A Compliant Tactile Display for Teletaction
نویسندگان
چکیده
A teletaction system uses a tactile display to present the user with information about texture, local shape, and/or local compliance. Current tactile displays are at and rigid, and require precise machining and assembly of many parts. This paper describes the fabrication and performance of a one-piece pneumaticallyactuated tactile display molded from silicone rubber. Tactor spacing is 2.5 mm with 1 mm diameter tactor elements. Tactile display compliance ensures contact between the nger and tactile display at all times. Unlike previous pneumatic tactile displays, there is no chamber leakage and no seal friction. A psychophysics experiment showed that a a synthetic grating on the tactile display was perceived as well as a low-passltered real contact.

Human Tactile Spatial Sensitivity for Tactile Feedback
In this paper, we quantify several spatial capabilities of the hmnan tactile system needed for tactile feedback, or teletaction. Psychophysics experiments measure the amplitude resolution of the human tactile system, the effects of shear stress on grating orientation discrimination, and the effects of viscoelasticity {creep and relaxation) on tactile perception for static touch. The results are...

In this paper, we quantify several perceptual capabilities of the human tactile system needed for teletaction. We develop a model of a teletaction system based on predicted subsurface strain. Psychophysics experiments measure the amplitude resolution of the human tactile system, the effects of shear stress on grating orientation discrimination, and the effects of viscoelasticity (creep and rela...
متن کاملSome Basic Issues in Teletaction ∗ R . S . Fearing , G . Moy and E . Tan
Teletaction is the transmission of cutaneous information from a remote tactile sensor to an operator’s skin, typically the finger tips. Ideally, one would like a realistic sensation of directly touching an object with one’s own finger and sense properties such as local shape, hardness, or texture. Teletaction or tactile feedback is one component of haptic feedback, the other component being for...
متن کاملEffects of Shear Stress in Teletaction and Human Perception
Ideally, a tactile stimulator presents information through control of surface normal stress and surface shear stresses. Psy-chophysical experiments measured the eeect of shear stress information on the perception of static stimuli applied normal to the surface. Wax gratings in two diierent orientations and various spatial frequencies were used as stimuli. Elastic layers, representing the anti-a...
متن کاملTactile After-images from Static Contact
It is well known that human skin is a viscoelastic material , and the mechanical and electrophysiological responses to transient indentation have been studied and modelled. For tac-tile display system design, it is also important to determine the perceptual eeects, if any, of skin viscoelasticity. The spatial characteristics and sinusoidal steady state response of the sense of touch have been c...
