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.
