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