Netpage Internet Services is a software system and infrastructure which makes printed paper interactive. It has multiple manifestations, including digital pens, digital paper, and augmented reality interfaces, such as the Netpage mobile app. The app uses image recognition technology to recognise content on Netpage-enabled printed pages, and then serves up a “digital twin” of the recognized. The digital twin contains enhanced functionality such as the ability to share the page via social media sites (e.g. Facebook, Pinterest and Twitter), the ability to purchase products, watch embedded videos, follow hyperlinks, translate text, download and attach files, and other functionality.
