This paper presents a study to identify the problems and experiences that the elderly have using interactive TV (iTV) services. The study comprised an in-depth qualitative interview series backed up with a questionnaire survey; a list with the elderly's interaction problems and the reasons for wanting or not wanting to use iTV services was developed. These findings in turn lead to the formulation of a set of user requirements. The paper presents the studies carried out and the resulting design recommendations for iTV services for the elderly. The recommendations also take cognitive and as physiological impairments into consideration. The recommendations propose on increased ease-of-use, transparency, colour schemes, familiarity and a reduced set of iTV services for the elderly. Ultimately, designers should aim at customizable interface profiles for future iTV devices and services to better accommodate the diversity of users and especially the elderly.
