FIELD: physics, video.
SUBSTANCE: method of reducing the number of viewers withdrawing from a video image by monitoring the concentration of human attention on the video image can be used by advertisers to improve advertising effectiveness. The method comprises, at the moment of viewing an image, using a control device for inputting and/or recognising information, connected to a video image source, having controlled continuous-action parameters interfaced with human continuous action, and having an active/inactive state property; then based on the obtained data from the control device, monitoring continuity of presence of a viewer directly in front of the video image source, and launching further action of the program only in case of continuous presence of users (viewers). The used control device is any device which is physically close and constantly connected to a video image source (computer, video player, mobile device or any other video image source) and has an active/inactive state property specified by human action, with a state reading interval of not more than 100 ms.
EFFECT: method reduces the cost of one advertising exposure 5,5 times on average, which significantly saves the advertising budget.
