User involvement in industrial contexts
• The aim is cost-efficient product development and commercially successful products – As broad user group as possible – involved users should be
representative – Users may not be motivated to participate if the role of the
product is small in their lives – Users are unaware of implementation constraints and design
practices – Also remote methods needed to reach an international audience
of users – Success may not depend on used methods – users as
information sources and mere direct links are enough

Designing for user experience? • The aim is that using the product feels good
– Stimulation – product is challenging and novel (Hassenzahl, 2004)
– Identification – product communicates the user’s personal values (Hassenzahl, 2004)
– Rewarding (van der Heijden) – Surprise (Derbaix and Vanhamme, 2003)
• Are users able to design pleasurable feelings? – Talking about pleasure is not socially accepted – Users may not be aware of their personal needs, values and
emotions – People have difficulties in remembering emotional experiences
and they easily use generalizations

• User involvement has different approaches suitable to different situations
• Designing for user experience requires new approaches – Users may not be aware of their needs, values and emotions – People rationalize and avoid talking issues that are not socially-
accepted – Designing for experience takes many forms and is challenging,
often easier to start with evaluation
