Abstract :
A paradigm is described in which subjects feel virtual objects, created using a two-link robot arm under computer control. Preliminary results show there are systematic distortions in how relative length and relative compliance (preliminary results) are perceived by the subjects, who use only their arm movements in making psychophysical judgments. These distortions depend on the location of the objects in the workspace, and they appear to be related to the dynamical properties of the arm itself
