SPATIAL AUDIO FOR THREE-DIMENSIONAL DATA SETS

A head mounted display (HMD) device is provided that includes a display, a position and orientation sensor, and speakers. The HMD device includes a processor configured to receive map data of a three-dimensional environment, receive a three-dimensional data set, detect a predefined feature in the three-dimensional data set, place a spatial audio emitter anchor in the three-dimensional environmentin a location where the feature was detected, the spatial audio emitter having an emitter boundary, determine a current location of a user in the virtual environment based on a signal from the sensor,display the map data of the three-dimensional environment with a graphical representation of the three-dimensional data set based on the determined current location of the user, and responsive to determining that the location of the user is outside of the boundary, play the spatial audio emitter in a spatial audio mode via the near-ear speakers. 提供了一种头戴式显示(HMD)设备，其包括显示器、位置和定向传感器以及扬声器。HMD设备包括处理器，该处理器被配置成：接收三维环境的地图数据；接收三维数据
