4. 1 Emotional Flowers
• Creating a Virtual Plant by performing Facial
Expressions (sadness, joy, anger) …
 Individually (Creation)
 In Collaboration with other players
(Co-Creation)
• Multi-Player Online Game for Children (8-14 years
old as main Target Group)
• V4, developed within

27. 3 Active User Involvement
 Co-Design Workshop
 Instant Card Technique
 Idea Generation
for the Co-Creation Part
 Overall Conclusion of Results:
 Children want to cooperate, play
against each other and communicate in a game.
 Children want to know, how good other players are for
comparing themselves with the others.

44. 3 Field Study (Start Event Today!)
• Three-Week Field Evaluation
• Installation in 12 Households
• Children get Experience Package (Feedback Cards,
Camera, Diary, Vidoe Diary ... Interviews, Questionnaire)

45. 4 Conclusions
• Active User Involvement provides valuable input for
shaping the Game Details (e.g. features).
• Iterative User Evaluation as a fix Part of the
Development Process is effective to eliminate problems
in the Game Play.
• Developers and Evaluators should work close together
on solutions for found problems in order to improve the
Game (keep the User’ Needs in mind)
• Working together with Children is very interesting and
challenging, they are very honest in their feedback.
• User Feedback needs to be balanced with the
Development Goals and overall Game Concept.

46. Still, there are a lot of open
issues and questions, which
need to be improved in the
Game Development Process...
we are working on that :)

Optimal Experience!
