The invention relates to a method for determining the elementary angle of a control path on a touch surface, characterized in that it comprises measuring two elementary movement values (|dX|, |dY|) along two perpendicular axes (X, Y) for a predetermined duration (dT), comparing said values (|dX|, |dY|) with unitary value ranges of elementary movements (Xu, Yu) of a reference data table and allocating a reference data representative of an angle to an elementary angle (d&#x3b8;) of the control path. The invention also relates to a method for detecting an angular variation of a control path on a touch surface, characterized in that it comprises implementing the above method for determining the elementary angle of a control path on a touch surface and storing the elementary angle (d&#x3b8;) allocated during an elementary step, repeating the elementary step, and assembling in series the allocated elementary angles (d&#x3b8;) in order to determine an angular variation of the control path. The invention further relates to a control module including a touch surface (), characterized in that it comprises a processing unit for implementing the method for detecting an angular variation of a control path as described above.

The invention relates to a method of controlling a touch-surface control device characterized in that it comprises a step of shape recognition of a control trajectory on a touch surface from among at least two predefined shapes of trajectory, in which in the course of a predetermined duration (dT): the control trajectory is sampled in order to determine a sampled angle (d&#x3b8;) of the control trajectory for each sampling period (Te), a parameter representative of the evolution of at least two sampled angles (d&#x3b8;) is compared with a predetermined threshold, and a predefined trajectory shape is assigned to the control trajectory as a function of the result of the comparison. The invention also relates to a control device comprising a tough surface characterized in that it comprises a processing unit for implementing a control method as described above.

The invention relates to a method for controlling a touch surface control device, including at least one step comprising the generation of sensory feedback corresponding to the detection of a pressure applied by a user on the touch surface, said sensory feedback comprising haptic feedback and acoustic feedback. The invention is characterized in that the generation of the acoustic feedback is initiated after the generation of the haptic feedback once a characteristic value of the haptic feedback has exceeded a pre-defined threshold. The invention also relates to an electric control device having a touch surface, characterized in that it includes means for implementing said method ().
