What will be an ideal response?
The ever-increasing presence of computers in everyone's lives has generated an awareness of the need to address computing requirements for those who have or may develop physical limitations. TheAmericans with Disabilities Act(ADA) requires any company with 15 or more employees to make reasonable attempts to accommodate the needs of physically challenged workers.?Besides voice recognition, which is ideal for blind or visually impaired users, several other input options are available. Users with limited hand mobility who want to use a keyboard can use an on-screen keyboard or a keyboard with larger keys. Users with limited hand movement can use a head-mounted pointer to control the pointer or insertion point. To simulate the functions of a mouse button, a user works with switches that control the pointer. The switch might be a hand pad, a foot pedal, a receptor that detects facial motions, or a pneumatic instrument controlled by puffs of air.?For users with mobility, hearing, or vision disabilities, many different types of output options are available. Hearing-impaired users, for example, can instruct programs to display words instead of sounds. Visually impaired users can change screen settings, such as increasing the size or changing the color of the text to make the words easier to read. Instead of using a monitor, blind users can work with voice output. That is, the computer speaks out loud the information that appears on the screen. Another alternative is a Braille printer, which prints information on paper in Braille.
