Evaluation of effectiveness of position / orientation measurement method for indoor AR display guidance

Many services on user’s location information are developed by using GPS (Global Positioning System). However, the GPS’s positioning accuracy drops significantly indoors. We have proposed and developed an indoor positioning method without GPS. We have already proposed a method to estimate the position and direction indoor by using short-range wireless communication and electronic compass based on directivity antennas without indoor map data.In this paper, in order to evaluate our method, we measure directional characteristics of the directivity antennas of the transmitter and receiver.
