MAGNETIC-FIELD-MAP-BASED STRIDE ESTIMATING DEVICE AND A METHOD USING THE SAME, CAPABLE OF REDUCING THE MOVED DISTANCE OF A USER NECESSARY FOR ESTIMATING A STRIDE OF THE USER

摘要

PURPOSE: A magnetic-field-map-based stride estimating device and a method using the same are provided to estimate the moved distance of a user based on a magnetic field map, thereby reducing errors of estimating a location.;CONSTITUTION: A magnetic-field-map-based stride estimating device (100) includes a memory (110), a magnetic sensor (120), an acceleration sensor (130), and a processor (140). A magnetic field map is stored in the memory. The magnetic sensor measures a magnetic field at a position of the stride estimating device. The acceleration sensor measures the acceleration of the stride estimating device. The processor estimates a stride of a user based on the magnetic field map, the measured magnetic field, and the measured acceleration.;COPYRIGHT KIPO 2013;[Reference numerals] (111) Magnetic field map; (120) Magnetic fileld sensor; (121) Magnetic field figure; (130) Acceleration sensor; (131) Acceleration figure; (140) Processor; (141) Moving distance measuring unit; (142) Step detection unit; (143) Stride estimating unit; (AA) Memory
