message: So there are no clear WPMs.  Are there any opinions by notable users about speed relative to regular keyboards? - Omegatron 22:53, May 8, 2005 (UTC)
:Omegatron: With Spiffchorder, Greg Priest-Dorman typed 55wpm even after months of using another chorder. "So, I put my seven key chorder back on (after not using it all those same months) and did 55 wpm. " http://wiki.cs.vassar.edu/people/priestdo/wearables/top OjM (talk) 12:22, 21 July 2009 (UTC)
replies: text: For example, each finger might control one key which corresponds to one bit in a byte, so that one to eight fingers can enter any character in the ASCII set if the user can remember the binary codes. 
Aren't there only 7 bits in ASCII?—Trevor Caira 13:12, 28 July 2005 (UTC)

message: I redirected Chordon here, but I felt some of the text might be useful to integrate here:
Chordon is a concept used with some chording keyboards (e.g. GKOS). It is a string of chords where common keys between two consecutive characters (i.e. chords) are not released.
Often, the detection of a combination of keys, representing a character to be entered on a chording keyboard, requires that all keys must be released before and after the chord (= combination of keys). This somewhat slows down the typing and may easily lead to wrong or missing characters because the gaps between chords may disappear while typing fast.
There are several methods to overcome this. One is to decide on the character when a key (any key) of a chord is released first time. This greatly improves the reliability. Another method is the Chordon technique where a more complicated detection of key combinations is used, allowing overlapping of chords during complete words and not requiring the release of keys that are common to consecutive characters.
The Chordon detection algorithm can not rely on absolute lengths of key presses because typing speeds can vary a lot. Instead, the average length of a single character must be estimated and the structure of the string of overlapping chords (e.g. a word or a syllable) is interpreted as a whole.
The advantage with Chordon detection is that overlapping is fully allowed (less errors, all characters are still detected) and, because there is no need to release all keys between characters, typing becomes partly parallel resulting in higher possible typing speeds.

I do not understand the Chordon technique. It is not fully described above.  However the read-chord-on-first-release algorithm described by Bequaert et al. in expired US patent 4042777 does provide excellent character recognition in the presence of chord overlap.  The Bequaert algorithm toggles between two modes, chord forming mode and chord releasing mode. The first key press puts the keyboard into forming mode, The keyboard remains in forming mode through any additional key presses. The first key release puts the keyboard into releasing mode where it remains until any new key press returns it to forming mode.  The intended chord is taken to be the one existing just before the entry into releasing mode, i.e., just before the first key release.  A little thought shows that any keys needed by adjacent characters need not be released. The resulting feel of the keyboard is very natural and it's simple to program. Bequaert's method is what I use in the Chordite. --- John McKown  —Preceding unsigned comment added by 24.251.186.204 (talk) 21:57, 27 February 2011 (UTC)

message: "Doug Engelbart, inventor of the computer mouse, may have invented chord keyboards."
...but then we have already said that the stenotype machine is a chording keyboard and that it
was invented in 1858.  So I don't think Doug gets the credit and I'm removing this statement. SteveBaker 16:07, 14 March 2006 (UTC)

message: I've redirected Chorded keyset here. That page included this text, which was added yesterday:
: A five key chord keyset was standard issue with the Xerox Alto in the early days at Xerox PARC. The advantage was that multiple keys could be struck at the same time, allowing 31 differnet combinations. There was an editer, ugh, which catered to use with this keyset. It allowed one to use the mouse with one hand, and the keyset with the other to input text. The chord keyset was mapped to allow the letters plus some escapes for use with upper case and numbers and other characters. There were folks who could enter text as fast with this as with a standard keyboard, and they had simultaneous mouse capability without moving their hands.
: The chord keyset was also heavily used in playing Maze War, where the keys were mapped to the common movement patterns.
I'd like to see a reference for this-- everything I've read says PARC only used the mouse, not the keyset. I've also never heard of the "ugh" editor. Most of Engelbart's contemporaries seem to have dismissed the keyset as unusable (despite a few enthusiasts who became highly proficient with it) Rbean 08:03, 26 March 2006 (UTC)

message: Wouldn't the Playstation controller and its friends fall under this category?  They're not designed for entering text, but they can be used that way, like for naming characters and saved games.  And, as a game controller, "chorded" combinations of buttons are standard.

Tiki® puts gold under your fingertips — a 6 keys mixed system for digital mobile convergence was linking to a site that contains absolutely no actual information about their keyboard - or anyone elses.  It doesn't add any content whatever to this page - it's a pure advert for that company.

message: User:Flewis has politely requested that I provide an informative edit summary for my edit.I have tagged several instances of usages such as "some question X" and "others maintain Y" with the  tag. This seems to me a very straightforward case of "weasel words", which we should be trying to avoid (generally by citing to a reliable source). We should eliminate these "some say", "others say" constructions by citing to specific sources saying specific things. -- 201.53.7.16 (talk) 15:38, 25 September 2008 (UTC)

message: Many discussions of keyboard accessibility mention chordal keyboards as an option. For some people who use one hand due to injury to the other, they may be the best option; conversely, for some people, one-handed or two-handed, who have coordination problems, it sounds like they may not be an option. Maybe it would be worth discussing who may find chordal keyboards more accessible or less accessible than conventional keyboards? 173.66.211.53 (talk) 00:56, 29 May 2013 (UTC)
