Method and device for contact-free entry of characters

The invention relates to a method for contact-free entry of characters, in particular alphanumeric characters, as well as a method performing device and their use.

In particular, the invention relates to a method and a device in which the characters, as input to a vehicle-installed user system, in particular navigation system, communication system, entertainment system, tachograph, in particular with electronic logbook, tachograph and / or comfort system, in particular for air conditioning or seats transfers.

Typically, the input of characters manually via keyboards or keypads, as input devices for z. Occurs As computers are configured or user devices such. As navigation devices and the like are integrated. The known keyboards are often equipped with mechanical buttons, but can also, for example, with a touch-sensitive input field (so-called

Touchpad) be equipped. It is also known to configure screens with touch-sensitive surfaces as so-called touch screens where the user can make typing on the screen itself. In addition to entering each character also handwritten entries can be made that are recognized as a graphic logo and processed here.

In these known methods and devices JE the input is always by touching respective buttons or sensitive touch surfaces. This requires the user a certain manual dexterity and brings problems such as pollution and mechanical wear of the input device itself. There is also the look on keyboard or control panel, the problem of diversion of the user, especially while driving in a vehicle.

In DE 103 12 812 A 1 such a device is described, for example as a combined display and input device for motor vehicles. This has a designed as a handwriting input surface area of ​​the screen on which the user can enter data, which are recognized by a handwriting recognition module as a handwritten input made and processed. Again, it is necessary for the user to touch the screen as a touch screen trained.

In DE 102 11 307 Al a method and an apparatus for opto-electronic detection of the movement or position of an object, for example. As the finger of one hand, pre- sented. Here is one key by opto-electric

Components (transmitting element and receiving element) so reproduced that the operation of the key can be carried out without contact. Thus, an opto-electric keyboard is formed, which can replace a mechanical keyboard. The solution is used in particular for non-contact local input individual characters. There is also the possibility of handwriting recognition is mentioned without going into detail but this. It would be desirable, however, to have a solution for non-contact input of characters in any form.

Other known methods and apparatus for non-contact input are ( "gestures" so-called) is known only in connection with the input of commands and for the detection of gestures in order to compile a user-side control of systems and devices. For example, in the DE 20 2006 001 037 Ul a device in the form of an electrical circuit arrangement for the generation of signal events described which has for generating an input event and a switching signal via an input component that detects by means of sensors without contact field electrical interaction effects with hand or finger of a person, and without contact or from the position . movement of the hand or of the finger recognizes. Furthermore modulated signals over the person's body can be transmitted to the input component, for example, to identify the person on the basis of the modulated signal. However, the solution described herein is ledi possible for the user side control performed by systems or equipment, such. As the seat, mirrors, and steering wheel configuration in a vehicle. By entering the characters, in particular alphanumeric characters, nothing is described therein.

It is therefore an object of the present invention to overcome the problems of the known solutions mentioned above in an advantageous manner. In particular, to a method and apparatus for non-contact inputting characters, in particular alphanumeric characters, are proposed that can be implemented in a particularly user-friendly. Moreover, very practical uses for the device to be proposed.

The object is achieved by a method having the features of claim 1 and by an after-working apparatus with the features of the independent claim, as well as their use proposed here.

Accordingly, a method is proposed in which by means of a plurality of spaced sensors the position and movement of hand or finger of a person in the form of position data detected, in which are computed for a write track by means of evaluation of the position data write trace data to the movement of the hand or of the finger corresponds, and wherein the trace data is converted by means of a handwriting recognition into corresponding characters. Under Characters and signs and symbols are understood here as defined by the user and the system have been trained. Accordingly The proposed device comprises a sensor unit connected to a plurality of spaced sensors, detects the position and movement of the hand or finger of a person in the form of position data, and having an evaluation unit connected thereto, which calculates from the position data writing track data, and a so having associated detection unit that the trace data by means of a

Handwriting recognition in corresponding character changing. It can therefore be carried out a general as well as individual handwriting recognition.

In particular, the invention is also based on the realization that a combination of a plurality of sensors equipped with sensor sign with an intelligent handwriting recognition, in particular in the form of such a device, particularly suitable for non-contact input of font may be used. This may in particular be realized in a vehicle-installed user system, such as in a navigation system, communication system, entertainment system, tachograph, in particular with electronic logbook, tachograph and / or Komfortsys- system, in particular for air conditioning or seat adjustment.

The invention provides an equipped with a plurality of spaced sensors sensor with an intelligent handwriting recognition is com- bined, so that a contact-free entry of characters can be realized in very user friendly way in an advantageous manner. To enter the user need only lead his hand or finger in the sensor so that it almost easy and can write without difficulty "in the air".

the position data is preferably continuously detected to calculate the trace data, the position data will be evaluated at least one position, to assign all of the position data detected and / or the trace data to a virtual write area and / or a person. In this way, by means of the sensor not only a continued ongoing recognition of the position and the actual tracking of the hand or finger to obtain the desired trace data but also a mapping of the trace data to a virtual writing area and / or a person. In this context z. B. means min- least each of which is associated with the virtual writing area and / or the person two, preferably four, sensors, defining a sensor array. In particular, at least two different sensor fields can be defined for this purpose, which are each associated with a virtual writing area and / or a person.

Thus, with such a breakdown of the sensors in different sensor fields a very simple to realize assignment of the trace data obtained is achieved, so that these data (area relative z. B., function-related and / or individual) selectively can be further processed. If the sensors, for example, installed in a vehicle, it can be easily recognized in this way, whether the handwritten non-contact input is as on the driver's side or the passenger side. Thus, the trace data obtained can then immediately the person in question, ie the driver or the passenger, are assigned. Preferably, the trace data is then processed by means of such handwriting recognition, which could have been trained on this person back. It can also be recognized individually defined characters and symbols. Likewise, the processing can be done function related by z. As it is recognized that the input near the display of the navigation system was such that the input automatically to the corresponding functions such. As the destination input can be assigned. As sensors, for example, electro-optical, acoustic, inductive and / capacitive sensors can be used. In the use of capacitive sensors is preferably transmitted a modulier- TES signal through the body of the person to the hand or the finger back, that the advantage there changes in the sensor field prevailing electric field strength or manipulated, which signal by means of the capacitive sensors detek- becomes. Thus, it is possible to receive in addition to the spatial detection of the hand position or movement on the sensor and a modulated information signal which represents, for example, information about the person himself.

Preferably, the method and apparatus for an installed in a vehicle user system be used, particularly in navigation systems, communication systems, entertainment systems, recording equipment, in particular with e- lektronischen logbook, tachograph and / or comfort systems, in particular for air conditioning or seat adjustment.

These and other advantages arise from the dependent claims.

In the following the invention is described in detail based on exemplary embodiments and with reference to the accompanying figures in which:

Fig. 1 is a block diagram of a device according to the invention;

Fig. 2 illustrates a breakdown of the sensors in different sensor fields;

Fig. 3, an additional transmission of a modulated Sig- Nals is over the person's body; Fig. 4 is a flow chart for an inventive method.

Fig. 1 shows an arrangement with an inventive device having the non-contact input characters from a sensor unit 20 that detects using a plurality of spaced sensors 21, the position and movement of a hand 40 or a finger in the form of position data PD. The apparatus further comprises means connected to the sensor unit 20 evaluation unit 50, which calculates from the position data PD trace data SD for a trace, which corresponds to the movement of the hand 40th In addition, the device has means connected to the evaluation unit 50 detection unit 31 which converts the trace data SD into corresponding character using a handwriting recognition (Z).

The recognition unit 31 is integrated in this example, in an application system 30 which is embodied here as a navigation system. The navigation system 30 includes in particular an application module 32, 31, the obtained character Z receives from the handwriting recognition and processed as input data. Thus, from the detected hand or finger movement, the handwritten lent by the user and non-contact input characters Z are detected, ie for. As alphanumeric characters A, B, C, ... and numbers 0, 1, 2, ..., etc. The processing performed by the sensor circuit 20 detecting the position and movement of the hand 40 such can. For example, be carried out by known methods which have been already initially mentioned. The continuous detection of the changing position data PD is carried away over a predetermined period of time to detect the movement of the hand and to detect a Schreibzug thereof. Which is made in the recognition unit 50 calculating the trace data SD can also be done by conventional methods as mentioned at the outset. The recognition unit may also be external and separately implemented from the application module, which then communicate with each other via a suitable interface in connection.

It is now the invention in particular also on the realization that a combination of a plurality of sensors equipped with sensor with an intelligent handwriting recognition, in particular in the form of so-equipped apparatus can be particularly well used for non-contact input of characters. When application area, in particular, installed in a vehicle user systems, such as navigation systems, communication systems, entertainment systems, tachographs and / or tachograph and comfort systems are suitable.

Preferably, an assignment of the trace data SD is now performed on a virtual writing surface or a person by means of the presented device. This will ben described in more detail below with reference to FIGS. 2 to 4. It also describes in more detail below, that over the person's body, particularly over the hand 40, modulated signals can be transmitted to the sensor unit 20 to pass additional information to the application module 32nd The required modules or com- ponents are in the Fig. 1 in the form of a signal transmitter 11 and signal receiver 22 is shown, wherein the signal transmitter 11 may be integrated, for example in a vehicle seat 10. Also, these and further aspects of the invention will be described in more detail below.

Fig. 2 shows the arrangement of a plurality of sensors which are arranged, for example in a vehicle so as to form a first sensor array 23 'and a second sensor array 23' 'and define. In the illustrated example, the sensor 23 comprises a total of six mutually spatially beabstan- finished detectors 21A to 21F, the sensors 21A, 21B, 21D and 21E, a rectangular first sensor array 23 'span. This first sensor array 23 'is to the left in a vehicle in the vicinity of a first person P' which is represented for example by the driver. The second sensor array 23 '' is defined by the sensors 21B, 21C, 21E and 21F on the right side of the vehicle and a second person P 'which is represented for example by the passenger or passengers' assigned. a hand now is to the left in the first sensor field 23 belonging hand ', this as a person to the first P' detected. A 23 'in the other, left sensor field' detected hand is again the second person P 'associated'.

This allows already advertising carried out an assignment or identification of the person by the sensor 23 itself to, which makes the entry. In each sensor box 23 'or 23' 'may also include a virtual writing surface 24' and 24 '' are defined, each of which represents the permissible for the input area. Outside the writing surfaces no entries are permitted. The sensors may for example be arranged so that the corresponding write surfaces 24 'and 24' 'are in close proximity to an operating device, in particular to a local display screen or display, aligned. Thus, the respective virtual writing surface is located above a respective BiId- screen surface or operating device, whereby an input through display of possible auxiliary symbols and the like can be facilitated. A direct and contact-free user experience is possible.

The sensor system 23 illustrated here in Fig. 2 preferably comprises electro-optical detectors 21A to 21F, the spatially distributed selectively are arranged in the vehicle and a plurality of sensor fields 23 ', 23' ', ... and a plurality of virtual writing surfaces 24', 24 define '', .... It can also have multiple virtual writing surface, a sensor field to allow further differentiation. It is hereinafter referred to an example of a method for non-contact input described which can be performed with the embodiment shown in the Fig. 1 apparatus and in the FIG. 2 arrangement shown, in which case chart also to the drain of FIG. 4, reference is made :

For example, the sensors 21A, 21B, 21D and 21E detect in a first step 110, that a hand on the left virtual writing surface 24 'is located. Then, a continuous detection of the position or movement of the hand or finger is performed continuously, the position data PD (see also Figure 1.) To be detected. In a subsequent step 120, the trace data SD are calculated from the obtained position data corresponding to the movement of the hand or of the finger. Then, in a subsequent step 140, a conversion or reaction of the trace data is performed into corresponding characters Z by means of a handwriting recognition.

yet taken place prior to the step 140 is preferably an association of the detected writing track data to the inputting person, ie here to the first person P 'z. B. is represented by the driver. This mapping is performed in a step 130, wherein by means of the position data, preferably the initial position data, it is recognized that the hand itself 'is and thus the person P' on the left virtual writing surface 24 assigned. Then, in the next step 140, the handwriting recognition can be optimized based persons, preferably 'trained on already by this per- son P or individual data symbols and characters is resorted to.

Thus, not only a general detection of the position and movement of the hand, but also a Handschriftener- carried identification and / or assignment to a virtual writing surface. Besides being able to recognize handwriting to assign a specific person, is by means of the sensor 23 reached assignment to different writing surfaces also possible to assign the recognized or calculated trace data for a specific function. For example, the first virtual writing surface 24 'of the driver's position is associated, so that there can be realized inputs as a driver-function-specific input recognized and permitted. This may, for example functions for querying and setting of vehicle data, eg for engine management and the like, which should not be executable by others. The other, right-hand writing surface 24 '', however, the function of a passenger is assigned, so that input local be enabled only for corresponding features. Thus, a function-specific differentiation can be carried out financing of inputs in a simple way.

FIG. 3 shows as a further embodiment, the input of a person P at a device of the invention with a sensor 23, which four mutually spatially beabstan- finished sensors 21 has. The sensors 21 span a virtual writing surface 24 which can be operated without contact by means of the hand 40th The person P is, for example, the driver of a vehicle, which makes 23 and nachgeschalte electronics, inputs to a navigation system via the inventive sensor system. The driver P is located on the driver's seat 10 in which a conductive film 11 'is integrated, which is connected to a signal generator 11 (see also Fig. 1).

The signal generator 11 then generates a modulated signal S which is coupled through the foil 11 'in the body of the person P and is transmitted via the hand 40 up to the input device or sensor 23rd The sensors 21 are capacitive in this example, sensors which detect both the posi- tion of the hand itself and the coupled-in signal S based on field-electric interaction. It takes advantage of the physical phenomenon, therefore, to urge the up kicking interaction on the field of sensor 23 prevailing E-field with a modulation of data or information and to receive them through the sensor 23rd Thus mation about the person P on input collected and processed later as additional information technology.

The proposed method and the invention for non-contact input of characters is particularly well suited for use in user systems, which are integrated into a vehicle, such as in navigation systems. The spaced-apart sensors be located on the writing surface, or where the input is, detect the approach of the hand or of the finger and detect the position and movement, so that the user can perform non-contact on a virtual writing surface handwritten input. The position data acquired and calculated in the evaluation electronics indicate the lettering or described, the trace back and advertising used as the input data for a handwriting recognition. This in turn results from a general or even individual handwriting recognition and provides the characters are to be forwarded to the respective applications. The sensor can be easily installed at any location.

With the proposed solution the problem of an optimum installation location for input or writing surfaces is thus released. Mechanical input devices can be dispensed with due to the sensor and the thus created virtual or imaginary writing surfaces. Due to the spatial association of several sensors at certain sub-areas can be realized a personal and / or functionally related assignment, especially in the area of ​​automotive applications. Thus, the ergonomic problems at forward / reverse steering vehicles, right / left-handed or driver / passenger combinations by a versatile modi- ducible installation method of imaginary writing surfaces can for example be dissolved in the vehicle interior. Examples of the arrangement of imaginary writing surfaces are the center console, the center armrest, the driver or passenger door, the area above the steering wheel, the glove compartment cover, etc.

The absence of non-contact or pressure-sensitive input devices are required, also results in a cost advantage. Also, no structural protection measures such. For example, against water, dust or the like, is required. By the additional use of signal transmitters and signal receivers is a more extensive individualization of the input, in particular a user discrimination is possible. The calculated by means of the invention, input data or characters may be used for many applications such as for example, used for input of navigation destinations, phone numbers and the like. The invention is not limited to the specifically described in this application examples.
