I agree whats been said here. I do think this thing could be developed further, but it has a long long way to go. I'm guessing that all the items in the presentation were carefully selected. The machine would have been programmed to recognise that aprticular type of plane ticket, bog roll, etc. Ina real life situation that is going to be a hell of a database which would need constantly adding to, or maybe some sort of futuristic intelligent database? I also noted that the student had a laptop open ont he table... Wether this was to sort the video for the presentation or whether it was being used to host the program I am not sure. If this things is going to rely on a server connection then communication technology may have to develope a bit first. The one thing that did make me smile is that somebody has finally found a use for those crappy little LED projectors!
