Robot Guides Subway Rider In London (Jul, 1933)
Twirling a dial helps subway riders find their way, at a self-service information booth just opened in London, England. To inquire how to reach any point in the city, the traveler sets the dial according to a printed list of instructions. The device then informs him of the place’s location, the exact fare required, and the number of the platform from which the appropriate train leaves.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
