Layar is a Dutch company specializing in augmented reality (AR) technology. While their website, http://www.layar.com, is no longer actively maintained and provides limited information, historical data reveals Layar's focus was on creating AR experiences accessible through mobile devices. Their platform allowed users to overlay digital information onto the real world through their phone's camera, essentially bridging the physical and digital realms.

The core of Layar's technology was a software platform enabling the development and deployment of AR applications. This involved creating digital "layers" of information that could be accessed by pointing a smartphone or tablet camera at specific locations or objects in the real world. These layers could include text, images, videos, 3D models, and interactive elements, enriching the user's experience with contextual information and engaging interactive content.
