In terms of complexity, it's far from being classified as a 'robot' or robotic application - it's way too simple. Yet the new toilet guidance signs being rolled out in Japan do give a taste of the future.
The signs include maps showing the rest room layout, carefully positioning each individual toilet stall and urinal. And they play spoken instructions telling you how far to walk and what turns you have to make to reach your destination.
This particular rest room sign, captured by Gary Wolff - a long time Japan resident and actor, is at Chofu station. I've seen a few others, including one in Shinagawa that incorporates LEDs in the sign indicating which stalls are currently in use. Welcome to a brave new world...
