A quantitative color recognition measurement system using multimedia computer environment.
We developed a quantitative measurement system that tests the degree of dysgnosia resulting from Obsessive-Compulsive Disorder (OCD). The system outputs a stimulation word that had been set in advance using the voice output facility of the personal computer, then displays a color chart and waits for input from the subject. When the subject touches the CRT screen or clicks the mouse, the system records the response time and coordinates of input position. There were 30 stimulation words in the system. After 30 measurements of response time and input coordinates, the system outputs a results file that includes each response time and input coordinates. This test is easier and simpler than other psychological tests such as MMPI. The influence of the examiner can be reduced to the minimum with this system because it is a computer-based automatic measurement system. To use the computer system, an examiner can easily standardize the environment of the illumination, etc. Moreover, the system can save labor in testing, and can manage large amounts of data easily using the file management facility.
