Rationale 1
• An awareness of different perspectives on
interaction design productions allows:
15
•
Teachers to show students different aspects of a
product or service
•
Creatives to change perspective on their
production and by that think through different
aspects
•
Critics to change perspective on interaction
design productions and by that give insightful
critique
•
Project managers to staff projects and map
competencies
Rationale 2
• Perspectives on quality are assumptions that
act as frames of reference, which can hinder
people from taking advantage of available
opportunities
• Alternative reasoning provides a basis for
reflection, which is a starting point for learning
• Critical reflection can make you stop taking
your assumptions as objective truth

”Behaviour” refers to how a product or service
responds to interaction.
Character and innovation
Does it have a unique and innovatory character and
feel?
Experience of activity
Is the interaction and activity experienced in a
reasonable, alluring and natural way?
Think about several time frames:
- wow-experience the first 10 seconds of the first
impression
- mmm-experience at a closer inspection the first
10 minutes
- ahh-experience the first 10 weeks.
