Abstract:

The embodiments of the present disclosure are capable of capturing a user's movement using inertial measurement units (IMUs) that are embedded in, or otherwise attached to, clothing. In one embodiment, a wearable system for capturing a user's bodily movements includes a wearable item mechanically coupled to an inertial measurement unit (IMU). The wearable item, when worn by a user, positions the IMU proximate to a body part of the user. The system further includes a processor communicatively coupled to the IMU and configured to receive the sensor data from the IMU, generate movement data based on the sensor data, and transmit the movement data to a device. The device includes a processor configured to receive the movement data, generate a kinematic chain model of the user, the model representing positions and orientations of one or more joints of the user at a given time, modify the kinematic chain model based on the movement data, determine a force experienced at a joint of the user using the kinematic chain model, and record the kinematic chain model and the force over a period of time.
