Book Description
This paper describes a video eye-tracking algorithm which searches for the best fit of the pupil modeled as a circular disk. The algorithm is robust to common image artifacts such as the droopy eyelids and light reflections while maintaining the measurement resolution available by the centroid algorithm. The presented algorithm is used to derive the pupil size and center coordinates, and can be combined with iris-tracking techniques to measure ocular torsion. A comparison search method of pupil candidates using pixel coordinate reference lookup tables optimizes the processing requirements for a least square fit of the circular disk model. This paper includes quantitative analyses and simulation results for the resolution and the robustness of the algorithm. The algorithm presented in this paper provides a platform for a noninvasive, multidimensional eye measurement system which can be used for clinical and research applications requiring the precise recording of eye movements in three-dimensional space.

Book Description
This monograph describes the findings of spaceflight research related to spatial orientation, sensorimotor coordination and mental function. Exposed to the microgravity conditions of spaceflight, the human experiences a variety of physiological and psychological problems, which are presented here. Recent findings of sensory motor research in space are depicted and their benefits for life on earth discussed. The examination of the vestibulo-oculomotor system for example has led to the development of innovative devices for the measurement of three-dimensional eye and head movements. These devices are currently employed in Earthbound applications such as eye laser surgery. The book is written for students and researchers in neurosciences, biomedical engineering, for neurologists and psychologists as well as for persons wanting to know more about biomedical research in space and its application on earth.

Book Description
The book presents high-quality research work on cutting-edge technologies and the most-happening areas of computational intelligence and data engineering. It includes selected papers from the International Conference on Computational Intelligence and Data Engineering (ICCIDE 2018). The conference was conceived as a forum for researchers from academia and industry to present and share ideas and results and allow them to develop a comprehensive understanding of the challenges of technological advancements from different viewpoints. As such, this book helps foster strong links between academia and industry. It covers various topics, including collective intelligence, intelligent transportation systems, fuzzy systems, Bayesian network, ant colony optimization, data privacy and security, data mining, data warehousing, big data analytics, cloud computing, natural language processing, swarm intelligence, and speech processing.

Book Description
The 19th-century pioneers of motor physiology — Helmholtz, Hering, Fick and others — used the mathematics of motion, known as kinematics, to describe the laws of human movement and to deduce the neural control principles underlying these laws. After long neglect — partly due to limitations in stimulation and recording techniques — the kinematic approach is now resurging, fortified with modern computers and electrophysiology. New developments in recording techniques, as well as an improved understanding of the complex control properties of three-dimensional movements, have led to a flood of new research in this area. The classical laws of Donders and Listing have been confirmed and generalized, and computer simulations of the neural control of three-dimensional movement have been developed and tested. In this book, some of the world's leading scientists of motor control discuss how the brain represents and transforms the kinematic variables of movement. Background chapters explain the basic concepts — non-commutativity, redundancy and the classical laws — and their application to normal function and motor disorders, and shorter articles describe current research. The contributions are based on presentations at a symposium held in Tubingen in August 1995. The wide scope of the book should enable researchers to gain an overview of current research, but should also help newcomers to the field to get a good understanding of the questions and problems involved in three-dimensional movement control.
