A special fountain pen and ordinary paper can be used to input human handwriting into a computer. The fountain pens tip would have stamped serration's in the horizontal and vertical directions which would indicate pen- paper motion to a vibration sensor mounted in the tip (nib) of the pen. The pens serration's would cause the nibs two sides to vibrate as the tip traveled across the paper. There would be one serration for up movement, one for down and one for right to left horizontal movement. The vibration sensor would detect pen paper movement in each half of the nib with both halves vibrating indicating horizontal or diagonal movement depending on the relative strengths of the signals. The signals would be amplified and coded to be transmitted wirelessly to a computer for further digital signal processing and handwriting analysis.
