Wireless digital menu system allows you to order food without human contact.I knew a couple of people who would love this idea - ordering food from a menu by using a wireless digital pen to scan barcodes, which then sends your order to the restaurant's kitchen without your having to speak with anyone. The Deli Touch pen by Taraoka is essentially a camera that reads barcodes embedded in the pictures on a menu and sends them to a printer in the kitchen where the order is filled.

Of course, without a robot, a human being would be necessary at some point to actually bring the food out to you, no? Then there's the pesky business of having to pay for the food, though I would think that could easily be automated too. If this idea catches on, think of the whole new industry that could develop to serve the socially phobic.
