Abstract

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

Claims

1. A gesturing method for processing gestures to cause computation of measurements of an angle or a segment using a touch screen, comprising:

determining a gesture shape,

when the gesture shape is an arc between two touching lines, calculating the angle between the touching lines behind the gestured line or arc;

when the gesture is a line crossing a segment, calculating the measurement from the beginning of the segment to the end of the segment; and

displaying at least one of the calculated angle and the calculated measurement of the segment.

2. A gesture system, comprising:

a processor;

a touch screen coupled to the processor;

a gesture module coupled to the processor for executing a gesturing method, the method comprises;

determining a gesture shape,

when the gesture shape is an arc between two touching lines, calculating the angle between the touching lines behind the gestured line or arc;

when the gesture is a line crossing a segment, calculating the measurement from the beginning of the segment to the end of the segment; and

displaying at least one of the calculated angle and the calculated measurement of the segment.
