ABSTRACT:
A method is disclosed to operate a touch screen user interface. The method includes forming a stroke that encloses an area that contains at least a portion of at least one displayed object; and selecting the at least one displayed object. Forming the stroke may further include extending the stroke to a functional object, and activating the functional object with the at least one selected displayed object. If the stroke does not define an area that is totally enclosed by the stroke, the method may further include automatically continuing the stroke such that the area is totally enclosed by the stroke. In this case the stroke may be automatically continued by drawing a line that connects a stroke starting point to a stroke ending point, and by adding touch screen coordinates covered by the line to a list of touch screen coordinates that describe the stroke. If the stroke encloses an area that contains at least a portion of a plurality of displayed objects, each of the displayed objects is simultaneously selected.
