Communication system, communication method, and communication device
First Claim
1. A communication system comprising a first communication device and a second communication device that communicate with each other,the first communication device comprising:
- a physical quantity detection unit configured to detect a physical quantity that changes as the first communication device moves;
a direction determination unit configured to determine a communication direction between the first and second communication devices in accordance with a change in the physical quantity detected by the physical quantity detection unit; and
a communication unit configured to communicate with the second communication device based on the communication direction that is determined by the direction determination unit.

Abstract
A disclosed communication system, communication method, and communication device enable an intended command to be easily acquired from a movement of an operator and executed. The communication system includes a first communication device and a second communication device communicating with each other. The first communication device includes a physical quantity detection unit that detects a physical quantity that changes as the first communication device moves. Based on an increase or a decrease in the physical quantity detected by the physical quantity detection unit, a communication direction is determined by a direction determination unit of the first communication device. Based on the thus determined communication direction, a communication unit of the first communication device communicates with the second communication device.
