WRIST-BASED SPEED AND DISTANCE MONITORING
First Claim
1. A wrist-worn mobile electronic device configured to be worn about a user'"'"'s wrist, the device comprising:
- a motion sensor configured to sense motion of the user'"'"'s wrist and generate acceleration data;
a position determining module operable to receive one or more signals to determine a current geographic location of the mobile electronic device;
a non-transitory memory configured to store at least portions of the acceleration data and a scale factor corresponding to a plurality of average acceleration points; and
a processor coupled with the memory, the processor operable to—
determine, based on the acceleration data, a cadence for the user,determine, based on the acceleration data, an average acceleration of the user'"'"'s wrist,select the scale factor using the determined average acceleration, andcompute a current speed for the mobile electronic device based on the cadence, determined average acceleration and selected scale factor.
