Disclosed are an apparatus and a method for fast path search using learning of a heuristic function according to the present invention. An apparatus for fast path search according to the present invention includes: an input unit to receive destination information from a user, and to receive a search request for a path to the received destination information; a location recognizing unit to obtain current location information of the user when the search request for the path is received; and a control unit to search a map for a path from a start node corresponding to the current location information to a destination node corresponding to the destination information using a heuristic evaluation function.

Apparatus for fast path search by learning heuristic function and method thereof

Disclosed are a device and a method for localizing a user indoors using a wireless local area network, and more particularly, a localization device and a localization method that improve localization accuracy by fusing various context information when localizing a user-portable/wearable device connected with a wireless network based on an RF-based wireless network such as ZigBee.
