Abstract

First through third light reception elements 111–113 receive infrared data D from an operation input transmission section 2, and output the received data to an operation input permission determination section 12a. The operation input permission determination section 12a distinguishes among the first through third infrared light reception elements 111–113, thereby determining in which space an operation input has been performed, and analyzes the description of the operation input, thereby determining whether to accept the operation input. A calculation processing section 13a performs various processes based on the description of the operation input from the operation input permission determination section 12a, a processing result of a position detection section 17, and map data stored in a map data storage section 16. A drawing processing section 14a performs a process of outputting a processing result of the calculation processing section 13a to first and second displays 3 and 4.
