Methods and devices for determining body pose using fiber optic components

A device comprising:

• a wearable structure configured to couple to a body of a user, the wearable structure comprising:
• a light emitter coupled to a plurality of fiber optic components and configured to transmit a light output to the plurality of fiber optic components;
• an optical switch coupled to the plurality of fiber optic components and having a plurality of inputs and one or more outputs;
• a photo sensor coupled to at least one output of the one or more outputs of the optical switch, wherein the photo sensor is configured to detect a reflected portion of the light output from the light emitter and output a corresponding photo sensor signal;
• control circuitry coupled to the photo sensor and configured to:
• determine a curvature of a respective fiber optic component of the plurality of fiber optic components based on analysis of the corresponding photo sensor signal;
• and
• determine a pose of the user based on the curvature of the respective fiber optic component;
• and
• a power source configured to provide power to the control circuitry, the light emitter, the optical switch, and the photo sensor;
• and
• the plurality of fiber optic components, each fiber optic component of the plurality of fiber optic components comprising a respective set of passive sensors, each passive sensor of the respective set of passive sensors configured to reflect a portion of light transmitted to the fiber optic component.
