Human contrast sensitivity function research and human vision model evaluation based on the ocular microtremor[1].

The innovative method is based on the orthogonal pair of eye movements – ocular microtremor and drifting. As the result of research, tremor modulation signal function is defined and evaluated for its effect on the human vision and environmental perception processes. The model describes the excitation threshold for central and peripheral vision in a wide range of external conditions – adaptation brightness, angular dimensions and frequency, grating angular size, test stimulus shapes and test stimulus presentation timings[2].

The model efficiently determines visual data structure and redundancy and estimates how partial distortion or information loss may affect the information understanding and its role in the decision making process[3]. It is possible to handle the full range of environmental conditions without additional tuning.

Research calculations show that this method is highly correlated and the model is potentially suitable for the early diagnosis of functional and professional diseases as well as controlling human fatigue and preventing overstrain.
