The Freespaces-scanner
An Invention of Fabian Gutsche
The Freespacescanner is an invention that is made to help travelers find a free space in the underground or in other public means of transportation, in the form of a flatscreen TV that shows a 2D image of the blueprint from the public mean of transportation and sets of laser-barriers that replace armrests. It works as follows: when someone sits down on a seat he automatically breaks the laser-barrier. The laserbarrier sends a signal to the main computer in the flatscreen which then Xes out the space in question.
