Maptor is an electronic map with high mobility in every sense of the word. It is a combination of a map and a (inbuilt) projector that throws a map of your current location on to any desired surface. This concept device is small to be worn around the neck and could pass off as a lipstick.

The Maptor also has an built in GPS system that is able to tract your location and provide the appropriate map. A big red arrow is used to point out your current location. The only key concerns seems to be if the projector can be used in daylight.
