In our previous work, we already proposed a new concept of 'universal multimedia access' to narrow the digital divide by providing appropriate multimedia expressions according to users' (mental and physical) abilities, computer facilities, and network environments. In our approach, multimedia contents are played to support some switching functions such as user interface switching, media switching and QoS switching. In our previous work, we have evaluated some types of user interfaces for different age groups and terminal devices. In this paper, we consider the effectiveness of media switching and QoS Control functions.
