Abstract
A few years ago, the proliferation of new devices with improved technological characteristics and interfaces, associated with better communication features and services design, conducted to a change in the viewing paradigm. In fact, users started using devices simultaneously. This convergence tendency, which resulted in the use of different devices as part of the same crossmedia system, has created new opportunities to support a multiplicity of contexts of use, as for instance, the ones associated with learning. This paper addresses the effective design of crossmedia systems to generate personalized informal learning contents from iTV, PC and mobile devices with a special focus on mobile devices. It presents the opportunities and challenges of the inclusion of mobile devices on this crossmedia systems, as well as the design challenges that need to be addressed in order to correctly add the mobility feature. The system that was designed to illustrate our research, named eiTV, generates a crossmedia personalized informal learning content, through the form of a web-based content, which provides extra information about users’ selected topics of interest while watching a specific video. The web content may be generated and accessed through iTV, PC and mobile devices and, depending on the users’ needs, viewed immediately or stored for latter view, individually or simultaneously, also from iTV, PC and mobile devices. The system was designed and evaluated based on cognitive and affective aspects that influence the user experience. An evaluation was carried out with high fidelity prototypes with a special focus on mobile devices. The achieved results were very good considering that they helped rethink our mobile related assumptions and they showed that the integration of mobile devices on the system was a success.
