A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. A joystick, also known as the control column, is the principal control device in the cockpit of many civilian and military aircraft, either as a center stick or side-stick. It often has supplementary switches to control various aspects of the aircraft's flight. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick. Joysticks are also used for controlling machines such as cranes, trucks, underwater unmanned vehicles, wheelchairs, surveillance cameras, and zero turning radius lawn mowers. Miniature finger-operated joysticks have been adopted as input devices for smaller electronic equipment such as mobile phones. == Aviation == Joysticks originated as controls for aircraft ailerons and elevators, and is first known to have been used as such on Louis Bleriot's Bleriot VIII aircraft of 1908, in combination with a foot-operated rudder bar for the yaw control surface on the tail. The name "joystick" is thought to originate with early 20th century French pilot Robert Esnault-Pelterie. There are also competing claims on behalf of fellow pilots Robert Loraine, James Henry Joyce, and A. E. George. Loraine is cited by the ''Oxford English Dictionary'' for using the term "joystick" in his diary in 1909 when he went to Pau to learn to fly at Bleriot's school. George was a pioneer aviator who with his colleague Jobling built and flew a biplane at Newcastle in England in 1910. He is alleged to have invented the "George Stick" which became more popularly known as the joystick. The George and Jobling aircraft control column is in the collection of the Discovery Museum in Newcastle upon Tyne, England. Joysticks were present in early planes, though their mechanical origins are uncertain. The coining of the term "joystick" may actually be credited to Loraine, as his is the earliest known usage of the term, although he most certainly did not invent the device. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「joystick」の詳細全文を読む スポンサード リンク
