5 Technologies to Promote Community Integration and Participation Through Social Connectedness S ocial connectedness offers another way to promote community integra- tion and participation.

36 FOSTERING INDEPENDENCE, PARTICIPATION, AND HEALTHY AGING accessibility exists, involving technical carryover benefits (that is, Web ac- cessibility also has benefits for individuals without disabilities), long-term financial benefits (due to efficiency of building to Web standards), social responsibilities, legal requirements for accessibility of information technol- ogy, and the growth of the independent living movement and disability rights culture. And people expect mainstream technology to be accessible and to address their needs in the community, with seamless access in health care settings. As with the physical environment, universal design is a key aspect of Web accessibility, said Brewer. As Ron Mace, founder of the Center for Universal Design in Raleigh, North Carolina, has put it, universal design is the design of products and environments to be usable by all people to the greatest extent possible without the need for adaptation or specialized design. Thus, universal design defines the user very broadly. In the context of the Web, universal design implies that everyone matters when it comes to design. Thus, compatibility and interoperability with assistive technology are critical elements of universal design for the Web. Web Accessibility Initiative The World Wide Web Consortium (W3C) is an international ven- dor-neutral organization that develops standards for the Web. Hosted by the Computer Science and Artificial Intelligence Laboratory at MIT, the European Research Consortium for Informatics and Mathematics, and Keio University, W3C encompasses an expanding range of technologies as broadcasting, publishing, entertainment, and games all move increasingly to the Web. One of the four main technical divisions of W3C is the Web Accessibility Initiative, which includes multiple layers of work to support Web accessibility.1 The initiative covers not just hypertext markup lan- guage (HTML) but another 100 or so technical specifications that run on the Web. It identifies accessibility barriers, evaluates resources, conducts education and outreach, coordinates with research, and works to harmo- nize standards. W3C takes a multi-stakeholder approach that encompasses government, academia, industry, and the disability community. It seeks to build consensus through an open and transparent process that is responsive to input from different sources, including the public. As examples of the work done by the Web Accessibility Initiative, Brewer pointed to captioning and signing for people with auditory limita- tions; cognitive and neurological assistance through consistent navigation, appropriate language levels, graphics, and a lack of flickering or strobing that could cause seizures; physical or speech accommodations for people 1 For more information, see http://www.w3.org/WAI.

The initiative has packaged these concepts in a set of accessibility principles, which urge that Web content be • perceivable, • operable, • understandable, and • robust. The Web Accessibility Initiative also has a motivational context so that people understand the need for accessibility and act on that need. It provides training, demonstrations, sample code, and other forms of implementation support for accessibility efforts. It supports accessibility at the technical level across the expanding range of devices. International standards for Web content accessibility have been endorsed by international standards organizations, including the W3C, with provisions for the addi- tion of future technologies. Web developers can customize the standards to the technologies being used in an organization. User accessibility guide- lines cover the entire Web space and pay particular attention to mobile accessibility. The Open Web Platform ties together the current generation of Web technologies, including mobile devices, tablets, traditional desktops, and kiosks. The Web Accessibility Initiative has been working to build acces- sibility into the platform so that it will conform with the goals of universal design. For example, interactive menus and drag and drop capabilities should be accessible to people using assistive technology. Independent user interfaces should add capabilities for touch, gestural, and speech control of Web content. Accessibility should be built in and capable of extension. Concluding Remarks Accessibility solutions largely exist, said Brewer, though continued research is needed to keep up with new advancing technologies. Accessibil- ity policies need to be in place throughout organizations, with end-to-end project management approaches, and training needs to be available where needed. The Web Accessibility Initiative offers resources on getting started, guidelines and techniques, planning and implementing, evaluations of ac- cessibility, presentations and tutorials, and other ways of getting involved with the initiative. Support for future research and standardization efforts in multi-stakeholder forums will continue to promote awareness as well

38 FOSTERING INDEPENDENCE, PARTICIPATION, AND HEALTHY AGING as ensure implementation for newer accessibility solutions as they become available. CLOUD COMPUTING Clayton Lewis, Ph.D. National Institute on Disability and Rehabilitation Research Lewis began by quoting his late mother: “The Internet is a corner I will not turn.” How can an intelligent, capable, older person be convinced to take advantage of the technological opportunities that are available? he asked. Drawing on an example offered by Gregg Vanderheiden at the Univer- sity of Wisconsin–Madison, Lewis showed a picture of a typical computer screen. If described as an image of windows, Lewis’s mother would say, “There are no windows there.” If told to click on a scrollbar, she would say, “What’s a scrollbar?” As an example of a technology suited to his mother, Lewis showed a computer screen developed by Vanderheiden’s group, in which e-mails appear as conventional paper envelopes with printed pages inside. He also showed an animation in which a mail truck comes onto a screen and picks up an e-mail icon so that a computer user knows that an e-mail has been sent. Finally, Lewis showed a photograph of binders containing printouts of some 2,500 messages that his mother had sent and received by e-mail using programs designed to overcome the complexity of electronic communications, developed by CaringFamily LLC. Even people who do not want to turn the Internet corner can take advantage of technol- ogy if provided with answers to their problems, he said. Cloud-Based Accessibility Technology The Global Public Inclusive Infrastructure initiative,2 supported by NIDRR and led by Gregg Vanderheiden, has been working to improve the user experience for computer users with disabilities by allowing those individuals to store their needs and preferences online and then autoper- sonalizing online content and services on the basis of those stored settings. For example, someone could store a need for larger font sizes. Every time that person used a digital device, those preferences would be reflected in the experience. Such a system would help not just people with disabilities but everyone who uses digital devices. NIDRR also sponsors other accessibility initiatives, mostly through 2 For more information on the Global Public Inclusive Infrastructure initiative, see http:// www.gpii.net.

TECHNOLOGIES TO PROMOTE COMMUNITY INTEGRATION 39 partnerships with other federal agencies. For example, NIDRR and the National Institute on Standards and Technology are engaged in a cloud computing project that is assessing cloud-based accessibility technology; the two agencies also have a visualization and usability group that is looking at cloud-based accessibility for inclusive voting. With the U.S. Department of Education, NIDRR is examining cloud-based online educational assess- ment for children with cognitive disabilities and accessibility information in a metadata framework for online educational resources. Opportunities Cloud-based accessibility technology opens a wealth of opportunities, said Lewis. This technology supports not only family communication but community communication. For example, many people move late in life, which often means breaking community ties. Technology can help people maintain ties with church groups or civic organizations even when they are not in the same community. As Lewis pointed out, people are much more likely to maintain their high school friends now than in the past because of applications of technology. Technology can also enhance community par- ticipation, as when social media help people with disabilities interact with their communities or take advantage of educational activities and resources. Technology can help people manage personal data, such as the forms for applying for services and establishing eligibility. People can get assis- tance on demand when needed from trusted parties. For example, someone who sometimes gets disoriented in the community could know that they could always call for help. A major initiative called the National Strategy for Trusted Identities in Cyberspace is developing ways to make online transactions safer, faster, and more private, which could have important implications for people with disabilities.3 Further opportunities for cloud computing include developing improved technology for creating accessible content and services, support- ing the sharing of experience among technology consumers, and using big-data techniques on data from cloud-based services to improve services. For example, a big-data initiative could collect data in different ways that allow for the extraction of structured information and the improvement of services. Concluding Remarks If these opportunities are realized, Lewis concluded, everyone can have access to greatly expanded and improved services. Nevertheless, there is a 3 For more information, see http://www.nist.gov/nstic.

Accessibility technology must be incorporated into the infrastructure that everyone uses, not just provided for people with dis- abilities. Otherwise, services for people with disabilities will continue to be expensive and limited and will constantly lag behind those available to the public at large. Support for work such as the Web Accessibility Initiative of the W3C, and the Global Public Inclusive Infrastructure initiative, he said, is crucial.
