Video game peripheral

A video game accessory is a distinct piece of hardware that is required to use a video game console, or one that enriches the video game's play experience. Essentially, video game accessories are everything except the console itself, such as controllers, memory, power adapters (AC), and audio/visual cables. Most video game consoles come with the accessories required to play games out of the box (minus software): one A/V cable, one AC cable, and a controller. Memory is usually the most required accessory outside of these, as game data cannot be saved to compact discs. The companies that manufacture video game consoles also make these accessories for replacement purposes (AC cords and A/V cables) as well as improving the overall experience (extra controllers for more players, or unique devices like light guns and dance pads). There is an entire industry of companies that create accessories for consoles as well, called third-party companies. The prices are often lower than those made by the maker of the console (first-party). This is usually achieved by avoiding licensing or using cheaper materials. For the mobile systems like the PlayStation Portable and Game Boy iterations, there are many accessories to make them more usable in mobile environments, such as mobile chargers, lighting to improve visibility, and cases to both protect and help organize the collection of system peripherals to. Newer accessories include many home-made things like mod chips to bypass manufacturing protection or homemade software.

The most common accessory for video game consoles are the controllers used to play the games. The controllers have evolved since the day of Pong and the spinner. Now there are direction controls as well as many types of other inputs.

One type of directional control is the directional pad or D-Pad. The D-Pad is designed to look like an addition sign with each branch being one of the four cardinal directions; left, right, up, and down. It has been around since the original Nintendo Entertainment System, and has been in every Nintendo system since. Another feature in the recent console controllers are the analog sticks, used for 360ْ directional control. Often used for camera angle control, the idea is to give the player full control by allowing any direction to be used. The analog controls made their first appearance in the 1970s consoles under the name joystick; they made a reappearance in console systems with the Nintendo 64. Analog sticks have been used in every modern console since. There is no analog stick on the Wii Remote, but it is present on the Nunchuk attachment bundled with the Wii console. The most recent development in directional controls is free motion control. Using accelerometers in the Wii Remote and Nunchuk, acceleration in any direction can be detected and measured. This is still a new type of control scheme and is fully taken advantage of in the Wii as well as the PlayStation 3's SIXAXIS controller, and PlayStation MOVE controller that has tilt detection.
