Patent attributes
Disclosed herein are embodiments of an athletic coaching system that includes at least one inward-facing head-mounted thermal camera (CAM) and a computer. Each CAM from among the at least one CAM is configured to take thermal measurements of a region below the nostrils (denoted THRBN) of a user. THRBN are indicative of an exhale stream of the user (e.g., an exhale stream from a nostril and/or from the mouth). The computer is configured to: receive measurements of movements (Mmove) involving the user; generate, based on THRBN and Mmove, a coaching indication; and present, via a user interface, the coaching indication to the user. In one example, the coaching indication is indicative of a change the user should make to one or more of the following: cadence of movements, stride length, breathing rate, breathing type (mouth or nasal), and duration of exhales.
