Abstract
Biometric monitoring devices, including various technologies that may be implemented in such devices, are discussed herein. Additionally, techniques for utilizing gyroscopes in biometric monitoring devices are provided. Such techniques may, in some implementations, involve obtaining swimming metrics regarding stroke cycle count, lap count, and stroke type. Such techniques may also, in some implementations, involve obtaining performance metrics for bicycling activities.
Claims28
A biometric monitoring system comprising:
- a housing configured to be worn on a person's forearm or insertable into an accessory worn on the person's forearm;
- a gyroscopic motion sensor located in the housing;
- a memory;
- and
- control logic, wherein:
- the control logic, the memory, and the gyroscopic motion sensor are communicatively connected with one another, and
- the control logic is configured to:
- a) obtain angular motion data from the gyroscopic motion sensor,
- b) determine each time a swim stroke is indicated, at least in part, by the angular motion data, and
- c) alter stored information pertaining to a number of swim strokes in the memory responsive to (b).
A computer-readable, non-transitory storage medium storing computer-executable instructions for controlling one or more processors to:
- a) obtain angular motion data from a gyroscopic motion sensor located in a housing worn on a person's forearm,
- b) determine each time a swim stroke is indicated, at least in part, by the angular motion data, and
- c) alter stored information pertaining to a number of swim strokes in a memory responsive to (b).
