Information technologies impact our daily life in many significant ways. Nevertheless, there is a lack of availability of some technologies to the wide public caused by their location and price. This insufficiency seems to be even bigger for disabled people. LIRKIS laboratory of Technical university of Košice proposes solutions in education of these people and develops technologies of virtual reality...

The aim of this work is to highlight the use of semi-immersive virtual reality in educational process. Part of the effort is explanation of virtual reality systems considering immersion and human-computer interaction. For implementation of such a system was needed to define requirements to enhance productivity during education. Described solution is based on virtual workbench using touch user interface...
The aim of this article is to describe the security field user interface for persons with reduced safety awareness. The introduction is a description of some related projects. Consequently, in this context, describes the possibilities of using GPGPU technologies and their implementation in the field of user interfaces with a focus on software ergonomics.
This work represents a new solution for augmented reality systems for desktop computers with Windows OS and mobile devices specifically with Android OS. It describes and explains the basic aspects and principles of augmented reality, and at the same time it analyzes problems of the actual implementation of such systems. After this analysis, two separate applications are designed for desktop computers...
Visualization of three-dimensional environments is a very complex task when one aims to achieve high fidelity. There is a plenty of hardware supporting two-dimensional visualization presenting height and width of the objects of the 3D scene. The illusion of the depth can be multiplied by using some of the known stereoscopic projection techniques. This paper presents and compares three of them: colored...
Digitization of real objects into 3D models is a rapidly expanding field, with ever increasing range of applications. The most interesting area of its application is in the creation of realistic 3D scenes, i.e. virtual reality. It can be used in the entertainment industry, design, architecture and scientific research. This paper provides a brief summary of current 3D scanning technologies, deals with...
This paper deals with a support tool for an automation of simulation of Coloured Petri nets and selected simulation experiments conducted with the aid of the tool. The tool is called CPN Assistant, it has been developed at the home institution of the authors and cooperates with the CPN Tools software. It allows to run and manage multiple customized simulations in a network environment. The experiments...
This paper describes the process of preparing panoramic pictures for the presentation module of our 3D city agglomerations visualization system. First, script creation is discussed, which allows the smooth redraw of model given by the transition path. Second part of the paper deals with rendering settings for photorealistic outputs. Third part is about using network rendering for speeding rendering...
This paper informs about simulation used in education and training process. The focus is on infantry and crowd behaviors on constructive simulation centers that are established on Simulation centers in Slovak Armed Forces. Training audiences taking participation on this simulation type are military staffs and civilian crisis management staffs. Simulation system is based on the software named OTB (OneSAF...
This paper deals with graph theory application in large-scale geographical data searching and visualization. We present a comparison of two path-finding algorithms of graph theory, i.e. blind-search and A* algorithm, that results into the selection of the second one for implementation within a geographical information system. The main goal is to process the terrain map representation in the form of...
