In
the game Guitar Hero, players play the game as if they were a guitar player.
The game displays notes on screen for a certain type of rock song. The players
then use a game controller to press certain buttons that corresponds to the
notes on the screen, which will then play the song. To make it even more
realistic to playing an electric guitar, the company has created a controller
that is like a small electric guitar shown in Figure 1. Fret buttons on this
controller are like holding the notes on an electric guitar and another strum
button is used to simulate the player strumming the guitar. Even with this game
controller, users want more from the game. They want to be able to play their
own electric guitar. So far in the game industry there isn't a device that will
use a real electric guitar to play the game. Having sold over 10 million copies
of the three Guitar Hero games, this device will have a large market.
