Abstract

User interfaces and processes to support a user during the operation of a touch-sensitive control unit. A presence of an input means, such as a finger of the user, is detected in a predefined first area in front of a button displayed on the control unit. In response to the detection a timer is started having a predetermined time segment. When the timer elapses, a secondary function in the control unit is executed relative to the button in which the input means is detected.

Claims

1. A method of operating a touch-sensitive operator control unit, comprising:

displaying a graphical symbol on the operator control unit, configured to execute a primary function associated with the graphical symbol;

detecting a presence of input means in a predefined first area in front of the operator control unit in an area of the displayed graphical symbol, wherein the predefined first area comprises an area parallel above a surface of the operator control unit;

executing a timer comprising a predetermined time segment in response to the detected presence of the input means;

executing the primary function to activate a function associated with the operator control unit if the presence of the input means is detected during a first portion of the predetermined time segment; and

executing a secondary function associated with the graphical symbol on the operating unit if the presence of the input means is still detected after a second portion of the predetermined time segment has expired, wherein the secondary function activates another function associated with the operator control unit.

2. The method of claim 1, further comprising stopping the timer after the presence of the input means in the predetermined first area is no longer detected.

3. The method of claim 1, further comprising:

executing the primary function if the presence of the input means in the predetermined first area is no longer detected after the first portion of the predetermined time segment has expired, and

wherein the secondary function is executed if the presence of the input means in the predetermined first area is no longer detected after the second portion of the predetermined time segment has expired, wherein the second portion is shorter than the first portion.

4. The method of claim 1, wherein the predefined first area comprises a distance of 1 mm to +100 mm from the surface of the control unit.

5. The method of claim 1, wherein an extension direction of the surface area is bounded by an area of the displayed graphical symbol.

6. The method of claim 1, wherein detecting the presence of input means in a predefined first area comprises detecting a crossover of the input means from a predefined second area in front of the operator control unit into the predefined first area.

7. The method of claim 1, further comprising generating an audio output after the predetermined time segment has expired.

8. The method of claim 1, the graphical symbol on the operator control unit comprises an element of a main display screen.

9. The method of claim 1, wherein the secondary function comprises at least one of:

an output of a navigation announcement;

a start of a context specific voice dialog;

an audio rendering of a text message;

a command for an input of a new navigation destination;

a command for executing music to be played;

a change of a content of the graphical symbol;

a start instruction for shifting the content of the button to another position of the operator control unit; and

a command for adapting a size of display of the content of the graphical symbol.

10. The method of claim 1, wherein the secondary function associated with the graphical symbol is assigned by a user.

11. A Human Machine Interface installed in a motor vehicle, comprising:

a touch-sensitive operator control unit configured to display a graphical symbol associated with a primary function on the operator control unit;

a detection device configured to detect a presence of input means in a predefined first area in front of the operator control unit in an area of the displayed graphical symbol, wherein the predefined first area comprises an area parallel above a surface of the operator control unit; and

a processing device, operatively coupled to the detection device and the operator control unit, wherein the processing device is configured to

execute a timer comprising a predetermined time segment in response to the detected presence of the input means,

execute the primary function to activate a function associated with the operator control unit if the presence of the input means is detected during a first portion of the predetermined time segment, and

execute a secondary function associated with the graphical symbol on the operating unit if the presence of the input means is still detected after a portion of the predetermined time segment has expired.

12. The Human Machine Interface of claim 11, wherein the processing device is configured to stop the timer after the presence of the input means in the predetermined first area is no longer detected.

13. The Human Machine Interface of claim 11, wherein the processing device is configured to

execute the primary function if the presence of the input means in the predetermined first area is no longer detected after the first portion of the predetermined time segment has expired, and

wherein the processing device is configured to execute the secondary function if the presence of the input means in the predetermined first area is no longer detected after the second portion of the predetermined time segment has expired, wherein the second portion is shorter than the first portion.

14. The Human Machine Interface of claim 11, wherein the predefined first area comprises a distance of 1 mm to +100 mm from the surface of the control unit.

15. The Human Machine Interface of claim 11, wherein an extension direction of the predefined first area from the surface area is bounded by an area of the displayed graphical symbol.

16. The Human Machine Interface of claim 11, wherein the detection device is configured to detect the presence of input means in a predefined first area comprises detecting a crossover of the input means from a predefined second area in front of the operator control unit into the predefined first area.

17. The Human Machine Interface of claim 11, wherein the processing device is configured to generate an audio output after the predetermined time segment has expired.

18. The Human Machine Interface of claim 11, further comprising a main display screen, wherein the graphical symbol on the operator control unit comprises an element of the main display screen.

19. The Human Machine Interface of claim 11, wherein the secondary function comprises at least one of:

an output of a navigation announcement;

a start of a context specific voice dialog;

an audio rendering of a text message;

a command for an input of a new navigation destination;

a command for executing music to be played;

a change of a content of the graphical symbol;

a start instruction for shifting the content of the button to another position of the operator control unit; and

a command for adapting a size of display of the content of the graphical symbol.

20. The Human Machine Interface of claim 11, wherein the secondary function associated with the graphical symbol is assigned by a user via the processing device.
