<p>PROBLEM TO BE SOLVED: To make exchanging positional information efficient optimizing the positional information to be exchanged by taking particularity of short-range wireless communication into consideration.SOLUTION: Positional information (latitude information and longitude information) having a prescribed digit number from a first digit to a second digit of position detection results (latitude and longitude) in each device (100, 200-200, 300) is exchanged among the devices (100, 200-200, 300) that perform short-range wireless communication according to a prescribed standard. On receiving positional information on the other devices (200-200, 300) by such operation of exchanging the positional information, an information processing unit 130 identifies positions of the other devices that have transmitted the received positional information on the basis of the received latitude information and longitude information and a position detection result by a position detecting unit 120.</p> |
