Article deals with the possibilities of interaction in virtual reality (VR) systems with application to disabled persons. Using these technologies and appropriate learning methods can improve, accelerate and facilitate the learning of disabled children. For this reason, further development is directed to extend the interaction in VR systems (specifically CAVE LIRKIS). There are many inputs and interaction options such as keyboard, mouse, gyroscope sensors, EEG and others. Due to needs of handicapped people, their flexibility of movement it is necessary to consider the applicability of input devices. The MYO armband was selected as the first and most suitable device to work on further development of interaction in the virtual environment.
