The keeper's note

Mapping real-world features into virtual/AR space, with wireless-power signal.

Abstract

Embodiments provide for an augmented reality (AR) system able to track the movement of real-world objects and apply that movement to virtual objects. The AR system includes a radio configured to receive first sensor data from a sensor attached to a first physical object in physical space. The AR system further includes a processor configured to determine when a physical object changes from a first state to a second state object based on the first sensor data, and update an environmental map based on the change from the first state to the second state of the first physical object.

Background

BACKGROUND

In many instances, one or more mapping algorithms are utilized to generate and/or update environmental maps utilized by an augmented reality (AR) system. The mapping algorithms generate virtual depictions of real-world objects within the environmental maps. One example mapping algorithm is a simultaneous localization and mapping (SLAM) algorithm. However, the mapping algorithms are often unable to properly map moving real-world objects, resulting in artifacts and/or misrepresented real-world objects. For example, an AR object may not be moved or moved too slowly in response to movement of a corresponding real-world object, resulting in a poor user experience. In some instances, tracking system may be utilized to track the movement of real-world objects and aid in updating environmental maps. However, these tracking systems are expensive and complex, limiting the possible applications in which such tracking systems may be utilized. SUMMARY

In one embodiment, a method for updating an environmental map of an augmented reality (AR) system comprises receiving first sensor data from a sensor attached to a first physical object in physical space and determining a change from a first state to a second state of the first physical object based on the first sensor data. The method further comprises updating the environmental map based on the change from the first state to the second state of the first physical object, and updating a presentation based on the upd
