In a crowded parking lot, the only thing that determines how long we would find a parking spot is LUCK! We just wander from one aisle to another, and go back to see if any car has just left. Maybe we can design some application in the cell phone that would navigate people to the available parking spots, with real-time information update?
What if you have an important phone call while you are in public, and you don't want others to hear what you say? Or in a noisy place where you can't hear the other person on the phone? How to make your voice heard by the other person on the phone exclusively?
Maybe we can make some design that allows your voice only to be received by the phone, and the phone can also filter away noise other than your voice.
The second one is very useful! For outdoor parks, I think this can be accomplished by a camera at a high place and simple image recongnition
