drawbacks, we believe that both approaches can
coexist in the same portal: the user selects his
preferred method, according to the characteristics of
the client device and of the connection.
Our future research includes the extension of this
work to the EMMA language, as soon as EMMA-
enabled browsers would be available. We also
intend to provide portal users with other interaction
modalities, e.g., pen input and gesture recognition.
Moreover, we want to include in the portal engine
some tools that can facilitate the multimodal
interaction, e.g., an enhanced user profiling system
and an improved procedure for adapting contents
and interface to mobile devices. Finally, we are
planning to port all our work to the new released
Jetspeed 2 portal. Jetspeed 2 is compliant with JSR
(Java Specification Request) 168, a standard that has
enabled interoperability between portal servers and
portlets (JSR 168, 2003). In this way, most of our
work won’t be hooked on Jetspeed, but it will be
available to all portals that follow the JSR 168
specification.
