Interaction with electronic speech products is becoming a fact of life through telephone answering systems and speech-driven booking systems, and is set to increase in the future. Older adults will be obliged to use more of these electronic products, and because of their special interactional needs due to age-related impairments it is important that such interactions are designed to suit the needs of such users, and in particular, that appropriate mechanisms are put in place to support learning of older users about interaction. Drawing upon the expertise of tutors at Age Concern Oxfordshire, and the results of preliminary investigations with older adults using dialogues in a speech system, this paper explores the conditions which best provide for the learning experience of older adults, and looks at special features which enable instructions and help for learning to be embedded within speech dialogue design.

“…This form of dialogue has been tested against other forms of data input with a standard group of users, i.e., not older adults [3] and described as a pattern called Partitioned Input. It will be interesting to discover whether it is equally successful with older adults.…”

“…The Partitioned Input Messages in effect perform binary chops on the possible entry data [3]. For example when a time for a reminder call is required instead of being asked to enter the time, the user would be asked 'Would you like your reminder call in the morning or afternoon?'…”

Patterns for encapsulating speech interface design solutions for older adults

Proceedings of the 2003 Conference on Universal Usability

An increasing number of older adults will need to use computers and computer related systems in the future to avoid social exclusion and enable them to live more independently in the future. There are therefore currently many interface designers searching for pointers to good design for older adults, a user group which is significantly different from the mainstream younger user groups mainly as a result of age associated impairments. There is currently no detailed body of knowledge from which interface designers can learn how to cater for this user group. This paper suggests a framework for encapsulating good interface design for older adults which is based on rigorous experimental work and sets out the findings in the form of patterns, a representation which has already been used successfully in the domain of software engineering and architecture.A robust framework for interface design is particularly important as those designing systems for older adults tend to be younger people who have no concept of what it is like interact with computerized systems as an older person with the age associated impairments.

“…Thus, where there are 16 possible input values, four partitioned input messages are required (Brownsey et al, 1994). For example, when a time for a reminder call is required instead of being asked to enter the time, the user would be asked 'Would you like your reminder call in the morning or afternoon?'…”

Successful and available: interface design exemplars for older users

Interacting with Computers

2004

An increasing number of older people will need to use computers and computer related systems in the future to avoid social exclusion and enable them to live more independently. For example, we can envisage the web becoming the first source of information on bus timetables or council collections, and even doctor or hospital appointments being handled by a Web applications. There will therefore be many interface designers searching for pointers to good design for older people, a user group which is significantly different from the mainstream user groups as a result of age associated changes. There is currently no detailed body of knowledge from which interface designers can learn how to design for this user group. This paper suggests a framework for encapsulating good interface design for older people that is based on rigorous experimental work and sets out the findings in the form of patterns, a representation previously used in the domain of software engineering and architecture. q
