Linked Open Data as universal markers for Mobile Augmented Reality Applications in Cultural heritage

Integrating the Linked Open Data (LOD) cloud in mobile augmented reality (AR) applications for cultural heritage is a topic that started to emerge more clearly in 2010, and there are already projects that have designed and implemented applications that are based in sources from LOD cloud and visualized with AR techniques, while others discuss the current limitations and challenges on this integration, and underline the future directions and capabilities. The majority of the above works relies on the detected geolocation of the user or his device by various sensors (GPS – global positioning system, accelerometer, camera, etc.) or geo-based linked data, while others use marker-based techniques to link various locations with labels and descriptions of specific geodata. But when it comes to indoor environments like a museum or a library where tracking the accurate user’s position and orientation is far more complex, or unprepared environments without any kind of marker-based tracking methods like the use of radio frequency identification (RFID) tags, how can we define the link between user’s selected object of interest (OoI) and its description or metadata from the LOD cloud? This paper proposes a prototype which is based on image identification and matching between frames from the user’s camera and stored images from the Europeana platform, that can link the LOD cloud from cultural institutes around Europe and mobile augmented reality applications in cultural heritage without the need of the accurate user’s / device’s location, and discusses the challenges and future directions of this approach.
