Immersion, interaction, and imagination are three features of virtual reality (VR). Existing VR
systems possess fairly realistic visual and auditory feedbacks, and however, are poor with …

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 …

When touched, a glass plate excited with ultrasonic transverse waves feels notably more
slippery than it does at rest. To study this phenomenon, we use frustrated total internal …

The smooth impact drive mechanism (SIDM) is a type of piezoelectric actuator that has been
developed for several decades. As a kind of driving method for the SIDM, the traditional …

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 process by which human fingers gives rise to stable contacts with smooth, hard objects
is surprisingly slow. Using high-resolution imaging, we found that, when pressed against …

Ultrasonic vibration is employed to modify the friction of a finger pad in way that induces
haptic sensations. A combination of intermittent contact and squeeze film levitation has been …

This paper presents the implementation of a novel vibration amplitude control and resonant
frequency tracking for piezoelectric transducers (PTs) and ultrasonic motors (USMs). It is …

Generating tactile data (eg, friction coefficient) from audio and visual modalities can avoid
time-consuming practical measurements and ensure high-fidelity haptic rendering of surface …

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 …
