TLDR
A variety of sensory and perceptual consequences of eliminating, via a rigid fingertip sheath, the spatially distributed fingertip force information that is normally available during tactile and haptic sensing are reported.Abstract:
This article reports a variety of sensory and perceptual consequences of eliminating, via a rigid fingertip sheath, the spatially distributed fingertip force information that is normally available during tactile and haptic sensing. Sensory measures included tactile spatial acuity, tactile force, and vibrotactile thresholds. Suprathreshold tasks included perception of roughness, perception of 2-D edge orientation, and detection of a simulated 3-D mass in simulated tissue via fingertip palpation. Of these performance measures, only vibrotactile thresholds and texture perception failed to show substantial impairment. The results are discussed in terms of their implications for the future design of haptic interfaces for teleoperator and virtual environment systems.read more

Haptic perception: a tutorial.
TL;DR: This tutorial focuses on the sense of touch within the context of a fully active human observer and describes an extensive body of research on “what” and “where” channels, the former dealing with haptic perception of objects, surfaces, and their properties, and the latter with perception of spatial layout on the skin and in external space relative to the perceiver.
Tactons: Structured Tactile Messages for Non-Visual Information Display
Stephen Brewster,Lorna M. Brown +1 more
TL;DR: In this paper, the authors describe a new form of tactile output, called tactile icons, which can be used to communicate messages non-visually, and describe the parameters used to construct them and some possible ways to design them.

Tactons: structured tactile messages for non-visual information display
Stephen Brewster,Lorna M. Brown +1 more
TL;DR: A new form of tactile output, Tactons, is described, which are structured, abstract messages that can be used to communicate messages non-visually, particularly where the visual display is overloaded, limited in size or not available.

Project FEELEX: adding haptic surface to graphics
TL;DR: This paper presents work carried out for a project to develop a new interactive technique that combines haptic sensation with computer graphics and a new interface device comprising of a flexible screen, an actuator array and a projector.

Factors influencing the force control during precision grip.
G. Westling,Roland S. Johansson +1 more
TL;DR: It was found that the applied grip force was critically balanced to optimize the motor behaviour so that slipping between the skin and the gripped object did not occur and the grip force did not reach exeedingly high values.

Four channels mediate the mechanical aspects of touch
TL;DR: It is concluded that the four channels work in conjunction at threshold to create an operating range for the perception of vibration that extends from at least 0.4 to greater than 500 Hz and may be determined by the combined inputs from four channels.

Properties of cutaneous mechanoreceptors in the human hand related to touch sensation.

TL;DR: The relationship between the stimulus amplitude and perceived intensity during sustained skin indentations did not match the corresponding stimulus response functions of SA units suggesting non-linear transformations within the central nervous system.

Measuring handedness with questionnaires.
TL;DR: Factor analysis of the individual items revealed a primary handedness factor, and two factors that are idiosyncratic to the wording of the questions, which suggest shortened versions of the two tests are recommended.
