可感知的最短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，响应延迟越短，应用程序即时响应的感觉就越大.众所周知，通常无法感觉到长达100ms的延迟.但是110ms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?

可以感知到的最短的应用程序响应延迟是什么?

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

我对任何可靠的证据，一般思想和观点都感兴趣.

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，出现字母的任何超过1/10秒(100毫秒)的延迟都会对生产率产生负面影响(例如，您本能地放慢速度，例如不太确定自己键入的正确性)，但是低于该水平的延迟生产率则基本保持不变.

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.

鉴于上述说明，小于100ms的延迟可能不是瞬时的，可能是可察觉的(例如，受过训练的棒球裁判员可以解决比100ms更近的两个事件的顺序)，但就影响生产率而言，它足够快，可以被视为立即做出反馈.即使延迟仍然相当快， 绝对可以接受100ms或更长的延迟.

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.

是为了视觉反馈已收到特定输入.然后，在所请求的操作中将有一个响应标准.如果单击表单按钮，则在100ms内获得该单击的视觉反馈(例如，该按钮显示沮丧"的外观)仍然是理想的，但是在此之后，您会期望发生其他事情.如果一秒钟之内没有发生任何变化(如其他人所说的那样)，您真的想知道是单击还是忽略了单击，因此标准是在某操作可能花费一秒钟以上时显示某种工作中..."指示符在显示清晰效果之前(例如，等待新窗口弹出).

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).
