Ellen BroxNorut, Tromsø, Norway
Norut and me• Norut –multidisciplinary research institute• ICT department – eHealth group• Background in ICT, lately focus on
– Serious Games– Exergames– User centred design
Contents• User centred design• Elderly and games• Exergames• Our experience
Based on GameUp
• Exergames for elderly• Kinect• A stable user group for 3 years
What - User Centred DesignUser-centred design (UCD) is a process in which the needs, wants, and limitations of end users of a product, service or process are given extensive attention at each stage of the design process (wikipedia)
multi-stage problem solving process– analyse and foresee how users are
likely to use a product– test the validity of the assumptions
Why user centred design?• See the product from the users’ perspective• Success depend on them
– Wanting to use it– Use it correctly
• Not easy to imagine the users’ reaction
When?The entire project:
• Requirement• Design• Development• Evaluation
How? Mixed methodsSome common methods• Literature• Focus groups• Usability testing• Questionnaires• Interviews• Participatory design• Field studies
Methods usedRequirements:Commercial gamesLiterature Observations
Design: ObservationsGroup discussionsSemi-structured interviews
Implementation: Iterative trialsObservationsGroup discussions Semi-structured interviews
Evaluations:Structured and semi-structured interviewsquestionnaires
ExergamesVideo games that are also a form of exercise.
Need technology that tracks body movement or reaction.
Exergames and elderly• Elderly
– Little information at the time– Time to think– Their own speed– Light and contrasts– Not noisy
• Elderly still like a challenge and to have fun!

• Buckets lifted• Head on stick man• Moving cloud removed• More blue, less green
