1. A system comprising:
- an irradiation light transmitting apparatus comprising at least one light irradiator to irradiate irradiation light;
a light receiving apparatus comprising at least one light receiver to receive the irradiation light;
a remote apparatus comprising one of the irradiation light transmitting apparatus or the light receiving apparatus; and
an estimation apparatus to measure an attribute of the irradiation light received by each of the at least one light receiver, and to estimate at least one of a position and a direction of the remote apparatus based on the measured attribute.

Abstract
A system and method for estimating a position and a direction using an infrared light are provided. The system may measure an intensity of an irradiation light irradiated by each light irradiator through each light receiver, and may estimate a position and a direction of a remote apparatus, based on the measured intensity, a light receiving directivity, and a light emitting directivity.
