Abstract

A method and a system for processing gestures to cause computation of measurements of an angle or a segment using a touch screen are disclosed. The system includes a processor, a touch screen coupled to the processor, and a gesture module coupled to the processor for executing a gesturing method. The method includes determining a gesture shape. For example, when the gesture shape is an arc or a line between two touching lines, the method calculates the measurement of the angle between the touching lines and behind the gestured line or arc. When the gesture is a line crossing a segment, the method calculates the measurement from the beginning of the segment to the end of the segment. The method further displays the calculated measurement of at least one of the angle or the segment.

Claims

1. A method for initiating a measurement calculation of one or more lines displayed on a touch screen display of a processor-based system, the method comprising:

receiving a gesture input using the touch screen display;

using a processor of the processor-based system to determine a gesture shape indicated by the gesture input;

using the processor to determine the number of lines of the one or more lines that are selected by the gesture input, wherein each selected line of the one or more lines is indicated by the gesture shape touching the selected line, wherein touching the selected line comprises intersecting the selected line;

when the number of selected lines is one, using the processor to identify a beginning point and an end point of the one selected line, calculate a measurement of length between the beginning point and the end point of the one selected line, and display the calculated measurement of the length on the touch screen display; and

when the number of selected lines is two, using the processor to identify an angle formed between the two selected lines, calculate an angle measurement of the angle, and display the calculated angle measurement on the touch screen display.

2. The method of claim 1, wherein, when the number of selected lines is two, the two selected lines touch at a common point.

3. The method of claim 1, wherein, when the number of selected lines is two, the two selected lines do not touch each other.

4. The method of claim 1, wherein, when the number of selected lines is two, the calculated angle measurement is displayed on the touch screen display in close proximity to the two selected lines of the displayed one or more lines.

5. The method of claim 1, wherein, when the number of selected lines is one, the calculated measurement of length is displayed on the touch screen display in close proximity to the one selected line of the displayed one or more lines.

6. The method of claim 1, wherein the one or more lines is displayed on the touch screen display when the gesture input is received.

7. The method of claim 1, wherein the gesture shape is an arc.

8. The method of claim 1, wherein the gesture shape is a line.

9. A system comprising:

a touch screen display configured to display one or more lines and having a touch screen configured to receive a gesture input;

a processor communicatively coupled to the touch screen, the processor being configured to process a received gesture input; and

a memory communicatively coupled to the processor and storing program instructions that, when executed by the processor, cause the processor to;

determine a gesture shape indicated by the received gesture input;

determine the number of lines of the displayed one or more lines that are selected by the gesture input, wherein each selected line of the geometric element is indicated by the gesture shape touching the selected line, wherein touching the selected line comprises intersecting the selected line;

when the number of selected lines is one, identify a beginning point and an end point of the one selected line, calculate a length measurement between the beginning point and the end point of the one selected line, and display the calculated measurement of the length on the touch screen display; and

when the number of selected lines is two, using the processor to identify an angle formed between the two selected lines, calculate an angle measurement of the angle, and display the calculated angle measurement on the touch screen display.

10. The system of claim 9, wherein, when the number of selected lines is two, the two selected lines touch at a common point.

11. The system of claim 9, wherein, when the number of selected lines is two, the two selected lines do not touch each other.

12. The system of claim 9, wherein, when the number of selected lines is two, the calculated angle measurement is displayed on the touch screen display in close proximity to the two selected lines of the displayed one or more lines.

13. The system of claim 9, wherein, when the number of selected lines is one, the calculated length measurement is displayed on the touch screen display in close proximity to the one selected line of the displayed one or more lines.

14. The system of claim 9, wherein the one or more lines is displayed on the touch screen display when the gesture input is received.

15. The system of claim 9, wherein the gesture shape is an arc.

16. The system of claim 9, wherein the gesture shape is a line.
