多年来，软件工程师一直被告知，应用程序必须在100毫秒内响应用户事件，才能看起来是即时的，但这种假设从未经过系统的测试。在这项研究中，我们试图建立阈值检测的变化，在图形用户界面中使用自适应跟踪。对于键盘交互，受试者没有注意到大约150毫秒的延迟。相比之下，对于老鼠的互动，受试者没有注意到长达195毫秒的延迟。鉴于这些发现，显然需要进一步的研究来确定应用程序响应性的下限，以便软件和操作系统工程师可以更精确地调整其系统的交互式实时响应性。
For years, software engineers have been told that applications must respond to user events within 100 milliseconds to seem instantaneous, yet this assumption has never been systematically tested. In this research, we attempt to establish thresholds of detection for changes in a graphical user interface using adaptive tracking. For keyboard interactions, subjects did not notice delays of approximately 150 milliseconds. In contrast, for mouse interactions, subjects did not notice delays of up to 195 milliseconds. Given these findings, further research is clearly needed to firmly establish lower bounds on application responsiveness so that software and operating system engineers can more precisely tune the interactive real-time responsiveness of their systems.
