Generative techniques, however, lead to confusion,
as in these techniques users are given tools which had been reserved for designers:
collages, diagrams, models. With these tools, users make expressions of their
experience, which can take the form of product proposals or collages, but which serve as
carrier to help them express not concrete solutions (e.g., “a mobile phone with big
buttons”), but deeper-lying motivations, needs, and values (“a need for mobility and
easy access”)
