Abstract
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 (dθ) 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 (dθ) allocated during an elementary step, repeating the elementary step, and assembling in series the allocated elementary angles (dθ) 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.
