WATO is a product-service that improves way-finding in theme parks. This is done through smart and dynamic signage. It consists of a system that analyzes the current flow of people and the way visitors navigate through the park, and uses this information to determine the ideal route for visitors. Once the ideal flows has been determined, the system sends information to the signage in the park. The signage changes depending on the current state of the indicated direction. The signage consists of two parts: foldable arrows with fixed graphics, and a static screen on which different images and information can be displayed.
