Abstract
Facilities Management Control System （FMCS）is the most important system for the semiconductor industrial safety, because any unexpected accident may result in the deadly damage. Facilities Management Control System（FMCS） is a system that includes production system, electronic database and environment monitor. The FMCS is monitored by the video display, which assists supervisor on the situation detection, checking and evaluation. Visual and auditory channels are the major medium for information transmission and communication. The auditory warning display is suitable for most monitoring tasks, especially for the heavy loading and complex working environment. Brief verbal display is helpful for the warning communication and human responding. Too long time operation, visual or auditory fatigue often causes information lost and mistakes in the VDT working station. Therefore, the designs of the human-system interface will affect judgment and response time.The purpose of this paper is to study the warning display and supervisor’s response. Additionally, this paper also includes the principle of human factor design and environment factor in order to improve the effects of visual and auditory displays, control method of exist system. By the way, the paper use the principle of direct manipulation to setup a hotkey device to make every item to be controlled immediately. It will enhance personal performance and increase the function of this system. The first step of this paper is to evaluate the visual and auditory warning displays of the current system. After evaluation, two stages of the experiment were designed to find out the optimal video display and control method. The independent variables include auditory warning display, control method and item arrangement. The dependent variables include reaction time and number of error. The results indicated that new design of auditory warning display was effective on the primary monitoring performance. Visual plus audio warning is the best way for high mental workload and complex condition. Applying the principle of direct manipulation to setup a hotkey and wireless control panel as the control device can improve supervisor’s detection ability, response speed and accuracy to a warning signal. According to the experimental results and supervisor’s demand, some design suggestions of human interface and future research directions are proposed. It is expected this paper can be applied to design of warning signal display for other similar monitory systems.
