  • Patent number: 11694360
    Abstract: A processing device receives, from a three-dimensional (3D) motion capture system, initial data representing an initial orientation of a subject user's body in an initial position. The processing device further receives x-ray data representing at least the portion of the subject user's body in the initial position. The processing device determines an actual orientation of at least one bone or joint from the portion of the subject user's body in the initial position as represented in the x-ray data and calibrates the initial orientation of the 3D motion capture system to reflect the actual orientation of the at least one bone or joint in the initial position.

  • Publication number: 20220260608
    Abstract: A processing device initializes an inertial motion capture sensor affixed to a segment of a subject user's body in a detection mode of operation and measures at least one of angular speed or linear acceleration of the segment of the subject user's body using the inertial motion capture sensor in the detection mode of operation. Responsive to the at least one of the angular speed or linear acceleration satisfying a threshold criterion, the processing device switches the inertial motion capture sensor from the detection mode of operation to a capture mode of operation, captures three-dimensional (3D) motion capture data associated with movement of the segment of the subject user's body, and stores the 3D motion capture data in a data store of the inertial motion capture sensor for subsequent retrieval and analysis by a separate computing device.

  • Patent number: 11386806
    Abstract: A processing device receives three dimensional (3D) motion capture data corresponding to a subject user performing a physical activity and receives attribute data associated with the subject user. The processing device determines a personalized reference data set for the subject user based on 3D motion capture data associated with a group of users performing the physical activity, wherein each user from the group of users shares at least a portion of the first attribute data with the subject user. The processing device provides the personalized reference data set as an input to a trained machine learning model and obtains an output of the trained machine learning model, wherein the output comprises a recommendation for the subject user pertaining to improvement of the physical activity.

  • Patent number: 11210855
    Abstract: A processing device receive a two dimensional (2D) video recording of a subject user performing a physical activity and provides a three dimensional (3D) visualization comprising a virtual avatar performing the physical activity. The processing device causes display of the 3D visualization comprising the virtual avatar at a first key point in performing the physical activity, receives first user input to advance the 2D video recording to a first position corresponding the first key point, and receives second user input comprising a first synchronization command. In response, the processing device generates a first synchronization marker to indicate the first position in the 2D video recording corresponding to the first key point.

  • Publication number: 20200356765
    Abstract: A processing device provides a plurality of motion capture sensors affixed to different portions of a subject and establishes, without using a magnetometer, a common reference frame for the plurality of motion capture sensors. The processing device further receives, from the plurality of motion capture sensors, 3D motion capture data corresponding to a movement of the subject and interprets, using the common reference frame, the 3D motion capture data from the plurality of motion capture sensors to represent the movement of the subject.

  • Publication number: 20200205900
    Abstract: A processing device receives first continuous motion capture data representing dynamic motion of at least one of a bone or a joint of the subject user while performing a physical movement. The processing device further generates, based on the continuous motion capture data, a three dimensional (3D) visualization comprising a virtual avatar performing the physical movement and provides a visualization of a surgical implant overlaid on the virtual avatar. The processing device receives input comprising an adjustment to an orientation of the visualization of the surgical implant relative to the at least one of the bone or the joint and determines whether the orientation of the visualization of the surgical implant satisfies a condition pertaining to the subject user performing the physical movement.
