Modern innovative applications for mobile phones are one of the means to attract the attention of visitors to local sights and preserve the cultural and technical heritage. The aim of the project was to develop a software solution for the production and handling of multimedia content that can be presented on site based on images captured by the camera of the phone. Solving such problems requires an interdisciplinary approach with an input from computer science, multimedia, archaeology and graphic design. The project was a cooperation between the Faculty of Computer and Information Science, the Theodosius Cultural and Educational Society (DT) from Vrhpolje by Vipava, and the Technical Museum of Slovenia (TM).
