摘要
研究探讨智能手机动态画面与色彩对视力与辨色力的影响。实验因子为动态、色彩、时间等3项。动态因子包括静态、动态2种水平;色彩因子包括黑白色、相近色、丰富色3种水平;时间因子则分为操作手机游戏30 min与45 min 2种水平。实验结果包括视力与辨色力(以曼塞尔100色相检查器测量)于研究参与者操作前、后测量结果的差值。采用随机化完全区集设计,以参与者为区集,8位被試均需执行所有实验因子组合,每位被試需执行2×3×2=12次实验,以随机数随机排序12次实验的顺序。研究结果显示,手机画面为动态时,操作45 min的视力加深程度显著高于操作30 min的;故建议在动态画面时不要连续操作30 min以上;若为静态画面则可连续操作较长时间,但仍以45 min以下为宜。若需保持敏锐的辨色力时,亦建议不要连续操作30 min以上;静态黑白色画面的操作时间或许可以稍长,但达45 min时仍会对辨色力有较大的影响。
The aim of this research was to study the effects of movement and color of screen images on visual acuity and color discrimination of users. Experiment factors included movement,color and time period. The study had movement and time period both at two levels,i. e. static vs. dynamic and 30 minutes vs. 45 minutes,respectively. The color factor was conducted at three levels,i. e. black-and-white,proximal hue,and full hue. All 8 participants had to complete 2 × 3 × 2 = 12 test runs under random sequences. Measurements of visual acuity and color discrimination（ using Farnsworth Munsell 100 Hue Tester） were taken both before and after each trial. The variability between participants was controlled by the randomized complete block design（ RCBD）. The results showed that the visual acuity deterioration was significantly higher when participants operated straight 45 minutes than 30 minutes under dynamic images; and the visual acuity deterioration had no statistical difference between 45 and 30 minutes operating under static images. Color discrimination deterioration was significantly higher when participants operated straight 45 minutes than 30 minutes under all three color levels of images. The black-and-white was better than proximal and full hue under dynamic images.
