ABSTRACT:
An electromagnetic digitizer tablet comprising an array of conductors having plural, spaced, similar active portions regularly and uniformly distributed throughout the active tablet region, together with additional structure to distinguish pointing device positions over the similar active portions. This arrangement reduces the number of individual conductors required. In a preferred arrangement, the active portions have a block S shape. As a further feature, novel algorithms are used to calculate the fine location of the pointing device.
