Hinweis der Redaktion
- Introduction - who I am, where I work, my interest in accessibility\n2 years ago \nPeople tend to think accessibility = only disabilities\n \n
- Glenda Watson Hyatt and her blog, Do It Myself\nCerebral palsy\nIn exactly 25 words, what does accessibility mean to you?\nNot just people w/ disabilities - everybody\n
- Visual - partial or complete blindness\nCompletely blind and need web sites read to them \nHard of seeing and just need a bit of magnification\nProbably don&#x2019;t use mouse; may use very limited keyboard commands; may use screen reader\nAlso, color blindness (talk about later)\n\n
- Hearing\nCompletely deaf and need alternatives to audio within videos, Flash, Silverlight, etc\n
- Various sources - spinal cord injury; cerebral palsy; muscular dystrophy; multiple sclerosis, Parkinson&#x2019;s\nArthritis\nUsing a mouse may be difficult; keyboard may be easier\nMay prefer voice software\n
- Could relate to memory; problem-solving; attention\nExcessively long text or convoluted terminology\nSkipping around flow of content\nKeep booking or purchasing processes as to the point and simple as possible\nMake error messages meaningful and &#x201C;real&#x201D;\nWhitespace and avoiding things like justified text = easier for dyslexia \n
- As age brackets go up, disabilities increase\nOlder people getting more and more comfortable using the Internet and computers\nAs Scott Meyer said, stores are inconvenient for completely blind; online - shop and it comes to your door\n\nCarol Voss - &#x201C;Disability is the only minority any of us can become a part of&#x201D;\nVideo games...web sites...\n
- ADA = 1990, signed by President Bush\nWhether communicating via print, audio or computer - companies must be prepared to offer information through accessible means\n\nIn 1996, the US Department of Justice made the following statement:\n&#xA0;&#xA0;&#xA0; &#x201C;Covered entities under the ADA are required to provide effective communication, regardless of whether they generally communicate through print media, audio media, or computerized media such as the Internet. Covered entities that use the Internet for communications regarding their programs, goods, or services must be prepared to offer those communications through accessible means as well.&#x201D;\n\n
- Section 508 = amendment to the Workforce Rehabilitation Act of 1973\nRequires Fed Gov&#x2019;mt to ensure that all information, forms, data online are accessible to those w/ disabilities\nCurrently undergoing updating\n
- California legislation\napplies to all businesses\noutlaws discrimination against race, religion, etc....disabilities\n\n
- October 2010 - Update to Communications act signed by President Obama\nPart of it specifies internet-based services must be accessible, unless doing so would result in an undue burden\n\nWhat is undue burden? (can&#x2019;t go out of business to pay for accessibility)\n
- Target - 2006; sued over inaccessibility of web site; missing alt tags; $6 million settlement\nFacebook - under fire for inaccessibility elements, in particular CAPTCHA; agreement w/ AFB\nExpedia - 2009; settled lawsuit over poor representation of disability-friendly hotel rooms\n\nLaw School Admissions Council - sued because online forms weren&#x2019;t accessible\n\n\n
- Software that typically runs over the top of your OS; speaks aloud anything on the active window or app\nJAWS (Freedom Scientific) - most common; 74%; $800-1000\nWindows Eyes (GW Micro) - distant 2nd; $900\nApple VoiceOver - built-in to OS X\nReference Scott Maier at Independence 1st presentation\n
- Those unable to use arms and hands\nAlso for computers\nTypically seen for operating wheelchair\nCan be a straw that is blown into; can be a mouse-operated joystick\n
- Browsers, Mac OS, Windows all have functionality for this\nVery common for those with all degrees of vision limitation\nImportant to limit usage of images to convey text or button text - zooming images pixellates vs. renders bigger\n\n
- Device that connects to a computer\nVery expensive - $2000-5000k\n\n
- Perceivable - one&#x2019;s brain, however they receive the information, is easily able to process it\nOperable - one is able to navigate a site, whether through mouse, keyboard, screen reader, etc\nUnderstandable - one can discipher the content, navigation and flow easily\nRobust - one can utilize a site across a wide range of technology - browsers, settings, etc\n\nFlash - avoid things that flash <2 seconds; time-sensitive controls; \nFlash - good for scalability; keyboard access\n\nJS - time-sensitive; provide means of control\n\nSilverlight - captioning; high-contrast themes\n
- What got Target in trouble\nThose who cannot see, have images turned off because of connection speed, etc\nBe accurate\nBe brief\nDon&#x2019;t repeat what&#x2019;s in the accompanying text\nDon&#x2019;t use terms like &#x201C;Image of&#x201D;\nIf there&#x2019;s already a text caption by the image, no need to repeat it\nUse alt=&#x201D;&#x201D; for design elements like spacers. Otherwise name of image will be read\nIf the image is a link, identify in alt tag where link is taking them\n
- Avoid Read More; Click Here = doesn&#x2019;t say where you&#x2019;re going\nGeneral Rule - Don&#x2019;t Leave the User guessing where link will take them\nObnoxious websites that have images as navigation with zero reference where it&#x2019;s going\nAvoid Making Links only discernible by color\n\n
- Completely Automated Public Turing test to tell Computers and Humans Apart\n
- \n

- \n
- Applies to color of text on color background\nApplies to text overlaid upon images\nWCAG 2.0- level AA requires:\nContrast ratio of 4.5:1 for normal text and 3:1 for large text. \nLevel AAA requires:\nContrast ratio of 7:1 for normal text and 4.5:1 for large text.\nTools online (background color/foreground color) as well Firefox extensions like Colorzilla\n\n
- Captioning (specifying which speaker is speaking)\nTranscripts\n
- Don&#x2019;t assume people know your acronyms;\nEven spelling it out the first time might not be enough;\n<abbr title=&#x201D;As Soon as Possible&#x201D;>ASAP</abbr>\nKeep content clean and simple; don&#x2019;t create synergy, talk offline, ping someone, take on the low-hanging fruit, boil the ocean, deep dive, parking lot it, etc\n
- Accessibility doesn&#x2019;t have to be expensive\nSometimes it&#x2019;s just being careful and considerate\n\n
