Wii Sports --- The motion control technology

I believe most of us all have played or heard of the game " Wii Sports". The game is a collection of five sports simulation, which best shows the idea of one new technology at that time.Several years ago this game surprised so many people by its unexpected idea, and in my mind it is one of the most interesting ideas that ever used in gaming----The motion control technology.

Motion control is a sub-field of automation, encompassing the systems or sub-systems involved in moving parts of machines in a controlled manner. It is a technology which largely used in computer science and engineering. The main components involved typically include a motion controller, an energy amplifier, and one or more prime movers or actuators. Motion control may be open loop or closed loop. In open loop systems, the controller sends a command through the amplifier to the prime mover or actuator, and does not know if the desired motion was actually achieved. Typical systems include stepper motor or fan control. For tighter control with more precision, a measuring device may be added to the system (usually near the end motion). When the measurement is converted to a signal that is sent back to the controller, and the controller compensates for any error, it becomes a Closed loop System.

Motion control is widely used in the packaging, printing, textile, semiconductor production, and assembly industries. Motion Control encompasses every technology related to the movement of objects. It covers every motion system from micro-sized systems such as silicon-type micro induction actuators to micro-siml systems such as a space platform. But, these days, the focus of motion control is the special control technology of motion systems with electric actuators such as dc/ac servo motors. Control of robotic manipulators is also included in the field of motion control because most of robotic manipulators are driven by electrical servo motors and the key objective is the control of motion.

The motion control technology brings people "into" backgrounds and pictures. It leads a new period in computing realm, and the game "Wii Sports" is one of the best representations of motion control.
