With regards to making info technology accessible to individuals with disability, web sites have received much of the attention. In 1998, Congress amended the Rehabilitation Act of 1973, directing federal agencies to create IT resources available to both government workers and the public. A chunk of the work under the alterations entails getting government sites to comply. The W3C released Its Web Content Accessibility Guidelines, a set of recommendations for enhancing the availability of website content. Mobile application development has begun coming to the discussion. Programmers and access specialists now say that the general approaches utilized in the web world may also apply to the fast expanding field of cellular devices and apps.
Mobile OS makers, including Apple, RIM\/BlackBerry and Google, even offer specific indications on developing accessible mobile apps. Forms of Accessibility and way to Integrate Them - Accessibility in application design might take a number of forms. For blind and low vision users, screen readers are included by assistive technology. Screen reader software, like Apples VoiceOver, translates the info appearing on a display to speech. A display, which raises points through holes in a keyboard like apparatus to allow reading can be also driven by A screen reader. Samples of lodging for deaf and hearing impaired consumers include captioning services. And the job of building accessible software doesn't have to be exceptionally time-consuming, notes Doug Brashear, mobile practice manager at NavigationArts, an internet and application design and development consulting company.
Thats especially case when the mobile OS has access features baked in. Surprisingly, the current crop of cellular devices, especially iPhones, a lot more accessibility features built into the OS than youd ever expect, Brashear says. A small amount of additional design and development time, over what's typically required, can yield an extremely usable and accessible app. Apple iOS accessibility attributes, for instance, may get developers 75 percent of the way there, according to Brashear. Crista Earl, manager of web operations in the American Foundation for the Blind, also notes the accessibility features. Among the major capabilities: VoiceOver and Zoom.
VoiceOver, she notes, originated as a screen reader for the Mac platform and later migrated to iOS. Zoom lets users magnify an applications entire screen iOS compared to individual elements, according to Apple. Earl also says that Android, as open source software, enables application makers to develop accessible applications aimed toward niche markets. Accessible App Design Tips - Many access principles for web sites also readily apply to mobile development. Section 508 guidelines, for example, call for text labels to accompany pictures and navigation controls like buttons.
