This is a collection of tools that are useful in different stages of co-creation projects. Except for the online tools which were developed by us, the tools listed below were developed by td-net of the Swiss Academies of Arts and Sciences and USYS Lab at ETH Zurich. All links below redirect to the td-net tool pages (external website). We plan to add more tools and methods soon. Japanese translations of the tools included below are available on the Japanese page.
