A video game, also known as a computer game, is an electronic game that involves interaction with a user interface or input device such as a joystick, controller, keyboard, or motion sensing device to generate audiovisual feedback. This feedback is most commonly shown on a video display device, such as a TV set, monitor, touchscreen, or virtual reality headset. Some computer games do not always depend on a graphics display; for example, text adventure games and computer chess can be played through teletype printers. Video games are often augmented with audio feedback delivered through speakers or headphones, and sometimes with other types of feedback, including haptic technology.
