The Espacio Acustico Virtual (EAV) is a portable device that acoustically represents visual environmental scenes by rendering objects with the sound of virtual rain drops. Here, an improvement of this device is presented, which adds color to the information conveyed. Two different mappings of color into sound were implemented. Georama is a geometric coding based on Red Green Blue vectors, while Colorama is an associative coding based on the Hue and Saturation model of color space. An experiment was run on both sighted and blind participants in order to assess which of these coding is the most user friendly. The results showed that participants learnt to discriminate colors through sounds better when trained with Georama than with Colorama.

Abstract

The Espacio Acustico Virtual (EAV) is a portable device that acoustically represents visual environmental scenes by rendering objects with the sound of virtual rain drops. Here, an improvement of this device is presented, which adds color to the information conveyed. Two different mappings of color into sound were implemented. Georama is a geometric coding based on Red Green Blue vectors, while Colorama is an associative coding based on the Hue and Saturation model of color space. An experiment was run on both sighted and blind participants in order to assess which of these coding is the most user friendly. The results showed that participants learnt to discriminate colors through sounds better when trained with Georama than with Colorama.
