Researchers in Germany, Canada and the US may have come up with an elegant solution that can work with any smartphone and an external display: virtual projection.
The system works by using a central server that constantly takes screenshots of the external display and compares them with the images from the phone’s camera to track its location.
It then replicates what’s on the handset’s screen, while allowing you to add multiple image windows and position and rotate them.
Additionally, multiple users can collaborate and virtually project pictures or videos onscreen at the same time.
Personally I think your battery life will suffer the most, but in general it is a cool idea.
