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.

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 book explains the mechanisms underpinning the tactile perception of electrovibration and lays the groundwork for delivering realistic haptic feedback on touchscreens via this method. Effective utilization of electrovibration can only be accomplished by simultaneously investigating both the physical and perceptual aspects of the finger-touchscreen interaction. Towards this goal, present work blends the available knowledge on electromechanical properties of the human finger and human tactile perception with the results of new psychophysical experiments and physical measurements. By following such an approach that combines both theoretical and experimental information, the study proposes new methods and insights on generating realistic haptic effects, such as textures and edges on these displays. Besides, state-of-the-art research on the field is reviewed, and future work is discussed. The presented interdisciplinary methods and insights can interest students, broad communities of haptics, neuroscience, engineering, physics, and cognitive sciences, as well as user-interaction experts and product designers from the industry.

"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." --

This report covers some psychophysical experiments on tactile stimulation aimed at determining parameters needed in the design of a tactile display containing about one hundred stimulators. Also covered is the design, construction, and performance of special equipment to control the tactile stimulators by means of programming a small digital computer. Plans for future research are presented. The phenomenon of apparent location was obtained with air-jet stimulation of the skin. A functional relation between pressure difference and apparent location was determined for simultaneous stimulation of two locations on the skin. Also, It has been found that the apparent location phenomenon can be extended to a plane surface by the use of three non-collinear airjets.

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.

The Cambridge Handbook of Applied Perception Research covers core areas of research in perception with an emphasis on its application to real-world environments. Topics include multisensory processing of information, time perception, sustained attention, and signal detection, as well as pedagogical issues surrounding the training of applied perception researchers. In addition to familiar topics, such as perceptual learning, the Handbook focuses on emerging areas of importance, such as human-robot coordination, haptic interfaces, and issues facing societies in the twenty-first century (such as terrorism and threat detection, medical errors, and the broader implications of automation). Organized into sections representing major areas of theoretical and practical importance for the application of perception psychology to human performance and the design and operation of human-technology interdependence, it also addresses the challenges to basic research, including the problem of quantifying information, defining cognitive resources, and theoretical advances in the nature of attention and perceptual processes.
