    [0001] -1- "Method for interacting with an electronic and / or computer apparatus implementing a capacitive control surface and a peripheral surface, interface and apparatus implementing this method" Technical Field The present invention relates to a method for interacting with a device electronic and / or computer implementing a capacitive control surface and a peripheral surface. It also relates to a human-machine interface and a user device implementing this method. The field of the invention is, but not limited to, that of the human-machine interfaces (HMI) for interacting with a user device, implementing a capacitive detection technology. More particularly, the field of the invention is that of HMIs comprising a control surface with capacitive technology, to interact with a user device without contact with said control surface. State of the Prior Art Most electronic communication devices or audiovisual devices are equipped with screens or control surfaces, commonly called touch surfaces, to interact with these devices. In devices such as tablet or smartphone, the control surface is transparent. It is integrated in or on the display screen of these devices to increase the size of the display screen.
    [0002] These control surfaces are mostly based on capacitive measurement techniques. Depending on the techniques used, they make it possible to detect control objects, such as fingers or a stylet, in contact with the control surface or sometimes at a distance from this surface.
    [0003] Capacitive measurement techniques based on mutual capacitance measurements are known. In these techniques, mutual coupling capacitances are measured between emitting electrodes and receiving electrodes. When a control object is approached near an interaction zone between the transmitting and receiving electrodes, it disturbs the field lines and modifies the measured mutual capacitance. This type of method is essentially limited to contact measurements because of its limited sensitivity. The emitter and receiver electrodes are often arranged in rows and columns with overlapping areas. Capacitive measurement techniques based on individual capacitance measurements (generally called self mode) are also known. In these techniques, the capacitance between each electrode and one or more control objects in the vicinity is measured. These methods make it possible to detect objects away from the electrodes, without contact, therefore. The electrodes may be arranged for example in rows or columns, or in a matrix arrangement. However, when the row and column structure is used, the presence of multiple objects simultaneously generates "ghosts" that lead to false detections. In this case the method is therefore essentially limited to detecting only one object at a time. For example, document WO 2011/015794 describes a method and a control interface device based on a "self" type measurement technique with electrodes in matrix form which makes it possible to detect objects in contact and at a distance. electrodes with high sensitivity through the use of a guard and an electronics referenced to the potential of this guard. Small smartphone-type portable terminals (for example) pose particular constraints of use and ergonomics. In their design, it is generally attempted to maximize the size of the control surface with the display in relation to the size of the face of the apparatus on which it is located, in particular by ensuring that it extends almost to the edges, near the edge, of the apparatus. In this case, when the apparatus is held by hand, the fingers which are placed on the edges or edges extend to the immediate vicinity of the control surface. Apparatuses having such a capacitive control surface generally comprise on their edge, or more generally on the periphery of the control surface, additional selection means for selecting certain functions such as the volume control. turning on or off the display screen, etc. These selection means may comprise for example electromechanical buttons, or sometimes additional capacitive sensors. These elements, however, increase the complexity and cost of manufacturing the apparatus. With certain capacitive measurement techniques implemented for the control surface, in particular in "self" mode, the measurement electrodes of the periphery of the control surface have a sensitivity that makes it possible to detect fingers present on the edge of the control surface. apparatus in proximity. This phenomenon is known as "edge effects". For example, document WO 2013/160323 discloses a method for interacting with apparatus which exploits this sensitivity to the edge effects of the measurement electrodes of the periphery of the control surface. This document notably describes commands that can be made from actions in a peripheral zone around the control surface, in particular with the fingers holding the apparatus. This method has the advantage of eliminating electromechanical control buttons. It also has the advantage of allowing the realization of commands 20 with actions that are not executed at a precise position on the device (in contrast with actions on a materialized button), which makes it possible to adapt to the morphology of the user's hand. Indeed, since the whole of the peripheral zone is sensitive, an action (for example a "tap") can be detected and exploited at any position of this peripheral zone. The use of the peripheral zones around the control surface thus opens up new possibilities for commands or interactions. It also poses problems of robustness and reliability of command interpretation, with an increased risk of misinterpretation of parasitic gestures. The object of the present invention is to propose new methods of interaction with the peripheral zones. Another object of the present invention is to provide such interaction methods which have increased reliability and robustness. SUMMARY OF THE INVENTION This object is achieved with a method for interacting with an electronic and / or computer apparatus comprising: a control surface; At least one so-called peripheral surface arranged on the periphery of said control surface; a plurality of capacitive electrodes arranged at least along the control surface and arranged to detect control objects in a vicinity of said control surface and said at least one peripheral surface; which method is characterized in that it comprises steps of: - detecting a sequence of actions comprising a plurality of elementary actions performed at least partially sequentially, by at least one control object, at least in part at the contacting or facing said at least one peripheral surface; triggering, according to said sequence of actions, at least one function in said apparatus. Thus, according to the method of the invention, a function or a control of the apparatus is triggered by a sequence of actions, that is to say a temporal sequence of elementary actions carried out, for a part of at least in the peripheral areas opposite peripheral surfaces. "Elementary actions" can include any type of action performed by one or a plurality of control objects such as a finger. These elementary actions may include actions generally known and used to interact with a control surface. They can include the actions known as: "tap", double "tap", long press, "swipe", "flick" (sweep and detach), move, "slide" ( slip), scroll (scroll) and actions performed remotely, 30 in "hovering" (hovering) .... It should be noted that a double "tap" can be considered in the context of the invention as a single elementary action because it is a single action defined in this form. The elementary actions may also include actions that take into account a detection or measurement of the pressing pressure exerted by one or more control objects on a surface of the device. These elementary actions may include in particular "tap" or long supports carried out with a pressing force, or by applying a pressure variable in time. These measurements or these detections of bearing pressure can be carried out by any means, including: a measurement of the deformation of the control object or objects on a surface, from an analysis of the measurements obtained with the capacitive electrodes; a displacement or measurement of deformation of the bearing surface, from measurements obtained with the capacitive electrodes and possibly additional sensors (deformation of a dielectric layer which influences the capacitive measurement, measurement of the overall displacement of the surface support, ...). The peripheral surface or surfaces may extend for example on the face of the device that supports the control surface. They may also extend to the adjacent faces which constitute the sides of the apparatus (ie faces which have an orientation substantially 90 degrees to the face of the control surface). Thus, the method according to the invention makes it possible to produce commands that are sufficiently complex to limit the risks of tripping of accidental commands.
    [0004] It thus makes it possible to robustly implement commands that can be triggered in different positions (or independently of the position) in the peripheral zones so as to adapt to the morphology of the user or the way he has took the device (right hand, left hand, small or large hand, ...).
    [0005] The function or command may use input parameters from the elementary actions (or at least the last elementary action) of the sequence that triggered it. The triggering of a function can comprise the stopping of another function, possibly previously triggered by a sequence of identical or different actions. It also makes it possible to implement codings, that is to say sequences that are sufficiently complex to be difficult to reproduce by an unauthorized user. Such encodings may for example be used instead of the input on the control interface of a PIN code, or the drawing on this control interface of a pattern to unlock the device. They also have the advantage of allowing quick execution with the hand holding the device. According to embodiments, the method of the invention may comprise a control object detection step in contact with or facing a peripheral surface by exploiting the edge effect of at least one capacitive electrode. said control surface being in proximity to said peripheral surface. According to embodiments, the method of the invention may also comprise a control object detection step in contact with or facing a peripheral surface by means of capacitive electrodes present on this peripheral surface.
    [0006] According to embodiments, the method of the invention may comprise a step of detecting an elementary action corresponding to at least one of the following actions: a contact of a control object with a peripheral surface ; contact for a duration less than a predetermined duration of a control object with a peripheral surface (for example a "tap"); a contact for a duration greater than a predetermined duration of a control object with a peripheral surface (for example a long press); - a displacement of a control object on a peripheral surface (such as for example a "slide" or a "scroll"); moving in a predetermined range of distances from a control object to a peripheral surface. According to embodiments, the method of the invention may comprise a step of detecting an elementary action performed in contact with or facing the control surface. Thus, the sequence of actions may also include actions performed on or opposite the control surface. The method of the invention may in particular comprise a step of detecting an elementary action corresponding to at least one of the following actions: a contact of a control object with the control surface (for example a "tap" ", A long press, ...); a displacement of a control object on the control surface (for example a "swipe" or a "scroll", ...); - An overflight of a control object opposite the control surface (for example following a predetermined path or gesture).
    [0007] According to embodiments, the method of the invention may comprise a step of detecting an action sequence comprising a first elementary action and a second elementary action performed simultaneously. These simultaneous elementary actions may be performed for example by two fingers on two opposite sides of the apparatus (eg thumb and forefinger). According to embodiments, the method of the invention may comprise a step of detecting a sequence of actions satisfying at least one of the following conditions: a sequence comprising a first elementary action and a second elementary action carried out sequentially; a sequence comprising a first elementary action and a second elementary action performed sequentially in a time interval of less than a predetermined duration; Sequence comprising a first elementary action and a second elementary action performed sequentially and separated by a time interval less than a predetermined duration. - Sequence comprising a first elementary action and a second elementary action performed sequentially and separated by a time interval greater than a predetermined duration. More generally, the detection of the action sequence may include taking into account a temporal parameter connecting two consecutive elementary actions. Sequential and simultaneous characters can of course be combined. For example, an action sequence may comprise a long held hold (corresponding to a static position), then a "tap" or "slide" while this long press is held. According to embodiments, the method of the invention may comprise a step of detecting an action sequence comprising a first elementary action performed in a first zone of the peripheral surface and a second elementary action carried out in a second zone. 15 area of the peripheral area. These first and second zones of the peripheral surface can be defined anyway. They may comprise, for example: at least one fixed zone precisely located on the peripheral surface (similar in its extent for example to a physical switch); at least one extended fixed zone, corresponding to part or all of one side of the apparatus (for example right or left relative to the orientation of the display); a second zone whose position is defined relative to the position of the first zone (for example above, below, on an opposite side of the apparatus relative to the orientation of the display). According to embodiments, the method of the invention may comprise a step of detecting an action sequence comprising: at least two elementary actions performed sequentially; At least three elementary actions performed sequentially; at least four elementary actions performed sequentially; a number of elementary actions sufficient to allow an unambiguous detection of this sequence of actions. In general terms, an action sequence according to the invention may be defined by a set of parameters that may comprise elements among: elementary actions, a succession of elementary actions, temporal parameters ( duration, frequency, time interval) relating to these elementary actions and / or their succession; - Location parameters of the elementary actions in the peripheral zones and possibly on the control surface.
    [0008] According to embodiments, the method of the invention may comprise a step of triggering a function corresponding to an unlocking of the apparatus. The sequence of actions can then be, for example, of average complexity to provide security against accidental unlocking.
    [0009] It can also be of greater complexity to fulfill the function of an input code, for example to prevent the activation of the device by unauthorized persons. According to embodiments, the method of the invention may comprise a step of triggering a function involving an interaction between at least one control object and a peripheral surface of the apparatus. This interaction can comprise an elementary action, and in particular an elementary action among those described previously. In this case, the sequence of actions according to the invention may have the effect of activating or selecting a particular function which uses as an input parameter an interaction between at least one control object and a peripheral surface. For example, the function may be a sound volume adjustment, and the action sequence may be used to activate a "slide" to adjust that volume. Thus, by default the slide is disabled and can not be accidentally activated if the sequence of actions has not been executed. According to embodiments, the method of the invention may further comprise steps of: defining an action sequence; and assigning said recorded action sequence to a predetermined function. Thus, the action sequence that triggers a function can be defined by the user. This definition can be done in different ways. It may include, for example: a recording step during which the user executes the sequence; an editing step during which the user defines a basic action sequence by means of appropriate editing tools.
    [0010] It may also include a validation step during which the user repeats the previously recorded custom action sequence to validate it. The definition of such a custom action sequence can be used for example to create a secret code, or to create custom shortcuts to trigger particular functions. In another aspect, there is provided an interface device for interacting with an electronic and / or computer apparatus comprising: - a control surface; at least one so-called peripheral surface arranged on the periphery of said control surface; a plurality of capacitive electrodes arranged at least along the control surface and arranged to detect control objects in a vicinity of said control surface and said at least one peripheral surface; Which control interface device comprises electronic and computing means arranged to: - detect a sequence of actions comprising a plurality of elementary actions performed at least in part sequentially, by at least one control object, at least in in contact with or opposite said at least one peripheral surface; - Trigger, according to said sequence of actions, at least one function in said apparatus. According to embodiments, the device according to the invention may comprise at least one peripheral surface devoid of capacitive electrodes. According to other embodiments, the device according to the invention 5 may comprise at least one peripheral surface provided with capacitive electrodes distinct from the capacitive electrodes of the control surface. According to embodiments, the device according to the invention may further comprise a polarized electrode guard layer with a so-called guard potential substantially equal to or exactly equal to a potential of excitation of said capacitive electrodes. According to embodiments, the device according to the invention may comprise capacitive electrodes arranged according to a matrix structure, each capacitive electrode realizing a capacitance measurement between said capacitive electrode and the control object or objects.
    [0011] In another aspect, there is provided an electronic and / or computer apparatus comprising a man-machine interface according to the invention. This apparatus may further comprise a display screen, the control surface being transparent and disposed on said display screen. This device can be a smartphone, tablet, smartwatch, wearable or any other type of portable device. This device can also be a control module integrated in an installation or a vehicle, or a computer control device (touchpad, trackpad, control or control interface), ... Description of the Figures and Embodiments 25 D Other advantages and particularities of the invention will appear on reading the detailed description of implementations and non-limiting embodiments, and the following appended drawings: FIG. 1 illustrates a smartphone-type electronic apparatus according to the invention with a display screen provided with a tactile interface, as held in the hand, FIG. 2 illustrates a side view of a smartphone type electronic apparatus according to the invention; FIG. 3 illustrates an embodiment of a detection electronics for a control interface according to the invention, FIG. 4 illustrates a general block diagram of the method according to the invention; FIG. 5 illustrates an exemplary implementation of the invention to perform a function of unlocking an apparatus, - FIG. 6 illustrates an exemplary implementation of the invention for performing a standby output function, - FIG. 7 illustrates examples of implementation of the invention to perform control functions or scrolling. It is understood that the embodiments or implementation 10 which will be described in the following are in no way limiting. In particular, it will be possible to imagine variants of the invention comprising only a selection of characteristics described subsequently isolated from the other characteristics described, if this selection of characteristics is sufficient to confer a technical advantage or to differentiate the invention with respect to the state of the prior art. This selection comprises at least one feature preferably functional without structural details, or with only a part of the structural details if this part alone is sufficient to confer a technical advantage or to differentiate the invention from the state of the prior art.
    [0012] In particular, all the variants and embodiments described are combinable with one another if there is nothing to prevent this combination from the technical point of view. In the figures, the elements common to several figures retain the same reference.
    [0013] With reference to FIG. 1 and in FIG. 2, there will be described an electronic device 12 according to the invention, designed to be held in hand. In the embodiment presented, this device is of the mobile phone or smartphone type. It is understood, however, that its features are in no way limiting. The described embodiments could equally well be implemented on a tablet computer or any similarly shaped electronic device. The apparatus 12 comprises a control surface 13 with transparent capacitive measuring electrodes 14 superimposed or integrated with a display screen. The display screen may for example be of the LCD (liquid crystal-based), OLED (organic light-emitting diode) type, and / or based on a technology which uses quantum dots ( "Quantum dots").
    [0014] The transparent capacitive measuring electrodes 14 are arranged on the control surface 13 in a matrix arrangement. These capacitive measuring electrodes 14 are arranged so as to be able to detect control objects 10, such as for example fingers 10, near or in contact with the control surface 13.
    [0015] They are made of a substantially transparent conductive material, such as, for example, ITO (indium-tin oxide) deposited on a dielectric material (glass or polymer). The display screen with the control surface 13 and the measurement electrodes 14 constitute a control interface which makes it possible to interact with the apparatus 12. According to an advantageous aspect of the invention, the control interface of the the apparatus 12 also includes peripheral detection zones 15 at the edge of the control surface 13 which are arranged in such a way as to allow more varied interactions with the user.
    [0016] These peripheral detection zones 15 are positioned so as to be accessible to control objects 10 corresponding to fingers of the hand 11 (or hands 11) holding the apparatus 12. In the embodiment shown in FIGS. . 1 and FIG. 2, the apparatus comprises two peripheral detection zones 15 located on the edge of the control surface 13. These peripheral detection zones 15 are located on either side of the control surface 13, outside the control surface 13. The display area, according to the long lengths of the apparatus 12. They extend on the face of the apparatus which supports the control surface 13, in the area usually referred to as "bezel". They also extend on the adjacent faces which constitute the sides of the apparatus (ie the faces which have an orientation substantially 90 degrees of the face of the control surface 13). In the embodiment shown, capacitive measuring electrodes of the periphery of the control surface 13 are used to detect control objects 10 in peripheral detection areas 15.
    [0017] Indeed, these capacitive electrodes are sensitive to the presence of control objects 10 beyond the limits of the control surface 13. By comparing their measurements with those obtained with electrodes located more inward of the surface of the control surface. 13, it is possible to determine that a detected control object is in a peripheral detection area 15, and not above the control surface 13, and to locate this control object 10 in the Peripheral detection zone 15. This detection mode is called an edge effect detection. In the embodiment shown, the device according to the invention is devoid of capacitive measuring electrodes in the peripheral detection areas 15. Referring to FIG. 3, we will now describe an exemplary embodiment of a detection electronics that allows for a control interface according to the invention.
    [0018] In this embodiment, the capacitive electrodes 14 can detect the presence and / or measure the distance of at least one control object 10 in their vicinity. In particular, these measuring electrodes 14 and their associated electronics are arranged so as to allow the simultaneous detection of several control objects 10 in different configurations, including in particular: control objects 10 in contact with and / or at a distance from the control surface 13; and / or - control objects 10 in contact with and / or facing the peripheral surfaces 15; The position of the control object (s) 10 is determined from the position of the measuring electrodes 14 which detect these control objects 10. The distance, or at least an information representative of this distance, between the control objects 10 and the electrodes 14 are determined from measurements of the capacitive coupling between these electrodes 14 and the control objects 10.
    [0019] This embodiment provides a sufficient measurement sensitivity to be able to detect and locate control objects 10 in contact with the control surface 13, or which evolve in the vicinity of this control surface 13. the form of guard electrodes or guard planes (not shown) are positioned along the rear face of the measuring electrodes 14 relative to the detection areas of the control objects 10. These guard elements have the function of avoiding parasitic electrical couplings between the measuring electrodes 14 and their environment, as will be explained later.
    [0020] These guard elements are also made of a substantially transparent conductive material, such as, for example, ITO (indium-tin oxide). They are separated from the measurement electrodes 14 by a layer of dielectric material. The measurement electrodes 14 are connected to electronic means 20 for capacitive measurement 37. These capacitive measurement electronic means 37 are made in the form of a floating bridge capacitive measurement system as described for example in the document WO 2011 / 015,794. The detection circuit comprises a so-called floating portion 36 whose reference potential 31, called guarding potential 31, oscillates with respect to the mass 33 of the overall system, or to the earth. The potential difference between the holding potential 31 and the ground 33 is generated by an excitation source, or an oscillator 34. The guard elements are connected to the guard potential 31.
    [0021] The floating portion 36 comprises the sensitive portion of the capacitive sensing shown in FIG. 3 by a charge amplifier. It may of course include other means of processing and signal conditioning, including digital or microprocessor-based, also referenced to the guard potential 31. These processing and conditioning means allow for example to calculate distance and pressure information from capacitive measurements. The electrical supply of the floating portion 36 is provided by floating power transfer means 35, comprising for example DC / DC converters. This capacitive measuring system makes it possible to measure capacitance information between at least one measuring electrode 14 and a control object 10. The control object 10 must be connected to a potential different from the guarding potential 31, such as by For example, the ground potential 33 is found in this configuration when the control object 10 is a finger of a user whose body defines a mass, or an object (such as a stylus) manipulated by this user. A set of analog switches or switches 30, controlled by electronic control means, makes it possible to select a measurement electrode 14 and to connect it to the capacitive detection electronics 37 to measure their coupling capacity with the object. The switches 30 are configured such that a measuring electrode 14 is connected to either the capacitive sensing electronics 37 or the guarding potential 31. The sensitive part of the detector is shielded. 32, which is connected to the guarding potential 31. Thus, a measuring electrode 14 connected by a switch 30 to the capacitive detection electronics 37 (or active measuring electrode 14) is surrounded by guard planes consisting at least of partly by inactive measuring electrodes 14 and by guard elements connected to the guarding potential 31. Since the active measuring electrode 14 is also at the guarding potential 31, Thus the appearance of parasitic capacitances between this electrode and its environment is rapid, so that only the coupling with the object of interest is measured with maximum sensitivity. The floating electronics 36 is connected at the output to the electronics of the apparatus 38 referenced to ground by electrical connections compatible with the reference potential difference. These links may include, for example, differential amplifiers or optocouplers. Of course, other embodiments of detection electronics can be implemented within the scope of the invention.
    [0022] In particular, it is possible to implement "self" type electronic detections with an active guard to guarantee a sufficient sensitivity to the electrodes 14. In this type of technique, the electronics are referenced to the general mass but the guard is biased to same potential as the electrodes 14.
    [0023] Referring to FIG. 4, we will now describe an embodiment of the method according to the invention. The method is implemented in a microcontroller or a microprocessor of the apparatus 12 which is at least partly dedicated to the operation of the human-machine interface.
    [0024] It implements a database 46 of predetermined action sequences assigned to particular functions. This database is stored for example in a non-volatile memory. The database 46 includes action sequences defined at the operating system level (for example Android, iOS or Windows) and / or at the application level. It can also include action sequences defined or recorded by the user. By way of nonlimiting example, the action sequences are defined in the form of lists or tables of elementary sequence data.
    [0025] These elementary sequence data comprise a set of descriptive fields or attributes, such as: - a type of elementary action: "tap", double "tap", long press, "swipe" , "Flick", displacement, "slide", "scroll" as well as actions performed remotely, in "hovering" (flyby) ...; - a duration (depending on the type of elementary action); a time interval or a range of time intervals separating it from the previous elementary action in the sequence; Location parameters in the peripheral zones 15 or on the control surface 13; - a pointer or a link to a function. To identify a sequence of actions, the method of the invention comprises a first initialization step 40 in which a new empty candidate sequence is created. It then comprises a step 41 for identifying an elementary action. Then it comprises a step 42 of construction of an action sequence 10 during which the elementary action with its position, time, ... attributes is added to the candidate sequence being constructed. The candidate sequence is then compared during a comparison step 43 with the sequences recorded in the database 46. If the candidate sequence corresponds to a complete recorded sequence, the process proceeds to an execution step 44 of the associated function. If the candidate sequence does not correspond to a complete recorded sequence, the method proceeds to an analysis step 45: if the candidate sequence corresponds to an incomplete recorded sequence, the method according to the invention goes back to the step of identification 41 of the following elementary action; if the candidate sequence does not correspond to an incomplete recorded sequence, the method according to the invention goes back to the initialization step 40. The current candidate sequence is rejected and a new empty candidate sequence is created. A "timeout" timeout is also introduced in the method for resetting the candidate sequence in the absence of new elementary actions for a predetermined duration. Of course, the elementary actions are also analyzed individually to trigger functions to which they would be associated individually, if any. With reference to FIG. 5, we will now describe an example of implementation of a sequence of actions according to the invention, to achieve a secure unlock code on a device type smartphone.
    [0026] The sequence implemented is as follows: 1) taken in hand with positioning of five control objects 10 in the form of five fingers of a hand 100, 101, 102, 103, 104, corresponding to five long supports; 5 2) holding the long press with four fingers 100, 101, 103, 104, performing a double "tap" 50 with the middle finger 102; 3) then executing a "slide" 51 with the thumb 100. If this sequence is identified, the function of unlocking the device is executed.
    [0027] Of course, the sequence to be executed may be more or less complex depending on the wishes of the user. It can be registered by the latter, so as to be personalized and kept secret. This release mode has a number of advantages. It can be executed with one hand, is easy to implement, and can be of a high security level. It is even possible to take into account the morphology of the user's hand, for increased security. Thus, in the example presented, the relative position of the fingers, which depends on the morphology of the hand, is taken into account for the validation of the long supports of step 1). On the other hand, it is preferable not to take into account the absolute position of the fingers along the peripheral surfaces so that the user can execute his code even without looking at the apparatus and without having to aim at particular positions. With reference to FIG. 6, an implementation example of a sequence of actions according to the invention will now be described, for performing a standby output function on a smartphone-type device. The purpose of this example is to implement a standby output function that can not be triggered accidentally on a device 12 without physical buttons since they are replaced by the sensitive peripheral zones 15. For example, following sequence: 1) double "tap" 60 on a peripheral surface, for example with index 101; 2) moving 61 on the control surface 13, for example with the thumb. This sequence triggers a wake-up function of the apparatus 12.
    [0028] Movement 61 may include (or not) a particular path. Thus, in standby mode, it is possible to keep active only the capacitive sensors 14 at the periphery of the sensitive surface 13 to limit consumption. The double "tap" 60 triggers the activation of the sensors of the sensitive surface 13 which can thus detect the displacement 61 if appropriate. With reference to FIG. 7, will now be described examples of implementation of sequences of actions that allow to perform adjustment functions or displacement in a robust and safe manner from the point of view of the risk of false triggering, by exploiting the peripheral zones 15. The purpose of these action sequences is to activate and operate a virtual slide-like button in a peripheral zone 15. In a first example, a sequence according to the invention is implemented to adjust a reproduction volume. sound. For this, we implement a sequence comprising: 1) a double "tap" 70 at any position along a peripheral surface 15; 2) a displacement 71 along the peripheral surface 15 starting from the same position. This sequence triggers a function of adjusting the sound of the apparatus which uses as the input parameter the displacement 71. In this case, an advantage of the invention is that it is possible to activate the adjustment function with a virtual button which is is located at any position (for example, one that falls naturally under the thumb 100) along a peripheral surface 15, but avoids false triggers because a displacement 71 alone would not activate the function. In another example, sequences according to the invention are implemented to create scrolling virtual buttons with the possibility of implementing different modes. For example, this mode of implementation can be implemented in a photo management application (gallery). In this case, a first sequence is implemented comprising: 1) a double "tap" 70 at any position along a peripheral surface 15; 2) a displacement 71 along the peripheral surface 15 starting from the same position. This sequence triggers an image scrolling function on the screen of the apparatus according to the amplitude or the stroke of the displacement 71. A second sequence is also implemented comprising: 1) a double tap 72 to any position along a peripheral surface 15; 2) a displacement 71 along the peripheral surface 15 corresponding to the opposite face of the apparatus 12. This sequence triggers a function of scrolling image files on the screen of the apparatus according to the amplitude or the race of the movement 71.
    [0029] Thus, a very simple scrolling function, or scrolling at two hierarchical levels, is implemented very simply. In this case, the invention brings a twofold advantage: the adjustment function can be activated with a virtual button which is at any position (for example that which falls naturally under the thumb) along a peripheral surface while avoiding false triggers because a displacement 71 alone would not activate the function; - The same displacement 71 can be very easily and intuitively assigned to two different functions: a displacement element by element or folder by folder.
    [0030] Of course, the invention is not limited to the examples which have just been described and numerous adjustments can be made to these examples without departing from the scope of the invention.
