Abstract

A method for enlarging display regions on displays is provided. The method includes a definition of at least two enlargeable display regions, determining a touch screen signal, associating the touchscreen signal with an enlargeable display region to be enlarged and a display region-specific enlargement of the enlargeable display region to be enlarged.

Claims

1. A method for operating a measurement instrument including a touchscreen and an alternate operation device, the method comprising:

enlarging at least one display region on a display device of the measurement instrument;

defining at least two enlargeable display regions;

distinguishing a touchscreen touch from an operation of the alternate operation device for selecting one of the at least two enlargeable display regions;

evaluating the touchscreen touch to determine a touchscreen signal;

assigning a touchscreen signal obtained in this manner to an enlargeable display region to be enlarged; and

enlarging the enlargeable display region to be enlarged, wherein a type of enlargement is individually specified for each enlargeable display region;

wherein the type of enlargement is determined a priori dependent upon size and/or shape and/or orientation and/or position of the enlargeable display region to be enlarged;

wherein the type of enlargement includes a variation of geometric parameters of the enlargeable display region and a simultaneous variation of at least one of a font, a font size, a character spacing, and a line spacing of a text element of the enlargeable display region independently from one another, and independently from the variation of the geometric parameters of the enlargeable display region; and

wherein enlarging of the enlargeable display region is only triggered if the enlargeable display region is selected via the touchscreen touch as a virtual operating element instead of via the alternate operation device.

2. The method according to claim 1, wherein, within an enlargeable and/or enlarged display region, an enlarged display region and/or a further enlargeable display region is defined as a partial enlargeable region of the enlargeable and/or enlarged display region.

3. The method according to claim 2, wherein the type of enlargement in each case of an enlargeable display region is specified by several independent parameters.

4. The method according to claim 2, wherein the type of enlargement is specified dependent upon the content of the enlargeable display region to be enlarged.

5. The method according to claim 2, wherein the display region to be displayed in an enlarged manner contains at least one operating element and/or information unit.

6. The method according to claim 2, wherein a scroll bar is defined as an enlargeable display region.

7. The method according to claim 2, wherein a scroll bar is automatically opened on the display in the case of an enlargement of an enlargeable display region or of a partial enlargeable region in which the entire display region is not displayed simultaneously in an enlarged manner, so that a content of the enlarged display region can be scrolled.

8. The method according to claim 2, wherein the type of enlargement can be influenced by at least one parameter which is adjustable.

9. The method according to claim 1, wherein the type of enlargement in each case of an enlargeable display region is specified by several independent parameters.

10. The method according to claim 9, wherein the type of enlargement is specified dependent upon the content of the enlargeable display region to be enlarged.

11. The method according to claim 9, wherein the display region to be displayed in an enlarged manner contains at least one operating element and/or information unit.

12. The method according to claim 9, wherein a scroll bar is defined as an enlargeable display region.

13. The method according to claim 9, wherein a scroll bar is automatically opened on the display in the case of an enlargement of an enlargeable display region or of a partial enlargeable region in which the entire display region is not displayed simultaneously in an enlarged manner, so that a content of the enlarged display region can be scrolled.

14. The method according to claim 9, wherein the enlargement is reversed after the expiry of a given time or after a touch on the touchscreen provided for this purpose.

15. The method according to claim 1, wherein the type of enlargement is specified dependent upon the content of the enlargeable display region to be enlarged.

16. The method according to claim 1, wherein the display region to be displayed in an enlarged manner contains at least one operating element and/or information unit.

17. The method according to claim 1, wherein a scroll bar is defined as an enlargeable display region.

18. The method according to claim 1, wherein a scroll bar is automatically opened on the display in the case of an enlargement of an enlargeable display region or of a partial enlargeable region in which the entire display region is not displayed simultaneously in an enlarged manner, so that a content of the enlarged display region can be scrolled.

19. The method according to claim 1, wherein the type of enlargement can be influenced by at least one parameter which is adjustable.

20. The method according to claim 1, wherein the enlargement is reversed after the expiry of a given time or after a touch on the touchscreen provided for this purpose.
