Abstract

A gesture detection device detects a gesture of a user, which is a movement which is carried out by a hand or by both hands of the user on an existing example of the work piece, or on an image of an existing example of the work piece. An identification device identifies the gesture as a predefined gesture, which represents a symbol. A selection device selects a measurement result in dependence on the identified gesture. The measurement result can then be displayed or marked.

Claims

1. A method for displaying results of a measurement of a workpiece, which comprises the steps of:

performing one of;

detecting a gesture of a user being a movement executed by a hand or by both hands of the user on an existing example of the workpiece with a gesture detection device;

or

detecting a gesture of the user being a movement executed by the hand or by both of the hands of the user on an image of the existing example of the workpiece with the gesture detection device;

automatically identifying a detected gesture as a predefined gesture that represents a symbol with a computing device;

automatically selecting a measurement result of a measurement of the workpiece being assigned to the gesture in dependence on an identified gesture; and

displaying the measurement result.

2. The method according to claim 1, wherein the symbol is at least one of a shape symbol or a position symbol that defines which type of evaluation of measured coordinates of the workpiece or of an area of the workpiece is to be provided as the measurement result, and in which the gesture is identified as the symbol.

3. The method according to claim 1, wherein in the detection of the gesture, at least one position at which the gesture is executed is detected, and the measurement result of the measurement of the workpiece is selected in dependence on the identified gesture and a detected position of the gesture, and displayed.

4. The method according to claim 3, wherein the step of detecting the gesture of the user being the movement executed by the hand or by both hands of the user on the existing example of the workpiece, further comprises:

automatically detecting a position and an alignment of the existing example of the workpiece; and

selecting the measurement result in dependence on a result of a detection of the position and the alignment of the existing example and in dependence on the detected position of the gesture.

5. The method according to claim 1, which further comprises:

detecting an alignment of the gesture; and

selecting the measurement result in dependence on the alignment of the gesture.

6. The method according to claim 1, which further comprises disposing the existing example of the workpiece behind an image display device when seen from a viewing position of the user, and in which the user executes the gesture on the image display device.

7. The method according to claim 6, which further comprises viewing the existing example of the workpiece from a viewing position through the image display device configured as a semitransparent display device.

8. The method according to claim 1, which further comprises generating an image of the existing example of the workpiece via an image generation device and displaying the image on a screen, and in which the user executes the gesture on the screen.

9. The method according to claim 1, which further comprises automatically detecting at least one of a position direction or a viewing direction of the user, and in which the position direction detected or the viewing direction detected is taken into account in the selection of the measurement result.

10. The method according to claim 1, which further comprises displaying a selected measurement result in a correct position with reference to the image of the existing example, or in a correct position with reference to the existing example of the workpiece, which is disposed in a field of view of the user.

11. The method according to claim 10, which further comprises displaying the at least one measurement result at a location or locations of an image display device at which the user respectively also sees a location of the existing example that corresponds to measured coordinates from which the measurement result was determined.

12. A configuration for displaying results of a measurement of a workpiece, the configuration comprising:

at least one of;

an interface for receiving results;

a memory for storing the results;

a gesture detection device for detecting a gesture of a user being a movement executed by a hand or by both hands of the user on one of an existing example of the workpiece or an image of the existing example of the workpiece;

an identification device for identifying the gesture as a predefined gesture that represents a symbol; and

a selection device for selecting a measurement result in dependence on an identified gesture.

13. The configuration according to claim 12, wherein said symbol is least one of a shape symbol and a position symbol that defines which type of evaluation of measured coordinates of the workpiece or of an area of the workpiece is to be provided as the measurement result, and said identification device is configured to identify the gesture as the symbol.

14. The configuration according to claim 12, further comprising a position detection device for detecting a position at which the gesture is executed.

15. The configuration according to claim 12, further comprising a determination device for determining a position and alignment of the existing example of the workpiece and which automatically determines the position and alignment of the existing example in a case of an execution of the gesture on the existing example of the workpiece, and said selection device is configured to select the measurement result in dependence on a result of determination of the position and alignment of the existing example and in dependence on a detected position of the gesture.

16. The configuration according to claim 12, further comprising an alignment detection device for detecting an alignment of the gesture, and said selection device is configured also to select the measurement result in dependence on a detected alignment of the gesture.

17. The configuration according to claim 12, further comprising an image display device, the existing example of the workpiece is disposed behind said image display device when seen from a viewing position of the user, and in which the user executes the gesture on said image display device.

18. The configuration according to claim 17, wherein the existing example of the workpiece can be viewed from the viewing position through said image display device configured as a semitransparent screen.

19. The configuration according to claim 12, further comprising an image generation device for generating an image of the existing example of the workpiece and for displaying the image on a screen.

20. The configuration according to claim 12, further comprising a detection device for detecting at least one of a position or a viewing direction of the user, and said selection device is configured to take account of at least one of the position or the viewing direction of the user during selection of the measurement result.
