Stride-based route guiding apparatus and method
First Claim
1. A stride-based route guiding apparatus, comprising:
- a route information providing unit for calculating a traveling distance to a specific position in terms of a number of steps, and a control unit for performing a route guidance using the number of steps output from the route information providing unit during the route guidance, wherein the route information providing unit, comprises;
a sensor for sensing a stride of a pedestrian;
a stride detecting unit for detecting the stride by extracting a feature repeated at the stride of the pedestrian from an output pattern of the sensor, and a pace setting unit for estimating a pace of the pedestrian using a stride frequency according to a size of variance of the sensor value and a result of stride detection.

Abstract
Disclosed is a stride-based route guiding apparatus and method capable of providing a pedestrian with a stride-based route. The method includes detecting a stride of the pedestrian on the basis of a pace inherent to the pedestrian of interest and converting a remaining distance from a current position to a major position or destination into the number of steps so as to provide the pedestrian with the number of steps to the major position or destination when a route is shown, using a navigation system built in a mobile terminal. Since the route is shown on the basis of the number of steps inherent to the pedestrian, the pedestrian can receive the routing more familiar to herself or himself, and easily and intuitively perceive the route from the current position to the major position or destination.
