The perception of size and form of tactile objects relies on visualization, at least for people who are sighted or those who have had longer experience of seeing ( "late blind'", Warren 1994). Non-visual alternative representations are 3D tactile or acoustic representations. This paper describes an auditory display ( Agranovski et all 1996), that provides simultaneous Playback and management by eight independent virtual sound sources (m, n) or by cursors formed by four speakers located in front of the listener as shown in Figure 1.
