Noriko-san

If you sleep on the bus or train you can buy this. It's a sleep mask called the Noriko-san which has a scrolling display on it to tell people where your stop is so they can wake you up at the right time. It was made by Pyocotan (an inventor from Japan). I can't find a site where you can buy it but I did the find the site of the inventor:
