<P>PROBLEM TO BE SOLVED: To achieve a novel perception system. <P>SOLUTION: The perception system comprises an exciter 1 attached to a person or an object, an electromagnetic field variation detector 2 provided at a distance from the exciter 1, and a perception device 3. The electromagnetic field variation detector 2 has two antennas 20A, B provided with a space between one another. Electromagnetic waves from the exciter 1 are received by the antennas 20A, B, and the phase difference of two electric signals thus received is measured. The perception device 3 replaces the time variation of a phase difference, measured by the electromagnetic field variation detector 2, by a phenomenon appealing to perception of a person thus making the time variation of a phase difference perceptible for a person. <P>COPYRIGHT: (C)2013,JPO&INPIT |
