The aim of this study was to evaluate working conditions using notebook personal computers, in order to prevent visual and musculoskeletal disorders. Four kinds of experiments of VDT (Visual Display Terminals) operations were carried out.The first experiment was to evaluate viewing conditions using with a notebook personal computer and a desktop personal computer. The display of the notebook personal computers would allow a comfortable downward gaze than the desktop personal computers from the vertical eye position viewpoint.The second experiment was to evaluate the work posture while using the notebook personal computers and desktop personal computers. Significant differences in both experimental conditions were seen with viewing distance, viewing angle and head angle. The characteristic features of the work posture using the notebook personal computers were a remarkably short viewing distance and a forward inclination of the head. The value of integrated electromyogram of the neck muscle was greater while using the notebook personal computers than when using the desktop personal computers.The third experiment was to evaluate the addition of a mechanism for adjustment of the height of the notebook personal computer. The height of the display, 90-100cm, would allow a comfortable downward gaze and correct posture. The work posture became a more upright head and neck position using this adjustable display.The final experiment was to consider how to use the flat panel display for various types VDT operations. The recommendation for comfortable VDT operation using the flat panel display, to adjust the display height for the each operator's height sitting down.

这项研究的目的是评估使用笔记本电脑的工作条件，以防止视力和肌肉骨骼疾病。进行了四种VDT（可视显示终端）操作实验，第一种实验是评价使用笔记本电脑和台式电脑的观看条件。从垂直眼位置的观点来看，笔记本型个人计算机的显示器比台式个人计算机允许舒适的向下注视。第二个实验是评价使用笔记本型个人计算机和台式个人计算机时的工作姿势。观察距离、观察角度和头部角度在两种实验条件下均存在显著差异。使用笔记本个人电脑的工作姿势的特征是一个非常短的观看距离和头部向前倾斜。使用笔记本电脑时，颈部肌肉的综合肌电图值比使用台式电脑时大。第三个实验是评价增加笔记本电脑高度调节机构的效果。显示屏的高度为90- 100厘米，可以提供舒适的向下凝视和正确的姿势。最后的实验是考虑如何使用平板显示器进行各种类型的VDT作业。建议使用平板显示器进行舒适的VDT操作，以根据每个操作员的坐姿高度调整显示器高度。
