METHOD OF CONTROLLING A TOUCH-SURFACE CONTROL DEVICE AND CORRESPONDING CONTROL DEVICE

摘要

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?) of the control trajectory for each sampling period (Te), a parameter representative of the evolution of at least two sampled angles (d?) 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.
