Layar is a free application on your mobile phone which shows what is around you by displaying real time digital information on top of reality through the camera of your mobile phone.
Layar is a global application, available for the Iphone 3GS, T-Mobile G1, HTC Magic and other Android phones in all Android Markets.
By holding the phone in front of you like a camera, information is displayed on top of the camera display view.
For all points of interest which are displayed on the screen, information is shown at the bottom of the screen.
On top of the camera image (displaying reality) Layar adds content layers. Layers are the equivalent of webpages in normal browsers. Just like there are thousands of websites there will be thousands of layers. One can easily switch between layers by selecting another via the menu button, pressing the logobar or by swiping your finger across the screen.
