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, in which

a1) a gesture of a user that is a movement which is executed by a hand or by both hands of the user on an existing example of the workpiece, is detected, or

a2) a gesture of a user that is a movement which is executed by a hand or by both hands of the user on an image of an existing example of the workpiece, is detected,

b) the detected gesture is automatically identified as a predefined gesture that represents a symbol, and

c) a measurement result of the measurement of a workpiece that is assigned to the gesture is automatically selected as a function of the identified gesture and displayed.

2. The method as claimed in claim 1, in which the symbol is a shape and/or 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 measurement result, and in which the gesture is identified as the symbol.

3. The method as claimed in claim 1, in which in the detection of the gesture at least one position at which the gesture is executed is detected, and a measurement result of the measurement of a workpiece is selected as a function of the identified gesture and the detected position of the gesture, and displayed.

4. The method as claimed in claim 3, in which in the case of the detection of the gesture in accordance with step a1) in claim 1, a position and alignment of the example of the workpiece is automatically detected, and in which the measurement result is selected as a function of a result of the detection of the position and alignment of the example and as a function of the detected position of the gesture.

5. The method as claimed in claim 1, in which, in addition, an alignment of the gesture is detected and the measurement result is also selected as a function of the alignment of the gesture.

6. The method as claimed in claim 1, in which the example of the workpiece is located 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 as claimed in claim 6, in which the example of the workpiece can be viewed from the viewing position through the image display device configured as a semitransparent display device.

8. The method as claimed in claim 1, in which an image of the example of the workpiece is generated by an image generation device and displayed on a screen, and in which the user executes the gesture on the screen.

9. The method as claimed in claim 1, in which a position and/or viewing direction of the user is automatically detected, and in which the selection of the measurement result is taken into account.

10. The method as claimed in claim 1, in which the selected measurement result is displayed in the correct position with reference to an image of the existing example, or in the correct position with reference to the example of the workpiece, which is arranged in the field of view of the user, that is to say the at least one measurement result is displayed, in particular, at a location or locations of an image display device at which the user respectively also sees a location of the example that corresponds to measured coordinates from which the measurement result was determined.

11. An arrangement for displaying results of a measurement of a workpiece, in which the arrangement has the following:

i. an interface for receiving the results and/or a memory for storing the results,

ii. a gesture detection device for detecting a gesture of a user that is a movement which is executed by a hand or by both hands of the user

on an existing example of the workpiece, or

on an image of an existing example of the workpiece,

iii. an identification device for identifying the gesture as a predefined gesture that represents a symbol, and

iv. a selection device for selecting a measurement result as a function of the identified gesture.

12. The arrangement as claimed in claim 11, in which the symbol is a shape and/or 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 measurement result, and in which the identification device is configured to identify the gesture as the symbol.

13. The arrangement as claimed in claim 11, in which the arrangement has a position detection device for detecting a position at which the gesture is executed.

14. The arrangement as claimed in claim 11, in which the arrangement has a determination device for determining a position and alignment of the example of the workpiece and which automatically determines the position and alignment of the example in the case of the execution of the gesture on the existing example of the workpiece, and in which the selection device is configured to select the measurement result as a function of a result of the determination of the position and alignment of the example and as a function of the detected position of the gesture.

15. The arrangement as claimed in claim 11, in which, in addition, the arrangement has an alignment detection device for detecting an alignment of the gesture, and in which the selection device is configured also to select the measurement result as a function of the detected alignment of the gesture.

16. The arrangement as claimed in claim 11, in which the example of the workpiece is located 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.

17. The arrangement as claimed in claim 16, in which the example of the workpiece can be viewed from the viewing position through the screen configured as a semitransparent screen.

18. The arrangement as claimed in claim 17, in which the arrangement has an image generation device for generating an image of the example of the workpiece and for displaying the image on a screen.

19. The arrangement as claimed in claim 11, in which the arrangement has a detection device for detecting a position and/or viewing direction of the user, and in which the selection device is configured to take account of the position and/or viewing direction of the user during selection of the measurement result.
