Quantitative Evaluation System (QuESt) allows the examiner to analyze charts without the computer making an interpretation of truth or deception. QuESt graphically displays relative reaction strengths with color-coded bar graph or hodograph. It will analyze any question format, and offers selectable analysis times. Individual standardized charts may be viewed in a variety of time continuums, allowing the examiner a more detailed analysis or a global view. This computerized polygraph analysis software was developed by polygraph examiners for polygraph examiners.
