Treadmill providing multiple axis displacement of the moving surface

A treadmill exercise apparatus, comprising:

• a substantially circular deck platform comprising a longitudinal axis, a lateral axis, and a vertical axis;
• a support platform supporting the deck platform;
• a tread belt operably connected to a drive motor, the drive motor causing continuous movement of the belt along the longitudinal axis to provide a substantially rectangular moving deck on an upper surface of the deck platform;
• a first plurality of anchor points on the deck platform positioned laterally to the moving deck and configured and arranged such that the first plurality of anchor points remain in a fixed orientation relative to the moving deck;
• a second plurality of anchor points on the support platform such that the second plurality of anchor points are on non-rotating/non-tilting portions of the treadmill exercise apparatus;
• a first actuator configured to introduce yaw motion of the deck platform such that the longitudinal axis of the deck platform rotates about the vertical axis and the moving deck is thereby displaced relative to the support platform;
• a second actuator configured to introduce roll motion of the deck platform such that the lateral axis of the deck platform rotates about the longitudinal axis and the moving deck is thereby displaced relative to the support platform;
• and
• a display system configured to project visual cues in the form of visible light onto a ground surrounding the treadmill exercise apparatus,
• wherein the first and the second actuators are configured and arranged such that the deck platform accommodates displacement of the moving deck about the vertical axis and the longitudinal axis simultaneously.
