An application of 3D spiral visualization to the Uchida-Kraepelin psychodiagnostic test

Psychodiagnostic tests are used by hospitals, schools, companies, etc. Their effectiveness has been observed as tests that can reveal the internal and external status of the subject in detail. The data or the results of psychodiagnostic tests are very difficult to interpret by non-professionals. The resulting data is numerous, making it very difficult to read and interpret. The levels of understanding will vary depending on the cognitive ability and experience of the researcher or counselor interpreting the results. This study takes the results from psychodiagnostic tests and displays them as an easily understood 3D graph. The 3D graph is displayed as a spiral shape through `Processing'. The Uchida-Kraepelin psychodiagnostic test (U-K test) is used on over one million people each year by hospitals, schools, companies, etc. The purpose of this study is to use the 3D spiral to display the U-K test's calculation of workload and to emphasize the use of color on the 3D spiral visualization. A version with colors visible to colorblind people is used in conjunction with the 3D spiral visualization; the usage of color displays the U-K calculation of workload for non-colorblind people, while a colorblind-accessible version is used for colorblind people. The graphs produced in the study were given to professionals, non-professionals and colorblind people for evaluation.
