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

UltraHaptics: multi-point mid-air haptic feedback for touch surfaces
TL;DR: This work investigates the desirable properties of an acoustically transparent display and demonstrates that the system is capable of creating multiple localised points of feedback in mid-air, and shows that feedback points with different tactile properties can be identified at smaller separations.

Electrotactile and vibrotactile displays for sensory substitution systems
TL;DR: The authors review the methods used to present visual, auditory, and modified tactile information to the skin and discuss present and potential future applications of sensory substitution, including tactile vision substitution (TVS), tactile auditory substitution, and remote tactile sensing or feedback (teletouch).

Adaptive procedures in psychophysical research.
TL;DR: The general development of adaptive procedures is described, and typically, a threshold value is measured using these methods, and, in some cases, other characteristics of the psychometric function underlying perceptual performance, such as slope, may be developed.

Issues and techniques in touch-sensitive tablet input
TL;DR: In this paper, it is shown that touch-sensitive tablets have some important properties that differentiate them from other input devices (such as mice and joysticks), such as signaling of events, multiple point sensing and the use of templates.
