Abstract
A tactile display device that can present tangible relief graphics for visually impaired persons has been developed. The tactile surface consists of a 64/spl times/64 arrangement of tactor-pins with 3 mm interspacing. The tactor-pins are aligned in a hexagonal, rather than a square formation, to assure smooth depiction. The matrix has a total area of 200 mm/spl times/170 mm. Each pin can be raised in 0.1 mm steps to a maximum height of 10 mm. Users can get certain information by touching the pins raised at varying heights with fingers and/or palms. Laboratory assessment of the device with six blind subjects showed its ability to transmit various kinds of information.

Observations on active touch.

TL;DR: Preliminary results indicate that the cross-modal matching of these novel preceptions is possible even for a naive observer, and that practice can bring about errorless judgments in all observers so far tested.

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.
