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 ofhaptics, neuroscience, engineering, physics, and cognitive sciences, as well as user-interaction experts and product designers from the industry.

Includes the first and most comprehensive research on tactile perception by electrovibration to date Explains potential perceptual and physical mechanisms responsible for haptic effects generated on electrovibration displays Proposes new methods to deliver realistic texture feeling by electrovibration and gives insights on prospective future steps for delivering rich, realistic, and controllable haptic sensations on touchscreens
