VisitorBox is a structured card-playing activity which is used to generate ideas for new visitor experiences. The tool ensures that a team of people can generate ideas in a way that is informed by real-world opportunities and constraints, and is purposeful rather than aimless. We used VisitorBox in a workshop to generate a set of ideas for visitor experiences that might open up Bromley House to a wider audience. We also used it several times with Theatre Royal to explore how they might expand the usage of the resources at ourtheatreroyal.org through developing new digital experiences.
