Abstract:In this paper, we try to present the problems of the modern approach to treating various phobias. Virtual environments created by virtual reality (VR) tools can help to make the treatment of certain types of phobias more efficient. Attention to this form of phobia treatment with the help of VR is on the rise in the world, so we are also monitoring its development, as well. Our paper introduces the necessary hardware and software that has been piloted in our department, but also methods of creating virtual environments, models and application designed for medical therapies of patients. In our work we have searched for and tested the following methods for creating virtual environments: A) modelling using computer graphics, B) modelling animation using animation programs, C) taking pictures of static objects and scenes, D) filming moving objects and scenes using classic video or special scanning techniques to create 360 ∘ panoramas or E) any combination of these methods.

Virtual, augmented and mixed reality (VR, AR and MR) infiltrated not only gaming, industry, engineering, live events, entertainment, real estate, retail, military, etc., but as surveys indicate, also healthcare and education. In all these areas there is a lack of software development experts for VR, AR and MR to meet the needs of practice. Therefore, our intention at the Department of Computer Science, Faculty of Natural Sciences, Matej Bel University in Banská Bystrica, Slovakia, is to focus on the education and enlightenment of these areas. The aim of this article is to show the role of interactivity in different VR applications and its impact on users in three different areas: gaming, healthcare and education. In the case of one application of Arachnophobia, we also present the results of the research using a questionnaire.

Technologies in the current world are constantly changing. These changes are also reflected in teaching process. Computer Science subject uses mostly programming language Scratch in Slovak schools. We wanted to try out a new tool for pupils as a way for programming and STEM educationmodular and programmable drone Airblock. In this contribution we wanted to present this drone which we think is suitable for teaching programming. Drones are very popular among people and that was the reason why we think drones can be used as a motivational tool in order to teach programming at schools. This was done by the extracurricular activity at the Matej Bel University and the pupils were from lower secondary schools in Banská Bystrica, Slovakia. The pupils developed many buttons with different behaviours. The Airblock drone could fly without pre-programmed buttons. The subject matter of this article is a presentation of robotic toyprogramming of the flying drone Airblock suitable for teaching programming.
