Blind Sailors’ Spatial Representation Using an On-Board Force Feedback Arm: Two Case Studies

Figure 2

Visualization examples of tracks (clear triangles for waypoints), courses (large dark lines), exploration patterns (thin very dark lines) during voyages, and mental representation of the waypoints layout (clear squares) of participant 1 after navigation. The circles represent the departure points of tracks and courses. Black arrows indicate the wind direction. The picture on the left (a) shows the results in the egocentric condition and on the right (b) in the allocentric condition. No mental representation of the waypoints appears on the left picture because participant 1 was unable to draw it in this condition.
