Abstract
This research studied the haptic perception of orientations in space rather than in a plane. It aimed at identifying the nature of the system of coordinate used to represent an orientation in space, when two parameters are necessary to code an orientation. Blindfolded participants inserted the tip of the index finger in a thimble mounted at the extremity of a haptic interface, explored the orientation of a "virtual rod" with to-and-fro movements and, after a short delay, reproduced the same orientation with the same fingertip in the absence of the virtual rod. Globally, the haptic reproduction of orientations was anisotropic. When the reproduction of orientations was carried out in the frontal plane, a classical oblique effect (lower performance for the diagonal orientations than for the vertical and horizontal orientations) occurred. When the reproduction of orientations was carried out in space, orientations seemed to be coded in a coordinate system based on the sagittal plane.
