PROBLEM TO BE SOLVED: To provide an area estimation apparatus, an area estimation method, and a program, which are suited for easily estimating the ranges of position and direction that a controller can assume.;SOLUTION: A sensor bar has at least two non-directional light emitting units 201 at predetermined intervals to each other that emit infrared rays non-directionally, and at least one directional light emitting unit 204 that emits infrared rays with directivity is provided in a position a predetermined distance away from the outside of each of the two non-directional light emitting units. A controller 202 has a sensor for detecting infrared rays, and a position where the controller 202 is disposed relative to the sensor bar is estimated based on the light source of the infrared ray detected and the position of the infrared ray detected.;COPYRIGHT: (C)2011,JPO&INPIT
