Abstract
Description
Title of the invention: Improved keyboard data entry device forming in particular a payment terminal.
[0001] The invention relates to the technical field of data entry devices intended in particular to form payment terminals.
[0002] A data entry device comprising a keyboard allowing a user to enter data is already known in the prior art. In the case of a data entry device forming a payment terminal, the keyboard allows a user in particular to enter a secret code allowing them to identify themselves during a payment.
[0003] In a keyboard, different so-called activatable zones are delimited. Each activatable zone is intended to be activated by a user's finger. For example, a keyboard of the type in which the activatable zones are materialized by keys forming projecting reliefs is known. According to another type of keyboard, the latter comprises a touch screen in which the activatable zones are delimited. A touch screen keyboard has a certain ergonomic interest.
[0004] When the user is visually impaired or blind, it is appropriate for the latter to be able to identify the activatable zones by contact with his finger. In the case of a keypad, the visually impaired user can for example identify each key as a function, on the one hand, of a tactile marker arranged on the keyboard, in particular on a key of this keyboard, and, on the other hand, of 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 activatable zones are more complex.
[0005] However, it is observed that ordinary tactile means of assisting a visually impaired user in identifying the activatable zones lead in certain cases to discomfort in use, or even to errors.
[0006] Furthermore, it is known to confirm to the user that he has activated an activatable zone by displaying a sign confirming activation of the activatable zone on a screen of the payment terminal. Of course, in the case of a visually impaired or blind user, access to visual information confirming that an activatable zone has been activated is not possible. Thus, even if a visually impaired user correctly identifies the activatable zones on a keyboard, it is appropriate to provide means other than visual ones confirming that an activatable zone of the keyboard has been correctly activated. It is known to confirm that an activatable zone of the keyboard has been correctly activated by audible means, but the effectiveness of these means Sound pollution depends a lot on the noise pollution of the environment in which a user operates the keyboard.
[0007] The invention aims in particular to propose a data entry device which can form in particular a payment terminal, the ergonomics of which favor 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 entry device, of the type comprising:
[0009] - a keyboard in which different zones are delimited, called activatable zones, which a user can selectively activate with one finger,
[0010] - means for identifying each activatable zone which is activated by a user, so-called activated area identification means,
[0011] characterized in that it further comprises:
[0012] - a haptic actuator capable of sensing pressure,
[0013] - means for controlling the haptic actuator as a function of pressure captured by the haptic actuator, these means for controlling the haptic actuator being electrically connected to the activated zone identification means so as to allow the transmission of data between the activated zone identification means and the means for controlling the haptic actuator,
[0014] the activated zone identification means 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 as a function of the detection of the activation of an activatable zone by the activated zone identification means and of the pressure exerted on this activated zone,
[0016] the control means of the haptic actuator being arranged on a so-called main printed circuit, the device comprising a housing body, the main printed circuit being arranged in a protected space extending inside the housing body. In this way, the main printed circuit, which provides essential functions of the device, can be protected against infringements.
[0017] When the haptic actuator is activated by the control means of this actuator, it delivers to the keyboard a haptic effect which targets the user's sense of touch. Because the activated area 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 puts one of his fingers in contact with an activatable area of the keyboard and, simultaneously, exerts pressure on this activatable area. Indeed, because of the rigid coupling between the keyboard, the activated area identification means, and the haptic actuator, the pressure exerted by the user on the activatable zone of the keyboard is detected by the haptic actuator capable of sensing pressure. Thus, the control means of the haptic actuator can control this haptic actuator so that it delivers a haptic effect to the keyboard depending on the detection of the activation of an activatable zone by the activated zone identification means and the pressure, detected by the haptic sensor, exerted on this activated zone. The haptic effect is perceived by any type of person, in particular a visually impaired or blind person who can therefore more easily use this data entry device.
[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 features 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 by means of a coupling member, generally in the form of a plate, provided with a face, called the bottom, for connection with an active face of the haptic actuator, and a face, called the top, facing all of the activatable zones of the keyboard and carrying the activated zone identification means. Thus, the members 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 activated area identification means comprise a capacitive sensor carried by a flexible printed circuit carried by the top face of the coupling member. The flexible printed circuit, of low thickness and therefore not very bulky in the axial stacking direction of this flexible printed circuit and the coupling member, is easy to arrange on the top face of the coupling member.
[0022] The coupling member is formed by the support of the conductive elements of a rigid-type printed circuit, the activated zone identification means comprising a capacitive sensor carried by the top face of the coupling member formed by the support of the conductive elements of the rigid-type printed circuit. We observe in fact, a rigid printed circuit forms a sufficiently rigid member 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 bottom face of the coupling member is connected to the active face of the haptic actuator by a connecting member provided with first and second adhesive faces glued respectively to the bottom face of the coupling member and the active face of the haptic actuator. Because this connecting member is attached between the bottom face 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 properties of incompressibility and rigidity adapted 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.Furthermore, the adhesive faces facilitate the transmission of the pressure and traction effects of the vibrations propagated to the coupling member.
[0024] The keyboard comprises a contact face with a user's finger, this contact face comprising depressions materializing keys of the keyboard. Thus, the depressions form zones of reduced thickness of the keyboard which promote the detection by the activated zone identification means of the contact of a finger on an activatable zone 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 contact of the finger on the activated zone.
[0025] The keyboard comprises 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

[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 entry device 14 comprises 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 which at least partially covers the walls which delimit this space 18. The break-in detection coating is formed, for example, by a sheet forming a flexible printed circuit. In this type of sheet, a dense network or lattice of fine conductors printed on the sheet is connected in a manner known per se to an electronic circuit triggering an alarm as soon as damage to a conductor is detected, in particular by destruction or short-circuiting.
[0037] The data entry device 14 also comprises a keyboard 20 in which different zones Z, called activatable zones, are delimited and which a user can selectively activate with a finger.
[0038] In the first embodiment of the data entry device 14, the keyboard 20 has a general plate shape. The keyboard 20 comprises a face 20A intended to be in contact with the finger of a user. This contact face 20A comprises depressions 22 materializing keys of the keyboard 20 forming the activatable zones Z that a user can selectively activate by placing a finger in a chosen depression 22. The contact of the finger with the chosen depression 22 is detected by activated zone identification means which will be described later.
[0039] The data entry device 14 also comprises a haptic actuator 24, capable of sensing 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 comprises a piezoelectric element, forming a pressure sensor, having very high deformation kinetics. As a variant, the haptic actuator 24 could be a resonant linear actuator, which uses a magnetic mass suspended by springs, associated with a pressure sensor element, for example a piezoelectric element, or a vibrating motor with an eccentric rotating mass associated with a pressure sensor 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 member 26, in the general shape 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 of the activatable zones Z of the keyboard 20, that is to say opposite all of the depressions 22.
[0042] Furthermore, the bottom face of the coupling member 26 is connected to the active face 24A of the haptic actuator 24 by a connecting member 28 provided with first and second adhesive faces F glued respectively to the bottom face 26A of the coupling member 26 and the active face 24A of the haptic actuator 24.
[0043] By haptic actuator 24 “rigidly” coupled to the keyboard 20, it is meant that the members mechanically connecting the keyboard 20 and the haptic actuator 24 to each other 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 may be obtained by successive tests of materials forming the members mechanically connecting the keyboard 20 and the haptic actuator 24 to each other, more particularly forming the coupling member 26 and the connecting member 28.
[0044] In the example described, 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 the case of this example, it can be considered that the coupling member 26 is sufficiently rigid if, in the possible pressure range that a user's finger can exert on the point of the keyboard 20 furthest from its center, the deformation arrow of the keyboard 20 at this pressure point does not exceed 1 millimeter. This value not to be exceeded by the arrow defines a minimum clearance making it possible to avoid, when using the keyboard 20, any parasitic contact of this keyboard 20 or of the coupling member 26 with the base 16 or an element, for example a connector, interposed between, on the one hand, this base 16 and, on the other hand, the keyboard 20 or the coupling member 26.
[0045] Thus, in order to ensure sufficient rigidity, the coupling member 26 is preferably formed from a metallic material. Alternatively, the coupling member 26 may be formed from a material similar to that normally used to form the support for the conductive elements of a rigid-type printed circuit, namely a fiberglass-reinforced epoxy resin composite, for example of the FR4 type 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 relatively incompressible material in the possible pressure range 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 will be noted that the depressions 22, forming zones of reduction in thickness of the keyboard 20, promote the transmission of the pressure exerted by the user to the coupling member 24.
[0048] The data entry device 14 also comprises means for identifying each activatable zone Z which 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 32 carried by the top face 26B of the coupling member 26. The flexible printed circuit 32 is therefore interposed between the top face 26B of the coupling member 26 and a face 20B of the keyboard 20 opposite the face 20A of this keyboard 20 in which the depressions 22 are formed. Thus, the activated zone identification means, comprising the capacitive sensor 30, are rigidly coupled, on the one hand, to the keyboard 20 and, on the other hand, to the haptic actuator 24 capable of sensing pressure. More particularly, the activated zone identification means, comprising the capacitive sensor 30, are rigidly coupled to the keyboard 20 via the coupling member 26, in the general form of a plate.
[0050] As can be seen in [Fig. 3], electronic means 34 for controlling the haptic actuator 24, as a function of the pressure sensed by the haptic actuator 24, are arranged on a printed circuit 36 called the main circuit, for example of the rigid type but which can also be flexible. It will be noted that this main printed circuit 36 is arranged in the space 18 protected against break-ins.
[0051] The haptic actuator 24 is electrically connected to the main printed circuit 36 so as to allow the transmission of data, in particular the reception of control signals coming from the control means 34.
[0052] The control means 34 are electrically connected to the activated zone identification means so as to allow the transmission of data 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 comprising for example a flexible connector 38 extending between rigid connectors 40, one of which, integral with the main printed circuit 36, is shown diagrammatically in [Fig. 3].
[0054] The means 34 are configured to control the haptic actuator 24 so that this haptic actuator delivers to the keyboard 20 a haptic effect as a function of the detection of the activation of an activatable zone Z, in particular of a depression 22, by the activated zone identification means, in particular by the capacitive sensor 30, and of the pressure exerted on this activated zone by the finger of a user.
[0055] It will be noted, with particular reference to FIGS. 2 and 3, that the keyboard 20, the capacitive sensor 30, the coupling member 26, the connecting member 28 and the haptic actuator 24 are stacked respectively on top of each other so as to form a stack in a so-called axial direction. In what follows, a direction orthogonal to the axial direction will be referred to as lateral. Furthermore, it will be noted that the activated zone identification means comprising 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 confidential user code, and
[0057] that of participating in a rigid stack, comprising these activated zone identification means, the coupling member 26 and the connecting member 28, connecting the keyboard 20 to the haptic sensor 24, this for the good transmission of the pressure and the haptic effect between these keyboard 20 and haptic sensor 24.
[0058] The data entry device 14 also comprises a frame 42 participating in the axial and lateral positioning of the keyboard 20 relative to the base 16. For this purpose, the keyboard 20 comprises a peripheral rebate 44 extending in line with 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 formed in the counter rebate 46. This groove 46G forms a positioning housing for the seal 48. If necessary, as shown in [Fig. 3], an annular shim 50 participating in the axial positioning of the keyboard 20 is interposed between the seal 48 and one of the rebate 44 and counter rebate 46, namely, as in the example illustrated, between the seal 48 and the peripheral groove 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 entry device 14 according to the invention is simple to use. The operating stages of this device 14 more particularly linked to the invention are as follows. To activate an activatable zone Z of the keyboard 20, more particularly a key formed by a depression 22 of the keyboard 20, the user places one of his fingers, for example the index finger of his right hand, in contact with a depression 22, by exerting pressure on this depression 22. Due to the rigid coupling between the keyboard 20, the activated zone identification means comprising 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 being detected by the capacitive sensor 30 and a pressure greater than a reference threshold being detected by the haptic actuator 24, the means 34 control the haptic actuator 24 so that it delivers to the keyboard 20 a haptic effect which is a function of the detection of the contact of the user's finger and the pressure which he exerts on the keyboard 20. The user then perceives the haptic effect and thus obtains a confirmation of the activation of the selected depression 22, which is particularly relevant when the user is visually impaired or blind. The keyboard 20 may, if necessary, comprise a raised means forming a reference to facilitate the location of each depression 22 by a visually impaired or blind user by the relative position of this depression 22 with respect to the raised means.
[0061] [Fig.4] shows a data entry device 14 according to a second embodiment of the invention.
[0062] In this [Fig.4], the elements similar to those of the previous 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 of the conductive elements of a rigid-type printed circuit, called a secondary printed circuit. Preferably, the support of the conductive elements of the secondary printed circuit is made of FR4 type material. Furthermore, the capacitive sensor 30 of the activated zone identification means is carried by the top face 26B of the coupling member 26 formed by the support of the conductive elements of the rigid-type printed circuit. Preferably, the secondary printed circuit is arranged in a space of the capture device 14 protected against break-ins, for example by a break-in detection coating comprising a sheet forming a flexible printed circuit.In this type of sheet, a dense network or lattice of fine conductors printed on the sheet is connected in a manner known per se to an electronic circuit triggering an alarm as soon as damage to a conductor 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 carrying the capacitive sensor 30 is electrically connected to the main printed circuit 36 by connection means comprising for example a flexible connector 38 extending between rigid connectors 40, one of which is secured to the main printed circuit 36 and the other is secured to the secondary printed circuit forming the coupling member 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 entry device 14 according to a third embodiment of the invention.
[0066] In these figures 5 and 6, the elements structurally or functionally similar to those of the preceding figures are designated by identical references. Furthermore, the data capture device 14 according to this third embodiment comprises elements common or similar to those of the preceding embodiments which are not shown in figures 5 and 6 but which will be discussed below using the references used to describe the preceding embodiments.
[0067] In this case, the keyboard 20 comprises a touch screen 52 forming a contact face 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 FIGS. 5 and 6. Thus, [Fig. 5] represents a first configuration of activatable zones Z called "landscape" and [Fig. 6] represents a second configuration of activatable zones Z called "portrait".
[0068] Software means programmed for example in a central unit carried by the main printed circuit 36 make it possible to switch from the “landscape” configuration to the “portrait” configuration depending on data provided by a gyroscopic sensor or an accelerometer carried for example by the main printed circuit.
[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 a zone activated by a user.
[0070] In the example illustrated in Figures 5 and 6, the activatable zones Z form at least in part keys of a numeric keypad. The zones between the keys can also form activatable zones Z.
[0071] Thus, the haptic sensor 24 can be controlled so as to deliver a haptic effect specific to the activatable zone Z in contact with the user's finger so that, on the one hand, the activation of an activatable zone Z forming a key of the numeric keypad generates a click effect, and that, on the other hand, the activation of an activatable zone 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 become clear to those skilled in the art. In particular, the data entry device according to the invention may comprise a keyboard comprising a first group of activatable zones materializing numbers intended to compose confidential codes and a second group of activatable zones materializing non-confidential functional keys, such as an entry validation key and an entry deletion key. In this case, it may be provided that the first group of activatable zones is associated with a first haptic actuator common to this first group and that the second group of activatable zones is associated with a second haptic actuator common to this second group. Furthermore, the data entry device according to the invention may be used on a device other than a payment terminal. In particular, it could equip any device intended for entering an identification code, such as a device for opening access to a secure enclosure. List of references
