Adaptive Software and Hardware
Speech Recognition Technology
also called as text reading systemsused to convert text to speech
Refreshable Braille Display
a device which produces Braille letters line by line, according to a corresponding computer monitor text display
Assistive Access to ICT
What is Assistive Access to ICT?
This covers activities like grasping devices, operate machines, and visual aids as well as high tech equipment, like voice-activated computers.
It also refers to electronics-based equipment designed for disabled people.
it allows users to convert spoken words to text
it is useful for people who have difficulty using their hands and therefore must struggle with the mouse and keyboard.
computer can hear and understand the words and executes instructions accordingly which helps deaf people to understand what was spoken, as these words turn out as written text
a program that allows visually impaired individuals to access information on computer monitors bt enhancing the portions being pointed at
a program that can identify and interpret what is displayed on a monitor and then passes it on to the users in the form of text-speech or Braille displays
Head Controlled Pointing Devices
senses the change in position of a small reusable dot planted on the user's forehead
Foot Controlled Pointing Devices
relies on two foot pedals, one to move the cursor and the other to click
*some uses eye movement, ultrasound, infrared, and brain waves to operate computers
Website Accessibility for the Disabled
adaptive software can create a text alternative to the file, which requires less memory and which can be more easily read, particularly if the HTML codes of the website contain an alternative description tag
Non-Downlodable Memory-Demanding Files
Problems with Colors
the browser will try to produce a similar color by dithering, which is an attempt to approximate a color from a mixture of color
websites refined colors by their HTML hexadecimal number, which combines the values of red, green and blue or to specify a safe color, of which users may choose from the 216 different combinations
an accessibility requirements for websites because it is used to navigate to and from different websites on the Web
divides a webpage into two or more independent parts, such as navigation area and information area
The Web Accessibility Initiative (WAI) by W3C:
Web Content Accessibility Guidelines-- A Summary
1. Provide equivalent alternatives to auditory and visual content. Provide content that, when presented to the user, conveys essentially the same function or purpose as auditory or visual content.
2. Don't rely on color alone. Ensure that text and graphics are understandable when viewed without color.
3. Use markup and style sheets and do so properly. Markup documents with the proper structural elements. Control presentation with style sheets rather than with presentation elements with attributes.
4. Clarify natural language usage. Use markup that facilitates pronunciation or interpretation of abbreviated or foreign text.
5. Create tables that transform gracefully. Ensure that tables have necessary markup to be transformed by accessible browsers and other user agents.
6. Ensure that pages featuring new technologies transform gracefully. Ensure that pages are accessible even when newer technologies are not supported or are turned off.
7. Ensure user control of time-sensitive content changes. Ensure that moving, blinking, scrolling, or auto-updating objects or pages may be paused or stopped.
8. Ensure direct accessibility of embedded user interfaces. Ensure that the user interface follows principles of accessible design: device-independent access to functionality, keyboard operability, self-voicing, etc.
9. Design for device-independence. Use features that enable activation of page elements via a variety of input devices.
10. Use interim solution. Use interim accessibility solutions so that assistive technologies and older browsers will operate correctly.
11. Use W3C technologies and guidelines. Use W3C technologies follow accessibilty guidelines. Where it is not possible to use a W3C technology, or doing so results in material that does not transform gracefully, provide an alternative version of the content that is accessible.
12. Provide context and orientation information. Provide context and orientation information to help users understand complex or elements.
13. Provide clear navigation mechanisms. Provide clear and consistent navigation mechanisms-- orientation information, navigation bars, a site map, etc.-- to increase the likelihood that a person will find what they are looking for at a site.
14. Ensure that documents are clear and simple. Ensure that documents are clear and simple so they may be more easily understood.
