Abstract: Aspects of the present disclosure are directed to a multi-sensor don/doff detection system for an artificial reality device headset. The multi-sensor don/doff detection system can use a combination of a proximity sensor, an inertial measurement unit (IMU), and an eye tracking/face tracking (ET/FT) unit to make these determinations. However, when both the ET/FT system and proximity sensor system are active, they can have system coexistence issues. Thus, only one of these systems can be used simultaneously. The multi-sensor don/doff detection system can more accurately identify don events by using input from the proximity sensor and the IMU. The multi-sensor don/doff detection system can also more accurately identify doff events by using input from the IMU and either A) the proximity sensor when the ET/FT system is disabled or B) the ET/FT system when the ET/FT system is enabled.

Abstract: Embodiments of the present disclosure provide methods for implementing a mixed reality system with less power. In some examples, a passive state of the mixed reality system can have a GPU render predictable content that does not need to be processed by a CPU. In such examples, the predictable content can be identified and rendered by the GPU while the CPU is in a low-power mode. Accordingly, embodiments of the present disclosure provide benefits not available with conventional techniques because a CPU may consume more power than a corresponding GPU. In some examples, the passive state can take advantage of the fact that predictable content can be identified and rendered without the use of the CPU. In such examples, the passive state can render predictable content that does not need to be processed by the CPU.
