Video Games
A video game is an electronic game in which one or more people interact, through a controller, with a device that displays video images.1 This electronic device, generically known as a "platform," can be a computer, a machine arcade, a game console or a portable device, such as a mobile phone. Video games are, year by year, one of the main industries of art and entertainment.
The input device, used to manipulate a video game is known as a video game controller, or controller, and varies depending on the platform. For example, a controller could only consist of a button and a joystick, while another could have a dozen buttons and one or more levers (command). The first computer games used to use a keyboard to carry out the interaction, or they required the user to acquire a joystick with at least one button.2 Many modern computer games allow or require the user to use a keyboard and a mouse simultaneously. Among the most typical controllers are gamepads, joysticks, keyboards, mice and touch screens.
Generally, video games make use of other ways, apart from the image, to provide interactivity and information to the player. The audio is almost universal, using sound reproduction devices, such as speakers and headphones. Another type of feedback is done through haptic peripherals that produce vibration or force feedback, sometimes using vibration to simulate force feedback.
