Frequency-time features of eye movement when using the video-oculographic interface in ergatic system control problems
The paper is devoted to the development of the concept of the capabilities of video-oculographic interfaces in management tasks. The results of studying the parameters of human eye movement using a video-oculographic interface for controlling an object on a plane are presented. It is shown that in the course of the experiment, the number of errors and the number of subjects who did not perform successful control decreased from attempt to attempt, as well as the dependence of the ability of such control on the human temperament and working memory features. At high values of working memory, users make more sharp high-amplitude movements of the pupil with a period of up to 1.6 s, forming a control pattern, which eventually leads to more control errors and does not achieve the desired result. To a large extent, the results obtained are related to horizontal rather than vertical eye movements. The presented results will be useful for creating and applying human-computer interfaces in digital monitoring in the management of ergatic systems and can serve as a starting point for the development of high-speed oculographic interfaces with significantly broader functionality than the existing ones.
