Abstract: Techniques are described for collecting sensor data associated with a wheelchair and, based on the sensor data, determining metric(s) for a user of the wheelchair. Sensor(s) attached to, or in proximity to, the wheelchair may collect sensor data describing the wheelchair and/or its component(s), such as location, velocity, acceleration, direction of movement, orientations (e.g., pitch, yaw, roll), angular velocity of wheels, angular acceleration of wheels, and so forth. The sensor data may be analyzed to determine (e.g., fitness) metrics such as a caloric burn rate, a metabolic burn rate, and/or power expenditure of the user while the user is employing the wheelchair to exercise or otherwise move. The metric(s) and/or sensor data may be presented to the user through a user interface on a smartphone, tablet computer, wearable computer, or other device, to enable the user to monitor fitness metric(s) during use of the wheelchair.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for establishing a communication connection between a biowearable embedded circuit and a computing device associated with a user, wherein the biowearable embedded circuit is mounted to the user; obtaining atmospheric, motion, communication, and/or biometric data associated with the user; and providing the atmospheric, motion, communication, and/or biometric data to the computing device.
