Friday Night Funkin Game Controller

The original design for my game controller was made with the intention of using four separate PIR motion sensors in conjunction with the Circuit Playground Express. However, during the construction of the controller, I realized there were hardware inconsistencies and thus that idea was shelved. This final design uses only two of the PIR motion sensors in addition to a potentiometer. The conceptual model was designed to resemble the arrows of Friday Night Funkin. I used a thermoplastic called Worbla in order to create a sturdy shape for the arrows. These were created before discovering the hardware issues but I decided to use three of the arrows in the end. The signifiers of this design were the arrows allowing the user to easily identify which direction the sensor would correspond to. The feedback is that the user can see the corresponding arrows pressed on-screen while the relevant motion is applied to the sensors and potentiometer. The input and output mapping are as follows: The potentiometer, when turned counterclockwise, will output a left arrow or the “A” key. When turned clockwise the output will be the right arrow or the “D” key. The two motion sensors will output the up and down arrows or the “W” and “S” keys respectively. The affordances are the four input mechanics the user has access to. All other components are hidden.

Do you think this design is too confusing given the use of containers meant for the previously intended hardware?
