Abstract

The vehicle has a displaying device (22) displaying graphical objects (32, 34) and a cursor indication i.e. frame (36), and an operating device e.g. rotary push sliding actuator (16) and control panel, which is different from the display device. The control device is coupled with the display device, and distance of the cursor indication to the graphical objects is changed by the control device. A voice recognition device (S) detects a voice command and selects a function from selected group of functions based on the voice command. An independent claim is also included for a method for selecting a function from a set of functions of a vehicle.

Description

The The invention relates to a vehicle having a plurality of functions and a selector for selecting one of the functions having. The invention also relates to a method for selecting one of the function. Examples of a function are a Play a specific song from a music database by a player of a vehicle or providing information about a particular destination by a navigation device. Generally, in the context of this invention a function is a Sequence of related processing steps understand which of a control unit of the vehicle, z. B. an infotainment system or a driver assistance system, be performed to a predetermined technical effect to achieve.

Vehicles, such as As passenger cars, provide a variety of such functions ready. To use a specific function, an operator must usually select the function first. This is mostly about faucets of the control panel of the Vehicle possible. In the case of an infotainment system includes Such a selector often a display unit on the the functions are listed. Due to the variety of functions An operator can not always select all of them Functions are displayed at the same time.

Instead of of which can be names for the individual Functions or even just functional groups as entries in different menus of a menu structure be listed. On the display unit is then one each of the menus currently displayed. To a desired To select function, the operator must select starting from a central menu. In this central menu are several function groups as selectable menu entries listed. Examples of a function group are for. As the music playback, telephony, navigation or climate control of the vehicle. By selecting a menu entry of the central Menus, an operator enters a submenu, in which individual functions from the function group can be selected are.

at It can also be very extensive functional groups that one Function not listed immediately in the submenu is, but that from the submenu out more submenus selectable with further menu entries are. This can make a selection of a function a lot of time and Attention of the operator. For the case that the operator is the driver of the vehicle exists by operating the infotainment system while the risk that the selection of a function the driver too long from the road distracting.

Around To reduce the distraction of a driver, a selection device be equipped with a voice recognition device. With a Speech recognition device is a voice command, so a single, spoken word or also a whole spoken sentence, machine recognizable. In a selection device with speech recognition device is usually the menu structure with the central one Menu and the submenu replicated in such a way that a driver by a first voice command first a Can select function group and then by means of a second voice command the single function. This reduces the likelihood that the speech recognition device misrecognizes a voice command.

By a speech recognition device, it is possible that a Driver during picking the traffic observed. A disadvantage of a voice-controlled selection device is against that the driver has the menu items of that menu from which he can voice an entry should also select acoustically via a voice output must be presented. The reproduction of each Menu entries about language take a lot Time to complete and also means that the driver information to hear him at a given moment maybe not at all interested.

From the DE 10 2008 051 757 A1 a multimodal user interface of a driver assistance system for entering information is known in which graphic objects are displayed on a touchscreen of the driver assistance system, to each of which a plurality of functions can be selected.

For example can be on a road map of a navigation device individual destinations are displayed as such objects. Is this Destination example, a restaurant, can then, for example, functions in the restaurant to set the next destination of the navigation or a telephone connection to a restaurant administration over the Mobile phone or opening hours of the restaurant over to determine an internet connection. To a single object To select the touch screen, an operator must be on press the object. From the functions that the object can then be selected by a corresponding voice command is pronounced.

An advantage of this selection device is that no central menu is needed, from which the operator first selects that group of functions via voice commands, from which they then Finally, you can select the desired function. By tapping on an object on the touch screen, the group of functions is selected directly, from which the operator can then select the voice command.

Indeed is the number of objects limited, at the same time on a touch screen are representable. This is also the number of a given Time limited to selection of available groups of functions. In addition, the selection device for a driver is not usable in situations where he does not have the necessary Time has to catch an object on the touch screen first to pin it down with a finger and finally long enough to press the voice recognition device to activate. Once the driver in this process once the view from the touchscreen, his finger will also be pointing an object with high probability slip.

It Object of the present invention, other options to close it in a vehicle a variety of To be able to select functions.

The Task is by a vehicle according to claim 1 solved. The object is also achieved by a method according to claim 9 solved. Advantageous developments of the invention are by given the dependent claims.

The Vehicle according to the invention has a plurality of functions and a selector for selection one of the functions. The selection device comprises a display device, by means of which graphic objects and a cursor representation can be displayed are. The objects are each assigned a group of functions and one of the groups of functions can be selected. For this, the cursor representation and the objects are relative movable relative to each other and a group associated with an object Functions is then selected when a distance of the cursor representation to the object is smaller than a predetermined value.

The Selection means further comprises one of the display means different operating device. This operating device is with the Display device coupled. With it can be a distance of the cursor representation to be changed to an object.

The Selection device also includes a speech recognition device, with which a voice command is detectable. The speech recognition device is further adapted depending on the detected Voice command from the selected group of functions to select a function. In the inventive Vehicle is also particularly easy to select one of the objects when an operator during the selection the attention for a moment from the display device must turn away and, for example, on the road must focus. Because the cursor representation and the objects are relative are movable to each other, the distance between the cursor representation and a desired object step by step reduce. So is the operator in between by the display device After being distracted, she has to go back to the display has turned, the selection does not start over. She can do the aligning the cursor representation and the desired object to each other Continue using the operating device where it interrupted Has.

By the movable cursor representation or by the movable objects is also given the opportunity during the Operating new objects with corresponding, additional functions on the Display device. For example, the cursor representation by means of the operating device to an edge of the display device controlled by a corresponding change Displaying the display device gives the impression that from beyond the edge new objects on the edge of the display appear. Similarly, in the case that by means of the operating device the position of objects on the display device changeable is to be created the possibility of objects over to move an edge of the display out and for make other objects visible on the display. All in all So we made it possible, a bigger one To provide number of objects with assigned functional groups, than can be displayed on the display device at a given time.

The vehicle according to the invention is in an advantageous Way further developed that at least with the operating device an operator action is executable, by which on the Display device independent of a current distance the cursor representation to an object a predetermined change the distance is effected. In other words, in this development of the vehicle according to the invention the cursor representation shifted by a predetermined distance when the operating device is served once. For example, with a tilting control lever mean that by a single tilt of the lever to the right the Cursor display on the display to a specific Distance is moved to the right.

By applying a cursor to an object regardless of a current distance Predetermined change of the distance is effected, there is the advantage that an operator can estimate by a quick glance at the display device, how often it must operate the control device to merge the cursor representation and a desired object such that the object associated group of Functions is selected. In this case, the operator no longer has to look at the display device during the execution of the individual operator actions and can concentrate on the traffic.

A further advantageous embodiment of the invention Vehicle results when the operating device is an approximate and / or a touch sensor, by their respective measurement signals the speech recognition device is activatable. To a speech recognition The operator must therefore simply with a Body part, so for example a hand, in the vicinity of Proximity sensors come or the touch sensor touch. Both with the proximity sensor and in the case of the touch sensor, the measurement signals are respectively preferably in response to an infrared signal and / or a change of capacity. By doing the speech recognition device is not operated continuously, but only after a corresponding measurement signal from an approximate and / or touch sensor was generated, the results Advantage that the operator can control which of her vocalizations evaluated by the speech recognition device as a voice command should be. This reduces the advantage in an advantageous manner Risk of incorrect recognition of a voice command.

A further advantageous embodiment of the invention Vehicle results when the operating device a rotary-push-button or a rotary push-slide actuator. A turn-push actuator consists of a rotatably mounted rotary wheel, in which both Turning around an axis of rotation as well as by pressing the wheel in the direction of the axis of rotation in each case signals can be generated, based on which the respective operator action is recognizable. In a turn-push slide controller signals are additionally by a lateral deflection of the rotary wheel Signals can be generated. A turn-push actuator and a turn-push slide actuator allow an operator in an advantageous manner, generate a variety of different signals to change to be able to control a distance of the cursor representation to an object.

A advantageous development results in an inventive Vehicle with a turn-push actuator or a rotary push-slide actuator, if in a cap of the rotary wheel an approximate and / or a touch sensor are / is arranged. That's it for an operator particularly easy, after a selection a group of functions to activate the speech recognition device. To operate the rotary knob on this applied hand of the operator just has to be relocated a bit to the speech recognition device to activate.

A Further advantageous development results when the operating device includes a touchpad. A touchpad has a touch-sensitive Surface on where a position on the surface determines can be at the one finger of an operator the surface touched. A touchpad offers the advantage of being for an operator movements of objects or of a cursor representation on the display device particularly simple and intuitive with a Course of a touch on the touch-sensitive Surface of the touchpad can be associated. This advantageously offers the possibility of an operator to provide a particularly easy to learn control device.

In Connection with a touchpad results in an advantageous development of the vehicle according to the invention, when the speech recognition device by pressing the touchpad for a predetermined time Time or by touching the touchpad according to a predetermined pattern is activated. This allows an operator after selecting a group of functions, the speech recognizer activate without having to deal with one hand.

The invention also includes a method for selecting a function from a plurality of functions of a vehicle. The vehicle has a display device, an operating device and a speech recognition device. According to the method of the invention, at least one graphical object and one cursor representation are provided on the display device, wherein the at least one object is assigned a group of functions, and wherein the cursor representation and the objects are movable relative to one another. A distance of the cursor device to at least one of the graphic objects is changed in a further step of the method as a function of a control action performed on the operating device of the vehicle. In a next step, it is checked whether a distance of the cursor representation of an object falls below a predetermined value. If so, the group of functions associated with the object is selected. In a further step, a voice command is detected by means of the speech recognition device and depending on the detected Sprachbe a function is selected from the currently selected group of functions. If the vehicle according to the invention is operated according to the method according to the invention, then the advantages already described in connection with the vehicle according to the invention result.

The inventive method is similar as the vehicle according to the invention in an advantageous Formed way when detecting the voice command by an actuation of the operating device triggered becomes. Preferably, the pressing is done by touching a touch-sensitive surface of the operating device.

When Cursor representation is preferably a picture element by means of the display unit shown. Such a picture element can, for. As a frame or to be an arrow. Such a picture element has the advantage that a change of position after an operator action, which is performed on the control, visually simple to pursue. This allows an operator as well then get along well when operating the selection device, if the display unit and the operating device at an angle to each other and thereby, for example, a movement of a lever of the Control forward on an upright screen a display unit causes a change between two objects, which are arranged one above the other on the screen.

The inventive method is also characterized in advantageously further developed that as a cursor representation a Object shown graphically changed when a distance the object to a position associated with the cursor representation, falls below the predetermined value. An example for such a kind of cursor representation is an inverting of the colors an object. Changing the appearance of an object, whose assigned functions are selected it to an operator to detect in a particularly short time which Group of functions is currently selected. This is special then beneficial if the operator only for a short time Moment can look at the display device.

According to one another development of the method according to the invention is used to change the spacing of the cursor representation an object a position of the cursor representation on the display unit or a position of the object on the display unit changed. When changing the position of the cursor representation can provide a continuous change of position be. However, the cursor display can also be used for every operator action be moved from one object to another.

By Changing the position of the cursor has the advantage that a driver by a quick look at the display device can estimate how far he has the cursor to a particular object has to move. Then he can look again to the street and the cursor, without to view the display device, by means of the operating device to head for the desired object.

Becomes instead of the cursor position, a position of the object on the display unit changed, the cursor representation, z. A frame, placed at a predetermined location on the display unit, and there may be various objects on the display unit be strung, then by operating the control device to select a specific group of functions in alternation be brought into line with the cursor representation. This results The advantage is that very long lists of function groups using the selection device handled in a clear form can be. Besides, a position of that is Object whose assigned functions are currently selected are, by the invariable position of the cursor representation predetermined, so that the object is always light on the display unit can be found.

The The invention will be described in greater detail below with reference to examples explained. To show:

The Examples illustrate preferred embodiments of the invention represents.

In the 1 shown center console 10 is part of an in 1 not shown passenger car. The center console 10 extends between a windshield 12 and an armrest 14 of the passenger car. On the center console 10 are fittings for operating the passenger car. From the faucets are in 1 a turn-push slide actuator 16 and a control panel 18 with a rocker switch and a button. The rocker switch and the button are in 1 not shown further. The control panel 18 is in a steering wheel 20 of the passenger car and can thus be reached while driving by a driver with one hand, without being the hand of the steering wheel 20 must solve.

In the center console 10 is also a screen 22 installed, over which an operator information can be displayed. At an upper end of the windshield 12 is at a rearview mirror 24 a microphone 26 appropriate. With the microphone 26 Voice utterances of an operator and other sounds from the inside of the passenger car can be detected. The microphone 26 is with an in 1 not shown speech recognizer coupled, based on the microphone 26 detected speech signals can perform an automatic speech recognition.

Instead of the rotary-push-slide actuator 16 can on the armrest 14 also a touchpad in the center console 10 be installed. The turn-push-slide actuator 16 , the rocker switch and the control panel button 18 , the microphone 26 and the ad 22 are connected to a control unit 28 connected. The control unit 28 can receive signals from the turn-push-slide actuator 16 and the components of the control panel 18 receive. Furthermore, the controller controls 28 a graphics memory of the screen 22 , resulting in the screen 22 displayed graphics by the controller 28 can be changed. In the control unit 28 The speech recognizer is also integrated. The operation of the control unit 28 and the other components of the center console 10 will be explained in connection with the following figures.

In 2 is shown as related to 1 described passenger car playing a song is enabled. In the example, an operator selects a music album of a music artist and then determines which music piece from the album is to be played.

In 2 are for elements that are already related 1 have been described, the same reference numerals as in 1 forgive. In 2 are from the in 1 already described elements of the screen 22 , the rotary push-slide actuator 16 , the microphone 26 as well as the control unit 28 shown.

In 2 are different from 1 nor a speaker L and a mobile telephone system M of the passenger car shown. By means of the loudspeaker L can by the control unit 28 an audio signal is played in the passenger car. About the mobile telephone system M can by the control unit 28 a radio link F with an Internet service provider (ISP - Internet service provider) are produced. The control unit 28 can thus receive information from a computer network by means of the mobile telephone system M.

In the example is already related to 1 described screen 22 giving the operator the opportunity to choose from available music albums. The music data for a single music album are stored respectively on a CD storage medium (CD - Compact Disc). The CD storage media are in a CD changer 30 in a trunk of the passenger car. By already related to 1 described control unit 28 has been determined after starting an engine of the passenger car, which CD storage media is currently in the CD changer 30 are located. To each CD storage medium, that is, to each music album, generates the controller 28 in the graphics memory of the screen 22 in the way data entries in memory cells of the graphics memory that on the screen 22 for each album a graphic object 32 . 34 becomes visible.

In the event that in the CD changer 30 more CD storage media are available than graphic objects 32 . 34 on the screen 22 can be displayed in a clear way are from the controller 28 in the graphics memory of the screen 22 less graphic objects 32 . 34 saved as there are actually music albums. For that at a given time not by a graphical object 32 . 34 on the screen 22 represented albums a corresponding graphical object is generated at a given time and then the operator then indicated that also more albums are available.

To select a music album, the operator uses the rotary-push-slide controller 16 , As in 1 It can be seen, this controls is so in the center console 10 placed so that it can be easily reached by the driver by hand during a journey with the passenger car. In particular, the driver does not have to look away from the roadway to the turn-push-slide actuator 16 to find. Also the screen 22 is so in the center console 10 attached that the driver his view only briefly from the Road to get an overview of which music albums are selectable when selecting the music album.

In the in 2 As shown in the example, the driver wants to select a music album that is played by the in 2 with the reference number 34 represented graphical object is represented. To highlight the graphic object 32 . 34 that at any given time counts as the selected album is controlled by the controller 28 on the screen 22 a frame 36 at a fixed position on the screen 22 displayed. To the graphic object 34 by means of the frame 36 to mark as selected, the driver must select the graphical object 34 first on the screen 22 move to the left, leaving the graphic object 34 on the frame 36 moved to and finally from the frame 36 is framed. For this purpose, the driver at the turn-push-slide actuator 16 a wheel 38 according to in the 2 turn left. The resulting movement of the rotary wheel 38 by turning it is in 2 through an arrow 40 symbolizes.

The wheel 38 the rotary-push-slide actuator 16 is with a base of the rotary push-slide actuator 16 connected. The wheel 38 can turn on the one hand to an axis, as in 2 is shown by arrows. In addition, the wheel can be 38 tend towards the pedestal, allowing tilting movements with the wheel 38 are executable. Possible tilting directions are in 2 represented by arrows. By turning the rotary wheel 38 as well as by tilting the same can each generate a specific electrical signal to the control unit 28 is transmitted. Also by pressing the wheel 38 can generate another electrical signal. The wheel 38 finally has a cap K with a touch sensor. An electrical signal is generated by the touch sensor whenever a finger of an operator or another body part touches the cap K. The detection of a touch may be based on a change in capacitance in the cap K in the touch sensor. But it can also be provided to install an infrared sensor as a touch sensor in the cap K. Also, the electrical signal of the touch sensor of the cap K is to the controller 28 transfer.

By turning the rotary wheel 38 in the direction 40 is by the rotary-push-slide controller 16 generates a corresponding electrical signal from the control unit 28 Will be received. The control unit 28 then shifts in the graphics memory of the screen 22 the data representing the graphical objects 32 . 34 on the screen 22 result, in the way in other memory cells of the graphic memory, that the graphic objects 32 . 34 on the screen 22 their position in 2 change to the left. In 2 is this movement of graphic objects 32 . 34 through arrows 40 ' indicated.

By moving the graphical objects 32 . 34 on the screen 22 approaches the graphic object 34 the frame 36 , The driver can by turning the wheel again 38 the graphic object 34 finally in the frame 36 position.

Instead of the rotary-push-slide actuator 16 However, the driver can also the rocker switch 42 in the control panel 18 at the steering wheel 20 of the passenger car. The rocker switch 42 is tilted up, down, right and left. This can be done with the rocker switch 42 generate four different signals. By button 44 of the control panel 18 An electrical signal is generated whenever the button is pressed 44 is pressed. The signal of the button 44 can also be connected to the control unit 28 be transmitted.

By the operator an area 40 '' of the rocker switch 42 presses, generates the rocker switch 42 a signal through which in the control unit 28 a shift of graphical objects 32 . 34 caused by the rotation of the wheel 38 in the direction 40 is triggered.

The position of the frame 36 on the screen 22 can also be changed up and down. This must either the wheel 38 be tilted upwards or downwards or the rocker switch 42 be operated accordingly. Will the frame 36 moved upwards, it can be by turning the rotary knob 38 in horizontal direction on one of three fields 46 . 46 ' . 46 '' place. By marking one of the fields 46 . 46 ' . 46 '' is in the controller 28 Switched between different operating modes. Examples of such modes of operation are controlling the mobile telephone system to establish a telephone connection, controlling an air conditioning system of the car and selecting a destination in a navigation device. Depending on which operating mode is active at a time, are on the screen 22 below the fields 46 . 46 ' . 46 '' other objects shown.

By moving the frame 36 On the other hand, fields can be downwards 48 . 48 ' . 48 '' be marked. Depending on which of the fields 48 . 48 ' . 48 '' can have different settings on a player in the CD changer 30 , such as As a volume, by turning the wheel 38 to be changed

In 3 is the example of 2 continued. Accordingly, in 3 Elements that elements in 2 correspond with the same reference numerals as in 2 Mistake.

As related to 2 described, the operator has the graphical object 34 by pressing the rotary wheel 38 in the frame 36 moved to the graphic object 34 mark as the desired object. To the graphic object 34 , that is to the music album, which through the graphic object 34 is represented, there are several functions by the control unit 28 to be provided. For example, the entire music album can be played or a single track can be selected to play. To select one of these functions, the operator touches the cap K on the rotary wheel 38 , The signal of the touch sensor in the cap K changes thereby. This is done by the controller 28 recognized.

The control unit 28 then activates the already in the description of 1 The speech recognizer S then performs an automatic speech recognition, this automatic speech recognition based on the signal of the microphone 26 is carried out. The operator pronounces the words "Play song number 5" after touching the cap K. This acoustic signal 50 gets from the microphone 26 detected and forwarded as an electrical signal to the speech recognizer S. The speech recognizer S recognizes the spoken word and then selects from the possible in connection with the selected music album functions that relates to the playback of the entire music album.

The control unit 28 then sends a control command to the CD changer 30 , whereby loading the selected music album into a drive of the player of the CD changer 30 is triggered. After the CD media is loaded, the controller sends 28 another command to the CD changer, which triggers the playback of the fifth song of the music album. The CD changer then transmits 30 corresponding music signals to the controller 28 , which plays this over the speaker L.

In order to activate the speech recognizer S, instead of touching the cap K, the operator may also turn the dial 38 Press or the key 44 of the control panel 18 to press. But it can also be provided to operate the speech recognizer throughout. The recognizable by the speech recognizer S vocabulary can at the moment by means of the frame 36 selected object to be customized.

In 4 a driver assistance system is shown. On a screen 60 of the driver assistance system, a road map P is displayed. The display of the screen 60 is through a control unit 62 controlled. The control unit 62 is still with a touchpad 64 and a microphone 66 connected. At the touchpad 64 can be on a touch-sensitive surface 68 be recognized whether this area is touched or pressed by a body part of an operator. In addition, it can be seen where on the surface 68 the touch takes place. By means of the microphone 66 a sound signal can be detected from a passenger compartment of the passenger car. The control unit 62 is finally with a mobile phone system 70 connected. The mobile phone system 70 is able to get data from the controller 62 in a mobile network and to receive data from the mobile network and to the control unit 62 forward.

On the screen 60 is in the in 4 shown a road map P shown. The data on a course of roads shown on the road map P has the controller 62 via the mobile phone system 70 receive. These data were from the controller 62 to display on the screen 60 into a graphics memory of the screen 60 transfer. In addition to the course of the roads are still individual destinations as a single graphical objects 74 . 75 on the screen 60 shown.

The control unit 62 provides several different ways of presenting the road map P on the screen 60 to change. For example, a section of the street plan P may be enlarged on the screen 60 being represented. The street plan P can also be on the screen 60 be moved so that on the screen 60 at the edge of which another section of the streets shown becomes visible. Also in connection with the individual destinations on the screen 60 as graphical objects 74 . 75 are represented by the control unit 62 in each case several actions executable.

In the in 4 As shown, an operator would like a portion of the road map P enlarged on the screen 60 get presented. To do this, the operator presses the surface 68 of the touchpad 64 with a finger 76 , Through the touchpad 64 It monitors how long the touch-sensitive area 68 is pressed. As the operator with her finger 76 for more than a second on the surface 68 presses, through the touchpad 64 generates a signal to the controller 62 is transmitted. Measuring the duration of the touch by the finger 76 can also by the control unit 62 be performed.

Upon detection of a prolonged pressure is by the control unit 62 via the graphics memory of the screen 60 a mark 78 displayed. The mark 78 covers the whole on the screen 60 illustrated road map P. The operator is indicated by the fact that now a function of the control unit 62 can be selected, which refers to the entire road map P. An in 4 not further illustrated speech recognizer in the controller 62 is also activated. That the speech recognizer is ready, is on the screen by an appropriate recording icon 80 displayed.

To select a function, the operator pronounces a name of the function aloud. By means of the microphone 66 becomes a corresponding sound 82 detected. A signal from the microphone 66 is done by the speech recognizer of the controller 62 an automatic speech recognition supplied. By means of the automatic speech recognition words or phrases are recognizable, which represent names for those functions in connection with the entire road map P by the control unit 62 are provided.

When a word is detected that can be assigned to one of the functions, the corresponding function is selected. Subsequently, the control unit leads 62 the actions necessary to provide the function.

In the 5 and 6 is the driver assistance system from the 4 shown again. Accordingly, in the two figures also for elements, the elements in the 4 correspond, the same reference numerals used.

In both figures, a process is shown in which the operator is a function of the control unit 62 want to select, focusing on a single object 75 refers. The operator strokes with his finger over the touch-sensitive surface 68 of the touchpad 64 , The touchpad 64 is in the 5 and 6 shown in a plan view. When stroking in directions, as in 5 through arrows 84 are represented by the touchpad 64 also generates signals. The control unit 62 then generates via the graphics memory of the screen 60 on the screen 60 a frame 78 ' to select objects 74 . 75 on the screen 60 , A position of the frame 78 ' is from the controller 62 always changing as the direction of movement 84 of the over the area 68 stroking finger 76 equivalent. The operator controls the frame 78 ' by stroking until the frame is up 78 ' over the object 75 located.

The object 75 represents a restaurant that can be selected as a destination. To the restaurant can by the control unit 62 but also information about their opening hours are determined. From these and other options, the operator would like to select one.

How to do it in 6 is shown, the operator types with two fingers 76 . 76 ' on the touch-sensitive surface 68 of the touchpad 64 On top of that by the touchpad 64 signal generated activates the control unit 62 the speech recognizer. The speech recognizer can also be activated by not using two fingers 76 . 76 ' on the touch-sensitive surface 68 is typed but with a finger for a longer period of time on the surface 68 is pressed. Instead of two fingers 76 . 76 ' You can also use more than two fingers. It can also be provided another key through which the speech recognizer is activated.

If Speech Recognizer is activated, will appear on the screen 60 the marking frame 78 ' through another marker frame 78 '' replaced. This signals the operator that now a voice command can be spoken.

The operator now speaks a voice command, so that a corresponding sound signal 86 to the microphone 66 arrives. The voice command is the name of a function here. The detected signal is from the speech recognizer of the controller 62 can also be uniquely assigned to a function name in the example. The function thus determined becomes the functions that belong to the object 75 be provided.

In the in the 5 and 6 As shown, the operator would like to know the opening hours of the restaurant. She has therefore pronounced a corresponding voice command. The voice command was issued by the speech recognizer of the controller 62 yes also recognized correctly.
