Mobility and low contrast trip hazard avoidance using augmented depth

McCarthy, Chris; Walker, Janine G; Lieby, Paulette; Scott, Adele; Barnes, Nick


OBJECTIVE: We evaluated a novel visual representation for current and near-term prosthetic vision. Augmented depth emphasizes ground obstacles and floor-wall boundaries in a depth-based visual representation. This is achieved by artificially increasing contrast between obstacles and the ground surface via a novel ground plane extraction algorithm specifically designed to preserve low-contrast ground-surface boundaries. APPROACH: The effectiveness of augmented depth was examined in human...[Show more]
