Effect of stereo panning on color identification in Edukoi

Determine whether the stereo spatialisation used in Edukoi’s color-to-sound mapping (red played in the left ear, blue in the right ear, and green in both) improves users’ color identification accuracy, particularly when images contain multiple or composite colors.

Background

Edukoi maps RGB colors to distinctive natural sounds to support memorability and cross-cultural usability and additionally spatialises sounds to aid separation when multiple colors are present (red to the left channel, blue to the right, green centered).

While the authors hypothesize that panning may help disambiguate simultaneous colors, they explicitly note uncertainty about whether this redundancy improved color identification, especially under conditions such as composite colors or suboptimal listening setups.
