A video game is an electronic game that involves interaction with a user interface to generate visual feedback on a video device. The word video in video game traditionally referred to a raster display device. However, with the popular use of the term "video game", it now implies any type of display device. The electronic systems used to play video games are known as platforms; examples of these are personal computers and video game consoles. These platforms range from large computers to small handheld devices. Specialized video games such as arcade games, while previously common, have gradually declined in use.

The input device used to manipulate video games is called a game controller, and varies across platforms. For example, a dedicated console controller might consist of only a button and a joystick. Another may feature a dozen buttons and one or more joysticks. Early personal computer games often needed a keyboard for gameplay, or more commonly, required the user to buy a separate joystick with at least one button.Fact: date=November 2008 Many modern computer games allow, or even require, the player to use a keyboard and mouse simultaneously.

Video games typically also use other ways of providing interaction and information to the player. Audio is almost universal, using sound reproduction devices, such as speakers and headphones. But other feedback may come via haptic peripherals, such as vibration force feedback.

History

main: History of video games

Early games used interactive electronic devices with various display formats. The earliest example is from 1947—a "Cathode Ray Tube Amusement Device" was filed for a patent on January 25, 1947 by Thomas T. Goldsmith Jr. and Estle Ray Mann, and issued on December 14, 1948 as U.S. Patent 2455992.

Inspired by radar displays, it consisted of an analog device that allowed a user to control a vector-drawn dot on the screen to simulate a missile being fired at targets, which were drawings fixed to the screen.

Other early examples include:

• The NIMROD computer at the 1951 Festival of Britain
• OXO a tic-tac-toe Computer game by Alexander S. Douglas for the EDSAC in 1952
• Tennis for Two, an interactive game engineered by William Higinbotham in 1958
• Spacewar!, written by MIT students Martin Graetz, Steve Russell, and Wayne Wiitanen's on a DEC PDP-1 computer in 1961.

Each game used different means of display: NIMROD used a panel of lights to play the game of Nim, OXO used a graphical display to play tic-tac-toe Tennis for Two used an oscilloscope to display a side view of a tennis court, and Spacewar! used the DEC PDP-1's vector display to have two spaceships battle each other.
