Results of five studies on tactual perception, involving airjet stimulators and a computer-controlled facility, are given. In the first study, alphabetic shapes were presented on an 8x6 airjet array that was translated in a small circle. The increased performance with movement suggests a hypothetical model that qualitatively accounts for the display motion effects. The second study involved pairs of alphabetic shapes presented in rapid succession at the same anatomical location. The interaction effects were: increased letter reversals for short interstimulus intervals; more first-response errors for short-stimulus onset intervals and more second-response errors for long-stimulus intervals; a crossover in first- and second-response error rates of 100 to 200 msec after onset of the first stimulus. In the third study, point airjet stimuli were applied simultaneously to the 24 interjoint regions of the fingers. The results suggest a tactile short-term memory with greater capacity than immediate-memory span but with 0.8-sec decay rate. In the fourth study, visual and tactile stimuli giving equal mean simple reaction times were used. With increased response alternatives, mean visual times increased less than mean tactile times; but with simultaneous presentation of both stimulus types, mean reaction time was much shorter than with either type alone.

This report describes basic studies on tactile perception and communication. In Section II are described experimental sessions in which words, sentences, and paragraphs were transmitted to subjects by a tactile display. Sessions in which a specially designed tactile alphabet was developed are discussed in Section III. Factors such as learnability, edge effects, letter packing, and number of fingers used are considered. Tactually naive subjects were able to identify these letters correctly at a rate of two random letters a second after 25 hours of practice. In Section IV, studies of two-dimensional compensatory tracking with a continuous visual display, a discrete visual display, and a discrete tactile display are described. Finally, in Section VI three series of quantitative studies are reported. The first is a study of the effect of deliberate stimulus pattern 'jitter' on performance. Next, a study concerned with methods of tactually transmitting the magnitude of a single analog parameter is described. Third, the theory of signal detection is applied to a study of the human observer's ability to discriminate among different loci of tactual stimulation.

Designed to make research on touch understandable to those not specifically involved in tactile research, this book provides broad coverage of the field. It includes material on sensory physiology and psychophysics, thermal sensibility, pain, pattern participation, sensory aids, and tactile perception in blind people. While the volume is important for researchers in the area of touch, it should also prove valuable to a broad audience of experimental and educational psychologists, and health professionals. The book should also be of interest to scientists in perception, cognition, and cognitive science, and can be used as a supplementary reader for courses in sensation and perception.

Texture accounts for an important part of the realism of simulated experiences, and it is most certainly true during tactile interaction. We usually experience roughness by running our fingers onto the explored surface. The perception of this fine texture is mediated by the vibrations generated by the encounters of the skin and the asperities of the surfaces. Reproduction of Tactual Textures presents factors that contribute to the mechanics of the interaction between a bare finger and a surface with a view to their artificial reproduction. It discusses the recording and reproduction of tactual textures, and analyses a case study of the development of a device able to record the vibratory signal from a fingertip sliding over a textured surface. The same device is then used in a reverse way to render those previously measured signals to the user’s fingertip. These developments open new questions about the biomechanical properties of the skin and their relation to perception. The second half of Reproduction of Tactual Textures focuses on the implication of the dynamic parameters of the skin onto rendering performance, and it concludes with a study on the important features that are present in the vibratory signal and their relation to texture perception. This state-of-the-art volume highlights the importance of the mechanics and biomechanics during the haptic exploration of surfaces and their possible contribution to perception. Collectively, the findings reported are pertinent to many applications, including robotic perception and the design of effective virtual reality systems.

The return to school following traumatic brain injury (TBI) is fraught with challenges for children and adolescents, their families, and school professionals. This volume provides the practical knowledge needed to understand the neuropsychological problems associated with TBI and facilitate students' reintegration into the regular or special education classroom. Research-based strategies are presented for assessing and accommodating each student's needs, with suggestions for testing that can be completed by practitioners without extensive neuropsychological training. Featuring numerous illustrative clinical examples, the book also includes an extended case history that brings to life the entire process of recovery from TBI. Reviewing basic neuroanatomy, the book first discusses the functional problems and areas of learning difficulty that typically arise from different types of injury. It explores the associated emotional challenges and issues facing families, emphasizing the importance of working closely with parents and building effective home-school partnerships. Identified and briefly described are over 30 psychological measures that can be used to evaluate cognitive and academic skills; memory and learning; attention; executive and reasoning skills; visual-motor and perceptual skills; and psychosocial, emotional, and behavioral functioning. Detailed sample assessments are provided for two students with injuries of varying severity, showing how test results and other information can be integrated into a useful comprehensive report. Guidelines are then presented for managing school reentry and conducting team-based planning and decision making. General programming considerations are discussed, as are specific interventions that incorporate knowledge from the fields of ADHD, learning disabilities, and adult rehabilitation. Written in a clear, non-technical style, this book is an essential resource for school psychologists, counselors, and social workers; special education professionals; and other clinicians working with young people. It will also serve as a text in graduate-level neuropsychological assessment courses.

"This report deals with an attempt to identify and measure individual differences in certain areas of ability dependent upon tactual sensitivity. After extensive preliminary work three areas of ability were defined and seven experimental tests developed. These tests were administered to small groups of subjects and three of the tests were selected for further investigation. A comprehensive analysis was made of the results obtained when the three tests were administered to a sample of fifty military tradesmen. This analysis indicates that a Tactual Test of Spatial Relations developed in the study is capable of reliable measurement* Two tests of tactual acuity are considered to be of limited value as measures of tactual sensitivity." --

Future robots are expected to work closely and interact safely with real-world objects and humans alike. Sense of touch is important in this context, as it helps estimate properties such as shape, texture, hardness, material type and many more; provides action related information, such as slip detection; and helps carrying out actions such as rolling an object between fingers without dropping it. This book presents an in-depth description of the solutions available for gathering tactile data, obtaining aforementioned tactile information from the data and effectively using the same in various robotic tasks. The efforts during last four decades or so have yielded a wide spectrum of tactile sensing technologies and engineered solutions for both intrinsic and extrinsic touch sensors. Nowadays, new materials and structures are being explored for obtaining robotic skin with physical features like bendable, conformable, and stretchable. Such features are important for covering various body parts of robots or 3D surfaces. Nonetheless, there exist many more hardware, software and application related issues that must be considered to make tactile sensing an effective component of future robotic platforms. This book presents an in-depth analysis of various system related issues and presents the trade-offs one may face while developing an effective tactile sensing system. For this purpose, human touch sensing has also been explored. The design hints coming out of the investigations into human sense of touch can be useful in improving the effectiveness of tactile sensory modality in robotics and other machines. Better integration of tactile sensors on a robot’s body is prerequisite for the effective utilization of tactile data. The concept of semiconductor devices based sensors is an interesting one, as it allows compact and fast tactile sensing systems with capabilities such as human-like spatio-temporal resolution. This book presents a comprehensive description of semiconductor devices based tactile sensing. In particular, novel Piezo Oxide Semiconductor Field Effect Transistor (POSFET) based approach for high resolution tactile sensing has been discussed in detail. Finally, the extension of semiconductors devices based sensors concept to large and flexile areas has been discussed for obtaining robotic or electronic skin. With its multidisciplinary scope, this book is suitable for graduate students and researchers coming from diverse areas such robotics (bio-robots, humanoids, rehabilitation etc.), applied materials, humans touch sensing, electronics, microsystems, and instrumentation. To better explain the concepts the text is supported by large number of figures.
