In this article, we review the current technology underlying surface haptics that converts
passive touch surfaces to active ones (machine haptics), our perception of tactile stimuli …

Friction-induced vibrations are one of the main mechanical signals that, stimulating the
mechanoreceptors, mediate the fine surface texture perception. In this work, isotropic …

This article addresses the problem of producing independent tactile stimuli to multiple
fingers exploring a transparent solid surface without the need to track their positions. To this …

We report an electroadhesive approach to controlling friction forces on sliding fingertips
which is capable of producing vibrations across an exceedingly broad range of tactile …

The topic of this paper concerns the relation between friction perception and finger friction
behaviour. Two experiments were processed for some 20 individuals. The aim of the first …

The world of haptics, tactile rendering of textures and tactile interfaces has witnessed
significant expansion in the last years. When dealing with the design of tactile devices, the …

Moving a slider to set the music volume or control the air conditioning is a familiar task that
requires little attention. However, adjusting a virtual slider on a featureless touchscreen is …

Ultrasonic mid-air haptic feedback enables the tactile exploration of virtual objects in digital
environments. However, an object's shape and texture is perceived multimodally …

Ultrasonic vibrations of a plate can modify the perception of the friction between a surface
and a sliding finger. This principle, coupled with modern position sensing techniques, is able …

In order to mimic Friction-Induced Vibrations (FIV) and render the perception of textures, a
tactile device, named PIEZOTACT, has been developed by a thin, lightweight and flexible …
