MIXED REALITY AS NEW OPPORTUNITY IN THE PRESERVATION AND PROMOTION OF THE CULTURAL AND HISTORICAL HERITAGE Irena Peteva, Stoyan Denchev, Ivan Trenchev University of Library Studies and Information Technologies (BULGARIA) Abstract This paper presents the main conceptual framework of the first stage of realization of the scientific project “Application of the mixed reality in the training and promotion of the cultural heritage in university information environment”. The aim of the project is to show the possibilities of the virtual and added reality through the so defined mixed reality in training and promotion of cultural and historical heritage for the benefits of the users. The presentation of the cultural and historical heritage based on the Augmented Reality (AR) technology will enable visitors to interact with the content in an intuitive and exciting way. It is a technology that expands the perceived reality at the expense of complementing the visible and tangible world with digital information in real-time. In the context of modern trends for socialization of cultural heritage, the role of information and communication technologies is emphasized because it creates new opportunities for access to cultural values in regards of national policy and the very point that is a priority for the European Union. This policy is part of the global doctrine of sustainable development, which is based on the three basic principles: economic development, social justice and environmental protection, including cultural heritage. As a result of the investments made for the socialization of the cultural heritage, the development of the regions is stimulated through economic activities related to the exploitation of cultural resources for cultural tourism, the development of the regions and the human resources. In this sense, the cultural heritage plays an increasingly important role in the regional development of Bulgaria. The process of socialization is also a consequence of the increased educational level of travellers. The data given by the European Commission, quoted by some experts from the European Commission, show that nearly 60% of Europeans are interested in the cultural aspect of tourism and especially in issues related to cultural heritage. This is what makes tourism a powerful tool of cultural exchange worldwide. By using cultural and natural assets of the environment, cultural tourism promotes and “maintains the collective memory of society”. Keywords: mixed reality, education, cultural and historical heritage. 1 INTRODUCTION AND THEORETICAL FRAMEWORK The promotion of the cultural and historical heritage through information technology is an extremely efficient formula for the proper use of technology in the process of perception and study of human cultural heritage. The opportunities offered by modern technologies allow a more attractive and correct way to enrich the access options to the elements of cultural-historical heritage. 3D modeling is an opportunity for a more efficient documentation and socialization in modern concepts for the preservation of cultural heritage, where modern technologies are applied, and the highest possible preservation mode is achieved, as well as their studying and promotion are done [1], [2], [5] [7]. Today, researchers possess an increasing amount of available data so they need properly to adapt to the scientific methodologies. The use of 3D digital technology helps archaeological reconstruction in many ways [3], [4], [6]. The essential issue is that digital tools provide a means of standardizing and comparing individual data sets that match visual material together with geographic, textual, qualitative architectural and quantitative information. As a result, the three-dimensional models allow the researcher to holistically explore the city as a complex phenomenon, including spatial, its material and cultural determinants [8], [9]. Preservation of cultural heritage is a systematic process of search, study, identification, documentation, registration, conservation, restoration and socialization. Hence, protection of cultural heritage presents a system of measures ensuring its preservation in the Interest of Society.
