One more step in the communication of deafblind people, the “Dactyls” system

Abstract

DACTYLS is an alternative tactile communication system, in which messages are emitted and received through touch, following the structure of oral language. Its operation is based on the combined use of the tactile fingerprint alphabet and the use of tactile signs and resources, mostly taken from sign language and other newly created ones. Signs adapted for their tactile perception on the palm of the hand, mainly, but also on other parts of the hand, arm and even the shoulder of the deafblind person, and other parts of the hand and, based on some grammatical rules that govern its operation.
