LZ scale Components in LZ scale Components in Personality AssesmentPersonality Assesment
Thea Lewinson and Joseph Zubin provided a method to quantify the rhythm movement in writing.
The four dimensions that make up this rhythm scale are: Width, Height, Depth, and Form.
These four components determine the following dimensions of personality:
The rational
The social-emotional
The instinctual

Project GoalProject Goal
Problem: Manual
handwriting analysis is time consuming.
Aim: To Create software that allows a user to analyze handwriting samples using the L-Z analysis scales, with the aim of making the process faster and more objective. Example of Hitler’s handwriting

Program RequirementsProgram Requirements
Load a scanned handwritten document to the computer screen
Allow users to segment paragraphs, lines, words, and characters by using segmenting tools
Computer-assisted tools for computation of 1 or more LZ scales.
Push scale results into LZ Table and give user flexibility to override results with their own data

Computer-Assisted Analysis toolComputer-Assisted Analysis tool
The combination of a program’s automated analysis, with the input of an expert graphologist.
This approach has the advantage of significantly reducing the time required to analyze a given handwriting sample, but still keeps the control in the hands of the user.
This increase in power coupled with a higher level of objectivity, provides the user with a comprehensive tool to carry out handwriting analysis that is repeatable. 5

High Level GoalsHigh Level GoalsIn the creation of this application several key goals were defined.
Simplicity of design
A logically laid out dashboard that allows the user to organize and segment handwriting samples for analysis
A sequential checkpoint driven analysis tool to guide the user through the process of analysis.
Creation of a general management tool, for user profiles.

AnalysisAnalysis
One method used to measure a subset of LZ scales
Middle Line
Base Line
Top Line
Bottom Line
From those points regressive line approximations are derived and several scales could be calculated as a result, for example:
scale (g) - Height of Middle Zonescale (h) - Proportion of Upper, Middle Zone, Lower Zonescale (i) - Direction of Line

ConclusionConclusion
• We managed to implement an alpha version of the analysis software that automated two of the scales and assisted in the analysis of three others.
• We feel there is much work to be done. Many of the remaining scales can be quantified either through automation or computer assistance.
• The end goal should be to automate as much of the process as possible, through a pattern recognition classification system.
• Essentially more objectivity needs to be applied in the handwriting analysis process to make analysis repeatable.
