Perception Problem<\/b><\/p>\n<ul>\n<li>In traditional Collaborative Virtual Environment (CVE) participants are represented as avatars that are continuously updated using 3D tracking technologies<\/li>\n<li>In most systems, collaborative manipulations are very limited and complicated which limits the applicability of CVE for numerous training applications<\/li>\n<li>Manipulating virtual objects with appropriate passive haptic cues could provide an enhanced sense of presence in the virtual world making the simulation feel real<\/li>\n<li>Solving this haptic problem will revolutionize CVE by adding touch perception to any type of training applications<\/li>\n<\/ul>\n<p><b>Proxy Haptic Concept <\/b><\/p>\n<ul>\n<li>One method for adding a sense of touch to virtual objects is to use the concept of proxy haptics, where real physical props are placed around the real environment to match their virtual counterparts<\/li>\n<li>If the physical props are co-registered with the virtual objects a compelling sense of tactile sensation can be achieved, for example, how a mannequin can be used to represent a virtual patient<\/li>\n<li>If the mannequin is co-registered in 3D relative to the virtual user locations, one can be convinced that they are touching a real patient, especially if the tools are tracked in 3D<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><a
