Abstract
Many age-associated impairments such as loss of memory and vision make computer use difficult for older adults. This paper is concerned with interface design in a voice Web browser, which compensates for age-associated impairments, particularly loss of memory and vision. It describes a special Voice Help facility talking to older adults through their browser interaction, and reports experiments to establish the mixes of output media (text and speech) that are most effective for information transfer. In particular, the paper demonstrates that older adults’ retention of spoken output is different to that of younger people. The paper provides information on absorption rates for different media for older adults, which supports the design of multimodal systems suited to older adults. This is important for the development of systems that enable older adults to absorb information easily.
