- small projector

Published by Victoria Woolaston: EDT 11: 47 on March 4, 2014 | update: EDT 11: 48 on March 4, 2014, Microsoft has an answer if you want to rebuild a cinema in the living room or turn your bedroom into a karaoke bar.
Its SurroundWeb prototype projects the screen from the computer to the wall of the room, including browser tags, maps, documents, videos and photos.
The system scans the layout of the room using small projectors and sensors, including furniture, objects and people, to ensure that the web page is not distorted.
It also maps mouse clicks to gestures using the Kinect camera.
This means that the user can put their hands on the position of the link on the wall, and if they mimic the push link, the SurroundWeb system will recognize it as a mouse click.
Examples given in research papers include videos projected from PC to large walls, karaoke lyrics displayed above music videos played on TV screens, or photos with windows instead of walls.
SurroundWeb, like Microsoft Illumiroom technology, was announced on last January.
The difference is that Illumiroom uses sensors and cameras to project images in the game onto the wall, allowing players to immerse themselves in the land of fantasy.
At present, this technology is just a proofof-
Designed and tested by Microsoft Research, the company has yet to announce its plans to release it to the public.
Instead of revealing exactly how the system works, Microsoft said:
Our prototype can scan the projected surface of the room in about a minute, thus presenting an immersive number
The web room is displayed at a speed of more than 30 frames per second, with a maximum of 25 screens and a maximum of 1440x720.
This creates what the company says about the room skeleton.
The designer also stressed that the system is safe and cannot detect faces in the room or read documents, such as bills on the table.
When the company announced the Illumiroom last year, the company said that the system increased the area around the TV screen through projection visualization to enhance the traditional living room entertainment experience.
Surroundweb uses the Kinect camera in a similar way to blur on-
Screen content and the environment in which we live allow us to combine virtual and physical worlds.
Kinect sensors and Kinect Fusion software can track force and motion very accurately.
It can also be used in SurroundWeb technology to identify furniture, or to merge chairs and tables directly into a browser, or to cover them up by adjusting the video output to make the item look invisible.
Microsoft said: "Our system can change the look of the room, cause obvious movement, extend the view and bring a whole new experience.
