Everyday computer graphics

If AR becomes universal, then we can use it for casual, small things that will make our daily lives a bit easier. One of the more logical uses for AR is communication. For example, as many authors have observed, it would be handy to leave notes for each other in cyberspace, yet attach them to physical objects or locations. I suggest some of the applications that I´d like to have available for personal or individual use on an everyday basis. They communicate to users without text. Instead, graphics do all the work.
