ABSTRACT:
Transparent tablet for evaluation of motor responses furnishes the coordinates of the contact points of at least one conductive probe tip on tablet. The tablet is overlaid on its outer face by a resistive transparent film, such as tin dioxide. By the provision of a current-generating device in first and in second directions, voltage gradients are set up along the resistive transparent film in the first and second directions. The voltages picked up by the conductive probe tip at the point of contact are proportional to the distance of the point to the edges of the tablet along each of the directions. The numerical values of the point coordinates are furnished by the conversion to digital form, by an A/D converter, of the voltage.
