AI Technical Summary

Technical Problem

Existing head-mounted devices, such as AR and VR devices, suffer from inconsistent audio output due to differences in the anatomical features of users' ears and heads, as well as inconsistencies in device compatibility, which affects the user experience.

Method used

By receiving images of the user's ears, a machine learning model is used to generate a personalized equalization filter, which adjusts the acoustic parameters of the audio output to match the target response of the user's ears. The personalized equalization filter is then attached to the user's profile.

Benefits of technology

It improves the personalization and adaptability of audio output, reduces audio output variations caused by differences between users and devices, and enhances the user's audio experience.

Abstract

A method of generating a personalized audio output response for a head-mounted device using a machine learning model. One or more images of a portion of a user's head are received, the one or more images including at least the user's ears. One or more features describing the user's ears are identified based on the one or more images. The features are input to a model, and the model is configured to determine an audio output response for the user based on the identified one or more features. The audio output response describes one or more acoustic parameters perceived by the user. A personalized audio output response is generated for the user based on the audio output response, the personalized audio output response configured to adjust one or more acoustic parameters of audio content provided to the user by the head-mounted device.
