Abstract: | Ubiquitous computing is a challenging area that allows us to further our understanding and techniques of context-aware and
adaptive systems. Among the challenges is the general problem of capturing the larger context in interaction from the perspective
of user modeling and human–computer interaction (HCI). The imperative to address this issue is great considering the emergence
of ubiquitous and mobile computing environments. This paper provides an account of our addressing the specific problem of
supporting functionality as well as the experience design issues related to museum visits through user modeling in combination
with an audio augmented reality and tangible user interface system. This paper details our deployment and evaluation of ec(h)o
– an augmented audio reality system for museums. We explore the possibility of supporting a context-aware adaptive system
by linking environment, interaction objects and users at an abstract semantic level instead of at the content level. From
the user modeling perspective ec(h)o is a knowledge-based recommender system. In this paper we present our findings from user
testing and how our approach works well with an audio and tangible user interface within a ubiquitous computing system. We
conclude by showing where further research is needed. |
