4D virtual reconstruction of white bastion fortress

White bastion fortress has been standing in defense of Sarajevo since medieval period. In time it was changing together with various dominations upon the city. 4D virtual presentation aims to display the historical development of this cultural heritage object through digital storytelling combined with interactive 3D models of the Bastion in various time periods. These models contain digitized findings from the site and their 3D reconstructions. In this paper we present a new method of interactive digital storytelling for cultural heritage and its initial user evaluation.

Visualization and multimedia presentation of cultural heritage

Understanding the past is one of the key factors of human culture. Cultural heritage contributes to the preservation of collective memory. It is difficult to imagine the original appearance of monuments while observing their archeological remains. Digital technologies are an efficient tool for visualization and multimedia presentation of cultural heritage. This paper describes the use of these technologies through the workflow of the White bastion 4D visualization project, from collecting information, through 3D modeling and texturing to interactive web implementation using the most advanced web 3D technologies. We discuss the advantages and drawbacks of each technology for this particular purpose.

Enhancing museum exhibitions with interactive digital content: Sarajevo city model interactive

Digital technologies prove to be a very efficient tool in enhancing museum exhibitions. In this paper we describe the Interactive Sarajevo City Model project. It is an application which shows a digital version of Sarajevo old town physical model which represents the appearance of the city during the Ottoman period. Instead of pointing out particular cultural heritage objects in the physical model, the curators and museum visitors can click on the corresponding info points in the application and obtain the information about those objects and their history. The paper presents the application development workflow together with some issues within the standalone implementation and user perception of such enhanced museum exhibition.

Guidelines for interactive digital storytelling presentations of cultural heritage

Interactive digital storytelling becomes a form of information presentation in many fields. Its application spans from media industry through digital cultural heritage, serious games, information visualization to contemporary theater and visual arts. In order to develop a new digital storytelling methodology hyper-storytelling, we engaged a team of multidisciplinary experts from computer science, visual arts, literature, film directing, psychology, communicology and human computer interaction. In this paper we present the first findings of this team in form of guidelines for interactive digital storytelling presentations of cultural heritage.

Usage of Android device in interaction with 3D virtual objects

Implementation of natural interactive online 3D visualization is difficult process. To keep people interested in virtual heritage the new ways of immersive interaction must be developed. This paper presents a solution for natural interaction with 3D objects in virtual environments using Android device over WiFi. It describes the principles and concepts of functioning of individual components as well as the principles of operation after the integration of all components into a single software solution.

LiDAR based terrains for virtual cultural heritage applications

Virtual presentation of cultural heritage has shown a great potential in preservation of collective memory. The level of immersion that the visitor feels in a virtual environment is one of the key factors for the quality of his experience. Terrains are the most authentic elements of cultural heritage sites, as they rarely have been significantly changed through time. In this paper we explore the use of LiDAR based terrains in interactive virtual cultural heritage applications, considering the advantages and drawbacks of this approach. Our case study is the virtual presentation of the Early Christian Basilica in Cim near Mostar, created for the interactive exhibition “Keys to Rome”.

Web application development with component frameworks

This paper describes development of dynamic web application using web frameworks based on web components. The paper considers several existing open source Java web component frameworks. Then, the paper provides basic features of the analyzed web frameworks and represents their main characteristics. To give an idea of which framework might use, the paper compares all analyzed web frameworks, and summarizes them and gives an overview of all their the most important characteristics.

Temporal and Spatial Data and Default Assumptions in Dipsy-E Systems

DIPSY-E is software environment for development of real-time expert systems. Since time varying events or space distribution dependent objects appear in these systems, the temporal and spatial data is included in DIPSY-E. Problems of incomplete information and unreachable data in such systems can be solved by means of DIPSY-E default assumptions mechanisms.
