How might we design COVID-19 certificates for indoor events?

This video was presented to participants in a participatory design workshop investigating how immunity certificates should be designed to facilitate access to indoor events, using the visit to a theatre as an example. The purpose of creating this video was to facilitate a shared understanding about the phenomenon under investigation to the people who participated in the workshop, as well as to communicate the key concerns and dilemmas and stimulate a discussion and brainstorming of ideas.
