research in the field of human-computer interaction,
intelligent environments and exploiting these
technologies to understand user behavior and user
experience as well as informing the design of
innovative technology and interactive media.
User centered design
An approach that supports the entire development
process with user-centered activities in order to create
applications which are easy to use and have added value to
the intended users
planning real-life evaluation
In this, the emphasis is on designing for the real
world and therefore completing every stage in
human-centered design, starting from eliciting
(latent) user needs to implement innovative
technology and interactive media in a real-life
context of use. In this human centered perspective,
co-creation and the involvement of users in the
design, development, and evaluation of innovative
technologies and interactive media is crucial.
Designing for the real-world
In all stages of human centered design, methods
are required to elicit information from and about
users that are not as such available.
It concerns both methods to obtain information
about needs, desires, capabilities and limitations of
people in an early stage of the design process, and
methods for validating/evaluating the design in later
stages of the co-creation process.

Creative research tools and sensitive
Traditionally, Human-Computer Interaction has been concerned with
designing interactive systems for the workplace, which involved task- and
goal-oriented activities aiming at more efficiency and maximizing utilities.
Current innovative technology and interactive media however are growing
in complexity. For example, it becomes possible to embed computing and
sensing capabilities into a variety of environments, services and
applications resulting in communication possibilities in a much broader set
of contexts. Another dynamic characteristic of these emerging technologies
is that they become more and more personal, they stay and go with one
person a time and are consequently used in various contexts. Having a
human centered perspective implies that such sensitive environments can
monitor people’s behavior and can exchange information about this
behavior. Moreover, it becomes an adaptive environment that meets
dreams, wishes and desires of people, circumventing the need for the user
to provide all information to the system consciously and manually.
In order to cope with these dynamics of real-life
innovation, researchers as well as designers
increasingly find themselves looking beyond
conventional methods to address user needs and
requirements. On the one hand we use and develop
creative research tools to get customer insight; on
the other hand we exploit the capabilities of
‘emerging technologies’ in the development of
innovative measurement techniques and tooling.
Photo-ethnography is just an example of a research
methodology that gives valuable insight in user
behavior. It helps people to express themselves by
using photography, providing deep insight into their
lives, needs, and motivations.

about their attitudes.

currently widespread available and image resolution
has been increased up to 5 megapixels; these
personal devices are therefore most conveniently
situated for capturing (real-time) personal
experiences in a less obtrusive and easy way.

Having state of the art knowledge on methods of
human centered design, students are enticed to
exploit common available tools and techniques
(RFID, Bluetooth, mobile phones, logging) and
develop their own measurement tool and validate it
in real-life context. Results from such in-situ
evaluation are used to polish one’s measurement
techniques and consequently contribute to the
methodological innovation of the Human Centered
