Touch dominates haptic estimates of discordant visual-haptic size

Touch dominates haptic estimates of discordant visual-haptic size.

Observers (72 college students) estimated the size of plastic squares that they held in their fingers and simultaneously viewed through a reducing lens that halved the squares' visual size. The squares were grasped from below through a cloth that prevented direct sight of the hand. Each estimate was a match selected later, either haptically or visually, from a set of comparison squares. Vision ...

The unity of haptic touch

Haptic touch is an inherently active and exploratory form of perception, involving both coordinated movements and an array of distinct sensory receptors in the skin. For this reason, some have claimed that haptic touch is not a single sense, but rather a multisensory collection of distinct sensory systems. Though this claim is often made, it relies on what I regard as a confused conception of m...

Haptic touch and hand ability

A Study of Touch and Haptic Technologies

This research paper focuses on the human sense of touch and how technology can further explore and embrace this realm. It is intended for students and researchers outside the discipline who seek an introduction to how we recognize touch and the evolving field of haptic technologies. This paper focuses on explaining how the skin functions as an organ and the various ways that we are able to reco...

Toward Haptic Rendering of Full-Hand Touch

Most of the current haptic rendering techniques model either force-interaction through a pen-like tool or vibrationinteraction on the finger tip. Such techniques are not able, nowadays, to provide force-feedback of the interaction through the human hand. In this paper, we address some of the computational challenges in computing haptic feedback forces for hand-based interaction. We describe a h...
