Patent number: 11961331Abstract: A first computing device acquires video data representing a user performing an activity. The first device uses a first pose extraction algorithm to determine a pose of the user within a frame of video data. If the pose is determined to be potentially inaccurate, the user is prompted for authorization to send the frame of video data to a second computing device. If authorization is granted, the second computing device may use a different algorithm to determine a pose of the user and send data indicative of this pose to the first computing device to enable the first computing device to update a score or other output. The second computing device may also use the frame of video data as training data to retrain or modify the first pose extraction algorithm, and may send the modified algorithm to the first computing device for future use.Type: GrantFiled: August 30, 2021Date of Patent: April 16, 2024Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Ido Yerushalmy, Michael Chertok, Sharon Alpert

Patent number: 11861944Abstract: Video output is generated based on first video data that depicts the user performing an activity. Poses of the user during performance of the activity are compared with second video data that depicts an instructor performing the activity. Corresponding poses of the user's body and the instructor's body may be determined through comparison of the first and second video data. The video data is used to determine the rate of motion of the user and to generate video output in which a visual representation of the instructor moves at a rate similar to the that of the user. For example, video output generated based on an instructional fitness video may be synchronized so that movement of the presented instructor matches the rate of movement of the user performing an exercise, improving user comprehension and performance.Type: GrantFiled: September 25, 2019Date of Patent: January 2, 2024Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Ido Yerushalmy, Ianir Ideses, Eli Alshan, Mark Kliger, Liza Potikha, Dotan Kaufman, Sharon Alpert, Eduard Oks, Noam Sorek

Publication number: 20220261574Abstract: Characteristics of a user's movement are evaluated based on performance of activities by a user within a field of view of a camera. Video data representing performance of a series of movements by the user is acquired by the camera. Pose data is determined based on the video data, the pose data representing positions of the user's body while performing the movements. The pose data is compared to a set of existing videos that correspond to known errors to identify errors performed by the user. The errors may be used to generate scores for various characteristics of the user's movement. Based on the errors, exercises or other activities to improve the movement of the user may be determined and included in an output presented to the user.Type: ApplicationFiled: February 16, 2021Publication date: August 18, 2022Inventors: EDUARD OKS, RIDGE CARPENTER, LAMARR SMITH, CLAIRE MCGOWAN, ELIZABETH REISMAN, IANIR IDESES, ELI ALSHAN, MARK KLIGER, MATAN GOLDMAN, LIZA POTIKHA, IDO YERUSHALMY, DOTAN KAUFMAN, GUY ADAM, OMER MEIR, LIOR FRITZ, IMRY KISSOS, GEORGY MELAMED, ERAN BORENSTEIN, SHARON ALPERT, NOAM SOREK
