Abstract

A displaying and operating device having a display unit and at least one proximity sensor, wherein a penetration of an object into at least one monitoring space can be detected by the proximity sensor, wherein at least one representation on the display unit is changed as a function of a penetrating object, wherein the displaying and operating device has a unit wherein a chronological sequence of receive signals from the proximity sensor is evaluated by the unit, wherein a constant receive signal is detected and stored within a predetermined time interval and, for subsequent operating, is ignored as a static receive signal of the display unit, wherein a change in the representation is carried out only if a subsequent receive signal exceeds the static receive signal by a predetermined value. Also disclosed is a method for operating a displaying and operating device.

Claims

1. A displaying and operating device comprising:

a display unit; and

at least one proximity sensor system, wherein penetration of an object into at least one monitoring space can be detected by the proximity sensor system,

wherein at least one representation on the display unit is altered depending on a penetrating object, and

wherein the displaying and operating device comprises a unit configured so that a temporal sequence of reception signals of the proximity sensor system is evaluated by the unit,

wherein a constant reception signal within a predefined time interval is detected and stored and for a subsequent control is ignored as a static reception signal of the display unit, and

wherein a change in the representation is carried out only if a subsequent reception signal exceeds the static reception signal by a predefined value.

2. The displaying and operating device of claim 1, wherein the previously detected static value is erased in the event of a decrease in the reception signal relative to a previously detected static reception signal by a predefined value.

3. The displaying and operating device of claim 1, wherein the proximity sensor system monitors exactly one monitoring space.

4. The displaying and operating device of claim 1, wherein the proximity sensor system is an IR proximity sensor system.

5. The displaying and operating device of claim 1, characterized in that wherein the proximity sensor system comprises a screen with an optical element.

6. The displaying and operating device of claim 4, wherein the optical element scatters emitted IR radiation into the monitoring space and guides received IR radiation to at least one receiving device.

7. The displaying and operating device of claim 4, wherein the proximity sensor system comprises at least one reference diode.

8. The displaying and operating device of claim 1, wherein the displaying and operating device is configured so that a change is made from a displaying representation to an operating representation on the display unit depending on a penetrating object.

9. A method for controlling a displaying and operating device, comprising a display unit and at least one proximity sensor system, the method comprising:

detecting penetration of an object into at least one monitoring space by the proximity sensor system;

altering at least one representation on the display unit depending on a penetrating object;

evaluating a temporal sequence of reception signals of the proximity sensor system by a unit;

detecting and storing a constant reception signal within a predefined time interval, wherein, for a subsequent control, the constant reception signal is ignored as a static reception signal of the display unit; and

carrying out a change in the representation only if a subsequent reception signal exceeds the static reception signal by a predefined value.

10. The method of claim 9, wherein the previously detected static value is erased in the event of a decrease in the reception signal relative to a previously detected static reception signal by a predefined value.

11. The method of claim 9, wherein the proximity sensor system monitors exactly one monitoring space.

12. The method of claim 9, wherein the proximity sensor system is an IR proximity sensor system comprising a screen with an optical element, wherein the optical element, scatters emitted IR radiation into the monitoring space and guides received IR radiation to at least one receiving device.

13. The method of claim 12, wherein the proximity sensor system comprises IR transmitting diodes, at least one IR receiving diode and a reference diode, wherein the emission characteristic of the IR transmitting diodes is deduced from the reception signals at the IR receiving diode on the basis of the emission of the reference diode.

14. The method of claim 9, wherein a change is made from a displaying representation to an operating representation on the display unit depending on a penetrating object.
