Method for communication between a portable device comprising a touch-sensitive surface and a peripheral device selected by a directional slide on the touch-sensitive surface

A method for communication between a portable device comprising a touch-sensitive surface and a peripheral device (3k) selected from among at least one peripheral device, comprising:

• a preliminary calibration phase comprising the steps, for each peripheral device (3k), of:
• detecting the said peripheral device (3k);
• acquiring a position (Pk) of the said peripheral device;
• requesting to position the portable device in a calibration position (Tk);
• requesting to carry out a calibration slide with the finger or with the any object, on the touch-sensitive surface of the portable device, in such a way that a direction of the calibration slide (Dk) aims at the said peripheral device;
• acquiring and saving a calibration slide angle (θk) between the reference direction (N) and the direction of the calibration slide, as well as the calibration position;
• determining a current position (T′) of the portable device, and a current orientation of the portable device relative to a reference direction (N);
• determining a direction of a selection slide (D′) on the touch-sensitive surface of the portable device, carried out by an individual's finger or by any object, the direction of the selection slide being relative to the reference direction (N);
• defining, from among the at least one peripheral device, by using the calibration slide angles, the calibration positions, the current position (T′) as well as the direction of the selection slide (D′), the selected peripheral device (3k) whose position (Pk) corresponds to the direction of the selection slide;
• starting a communication between the portable device and the selected peripheral device (3k).
