Wii U GamePad
The Wii U GamePad is the standard controller used by the Nintendo Wii U video game console. Incorporating traits from tablet computers, the GamePad has traditional input methods (such as buttons, dual analog sticks, and a D-pad), touchscreen controls, and motion controls. The touchscreen can be used to supplement a game by providing alternate, second screen functionality or an asymmetric view of a scenario in a game. The screen can also be used to play a game strictly on the GamePad screen, without the use of a television display. Conversely, non-gaming functions can be assigned to it as well, such as using it as a television remote.
The Wii U GamePad can be used in conjunction with other controllers compatible with the console, such as the Wii Remote Plus, Wii Balance Board, and the more conventional Wii U Pro Controller.
History
Nintendo's development team had determined that the Wii's notification light did not provide enough information to be useful beyond whether it had received content or not. With the complexity of modern televisions, designer Shigeru Miyamoto believed that a monitor separate from the console would provide an easier way to check on the console's status without needing to use the television. Its operation as a supplemental display was also inspired by the common use of a similar display at karaoke establishments in Japan, which displays song information and also allows its users to select their next song.
