网址导航界面链接按钮形式对视觉搜索的影响

为了探索网址导航界面中网站链接按钮的形式对用户认知以及绩效的影响。文中在对现有网址导航界面进行分析和设计的基础上，通过眼动追踪技术获取网站导航网页界面中视觉搜索的眼动数据，并按注视程度将其划分水平，结合网站链接按钮的另外两个设计要素(颜色和有无图标)作为实验材料的编码元素，设计实验并测试用户在上述网址导航原型上操作任务的绩效。结果表明，链接所处位置的注视水平和有无图标对链接按钮的搜索绩效有显著影响，更高的注视水平位置和有图标的编码形式能够促进网址导航的搜索绩效。鉴于链接按钮不同编码形式对网址导航界面搜索绩效的影响，网址导航界面设计可以采用更有区分度的链接按钮排列，以提高界面的可用性。

Effect of Link Button Form on Visual Search in Site Navigation Interface

In order to explore the influence of the form of the link button in the navigation interface on user''s cognition and performance, in this paper, based on the analysis of the existing site navigation interface, the eye-movement data of visual search in the site navigation interface are obtained through eye-tracking technology and divided into four levels according to the degree of fixation. The eye-movement data together with two design elements(colors and icons) of the site link button are factored as the coding element to test the user''s performance on the navigation prototype. The results show that the location of the link and the existence of the icons have a significant impact on the search performance of the link button, and a higher level of fixation and an icon can facilitate the search performance. In consideration of the influence of the different coding forms of the link button on the search performance of the web site navigation interface, a more distinguished link button arrangement can be used in site navigation interface design to improve the usability of the interface.
