Advances in Web-based oriented technologies and services are
taking place with a considerable speed around the world.
Users today facing
principal difficulties with regards to Web-based systems mainly emphasized on
the ineffective and inefficient content provision at “anytime, anywhere and
anyhow” basis. As communications and IT usage become
an integral part of many people's lives and the available products and services
become more varied and sophisticated, users are expected to be able to
personalize a service to meet their individual needs and preferences. Due
to the heterogeneous users’ needs and requirements,
user modeling could be considered as a successful step towards the
identification of users’ preferences. However, could user profiling nowadays be
considered complete enough? Are all the vital parameters of users'
characteristics taken into account in order for the Web-based systems to
provide them with the most user-centric result?
This presentation introduces a comprehensive user model,
incorporating the User Perceptual Preference Characteristics (UPPC) that serves
as the core element
for filtering Web-based raw content, and determines the visual attention,
cognitive and emotional processing parameters that
are different for each user or user group. It further analyzes specific
metrics of these intrinsic users’ perceptual values as well as the
“traditional” user characteristics that together tend to have specific impact
onto the information space and give the most optimized, adapted and personalized result. Based on an
ongoing experimental evaluation with approximately 700 users, both in an
eLearning and eCommerce personalized environment, it has been shown that the
incorporation of human factors in Web-based environments increases users’
performance, accuracy, satisfaction and learning ability while interacting with
the complicated Web structures.
