<p>PROBLEM TO BE SOLVED: To analyze walking characteristics comprehensively grasped by various walking parameters which influence a gait, by using an acceleration sensor portable in a daily life.SOLUTION: A method for analyzing walking characteristics includes: measuring an acceleration speed in walking with an acceleration sensor for a plurality of subjects; extracting a plurality of acceleration speed principal components by time division and principal component analysis of measured acceleration speed data; and calculating the principal component scores thereof. Furthermore, the method includes: extracting a plurality of walking principal components for a plurality of pedestrians by walking parameter principal component analysis including walking factors measured by walking marks; calculating the principal component scores as walking characteristic scores; and acquiring a relational expression between the principal component scores of the plurality of acceleration speed principal components, and the walking characteristic scores. On the other hand, the method includes: calculating the acceleration speed principal component scores from the acceleration speed data in walking of an arbitrary subject; and calculating the walking characteristic scores from the principal component scores, using the relational expression.</p> |
