ARCHITECTURE FOR THE ACQUISITION OF A GRAPHOMETRIC AND ELECTRONIC FIRM MOVED WITH A HIGH LEVEL OF PHYSICAL AND LOGICA L SECURITY ELECTRONIC TABLE

摘要

Electronic and computer tablet (2) system comprises an electromagnetic digitizer for acquiring the x, y and z coordinates of an electronic pen (3). Special computer programs are used to acquire the coordinates by reconstructing the values of acceleration, speed, radius of curvature, acceleration and deceleration, pressure and movement in the air of the pen. It is possible to switch the entering of the digitalized data from the mouse to the graphometric mode. The system also comprises a color display connected by a USB connection (5) for visualizing the signed PDF document or other types of document format.
