To limit the scope of the project, 3 of the most interesting possible options have been chosen.
I am ranking them in complexity like this (low to high):
- "Rocket" ... to make the underlaying interaction only 4 leds and 4 buttons are required.
- "Levels" ... requires 4 sliders which are more expensive but easy to implement. Feedback whether being right or wrong could come in the form of an LED or sound.
- "Card Swipe" ... requires a more delicate hardware-build with sensors to catch a (credit-)card swipe and is one of the most infamous tasks of the game.
To make the interactions more appealing, I believe a buzzer/speaker for chimes should make it much more enjoyable. This would be added to all mini-games.
Sound feedback can be related directly to the interaction or indicate error and success.
