Perceived Affordances in Older People with Dementia: Designing Intuitive Product Interfaces

Abstract

The objective of this study was to examine the relationship between intuitive interactions and perceived affordances in product interfaces among older people with dementia. Experiments were conducted by examining the cooking time in the user interfaces of microwave ovens, and the participants involved 25 older people with mild dementia. The results showed that a simple arrangement of bottoms was more desirable for presenting visual information, but the usabilities of these interfaces were undesirable.
