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 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 depressed state of a third stenographic key and recording a third depression time, sensing a released state of the first key and recording a first release time, sensing a released state of the second key and recording a second release time, sensing a released state of the third key and recording a third release time, sorting the first, second, and third depression times based on a chronological order of occurrence, determining, within the plurality of sorted depression times, a pair of chronologically adjacent depression times with a greatest chronological variation therebetween, determining an elapsed depression-release time for each one of the determined pair of adjacent depression times, determining a percentage of chronological overlap of the elapsed depression-release times, comparing the percentage of chronological overlap to a predefined value, and separating the first, second, and third key depressions into two separate stenographic keystrokes when the percentage of chronological overlap is less than the predefined value.
