The
Skeptical Internet User Does Not Search
22 November 2000
Our exploratory user study on the use of
a major portal site in Belgium shows that a category of "skeptical
Internet users" has abandoned searching the web. The
skeptical Internet user has made a return-on-investment evaluation
of his Internet experience, and has come to the conclusion
that the return on some sites is just not worth the investment
of his personal time and energy. What about your site? |

Why
user experience disasters happen at the start of web projects
9 June 2000
Requests for proposals for web project
describe the desired solution but often lack basic information
about the problem that will be solved by the application.
To design a usable user experience you have to understand
the problem first: who are the future users, what are their
current practices and what are their needs? The main barrier
to this understanding is that some corporate cultures lack
the courage to really listen to users. |

The
battle of the disciplines in designing interactive systems
25 April 2000
Multidisciplinary teams designing interactive
systems invest a lot of their time and energy in a battle
between the different disciplines. The starting point to overcome
this battle can be to understand that neither discipline can
win the battle without losing the design war. This article
lists some barriers and potential solutions for multidisciplinary
teams to develop successful interactive systems. |

Emerging
and future usability challenges: designing user experiences
and user communities
2 February 2000
Our hypothesis is that the notion of the
usability of interactive systems depends on the social context
in which interactive systems are used. Our notion of usability
has only partially kept pace with the new usability challenges
that emerge from the changing context of use. Interaction
architects will have to become experts in human-human interaction
in order to tackle the future challenge of designing successful
user communities. |

Trust
and the perception of security
3 January 2000
Trust and security in interactive spaces
do not depend on technical security measures alone. Our limited
research suggests that: "The feeling of security experienced
by a user of an interactive system is determined by the user's
feeling of control of the interactive system." |

Observation
methods and tips for usability testing
12 December 1999
There are two observation methods for usability
testing. "Unobtrusive observation" means you observe what
test users do and refrain from interacting with them. With
unobtrusive observation you learn whether the system is easy
to use. "Obtrusive observation" means you interact with test
users, e.g. by asking questions. With obtrusive observation
you learn more about the usefulness and acceptance of the
system. Besides explaining these observation methods, this
article provides practical observation tips for each method. |

Experiences
of a user's advocate
14 November 1999
External usability consultants are often
asked to solve usability problems with cosmetic changes. But
usability problems can't be solved, they can only be prevented.
In order to be succesful as an internal usability professional,
the development organization needs to adopt a user-centered
perspective. |

Dreaming
about future interaction
12 November 1999
By dreaming about future interactive systems,
we'll be better equipped to adapt new technologies to the
needs of people and businesses. An example, "the future of
personal identification", illustrates the possibilities of
future visions. |
