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.
A touchscreen is an input device that allows the user to interact with the computer by touching the display screen. The first attempt at a handheld game console with touchscreen controls was Sega's intended successor to the Game Gear , though the device was ultimately shelved and never released due to the high cost of touchscreen technology in ...
The first detection method, used by the NES Zapper, involves drawing each target sequentially in white light after the screen blacks out. The computer knows that if the diode detects light as it is drawing a square (or after the screen refreshes), then that is the target at which the gun is pointed.
A pointing stick on a mid-1990s-era Toshiba laptop. The two buttons below the keyboard act as a computer mouse: the top button is used for left-clicking while the bottom button is used for right-clicking. Optical pointing sticks are also used on some Ultrabook tablet hybrids, such as the Sony Duo 11, ThinkPad Tablet and Samsung Ativ Q.
When IBM finally did release a joystick, for the IBM PCjr, it was a version of the Kraft stick. However, it connected to the computer using two incompatible 7-pin connectors, which were mechanically connected together as part of a larger multi-pin connector on the back of the machine. [11] This eliminated the need for the Y-adapter. [12]
The GamePad Pro utilized the 'button' signal lines on an analog PC joystick port to send digital signals (referred to as "GrIP") [1] to allow for both the use of ten buttons and the simultaneous use of up to four controllers connected by the controller's built-in piggyback plug. A switch on the pack of the non-USB pad could be used to allow the ...
A light pen detects changes in brightness of nearby screen pixels when scanned by cathode-ray tube electron beam and communicates the timing of this event to the computer. Since a CRT scans the entire screen one pixel at a time, the computer can keep track of the expected time of scanning various locations on screen by the beam and infer the ...
A light pen is a device similar to a touch screen, but uses a special light-sensitive pen instead of the finger, which allows for more accurate screen input. As the tip of the light pen makes contact with the screen, it sends a signal back to the computer containing the coordinates of the pixels at that point. It can be used to draw on the ...
