Input Device

Abstract

An input device, especially for a vehicle, includes a first display for optical display of information, at least a second display arranged above the first display for optical display of information and a touchscreen arranged above the second display for entry of commands by touching an operating surface of the touchscreen.

1 . An input device comprising: 
 a first display for optical display of information;    at least a second display arranged above the first display for optical display of information; and    a touchscreen arranged above the second display for input of commands by touching an operating surface of the touchscreen.    
   
   
       2 . An input device according to  claim 1 , wherein the operating surface is arranged on a side of the touchscreen facing away from the second display.  
   
   
       3 . An input device according to  claim 2 , wherein the touchscreen is connected to the second display.  
   
   
       4 . An input device according to  claim 1 , wherein the distance between the first display and the second display is variable.  
   
   
       5 . An input device according to  claim 1 , wherein the second display is transparent, at least in a large region.  
   
   
       6 . An input device according to  claim 1 , further comprising: 
 a control to drive the second display, so that an operating element or a warning message can be displayed by means of a second display.    
   
   
       7 . An input device according to  claim 6 , wherein an explanation of the operating element or a context of the operating element can be displayed by the first display.  
   
   
       8 . An input device according to  claim 8 , further comprising: 
 an actuator to move the touchscreen in at least one direction.    
   
   
       9 . An input device according to  claim 8 , wherein the second display is moveable by means of the actuator.  
   
   
       10 . An input device according to  claim 9 , wherein the touchscreen is connected to the second display.  
   
   
       11 . An input device according to  claim 1 , wherein the distance between the first display and the second display is variable.  
   
   
       12 . An input device according to  claim 8 , wherein the second display is transparent, at least in a large region.  
   
   
       13 . An input device according to  claim 8 , further comprising: 
 a control to drive the actuator, so that the touchscreen can be moved for confirmation of touching of an operating surface of a touchscreen.    
   
   
       14 . An input device according to  claim 13 , wherein the operating element can be displayed by the second display.  
   
   
       15 . An input device according to  claim 14 , wherein an explanation of the operating element or a context of the operating element can be displayed by the first display.  
   
   
       16 . An input device according to  claim 1 , wherein the input device is arranged in a vehicle.  
   
   
       17 . A method for operation of an input device comprising a first display for optical display of information, at least a second display arranged above the first display for optical display of information, and a touchscreen arranged above the second display for input of commands by touching an operating surface of the touchscreen, the method comprising the step of: 
 displaying an operating element and/or a warning message by the second display.    
   
   
       18 . A method according to  claim 17 , the method further comprising: 
 displaying an explanation of the operating element or a context of the operating element by means of the first display.    
   
   
       19 . A method according to  claim 17 , the method further comprising: 
 movement of the touchscreen to confirm touching of the operating surface of the touchscreen.
