Electronic device and method for shape recognition based on stroke analysis in electronic device

A method for shape recognition based on stroke analysis in an electronic device, the method comprising:

• identifying a size of a first stroke trajectory and a distance between a stroke start point of the first stroke trajectory and each one of points following the stroke start point on the first stroke trajectory at designated time intervals while displaying first stroke data of the first stroke trajectory on a display of the electronic device, based on an input of a first touch-move without a first touch-up after a first touch-down on the display;
• determining whether the size of the first stroke trajectory is greater than a specified size and a first distance between the stroke start point and a point among the points is less than a second distance between the stroke start point and a previous point of the point among the points;
• responsive to the determination, performing shape recognition for the first stroke trajectory;
• obtaining second stroke data corresponding to a recognized shape about the first stroke data, based on the shape recognition;
• and
• displaying the second stroke data on the display,
• wherein the second stroke data includes a first shape recognized by using the first stroke trajectory, and the first shape is one of a triangle shape, a rectangle shape, a circle shape, an ellipse shape, a trapezoid shape, a star shape, a straight line, or a curved line.

A non-transitory storage medium storing commands configured to, when executed by at least one processor, cause the at least one processor to perform at least one operation, the at least one operation comprising:

• identifying a size of a first stroke trajectory and a distance between a stroke start point of the first stroke trajectory and each one of points following the starting point on the first stroke trajectory at designated time intervals while displaying first stroke data of the first stroke trajectory on a display of an electronic device, based on an input of a first touch-move without a first touch-up after a first touch-down on the display;
• determining whether the size of the first stroke trajectory is greater than a specified size and a first distance between the stroke start point and a point among the points is less than a second distance between the stroke start point and a previous point of the point among the points;
• responsive to the determination, performing shape recognition for the first stroke trajectory;
• obtaining second stroke data corresponding to a recognized shape about the first stroke data, based on the shape recognition;
• and
• displaying the second stroke data on the display,
• wherein the second stroke data includes a first shape recognized by using the first stroke trajectory, and the first shape is one of a triangle shape, a rectangle shape, a circle shape, an ellipse shape, a trapezoid shape, a star shape, a straight line, or a curved line.
