Eye Movement Analysis System in Relation to Biomechanical Perturbations
Eye Movement Analysis System in Relation to Biomechanical Perturbations

Summary/Abstract: Behavior in its totality has apparent cognitive and observable findings, such as language, gesture, body, head, upper or lower limbs, facial and ocular expressions, etc., or subconscious, physiological, inappropriate such as micro-modulation of heart rate and physiological parameters, modification of ideo-motor activity etc. Analysis of eye movements is an objective way of assessing the state of concentration and attention in cognitive processes. Fundamental and applicative research in this field has highlighted a number of defining aspects of the cognitive process that relate to the different positions and movements of the eyeball. In this regard, a portable eye analysis system, correlated with biomechanical disturbances induced by the posture of the subjects was developed in the paper. The system is used to simulate synchronized postural disturbances at the same time as recording changes in human body stability and eye movement changes. The second part of the paper describes the experimental system; the sample of subjects is chosen according to the criteria established by the analysis procedure and also the recording procedures under stable and reproducible environment are developed. In the final part of the paper, results from applications and some conclusions are presented. Experimental application can determine the mode of response of eye movements in relation to the type and level of biomechanical perturbation. This response defined by the eyeball eye movement parameters can characterize the state of focus, attention or involvement by assessing behavioral coefficients. The results of the determinations are at the same time a mechanism of cognitive training and evaluation of adaptability capacity to the conditions of action of random perturbations.
