CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application claims the benefit of U.S. Provisional Application Ser. No. 60/503,188, filed on Sep. 16, 2003, which is expressly incorporated herein in its entirety by reference thereto. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to a display device, e.g., for a motor vehicle, having a touch screen for the visual display of information and for the input of commands, and having an actuator for moving the touch screen in a direction essentially perpendicular to the touch screen. The present invention also relates to a navigation system, e.g., a navigation system for a motor vehicle. 
     BACKGROUND INFORMATION 
     A touch screen is described, for example, in German Published Utility Model No. 201 02 197, which is expressly incorporated herein in its entirety by reference thereto. German Published Utility Model No. 201 02 197 describes a touch screen for visually representing electronic signals and for inputting characters and symbols by touching the screen for confirmation purposes. It includes a functional plane for visual representation and touch input and a higher-situated protective plane corresponding thereto that is deformable at certain points. In this context, when certain points of the functional plane are selected by touching-type contact across the protective plane, at least one confirmation signal is generated for the user&#39;s sense of touch (haptic stimulus) that is perceptible at the position of the point of contact in the deformed protective plane, and the confirmation signal for the sense of touch (haptic stimulus) is generated by vibration elements eccentrically positioned within and/or underneath the functional plane. In addition, in the touch screen described in German Published Utility Model No. 201 02 197, the generated vibrations are transmitted from the functional plane to the protective plane as the result of direct contacting of the two planes and/or via the edge regions of the planes by rigid or elastic connecting elements.

The spot thus displayable may be, for example, an operating element depicted on the touch screen, a key depicted on the touch screen, a road represented on the touch screen, a settlement, small village or collection of houses represented on the touch screen, a place information represented on the touch screen, etc. 
     According to an example embodiment of the present invention, a navigation system, e.g., for a motor vehicle, includes a touch screen for the visual display of a geographical map or road map and for detecting a touching of the touch screen (by a user of the navigation system), and an actuator for moving the touch screen in a direction substantially perpendicular to the touch screen as a function of a position at which the touch screen is touched (by the user). In an example embodiment, the navigation system may include a display device having one or more of the aforesaid features. 
     In an example embodiment of the present invention, a road may be displayable on the touch screen. The road displayed on the touch screen, in response to touching by the user, may be recognizable for the sense of touch of the user by a movement of the touch screen. 
     In an example embodiment of the present invention, a settlement may be displayable on the touch screen. The settlement displayed on the touch screen, in response to touching by the user, may be recognizable for the sense of touch of the user by a movement of the touch screen. 
     In an example embodiment of the present invention, place information may be displayable on the touch screen. The place information displayed on the touch screen, in response to touching by the user, may be recognizable for the sense of touch of the user by a movement of the touch screen. 
     Further prominent landmarks may also be displayable on the touch screen. They, or a portion of these prominent landmarks displayable on the touch screen, in response to touching by the user, are recognizable for the sense of touch of the user by a movement of the touch screen. 
     According to an example embodiment of the present invention, in a method for operating a touch screen for the visual display of information and for the input of commands, the touch screen may be moved by more than 2 mm in a direction substantially perpendicular to the touch screen. 
     According to an example embodiment of the present invention, in a method for operating a touch screen for the visual display of information and for the input of commands, the touch screen may be moved in a direction substantially perpendicular to the touch screen for confirming a command input using the touch screen. In this context, in an example embodiment of the present invention, the touch screen may be moved by more than 2 mm in the direction substantially perpendicular to the touch screen. 
     In the aforesaid methods, the touch screen may be moved by more than 3 mm, e.g., by more than 4 mm, in the direction substantially perpendicular to the touch screen. 
     In the aforesaid methods, to confirm the command input using the touch screen, the touch screen may be moved for a duration between 50 ms and 800 ms, e.g., for a duration between 100 ms and 400 ms, in the direction substantially perpendicular to the touch screen. 
     In the aforesaid methods, the touch screen may be moved periodically in the direction substantially perpendicular to the touch screen to confirm the command input using the touch screen. 
     In the aforesaid methods, the touch screen may be moved periodically with a frequency between 10 and 80 Hz in the direction substantially perpendicular to the touch screen to confirm the command input using the touch screen. 
     In the aforesaid methods, the touch screen may be moved with a decaying oscillation in the direction substantially perpendicular to the touch screen to confirm the command input using the touch screen. 
     In the aforesaid methods, the touch screen may be moved in the direction substantially perpendicular to the touch screen when a user of the touch screen touches it at a spot displayable by the touch screen. 
     According to an example embodiment of the present invention, a method for operating a navigation system having a touch screen for the visual display of a geographical map or road map includes detection of a touching of the touch screen by a user of the navigation system at a position highlighted for accentuation on the touch screen, and a moving of the touch screen in a direction substantially perpendicular to the touch screen. 
     A perpendicular or vertical movement of the touch screen does not rule out that the touch screen is also movable in other directions at the same time. Therefore, a perpendicular movement of the touch screen within the context hereof may mean, e.g., that a movement has a suitable perpendicular component. However, it may be provided that the touch screen is only moved in a range of 80° to 100° if a movement in a direction substantially perpendicular to the touch screen is mentioned in the aforesaid. 
     A motor vehicle within the present context may be, e.g., a land vehicle that is able to be used individually in road traffic. However, motor vehicles within the present context are not limited to land vehicles having combustion engines. 
     Further aspects and details are set forth below in the following description of exemplary embodiments with reference to the appended Figures.

     DETAILED DESCRIPTION 
       FIG. 1  illustrates an exemplary embodiment of a cockpit  1  of a motor vehicle. In cockpit  1 , a steering wheel  2  is positioned below an instrument panel or dashboard  3 . Instrument panel  3  has a display device  4  positioned next to steering wheel  2 .  FIG. 2  illustrates an exemplary embodiment of a cockpit  11  of a motor vehicle, a steering wheel  12  being positioned below an instrument panel  13  in cockpit  11 . However, departing from the exemplary embodiment illustrated in  FIG. 1 , a display device  14  is positioned in steering wheel  12 . 
       FIG. 3  illustrates—as a possible exemplary embodiment of a display device  4  or  14 —a display device  20  having a touch screen  21 , illustrated in plan view, for the visual display of information and for the input of commands. Touch screen  21  is connected, from the standpoint of data-systems engineering, to a control  25  from which a signal A having information to be displayed on touch screen  21  is transmitted to touch screen  21 . From touch screen  21 , control  25  receives a signal P that indicates where a user of touch screen  21  is touching touch screen  21  and/or—if provided—whether the user is pressing on a position, characterized as input position, on touch screen  21  such that it is to be understood as an input. 
     At the lateral edges of touch screen  21 , display device  20  has actuators  22  and  23  for moving touch screen  21  in a direction substantially perpendicular to touch screen  21 . Control  25  transmits control signals S 1  and S 2  to actuators  22  and  23 , which trigger actuators  22  and  23  such that touch screen  21  is able to be moved by at least 2 mm, e.g., by approximately 4 mm, in the direction substantially perpendicular to touch screen  21 . 
     It may be provided that an input is effected by simple touching of touch screen  21 . However, provision may also be made that an input is not effected by simple touching of touch screen  21 , but rather by, e.g., light, pressing on touch screen  21 . In this case, it may be provided that touch screen  21  is moved not only for confirming a command input using touch screen  21 , but also in response to touching certain positions on touch screen  21 . The movements may be differentiated for a user. Thus, a deflection of touch screen  21 , caused by touching a specific position on touch screen  21 , may last as long as the touching of this or another position leading to a comparable deflection persists. On the other hand, a short-duration deflection may take place as confirmation of the input of a command, as is explained in the following with reference to  FIGS. 4 to 6 . 
       FIG. 4  illustrates an exemplary embodiment of a movement  30  of touch screen  21  as confirmation of an input using touch screen  21 , represented over time t. M designates the deflection of touch screen  21  in a direction perpendicular to touch screen  21 . In this context, the deflection of touch screen  21  may take place for a duration between 50 ms and 800 ms, e.g., for a duration between 100 ms and 400 ms. 
     In an example embodiment, to confirm the command input using the touch screen—as illustrated in  FIG. 5  as deflection M of touch screen  21  over time t—touch screen  21  is movable with a decaying oscillation  32  in the direction perpendicular to touch screen  21 . Decaying oscillation  32  has an envelope curve  33  and  34 , respectively, having an exponential component. In this context, envelope curve  33  and  34  has, for example, a term to or a term b t , where a and b represent variables. Thus, envelope curve  33  and  34  may be a function of a 1 +a 2 *t a3  or b 1 +b 2   t , where a 1 , a 2 , a 3 , b 1  and b 2  represent variables. It may be provided that envelope curve  33  and  34  includes a term t 2  as the highest power. 
     In addition, decaying oscillation  32  has a frequency between 10 and 80 Hz. A frequency of approximately or around 40 Hz may be provided. 
       FIG. 6  illustrates a control signal  35  for moving touch screen  21  in a direction substantially perpendicular to touch screen  21  over time t in sampling points, one sampling interval being 51.2 μs. Control signal  35  is illustrated normalized to its maximum value. It has a frequency of 38.1 Hz, and has decayed after 210 ms, the decay taking place according to a quadratic relation. 
     Display devices  4  and  14 , built in accordance with display device  20 , may replace a display and operating device described in PCT International Published Patent Application No. WO 00/21795, which is expressly incorporated herein in its entirety by reference thereto, retaining its menu-driven functionality.

       FIG. 7  illustrates display device  40  having a mask base. Display device  40  displays five operating elements  41 ,  42 ,  43 ,  44  and  45  arranged as ellipses. By touching or pressing operating element  42  in  FIG. 7 , a mask for operating a radio is called up, and by touching or pressing operating element  43  in  FIG. 7 , a mask for operating a CD player is called up. 
     By touching or pressing operating element  45  in  FIG. 7 , a mask, illustrated in  FIG. 8 , for operating an air conditioner is called up. In the mask illustrated in  FIG. 8 , temperature information about the individual locations in the passenger compartment together with operating elements  50 ,  51 ,  52 ,  53  and  54  are displayed, the temperature information relating to currently set temperatures which may be changed via operating elements  50 ,  51 ,  53  and  54 . 
     The representation illustrated in  FIG. 8  having the title “temperature” and the display of a passenger compartment  55  of a motor vehicle makes clear that the temperature setting in the passenger compartment is adjustable individually and specific to the seat. Operating element  50  indicates that a temperature of 19° C. is set for front driver&#39;s seat  56 . Operating element  53  indicates that a temperature of 20° C. is set for front passenger&#39;s seat  57 . For rear seats  58  and  59 , 19° C. is set on the left side and 17° C. is set on the right side. Operating element  52  has an assignment, i.e., a function assignment, which is represented in the display field by “Back”. 
     By touching or pressing operating element  41  in  FIG. 7 , a mask, illustrated in  FIG. 9 , for operating a navigation system is called up. The mask illustrates a segment of road map  60  of the instantaneous vehicle location, as well as, above road map  60  in a field  61 , the destination and the distance to the destination.

An alphabetical-letter selection line  88 , as well as operating elements  86 ,  87  and  89  are represented in field  80 . Alphabetical-letter selection line  88  is movable up or down by touching or pressing operating elements  86  and  87 , respectively. A highlighted alphabetical letter may be selected by touching or pressing operating element  89 . 
     By touching or pressing operating element  44  in  FIG. 7 , a mask, illustrated in  FIG. 12 , for operating a telephone is called up which, in a field  90 , displays selector buttons for a telephone. Also displayed by the submask as illustrated in  FIG. 12  are operating elements  92 ,  93 ,  94 ,  95 ,  96 ,  97 ,  98  and  99  which replace operating elements  3   a ,  3   b ,  3   c ,  3   d ,  3   e ,  3   f ,  3   g  and  3   h  described in PCT International Published Patent Application No. WO 00/21795. The selector buttons, displayed in field  90 , for a telephone are arranged as operating elements by which a telephone number may be dialed. 
     Also shown in the masks and submasks illustrated in  FIGS. 7 to 12 , respectively, are operating elements  100 ,  101 ,  102 ,  103  and  104  which correspond to operating elements  41 ,  42 ,  43 ,  44  and  45 . 
     A haptic feedback is produced with the aid of operating elements  41 ,  42 ,  43 ,  44 ,  45 ,  50 ,  51 ,  52 ,  53 ,  54 ,  62 ,  63 ,  64 ,  65 ,  66 ,  67 ,  68 ,  69 ,  72 ,  73 ,  74 ,  75 ,  76 ,  77 ,  78 ,  79 ,  82 ,  83 ,  84 ,  85 ,  86 ,  87 ,  89 ,  92 ,  93 ,  94 ,  95 ,  96 ,  97 ,  98 ,  99 ,  100 ,  101 ,  102 ,  103  and  104 . To that end, the touch screen of display  40  is moved in a manner described with reference to  FIGS. 4 to 6  when, by touching or pressing suitable operating element  41 ,  42 ,  43 ,  44 ,  45 ,  50 ,  51 ,  52 ,  53 ,  54 ,  62 ,  63 ,  64 ,  65 ,  66 ,  67 ,  68 ,  69 ,  72 ,  73 ,  74 ,  75 ,  76 ,  77 ,  78 ,  79 ,  82 ,  83 ,  84 ,  85 ,  86 ,  87 ,  89 ,  92 ,  93 ,  94 ,  95 ,  96 ,  97 ,  98 ,  99 ,  101 ,  102 ,  103 ,  104  and  105 , respectively, a user input is implemented, i.e., when the touching, for example, is performed long enough and/or sufficient pressure has been exerted on the touch screen. This may be provided for use in a motor vehicle, since an operator, thus, for example, the driver of a motor vehicle, in this manner receives a confirmation of his/her input without having to look at the display. Safety while driving may thereby be increased. 
     It may be provided that the touch screen is moved in the direction of a user when operating element  41 ,  42 ,  43 ,  44 ,  45 ,  50 ,  51 ,  52 ,  53 ,  54 ,  62 ,  63 ,  64 ,  65 ,  66 ,  67 ,  68 ,  69 ,  72 ,  73 ,  74 ,  75 ,  76 ,  77 ,  78 ,  79 ,  82 ,  83 ,  84 ,  85 ,  86 ,  87 ,  89 ,  92 ,  93 ,  94 ,  95 ,  96 ,  97 ,  98 ,  99 ,  101 ,  102 ,  103 ,  104  or  105  is touched, so that the feeling of a three-dimensional operating element ensues for the user. It may further be provided that the touching of suitable operating element  41 ,  42 ,  43 ,  44 ,  45 ,  50 ,  51 ,  52 ,  53 ,  54 ,  62 ,  63 ,  64 ,  65 ,  66 ,  67 ,  68 ,  69 ,  72 ,  73 ,  74 ,  75 ,  76 ,  77 ,  78 ,  79 ,  82 ,  83 ,  84 ,  85 ,  86 ,  87 ,  89 ,  92 ,  93 ,  94 ,  95 ,  96 ,  97 ,  98 ,  99 ,  101 ,  102 ,  103 ,  104  or  105  is only interpreted as a user input after a brief time span has elapsed. In this case, the touch screen of display  40  is moved in a manner described with reference to  FIGS. 4 to 6 . 
     A haptic feedback may be provided with regard to road map  60  in field  61  in  FIG. 9 . Thus, for example, the touch screen may be moved in the direction of a user when a settlement  120 , a road  121  or place information  122  is touched, so that the feeling of a three-dimensional contour of road map  60  ensues for the user. In addition, it may be provided that a destination is input by touching place information  122  on road map  60 . In this context, a successful selection may result for the user by a haptic feedback described with reference to  FIGS. 4 to 6 . 
     The device may also be transferable to a multifunctional operating device as described in German Published Patent Application No. 101 39 693, which is expressly incorporated herein in its entirety by reference thereto. For example, the rotating element described in German Published Patent Application No. 101 39 693 may be replaced by operating elements arranged according to operating elements  86  and  87 .
