This work presents results from an evaluation in the field using a prototype iTV system. Besides standard iTV services (e.g. EPG), this iTV system offers a number of privacy and personalization functions combined with a fingerprint reader in the remote control. The goal was to research how the iTV system would perform in terms of user experience and usability in the field and how users perceive security and personalization functions in the original context of use. Main findings the study showed unexpected perceptions concerning privacy and security issues by users in the field and confirmed good results on usability and user experience gained in prior laboratory studies.
