1. A method of providing to a human subject tactile sensation simulating the tactile exploration of an object, comprising the steps of:

  • recording on a suitable support a first sequence of signals corresponding to spatial and temporal parameters, representative of a sequence of tactile exploration of a plurality of points of said object;

    recording on a suitable support a second sequence of signals provided by sensing means operative to sensing, at least one parameter representative of tactile sensation given by each of said plurality of points of said object, said sensing means being operatively moved in contact with said object, so as to reproduce spatially and temporally, the above mentioned sequence of tactile exploration;

    applying simultaneously to a part of the body of said human subject, transducer means respectively operativeto impart movement to said part of the body in response to said recorded first sequence of signalsto exert tactile stimuli to said part of the body in response to said recorded second sequence of signals.
