A tactile sensor includes an insulating support including a first face including a first series of parallel conducting tracks and a second face including a second series of parallel conducting tracks, the insulating support being folded and the second face being disposed opposite the first face. The tactile sensor includes an array of conducting tracks extending in an edge zone intended to be folded, along fold lines. The tactile sensor can, for example, be used in a tactile control screen.


A data acquisition method to acquire data from a multicontact matrix tactile sensor having a matrix array of a cells, includes scanning the cells of the matrix array sequentially, and measuring an electrical characteristic of a cell, which represents a weight of the cell. The method also includes comparing the weight with a predetermined significant weight value interval, storing cell data associated with the cell, where the cell data includes the weight and coordinates of the cell in the matrix array, after the weight is determined to lie within the predetermined significant weight value interval. The method also verifies an existence of a data record associated with neighboring cells in a neighboring zone of the cell, and updates the data record associated with the neighboring cells by storing in the data record data associated with the cell, after the existence of the data record is confirmed.


A method of controlling a computerized device with a tactile multi-point matrix sensor placed on a display device, the method including the steps of simultaneously acquiring data of a first contact position and a second contact position of a first and a second finger that is placed on the multi-point tactile matrix sensor, respectively; creating a first cursor and a second cursor that are associated with the first and second finger, respectively; displaying a graphical object on the display device; associating the first cursor and the second cursor with the graphical object to interact with the graphical object; and generating control messages for the computerized device based on positional data of the first cursor, the second cursor, and the graphical object.
