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.

Abstract: Disclosed herein is an apparatus and method for correcting the location of a base station. The apparatus includes a data collection unit for receiving collected data including collection places and scan data acquired from the collection places from a collection-only terminal, and receiving scan data having no collection places from a user service terminal. A determination unit obtains correlations between respective base stations based on a number of times each base station in an identical search group is found in a search using the collected data or the scan data, and determines whether a base station has been moved, deleted or added, based on the correlations between respective base stations. A location specification unit specifies a location of the corresponding base station that has changed due to any one of the movement, deletion, and addition of the base station, based on results of the determination.
