Circumplex expands an existing emotional language into a graphic, tangible and animated system, conceived as a tool for introspection and exchange. Through forms, colours, classifications, manipulable objects and a central animation, the project offers a sensitive way to locate feelings that can be difficult to name. The animation brings the visual language to life and gradually guides the reading of emotions, revealing their nuances, intensities and relationships. By exploring the connection between emotion, language, body and perception, Circumplex opens up possible uses in contexts of mediation, care and therapeutic support.
