Triggering device, comprising at least one symbol representing an action that can be triggered by the triggering device, which comprises: - first detection means for contactless detection: - comprising at least one emitter (105, 205, 305) of at least one wave (110, 210, 310) and at least one receiver (115, 215, 315) of the at least one wave; and - detecting the presence and position of an object (125, 225, 325) as a function of the at least one wave received; and - second detection means (240, 340) for detection by contact, which detect the presence and position of the object (125, 225, 325) as a function of the object pressing on the second detection means, the physical magnitude detected by the second detection means differing by at least one characteristic from the wave received by the first detection means; - a means for determining a speed of motion of the object according to the position of the object supplied by the first detection means; and - triggering means configured to trigger an action represented by a symbol in front of the detection means if: - the first detection means supply a position of the object, and the means for determining a speed of motion of the object determines a speed of motion of the object that is lower than a predefined speed value; or - the first detection means supply a position of the object, and the means for determining a speed of motion of the object determines a speed of motion of the object that is greater than the predefined speed value, and the second detection means detect the user pressing on the device. - first detection means for contactless detection: - comprising at least one emitter (105, 205, 305) of at least one wave (110, 210, 310) and at least one receiver (115, 215, 315) of the at least one wave; and - detecting the presence and position of an object (125, 225, 325) as a function of the at least one wave received; and - comprising at least one emitter (105, 205, 305) of at least one wave (110, 210, 310) and at least one receiver (115, 215, 315) of the at least one wave; and - detecting the presence and position of an object (125, 225, 325) as a function of the at least one wave received; and - second detection means (240, 340) for detection by contact, which detect the presence and position of the object (125, 225, 325) as a function of the object pressing on the second detection means, the physical magnitude detected by the second detection means differing by at least one characteristic from the wave received by the first detection means; - a means for determining a speed of motion of the object according to the position of the object supplied by the first detection means; and - triggering means configured to trigger an action represented by a symbol in front of the detection means if: - the first detection means supply a position of the object, and the means for determining a speed of motion of the object determines a speed of motion of the object that is lower than a predefined speed value; or - the first detection means supply a position of the object, and the means for determining a speed of motion of the object determines a speed of motion of the object that is greater than the predefined speed value, and the second detection means detect the user pressing on the device. - the first detection means supply a position of the object, and the means for determining a speed of motion of the object determines a speed of motion of the object that is lower than a predefined speed value; or - the first detection means supply a position of the object, and the means for determining a speed of motion of the object determines a speed of motion of the object that is greater than the predefined speed value, and the second detection means detect the user pressing on the device.
