Abstract

An exercise analysis apparatus includes a feature point detection unit that detects a feature point in a user'"'"'s running by using a detection result from an inertial sensor, and an exercise information generation unit that analyzes the user'"'"'s running with a timing at which the feature point detection unit detects the feature point as a reference by using the detection result from the inertial sensor, so as to generate exercise information of the user.

Claims
