<p>This Patent covers a type slug for guided digital input of symbols in data processing systems. This type slug (1, 1') has recessed (1, 2, 3, 4) or prominent (1', 2', 3', 4') shapes or profiles along which sensors connected to a data processor are located, so that by following the profiles with a finger along a prefixed path, it will be possible to create symbols which the processor can recognize, thus facilitating the utilization of such equipment, particularly by blind and handicapped persons. This type slug (1, 1') also allows for miniaturization of the processor assembly which can thus be built for pocket use or watch type, to take notes or other data to be collected in special and uncomfortable situations.</p> |
