AI Technical Summary

Technical Problem

Current optical systems in mixed reality (MR) devices, such as those used in virtual reality (VR) and augmented reality (AR), face challenges in accurately localizing users within their environment to correctly position virtual objects relative to real-world elements, particularly in dynamic head-motion scenarios.

Method used

An apparatus worn on the user's head, equipped with a screen, camera system, and processing unit, determines a localizing map based on camera outputs to accurately localize the user by computing a metric indicating the likelihood of successful localization, using co-visibility of reference points and image processing techniques to enhance map quality and user positioning.

Benefits of technology

This solution enables precise localization of users within their environment, improving the accuracy and immersion of MR experiences by ensuring virtual content is correctly aligned with real-world elements, even during dynamic head movements.

Abstract

An apparatus configured to be worn on a head of a user, includes: a screen configured to present graphics to the user; a camera system configured to view an environment in which the user is located; and a processing unit configured to determine a map based at least in part on output(s) from the camera system, wherein the map is configured for use by the processing unit to localize the user with respect to the environment; wherein the processing unit of the apparatus is also configured to obtain a metric indicating a likelihood of success to localize the user using the map, and wherein the processing unit is configured to obtain the metric by computing the metric or by receiving the metric.
