Multi-touch shape drawing

摘要

Multi-touch shape drawing. The use of multi-touch gesture detection improves the user interface experience associated with generating and modifying shapes. By associating unique multi-touch gestures with the generation of corresponding shapes, the accuracy and ease of use with which shapes can be generated can be improved. By associating multi-touch gestures with the modification of shapes, the ease of use with which shapes can be modified can be improved.

1. A method of an electronic device, the method comprising:
storing an association between each of a plurality of multi-touch motions and each of a plurality of geometric shapes available to be displayed on a display of the electronic device; detecting a first multi-touch motion of a multi-touch gesture applied to a touch-sensitive surface, wherein the first multi-touch motion is associated with each of a plurality of geometric shapes, the plurality of geometric shapes including some, but not all, of the plurality of geometric shapes available to be displayed; detecting a second multi-touch motion of the multi-touch gesture, the second multi-touch motion following the first multi-touch motion without intervening multi-touch motions; automatically selecting, from only the plurality of geometric shapes associated with the first multi-touch motion, a geometric shape to be displayed based on the detected first and second multi-touch motions of the multi-touch gesture without further user selection; and displaying the selected geometric shape on the display.
