Abstract: The present invention provides a visual representation of and unique, universal definition for a strike zone, said strike zone having a plurality of sub-zones. The strike zone representation allows for a signaling methodology to be developed in which a coach may discretely communicate signals during a game to his pitcher (ex.—baseball or softball pitcher) which request both a specific type and location for a particular pitch, based upon the game situation. Further, implementation of said signaling methodology based upon said strike zone representation allows for a performance factor to be determined for the pitcher. The performance factor may be determined based on results generated through use of the signaling methodology and may provide a universally-recognized gauge or measure of a pitcher's command of his pitches.

Abstract: A method for creating a graphical representation of a string of alphanumeric characters is disclosed. The method comprises determining a key position on a telephone keypad corresponding to each of the alphanumeric characters in the string, including a first key position for the first alphanumeric character, intermediate key positions for the intermediate alphanumeric characters, and a last key position for the last alphanumeric character. Then, a plurality of lines are successively generated from the first key position to each of the intermediate key positions to the last key position on the telephone keypad so as to create the graphical representation of the string of alphanumeric characters. Marking insignia are optionally generated to signify the beginning and end of the graphical representation. The method may be implemented by a computer.
