Game Controller: Osu!taiko (Gianni Rodriguez)

 

The controller I made for Osu!taiko was a drum shape device that mapped input in the game according to the direction the controller is tilted in. The conceptual model was meant to have the logos of the taiko characters on the top of the drum to make it relate to the game itself. After spending time working on the frame for the controller, I had to scrap that idea due to how I made the framing. Covering the controller in something was honestly the hardest part out of the whole project, it was a struggle to find something that would cover it and also stay on the controller as the user is tilting it. Ended up going with a thick string that I had in my house, it is not the greatest looking thing but it got the job done and that was what I was worried about. The way the input works on the controller is the accelerometer registers input through numbers, and if the controller is tilted far enough in one direction, it registers that as input. The output is a press of a certain key on the keyboard, and each direction results in a different key being pressed. This allows us to play Osu!taiko because there are only four inputs in the game and only the keyboard is being used. The drum shape of the controller is due to the nature of the game itself, the player is meant to be hitting a drum in accordance with the notes that are appearing on the screen.

 The hardest part for me by far was the physical design of the controller. If you were to make edits to the design how would you go about it and what would you do differently?
