Method and device for measuring amount of user physical activity

An electronic device comprising:

• a sensor;
• and
• a measurement module configured to:
• count an amount of physical activity using a sensor value of the sensor, to store count information comprising a first count start time, a first count end time, and a first amount of physical activity counted between the first count start time and the first count end time in a memory,
• receive second count information comprising a second count start time, a second count end time, and a second amount of physical activity from at least one other device when the electronic device is connected with the at least one other device through short range communication,
• determine an integrated amount of physical activity using the second count information and the first count information, to change an entire amount of physical activity corresponding to the electronic device according to the integrated amount of physical activity,
• transmit the integrated amount of physical activity to the at least one other device, and
• perform synchronization between the electronic device and the at least one other device of the amount of physical activity,
• wherein the measurement module is further configured to determine that the integrated amount of physical activity is based on a priority of the electronic device and at least one other device,
• wherein the priority is determined based on accessibility according to a voice command, and
• wherein the amount of physical activity is counted by a device having the highest priority determined based on the priority of the electronic device and the at least one other device using weighted value, upon receiving the voice command by at least one of the electronic device and the at least one other device.
