摘要
为提升中老年人数字阅读体验,根据认知负荷与用户体验测量理论,采用正交实验设计方法,以及主观测量与眼动数据相结合的技术路线,以可用性、舒适度、阅读速度、认知负荷、眨眼率、瞳孔面积为评价指标,评价数字阅读文字设计。结果发现影响中老年人数字移动阅读的最优体验的因素重要性排序是字号、字间距和行间距。在字号是17像素,字间距加宽0.5磅,1.2倍行间距的实验条件下,获得了最优体验和较低的认知负荷,此外阅读体验的可用性与舒适性显著正相关,与认知负荷显著负相关。
This article aims to improve the digital reading experience of older people.Based on the cognitive load theory and user experience measurement,an orthogonal experiment design was conducted.Subjective measurement and eye movement data were used to assess the digital reading experience of older people.The usability,comfort,reading speed,cognitive load,blink rate,pupil area were used to evaluate the text design of digital reading materials.It was found that the key factors that influence the optimal experience of digital reading for older people were font size,word spacing and line spacing.Under the experimental conditions of the font size 17px,0.5pt extra word spacing and 1.2-line spacing,the optimal experience was obtained with lower cognitive load.In addition,the usability of the reading experience was significantly positively correlated with the subjective perception of comfort,but negatively correlated with cognitive loads.
