Abstract
An acceleration information detecting unit of an acceleration detecting apparatus having an acceleration sensor with at least one axis that measures acceleration in a back and forth direction (or a right and left direction) of a walking person. Acceleration data indicating the acceleration is sent to a wireless communication control unit. The wireless communication control unit sends the acceleration data to a physical movement analyzer using a short-distance wireless communication method. On the other hand, the wireless communication control unit of the physical movement analyzer receives the acceleration data that is sent from the acceleration detecting apparatus using a short-distance wireless communication method and sends it to a walking speed detecting unit. The walking speed detecting unit estimates strides and walking period based on the received acceleration data and calculates the walking speed based on the strides and the walking period.
