Abstract
The purpose of this study was to add to the knowledge of older consumers and their use of electronic products. The work involved redesigning a microwave oven by employing a touch screen interface. This provided a simpler panel with limited choices, step-by-step prompts and larger controls and displays. The design was tested for usability with 8 people over 60 and 8 under 60, in comparison to an existing microwave oven. Participants of all ages completed 4 out of 5 sample tasks faster with the touch screen model. The touch screen model was rated easier to learn and use on all tasks. This paper discusses the redesign of the microwave, the usability test, and final design recommendations.
