- PDAs personal digital assistants
- ATMs ATMs or cash registers.
- a touch screen represents for example a virtual keyboard for the validation of a confidential code, or the amount of a transaction.
- a disadvantage of these electronic payment terminals lies in the fact that it does not allow a blind user to use them. Indeed, unlike electronic payment terminals comprising a screen and a keyboard in which the keys are embossed and some have a tactile location on their surface (including the digit 5, and keys validation, correction, or cancellation), each key on the virtual keyboard of an electronic payment terminal comprising a touch screen is detectable only visually.
- an object of the invention in at least one of its embodiments, is to provide a portable device comprising a touch screen that is usable by any user, including a blind user.
- the invention thus aims to provide such a device which is also ergonomic for the user, whether or not blind.
- Another object of the invention is to provide such a device which is inexpensive and easy to manufacture.
- Yet another object of the invention is to provide such a device which complies with the safety standards in force in the field of application of the device.

- the registration information may for example mean that the location where it is located is in the middle of the width or the height (in the middle of a side) of the screen, or vis-à-vis a particular area of a touch zone with which the screen is equipped (a corner, a key of a keyboard represented on the screen, etc.).
- Such a portable device is in particular an electronic payment terminal, whose screen can represent a virtual keyboard, for example for the entry of a confidential code, or a transaction amount.
- the registration information appears in relief with respect to at least one surface of said device.
- such a device is provided with means for inactivating the display of said touch screen.
- the invention when the device is in the mode of use by a blind user, the invention provides a security that nothing is displayed on the touch screen, to the extent that a blind user does not need any display on the touch screen. In this way, an ill-intentioned person observing the blind user (for example when the user enters his PIN code) without the latter being aware of it, can not deduce from his observation the keys activated by the blind user.
- such a device also comprises at least one key outside said touch screen.
- the registration information corresponds to a mark materializing a boundary between two distinct virtual regions of the touch screen.
- a tracking information makes it possible not to represent a virtual region of the screen but to materialize a border between two virtual regions of the touch screen, a region that can correspond to a key, or a set of keys.
- the user knowing the predefined organization of these regions, can locate the regions themselves on the touch screen, for example keys of a virtual keyboard in a case where a region corresponds to a key.
- the marker materializes a border between two virtual keys of said touch screen.
- a marker makes it possible to materialize a border between two keys of a touch screen, representing for example a virtual keyboard.
- the user knowing the predefined organization of the keys on the touch screen, can locate each of the keys by identifying the boundaries between them.
- the borders may be materialized by a short line, perpendicular to the outer edge of the touch screen.
- twelve markers make it possible to materialize the boundaries between the digit keys from 0 to 9, as well as the validation and cancellation keys, when these keys are located themselves on the periphery, and not in the center, of the screen. touch.
- the virtual keyboard shown on the touch screen has buttons on the periphery and in the center of the touch screen, ten markers make it possible to materialize the borders between the keys of digits from 0 to 9, as well as the keys of validation and cancellation.
- the marker materializes the middle of one side of said touch screen, and therefore, if one considers advantageously a mark for the middle of each of the four sides of the screen (in the case of a rectangular screen or square), then the outline of the touch screen itself is spotted.
- the touch screen represents a virtual keyboard
- the user knowing the predefined organization of the keys on the touch screen, can deduce the location of each of the keys by identifying the media, and therefore the sides of the screen. the touch screen, and therefore the touch screen itself.
- four marks may suffice, for example points, or short lines perpendicular to the sides of the screen.
- the mark materializes a corner of said touch screen, and therefore, if one advantageously considers a mark for each of the four corners of the screen (in the case of a rectangular or square screen), then the outline of the touch screen itself is spotted.
- the touch screen represents a virtual keyboard
- the user knowing the predefined organization of the keys on the touch screen, can deduce the location of each of the keys by identifying the corners, and therefore the contours of the touch screen itself.
- four marks are necessary, for example points, or short lines, or any other form.
- the registration area is located along at least one edge of said touch screen.
- This embodiment makes it possible to identify for example different keys of the touch screen by placing different markers along at least one edge of the touch screen, or even around the touch screen. In this way, the marks are close to the corresponding keys of the touch zone, or vis-à-vis these keys, and offer satisfactory ergonomics to the user.
- the registration information corresponds to a mark materializing the width of a virtual touch of the touch screen.
- the mark corresponds to a rough band corresponding to the width of a virtual key.
- alternating rough strips and smooth areas can be provided to materialize the adjacent key widths.
- the marking zone is located outside of the touch screen and obtained by a technique belonging to the group comprising:
- the registration is advantageously without touching the touch screen because the cue area is located outside the touch screen. In this way, the user is not likely to inadvertently activate an application, or enter incorrect information via the touch screen.
- the user first locates, via the registration information, a key he wants to activate and then moves his finger (or a stylus) on the touch screen, to activate the key marked.
- This offset of his finger, or a stylus is done according to a predetermined criterion.
- the user knows the configuration of the keys represented on the touch screen and knows that when he sees the number "1" for example, the key of the corresponding touch screen is on the right of the marker, whereas when for example, the key of the corresponding touch screen is below the mark, or when it sees the number "8" for example, the key of the corresponding touch screen is to the left of the mark .
- the registration information protrude above the surface of the device.
- the marks appear in hollow below the surface of the terminal.
- the registration area is obtained by a coating technique with an optical varnish of the surface of the touch screen of the device.
- the registration information corresponds to a mark materializing a predetermined key, for example the number key "5", of the touch screen.
- the marking areas are located on at least one side of the device.
- the relief marks are for example located on one of the sides / slices of the device, or on a surface not parallel to the surface of the touch screen.
- the registration information corresponds to a braille representation of at least one virtual touch of the touch screen.
- This embodiment provides for identifying the keys using their braille representation, thus allowing the user to read directly the key via the registration area.
- this embodiment makes it possible to represent the digit keys from 0 to 9, as well as the validation, correction or cancellation keys.

- FIGS. 4a and 4b illustrate an example of registration zones according to a third embodiment of the invention
- FIGS. 5a and 5b illustrate an example of registration zones according to a fourth embodiment of the invention
- Figure 6 shows the main steps of the method of using a device according to one embodiment of the invention.
- the general principle of the invention is based on the embossing, on a portable device comprising a touch screen, of one or more areas carrying registration information (s), called tracking areas, allowing in particular a non-user.
- a portable device comprising a touch screen, of one or more areas carrying registration information (s), called tracking areas, allowing in particular a non-user.
- - LED to locate one or more corresponding areas of the touch screen.
- a blind user who wishes to activate a particular area of the touch screen first slides his finger on the device to detect the registration information in relief until reaching the information identifying the particular area in question. It then moves its finger to the touch screen, according to predetermined criteria detailed below, to activate the particular area chosen on the touch screen.
- the marking areas can be located anywhere in the device.
- these identification areas are located "outside" of the touch screen, so that the user is not likely to inadvertently activate an application, or enter incorrect information via the touch screen, then it seeks to detect the registration information according to the invention.
- a registration information may correspond to a relief mark, located in front of a touch of the touch screen, so that it can locate this key on the screen.
- a user can detect the registration information by sliding his finger on the different registration areas, then activate the desired keys by deporting his finger to the touch screen, vis-à-vis the information of detected location.
- the user it is also possible for the user to detect the registration information, located at the edge of the touch screen, while voluntarily passing his finger. on the touch screen, waiting for a sound signal emitted by the device each time it passes over a predefined region of the touch screen (for example an intermediate zone between two keys).
- a predefined region of the touch screen for example an intermediate zone between two keys.
- the activation of a particular area of the touch screen is subject to additional action by the user (for example, a double-click, or a specific key press), so as to what the passage of his finger on the screen is not interpreted as the voluntary activation of this particular area of the touch screen.
- the user knows the exact configuration of the registration information on the device as well as the exact configuration represented on the touch screen, or that it is guided by a hearing aid provided by the device (for example, an audible message indicates the configuration of the keys, or simply indicates that the key configuration is "classic", etc.).
- the touch screen is divided into a number of separate areas, which he knows the functions.
- the location information is around the touch screen, vis-à-vis each of the separate areas.
- the user can easily locate these areas of the touch screen, from its detection of the registration information.
- the touch screen represents a virtual keyboard configured as illustrated in FIGS. 1a and 1b
- the user knows that when he locates the number "1" for example, the touch of the corresponding touch screen is to the right of the mark, whereas when it marks the number "2", the key of the corresponding touch screen is below the mark, or when it marks the number "6", the corresponding touch screen key is to the left of the marker.
- the user does not know a priori the exact configuration of the tracking information on the device and the exact configuration shown on the touch screen.
- he must "test" the different areas around the registration information, in order to deduce the direction to which he must deport his finger, or his stylus, to activate the corresponding area of the screen touch.
- the "test" of the different zones consists of moving his finger a few millimeters to the right, above, to the left and below the embossing information, so as to deduce where the touch screen is located. relative to the registration information.
- the same registration information can be repeated in two distinct registration areas, in order to better guide the user.
- the registration information 11 1 of the digit "1" is present on the left and above the virtual key "1".
- the registration information of the digit "3" is also present twice, above and to the right of the virtual key "3".
- FIGS. 1a and 1b An example of a device according to the invention corresponding to an electronic payment terminal 1, as illustrated in FIGS. 1a and 1b, comprising a touch screen 10 and, according to various embodiments, locating zones 11 which can carry different registration information 113, 116.
- the general principle of the invention is also based on the fact that, for security reasons, the display of the touch screen is inactivated when the device is used by a blind user. This inactivation is illustrated in FIG. 1b by the virtual keys of the touch screen in gray and their dashed outlines.
- the blind user does not need the display of the touch screen since it benefits from the registration areas according to the invention, the use of the device has enhanced security by disrupting the observation of 'an ill-intentioned person who, by looking at what the blind user enters without his being aware of it, could deduce his PIN code for example. Indeed, if the virtual keys are not displayed, an observer can hardly identify which keys have been activated.
- the ergonomics of a device according to the invention is reinforced by the presence, apart from the touch screen, some keys of a keyboard in a standard form, that is to say non-touch.
- This configuration makes it possible to reduce the number of virtual keys on the touch screen, and therefore also the number of necessary registration areas, while allowing a non-sighted user to find a more traditional configuration with standard keys.
- the keys outside the touch screen are the "enter” function keys to validate, “cancel” to cancel and “correction” to correct.
- FIGS. 2a to 2c Two variants of a first embodiment of the invention will now be presented with reference to FIGS. 2a to 2c.
- this registration information corresponds to braille representations of the keys of the virtual keyboard represented on the touch screen.
- FIG. 2a illustrates a first variant in which the touch screen represents a virtual keyboard in a so-called "classic" configuration.
- This variant in particular allows the user to refer to a more familiar layout of the keys.
- this variant also allows complete compatibility between the use of the invention by a blind user and the use of the invention by a user who is not visually impaired.
- Figures 2b and 2c respectively illustrate a second and a third variants, wherein the touch screen is a keyboard "adapted" for use for blind users. These two keyboard configurations vary by the position of the keys, and also the number of keys represented.
- the configuration of the virtual keyboard can then for example be activated by an oral response, requiring voice recognition, or by the activation of a key (requiring the presence of a person other than the user when the latter is blind).
- the electronic payment terminal has a registration area in view of some keys of the virtual keyboard, in this case all the keys except the central keys.
- twelve registration areas 22 carrying twelve different registration information (227, 223, 226, ...) allow a blind user to locate all the keys of the virtual keyboard.
- the keys on the periphery of the touch screen can be located “directly” via the identification information in vis-à-vis, and the central keys can be located by "deduction” and / or using a touch mark directly present on certain areas of the screen, for example the presence of a raised dot to locate and identify the key "5" (see the description of the fifth embodiment).
- the keys corresponding to the numbers 1, 2, 3, 4, 6, 7 and 9 are identified by means of separate registration information, each corresponding to the respective braille representation of said digits.
- the "Correction”, “Cancellation” and “Validation” keys are identified by separate registration information, corresponding to the Braille representation of their respective English abbreviations, namely "COR”, “CAN” and “ENT”.
- the key “. Is identified by a tracking information corresponding to the Braille representation of "DOT" (for "point” in English) and the "Function” key is identified by a tracking information corresponding to the braille representation of its abbreviation " FUN ".
- the blind user it is preferable for the blind user to know the configuration of the keys of the virtual keyboard, in particular so as to be able to deduce the central keys 5, 8 and 0, from the other keys identified according to this variant of the 'invention.
- the electronic payment terminal has a registration area opposite each of the keys of the virtual keyboard, these being organized on the periphery of the touch screen (that is to say, in a configuration adapted to blind people).
- the third variant of this embodiment is identical to the second variant described above and further provides a region 23 for a different use of the registration areas and the virtual keyboard.
- the electronic payment terminal has an intermediate zone between two keys of the virtual keyboard, for example the region 23 illustrated in Figure 2c (in bold).
- the region 23 illustrated in Figure 2c in bold.
- this third variant requires a different technique of activation of the keys, by an additional action of the user, in addition to pressing the key considered.
- the user necessarily makes a pressure on the touch screen to navigate the screen.
- the user must therefore perform an additional action when he wishes to validate the activation of a key he has pressed.
- this additional action of the user can be a "double press" on the key in question, or a specific key press (not shown), which could be located for example in the center of the virtual keyboard.
- FIGS. 3a and 3b Three variants of a second embodiment of the invention are now presented with reference to FIGS. 3a and 3b.
- this registration information corresponds to marks, for example short lines, located around the touch screen perpendicular to its edges, between each of the keys of the virtual keyboard.
- the registration information materializes the boundaries between the keys of the virtual keyboard.
- FIG. 3a illustrates a first variant in which the touch screen represents a virtual keyboard in a so-called "conventional" configuration
- FIG. 3b illustrates a second variant, in which the touch screen represents a Keyboard suitable for use for blind users.
- a user knowing the configuration of the virtual keyboard, can locate each of the keys by detecting, via the registration information, the boundaries between each of them.
- FIGS. 4a and 4b Two variants of a third embodiment of the invention are now presented in connection with FIGS. 4a and 4b.
- this registration information corresponds to marks, for example short lines, located around the touch screen, perpendicular to the middle of each side of the touch screen.
- the registration information materializes the backgrounds of the sides of the virtual keyboard.
- This embodiment has, as the previous, the advantage of requiring a less important registration than the first embodiment, the pins used here being all identical and simpler to achieve than Braille representations.
- the number of pins required is less than that of the previous embodiment.
- a user knowing the configuration of the virtual keyboard, can locate each of the keys by detecting, via the registration information, the media of each of the four sides.
- This fourth embodiment is close to the previous one, except that the registration information corresponds to marks embodying the corners of the virtual keyboard.
- the markers form angles located outside the corners of the touch screen, as shown in bold in FIGS. 5a and 5b, or else short lines positioned diagonally outside the corners of the touch screen. as shown in dashed lines in FIGS. 5a and 5b.
- the necessary reference number is even smaller than for the other embodiments, but nevertheless requires a good knowledge of the configuration of the keyboard by the user, especially for the first variant.
- this variant illustrated in FIG. 5a in which the touch screen represents a virtual keyboard of "classical" configuration, five keys separate two marks in the direction of the height of the keyboard, and three keys separate two marks in the direction of the width, making a little more complex the location of each of the keys between each mark.
- the central keys are also harder to locate by deduction.
- the location or zones are located on the surface of the touch screen, for example by applying an optical varnish, which makes it possible not to disturb the touch operation of the screen, while allowing to materialize for example one or more keys on the touch screen directly.
- the invention allows for example to materialize the key "5", as on a standard keyboard. Any other type of tracking information may be considered.
- this embodiment like the previous one, requires a different technique of activation of the keys, by an additional action of the user, in addition to pressing the key considered.
- the user necessarily makes a pressure on the touch screen to detect the mark or marks located on the surface of the touch screen. As indicated above, the user must therefore perform an additional action when he wishes to validate the activation of a key he has pressed.
- this embodiment of the device requires a different technique of activation of the keys, by an additional action of the user, in addition to pressing the key considered.
- the user necessarily makes a pressure on the touch screen to detect that it passes in a zone between two keys, and this should not be interpreted as the activation of each of the keys pressed successively. The user must therefore perform an additional action when he wishes to validate the activation of a key he has pressed.
- the blind user slides his finger on a particular region (denoted 23 and illustrated in bold around the touch screen in FIG. 2c), "on horseback".
- a particular region denoted 23 and illustrated in bold around the touch screen in FIG. 2c
- On the registration information and the touch screen for detecting the registration information according to the invention and on an intermediate zone situated between two keys of the virtual keyboard.
- This pressure 60 of his finger on the intermediate zone also generates a successive pressure on two successive keys of the touch screen.
- the user thus slides his finger on this particular region until he has detected, during a detection step 61 of the desired key, the registration information corresponding to a touch of the touch screen that he wants to activate.
- he has detected this registration information he has therefore pressed the key he wishes to activate, and must implement an additional action 62 to validate the activation of the key pressed.
- this extra action can be a "double support" on the considered key, or pressing a specific specific key, for example located in the center of the virtual keyboard.
