Last night Sally and I sat down for a chat with Philip K Dick. Whilst it was no a seance, it was closer to that than to say Mark Twain Tonight. The Philip K Dick robot from Hanson Robotics (and others) features a very flexible and eeriely realistic face which seeks out people in the room (using facial recognition) to establish eye contact with them. He shutters and blinks as he thinks about how to answer your questions. Behind that blinking and shuttering is a program using latent symantic analysis (and indexing) to mine the entire works of Dick. [more after I get back]
