Blind Sailors’ Spatial Representation Using an On-Board Force Feedback Arm: Two Case Studies
Similarity representations of participant 3, drawn itineraries relative to the actual itineraries. Arrows show the distances and orientations between the drawn and the actual points . The gridline illustrates spatial distortion. The picture on the left (a) corresponds to representation after navigating in egocentric condition () and the picture on the right (b) to the allocentric equivalent (). These pictures clearly show more important variations between itinerary representations and actual waypoint positions after navigation in the egocentric condition compared to the allocentric condition.
