PLEASE NOTE: I created this site to be fully accessible for people with disabilities; please follow this link to change text size, color, or contrast; please follow this link for other accessibility functions for those with visual, mobility, and other disabilities.

I gathered the descriptions and links in this section of the Accessibility & Disability web site to help people find assistive software and hardware for working with computers or printed materials.

Some of this assistive technology includes screen readers, talking web browsers, printed text readers, braille translators (text-to-braille and braille-to-text), screen magnifiers, special computer keyboards, and technology that allows control of a computer through head movements or eye movements.

Apple's Mac, iPhone, iPad, & iPod

"Apple includes assistive technology in its products as standard features — at no additional cost. For example, iPhone, iPad, iPod, and OS X include screen magnification and VoiceOver, a screen-access technology, for the blind and visually impaired. To assist those with cognitive and learning disabilities, every Mac includes an alternative, simplified user interface that rewards exploration and learning. And, for those who find it difficult to use a mouse, every Mac computer includes Mouse Keys, Slow Keys, and Sticky Keys, which adapt the computer to the user's needs and capabilities.... Every new Mac includes an advanced, full-featured screen-access technology that makes it possible for those who are blind or have low vision to control their computer. It's called VoiceOver and it's built into the OS X operating system, so it's preinstalled and ready to use right out of the box. VoiceOver is much more than simply a text-to-speech tool. It uses speech to describe what is happening on your computer, and you can use it to control the computer without seeing the screen.... VoiceOver is the first screen reader to provide true plug-and-play support for braille displays. It includes software drivers for over 40 USB and wireless braille displays, so they start working instantly when you connect them. But that's not all. Through a unique feature called braille mirroring, VoiceOver is the only screen reader that supports more than one braille device at a time — up to 32 braille displays connected simultaneously to the same computer. This enables you to share what you're working on with others who read braille, just as sighted users can share their computer screen using a video projector.... Purple Video Relay Services.... Every Mac comes standard with assistive technologies that help people with disabilities enjoy the power and simplicity of OS X. It includes features like an advanced screen reader, FaceTime, and literacy tools that help those with a wide range of abilities get more from their Mac.... If you are deaf or hard of hearing, you'll find many things to love on a Mac. Communicate easily with friends and family with FaceTime and iMessage, and use captions to watch your favorite content."

Emacspeak Complete Audio Desktop--Bubbles, StarDog, LuckyDog, TweetDog, SocialDog, AbleDog, WorkDog, GoodDog, HappyDog, CleverDog, SmartDog, TopDog, YellowLab, Aster, WonderDog, BlackLab, BlackDog, Illinois, etc.

"Emacspeak provides complete eyes-free access to daily computing tasks. By providing fluent spoken access to local and remote electronic information, the system opens up the wealth of information available on the Internet to visually impaired users.... Emacspeak introduces several improvements and innovations when compared with screenreaders designed to allow blind users to interact with personal computers. Unlike screenreaders that speak the contents of a visual display, Emacspeak speaks the underlying information. As an example, using a calendar application with a screenreader results in the blind user hearing a sequence of meaningless numbers; In contrast, Emacspeak speaks the relevant date in an easy to comprehend manner. The system deploys the innovative technique of audio formatting to increase the band-width of aural communication; changes in voice characteristic and inflection combined with appropriate use of non-speech auditory icons are used throughout the user interface to create the equivalent of spatial layout, fonts, and graphical icons so important in the visual interface. This provides rich contextual feedback and shifts some of the burden of listening from the cognitive to the perceptual domain. Finally, Emacspeak like Linux is completely free; in contrast, commercially available screenreaders typically double the cost of a personal computer. These innovations have together resulted in the system significantly increasing the ability of visually impaired individuals throughout the world to more effectively use information technology for work and leisure."
