Design concept and prototype for an augmented reality based virtual preparation laboratory training in electrical engineering

There have been numerous studies so far highlighting the potential of Augmented Reality (AR) in different educational domains and its impact on learners regarding their increased motivation, improved learning, concentration on the topic etc. Ever since high-end AR applications could be used on smartphones, this technology has become suitable to be used in many formal and informal learning environments and educational institutions, beginning with Arts courses in preschool over Biology, History, Chemistry, Physics etc. in K-12 and universities as well as in vocational schools ([1], [2]), e.g. for assembly trainings [3]. However, less research has been done regarding proper educational design principles and guides identifying the learning-promoting characteristics as to their efficacy in an AR environment ([1], [4]). Particularly there is a big lack for design concepts in the field of preparation and accompanying tools for laboratory work, since current studies are only extending real papers or books with additional links, videos or static 3D models (e.g. [5], [6]). Hence, this paper investigates and focuses at a design concept for mobile device based AR application (App) to acquire and deepen practical skills in dealing with electro-technical laboratory equipment and components. In a previous paper, the potentials and limitation of AR technology regarding engineering education with a special focus on laboratory work have been investigated to avoid common mistakes in the design concept.
