Battle of Stiklestad: supporting virtual heritage with 3D collaborative virtual environments and mobile devices in educational settings

3D collaborative virtual environments (CVEs) have been widely used for preservation of cultural heritage, also in an educational context. This paper presents a project where 3D CVE is augmented with mobile devices in order to support a collaborative educational exploration of a famous historical site in Norway, where Battle of Stiklestad took place in 1030. This system can be used by both local and distant learning communities, working together towards a common goal. The paper presents a background for the project and a set of requirements for an augmented system, describes the corresponding design and outlines the technical implementation of a hybrid prototype.
