Abstract

A method for software control using a user-interactive display screen feature is disclosed that reduces stylus or other manipulations necessary to invoke software functionality from the display screen. According to the method, a graphical feature having a surface area is displayed on a touch-sensitive screen. The touch-sensitive screen is coupled to at least one processor and the graphical feature is generated by an operating system and uniquely associated with a particular software program by the operating system. To control software executing on the processor, a user-supplied writing on the surface area is received and the software is controlled responsive to the writing. In alternate embodiments, the method further controls data stored in a memory device responsive to the writing or further controls transmission of data from a radiation emitter, which may be coupled to voice and data networks.
