Abstract: A system having sensor modules and a computing device. Each sensor module has an inertial measurement unit configured to track its orientation. In a kinematic chain, multiple rigid parts of a user are connected via joints. At least one rigid part is not independently tracked using sensor modules. The computing device computes the estimates of the orientation of the rigid part, separately using an artificial neural network model or using assumed orientation relations. During a sequence of actions performed by the user, orientation estimates produced by one technique can be more accurate than another technique at some time instances, but less accurate at other time instances. An artificial neural network is trained to classify the accuracy the estimates and/or to combine the estimates to provide improved orientation estimates for the duration of the sequence of actions.

Abstract: A system including: a plurality of sensor modules having inertial measurement units and attached to different parts of a user (e.g., head, hands, arms) to measure their orientations; a plurality of optical marks attached to the user; a camera attached to the user; and a computing device configured to correct an accumulated error by detecting the optical marks in an image generated by the camera and identifying mismatches in directions of the optical marks (or the sensors, or parts of the users) as measured and/or calculated based on the image and the corresponding directions of the optical marks (or the sensors, or parts of the users) as measured and/or calculated from the orientation measurements generated by the sensor modules.

Abstract: A system to track orientations of parts of a user based on both images and inertial measurement units (IMUs). For example, the system receives images showing a portion of the user wearing sensor modules. The system receives a first set of orientation measurements generated by the sensor modules attached to some parts of the user. The system determines the second set of orientation measurements of one or more features of the portion of the user from the images. The system provides the first set of orientation measurements and the second set of orientation measurements as input to an artificial neural network that is configured to predict orientation measurements of the one or more other parts of the user that would be measured by additional sensor modules if the additional sensor modules were to be attached to the other parts of the user.

Abstract: A computing system having a plurality of sensor modules configured to be attached to a user. At least a first subset of the sensor modules each has an inertial measurement unit; and at least a second subset of the sensor modules each has one or more biological response sensors. The computing system further includes a computing device in communication with the sensor modules. The computing device is configured to control an application based on motion data of the user measured by inertial measurement units in the sensor modules and biological responses determined by sensor modules.

Abstract: A system to extrapolate from motion states measured for past time instances during a user movement to predict motion states at a subsequent time instance at a display of a virtual object corresponding to the user movement. The prediction can be used to render the display and reduce or eliminate the lag between user action and corresponding action of the virtual object. An artificial neural network can be trained to improve the prediction accuracy based on patterns of user movements in the use of the application displaying virtual reality, augmented reality, mixed reality, and/or extended reality.
