Modeling And Application Of Head And Eye Movement Based On Vestibular Function

In recent years, with the continuous development of human technology, people are more interests in their own mysteries. Brain is the most complicated structure of the human body, the related areas of research attract more and more attention. The system of head-eye movement is the adaptive regulation system to body’s own acceleration. The vestibular system is the core of the system of the head-eye movement.The vestibular system is not only a biological reflection organ of their own state of motion, but also an organ of feeling space state. The information of body’s own state of motion is passed through the nerve to the vestibular system, and then through a series of vestibular system’s processing. It forms a variety of neural signals or excited passed to the various organs of the need for such information. Human’s head-eye movement is the application of a vestibular system function. The information of body’s motion is delivered to the eye through the vestibular system, and lead to the eye movement, such as tremors, rotation. Head-eye movement research can be applied to many areas, for example, the vertigo detection pilot status monitoring, illusion of detection and so on. This review focuses on the head-eye movement system model, with integrating of previous research vestibule and semicircular canals, puts forward to simulate the human vestibular system of the human body acceleration process according to the human body acceleration. The details in the paper are as follows:First chapter introduces some concepts of the head-eye movement, several models of eye movement briefly, and eye movement model used in this paper. Finally, the significance of the head-eye movement research will be introduced. The application of the head-eye movement research includes dizziness detection, physiological system detects illusion detection. Second section briefly outlines some mathematical tools that will be used in this paper, including fractional calculus, M-L function, rotation matrix. The rotation transformation matrix is the most important mathematical tool in the three-dimensional. For the three-dimensional rotation, there are three methods:quaternion, euler angles and rotation transformation matrix. This section reveals the advantages and disadvantages of the three methods, and the reason why this paper to be a transformation matrix to represent the rotation.Chapter II introduces a head-eye movement system physiology research background. The first section introduces the vestibule, semicircular canals and their physiological structure, and the physiological response process of the head-eye movement, making theoretical foundation as well as the feasibility of the head-eye movement clearly. For example, turn the head right, the eye response to the head of the right turn. In the second section it introduces some eye movement researches and some mature products on the market.Chapter III introduces the research about the vestibular system. Vestibular organ is mainly reflected the body directly acceleration, semicircular canal system primarily reflect body rotation. For vestibular organ, first introduce the Grant et al’s research and analyse the shortcomings. Then Haijun Su et al improved solutions of Grant et al’s model, and made it a high-precision solutions. Based on the solution we get the scope of some of the important parameters, which affect the model. Semicircular canal response to the rotational movement of the human body, and Buskirk et al made a huge contribution in this field. The results of their reaserch will be presented in the second quarter. After anlalysing the shortcomings of the model, Ming-Yu Xu, Haijun Su model will be introduced.Chapter IV introduces the overall model of the head-eye movement model for smooth tracking movement of the eye, then the system modeling for head and eye movement system.Head-eye movement system is a whole system, the previous research of head-eye movement system are mostly theoretical, and mainly focuses on a particular aspect of the system, lack of practical application of practice,and do not integrate the model to the overall research head and eye movement system the applications relatively narrow.Thesis for the overall modeling of the head-eye movement system, considered from the whole head-eye movements can be used in many fields, such as dizziness detection.Chapter V firstly given out a simple simulation, make sure some parameters. then the actual measurement eye data with model simulation results were compared with the results expected to prove the validity of the model.Chapter VI the simulation results proved the validity of the model, and proposed model shortcomings, limitations finally, and make the way and direction of the improvement in the future, the model further development, the direction of the application more clearly.
