#1855: SpinSign

Astronauts on the space station have to live with no real definition of ‘up‘.

Today’s invention is to replace each of the many signs on board by a small, square electronic display. These displays would have a camera on board with face detection capability.

On spotting the face of an astronaut, a sign would be able to orientate its text and graphical message to match the crew member’s current alignment.
