-
Modified cassette recorder. To record a lecture, own thoughts,
ideas, notes etc.
-
Desktop dictation
system.
To allow audio cassette playback with the aid of a foot
pedal.
-
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 Hardware for Blind
& low vision people of all ages who are visually
impaired and learning disabled to enhance their quality of life
and independence.
