Resumen
Using a learning system in a mobile environment is not effective if barriers are not overcome in the interaction with targeted users. For that purpose all mobile services, including m-learning ones, demand special attention being paid to interaction with the user. While mobile device applications are becoming more powerful, their development process must utilize the concepts of universal access and universal usability. This paper describes the model of both adaptable and adaptive mobile user interface, through the introduction of a transformable menu component capable to be personalized to each individual user with respect to her/his preferences and interaction style. We discuss the use of customization and adaptation techniques, with the aim to both enhance mobile HCI and to increase user satisfaction, particularly when working with graphically rich m-learning applications.
