伴随今日荧幕技术进步,大型荧幕已经成为一种流行趋势。本研究希望得知大型荧幕对视觉、工作绩效之影响,并了解肌肉不适之情形。比较四种荧幕尺寸(15、17、19和21英吋)以主观评量、工作绩效、视觉压力、颈肩姿势与肌肉活动之影响。由主观评量得知,19吋工作绩效是最好的,荧幕大小对视觉表面积的影响是显著的,在工作超过一小时候,眨眼率与视觉疲劳也大幅增加,颈肩姿势对荧幕大小无显著的,最后,荧幕大小对平均作业时间有显著的影响。结论,19英吋萤幕是我们推荐适用于长时间的作业平台。
With today’s screen technology advances, large-screen has become a trend. This study wanted to know the impact of large screens on visual and work performance, as well as understanding the conditions of muscle discomfort. The four screen sizes (15, 17, 19 and 21 inches) were compared for subjective assessment, job performance, visual stress, neck and shoulder position, and muscle activity. From the subjective evaluation, 19-inch work performance is the best, the screen size of the visual surface area of the impact is significant, more than a hour in the work, blink rate and visual fatigue also increased significantly, the position of the shoulder and shoulders on the screen size No significant, and finally, the screen size has a significant impact on average job time. In conclusion, the 19-inch screen is our recommended platform for a long time.
