Most have us have built in GPS in our cellphones, but if you do no like the weird small screen and would like to have a larger map, this portable map projector may be your answer. It is a concept developed by Jin-Sun Park and Seon-Keun Park whose original idea was to eliminate the need for paper maps. We are pretty sure when it comes to portability, this device called the MAPTOR will be hard to beat.
To see the map just point the MAPTOR to any solid surface. It also allows you to zoom in/out.
