This is a terrific writeup about the latencies of text editors. Now the next step is to research the effects of latency on cognitive strain, typing accuracy, and typing speed.<p>Without that, the latency numbers themselves don&#x27;t mean much. Some 100 ms latencies are readily noticeable (video game input), others are not (pushbutton responses).<p>This paper (<a href="http:&#x2F;&#x2F;www.tandfonline.com&#x2F;doi&#x2F;abs&#x2F;10.1080&#x2F;00140137608931531" rel="nofollow">http:&#x2F;&#x2F;www.tandfonline.com&#x2F;doi&#x2F;abs&#x2F;10.1080&#x2F;00140137608931531</a>) seems to suggest that typing speed does decrease at higher delays, but recovers after a short time. I can&#x27;t access this journal though, so I don&#x27;t know what kinds of delays were tried, and I don&#x27;t know how long the recovery time actually is.
