We make 3-5 eye movements per second, and these movements are crucial in helping us deal with the vast amounts of information we encounter in our everyday lives. In recent years, thanks to the development of eye tracking technology, there has been a growing interest in monitoring and measuring these movements, with a view to understanding how we attend to and process the visual information we encounter Eye tracking as a research tool is now more accessible than ever, and is growing in popu...

Observing the User Experience: A Practitioner's Guide to User Research aims to bridge the gap between what digital companies think they know about their users and the actual user experience. Individuals engaged in digital product and service development often fail to conduct user research. The book presents concepts and techniques to provide an understanding of how people experience products and services. The techniques are drawn from the worlds of human-computer interaction, marketing, an...

'Seeing' happens effortlessly and yet is endlessly complex. One of the most fascinating aspects of visual perception is its stability and constancy. As we shift our gaze or move about the world, the light projected onto the retinas is constantly changing. Yet the surrounding objects appear stable in their properties. Psychologists have long been interested in constancies, exploring questions such as: How good is constancy? Is constancy a fact about how things look, or is it a product of ou...

Daily rhythms are a ubiquitous feature of living systems. Generally, these rhythms are not just passive consequences of cyclic fluctuations in the environment, but instead originate within the organism. In mammals, including humans, the master pacemaker controlling 24-hour rhythms is localized in the suprachiasmatic nuclei of the hypothalamus (SCN). This circadian clock is responsible for the temporal organization of a wide variety of functions, ranging from sleep and food intake, to physi...

The only book on the market to cover the psychophysics, anatomy, physiology, and clinical deficits of the developing visual system in an accessible format and length. The visual system is the most commonly studied aspect of the nervous system and is the primary model for the study of both normal development and the effects of environment and sensory deprivation on development. This third edition highlights new research and features a large number of illustrations, many in color. It can be ...

Sensory Neuroscience: Four Laws of Psychophysics organizes part of psychophysics -- a science of quantitative relationships between human sensations and the stimuli that evoke them. Although psychophysics belongs to sensory neuroscience, and is coupled to neurophysiology, it has also branched out to various specialized disciplines, including the disciplines of vision and hearing, ophthalmology, optometry, otology, and audiology. Due to this diversification and fragmentation, psychophysics ...

The cerebellum is an intriguing component of the brain. In humans it occupies only 10% of the brain volume, yet has approximately 69 billion neurons; that is 80% of the nerve cells in the brain. The cerebellum first arose in jawed vertebrates such as sharks, and early vertebrates also have an additional cerebellum-like structure in the hindbrain. Shark cerebellum-like structures function as adaptive filters to discriminate 'self' from 'other' in sensory inputs. It is likely that the true c...

Is it impossible to schedule enough time to include users in your design process? Is it difficult to incorporate elaborate user-centered design techniques into your own standard design practices? Do the resources needed seem overwhelming? This handbook introduces Rapid CD, a fast-paced, adaptive form of Contextual Design. Rapid CD is a hands-on guide for anyone who needs practical guidance on how to use the Contextual Design process and adapt it to tactical projects with tight timelines an...

Brain-computer interface (BCI) technology provides a means of communication that allows individuals with severely impaired movement to communicate with assistive devices using the electroencephalogram (EEG) or other brain signals. The practicality of a BCI has been possible due to advances in multi-disciplinary areas of research related to cognitive neuroscience, brain-imaging techniques and human-computer interfaces. However, two major challenges remain in making BCI for assistive robotic...

Advances in the study and understanding of myasthenia gravis have led to the need for the publication of this important new edition. The goal of Myasthenia Gravis and Related Disorders, Second Edition is identical to the first -- to provide the clinician and the scientist with a common resource for understanding this complex disorder. This new edition begins with discussions of neuromuscular junction structure and function and follows with updated chapters covering a wide range of topics, ...

An understanding of the senses - vision, hearing, touch, chemical and other non-human senses - is important not only for many fields of biology but also in applied areas such as human-computer interaction, robotics and computer games. Using information theory as a unifying framework, this is a wide-ranging survey of sensory systems, covering all known senses. The book draws on three unifying principles to examine senses: the Nyquist sampling theorem, Shannon's information theory, and the c...
