Muse is an experimental design project studying the musical perception of the human through three installation experiences which provide different ways to experience music. The first is purely sensational using thermo-active material, and the second display the decoded perception of musical spatiality. The last is a translation between music notation and visual forms. People are encouraged to interact with the installations and explore the music visually with their own perception. The main message is that designers should be aware of how perception affects them in practice.
