A new on-line essay test system that write the articles to manuscript paper which has two hundred squares for characters, look over and correct the manuscript paper in environment of on-line network like the real essay test is designed and implemented in this thesis. Using this system, a participant can write the articles to manuscript paper, a scorer look over and can correct the articles on manuscript paper directly. When looking over and correcting manuscript paper in this system, scorer can use a pen-mouse and a tablet. To reduce the network traffic, bitmap format of the manuscript paper is compressed to JPEG format before it is transmitted to server. The system is cost-effective and has lots of advantages in efficiency and usability. Furthermore, it is expected that the developed system can be used to improve the field of on-line subjective examinations as a counterproposal.
