As the use of digital television (D-TV) has spread across the globe, usability problems on D-TV have become an important issue. However, so far, very little has been done in the usability studies on D-TV. The aim of this study is developing evaluation methods for the user interface (UI) of a personalized electronic program guide (pEPG) of D-TV, and evaluating the UI of a working prototype of pEPG using this method. To do this, first, the structure of the UI system and navigation for a working prototype of pEPG was designed considering the expanded channel. Secondly, the evaluation principles as the usability method for a working prototype of pEPG were developed. Third, lab-based usability testing for a working prototype of pEPG was conducted with these evaluation principles. The usability problems founded by usability testing were reflected to improve the UI of a working prototype of pEPG.
