Abstract

A device that communicates pictorial information through tactual stimulation of the skin was used in a study with 16 adults. The device converts an optical TV image into a vibratory display on S's back. The study compared the effects on pattern recognition of two methods of producing stimulus change in the tactual input. Geometric forms and block letters were presented by horizontally panning the TV camera across static figures or by drawing the figures with a moving dot in the camera's field. The drawing procedure produced fewer recognition errors with both types of figures.
