I have no idea what I want to do for this. Part of me wants to build a video game with a custom controller like a glove or something and Google Glass to have an augmented reality game, but that's less PComp and more programming unless I really customize the gloves. Pressure sensors could be used for item triggers but I'm struggling to think of other interactive ideas
Something else would maybe be a functional pet robot. It reacts positively when you pet it, chases after unsuspecting ITPers, while avoiding walls, and has LEDs to reflect mood. It needs more interactive elements, but I'm not sure if voice commands and/or gestures would work? I'm not sure
I really hope other people have better ideas.
