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:
A system and a method for motion estimation are disclosed. The system for motion estimation in accordance with an embodiment of the present invention includes: a plurality of motion sensors mounted near joints of a body and configured to provide motion information; a depth sensor configured to provide 3-dimensional image information having a 3-dimensional coordinate for each pixel; and a motion estimation device configured to estimate a motion by use of the motion information and the 3-dimensional image information, wherein the motion estimation device includes: a converging unit configured to compute mounting position information of the motion sensors by performing an initialization process by converging the motion information and the 3-dimensional image information; and an estimating unit configured to estimate the motion by computing a state vector including the mounting position information and the motion information.

Abstract:
A fitness device-based simulator and a simulation method using the simulator. The fitness device-based simulator includes a feature point extraction unit for acquiring action-sensing information of a user who is located on a fitness device, and extracting feature points for a body skeletal structure of the user based on the action-sensing information, a feature point cluster generation unit for generating multiple feature point clusters by clustering two or more of the feature points, and setting respective cluster symbols for multiple feature point clusters, an exercise pattern information accumulation unit for generating and storing information about a state transition between the multiple feature point clusters of the user, and an exercise state prediction unit for predicting a subsequent exercise state of the user by predicting a feature point cluster subsequent to a feature point cluster currently being generated for the user, based on state transition information.
Abstract:
An apparatus and method for providing an image-based indoor map. The apparatus for providing an image-based indoor map includes an indoor map request reception unit for receiving an indoor map request for a building having multiple floors from a terminal of a user, an indoor map acquisition unit for acquiring an indoor map corresponding to the building in response to the indoor map request from an indoor map database (DB), and an indoor map provision unit for providing the terminal of the user with information about at least one of multiple image indoor maps, in which multiple floors and Levels of Detail (LoDs) of each image are taken into consideration, and Points of Interest (POIs) for respective multiple floors, based on the indoor map.
