First Claim
1. 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.

Abstract
A behavior of a walker is detected according to combination of detection of the walking behavior on a level and an altitude variation of the walker to more accurately detect the behavior of the walker. A burned calorie can be obtained according to the type of the walking behavior. An altitude variation can be obtained more accurately by integrating altitude variation only at sections with vertical movement during walking. A stride is estimated according to the behavior of the walker in consideration of the vertical movement. Obtained position and traveling direction are used for compensating values in inertial navigation system. The behavior with and without vertical movement is used in a walker navigator and a worker observing system including a worker terminal carried by the walker for detecting the behavior of the worker and a worker observing terminal for providing the detected position and behavior of the walker.
