Description

Title of the invention: Advanced keyboard data entry device forming in particular a payment terminal.

[0001] The invention relates to the technical field of data capture devices intended to form, in particular, payment terminals.

[0002] The technology already exists for a data entry device comprising a keyboard allowing a user to enter data. In the case of a data entry device forming a payment terminal, the keyboard allows, in particular, a user to enter a secret code enabling them to identify themselves during a payment.

[0003] In a keyboard, different so-called activatable areas are delimited. Each activatable area is intended to be activated by a user's finger. For example, a keyboard of the type in which the activatable areas are represented by keys forming raised bumps is known. According to another type of keyboard, the latter includes a touchscreen in which the activatable areas are delimited. A keyboard with a touchscreen offers a clear ergonomic advantage.

[0004] When the user is visually impaired or blind, it is important that they be able to identify the touch-sensitive areas. In the case of a physical keyboard, a visually impaired user can, for example, identify each key based on, firstly, a tactile marker on the keyboard, specifically on a particular key, and secondly, the position of each key relative to this marker, this position being identifiable by touch. In the case of a touchscreen keyboard, the means of assisting a visually impaired user in identifying the touch-sensitive areas are more complex.

[0005] However, it is observed that ordinary tactile means of assistance for a visually impaired user in identifying activatable areas sometimes lead to discomfort in use, or even to errors.

[0006] Furthermore, it is known to confirm to the user that they have activated an active zone by displaying an activation confirmation sign on a payment terminal screen. Of course, in the case of a visually impaired or blind user, access to visual information confirming that an active zone has indeed been activated is not possible. Thus, even if a visually impaired user correctly identifies the active zones on a keypad, it is necessary to provide means other than visual ones to confirm that an active zone on the keypad has been correctly activated. It is known to confirm that an active zone on the keypad has been correctly activated by audible means, but the effectiveness of these means is limited. Sound levels depend heavily on the noise pollution of the environment in which a user operates the keyboard.

[0007] The invention aims in particular to provide a data capture device that can form in particular a payment terminal, the ergonomics of which prioritize the sense of touch, which is easily usable by any type of user, in particular by a visually impaired or blind user.

[0008] To this end, the invention relates to a data capture device, of the type comprising:

[0009] - a keyboard in which different so-called activatable zones are delimited that a The user can selectively activate it with a finger.

[0010] - means for identifying each activatable zone that is activated by a user, referred to as activated zone identification methods,

[0011] characterized in that it further comprises:

[0012] - a haptic actuator capable of detecting pressure,

[0013] - means for controlling the haptic actuator as a function of pressure captured by the haptic actuator, these control means for the haptic actuator being electrically connected to the activated zone identification means so as to allow data transmission between the activated zone identification means and the control means for the haptic actuator,

[0014] the means for identifying the activated zone being rigidly coupled, on the one hand, to the keyboard and, on the other hand, to the haptic actuator,

[0015] the control means of the haptic actuator being configured so that the haptic actuator delivers a haptic effect to the keyboard based on the detection of the activation of an activatable zone by the activated zone identification means and the pressure exerted on this activated zone,

[0016] The control means for the haptic actuator being arranged on a main printed circuit board, the device comprising a housing body, the main printed circuit board being arranged in a protected space extending inside the housing body. In this way, the main printed circuit board, which performs essential functions of the device, can be protected against tampering.

[0017] When the haptic actuator is activated by its control means, it provides the keyboard with a haptic effect that targets the user's sense of touch. Because the activated zone identification means are rigidly coupled, on the one hand, to the keyboard and, on the other hand, to the haptic actuator, the haptic actuator is rigidly coupled to the keyboard. The haptic effect is delivered when a user places one of their fingers in contact with an activatable zone of the keyboard and, simultaneously, applies pressure to that activatable zone. Indeed, due to the rigid coupling between the keyboard, the activated zone identification means, and The haptic actuator detects pressure applied by the user to the keyboard's activatable area. The pressure-sensitive haptic actuator then controls the haptic actuator to provide haptic feedback to the keyboard based on the detection of an activated area by the activated area identification system and the pressure applied to that area by the haptic sensor. This haptic feedback is accessible to all users, including visually impaired or blind individuals, who can therefore use this data entry device more easily.

[0018] The fact that the activated zone identification means can transmit data to the control means of the haptic actuator makes it possible to have a data entry device having a keyboard with several activatable zones, in particular with several keys, producing a haptic effect targeting the user's sense of touch, this by using only a single haptic actuator common to all the activatable zones or to a group of activatable zones, rather than a haptic actuator associated with each activatable zone.

[0019] Other optional characteristics of this data capture device, taken alone or in combination, will be specified below.

[0020] The activated zone identification means are rigidly coupled to the keyboard via a coupling element, generally in the form of a plate, having a face, referred to as the bottom face, for connection with an active face of the haptic actuator, and a face, referred to as the top face, facing all the activatable zones of the keyboard and carrying the activated zone identification means. Thus, the elements mechanically connecting the keyboard and the haptic actuator are sufficiently rigid and incompressible to, on the one hand, transmit to the haptic sensor the pressure exerted by a user's finger on the keyboard and, on the other hand, transmit to the user's finger in contact with the keyboard a haptic effect sufficient to be clearly felt by the user.

[0021] The means for identifying the activated zone include a capacitive sensor carried on a flexible printed circuit board mounted on the top face of the coupling member. The flexible printed circuit board, being thin and therefore compact in the axial stacking direction of this flexible printed circuit board and the coupling member, is easy to arrange on the top face of the coupling member.

[0022] The coupling element is formed by the support for the conductive elements of a rigid printed circuit board, the activated zone identification means comprising a capacitive sensor carried on the top face of the coupling element formed by the support for the conductive elements of the rigid printed circuit board. It is observed Indeed, a rigid printed circuit board forms a sufficiently rigid component to, on the one hand, transmit to the haptic sensor the pressure exerted by a user's finger on the keyboard and, on the other hand, transmit to the user's finger in contact with the keyboard a haptic effect sufficient to be clearly felt by the user.

[0023] The underside of the coupling member is connected to the active face of the haptic actuator by a connecting member having first and second adhesive surfaces bonded respectively to the underside of the coupling member and the active face of the haptic actuator. Because this connecting member is positioned between the underside of the coupling member and the active face of the haptic actuator, the material of this connecting member can be chosen independently of the material of the coupling member, so that it has incompressibility and rigidity properties suitable for, on the one hand, transmitting to the haptic sensor the pressure exerted by a user's finger on the keyboard and, on the other hand, transmitting to the user's finger in contact with the keyboard a haptic effect sufficient to be clearly felt by the user.Furthermore, the adhesive surfaces facilitate the transmission of pressure and tension effects from vibrations propagated to the coupling element.

[0024] The keyboard includes a contact surface with a user's finger, this contact surface having indentations representing the keyboard keys. These indentations create areas of reduced thickness on the keyboard that facilitate the detection, by the activated zone identification means, of a finger's contact with an activatable area of ​​the keyboard. Indeed, the smaller the distance between the user's finger and the activated zone identification means, the more effective the detection of the finger's contact with the activated area.

[0025] The keyboard includes a touch screen forming a contact face with a user's finger, this touch screen being able to define at least one configuration of activatable zones, preferably two configurations of activatable zones.

[0026] The invention also relates to a payment terminal comprising a data entry device as defined above. Brief description of the figures

[0033] [Fig.6] is a view similar to [Fig.5], in which the screen is in a second portrait configuration. Detailed description

[0034] Figures 1 to 3 show a payment terminal according to the invention, designated by the general reference 10, comprising a housing body 12, partially shown, and a data entry device 14 according to a first embodiment of the invention.

[0035] The data capture device 14 includes a base 16 partially delimiting, on the one hand, the housing body 12 and, on the other hand, a space 18, extending inside the housing body 12.

[0036] This space 18 is protected against break-ins, for example, by a break-in detection coating that at least partially covers the walls delimiting this space 18. The break-in detection coating is formed, for example, by a flexible printed circuit board. In this type of board, a dense network or lattice of fine conductors printed on the board is connected in a manner known per se to an electronic circuit that triggers an alarm as soon as damage to a conductor is detected, in particular by destruction or short-circuiting.

[0037] The data input device 14 also includes a keyboard 20 in which are delimited different so-called activatable zones Z which a user can selectively activate with a finger.

[0038] In the first embodiment of the data entry device 14, the keypad 20 has a general plate shape. The keypad 20 includes a face 20A intended to be in contact with a user's finger. This contact face 20A comprises indentations 22 representing keys of the keypad 20, forming the activatable zones Z that a user can selectively activate by placing a finger in a chosen indentation 22. The contact of the finger with the chosen indentation 22 is detected by activated zone identification means, which will be described subsequently.

[0039] The data capture device 14 further includes a haptic actuator 24, capable of detecting pressure, coupled to the keyboard 20. In the example described, the haptic actuator 24 is a piezoelectric actuator, for example of the type described in US 11,653,569. Such an actuator 24 includes a piezoelectric element, forming a pressure sensor, having very high deformation kinetics. Alternatively, The haptic actuator 24 could be a linear resonant actuator, which uses a magnetic mass suspended by springs, combined with a pressure-sensing element, for example a piezoelectric element, or a vibrating motor with an eccentric rotating mass combined with a pressure-sensing element, for example a piezoelectric element. The piezoelectric haptic actuator has the advantage of being compact.

[0040] As can be seen in particular in figures 2 and 3, the haptic actuator 24 is rigidly coupled to the keyboard 20 by means of a coupling element 26, generally in the form of a plate.

[0041] Thus, the coupling member 26 is provided with a face, called the bottom face 26A, for connection with an active face 24A of the haptic actuator, and a face, called the top face 26B, opposite all the activatable areas Z of the keyboard 20, that is to say opposite all the presses 22.

[0042] Furthermore, the underside of the coupling member 26 is connected to the active face 24A of the haptic actuator 24 by a connecting member 28 having first and second adhesive faces F glued respectively on the underside 26A of the coupling member 26 and the active face 24A of the haptic actuator 24.

[0043] By haptic actuator 24 coupled "rigidly" to the keyboard 20, it is understood that the components mechanically connecting the keyboard 20 and the haptic actuator 24 are sufficiently rigid and incompressible to transmit to the user's finger in contact with the keyboard 20 a haptic effect sufficient to be clearly felt by the user. Sufficient rigidity of this coupling can be obtained by successive tests of materials forming the components mechanically connecting the keyboard 20 and the haptic actuator 24, more particularly forming the coupling member 26 and the connecting member 28.

[0044] In the described example, the active face 24A of the haptic actuator 24 and the connecting member 28 are arranged substantially directly above the center of the coupling member 26. In this example, the coupling member 26 can be considered sufficiently rigid if, within the range of possible pressure that a user's finger can exert on the point of the keypad 20 furthest from its center, the deflection of the keypad 20 at this pressure point does not exceed 1 millimeter. This maximum deflection defines a minimum clearance to prevent, during use of the keypad 20, any unwanted contact between the keypad 20 or the coupling member 26 and the base 16 or any element, for example a connector, interposed between, on the one hand, this base 16 and, on the other hand, the keypad 20 or the coupling member 26.

[0045] Thus, in order to ensure sufficient rigidity, the coupling member 26 is preferably made of a metallic material. Alternatively, the coupling member 26 may be formed from a material similar to that usually used to form the support for the conductive elements of a rigid printed circuit board, namely a fiberglass-reinforced epoxy resin composite, for example of type FR4 in accordance with the standard defined by NEMA (National Electrical Manufacturers Association).

[0046] Similarly, in order to guarantee sufficient rigidity, the connecting member 28 is made of a material that is relatively incompressible within the range of pressure that a user's finger can exert on the keyboard 20. Preferably, a relatively thin connecting member 28 will be chosen to limit any possible damping effect.

[0047] To ensure good transmission to the coupling member 24 of the pressure exerted by a user's finger on the keyboard 20, this keyboard 20 is preferably made of plastic. It should be noted that the indentations 22, forming areas of reduced thickness in the keyboard 20, facilitate the transmission of the pressure exerted by the user to the coupling member 24.

[0048] The data capture device 14 also includes means for identifying each activatable zone Z that is activated by a user, called activated zone identification means.

[0049] In the embodiment shown in Figures 1 to 3, the activated zone identification means comprise a capacitive sensor 30 carried by a flexible printed circuit board 32 carried by the top face 26B of the coupling member 26. The flexible printed circuit board 32 is therefore interposed between the top face 26B of the coupling member 26 and a face 20B of the keypad 20 opposite the face 20A of this keypad 20 in which the recesses 22 are formed. Thus, the activated zone identification means, comprising the capacitive sensor 30, are rigidly coupled, on the one hand, to the keypad 20 and, on the other hand, to the haptic actuator 24 capable of detecting pressure. More specifically, the means for identifying the activated zone, including the capacitive sensor 30, are rigidly coupled to the keypad 20 via the coupling element 26, which is generally in the form of a plate.

[0050] As can be seen in [Fig. 3], electronic control means 34 for the haptic actuator 24, based on the pressure detected by the haptic actuator 24, are arranged on a main printed circuit board 36, for example, of the rigid type but which can also be flexible. It should be noted that this main printed circuit board 36 is arranged in the tamper-proof compartment 18.

[0051] The haptic actuator 24 is electrically connected to the main printed circuit board 36 so as to allow data transmission, in particular the reception of control signals from the control means 34.

[0052] The control means 34 are electrically connected to the activated zone identification means so as to allow data transmission between these activated zone identification means and the control means 34.

[0053] Indeed, the capacitive sensor 30 of the activated zone identification means is electrically connected to the main printed circuit 36, on which the control means 34 are arranged, by connection means including for example a flexible connector 38 extending between rigid connectors 40, one of which, integral with the main printed circuit 36, is schematically shown on [Fig.3].

[0054] The means 34 are configured to control the haptic actuator 24 so that this haptic actuator delivers a haptic effect to the keyboard 20 as a function of the detection of the activation of an activatable area Z, in particular a depress 22, by the activated area identification means, in particular by the capacitive sensor 30, and of the pressure exerted on this activated area by the finger of a user.

[0055] It will be noted, with reference in particular to Figures 2 and 3, that the keypad 20, the capacitive sensor 30, the coupling member 26, the linking member 28, and the haptic actuator 24 are stacked one on top of the other in such a way as to form a stack in a direction referred to as axial. In what follows, a direction orthogonal to the axial direction will be referred to as lateral. Furthermore, it will be noted that the means for identifying the activated zone, including the capacitive sensor 30, have a dual function:

[0056] that of producing a signal specific to each activatable zone whose activation is detected, so as to be able to identify and deliver to a central unit of the payment terminal 10 a series of information constituting, for example, a user confidential code, and

[0057] that of participating in a rigid stack, comprising these means of identifying the activated zone, the coupling member 26 and the linking member 28, connecting the keyboard 20 to the haptic sensor 24, this for the proper transmission of pressure and haptic effect between this keyboard 20 and haptic sensor 24.

[0058] The data entry device 14 further includes a frame 42 that contributes to the axial and lateral positioning of the keyboard 20 relative to the base 16. For this purpose, the keyboard 20 has a peripheral rebate 44 extending vertically from a counter-rebate 46 of the frame 42. An annular seal 48, preferably made of elastomer, extends between the peripheral rebate 44 of the frame 20 and the counter-rebate 46 of the frame 42. Preferably, a groove 46G is provided in the counter-rebate 46. This groove 46G forms a positioning recess for the seal 48. If necessary, as shown in [Fig. 3], an annular shim 50 contributing to the axial positioning of the keyboard 20 is interposed between the seal 48 and one of the rebates 44 and counter-rebates 46. namely, as in the illustrated example, between the joint 48 and the peripheral rebate 44 of the frame 20.

[0059] The frame 42 is fixed in a manner known per se to the base 16, for example by screwing.

[0060] The data capture device 14 according to the invention is simple to use. The operating steps of this device, 14 in particular, are linked to The invention is as follows. To activate an activatable zone Z of the keyboard 20, more particularly a key formed by a depressment 22 of the keyboard 20, the user places one of their fingers, for example the index finger of their right hand, in contact with a depressment 22, by exerting pressure on this depressment 22. Due to the rigid coupling between the keyboard 20, the means for identifying the activated zone including the capacitive sensor 30, and the haptic actuator 24, the pressure exerted by the user's finger on the activatable zone Z of the keyboard 20 is detected by the haptic actuator 24 which is capable of capturing this pressure.Thus, the activation of an activatable zone Z is detected by the capacitive sensor 30, and pressure exceeding a reference threshold is detected by the haptic actuator 24. The means 34 control the haptic actuator 24 so that it delivers a haptic effect to the keypad 20, which is a function of the detection of the user's finger contact and the pressure exerted on the keypad 20. The user then perceives the haptic effect and thus obtains confirmation of the activation of the selected key press 22, which is particularly relevant when the user is visually impaired or blind. The keypad 20 may optionally include a raised element serving as a guide to facilitate the location of each key press 22 for a visually impaired or blind user by its relative position with respect to the raised element.

[0061] Figure 4 shows a data capture device 14 according to a second embodiment of the invention.

[0062] On this [Fig.4], elements analogous to those in the preceding figures are designated by identical references.

[0063] In the data capture device 14 according to the second embodiment, the coupling member 26 is formed by the support for the conductive elements of a rigid printed circuit board, called the secondary printed circuit board. Preferably, the support for the conductive elements of the secondary printed circuit board is made of FR4-type material. Furthermore, the capacitive sensor 30 of the activated zone identification means is carried on the top face 26B of the coupling member 26 formed by the support for the conductive elements of the rigid printed circuit board. Preferably, the secondary printed circuit board is arranged in a space of the data capture device 14 that is protected against tampering, for example, by a tamper-proof coating comprising a flexible printed circuit board sheet.In this type of sheet, a dense network or lattice of fine conductors printed on the sheet is connected in a way known per se to an electronic circuit that triggers an alarm as soon as a conductor degradation is detected, in particular by destruction or short-circuiting.

[0064] In the data capture device 14 according to the second embodiment, the secondary printed circuit board carrying the capacitive sensor 30 is electrically connected to the main printed circuit board 36 by connection means including, for example a flexible connector 38 extending between rigid connectors 40, one of which is attached to the main printed circuit 36 ​​and the other to the secondary printed circuit forming the coupling element 26. The flexible connector 38 is formed, for example, by a flexible circuit, such as a circuit designated by the English acronym FPC for "Flexible Printed Circuit", or by a flexible ribbon cable.

[0065] Figures 5 and 6 show a data capture device 14 according to a third embodiment of the invention.

[0066] In Figures 5 and 6, elements structurally or functionally analogous to those in the preceding figures are designated by identical reference numerals. Furthermore, the data entry device 14 according to this third embodiment includes elements common to or similar to those of the preceding embodiments, which are not shown in Figures 5 and 6 but will be referred to below using the reference numerals employed to describe the preceding embodiments.

[0067] In this case, the keyboard 20 includes a touchscreen 52 forming a contact surface with a user's finger. This screen 52 can define at least one configuration of activatable zones Z, preferably two configurations as shown respectively in Figures 5 and 6. Thus, [Fig. 5] represents a first configuration of activatable zones Z referred to as "landscape" and [Fig. 6] represents a second configuration of activatable zones Z referred to as "portrait".

[0068] Software means programmed for example in a central unit carried by the main printed circuit board 36 allow switching from the "landscape" configuration to the "portrait" configuration according to data provided by a gyroscopic sensor or an accelerometer carried for example by the main printed circuit board.

[0069] The touch screen 52 is connected, in a manner known per se, to the capacitive sensor 30 of the activated zone identification means in order to allow, according to the configuration of activatable zones Z, the identification of an activated zone by a user.

[0070] In the example illustrated in Figures 5 and 6, the Z-activated zones form, at least in part, keys of a numeric keypad. The areas between the keys can also form Z-activated zones.

[0071] Thus, the haptic sensor 24 can be controlled so as to deliver a specific haptic effect to the activatable area Z in contact with the user's finger so that, on the one hand, the activation of an activatable area Z forming a key of the numeric keypad generates a click effect, and that, on the other hand, the activation of an activatable area Z located between the keys of the numeric keypad generates a vibration effect.

[0072] The invention is not limited to the embodiments presented, and other embodiments will be obvious to those skilled in the art. In particular, the data entry device according to the invention may include a keyboard comprising a first A group of activatable zones representing numbers for composing PIN codes and a second group of activatable zones representing non-confidential function keys, such as an input confirmation key and an input deletion key. In this case, the first group of activatable zones may be associated with a first haptic actuator common to this first group, and the second group of activatable zones may be associated with a second haptic actuator common to this second group. Furthermore, the data entry device according to the invention can be used on a component other than a payment terminal. In particular, it could be used on any component intended for entering an identification code, such as an access control device for a secure enclosure. List of references
