Trans-Modal Interface Migration.
This paper presents our solution to supporting runtime migration of Web
application interfaces among devices offering different interaction modalities,
in particular graphic to vocal platform migration and vice versa. Migrating
between platforms implies keeping track of the user interactions in order
to retrieve the runtime state of the interface and maintaining interaction
continuity on the target device. The system can serve user-issued migration
requests containing the identifier of the selected target device, and
can also automatically start the migration procedure when environment
conditions require it. In automatic migration the target platform has
to be automatically selected as well. To this aim, we consider devices
belonging to a restricted environment and have defined selection rules
in order to identify the most suitable available target for the ongoing
