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.
