Two new Apple HMD Inventions cover Directional Audio Detection and Dust Particle Removal Systems
Today the US Patent & Trademark Office published a pair of patent applications from Apple relating to their Head Mounted Display Device project. The first invention covers an audio-based feedback system. Multiple microphones distributed across the head-mountable device will provide the user with directional audio detection. Apple's second invention covers a system that could shake loose floating particle of dust in the lens system that are interfering with the user's view of VR content and/or real-world events.
In Apple's patent background they note that a head-mountable device (HMD) can be worn by a user to display visual information within the field-of-view of the user. The head-mountable device can be used as a virtual reality (VR) system, an augmented reality (AR) system, and/or a mixed reality (MR) system.
