Rule-based Approach for Personality Prediction Through Handwriting Analysis

Handwriting Analysis or Graphology is a scientific method of identifying, evaluating and understanding personality through the strokes and patterns revealed by handwriting. Handwriting reveals the true personality including emotional outlay, fears, honesty, defenses and over many other individual personality traits. It is not document examination, which involves the examination of a sample of handwriting to determine the author. Handwriting is often referred to as brain writing. Each personality trait is represented by a neurological brain pattern. Each neurological brain pattern produces a unique neuromuscular movement that is the same for every person who has that particular personality trait. When writing, these tiny movements occur unconsciously. Each written movement or stroke reveals a specific personality trait. Graphology is the science of identifying these strokes as they appear in handwriting and describe the corresponding personality trait. Handwriting has long been considered individualistic. Thus handwriting can be used effectively as a biometric. In this paper an attempt is made towards personality prediction of the writer through rule-based approach. The personality traits revealed by the baseline and the pen pressure, as found in an individual’s handwriting are explored in this paper. Two parameters, the baseline and the pen pressure, are the inputs to a rule-base which outputs the personality trait of the writer. The evaluation of the baseline is using the polygonalization method and the evaluation of the pen pressure utilizes the grey-level threshold value. The baseline and the pen pressure in one’s handwriting reveals a lot of accurate information about the writer. Hence this paper focuses on personality prediction using the baseline and the pen pressure. The authenticity of the methodology is validated by examination of multiple samples.
