Designing toy prototypes: an exploration of how fidelity affects children’s feedback on prototypes

Testing prototypes with users is essential when developing new products. This qualitative study examines and organizes users’ (children) feedback on physical toy prototypes at various fidelity levels; the data collected comes from a multidisciplinary design studio class tasked with developing wooden toys for the company PlanToys. In this research, we use an organizational framework to categorize stakeholders’ feedback, which includes affirmative feedback, convergent critical feedback, and divergent critical feedback. In our analysis, the children’s feedback was compared by prototype fidelity in terms of both form and function, as well as by the feedback categorization. Findings suggest that form fidelity may bias children toward giving more divergent feedback, that function fidelity may have little impact on feedback given, that children tend to give more types of feedback on lower fidelity than higher fidelity models, and that play value, form, interaction, and function were the highest reported categories of feedback. Based on our observations, we encourage toy designers to be aware of their goals for testing with children before beginning to prototype. This paper is a resource for designers to understand how to prototype for children, as well as resource for researchers studying how specific end users influence the product design process.
