Abstract: Provided are a method and apparatus for estimating a position of a pedestrian in a virtual reality. A method of estimating a position of a pedestrian walking on a locomotion interface device includes detecting a stance phase based on first sensed data; receiving driving speed information of the locomotion interface device from the locomotion interface device; and estimating a step length of the pedestrian based on second sensed data, in which the step length is estimated in consideration of a driving speed of the locomotion interface device in the stance phase. It is possible to estimate a distance actually traveled by a pedestrian and a position of the pedestrian in a virtual reality.
