Seems like I saw some news last year about the development of a new device - phone, projector, internet link all together in one thing. You project the keyboard or screen on any flat surface, similar to the OP.
The device also had a bar code reader which could scan items at the store, look them up on the web and display information about them - nutritional content, prices at other stores, etc.
Or did I dream that?
