Controlling a head-mounted display system in low power situations

Abstract:

The present disclosure relates to head-mounted displays (HMDs) and HMD controllers and to managing low power situations. As the HMD and controller are operational, the HMD monitors the energy level of the batteries. If the HMD detects that a battery energy level is below a first threshold, the HMD sends a low battery command to a developer application. The low battery command causes the developer application to enter a low battery mode in which it performs operations that encourage the user to charge the battery. If the energy level of the battery continues to decrease, the HMD may detect the battery energy is below a second threshold. As a result, the HMD and controller enter into a pass-through mode. In a pass-through mode the HMD projects a representation of an operating environment of the HMD in a display of the HMD.
