## 1 Introduction  
The first mention of Bosnia dates from around 950 A.D., when Byzantine Emperor [PERSON] [PERSON] mentioned a country called \"Bosona\" in chapter 32 of his article \"De administrando imperio\" [1]. The Bosnian medieval kingdom was established in the 11 th century and dissolved when the Ottomans conquered the Balkans in the 15 th century. In the 19 th century, Bosnia and Herzegovina (BH) was occupied by the Austrian Hungarian Monarchy, and after WWI it became a part of the Kingdom of Serbs, Croats and Slovenians. The first Yugoslavia was a monarchy established in 1929 and after WWII it became the Socialist Federative Republic of Yugoslavia, where Bosnia and Herzegovina was one of the six Republics. After the referendum in 1992, Bosnia and Herzegovina became an independent state again and was recognized by the United Nations. During its turbulent history, traces of different cultures, nations and religions have remained in Bosnia and Herzegovina. BH cultural monuments date from Neolithic times until the recent war in the 1990s. Despite all the conflicts and dominions, life in this country has always been based on mutual respect, so that cultural diversity has survived until today. Digital technologies have brought many possibilities to preserve and present this treasury of cultural heritage. Using Virtual (VR) and Augmented Reality (AR), cultural monuments are being reconstructed in the form of 3D models and these 3D models are now inhabited by historical characters who tell stories about events and life in the past. Our research within the Sarajevo Graphics Group has been taking internet users and cultural monument visitors to time travel into Bonsian history over the last 15 years. In this paper we present an overview of our recent projects which exploit the potential of VR and AR technologies in enabling the users to experience the past. The high immersivity of VR headsets easily transfers the users into a different place and time, but they need to be offered content that can use the potential of this technology and recreate life in virtual environments. VR video overcomes classical video as a medium and breaks the rules of film language and grammar. The viewer is now placed in the middle of the scene and can freely choose his/her insight, so shot composition rules do not apply. The new directing methods need to enable following the plot while being free to turn around and look in different directions. That means that the user's attention should be captured in new ways. Our research group has been working on applications of digital technologies to cultural heritage preservation and presentation for 15 years. The research problem we defined is to familiarize museum visitors and Internet users with Bonsian cultural heritage through Virtual and Augmented Reality, combined with interactive digital storytelling. There are many high quality virtual reconstructions of cultural monuments that lack the feeling of life in the past [2]. The aim of our methodology is to improve the edutainment value of digital content for museum exhibitions and digital cultural heritage applications, introducing actors playing historical characters as narrators and recreating life in virtually reconstructed cultural monuments. Our experience with the use of these technologies in cultural heritage presentation will be shown through descriptions of four projects. Firstly, we will present the VR documentary \"Nine dissidents\", which deals with the problem of intellectuals persecuted in the socialist Yugoslavia for their dissent with the regime. As this is the first BH VR film, we will describe what we learned during the production and what elements of the new film language grammar we defined. Then we will present the Old Crafts Virtual Museum in order to show how the intangible heritage of carts in Old town Sarajevo can be preserved and presented using Virtual Reality.
