Abstract: Techniques are described for backlighting electronic headset display panels. The method can include emitting light from a light source. The light can be transmitted from the light source via a light transmitting element to illuminate a light guide plate that is located remotely from the light source. The light guide plate can illuminate a display panel that is located remotely from the light source. A photodiode can detect a characteristic of the light that is transmitted by the light transmitting element at a location proximate the display panel and remote from the light source. One or more processors can determine a power level of the light source that is based at least in part on the characteristic detected by the photodiode.

Abstract: A system for adjusting an interpupillary distance and an eye relief distance of a headset. The system can determine an interpupillary distance of a user and an eye relief distance of the user. The system can cause an adjustment assembly to adjust a first distance between the first lens and the second lens along a first axis based at least in part on the interpupillary distance and cause the adjustment assembly to adjust the optical assembly a second distance along a second axis that is orthogonal to the first axis based at least in part on the eye relief distance.

Abstract: A head mounted display (HMD) includes a set of one or more lenses defining an optical axis, a display configured to project light through the set of the one or more lenses, a voice coil actuator coupled with the display and configured to move the display along the optical axis, and a first guide that is separate from the first voice coil actuator and coupled with the first display to guide the movement of the first display. The HMD additionally includes a set of one or more position sensors configured to determine a position of the display long the optical axis and an electronic controller configured to receive information identifying a reference position of the display along the optical axis and generate one or more electrical signals for initiating a movement of the first display toward the first reference point along the optical axis.
