This video is a live camera view from a participant walking the maze with the Sensory Substitution Device (SSD). MeloSee SSD converts depth in sound intensity, with stereo modulation for the horizontal axis. Height is converted in pitch (vertical axis). The left view corresponds to depth map with color encoding, from red for the closest (50 cm) to blue for the furthest distance (250 cm). Areas in black are either too far or too close to be detected by the Kinect® sensor and white areas are shade sensor artifacts. Note that black and white are not auditory encoded. The right view corresponds to RGB normal camera-view of the maze. The maze segment displayed here starts between two parallel screens, then turns 90° left after facing a wall.
