Towards building pervasive UIs for the intelligent classroom: the PUPIL approach

Information and Communication technologies have the potential to permeate the classroom and modernize the educational process. However, in the context of a smart classroom, building educational applications poses unique challenges from an HCI perspective, due to the diversity of user and context requirements. This paper introduces a framework that facilitates the design, development and deployment of pervasive educational applications that can automatically transform according to the context of use to ensure their usability. The collection of widgets incorporates both common basic widgets (e.g., buttons, images) and mini interfaces frequently used in educational applications, as ready-to-use modules. The designer can either (i) combine and customize widgets from both categories to build an interface just once, or (ii) build and incorporate it as a custom-made mini interface in the collection for future reuse. Finally, the framework's usability has been evaluated with users obtaining very positive results and potential suggestions for extensions.
