In computing, a keyboard controller is a device that interfaces a keyboard to a computer. Its main function is to inform the computer when a key is pressed or released. When data from the keyboard arrives, the controller raises an interrupt (a keyboard interrupt ) to allow the CPU to handle the input.
A pointing stick (or trackpoint, also referred to generically as a nub or nipple) is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice , touchpads or trackballs , operating system software translates manipulation of the device into movements of the pointer ...
Computer systems such as laptops often produce large amounts of heat which must be dissipated. This is typically done by activating a fan to blow air over the components that are producing heat; the fan is not simply turned on or off, but is driven at high speed by the embedded controller for a short time and then left running at low speed ...

The computer keyboard is modelled after the typewriter keyboard and was designed for the input of written text. A mouse is a handheld pointing device used in addition to the keyboard. For games, the keyboard typically controls movement of the character while the mouse is used to control the game camera or used for aiming.
User-made game port to USB adapter supporting FFB on the Sidewinder Force Feedback Pro only. Simple joystick support on 3D Pro, Precision Pro, Precision Pro Plus, and Wheel. [12] As the PC joystick port is input-only, the only way for data to be sent to the joystick (to trigger force feedback events) is to use the MIDI capabilities of the port ...
Possible elements of a video game joystick: 1. stick, 2. base, 3. trigger, 4. extra buttons, 5. autofire switch, 6. throttle, 7. hat switch (POV hat), 8. suction cups. A joystick, sometimes called a flight stick, 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.
The game port is a device port that was found on IBM PC compatible and other computer systems throughout the 1980s and 1990s. It was the traditional connector for joystick input, and occasionally MIDI devices, until made obsolete by USB in the late 1990s.
