Supporting Interactions with Multiple Platforms Through User and Task Models

In this chapter we describe an approach to supporting the interaction design of nomadic applications, which are applications that can be accessed through multiple devices from different locations. This approach is based on the use of task modelling techniques at design time. In addition we use user modelling techniques at run-time to adapt an application to the interaction device, user preferences and user knowledge. With this method it is also possible to adapt the navigation, presentation and content of the user interface to different interaction platforms.
