The diversity of mobile Internet services and devices is
increasing. New services will reach a growing number of
users, which means that user heterogeneity will increase.
Providing device adaptation and personalised services is
a major challenge when moving towards a
The WAP-UAPROF project (November 1999 - October 2001) was
used to design and implement an adaptation proxy with
capabilities for web and media conversion.
Personalisation and communication tools were also
implemented. The service was evaluated with 81 users in
two separate field trials in 2000 and 2001. Profiles of
mobile users were drawn from the results.
Free mobile access to web content brought WAP to a more
personal level. With greater content, users shifted
towards services that answered their personal needs.
There was also a clear need for interactive services,
where users could interact and communicate with other
people. Context-wise, the field trial demonstrated that
much of the use took place at home in the evening, rather
than on the move.
The user studies were complemented with two rounds of
interviews with service providers. The service providers
regarded the conversion proxy as a viable approach to
providing access to web services for mobile customers and
The conversion and adaptation proxy server is a working
solution to give WAP clients access to web services and
to adapt WAP content for different devices. The results
of the user studies stress the fact that mobile devices
are above all personal communication devices. The most
popular services included personal content and services,
which provided users with new ways of communicating with
other people. Targeted services, which coincide with the
users' lifestyles, are needed to serve the interests of a
growing diversity of users.
