DIGITIZER TABLET WITH REGIONAL ERROR CORRECTION |
摘要 |
A digitizer tablet exhibiting improved regional error correction comprises evaluation of two linear equations to correct the generated raw coordinates. The equations contain certain constants unique to tablet regions (I-IX) exhibiting similar error patterns. These constants are empirically determined and stored for use in the evaluations.
