What is computer access?
These types of AT devices are meant to improve access to computers by facilitating input or enhancing output and provide an alternate means to control the computer. These devices include alternative and adaptive keyboards, expanded keyboards, keyguards, alternative and ergonomic mouse/pointing systems, head-operated pointing devices, Eyeglaze pointing devices, mouth/tongue pointing devices, brain-actuated pointing devices, switches, touch screens, voice input systems, speech-to-text software, voice recognition/voice command software, dictation software, on-screen keyboards, cursor enlargement software, ergonomic computer-based equipment, etc.
Output devices provide alternate access to information available from the monitor or printer. Computer-based output devices generally enable Blind and Vision impaired persons to use or interact with a computer. Includes Braille display/output devices, Braille embosser/printers, screen reading software, screen magnification/enlargement software, large print monitor, etc.
Who is able to benefit from computer access devices?
A computer can provide access to social interaction, shopping, activities, education, employment and information. This category of AT will benefit anyone who has difficulty interacting with a computer because of sensory, physical, or cognitive limitations. Hardware and software products that enable people with disabilities to access, interact with, and use computers include modified or alternate keyboards, switches activated by pressure, touch screens, special software, voice to text software, etc.
Where can I purchase computer access equipment?
Computer access technology can be purchased through electronics and computer stores as well as through companies that specialize in this type of technology, like ATLA. While it may be tempting to select an AT device from a catalog or TV commercial, this is unwise. It is important to find a device with features that match the user’s needs and this can only be done with the help of a professional with sufficient expertise. Following an evaluation with a specialist, it is likely that s/he will recommend one or more devices for trial use before a final recommendation is made.
Can I use computer assistive technology with my home computer or do I need to purchase a special computer?
Computers equipped with Microsoft Windows or Mac OS X operating systems have many access features built into the software. Computers can also be enhanced with specialized hardware and/or software that can accommodate a user’s particular needs. It is, however, suggested that you consult with an AT specialist before purchasing a computer, as assistive technology software, or the combination of software, can prevent the assistive technology from working as expected.
What kinds of needs can be accommodated with computer access technologies?
For those with visual limitations, access can be made possible by hardware- or software-based screen magnification, by screen reading devices that convert visual information on the monitor into speech output, or by devices that convert information into Braille. Those who have difficulty with input using the keyboard and mouse have a vast number of options available to them: enlarged or miniaturized keyboards, reconfigured keyboards, modified mice, trackballs, joysticks, head- or eyegaze-controllers, speech input, or switch-activated scanning arrays. The traditional auditory cues can be replaced with visual cues for those with hearing difficulties. For those with cognitive limitations, computer control functions and the appearance of the display can be simplified.
What are some things I should consider before making an equipment purchase?
- Do I need help inputting information, receiving output, or both?
- What are my strengths, limitations, and preferences?
- What tasks do I want to use my computer for?
- What financial resources can I access?
