors configured to detect the movement of the head mounted display with respect the ground, said second plurality of sensors configured to provide a second signal indicative of the movement of the head mounted display with respect the ground; and a controller configured to receive the first and second signals and selectively adjust the first video signal to display a translational movement of an image at a first time in response to the first signal and selectively adjust the first video signal to display a rotational movement of an image at a second time in response to the second signal. <EOS>
