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 the steps of:

• 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, 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).
