Experimental activity base lines
The experimental activity aim
is to verify if the stereo-vision system combined with the haptic device
and its control tecniques is able to give a tridimensional recostruction
of the environment surrounding the user that is explorable in a credible
and coherent way.
According to this idea, each experiment with volunteers is divided in a set of tests; each test analyses the behaviour of the interface in a particular situation and provides us a numerical indication of the whole device performances. The tests point out:
At the moment, the experimental activity involved 22 volunteers. In a few words, we can say that the haptic device provides really good performance in reproducing the main informations a tridimensional scene owns, that is distances among objects and their realative dimensions. We also have about the 50% of succes in the shape recognition tests: this fact underlines the good performances of the system in reproducing the detail of the objects if they are not too little, as the complex scene analisys shown us. Also the real-time performances are really very good.
In the future the experimental activity will be continued, even with the collaboration of really blind volunteers.
