The answer is: not very. Hamlet Au describes his conversation with a “robotar”, a computer controlled avatar and chatbot. He was mostly impressed by the nonverbal movements the helper bot made – she turned in his direction, for example – but there are some bot applications/services available today which allow these things (Pikkubot for example). I should tell him about it, but right now I’ve got to catch a movie 🙂
Justin Gibbs wrote an interesting article about NPCs and their role in our future digitized life and I couldn’t agree more with his thoughts.
