Device and method for identifying stacking and splitting of stenographic keystrokes

Abstract

A method, device, and computer program product for analyzing multiple keystrokes in an electronic stenographic recording machine having keys forming stenographic keystrokes when actuated includes sensing a depressed state of at least first and second keys and recording first and second depression times, sensing released states of the first and second keys and recording first and second release times, determining an elapsed depression-release time for each of the first and second stenographic keys, determining a percentage of chronological overlap of each of the elapsed depression-release times, and separating the first and second key depressions into separate stenographic keystrokes when the percentage of chronological overlap indicates a lack of correlation between the first and second key depressions.

What is claimed is: 
     
         1 . A method for analyzing multiple keystrokes in an electronic stenographic recording machine having keys forming stenographic keystrokes when actuated, which comprises:
 sensing a depressed state of a first stenographic key and recording a first depression time;   sensing a depressed state of a second stenographic key and recording a second depression time;   sensing a released state of the first stenographic key and recording a first release time;   sensing a released state of the second stenographic key and recording a second release time;   determining an elapsed depression-release time for each of the first and second stenographic keys;   determining a percentage of chronological overlap of each of the elapsed depression-release times; and   separating the first and second key depressions into separate stenographic keystrokes when the percentage of chronological overlap indicates a lack of correlation between the first and second key depressions.
