当使用移动终端浏览网页时，系统响应时间是可变的，并且比在PC上长得多。用户必须反复扫视显示器，以查看页面何时最终到达，尽管移动性要求最小注意力用户界面。我们对27名参与者进行了用户研究，以发现在移动的环境中视觉反馈停止到达用户的点。在这项研究中，我们研究了在几种不同的日常移动环境中，页面加载到手机与环境中的注意力部署，并将这些与实验室环境进行了比较。页面的第一部分通常在11秒内出现在屏幕上，但我们发现，用户的视觉注意力从移动的浏览器转移开，通常在移动的环境中的4到8秒之间。相比之下，在实验室条件下，对浏览器的持续注意力持续时间超过14秒。根据我们的研究结果，我们建议移动的应用程序提供多模态反馈的延迟超过四秒。
When browsing Web pages with a mobile device, the system response times are variable and much longer than on a PC. Users must repeatedly glance at the display to see when the page finally arrives, although mobility demands a Minimal Attention User Interface. We conducted a user study with 27 participants to discover the point at which visual feedback stops reaching the user in mobile context. In the study, we examined the deployment of attention during page loading to the phone vs. the environment in several different everyday mobility contexts, and compared these to the laboratory context. The first part of the page appeared on the screen typically in 11 seconds, but we found that the user's visual attention shifted away from the mobile browser usually between 4 and 8 seconds in the mobile context. In contrast, the continuous span of attention to the browser was more than 14 seconds in the laboratory condition. Based on our study results, we recommend mobile applications provide multimodal feedback for delays of more than four seconds.
