In this computer-generated image made available by Royal Philips NV, Monday, Nov. 18, 2013, an LED sign in a carpet indicates an exit in a fictional hotel environment. That option is on its way as two European companies, Philips and carpet-maker Desso have developed a system in which colored LEDs are combined with specialized carpets to make tailored hotel signs or directions to airport boarding gates that appear underfoot instead of on walls.
