iDTV user interface for elderly users based on simplified navigation scheme

We present a new iDTV user interface based on simplified navigation scheme, which allows very simple and intuitive interaction with complex interactive digital TV features via common TV remote control. The user interface is designed for elderly people and consists of simple views organized in a newly structured navigation map which preserves fast access of basic TV functionality while the advanced features are also easily accessible. Three usability studies (28 participants) showed that our design performs well in a realistic environment. After deployment of our new user interface (more than 100,000 households) the adoption ratio of new interactive digital TV features has risen significantly.
