The researcher added the functions of document management and picture annotation to Web-based CAID forums. The method of this research includes surveys on current situation, building CAID forums for experiments and comparing the interfaces of them. The researcher first selected representative forums for investigation and conducted surveys on users’ needs through questionnaires and interviews. According to the results of surveys, the researcher added the functions of document management and picture annotation using two operation modes, i.e., “a single window” and “two windows,” for CAID forums. Experiments in this study, including tasks for document management and picture annotation, were independent to each other. The objective evaluations in experiments included completion time, the completion rate of storing topics and the completion rate of searching specific topics. The subjective evaluations in experiments included preference, convenience, satisfaction and fitness of users' needs.
There were three tasks for document management. In the tasks of “Add folders and store topics” and “Check folders and store topics,” completion time of two windows was less than that of a single window. However, in “Search answers and topic ID number,” completion time of a single window was less than that of two windows. When there are many topics in the forum, users always need search task. Therefore, completion time of “Search” is important than “Add,” “Check,” and “Store.” Besides, participants prefer to use a single window to manage their document. Therefore, a single window is better than two windows in document management mode.
There were two tasks for picture annotation. In “Post new topics” task, completion time of two windows was less than that of a single window. In the task of “Reply topics,” there was no significant effect on completion time. In addition, participants prefer using a single window to manage their document. Since users have little chance, perhaps even no, to post many topics within a time limit, the completion time is not as important as their preferences. Therefore, single-window mode is still good enough for picture annotation.
According to these discussions, this research suggests the CAID forum designers must integrate user interfaces of document management and picture annotation in a single window.
