Interactive simplicity for iTV

Abstract

Based on extensive research on users' needs, three simplistic interaction concepts for interactive TV are proposed, developing physical and graphical interface together. This paper describes the development of a user interface by comparing three interface designs, which aim to simplify the interaction and minimize the number of keys on a remote control. With the goal to improve the usability of the interaction concept for various kinds of iTV services, the user interface design concept with a six key remote control has shown to be the best solution in terms of usability and ease of learning, compared to navigation systems using less keys. The concept also shows its advantage in allowing cross-media usage of the navigation concept even on PCs and mobile devices.
