【摘要】：本文以老年人的视觉选择性注意为主线,研究视觉注意相关理论以及老年人视觉注意特征,引出老年人视觉选择性注意,研究其认知流程、基本特征。分析在交互过程中,影响老年人视觉注意做出"选择"的因素。以网页交互界面为例,根据用户体验五要素中的结构层、框架层和表现层三个层各部分要素与视觉选择性注意之间的关系,提取交互界面中信息架构、页面布局、色彩、形状、材质界面交互要素,建立界面交互适老化机制。运用信息架构层级深度实验,获得适老化信息架构层级深度分析,运用交互要素选择实验,老年组和青年组进行对比,结合SPSS统计方法综合分析界面交互形式如何进行适老化设计。在感性评价的基础上,使用Tobii眼动仪纪录被测试者的眼动行为,并获得视觉注视时间和注视点等客观数据。在老年组和青年组测试结果对比分析的基础上,得出符合老年人视觉选择性注意交互要素特征,结合理论研究,得出基于视觉选择性注意的界面交互适老化设计原则。最后,运用总结的适老化设计原则对"老小孩"社区网站进行再设计,通过眼动实验验证结论可行性。
[Abstract]:This paper takes the visual selective attention of the elderly as the main line, studies the related theory of visual attention and the characteristics of the visual attention of the elderly, leads to the visual selective attention of the elderly, studies its cognitive process and basic characteristics. This paper analyzes the factors that affect the visual attention of the elderly in the process of interaction. Taking the interactive interface of web page as an example, according to the relationship between the three elements of the five elements of user experience and visual selective attention, the information structure, page layout, color and shape of the interactive interface are extracted. Material interface interaction elements, to establish interface interaction aging mechanism. The information architecture level depth experiment was used to obtain the level depth analysis of the information architecture for aging, and the interactive element selection experiment was used to compare the aged group and the young group. Combined with SPSS statistical method, this paper comprehensively analyzes how interface interaction can be designed for aging. On the basis of perceptual evaluation, Tobii eye movement instrument was used to record the eye movement behavior of the subjects, and objective data such as visual fixation time and fixation point were obtained. Based on the comparative analysis of the test results between the aged group and the young group, the characteristics of the interaction elements of visual selective attention in the elderly were obtained. Combined with the theoretical study, the design principle of the interface interaction suitable for aging based on the visual selective attention was obtained. Finally, the community website of "old children" was redesigned according to the principles of aging design, and the feasibility of the conclusion was verified by eye movement experiment.
