Title:
DETECTOR FOR MOTION OF PEDESTRIAN
Document Type and Number:
Japanese Patent JP2007093433
Kind Code:
A
Abstract:

To solve the following problems: there are no devices capable of correctly recognizing walking motion accompanying vertical motion; moreover though in the walking motion accompanying vertical motion, walking is performed with a stride different from that in walking on a level, there are no devices for detecting that.

A sensor for detecting a change in height and a device for detecting walking motion on a level are combined, to detect walking motion taking its vertical movement into consideration. By the use of this device, recognition of walking motion accompanying vertical movement becomes possible. Moreover, accurate stride detection becomes possible, and higher-accuracy position detection becomes possible. Moreover, where on the geography a pedestrian is can be estimated by comparing the walking motion with geographical information.
