analyse descriptive de trajectories perceptives
We wished in this present study, to describe and automate the identification of the strategies implemented by blindfolded subjects. we had resource to the transformation of Fourier in our description. The transform of Fourier is known by his historical relevance in the characterization of the rhythmic behaviour. The trajectories of the subjects are recorded by means of substitution tactile interface. We could define descriptors that differentiate the perceptive strategies. deployed by the subjects. This study has goal to facilitate the acquistion of sensory substitution device. by offering to the subjects rules and strategies which they can adopt. thus they reduce the period of training phase.
