Lessons learned in an Austrian Field Trial

How users experience interactive TV (iTV) is determined by various factors; usability is a major one. In industry, usability is often seen as the key element that determines acceptance of new technologies by users. We present some of the results of an MHP-based (Multimedia Home Platform) iTV field trial in Salzburg, Austria concerning usability issues and iTV usage. We give an introduction to the field trial and an overview of its methods to ensure usability of iTV services and to measure their use. We present results from a usability test, give design recommendations, and discuss whether using iTV is an active or a passive user experience
