Abstract

The user-centric mentality is usually materialized into the usability engineering techniques. In Human-Computer Interaction (HCI), the generic user-centric approach includes the following activities: 1) user studies and evaluation, 2) user analysis and modelling, 3) prototyping, and 4) implementation. These activities are highly iterative with the exception of user studies and implementation, which are performed less frequently during the product lifecycle. There is an extensive body of previous research in user-centric methods and techniques for personal computers and internet applications, but there is limited research about interactive TV applications. This work investigates the question: 'How does the generic notion of 'user-centric' translate into specific actions for interactive TV (ITV) user interface (UI) design, development and evaluation?'
