Head-mounted display with wireless controller

A method for ensuring that separable components of a head-mounted display apparatus are not physically separated, comprising the steps of

• providing a head-mounted display, the head-mounted display including a viewing area that displays information to a user of the head-mounted display and including a display wireless communication circuit for receiving wireless control signals;
• providing a controller, including a controller wireless communication circuit, wherein the controller controls the information displayed in the head-mounted display by communicating the wireless control signals to the display wireless communication circuit with the controller wireless communication circuit and wherein the controller is physically separate from the head-mounted display;
• providing a distance-monitoring circuit in the controller or the head-mounted display that monitors the distance between the controller and the head-mounted display;
• monitoring the distance between the controller and the head-mounted display;
• and
• initiating a range signal to the user when the distance is greater than a pre-determined distance.

A head-mounted display system, comprising:

• a head-mounted display, the head-mounted display including a viewing area that displays information to a user of the head-mounted display and including a display wireless communication circuit for receiving wireless control signals;
• and
• a plurality of controllers, wherein:
• each controller is physically separate from the head-mounted display and located in a different location;
• and
• each controller, including a controller wireless communication circuit, that controls the information displayed in the head-mounted display in the different location, the information communicated by the wireless control signals from the controller wireless communication circuit to the display wireless communication circuit.
