FIELD: information technologies.
SUBSTANCE: invention is related to functioning of video presentation systems, namely to methods for organisation of interaction between user and presentation system by means of radiation device and device that performs recording and analysis of speech. This result is achieved due to processing of obtained voice command parallel with processing of confirmation light signal. At the same time light signal used is projection of light image to presentation screen from pre-established set of reference images, for every of which an association is pre-established with one of voice commands included into pre-established set of commands. In case when confirmation light signal is recognised by control device as matching with reference image, voice command is converted into command for computer and is performed.
EFFECT: higher accuracy in system performance of maximum number of user-performed operations with demonstrated video images.
