Pico projectors are an easy way to increase the screen real estate of your mobile phone, but what if you’d rather not carry one around in your pocket or bulk up your phone’s slim profile with a slip on solution? Well, a team of intrepid researchers may have come up with an elegant solution to your problem that can work with any smartphone and external display: VIRTUAL PROJECTION.

A team of researchers has come up with a way to virtually project a smartphone’s screen onto nearby external displays.

Smartphones have become so powerful that there are times when it would be great to be able to easily hook into external displays to share media, collaborate or just give your eyes a break.
Carrying around a selection of video cables or a pico projector doesn’t quite seem like the solution.
Taking a leaf out of the “you can’t do that!” scenes from many a movie, a team of researchers has come up with a way to beam a smartphone’s screen onto any nearby external display.
In augmented reality fashion, the system relies on tracking where the phone is being pointed using images from its camera.

Pick a screen, any screen

These images are then compared to constantly updated screenshots taken from connected displays by a central server, Screen contents can then be locked in place on the external display and further manipulated from the phone – whether that’s zooming in on a photo, using the phone as a media remote for video or navigating on a map.
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, allowing the system to work out which screen you’re pointing your phone at, where on the screen and at what angle.
. It then replicates what’s on the handset’s screen, while allowing you to add multiple image windows and position and rotate them as you see fit.Allowing the system to work out which screen you’re pointing your phone at, where on the screen and at what angle.
 Additionally, multiple users can collaborate and virtually project pictures or videos onscreen at the same time.You can watch the virtual projection demonstration video which shows the impressive results.
More than one phone at a time can project its contents onto one display, and this is one demonstration that we think could really have some potential.
