最短的可感知应用程序响应延迟是多少? [英] What is the shortest perceivable application response delay?

问题描述

在用户操作和应用程序响应之间总是会出现延迟.

A delay will always occur between a user action and an application response.

众所周知，响应延迟越低，应用程序瞬间响应的感觉就越大.众所周知，高达 100 毫秒的延迟通常是不可感知的.但是 110 毫秒的延迟呢?

It is well known that the lower the response delay, the greater the feeling of the application responding instantaneously. It is also commonly known that a delay of up to 100ms is generally not perceivable. But what about a delay of 110ms?

可以感知的最短应用响应延迟是多少?

What is the shortest application response delay that can be perceived?

我对任何确凿的证据、一般的想法和意见感兴趣.

I'm interested in any solid evidence, general thoughts and opinions.

推荐答案

我记得了解到的是，键入字母后出现超过 1/10 秒 (100 毫秒) 的任何延迟都会开始对生产力产生负面影响(例如，您本能地放慢了速度，不太确定您是否输入正确)，但低于该水平的延迟生产力基本上持平.

What I remember learning was that any latency of more than 1/10th of a second (100ms) for the appearance of letters after typing them begins to negatively impact productivity (you instinctively slow down, less sure you have typed correctly, for example), but that below that level of latency productivity is essentially flat.

鉴于这种描述，不到 100 毫秒的延迟可能会感知，因为它不是瞬时的(例如，训练有素的棒球裁判可能可以解析两个事件的顺序，甚至比 100 毫秒更近)，但它足够快，可以被视为对反馈的即时响应，就对生产力的影响而言.100 毫秒及以上的延迟绝对是可察觉的，即使它仍然相当快.

Given that description, it's possible that a latency of less than 100ms might be perceivable as not being instantaneous (for example, trained baseball umpires can probably resolve the order of two events even closer together than 100ms), but it is fast enough to be considered an immediate response for feedback, as far as effects on productivity. A latency of 100ms and greater is definitely perceivable, even if it's still reasonably fast.

这是针对已收到特定输入的视觉反馈.然后在请求的操作中会有一个响应标准.如果您单击表单按钮，在 100 毫秒内获得该单击的视觉反馈(例如，该按钮显示压抑"外观)仍然是理想的，但在此之后您预计会发生其他事情.如果一两秒内什么都没有发生，正如其他人所说，你真的想知道它是否接受了点击或忽略了它，因此当操作可能需要超过一秒钟时显示某种工作......"指示器的标准在显示清晰效果之前(例如，等待弹出新窗口).

That's for visual feedback that a specific input has been received. Then there'd be a standard of responsiveness in a requested operation. If you click on a form button, getting visual feedback of that click (eg. the button displays a "depressed" look) within 100ms is still ideal, but after that you expect something else to happen. If nothing happens within a second or two, as others have said, you really wonder if it took the click or ignored it, thus the standard of displaying some sort of "working..." indicator when an operation might take more than a second before showing a clear effect (eg. waiting for a new window to pop up).
