Patent attributes
A device includes a processor; and a memory connected to the processor and storing an artificial intelligence algorithm, first to third location data, wherein the memory stores program instructions which, when executed by the processor, cause the processor to, two-dimensionally map the first location data to a first point according to a preset mapping method, two-dimensionally map the second location data to a second point according to the mapping method, two-dimensionally map the third location data to a third point according to the mapping method, set a reference point, a first reference line, and a second reference line according to a preset method through the first point to the third point, generate movement information about a location where a user has moved from a location corresponding to the reference point by using location information received from a user terminal, and train the artificial intelligence algorithm using the movement information.
