Talk:Keyboard matrix circuit

The SY77 has velocity sensitive keys and aftertouch. Using it as an exmaple without more explanation is probably unwise. There is no ribbon cable coming from the keyboard but two bundled cables. There are more wires in the matrix than the explanation provides for.

PC keyboard matrix

All PC keyboards (either USB or PS/2) internally also have a matrix of keys, similar to the description here. In fact a keyboard matrices are very common "staple building blocks" found in almost any design that uses many switches. I propose to change this article to a more generic article about the "keyboard matrix circuit". Unless there is already an article about this, with maybe a slightly different name?

Indeed. You might find inspiration in multiplexer, since keyboard matrices are effectively just specific implementations of that general concept. In fact, including "circuit" in the page name may be overly specific - keyboards on some electromechanical devices (e.g. teletypes) used mechanical components, not electrical circuits, to encode keypresses. Both "keyboard matrix" and "multiplexer" pages deserve to exist, but they ought to reference each other, and I can't swear some content shouldn't slosh from one page to the other.

I have an issue with the statement: "This process occurs so quickly that the performer is unaware of any delay.[1]". I found this page from the following page: https://danluu.com/keyboard-latency/ - which states "keyboards use a matrix that has to be scanned instead of having a wire per-key because it saves a few bucks, and most keyboards scan the matrix at such a slow rate that it induces human noticable delays". The author did a lot of research and experimentation, so I consider his results more accurate than Wikipedia's statement based on Dave Dribin's article which doesn't even mention "delay" or "unaware". However, I'm not sure how best to edit the statement... I would add the word "generally" (so it reads "This process occurs so quickly that the performer is generally unaware of any delay.[1]" with another citation being on "generally" to the danluu article, but I'm new to Wikipedia editing so I'd prefer someone's advice here. I think it's important to be more accurate here as in my experience I have noticed keyboard lag with newer keyboards (and I've been using keyboards since the early 80's) which has affected my performance (and irritation) and I think also affects other people's performance without them being aware (so that more awareness hopefully means improved keyboard efficiency and ultimately human happiness of course). — Preceding unsigned comment added by Wikidavefixer (talk • contribs) 04:14, 28 March 2018 (UTC)
