摘要：【中文】公开了可由VR/MR系统实现的测距方法和装置，所述系统包括用户保持或穿戴的头戴式显示器(HMD)和附件。测距传感器(例如，超声换能器)可被包括在HMD上以及附件上，并且用于跟踪受约束物理环境诸如房间、体育馆、庭院或场地内或不受约束物理环境中的壁、对象和其他障碍物的距离和相对位置。来自HMD和附件上的传感器的测距信息可用于生成在VR/MR系统中可用于各种目的的用户的环境的3D标测图。除了标测用户的环境之外，测距方法和装置还可用于跟踪附件相对于HMD的相对位置。 【EN】Disclosed are ranging methods and apparatus that may be implemented by a VR/MR system that includes a Head Mounted Display (HMD) and accessories held or worn by a user. Ranging sensors (e.g., ultrasonic transducers) may be included on the HMD and on the accessories and used to track the distance and relative position of walls, objects, and other obstacles within or in a constrained physical environment, such as a room, gym, yard, or field. Ranging information from sensors on the HMD and accessory may be used to generate a 3D map of the user's environment that may be used for various purposes in the VR/MR system. In addition to mapping the user's environment, the ranging methods and devices may also be used to track the relative position of the accessory with respect to the HMD.

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.
