Game Controller: Five Night's at Freddy's

Vision & Disclaimer 

For the final project I decided to create a game controller for Five Nights at Freddy's. Taking into consideration the gameplay and theming I decided to turn the laptop the player uses in-game into the controller in an attempt to better immerse the player in the gameplay. One of the biggest challenges I faced was realizing that FnAF isn't actually played using any hotkeys or keyboard controls and is only controlled using the mouse. Given that, I must state as a disclaimer, that I found external code that takes keyboard commands and converts it into mouse movements on the screen, thus emulating how FnAF could be played with only the keyboard.

Controller Description

 With that sorted, here's the description for the actual controller. The "laptop" would sit on the player's lap or on the desk in front of them and then be controlled using the various sensors. When the "laptop" is opened, the laptop in game is opened to view the cameras, and then using the potentiometer and the position switch the player can cycle through each of the cameras; closing the laptop of course closes it in game as well. The position switch is used to control the doors while the "laptop" is closed, and the potentiometer and photoresistor work in tandem to turn the lights on and off depending on brightness and position of the potentiometer.

Peer Question

Although the player would be looking at the actual computer screen most times do you think more visual aids on the controller itself would be useful?
