23. A Trail Making Test (TMT) test result display method that enables execution of a TMT test on a display and displays a test result on the display, the TMT test result display method allowing a computer to carry out the following steps which includes:
a test image generation display step for electronically generating a TMT test image which is formed by setting transit points at a plurality of positions on a coordinate plane, said step also including displaying TMT test image on the display;
a test data acquisition step for acquiring time-dependent data of a drawing trajectory drawn by a test subject moving a contact part in contact with the display surface of the TMT test image and tracing the transit points in a predetermined order; and
a data processing display step for processing the data acquired by the test data acquisition step and for displaying the processing result as the test result on the display the test data acquisition step includes: i) a coordinate data acquisition step for acquiring coordinate data corresponding to the position of the contact part on the coordinate plane in accordance with a detection signal from a sensor that detects the contact of the contact part with the display surface of the TMT test image; ii) time data acquisition step for acquiring time data associated with the acquisition time of each coordinate data by using a timer, and
the data processing display step includes: i) a calculation step for calculating a predetermined test value based on the coordinate data and the time data in the contact part; ii) an image generation step that generates characteristic images each of which displays a time-dependent change of a test value calculated by the calculation step in association with the position of transit point, the characteristic images corresponding to each respective region formed by dividing the coordinate plane into a plurality of regions; and iii) an image output display step that outputs a processed image including the characteristic image generated by the image generation step and displays the image on the display.
