1. A method for automation of the interpretative analysis of a digital line drawn by a person on a digital electronic medium, the method comprising: a preliminary step for the acquisition of an archive of digital lines drawn by a plurality of persons; a preliminary step for the acquisition of graphic evaluations of each of said lines of said archive; a preliminary step for the acquisition of psychological evaluations of the persons who drew each of said lines of said archive; a preliminary step of providing a at least a supervised neural network and relative training to associate, for each of said lines of said archive, the graphic evaluations with the corresponding psychological evaluations; a step for the acquisition, through said digital medium, of a new digital line drawn by a person for the performance of its interpretative analysis, wherein said digital line comprises a scribble drawn on a sensitive area of said digital medium for a determined time and without detachment from the sensitive area, wherein the acquisition of said new digital line includes both the graphic result of the scribble and the dynamics with which it is executed, and wherein only the sex and age/age range of the person who has drawn said digital line is associated with said digital line; a step for the acquisition of the graphic evaluations of said new line, wherein said graphic evaluations of each of said lines of said archive comprise at least quantitative graphic evaluations established by an electronic processor interacting with said digital medium and formal/qualitative graphic evaluations; and an association step wherein said supervised neural network automatically associates the corresponding psychological evaluations with the graphic evaluations of said new line.
