Social competency training, as part of psychotherapy, for children and
teenagers, requires them to engage on outdoor activities in which they have to
complete tasks such as talking to someone or visiting a specific place.
Currently, the inability for therapists to monitor their patients, to promote
collaborative efforts and to reinforce positive attitudes is a major issue that
affects both the therapy process and its results. In this paper we present an
evaluation experience of a mobile prototype for a geo-referenced collaborative
system that supports in-situ group therapy. The system aims to provide means
for therapists to monitor their patients, their locations and achievements and
includes communication mechanisms that facilitate cooperation between patients
and therapist. We describe the concept behind the project, our initial
low-fidelity prototypes and the experiments that were undertaken to validate
them. Initial results are discussed and future work is defined
