Prototyping is a common method in the Nordic user involving design approach. However little is empirical shown about how priming factors affects the out-put of prototyping sessions. In this paper we investigate whether three parameters; material, challenge formulation and warm-up sessions; affect the out-put of the session in form of the generated prototypes.
The research questions for this study has hence been: How does the material, challenge formulation and warm-up phases affect the out put of a prototype session? We led ten participants through three rounds of individual prototyping-sessions each lasting ten minutes. The participant was given one of three challenges to solve in each round and was allowed to prototype in one out of four materials (paper, card board, foam or Lego) in each round. After each round the participants presented the prototypes to a running camera. On average each participant made approximately 3.7 prototypes in each round, which lead to 112 prototypes in total. These prototypes were evaluated and measured regarding number of parts, number of functions, number functions mentioned in the presentation, size and 2D versus 3D. After each session the participant were asked to fill out a questionnaire concerning their experience with the different materials and challenges.
Through statistical ANOVA test analysis of the mentioned data we were able to conclude that material, challenge formulation and warm-up significantly affected the prototypes in terms of number of parts, size, number of functions and level of abstractness (p
