Abstract: Provided are a method of recognizing an emotion of a driver and an apparatus using the same. The method includes receiving emotion recognition information including at least one of vehicle state information and driver emotion state information, determining whether a dominant emotion state exists among one or more emotion states possessed by the driver on the basis of the emotion recognition information and an emotion recognition model, and performing a reaction inducing interaction with respect to the driver determined on the basis of the determined dominant emotion state together with the driver when the dominant emotion state of the driver is determined to exist.

Abstract: A computing device loads signal strengths of wireless communication signals collected at a plurality of first collection areas and position information of the first collection areas, sets positions of a plurality of virtual transmitting apparatuses. The computing device estimates signal strengths of wireless communication signals in a plurality of second collection areas based on a distance between a position of each of the virtual transmitting apparatuses and each of the first collection areas, a signal strength collected at each of the first collection areas, and a distance between a position of each of the virtual transmitting apparatuses and each of the second collection areas. The computing device determines an optimal virtual transmitting apparatus among the virtual transmitting apparatuses, and generates positioning data at the second collection areas based on signal strengths in the second collection areas which are estimated based on a position of the optimal virtual transmitting apparatus.
