Abstract

A method for manually adjusting a numerical value displayed on a touch screen is provided. The method includes: displaying a multi-digit numerical value on the touch screen; selecting at least one digit of the displayed numerical value in response to sensing, by the touch screen, a first touch input operation; and adjusting a value of the at least one selected digit in response to sensing, by the touch screen, a second touch input operation differing from, and seamlessly following, the first touch input operation. A measurement device having corresponding features is provided, too. The method and the device respectively enable intuitive manual adjustment of the displayed numeric value without looking at the touch screen repeatedly and with a selectable rate of adjustment in value.

First claim

The invention claimed is:

1. A method of manually adjusting a numerical value displayed on a touch screen, comprising:
displaying a multi-digit numerical value on the touch screen,
selecting at least one digit of the displayed numerical value in response to sensing, by the touch screen, a first touch input operation, wherein the first touch input operation comprises maintaining and moving a touch contact in a parallel direction with respect to the displayed numerical value; and
adjusting a value of the at least one selected digit in response to sensing, by the touch screen, a second touch input operation differing from, and seamlessly following, the first touch input operation,
wherein the second touch input operation comprises moving the touch contact on the touch screen in a circular direction.

2. The method of claim 1 ,
wherein the first touch input operation comprises
establishing the touch contact in a screen plane of the touch screen within a predetermined distance from a respective center of the at least one digit.

3. The method of claim 2 ,
wherein the first touch input operation comprises
maintaining and moving the touch contact in the screen plane of the touch screen in the parallel direction with respect to a base line of the displayed numerical value.

4. The method of claim 2 ,
wherein the second touch input operation comprises
maintaining and moving the touch contact on the touch screen outside of the predetermined distance from a center of a most or least significant digit of the at least one selected digit.

5. The method of claim 2 ,
wherein the second touch input operation comprises
moving the touch contact on the touch screen in a perpendicular direction with respect to the base line of the displayed numerical value.

6. The method of claim 5 ,
wherein adjusting the value of the at least one selected digit comprises
adjusting the value of the at least one selected digit proportional to a distance magnitude or velocity magnitude along the direction of the second touch input operation.

7. The method of claim 1 ,
wherein the second touch input operation comprises mutually opposite orientations.

8. The method of claim 7 ,
wherein adjusting the value of the at least one selected digit comprises
increasing the value of the at least one selected digit in accordance with one of the mutually opposite orientations of the second touch input operation.

9. The method of claim 7 ,
wherein adjusting the value of the at least one selected digit comprises
decreasing the value of the at least one selected digit in accordance with the other one of the mutually opposite orientations of the second touch input operation.

10. The method of claim 1 ,
wherein adjusting the value of the at least one selected digit comprises
adjusting a value of a more significant digit of the at least one selected digit in response to a carry-over of the adjusting of the value of the at least one selected digit.

11. A measurement device, comprising
a touch screen configured to
display a multi-digit numerical value,
sense a first touch input operation, and
sense a second touch input operation; and

a processing unit configured to
select at least one digit of the displayed numerical value in response to the sensing of the first touch input operation, wherein the first touch input operation comprises maintaining and moving a touch contact in a parallel direction with respect to the displayed numerical value; and
adjust a value of the at least one selected digit in response to the sensing of the second touch input operation differing from, and seamlessly following, the first touch input operation wherein the second touch input operation comprises moving the touch contact on the touch screen in a circular direction.

12. The device of claim 11 , wherein the first touch input operation comprises
establishing the touch contact in a screen plane of the touch screen within a predetermined distance from a respective center of the at least one digit.

13. The device of claim 12 ,
wherein the first touch input operation comprises
maintaining and moving the touch contact in the screen plane of the touch screen in the parallel direction with respect to a base line of the displayed numerical value.

14. The device of claim 12 ,
wherein the second touch input operation comprises
maintaining and moving the touch contact on the touch screen outside of the predetermined distance from a center of a most or least significant digit of the at least one selected digit.

15. The device of claim 12 ,
wherein the second touch input operation comprises
moving the touch contact on the touch screen in a substantially perpendicular direction with respect to the base line of the displayed numerical value.

16. The device of claim 15 ,
wherein adjusting the value of the at least one selected digit comprises
adjusting the value of the at least one selected digit proportional to a distance magnitude or velocity magnitude along the direction of the second touch input operation.

17. The device of claim 11 ,
wherein the numerical value comprises a parameter of a measurement.

18. The device of claim 11 ,
wherein the numerical value comprises a parameter of the measurement device.
