    The invention relates to a method for making user inputs in electronic devices using a touch-sensitive input surface, wherein the touch-sensitive input surface comprises a virtual keyboard with a plurality of keys, wherein each key of the keyboard is associated with a surface area of the input surface, wherein the surface of the virtual keyboard is smaller than the area of the touch-sensitive input surface.
    The invention further relates to an input element for electronic devices, in particular for carrying out the method according to the invention, comprising a touch-sensitive input surface, a sensor device for detecting the position of a touch of the input surface and optionally an actuating force and electronic processing means to which the position and possibly force data of Sensor device are supplied and which are adapted to provide on the input surface, a virtual keyboard with a plurality of keys, wherein each key of the keyboard is assigned a surface area of the input surface, wherein the area of the virtual keyboard is smaller than the area of the touch-sensitive input surface.
    Input elements having a touch-sensitive input surface are widely used and used in a variety of electronic devices to make user inputs. In the context of the invention, the input element may be designed, for example, as a touch-sensitive electronic display device (touchscreen). A touch screen is a combined input and output device, namely a combination of an electronic display device, such as an LCD display, with a touch sensor in which the program flow of a technical device, usually a computer, can be controlled directly by touching parts of an image , The input element can also be a touchpad of a technical device.
    Touch-sensitive input surfaces may be provided with haptic feedback elements to give the user haptic feedback, in particular depending on the position of the touch and / or in response to the user input. For the purpose of haptic feedback, the contact surface of the touchscreen or touchpad can be translationally movable, wherein the translatory movement can be controlled by means of an actuator. The actuation of the actuator can be done in response to user input, for example, to confirm a user input. Such haptic feedback facilitates the operation of a technical device by means of touchscreen or touchpad.
    In the context of the invention, a virtual keyboard is understood as a hardware or software-technically implemented assignment of surface areas of the touch-sensitive surface to predetermined or dynamically assigned user inputs, each area forming a virtual key. The areas representing the individual keys are in a manner known to the user, e.g. arranged in a grid. The surface areas are arranged in particular adjacent to each other, wherein the sum of the keys a delimited
    Area of the input surface. In the case of touch screens, this is referred to as an on-screen keyboard, which is usually displayed as an application window that can be operated by touch, whereby the individual keys are visually displayed.
    As a help to rewrite conventional mechanical computer keyboards usually have two haptic marks on the keys of the letters F and J and a mark for the center of the ten-key numeric keypad on the key for the number 5. These are tactile surveys in the form of a dot or a stroke, or a tactile deviating shaping of the keys. These facilitate finding the keys and are therefore referred to as orientation keys.
    In the case of user input by means of touch-sensitive surfaces, e.g. Touch screens or touchpads, orientation keys can not be easily realized, so blind entry is not possible. This problem is particularly serious for visually impaired persons.
    The present invention therefore aims to improve a method and an input element of the type mentioned in that the operation of a virtual keyboard is also made possible for visually impaired persons.
    To solve this problem, the invention essentially provides the following steps in a method of the type mentioned in the introduction:
    Making a first touch of the input surface at a first position, automatically defining the position of the virtual keyboard on the input surface so that a predefined orientation key of the keyboard is located on the area of the first position, touching the input surface at a second position in one of a key assigned surface area lies,
    Pressing the key, whereby a user input is made.
    The invention is thus based on the idea of defining the orientation key by the position of the first touch, i. set the orientation key to the first touch position and align the virtual keyboard with the orientation key. The arrangement of the keys and the user inputs assigned to the keys, in particular numbers and / or letters, are known to the user just as well as the predetermined positioning of the orientation key within the keyboard. The blind user knows that the orientation key lies in the place of the first touch and can now access the position of the remaining keys knowing the key arrangement. In particular, the user knows the relative position of the desired keys relative to the orientation key and can therefore touch the input surface without visual control in one of the respectively desired key area associated and press the key. The user can operate a plurality of keys one after the other in the same way. The orientation key itself can preferably also be designed as a key to be actuated and with a predetermined
    User input be occupied. Alternatively, the orientation key can only be used with one
    Orientation function and do not act as a key itself.
    The positioning of the orientation key within the keypad or the keyboard is irrelevant as long as the user knows the positioning. Advantageously, the orientation key is formed on a key which also serves as an orientation key in mechanical keyboards. Preferably, it is provided that the keyboard is formed as a numeric keypad comprising keys for the numbers 0 to 9 and the key for the number 5 forms the orientation key, the key for the number 5 is preferably arranged in the middle of the numeric keypad.
    A particularly advantageous operation results according to a preferred procedure, when the contact of the input surface between the first position and the second position is maintained. After the initial touch of the input surface, the user's finger or stylus or the like is left on the input surface and moved laterally to the desired key. Thus, the position of the desired button can be found in a simple manner, it is preferably provided that the reaching of the second position is signaled by a haptic feedback of the input surface, in particular a deflection of the input surface.
    Once the desired key has been found in this manner, the key may be actuated, wherein the actuation of the key preferably comprises exerting an increased pressure on the input surface, in particular a deflection of the input surface.
    According to a preferred procedure, the actuation force is measured and the actuation is triggered when a predetermined threshold value of the actuation force is exceeded.
    After a key has been pressed, the user can continue with the finger or the stylus on the input surface and make another key actuation at the position of another key. Between two consecutive key presses, the finger or stylus can also be raised for a short time. In a renewed initial touch of the input surface, the position of the orientation key is preferably redefined and the keyboard in turn on the
    Orientation key aligned. The input process can be continued in the sequence as described above.
    When the finger or stylus is raised for an extended period of time exceeding a predetermined period of time, the previous input is preferably erased and a new input operation can begin. Advantageously, the erasure of the input is made recognizable to the user by an acoustic signal emitted by the electronic device.
    At the end of an input process, the input can preferably be acknowledged by pressing a confirmation key. Alternatively, the end of the input process can be automatically detected, e.g. as soon as a given
    Number of characters has been entered, e.g. after entering four digits. Advantageously, the end of the input process is made recognizable by an acoustic signal emitted by the electronic device.
    Preferably, it is further provided that the recognition of the first touch is signaled by a haptic feedback of the input surface, in particular a deflection of the input surface, wherein the haptic feedback for the detection of the first touch and the haptic feedback for detecting the second position are preferably different from each other. Alternatively, the detection of the first touch can be mediated by an acoustic signal.
    According to a further aspect, in an input element of the type initially mentioned, the invention essentially provides that the sensor device is designed to detect a first contact of the input surface at a first position and to supply the position data of the first contact to the processing means, where the position data is used for the first contact in order to define a position of the virtual keyboard on the input surface such that a predefined orientation key of the keyboard is arranged on the area of the first position, that the sensor device is further adapted to detect a touch of the input surface at a second position and the the second position corresponding position data to the processing means, and that the processing means are adapted to compare the position data of the second position with the button associated with a surface area of the keyboard and register the actuation of the key when the second position is in the area associated with the key.
    For carrying out the above-described preferred embodiments of the method according to the invention, the input element can be developed as follows.
    A preferred embodiment provides that the input surface is assigned an actuator in order to effect a haptic feedback, in particular a deflection of the input surface, on the input surface, the actuator preferably being drivable by the processing means.
    A further preferred embodiment provides that the processing means interact with the actuator in order to signal the reaching of the second position by a haptic feedback on the input surface, in particular a deflection of the input surface.
    A further preferred embodiment provides that the actuation of the key is registered when the second position lies in the area assigned to the key and the actuating force exceeds a predetermined threshold value.
    A further preferred embodiment provides that the processing means interact with the actuator in order to signal the detection of the first touch by a haptic feedback on the input surface, in particular a deflection of the input surface.
    A further preferred embodiment provides that the haptic feedback for the detection of the first touch and the haptic feedback for the detection of the second position are preferably different from each other.
    A further preferred embodiment provides that the keyboard is formed as a numeric keypad comprising keys for the numbers 0 to 9 and the key for the digit 5 forms the orientation key.
    Processing means in the sense of the present invention may be embodied as hardware and / or software, in particular one, preferably with a memory and / or bus system and with the touch-sensitive surface or its associated sensor device. have signal-connected, in particular digital, processing, in particular microprocessor unit (CPU) and / or one or more programs or program modules. The CPU may be configured to process instructions implemented as a program stored in a memory system, to acquire input signals from the touch-sensitive surface or its associated sensor device, and / or to output signals to a data bus and possibly to a touch-sensitive surface Display unit. A storage system may comprise one or more, in particular different, storage media, in particular optical, magnetic, solid state and / or other non-volatile media. The program may be arranged to be capable of embodying the method described herein so that the CPU may perform the steps of the method.
    In order to realize the described haptic feedback, any haptic feedback element can be used which is suitable for setting the touch-sensitive input surface in motion. An input element which is provided with a haptic feedback element is described, for example, in WO 2010/080917 A1. The actuator for driving the translational movement of the contact surface is formed in the embodiment described in WO 2010/080917 Al as an electrostatic parallel plate actuator. An electrostatic parallel plate actuator comprises two electrode plates which are held at a variable normal distance from each other. The one electrode plate is rigidly arranged relative to a housing or the like of the electronic device. The other, cooperating with the contact surface electrode plate is deflected against the force of a return element.
    Between the two electrode plates, a gap is provided, in which a dielectric is arranged. Now, when a voltage is applied to the electrode plates, electrostatic forces arise, which act in the sense of repulsion or attraction of the electrode plates and cause a corresponding deflection of the electrode plate held movably. The return element ensures the return of the movably held electrode plate to its original position.
    When pressure is applied to the input surface or the haptic feedback element, an air gap between the electrode plates is substantially reduced, whereby the total capacity of the capacitor formed by the electrode plates increases. As a result, it succeeds in measuring the compressive force exerted on the input surface and in
    Depending on the pressure force if necessary to produce a haptic feedback. In particular, when a settable setpoint value is reached, a high-voltage pulse can be applied which generates a force pulse, which i.a. depends on the electrode area and the voltage amplitude.
    However, the measurement of the force applied to the input surface may also be by other sensor mechanisms, e.g. by inductive or resistive working sensors.
    In order to effect an automatic reset of the actuator as soon as the voltage pulse applied to the electrode plates is over, it is preferably provided that the at least one electrode plate can be deflected against the force of a restoring element. The return element may be formed, for example, as a spring element.
    The control of the parallel plate actuator can in principle be arbitrary, wherein depending on user input any haptic feedback profiles can be realized. A feedback profile usually comprises a sequence of several deflection movements of the contact surface with a predetermined signal shape, defined by flank, pulse duration and amplitude.
    The invention will be explained in more detail with reference to an embodiment schematically illustrated in the drawing. 1 shows an input element embodied as a touch screen with the virtual keyboard in a first position, and FIG. 2 shows the touch screen according to FIG. 1 with the virtual keyboard in a second position.
    The input element shown in the embodiment can in principle be implemented in any electronic device in which a user input is provided by means of a virtual keyboard. For example, the operation of machines with touch display, especially cash dispensers is becoming increasingly complex. This is driven by the increasing functionality of the machines, for example the possibility of recharging credits on chip cards, the purchase of credits for the mobile phone, but also of the technology. This complicates the operation for visually impaired and blind as well as elderly people, so that today they are hardly able to use such devices. Although there are devices that are equipped with an acoustic operating aid for visually impaired persons, this accessibility is often insufficient in view of the increasing complexity of the devices.
    This is the case in particular with touch-guided surfaces, which are increasingly being used due to the trend dictated by the consumer industry. Touch-guided surfaces have the great advantage that the Seifservice terminals can be used more universally and thus, for example, can also be used for advertising or other services. On the other hand, the operation of these applications is difficult for physically disabled or elderly persons, as they are often unfamiliar with the operation of these devices or the operation is not designed for the needs of these people.
    In conventional devices, the PIN input is via a physical numeric keypad, whereby the operation is facilitated for visually impaired persons, that the
    Button "5" is marked by a small increase and can be felt in this way by the user.From there, the corresponding button is searched for and pressed by pressing.
    Due to the omission of the numeric keypad in devices, especially cash dispensers with touch-sensitive input surface, especially touch screens, alternative input methods for PIN entry by the blind and impaired persons are therefore required.
    FIG. 1 shows an input unit of a device, in particular a cash dispenser, with a touch screen 1. The touch screen 1 has a touch-sensitive input surface 2. The touch screen controlling processing unit is designed here to a defined user input, for example, individual areas of the input surface 2, e.g. a letter, a number or a program command to allocate, these areas are displayed on the touch screen accordingly as input fields. When the user touches the input field, the associated user input is made and recognized as such by the processing unit. In the case of a virtual keyboard 3 designed as a numeric keypad, a plurality of input fields or keys 4 are arranged like a grid.
    The position of the virtual keyboard 3 within the input surface 2 is not fixed in the context of the present invention, but is based on the position of the first touch of the input surface 2 by the user. In the example according to FIG. 1, the position of the first contact is denoted by 5. The processing unit of the input unit is adapted to receive the position of the first touch and to define the position of the keyboard 3 within the input surface 2 so that the position of the first touch always coincides with the key 6 formed as an orientation key for the digit "5" Regarding the required area for the arrangement of the keyboard 3, a valid first contact must take place within the area designated by 7. Initial contacts taking place outside this area 7 are signaled with an acoustic error message.
    If the first touch occurs within range 7, it is considered valid and can be acknowledged by an audible or haptic feedback. Starting from the position of the first touch, which always corresponds to the key for the number "5", the user can now move his finger to the desired key.When the finger reaches the area of a key, this can be signaled by a haptic feedback can now actuate the key reached by exerting an increased pressure on the user interface 2. The increased pressure is registered, for example, by means of a force measurement.
    After the finger is lifted, the touch is touched again as a first touch and used to define the position of the orientation key "5." The next key is then pressed as described above.
    With reference to FIG. 2 it can be seen that the position of the keyboard 3 depends on the position of the first contact 5.
    If the finger is lifted for a long time, the entry is preferably canceled and the process restarts.
