Motion controller

A motion controller controls the motion of some object. Frequently motion controllers are implemented using digital computers, but motion controllers can also be implemented with only analog components as well.

Motion controllers require a load (something to be moved), a (something to cause the load to move), some sensors (to be able to sense the motion and monitor the prime mover), and a controller to provie, packaging, distribution or use.

Motion controllers are used to achieve some desired benefit(s) which can include:

The history of true video motion control without a joystick goes back to 1987 where an experimental photographer Vincenzo Giovanni Ruello has released archive footage showing him moving his hand in front of a specially designed video graphic and causing the centre of the graphic to move and change without disturbance to the outer graphic a system later perfected in the 21st century with such systems as Wii and others.

Motion controllers using accelerometers are used as controllers for video games, which was publicly introduced in 1981 by Datasoft's "Le Stick" controller for the Atari 2600, and made more popular since 2006 by the Wii Remote controller for Nintendo's Wii console, which uses accelerometers to detect its approximate orientation and acceleration, and serves an image sensor, so it can be used as a pointing device. It was followed by other similar devices, including the ASUS Eee Stick, Sony PlayStation Move (which also uses magnetometers to track the Earth's magnetic field and computer vision via the PlayStation Eye to aid in position tracking), and HP Swing. Other systems use different mechanisms for input, such as Microsoft's Kinect, which combines infrared structured light and computer vision, and the Razer Hydra, which uses a magnetic field to determine position and orientation.
