TLDR
The proposed technology is based on the electrovibration principle, does not use any moving parts and provides a wide range of tactile feedback sensations to fingers moving across a touch surface, which enables the design of a wide variety of interfaces that allow the user to feel virtual elements through touch.Abstract:
We present a new technology for enhancing touch interfaces with tactile feedback. The proposed technology is based on the electrovibration principle, does not use any moving parts and provides a wide range of tactile feedback sensations to fingers moving across a touch surface. When combined with an interactive display and touch input, it enables the design of a wide variety of interfaces that allow the user to feel virtual elements through touch. We present the principles of operation and an implementation of the technology. We also report the results of three controlled psychophysical experiments and a subjective user evaluation that describe and characterize users' perception of this technology. We conclude with an exploration of the design space of tactile touch screens using two comparable setups, one based on electrovibration and another on mechanical vibrotactile actuation.read more

Physical and Perceptual Independence of Ultrasonic Vibration and Electrovibration for Friction Modulation
Eric Vezzoli,Wael Ben Messaoud,Michel Amberg,Frédéric Giraud,Betty Lemaire-Semail,Marie-Ange Bueno +5 more
TL;DR: This paper will highlight the independence of the two effects on the physical and perceptual point of view to confirm the increased range of sensation and stimulation that can be supplied by the two coupled techniques to the users.

The Application of Tactile, Audible, and Ultrasonic Forces to Human Fingertips Using Broadband Electroadhesion
TL;DR: An electroadhesive approach to controlling friction forces on sliding fingertips is reported which is capable of producing vibrations across an exceedingly broad range of tactile, audible, and ultrasonic frequencies and suggests that an air gap at the skin/surface interface is primarily responsible for the induced electrostatic attraction underlying the electroadhesion effect.

GelTouch: Localized Tactile Feedback Through Thin, Programmable Gel
Viktor Miruchna,Robert Walter,David Lindlbauer,Maren Lehmann,Regine von Klitzing,Jörg Müller +5 more
TL;DR: GelTouch, a gel-based layer that can selectively transition between soft and stiff to provide tactile multi-touch feedback, is presented, showing that the gel is up to 25 times stiffer when activated and that users detect tactile features reliably (94.8%).

A Review of Surface Haptics:Enabling Tactile Effects on Touch Surfaces.
TL;DR: In this paper, the authors review the current technology underlying surface haptics that converts passive touch surfaces to active ones (machine haptic), our perception of tactile stimuli displayed through active touch surfaces, their potential applications (human-machine interaction), and finally the challenges ahead of making them available through commercial systems.

Psychophysics: The Fundamentals
TL;DR: The theory of signal detection has been studied extensively in the literature, see as mentioned in this paper for an overview. But the application of TSD is limited to the measurement of sensory attributes and discrimination scales.
