Input and output devices for physically challenged users

For humans to understand computers and for computers to interact with humans, we have devices to help. These are called input and output devices. Input is any data or instruction that are used by a computer.

Input and output devices for physically challenged users

The system translates data into Grade 1 Braille. Deaf-blind persons who have a Telebrailler or other braille telephone device may use them to read the Braille characters. The telebrailler receives the information like a telephone call and prints it out on its character Braille display.

Annapolis, MD Tel: The data input-output and translation are under computer software control. The Hardware consists of a video tape recorder, an IBM compatible computer, and a special closed caption to braille computer card. The above hardware, when used with the customer supplied TeleBraille, will display closed captioning in either Grade I or II braille.

Nelson system is fully developed and on the market in the U. It is designed for the deaf-blind who already have a Telebraille and the system is connected to the telebraille via a telephone handset.

The software is written in Java, so that it runs on a wide range of computers - from desktops to palmtops. A special wearable computer is being developed, allowing you to use Cupid anywhere with audio or tactile output.

You plug it into the television for visual output. You operate it using a chordal keypad. You can link into the environment using infrared technology, e. You can access the Internet for email and the web.

Universal design principles, Cloudworld has applied principles of universal design, with the aim of making Cupid accessible to all people, regardless of age, ability or disability. Therefore it has been designed with a number of modes of input and output, and to be very simple to use with whatever configuration of input and output the user chooses.

But the system is especially suitable for use with three forms of serial output: There are two pins per finger, and four for the thumb. Pins are spaced about 1 cm. If both pins are vibrated a higher frequency is used, making it easy to distinguish from the case of single pin vibration.

As regards coding, commonly occurring letters involve one finger, and less common letters involve thumb and one finger. Reading at up to words per minute is feasible.

Communication is the basis of human interaction.Secure Digital (SD) is a non-volatile memory card format developed by the SD Card Association (SDA) for use in portable devices.. The standard was introduced in August by joint efforts between SanDisk, Panasonic (Matsushita Electric) and Toshiba as an improvement over MultiMediaCards (MMC), and has become the industry standard.

The three companies formed SD-3C, LLC, a company that.
