Abstract

Elderly people often experience difficulties using interactive TV. This paper presents the findings of a usability evaluation study in combination with eye-tracking conducted for an information oriented interactive TV application. We explored two user groups: elderly users (50 years and above) and users between 20 and 30 years of age. Our focus was on how elderly people perceive and interpret a navigation oriented iTV application. Apart from the standard usability data we used eye-tracking data to gain more insight on why iTV usage seemed to be more difficult for the group of elderly.
