Book Synopsis Tactile Perception by Electrovibration by : Yasemin Vardar
Download or read book Tactile Perception by Electrovibration written by Yasemin Vardar. This book was released on 2020-11-09. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Tactile Haptics by : Roopkanwal Samra
Download or read book Tactile Haptics written by Roopkanwal Samra. This book was released on 2009. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the design of a tactile device that can be used to display varying magnitudes of roughness. The device is designed to be attached to an existing force feedback device in order to create a package that is able to display both macro-level (force feedback) and micro-level (tactile feedback) information to the users. This device allows the users to feel a simulated texture by placing an index finger on an aperture. The stimulus is created with a spiral brush made of nylon bristles. The brush is attached to a DC motor and the speed and direction of rotation of the brush are used to generate textures at the fingertip through the aperture. Three psychophysical experiments are conducted to study the effects of speed and direction on the roughness perception. The first experiment is designed to investigate the sensitivity to a change in the speed of the brush. This experiment is conducted for two levels of base speed and it is found that as the base speed increases, the just noticeable difference (JND) with respect to speed decreases. In the second experiment, it is found that this tactile device is able to represent textures of rough nature, such as sandpaper. It is also found that the human roughness perception cannot be described in a unique manner. Two opposite definitions of rough textures are identified in this experiment. While some users relate an increase in the speed of the brush to increasing roughness, others relate it to decreasing roughness. Further, the results show that the effects of direction are insignificant on the roughness perception for both groups of users. In the third experiment, the effects of direction are studied more closely by presenting the two directions successively with a time gap of $0.5s$. It is found that with this small time gap, the users are able to discriminate between directions, unlike in the previous experiment. The roughness perception is affected by the change in direction when the time gap is small. These findings open further areas that need to be investigated before a robust tactile device can be designed.

Book Synopsis In touch with the future by : Alberto Gallace
Download or read book In touch with the future written by Alberto Gallace. This book was released on 2014-01-30. Available in PDF, EPUB and Kindle. Book excerpt: Out of all the human senses, touch is the one that is most often unappreciated, and undervalued. Yet, the surface of the human body, the skin, is actually one huge sheet of tactile receptors. It provides us with the means to connect with our surroundings. Despite the important role that vision plays in our everyday lives, it is the skin that constitutes both the oldest, and by far the largest of our sense organs. The skin protects our body from the external world and, at the same time, informs us about what occurs on its surface. In Touch With The Future explores the science of touch, bringing together the latest findings from cognitive neuroscience about the processing of tactile information in humans. The book provides a comprehensive overview of scientific knowledge regarding themes such as tactile memory, tactile awareness (consciousness), tactile attention, the role of touch in interpersonal and sexual interactions, and the neurological substrates of touch. It highlights the many ways in which our growing understanding of the world of touch can, and in some cases already are, being applied in the real world in everything from the development of virtual reality (VR) environments, tablet PCs, mobile phones, and even teledildonics - the ultimate frontier in terms of adult entertainment. In addition, the book shows how the cognitive neuroscience approach to the study of touch can be applied to help improve the design of many real-world applications/products as well as to many of our everyday experiences, such as those related to the appreciation of food, marketing, packaging design, the development of enhanced sensory substitution systems, art, and man-machine interfaces. Crucially, the authors makes a convincing argument for the view that one cannot really understand touch, especially not in a real-world context, without placing it in a multisensory context. That is, the senses interact to influence tactile perception in everything - from changing the feel of a surface or product by changing the sound it makes or the fragrance it has. For students and researchers in the brain sciences, this book presents a valuable and fascinating exploration into one of our least understood senses
