Monitoring activity of a user in locomotion on foot

摘要

A device supported by a user while the user is in locomotion on foot during an outing to automatically measure amounts of time taken by the user to complete respective distance intervals. During the outing, data representing the automatically measured amounts of time may be automatically stored in memory of the device. During the outing, the device may display at least one of an average pace of the user since a most recently completed distance interval, an average speed of the user since the most recently completed distance interval, and a projected time to complete a current distance interval based on monitored performance since the most recently completed distance interval. The device may determine a remaining distance to be traveled to complete a specified goal distance for the outing and a calculated fraction of the specified goal distance for the outing.

主权项

1. A unitary apparatus configured to be worn by a user, comprising:
a unitary body, further comprising:
a processor;a user interface;a sensor in operative communication with the processor, and configured to capture motion data of the user indicative of a heel-strike event and a toe-off event; anda non-transitory computer-readable medium comprising computer-executable instructions that when executed by the processor perform at least:
receiving the motion data from the sensor;identifying the heel-strike event and the toe-off event from the motion data;calculating a foot contact time between the heel-strike event and the toe-off event during a motion of the user;
calculating, from the motion data, an estimated heart rate of the user as a stored fitness index for the user divided by the foot contact time of the user; andgenerating a graphical representation of the estimated heart rate and outputting the graphical representation to the user interface.
