Accessibility and Usability of Information Technology by the Elderly

The population of elderly people and the use of computers and the Internet are both growing at extraordinary rates in the United States. The potential exists for elderly people to improve their own lives as well as the lives of others by making more use of this technology. However, the elderly are currently among the lowest users of computers and the Internet. The common belief that older people fear or are indifferent towards technology does not fully explain this low usage. Rather, the elderly are subject to the same income and education divisions that impede accessibility to the population as a whole, as well as certain physical, cognitive, and mental impairments that come with age and can impede usability. Thus, the keys to increasing the numbers of elderly people making effective use of technology are addressing both universal accessibility and universal usability. These solutions are applicable to many other people as well, making their implementation broadly useful and cost-effective.

UUGuide: Practical Design Guidelines for Universal Usability

Even if technology is made more affordable and accessible, it still must be usable by a wide variety of people – experts and novices, abled and disabled – using a wide variety of hardware and software – old and new, text-based and audio/video. Universal usability has thus become another related, but distinct area of research. This web site seeks to identify some of the major issues faced by hardware and software designers who wish to build with universal usability in mind. The Table of Contents to the left contains a list of papers on topics related to universal usability organized into two groups. The first group, User Communities, identifies some of the groups of people who require special considerations when designing hardware and software. The second group, Hardware and Software, looks at the problem from the other direction and identifies hardware and software solutions to usability issues that effect a number of groups. All of the papers were written as resources to provide guidelines for practitioners.

Interface Design for Children’s Searching and Browsing

Elementary-age children are among the largest user groups of computers and the Internet, so it is important to design searching and browsing tools that support them. However, many interfaces for children do not consider their skills and preferences. Children are capable of doing Boolean searches, but have difficulty with the sequential presentation of hierarchical structures used in many category browsers. Based on previous research, we believed a simultaneous presentation of a flat category structure might better support children. We conducted two studies of searching and browsing with these two types of category browsers. Our results suggest that a flat, simultaneous interface provides advantages for both Boolean searching and casual browsing. These results add to the understanding of children’s searching and browsing skills and preferences and suggest guidelines for other interface designers.
