Participatory design of interactive TV user interface for elderly people in Indonesia

The aging process certainly brings impacts on various aspects of elderly people´s life, including social, economic, and health. Basically, elderly people usually spend most of their time staying at home and watching television. The development of interactive television can not be easily accepted by elderly people because of various reasons. This study focuses in designing an interactive television user interface for elderly people in Indonesia. Participatory design was used as an approach in this study. This study involved six elderly people as dedicated participants throughout the design process and who were selected based on several criteria including live independently, familiar with using television, and frequently communicate with their family or relatives. Low-fidelity prototypes (a wizard-of-oz prototype and a mock up prototype) were built based on the selected concept. The prototype evaluation has informed some suggestions to further improve the design since there were users who still experienced difficulties in using the user interface.
