Problems solved by technology

However, all spatialized audio systems (with or without VR / AR / MR systems) can lead to cognitive dissonance for rapid pose changes, since all spatialized audio systems include virtual positions relative to the user / listener and directional virtual sound source

Abstract

A spatialized audio system includes sensors for detecting head poses of a listener. The system also includes a processor for rendering the audio data in the first stage and the second stage. The first stage includes rendering first audio data corresponding to a first plurality of sources into second audio data corresponding to a second plurality of sources. The second stage includes rendering the second audio data corresponding to the second plurality of sources into third audio data corresponding to the third plurality of sources based on the detected head pose of the listener. The second plurality of sources consists of fewer sources than the first plurality of sources.

Description

technical field [0001] The present disclosure relates to virtual reality, augmented reality and / or mixed reality systems with spatialized audio systems, and methods for generating virtual reality, augmented reality and / or mixed reality experiences including spatialized audio using the systems. Background technique [0002] Modern computing and display technologies have facilitated the development of mixed reality systems for so-called "mixed reality (MR)", "virtual reality (VR)" and / or "augmented reality (AR)" experiences. This can be done by presenting computer-generated images to the user via a head-mounted display. This imagery creates a sensory experience that immerses the user in a simulated environment. VR scenes typically involve the presentation of digital or virtual image information opaque to actual real-world visual input. [0003] AR systems often supplement real-world environments with simulated elements. For example, AR systems can provide users with a view ...
