Designing iTV based crossmedia personalized informal learning contexts

ABSTRACT

Crossmedia systems are becoming increasingly popular. The trends in convergence, integration and co-existence of various media technologies create new opportunities for the generalization of formal and informal learning practices, which are becoming more relevant considering the importance of lifelong learning. Video is a very rich medium to support learning, and TV is a privileged way to access it. By itself, broadcast TV provides limited support to learning processes. But, through structure and interaction, iTV can open the door to flexible environments that can access video and integrate it with different media, accessible from different devices, adequate to support different cognitive modes and learning processes in several learning contexts. In spite of the valuable potential of crossmedia systems to create rich and flexible environments, the design of these systems faces some challenges that may affect their effective use. This paper addresses the effective design of crossmedia personalized informal learning contexts from iTV, through the e-iTV system case study, designed to illustrate and explore this paradigm based on cognitive and affective aspects that influence user experience.
