ACM Transactions on Applied Perception (TAP), Volume 2 Issue 2, April 2005

EuroHaptics special issue editorial
Matthias Harders, Marc Ernst
Pages: 69-70
DOI: 10.1145/1060581.1060582

Improving human haptic performance in normal and impaired human populations through unattended activation-based learning
Hubert R. Dinse, Tobias Kalisch, Patrick Ragert, Burkhard Pleger, Peter Schwenkreis, Martin Tegenthoff
Pages: 71-88
DOI: 10.1145/1060581.1060583
Human haptic performance is not fixed, but subject to major alterations through learning processes. We describe a new stimulation protocol that allows to improve haptic performance in humans in a highly systemic way through unattended...

Force constancy and its effect on haptic perception of virtual surfaces
Seungmoon Choi, Laron Walker, Hong Z. Tan, Scott Crittenden, Ron Reifenberger
Pages: 89-105
DOI: 10.1145/1060581.1060584
The force-constancy hypothesis states that the user of a force-feedback device maintains a constant penetration force when stroking virtual surfaces in order to perceive their topography. The hypothesis was developed to address a real-world data...

Waypoint navigation with a vibrotactile waist belt
Jan B. F. Van Erp, Hendrik A. H. C. Van Veen, Chris Jansen, Trevor Dobbins
Pages: 106-117
DOI: 10.1145/1060581.1060585
Presenting waypoint navigation on a visual display is not suited for all situations. The present experiments investigate if it is feasible to present the navigation information on a tactile display. Important design issue of the display is how...

First evaluation of a novel tactile display exerting shear force via lateral displacement
Knut Drewing, Michael Fritschi, Regine Zopf, Marc O. Ernst, Martin Buss
Pages: 118-131
DOI: 10.1145/1060581.1060586
Based on existing knowledge on human tactile movement perception, we constructed a prototype of a novel tactile multipin display that controls lateral pin displacement and, thus produces shear force. Two experiments focus on the question of whether...

Display of virtual braille dots by lateral skin deformation: feasibility study
Vincent Lévesque, Jérôme Pasquero, Vincent Hayward, Maryse Legault
Pages: 132-149
DOI: 10.1145/1060581.1060587
When a progressive wave of localized deformations occurs tangentially on the fingerpad skin, one typically experiences the illusion of a small object sliding on it. This effect was investigated because of its potential application to the display of...

A novel two-dimensional tactile slip display: design, kinematics and perceptual experiments
Robert J. Webster, III, Todd E. Murphy, Lawton N. Verner, Allison M. Okamura
Pages: 150-165
DOI: 10.1145/1060581.1060588
A novel two-degree-of-freedom tactile display reproduces the sensations of sliding contact and incipient slip through the rotation of a ball positioned under the user's fingertip. A pair of motor-driven wheels actuates the ball via contact friction....

HapticWalker---a novel haptic foot device
Henning Schmidt, Stefan Hesse, Rolf Bernhardt, Jörg Krüger
Pages: 166-180
DOI: 10.1145/1060581.1060589
This paper presents a new haptic locomotion interface, which comprises two programmable foot platforms with permanent foot machine contact. It is designed as a scalable and modular system with unit-by-unit extensibility offering up to six plus one...
