As the application of projective technology, it has always been the dream of many researchers to realize the psychological evaluation of producers by analyzing sandplay works. Now most researchers use subjective analysis and statistical analysis to analyze the characteristics of sandplay works. However, without unified and standardized sandplay equipment, it is difficult to achieve horizontal comparison and communication among researchers, not to mention to achieve automatic analysis of sandplay works. Therefore, by reviewing and introducing the development of electronic sandplay equipment, the author tried to find a widely accepted and possible way for standardization of sandplay equipment used for automatic analysis. Finally, the author chose the scheme of 3D virtual sandplay equipment, named “AI Mental World”, and carried on the normalization and standardization transformation by adding many analytical points on this scheme. With these key points of analysis and the help of artificial intelligence algorithms, “AI Mental World” has initially realized automated analysis and intelligent description of sandplay works.
