摘要：【中文】本发明题为“显示系统”。本发明提供了一种显示系统，所述显示系统包括头戴式显示单元和唤醒控制系统。所述头戴式显示单元向用户提供虚拟内容并且可在低功率状态和高功率状态下操作，所述高功率状态比所述低功率状态消耗更多的功率以向所述用户提供所述虚拟内容。所述唤醒控制系统确定何时在所述高功率状态下操作。所述唤醒控制系统可评估具有低功率的第一唤醒标准，在满足所述第一唤醒标准时评估具有比所述第一唤醒标准更高的功率的第二唤醒标准，并且在满足所述第二唤醒标准时使所述头戴式显示单元在所述高功率状态下操作。 【EN】The invention provides a display system. The invention provides a display system, which comprises a head-mounted display unit and a wake-up control system. The head-mounted display unit provides virtual content to a user and is operable in a low-power state and a high-power state that consumes more power than the low-power state to provide the virtual content to the user. The wake-up control system determines when to operate in the high power state. The wake-up control system may evaluate a first wake-up criterion having a low power, evaluate a second wake-up criterion having a higher power than the first wake-up criterion when the first wake-up criterion is satisfied, and cause the head-mounted display unit to operate in the high-power state when the second wake-up criterion is satisfied.
