A method is provided for operating a computer to analyze image evaluation data from electronic survey respondents to evaluate preferences related to two dimensional and three dimensional images. Data files, which include designated area data, image attributes, and survey respondent opinions for one or more images in an electronic survey, are received. A graphical user interface permits an operator to reformat the designated area data and set analysis parameters. Cluster analysis is performed on the data files to reduce the dimensionality of the designated area data and to classify areas of the survey images that generate positive and negative responses. The analysis produces coordinate data to map cluster classifications and for construction of a heat map. In association with descriptive statistical analysis, cluster score evaluation is performed to identify the clusters of interest. Respondent comments and results from the statistical analysis are linked to clusters of interest.
