Activity-Based Choice of Connection and Device in e/m-Learning

In this paper, an e/m-Learning scenario is considered, where users use heterogeneous devices and different network access technologies. Lessons can involve several services, ranging from chat to videoconference, cooperative group work and access to high-quality bandwidth-demanding contents. The problem thus arises of which devices and access technologies can guarantee an appropriate quality of service during the whole lesson. This issue is discussed in two steps. Firstly, some 3D images and High-Definition (HD) streaming video are compared, displayed on different devices through heterogeneous access connections. This test aims at demonstrating that distinct activities can or cannot be performed using whichever device or network technology. Secondly, an early architecture is proposed for scheduling e/m-Learning activities according to the quality needed for the different tasks carried out within a lesson.
