Publication number: 20240061243Abstract: A sensory eyewear system for a mixed reality device can facilitate user's interactions with the other people or with the environment. As one example, the sensory eyewear system can recognize and interpret a sign language, and present the translated information to a user of the mixed reality device. The wearable system can also recognize text in the user's environment, modify the text (e.g., by changing the content or display characteristics of the text), and render the modified text to occlude the original text.Type: ApplicationFiled: July 24, 2023Publication date: February 22, 2024Inventors: Eric Browy, Michael Janusz WOODS, Andrew Rabinovich

Patent number: 11836284Abstract: Head-mounted augmented reality (AR) devices can track pose of a wearer's head or pose of a hand-held user input device to enable wearer interaction in a three-dimensional AR environment. A pose sensor (e.g., an inertial measurement unit) in the user input device can provide data on pose (e.g., position or orientation) of the user input device. An electromagnetic (EM) tracking system can also provide pose data. For example, the handheld user input device can include an EM emitter that generates an EM field, and the head-mounted AR device can include an EM sensor that senses the EM field. The AR device can combine the output of the pose sensor and the EM tracking system to reduce drift in the estimated pose of the user input device or to transform the pose into a world coordinate system used by the AR device. The AR device can utilize a Kalman filter to combine the output of the pose sensor and the EM tracking system.Type: GrantFiled: December 1, 2022Date of Patent: December 5, 2023Inventors: Sheng Wan, Michael Janusz Woods

Patent number: 11709544Abstract: Head-mounted augmented reality (AR) devices can track pose of a wearer's head to provide a three-dimensional virtual representation of objects in the wearer's environment. An electromagnetic (EM) tracking system can track head or body pose. A handheld user input device can include an EM emitter that generates an EM field, and the head-mounted AR device can include an EM sensor that senses the EM field. EM information from the sensor can be analyzed to determine location and/or orientation of the sensor and thereby the wearer's pose. An improved or optimized pose can be provided by reverse-estimating a reverse EM measurement matrix and optimizing the pose based on a comparison between the reverse EM measurement matrix and an EM measurement matrix measured by the EM sensor.Type: GrantFiled: December 29, 2020Date of Patent: July 25, 2023Assignee: Magic Leap, Inc.Inventor: Michael Janusz Woods
