Abstract

A display system includes a display for the graphic representation of changeable information, an operating unit for the control of the displayed information by a user, a proximity sensor which is arranged to detect an approach of the user to the operating unit, and a control unit. The control unit is coupled to the display, the operating unit and the proximity sensor. The control unit is arranged such that, as a function of an approach of the user to the operating unit, it alters the representation of the changeable information, such that a time rate of display change of the graphic representation of the changeable information is reduced.

Claims

1. A display method for a display system, the display system including a display adapted for graphic representation of changeable information and an operating unit adapted for control of displayed information by a user, comprising:

detecting an approach of the user to the operating unit; and

altering the graphic representation as a function of the detected approach to reduce a time rate of display change of the graphic representation;

wherein the display system includes a display system of a navigation system of a vehicle, the changeable information including a representation of a geographical map of an area surrounding the vehicle and position of the vehicle on the geographical map;

wherein if no approach of the user to the operating unit is detected, the vehicle is shown at a predetermined location on the display, and the display change include the representation of the geographical map as a function of a movement of the vehicle; and

wherein if an approach of the user below a predetermined distance to the operating unit is detected, the geographical map is shown unchanged on the display, and the display change includes a representation of the vehicle as a function of a movement of the vehicle.

2. The display method according to claim 1,

wherein the operating unit includes a touch-sensitive surface of the display, and the approach of the user to the surface of the display is detected by a proximity sensor.

3. The display method according to claim 1,

wherein if an approach of the user above the predetermined distance and below a further predetermined distance to the operating unit is detected, the display change includes the representation of the geographical map as a function of a movement of the vehicle, and the representation of the vehicle as a function of a movement of the vehicle.

4. An operating method for a navigation system of a vehicle, the navigation system including a display adapted for graphic representation of changeable information and an operating unit adapted for control of displayed information by a user, the changeable information including a representation of a geographical map of an area surrounding the vehicle and a position of the vehicle on the geographical map, comprising:

selecting a display mode with the aid of the operating unit from a group of display modes that includes a normal mode and a pause mode;

in the normal mode, showing the position of the vehicle in a predetermined location on the display and showing the geographical map variably on the display as a function of a movement of the vehicle;

in the pause mode, showing the geographical map unchanged on the display from the fixed representation centered on the location of the vehicle at the time the pause mode was selected and showing the position of the vehicle variably on the display as a function of a movement of the vehicle;

detecting an approach of the user to the operating unit; and

altering the graphic representation as a function of the detected approach to reduce a time rate of display change of the graphic representation.

5. The operating method according to claim 4,

wherein the group of display modes further includes a return-travel mode, the method further comprising, in the return-travel mode, showing the geographical map as a film sequence as a function of a travel path previously covered by the vehicle.

6. The operating method according to claim 4,

wherein the group of display modes further includes a pre-travel mode, the method further comprising, in the pre-travel mode, showing the geographical map as a film sequence as a function of a planned travel path of the vehicle.

7. The operating method according to claim 4,

wherein the operating unit includes a touch-sensitive surface of the display.

8. A display system, comprising:

a display adapted for graphic representation of changeable information;

an operating unit adapted for control of displayed information by a user;

a proximity sensor adapted to detect an approach of the user to the operating unit; and

a control unit coupled to the display, the operating unit, and the proximity sensor, the control unit adapted to alter, as a function of an approach of the user to the operating unit, the representation of the changeable information to reduce a time rate of display change of the graphic representation of the changeable information;

wherein the display system includes a display system of a navigation system of a vehicle, the changeable information including a representation of a geographical map of an area surrounding the vehicle and position of the vehicle on the geographical map;

wherein if no approach of the user to the operating unit is detected, the vehicle is shown at a predetermined location on the display, and the display change include the representation of the geographical map as a function of a movement of the vehicle; and

wherein if an approach of the user below a predetermined distance to the operating unit is detected, the geographical map is shown unchanged on the display, and the display change includes a representation of the vehicle as a function of a movement of the vehicle.

9. The display system according to claim 8,

wherein the display system is adapted to perform a method including:

detecting an approach of the user to the operating unit; and

altering the graphic representation as a function of the detected approach to reduce the time rate of display change of the graphic representation.
