Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Other features and advantages of the present invention will appear more clearly in the following detailed description of preferred embodiments, given by way of non-liming examples with reference to the appended Figures, in which:

(2) FIG. 1 schematically represents a timepiece according to one embodiment of the invention;

(3) FIG. 2 schematically represents a device to be unlocked according to one embodiment of the invention;

(4) FIG. 3 schematically represents the steps of a method according to one embodiment of the invention;

(5) FIGS. 4a to 4d represent the successive positions that the display elements can take during an animation sequence used in the method of FIG. 3.

DETAILED DESCRIPTION

(6) An unlocking method according to one embodiment of the invention will now be described with reference to FIGS. 1 to 4d.

(7) This method uses a timepiece 1. This timepiece may be a watch. Timepiece 1 includes a display device 2. This display device may be a dial. Display device 2 includes display elements 3. These display elements 3 may be: time display hands; digital crystals; a screen; counter hands or crystals; decorative elements that can be animated . . . .

(8) The timepiece also includes actuation means 4 which are actuatable by the user. These actuation means 4 may, for example, include buttons, push buttons, crowns . . . . Timepiece 1 also includes control means 5 configured to animate watch display elements 3 in a predefined animation sequence when they are actuated by actuation means 4.

(9) Thus, by way of example, the timepiece of FIG. 1 includes as actuation means 4 two push buttons P1 and P2. When these two push buttons are pressed in a predefined actuation sequence, for example P1, P2, P2, P1, display elements 3 will be animated in a predefined animation sequence. This predefined animation sequence may, for example, be that represented in FIGS. 4a to 4d: in that case, the watch display elements will successively take the positions represented in FIGS. 4a to 4d, each position being maintained for a predetermined duration.

(10) The predefined animation sequence is preferably factory set, so that each watch has its own animation sequence. However, the animation sequence could also be adjustable by the user, just like the actuation sequence which will allow the animation sequence to start.

(11) This timepiece will be able to be used to unlock a function of a device 6, like that represented in FIG. 2.

(12) The device may, for example be: an electronic device like a smartphone or a computer, a home automation device, for example of the sliding door or roller blind type, a safe . . . .

(13) The method makes it possible, for example, to unlock the device start function, an application stored in the device, the opening or closing of the device, transmission of data to the device . . . .

(14) To achieve this, device 6 includes means 7 for detecting an animation sequence. These detection means 7 preferably include a camera able to film an animation sequence. Device 6 also preferably includes a memory able to store the detected animation sequence. Device 6 also includes comparison means 8 able to compare the detected animation sequence to a reference animation sequence. These comparison means 8 preferably include a processor. Device 6 also includes function unlocking means 9, configured to unlock the function when the detected animation sequence is identical to the reference animation sequence. These unlocking means preferably include a processor.

(15) The reference animation sequence is preferably stored by the user in the device, in an initialisation step. However, it may also be pre-stored in the device during manufacture.

(16) The steps of the method will now be described with reference to FIG. 3.

(17) The timepiece display device 2 is first placed in front of detection means 7 of device 6 in a step 101.

(18) Actuation means 4 are then actuated in a predefined actuation sequence in a step 102. To achieve this, push buttons P1, P2 are pressed in a predetermined combination, for example P1 P2 P2 P1.

(19) Control means 5 then start the predetermined animation sequence in a step 103.

(20) Detection means 7 then detect the animation sequence carried out by the display elements in a step 104.

(21) Comparison means 8 then compare the detected animation sequence to the reference animation sequence in a step 105.

(22) If the detected animation sequence is identical to the reference animation sequence, then the method includes a step 106 of unlocking the function.

(23) If the detected animation sequence is not identical to the reference animation sequence, then the function is not unlocked.

(24) The method thus makes it possible to unlock a function of a device without the user having to remember a complex combination. Further, the method is secure, since even if a third party observes the combination on the watch push buttons or the animation sequence, he or she does not have the watch and therefore cannot copy the observed animation sequence.

(25) Naturally, the invention is not limited to the embodiments described with reference to the Figures and variants could be envisaged without departing from the scope of the invention.
