A video game or 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 visual feedback. This feedback is shown on a video display device, such as a TV set, monitor, touchscreen, or virtual reality headset. Video games are often augmented with audio feedback delivered through speakers or headphones, and sometimes with other types of feedback, including haptic technology.
Video games are defined based on their platform, which include arcade video games, console games, and personal computer games. More recently, the industry has expanded onto mobile gaming through smartphones and tablet computers, virtual and augmented reality systems, and remote cloud gaming. Video games are classified into a wide range of genres based on their type of gameplay and purpose.
The first video game prototypes in the 1950s and 1960s are simple extensions of electronic games using video-like output from large room-size computers. The first consumer video game is the arcade video game Computer Space in 1971.
