Abstract

Disclosed is method, system, and program for defining and administering a test to determine human perceptions of observable samples, such as printed text or images, sounds, motion pictures, etc. based on multiple factors. A displayable test building window includes input fields to receive input on at least one observable sample set according the multidimensional scaling experiment. Generated in a data gathering window is at least one perception input field for each observable sample set. The observer is capable of entering perception information in each input field concerning the observable samples. Observer perception input on the observable samples is received and stored. Statistical analysis is then performed on the entered perception input. A report is generated displaying the results of the multidimensional scaling calculations in the form of plots.

Claims

1. A program for comparing multiple factors using multidimensional scaling analysis, the program comprising computer usable media including at least one computer program embedded therein that causes the computer to perform:

generating at least one set of samples, where each sample in the set is created by a print algorithm combining a number of factors;

for each set, collecting data on observable relative differences between samples in the set;

performing multidimensional statistical analysis on the collected data; and

displaying results of the statistical analysis as plots.

2. The program of claim 1 that causes the computer to further perform:

displaying a test building window including input fields to receive input on the at least one set of samples;

generating a data gathering window including at least one perception input field for each observable set, wherein an observer is capable of entering perception information in each input field concerning the observable set;

receiving observer perception input on the observable set; and

storing the observer entered perception input.

3. The program of claim 2, wherein the observable sample is embodied in a medium that is a member of the set of mediums comprising:

images, text, sound, and motion pictures.

4. The program of claim 1 that causes the computer to further perform:

interpreting the plots to determine human perceptions to variations of factors.

5. The program of claim 1 that causes the computer to further perform:

determining an optimal number of factors to be compared for interpretation of the collected data; and

generating plots comparing two factors at a time.

6. The program of claim 1 that causes the computer to further perform:

performing rotational analysis on the plots and generating a report based on the collected data.

7. The program of claim 1, wherein the algorithm comprises a printing algorithm to control a printer to print the observable sample on paper.

8. The program of claim 7, wherein the factors in the printing algorithm are a member of a set of factors comprising half-tone screen, sharpening, smoothing, and resolutions.
