Abstract

Despite its rising success, interactive TV (iTV) has found very little attention in the field of HCI. Therefore, the aim of this paper is to investigate the usability of iTV services. It presents the results of a usability test and discusses the implications for further developments. The results show, that prior knowledge of Internet and mobile phones supports the usability of iTV services regarding navigation and text input, while the lack of it leads to great difficulties. Difficult tasks, such as writing a text message, had a success rate of only 20%, while guided tours proofed to be more usable with a success rate of 70%.
