Support for migration through graphical and vocal interfaces in multi-device environments

The increasing availability of new mobile devices in everyday life raises the need for new interaction capabilities to support users immersed in ubiquitous environments. User interface migration provides the possibility of changing device while continuing the task performance and adapting the user interface to the new device. We have designed and developed a solution able to support migration, even among devices with different interaction modalities, in par-ticular graphic and vocal modality.
