Definition

A computer aided device equipped with a digitizing table and a CURSOR for digitally capturing graphical data (pictures, charts), usually based on vector-techniques (as opposed to a SCANNER). The digitizing table consists of a gridded electrical network under the table's surface which allows an automatic computation of the planar x/y coordinates of a cursor's position. Lines are sequentially scanned by moving the cursor along the position and identifying the appropriate symbol on a menu.
