Experimental Setup
20 female participants: age group=19-21 years
Random sequence for [modality,rotation] per object to avoid any pattern formationwhere
modality={VV,VH,HV,HH}rotation={UR,X,Y,Z}
Visual mode= 15 secHaptic mode=30sec

The hypothesis that cross-modal recognition is viewpoint independent is validated
The hypothesis that a higher level representation is involved in cross-modal object recognition is still unclear.
