T-PaD: Tactile Pattern Display through Variable Friction Reduction

TLDR
The theory, design and construction of a haptic display for creating texture sensations through variations in surface friction and using finger position and velocity feedback on the display allows for the creation of spatial texture sensations.
Abstract
In this paper we discuss the theory, design and construction of a haptic display for creating texture sensations through variations in surface friction Ultrasonic frequency, low amplitude vibrations between two flat plates have been shown to create a squeeze film of air between the two plate surfaces thereby reducing the friction (Salbu, 1964; Weisendanger, 2001) We show that a reduction of friction will also occur between a human finger and a vibrating plate Thus, a vibrating plate can serve as a haptic interface The amplitude of vibration can also be correlated to the amount of friction reduction between the plate and the finger Varying the surface friction between the finger and the haptic interface is a way of indirectly controlling shear forces on the finger during active exploration Using finger position and velocity feedback on the display allows for the creation of spatial texture sensations

Tactile rendering of 3D features on touch surfaces

TL;DR: A psychophysical model is established that relates the perceived friction force to the controlled voltage applied to the tactile feedback device, and it is demonstrated that participants are three times more likely to prefer gradient force profiles than other commonly used rendering profiles.

A method for controlling tactile sensation of surface roughness using ultrasonic vibration

TL;DR: The proposed method creates a smoother feeling on a surface by applying ultrasonic vibration, with a few micrometers amplitude, to the surface, and enables the generation of resistant impressions, such as 'the surface is rougher/more sticky' and 'a virtual protrusion exists on the surface', when the duration of the ultrasonic vibrations is short enough.

STReSS: A Practical Tactile Display System with One Millimeter Spatial Resolution and 700 Hz Refresh Rate

TL;DR: In this article, a tactile display system is described which can produce "tac-tile movies", that is, rapid sequences of tactile images refreshed at a rate of 700 Hz.

Experimental Evidence of Lateral Skin Strain During Tactile Exploration

TL;DR: An experimental platform for the study of stretch and compression of the human fingerpad skin during tactile exploration is described, motivated by the need to provide meaningful “tactile movies” for a tactile display that uses lateral skin stretch.

The Pantograph Mk-II: a haptic instrument

TL;DR: The redesign and the performance evaluation of a high-performance haptic device system called the Pantograph is described, which is based on a two degree-of-freedom parallel mechanism which was designed for optimized dynamic performance, but which also is well kinematically conditioned.
