METHOD OF ASSESSING HUMAN OPERATOR ACTIVITY Russian patent published in 2025 - IPC A61B3/113 A61B5/16 G06F3/01 

FIELD: physics.

SUBSTANCE: invention relates to medical and technical field, in particular to software and hardware resources, which increase efficiency of people working at computer monitors with high load on visual analyser. Disclosed is a method in which a researcher selects a diagnostic program and/or development of useful skills of a human operator (HO) from a library of SHC, which contains means of video monitoring of HO actions in the volume of its working space. At the same time the SHC includes feedback means for automatic notification of the HO on violation of the correct mode of its operation. Feature is that solid or discontinuous video content with a given interval, which comes from the front camera of the software-hardware complex, is processed by the program of the complex with automatic recognition and analysis of the state of the eye region of the human operator. Software-hardware complex, fixing the position of the eyelids of the human operator, calculates each time interval of eye operation without closing the eyelids and sends a vibration, and/or audio, and/or video signal to the human operator in real time if this interval exceeds a given time correct operation of the visual analyser without covering the eyelids. Software-hardware complex calculates the average time index of the eyelid closure frequency of the human operator. Arithmetic mean time index or maximum number of errors when performing tests is used to determine the level of preparedness of a human operator to work effectively at the monitor. By analysing the data of different-time tests, the ability to train to work at a computer and the dynamics of change in useful skills is determined. Additionally, the SHC monitors the specified time interval of the human operator without moving the gaze from the monitor to the remote object. SHC sends vibration and/or audio and/or video signal, if this interval exceeds the preset time of operation of the visual analyser of the human operator without shifting the gaze to the distant object at the preset distance or fixation of the gaze on the distant object is less than the preset time in the program of the complex. At the same time, the SHC automatically corrects the time of signals by a given value depending on the total continuous or total daily time of the human operator at the monitor.

EFFECT: invention enables to determine quantitative values of HO in a wide range of space-time characteristics of tests; by comparing quantitative results of different-time tests, it is possible to determine dynamics of development of useful skills of HO.
