摘要： A head-mounted device is provided that includes one or more cameras configured to acquire a raw video feed and one or more displays configured to present a passthrough video feed to a user. Generation of the passthrough video feed can involve processing the raw video feed using an image signal processor and auxiliary compute blocks. One or more of the auxiliary compute blocks can be bypassed in response to detecting one or more failures associated with the auxiliary compute blocks. Configured and operated in this way, the head-mounted device can fall back to a more reliable passthrough video feed without having to power cycle the head-mounted device when a failure occurs.

摘要： An electronic device is provided that includes at least one image sensor for acquiring a video feed and one or more displays for presenting a passthrough video feed to a user. The electronic device can include a hierarchical failure detection scheme for detecting critical failures on the device. The hierarchical failure detection scheme may include monitoring a condition of a first subsystem with a second subsystem, monitoring a condition of the second subsystem with a third subsystem, monitoring a condition of the third subsystem with a fourth subsystem, and so on. The displays can operate in a first video passthrough mode or a second video passthrough mode based on the condition of the first subsystem as monitored by the second subsystem, the condition of the second subsystem as monitored by the third subsystem, and/or the condition of the third subsystem as monitored by the fourth subsystem.

摘要： An electronic device may include software and hardware subsystems that are centrally controlled by a user experience manager. The user experience manager can identify a current user context and enforce a corresponding power and performance policy for the various subsystems that is optimized for the current user context. The user experience manager can provide a set of restrictions at the launch of a user experience, can allow the various subsystems to vary their dynamic behavior based on current operating conditions as long as the dynamic adjustments do not violate the restrictions, and can perform a series of thermal mitigation operations as the internal temperature of the electronic device varies. The centralized user experience manager can also be configured to predict a user context based on monitored states of the subsystems and monitored application usage on the electronic device.
