Patent ID: 7811203

Claim:
A walking behavior detection apparatus for a walker comprising: first detecting means for detecting a horizontal walking behavior of a walker regarding a level; altitude variation detecting means for detecting altitude variation of the walker; estimating means for estimating a walking behavior of the walker on the basis of a combination of the horizontal walking behavior and the detected altitude variation, wherein said walking behavior comprises a plurality of distinct categories based on said combination; a database for storing geographical information corresponding to the detected behavior of the walker; a second detecting means for detecting a position and a traveling direction of the walker; change point detecting means for detecting a behavior change point of the walking behavior of the walker on the basis of the estimated walking behavior of the walker and a geographical change point being that geographical information stored in the database which corresponds to the estimated behavior of the walker; and compensating means for compensating the detected position of the walker and the detected traveling direction on the basis of the behavior change point and the geographical change point.
