-
Modified cassette recorder. To record a lecture, own
thoughts, ideas, notes etc.
-
-
Scanner.
A device used in conjunction with OCR software.
The printed document is scanned and converted into electronic
text, which can then be displayed on screen as recognizable
text.
-
Standalone reading aids are integrate a scanner, optical
character recognition (OCR) software and speech software
in a single machine, working without a separate PC.
-
Refreshable
Braille display. An electronic tactile
device which is placed under the computer keyboard. A line
of cells, that move up and down to represent a line of text
on the computer screen,enables the user to read the contents
of the computer screen in Braille.
-
Electronic Notetaker.
A portable computer with a Braille or QWERTY keyboard and
synthetic speech. Some models have an integrated Braille
display.
-
Braille
embosser. Embosses Braille output from
a computer by punching dots onto paper. It connects to a
computer in the same way as a text printer.
-
Speech
recognition applications that have emerged
over the last few years include voice dialing (e.g., "Call
home"), call routing (e.g., "I would like to make
a collect call"), appliance control and content-based
spoken audio search (e.g. find a podcast where particular
words were spoken), simple data entry (e.g., entering a
credit card number), preparation of structured documents
(e.g., a radiology report), speech-to-text processing (text
for Open Document word processors, emails...); in the cockpit
of some military fast jets (where it is generally referred
to as Direct Voice Input - DVI -).
-
Voice recognition, or better, speaker recognition is a
related process that attempts to identify the person speaking,
as opposed to what is being said
-
A screen
magnifier, low vision software that interfaces
with a computer's graphical output to present enlarged screen
content. It is a type of assistive technology suitable for
visually impaired people with some functional vision; visually
impaired people with little or no functional vision usually
use a screen reader.
-
Optical
character recognition, usually abbreviated
to OCR, is the mechanical or electronic
translation of images of handwritten, typewritten or printed
text (usually captured by a scanner) into machine-editable
text.
-
OCR is a field of research in pattern
recognition, artificial intelligence and machine vision.
Though academic research in the field continues, the focus
on OCR has shifted to implementation of proven techniques.
Optical character recognition (using optical techniques
such as mirrors and lenses) and digital character recognition
(using scanners and computer algorithms) were originally
considered separate fields. Because very few applications
survive that use true optical techniques, the OCR term has
now been broadened to include digital image processing as
well.
Early systems required training (the provision of known samples
of each character) to read a specific font. "Intelligent"
systems with a high degree of recognition accuracy for most
fonts are now common. Some systems are even capable of reproducing
formatted output that closely approximates the original scanned
page including images, columns and other non-textual components.
ULVA,Seeing With Technology sells state-of-the-art technology
for people of all ages who are visually impaired and learning
disabled to enhance their quality of life and independence.
