ABSTRACT:
A digitizer tablet uses sequenced wire addressing to derive time-related voltages correlated to the location of the addressed wires. The voltages are digitized, and an algorithm followed to determine by interpolation the exact position of a pointing device over the addressed wires. The algorithm employs a calculation based on determining the X-intercept of a straight line.
