Method and device for acquisition of data from a multicontact matrix tactile sensor

A device for acquiring data from a multicontact matrix tactile sensor having a matrix array of a plurality of cells, the device comprising:

• scanning means for scanning the plurality of cells of the matrix array sequentially;
• measuring means for measuring an electrical characteristic of a first cell of the plurality of cells, the electrical characteristic being representative of a weight of the first cell,
• comparing means for comparing the weight with a predetermined significant weight value interval;
• memory means for storing cell data associated with the first cell, the cell data including the weight and coordinates of said first cell in the matrix array, after said comparing means has determined that the weight of the first cell lies within the predetermined significant weight value interval;
• verification means for verifying an existence of a data record in the memory means associated with neighboring cells located in a neighboring zone of said first cell;
• and
• updating means for updating the data record associated with the neighboring cells of said first cell by storing the cell data associated with said first cell, and which includes the weight of the first cell, in the data record associated with the neighboring cells, after said verification means has determined the existence of the data record associated with the neighboring cells.
