This is really interesting and might be a great alternative to the projector type systems.
Phones now can share their screen to a nearby TV. So you could mount this, add a mouse via bluetooth to your phone, share your phone screen to a nearby TV and not be limited to looking at this on the small screen. You could use the mouse to interact with the phone. (Well, I know Ipads don't like the bluetooth mouse, I am not sure about IPhones. My Android can have a full keyboard and mouse attached wirelessly.
This also would work if you could project the phone screen to a project pointed at the table like the other projector based systems, except this system could actually read the table via the phone camera and then interact with the AI. Of course the software would have to deal with the camera reading what the projector was projecting to the table and what is really on the table.
Now if I can only get Jennifer's voice saying "Split the Wicket" out of my head. I did not like that. If she could have sounded either more excited or said it in a slower, softer, sexier voice, well, that might have worked for me.
