Samsung has filed a patent for a virtual screen that would be projected by a cell phone or other portable device. Hot. The details basically explain why your current office looks like a blast from the past. Step into 2020, "When a signal is input from the electronic pen, the mobile terminal detects the originating position of the signal and its trail. The mobile terminal recognizes the detected trail as a character and generates a virtual screen with the recognized character."
I think I want one of these, but I also find it somewhat impractical.
