Project: Game Controller | Microphone Controller for Friday Night Funkin'

 

For this project I made a controller for the game Friday Night Funkin'. It's a rhythm game, similar to DDR where you press the corresponding key when it reaches the top bar. Normally this would be done by pressing the W, A, S, and D or Arrow Keys but for this controller you just tilt the microphone in the direction of the arrow on screen. I chose a microphone for the housing of my controller as the game is very much about music and even uses a microphone similar to this one for some of it's logos. As far as gameplay goes, it's fairly straight forward. The player simply tilts the microphone in the correct direction at the correct time. The player must return to "zero" or back to a vertical position before making another input. The significance of this controller's appearance pertains to the relationship between rhythm/music and microphones/movement. The controller takes input through the accelerometer in the CPE and maps that motion in the X and Y directions to a threshold that is constantly checked. If the threshold is reached in a certain direction, it's respective input is triggered.

Question: One of the things I wanted to add was to use the on board microphone of the CPE as an input, but I couldn't come up with any logical use for this. What could I have used the microphone for?
