This paper compares and discusses the results from two user studies of interactive television (ITV) with a total of 50 subjects. The interfaces of two different ITV information services were studied: one with a place-like interface rich in graphics, animation and audio, and the other a simple interface with text and still images. In the first study, which evaluated the place-like interface, problems occurred with the mappings of the DTV-remote buttons and with the basic multimedia-interaction techniques used in interface. In the second study it was found that factors of concrete and conceptual nearness, with respect to the TV show, should be taken into account when evaluating the ITV service. (Author)
