Testing website usability by observing the motion of a user's face and hands

为了测试网站的可用性，可用性专家需要观察并倾听正在浏览网站的用户的意见。 因此，对于可用性专家和网站用户来说，测试都是耗时且繁重的。 为了有效且高效地进行可用性测试，我们开发了无需专家洞察即可自动判断网站是否可用的系统。该系统通过摄像头的图像和鼠标的信号来观察用户脸部和手部的运动。然后，它通过检测这些动作的临时暂停来评估网站的可用性。

For testing website usability, usability experts need to observe and listen to users who are navigating the website. Thus, the test is time-consuming and burdensome both for the usability experts and website users. To conduct the usability test in effective and efficient manner, we have developed the system that automatically judges whether a website is usable or not without experts' insight. The system observes the motion of a user's face and hands by images from a camera and signals from a mouse. Then, it evaluates the website usability by detecting the temporary suspension of those motions.
