Together with Museum Vestsjælland, we have tried to redefine what a museum experience is, to attract new types of visitors, and to follow with the digital age. Augmented Reality (AR) gives a new dimension to the visitor experience and makes it possible to travel back in time and recreate landscapes, buildings, and physical objects. This type of technology is therefore ideal for communicating and exploring the history and cultural heritage. We have developed a scalable AR framework of tools for developing interactive guided experiences, interactive narratives, and games. Tidslommen now contains several AR experiences, which mediate history in a fun and engaging way.
