Abstract. As they age, older adult’s present losses in their functional capabilities which cause them can’t continue performing their activities of daily living (ADL) independently at home. We propose Ambient Information Systems (AIS) as appropriate pervasive devices to promote their independent living. Therefore our aim is to determine the utility and usability of AIS to support the independent life of older adults by helping them to perform their activities. In this paper we present preliminary results of a case study that we carried out for understanding the problems and needs that older adults face in doing some of their activities of daily living. In particular, we present results regarding the elderly problems to adhere to their medication prescription. Based on these results we propose AIS to support older adults to medicate. Finally, we present the design attributes incorporated into this AIS, which were identified from the design taxonomies of AIS reported in the literature.
