Technique for directing audio in augmented reality system
First Claim
1. A hearing aid for use by an end user, comprising:
- at least one sensor configured for detecting a focus of the end user on a real sound source;
an adaptive microphone assembly configured for converting sounds into electrical signals;
at least one speaker configured for converting the electrical signals to sounds for perception by the end user; and
a control subsystem configured for modifying, based onthe detected focus of the end user,a direction of a greatest sensitivity of the adaptive microphone assembly, anda distance of the greatest sensitivity of the adaptive microphone assembly,wherein the control subsystem is configured for processing the electrical signals to compare characteristics of a first sound originating from the real sound source to characteristics of a second sound originating from a different source, emphasizing sounds having the same type of characteristics as the characteristics of the first sound, and deemphasizing sounds having the same type of characteristics as the second sound.

Abstract
A hearing aid comprises a sensor configured for detecting a focus of an end user on a real sound source, a microphone assembly configured for converting sounds into electrical signals, a speaker configured for converting the electrical signals into sounds, and a control subsystem configured for modifying the direction and/or distance of a greatest sensitivity of the microphone assembly based on detected focus. A virtual image generation system comprises memory storing a three-dimensional scene, a sensor configured for detecting a focus of the end user on a sound source, a speaker configured for conveying sounds to the end user, and a control subsystem configured for causing the speaker to preferentially convey a sound originating from the sound source in response to detection of the focus, and for rendering image frames of the scene, and a display subsystem configured for sequentially displaying the image frames to the end user.
