Abstract

The text is scanned optically and read by a microprocessor into a digital memory, with conversion of the optical signals into ASCII code by an OCR computer program. The microprocessor is also in a position to render the ASCII encoded test into acoustic output. The scanned text can be also be reproduced on a screen with any desired deg. of enlargement, and scrolled under the control of the reader. USE/ADVANTAGE - By visually handicapped or reluctant readers, text can be understood more rapidly, accurately and economically than with conventional enlarging TV reprodn. equipment.

Description

Anwendungsgebietfield of use

Die Lesefähigkeit ist an einen Nahvisus von mehr als 0,5 ge­ bunden. Diese Sehschärfe wird von vielen Menschen ohne Hilfs­ mittel nicht erreicht.The reading ability is at a near vision of more than 0.5 ge bound. This visual acuity is used by many people without help medium not reached.

  • a) Sehbehinderte in Blindenschulen, etc.a) Visually impaired in blind schools, etc.
  • b) Ältere Menschen mit Augenleiden.b) Elderly people with eye problems.
  • c) Ab ca. 45 Jahren ist der normalsichtige Mensch ohne Lese­ brille nicht mehr Lesefähig.c) From about 45 years of age, the normal-sighted person is without reading glasses no longer readable.
Stand der TechnikState of the art

Zur Rehabilitation Sehbehinderter werden momentan sogenannte Fernseh- Lesegeräte verwendet, bei denen der Behinderte den zu lesenden Text auf einen Kreuzschlitten unter einer Fernsehkamera bewegen muß, die dann den entsprechend vergrößerten Text auf einem Fern­ sehgerät wiedergibt. Die gleiche Funktion kann mit unserem Ge­ rät schneller, preziser und preisgünstiger erzielt werden. Die akustische Ausgabe ist beim sogenannten Fernsehgerät unmöglich.For the rehabilitation of the visually impaired, so-called television Readers used in which the disabled person reads Move text onto a cross slide under a television camera must then have the appropriately enlarged text on a remote display device. The same function can be done with our Ge advises faster, more precise and cheaper to be achieved. The Acoustic output is impossible with the so-called television set.

Weiterhin sind Lupenbrillen und Fernrohrbrillen im Handel, die aber eine Lesefähigkeit nur bis zu einem Visus 0,1 ermöglichen. Alle vergrößernden Sehhilfen scheitern häufig an der zuweit fort­ geschrittenen Schädigung des Auges.Furthermore, magnifying glasses and telescope glasses are on the market but enable reading ability only up to a visual acuity of 0.1. All magnifying visual aids often fail because of the too far stepped damage to the eye.

Selbst die normale Lesebrille kann von unserem Gerät ersetzt werden, da es sicherlich vielen Lesern angenehmer ist, sich einen Text vorlesen zu lassen anstelle ihn selbst zu lesen.Even the normal reading glasses can be replaced by our device because it is certainly more pleasant for many readers to get one Have the text read out instead of reading it yourself.
