Automated planning for User Interface Composition

In ubiquitous computing, both the context of use and the users’ needs may change dynamically with users’ mobility and with the availability of interaction resources. In such changing environment, an interactive system must be dynamically composable according to the user need and to the current context of use. This article elicits the degrees of freedom User Interfaces (UI) composition faces to, and investigates automated planning to compose UIs without relying on a predefined task model. The composition process considers a set of ergonomic criterions, the current context of use, and the user need as inputs of a planning problem. The user need is specified by the end-user (e.g., get medical assistance). The system composes a UI in turn by assembling fragments of models along a planning process.
