Abstract: This paper describes the concept of virtual reality and the use of this technology in practice. The main part of the work is about reviewing the various stages of the development of a prototype system for interactive video management by means of an exercise bike. Systems, that are currently available on the market, are, due to their ease of use, closed units, for which upgrades are not possible or come at a great expense. The main advantage of the presented prototype, besides affordability, is a simple option to upgrade the system by adding sensors and/or modules; this allows us to extend the system in every stage of development. A low-cost computer (Raspberry Pi) is used as a processing unit, for calculating the speed of the wheel and sending this information to the control unit. The control unit processes the received data and sets the playback speed of the video clip accordingly. There is great potential for improvement on the developed prototype. Thus, ideas for further development are presented in the concluding section.

Abstract: In this paper, we describe the design of a visual interface of a mobile a mobile app for tracking nutrients and foods consumed by patients with Parkinson’s disease. The interface should enable the patients to recognize objects on the screen, easily perceive their function and interact with them thus providing an efficient way of entering the dietary intake data. The app has been validated by five patients and the preliminary results are encouraging.

Abstract: The aim of the article is to show how off-the-shelve equipment can be used to develop serious games for an affordable tele-medicine solution for Parkinson’s disease management. Two games have been developed aimed at assessing and training patient’s reach of upper limbs (using Kinect v2) and fine motoric skills of fingers (using Leap motion). The games collect player data in terms of score achieved and full kinematics of movement during gameplay. The data is stored online and made available to therapists and doctors through a secure connection. The games have been tested with patients within the Soča rehabilitation institute as well as at their homes.

Abstract: In this paper we present a novel integration of four remote collaboration modalities into an existing web-based medical data visualization framework: (1) visualization data haring, (2) camera view sharing, (3) data annotation haring and (4) chat. The integration of remote collaboration modalities was done for two reasons: for getting the second opinion on diagnosis or for getting a diagnosis from the remote medical specialist. We present an integration of these modalities and a preliminary evaluation by the medical expert. In conclusion we show that we are on the correct track of integrating collaboration modalities into the visualization framework.
