Computers help businesses, schools, and individuals at home to operate more efficiently. This efficiency can take the form of working more quickly, more accurately, or even in ways not previously conceived possible. Computers are impacting our society greatly. Buying groceries at the supermarket and using an automatic banking machine require using computers. The ability to communicate from one computer to another is changing the way people live, study, and work. Today, knowing how to use a personal computer is a basic skill that is becoming part of the literacy picture. In an increasing way, more information is available to us now via computers, so it is important to know how to access it. New applications are being developed every day for using computers. Technology has a new success story in the "computer

Description of Accessibility Guidelines for use of computers by the people with disabilities and elderly Contents I. Purpose II. Coverage III Basic principle IV Specifications

1.Purpose Advances in computerization have promoted the use of computers by individuals for collecting, creating and transmitting information. The computer is thus becoming an essential feature for an individual's daily life. It is therefore very important to make computers accessible to everyone, including disabled and elderly people.

There are currently a number of barriers which people with disabilities and elderly people encounter when they attempt to use computers: (1) Barriers resulting from a disability Difficulties in using input devices with a physical impairment Difficulties in seeing display devices with a visual impairment Difficulties in hearing audio information with a hearing impairment Difficulties in understanding system operation with a learning or cognitive disability (2) Barriers resulting from the weakening of physical and mental capabilities with age (3) Barriers resulting from the temporary loss of mental and physical function due to disease or injury (4) Barriers resulting from operating in a difficult environment, such as a dark or noisy location

II. Coverage In this guideline, the term 'computer' will be taken to include the common forms that computers take, such as word processors, generic personal computers (PCs), workstations, and mainframe computers, along with their retted peripheral devices. Peripheral devices can include standard input devices such as keyboards and pointing devices, and also special input devices such as a Braille keyboard, and standard output devices such as a screen display and printer, as well a special output devices such as a Braille printer

III. Basic principle The principle underlying this guideline is that everyone should be able to enjoy the advantages of using computers without any restriction, including disabled and elderly people. (a) Standardization of adaptive facilities Adaptive facilities are features which can be added to make standard hardware and software usable by people who find it difficult or impossible to us them in their standard form. In order to address the barriers to operating computers as far as possible, adaptive facilities should be standardized and general-purpose computers should all be equipped with them. (b) Promotion of alternative facilities Alternative facilities are features that are provided as an alternative to standard hardware and software, where adaptive facilities are not sufficient. The developers of software and peripheral devices should provide such alternative facilities.

IV. Specifications Facilities to make the standard keyboard usable. Sequential input functions (single key input) When it is necessary to simultaneously press multiple keys, for example, when using the SHIFT, CTRL, or ALT keys with a character key to select a function, it should be possible to accomplish this by setting the system so that the action can be accomplished with the sequential pressing of the individual keys..Configuration of key repeats It should be possible to configure the features of the key repeat function, including turning it on and off, and setting the start period and repeat rate. It should be possible to set the on /off feature for each key separately.

EDUCATIONAL USES of the INTERNET in the WORLD The Internet can be used as a supplement to traditional instructional methods. To complement a lecture, instructors may ask students to find specified Web sites to gain more in-depth knowledge about a particular topic. An instructor may also ask students to search the Internet for information on services offered in a particular location. In preparation for a class topic such as diversity, students may be asked to search the Internet to learn about different ethnic groups or populations at risk.
