MOVEMENT INSTRUCTION DEVICE, COMPUTER PROGRAM, MOVEMENT INSTRUCTION METHOD, AND MOBILE BODY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a movement instruction device or the like capable of intuitively instructing a rotational movement to a mobile body.SOLUTION: The movement instruction device includes a first receiving unit for receiving input of a first coordinate from a coordinate input device; a first determination unit for periodically determining presence or absence of change in the first coordinate; a second receiving unit for receiving input of a second coordinate from the coordinate input device; a second determination unit for periodically determining presence or absence of change in the second coordinate; a stop position receiving unit for receiving a stop position coordinate of the second coordinate from the coordinate input device when the first determination unit determines that there is no change in the first coordinate, the second determination unit determines that there is change in the second coordinate, and then the second determination unit determines that there is no change in the second coordinate; and a calculation unit for calculating an angle formed by a line segment between initial coordinates of the first coordinate and the second coordinate, and a line segment between the first coordinate and the stop position coordinate. The instruction unit instructs a rotation movement to the mobile body according to the calculated angle.
