N2 - Is a 2-dimensional (2D) force feedback device capable of presenting 3-dimensional (3D) shapes? The answer is a qualified "yes." "Force shading", a haptic counterpart of bump mapping in computer graphics, presents a non-flat shape on a nominally flat surface by varying the force vector direction in haptic rendering [Morgenbesser and Srinivasan 1996][Robles-De-La-Torre and Hayward 2001]. To our knowledge, such phenomena have been qualitatively measured only by 3D devices, and a quantitative comparison to 2D devices has not been made. We compare thresholds of human shape perception of the plane experimentally, using 2D and 3D force feedback devices.
