These names are more indicative of the field. "chi" is the name of the conference (computer-human interaction) and "hci" is the commonly used name in the literature for the field (human-computer interaction). This does not preclude human factors materials and may in fact focus these materials to those that apply to computers.

Now I'm almost at the point of unsubscribing because the discussions seem so remote from this very basic issue. As an application developer for users who must be assumed non-computer-literate (whatever that means in 1987!), discussions on this level would be much more helpful.

I believe comp.chi or comp.hci is unnecessarily narrow, as indeed is 'cognitive' engineering. Human factors engineering addresses interesting issues at the physiological, perceptual, and social -- as well as the cognitive -- levels. Also, we are concerned with human interaction with complex engineered systems other than computers -- e.g., life-support systems.

As someone very interested in user interfaces, and up to here with some of that ai stuff (sorry Steve), I agree too, but there's no need to risk articles on aircraft control placement - what's wrong with comp.hci (human-computer interaction) or comp.mmi (man-machine interface).

References: Sounds like a typical problem in human factors/ergonomics/ human-computer interaction: selecting a name. Now, it is well known that one should not select design parameters simply by thinking about it. One must either use previously accepted standards or do some experiments. Moreover, Landauer, et al have shown ad nauseum that there will NOT be any single name that will satisfy everyone nor meet all criteria. It is also well established that abbreviations cause difficulty. You, dear reader, may know what mmi or hci or chi or cogeng stands for, but you are not the problem. The problem is all the thousands of readers on the net who do NOT know those terms, but who can read into the abbreviated terms definitions consitent with their own needs. I therefore recommend a FULL name, at least as full as possible given the constraints of netnews. Two observations: 1. please do not revert to sexist terms. Some of us have gone to great lengths to eliminate such names as "man-machine interface" (MMI) from our vocabularies. Please do not restart its use. 2. CogEng or Cognitive Engineering. In this case, I suspect the misue of the term was not by misunderstanding. If I recall correctly, person X (no names) starting posting his articles here, even though I bet he fully understood the meaning of the term. Rather, he probably believed that the kind of psychologist/ cognitive scientist who might read CogEng would also be the kind of person who would be interested in that particular discussion. If I am correct about this, there is litle that can be done except to have someone try to stop it as soon as it starts. Perhaps I should have done so. The point being that those of us who were interested in that topic also got it in the AI list. 3. It would be a shame to lose the nice term CogEngineering, but I would be happy with any term that fit the requirements. Especially given my earlier comment that it is well known that no single name will meet all the requirements. Here are three suggestions: Ergonomics HumanFactors HumanComputerInteraction Take your pick. Personally I would prefer the current term, but spelled out more fully. CognitiveEngineering Donald A.

The standards may be de-facto ones: most people in the field refer to themselves as "user interface developers"; almost none call themselves "cognitive engineers". Another valid technique for correcting a defective design is to diagnose the bugs, and fix them. Cognitive engineering is strongly related to both ergonomics in general, and to psychology. People working in those fields post in comp.cog-eng because it is the "closest thing" to what they need but don't have, namely separate groups for those disciplines. I think that comp.cog-eng needs to be split into three related but separate groups: comp.user-interface sci.ergonomics sci.psychology I have added news.groups to the heading. Adam Reed (hou2d!avr)
craig@unicus.UUCP (Craig D. Hubley) (07/26/87)
Sort of long... bear with me. The problem, I think, with the name comp.cog-eng is that it could just as easily be understood as "the engineering OF cognition", although it was intended to mean "engineering FOR cognition". Thus Mr.Harnad's cross-posted "sludge". That former definition could be yet another synonym for AI. I don't think it is a good idea to splinter the human factors discussion across several groups. It is, after all, a holistic subject and that should be encouraged. This, to me, means keeping varied aspects of the discussion under a net-name. The creation of a group such as "sci.psychology" might prove useful, but in the absence of traffic it shouldn't be assumed. It would also serve to generate traffic on Freud and Jung - fine, but I've seen no one on cog-eng discuss matters that ought to be moved to such a group. If someone wants to discuss psychology relevant to human factors issues, of which there is a great deal, by all means do it in the human factors group. If there is a token psychologist posting to "comp.user-interface" and a token designer posting to "sci.psychology", that only makes the situation worse. Splintering and overspecialization was one of the things that has made human factors engineering such a poor cousin to other forms of engineering, when it should have been at the top of the heap. My solution ? (Of course, those who post criticisms must post alternatives! :-)). We have the "comp." prefix, why not simply add "for_humans", or some such, so that the purpose is absolutely clear. It may not read like other net names, but then this shouldn't be like other net groups. It isn't just USING the media of the computer, it's ABOUT the media and its effects. Sort of a meta-group. I don't think it's possible to misread: comp.for_humans comp.for.humans ? Wouldn't this solve the problem? And isn't this what it's about. I've had my say. My next post (to whatever is decided) will be about a real human factors issue. Maybe those participating in this current debate ought to do the same. Nothing gets a group back on track like content.

I like *all* the names suggested ... even the current one (which is undoubtedly well accepted by those who already associate "comp.cog-eng" with a "human-factors/man-machine interface/computer-human interface/ human performance engineering/human-machine interface/ergonomics" newsgroup).

When I first stumbled onto comp.cog-eng it was after searching for something with 'hum' or 'fac' in its name. Maybe there could be a limited number of variant forms, contained in a thesaurus, any one of which might lead an unsuspecting 'novice' to the actual name... after all, the 'expert' already knows. It could say, "known as comp.cog-eng" and PUT you there. Maybe it could also say, "See also: comp.foo and comp.foo1" e.g. g comp.hum-fac ... known as comp.cog-eng... There are xyz unread messages in comp.cog-eng... etc. etc. That's it! We've now invented, (wait for it...), THE CATALOG (...known as catalogue), at your local public library! This issue being resolved, we could then discuss who got to update the thesaurus! (Half of knowledge is knowing where to find it). The above is only a semi-flippant entry. It has always bothered me when I've dialed a whole load of numbers... e.g. (617) 555-1212 and gotten a recording telling me that I have to put in a "1" before the area code. If the durn machine is smart enough to tell me my mistake, why dosen't it just stick the silly '1' in there for me? It could always, for the sake of overkill, say, "I presume you meant 1-617... and unless you press '#', within 10 sec, I will put the '1' in for you...(thank you for calling AT&T)." Instead, I get the pleasure of looking up the number again and re-keying it. Of course, one solution would be an editable last-dialed buffer in the phone, but why bother the user *at all* if their mistake wasn't fatal? Down with controlled vocabularies! (apologies to any Aussies, make that 'up').

As a new site on the net I was quite excited about cog-eng; however, it seemed overpowered by comp.ai and I was about to unsubscribe. So much for that now. Regarding the group name. When we installed news a list was passed around with all the group names, with a short summary of what was what. Granted that may not be enough; but we assume that either a question will be asked, or the group will be read to determine the content. A rose by any other name ... :-> Sure its nice to get new readers in a group and I am sure that regardless of the name new readers will come and old will go. Leave it as it is.

In corresponding with Craig Hubley (Craig@Hubley.COM) we have agreed that self-referential newsgroups that exist only for the purpose of debating what they should be named are just plain silly. AND, further, Craig offered to get ball rolling and asked me what I would like to see discussed here. SOOoo, being more of a parallel type than a HumIntFacePerson, I have a parallel processing challenge for ye of net.land: Design the ultimate parallel debugging environment for a massively parallel machine. Assume a Unix-based environment and conventional procedural languages (C, fr'instance), and computing resources available to the debugger comparable to those available to the application being debugged (i.e., the debugger shouldn't try to allocate more than two or three more processing elements beyond those used by the application -- it is unacceptable to use 2N PE's to debug something that runs on N PE's). Assume any graphics/mouse/pointing device/disk space/OS support/network resources you find convenient. I claim this is a good topic to pull comp.cog-whatever out of its slump because it deals with the crux of designing a good human interface -- organizing huge gobs of data and presenting it to a person on demand in a form that will aid him in solving a difficult problem (getting a parallel program to run). Object-oriented programming is not to be considered (otherwise the topic would be too broad). Smalltalk already seems to have a pretty good debugger, though I am hardly intimately familiar with it. Feel free to borrow ideas from it if you think they're good ones that fit well. Theoretically, anything that's a good debugger for procedure oriented Lisp or C should be an all right debugger for object oriented Lisp or C, so upward expansion shouldn't be too awful. I'd settle for a good base, initially. Let me fill you in with a little background information. Here at the Ultralabs we have five 8-processor machines (the PE's are 68010's) that are prototypes for an N-processor Ultra, where N is around 4096 or so. Within several months a 64-processor machine using 68030's and much faster FP coprocessors should be built. All processors share a large, flat global address space (~1Meg/PE) and have individual private caches (~32K/PE), so that global memory is used primarily for communicating among PE's and for reading program instructions. The cache is big enough for loops to frequently run entirely within the cache. Coordination is done through the atomic operation Fetch&Add. Three control lines connect the processors to the memory elements: READ, WRITE, and F&A. The really neat thing about the Ultra is that it scales up very nicely because it has _no_ serial bottlenecks -- no critical sections in the OS (symunix, for symmetric Unix, as opposed to master/slave) and no waiting on global memory requests (all processors can read or write or F&A any location, even multiple PE's to the same location, in _one_ memory cycle). The debugger, on the other hand, is not nearly so sophisticated. It is called pdb (parallel debugger) and is based on sdb. With all due respect to its author, pdb has an ugly user interface, largely because I consider sdb's interface to be ugly. In contrast, the VAX/VMS debugger in full-screen mode I would consider to have a reasonably good user interface (it would be better if setting watch points on variables worked better so you could get the values of changed variables printed out intermixed with trace output). Imagine sdb with some extra facilites to handle parallelism (command enhancements and some extra commands) thrown in, and you'll have a good picture of pdb. Basically, any information you want you have to ask for, and the terminal is modelled as a glass tty (no windowing). The _good_ thing about pdb is that processes are arranged in groups and are stopped _as_ _a_ _group_ when a breakpoint or keyboard interrupt is encountered, so while you're examining variables and so on all the processes cooperating with the one you breakpointed are also suspended, giving you a static rather than constantly changing environment in which to poke around to see what's going on. My idea of the ultimate parallel debugger would be closer to dbx or the VMS debugger and would give each process it's own window. The idea of process groups would be retained, possibly qualified by a process' state, as in "I want these processes to stop when this one hits a breakpoint, but only if they have acquired A-locks. If they have acquired B-locks, they should continue on because I'm going to me modifying the variable they keep looking at in a loop and see what happens." It would also probably need to be able to halt all PE's, examine their state, then let all PE's [simultaneously] execute one instruction, examine state and print out any variables that changed, and continue to loop. Higher levels of granularity would require the programmer to pick a spot (or spots) in the body of a loop where the breakpoint should happen so selected variables or all changed variables can be printed out. As the code was executing I would be able to see where each process was because each would display a window full of code with the instruction at the current PC high-lighted at the middle, and a log of selected variable changes scrolling in a few lines at the bottom together with windows on selected variables. Unfortunately, the relative timing of concurrent processes is crucially important in uncovering bugs, and it would almost certainly be messed up beyond all recognition by the time taken to print all this stuff out. Hmmm. Perhaps an initial run could be done with a fixed overhead routine recording the time and current PC after each instruction, keeping a voluminous log, and then for the display run each process would be kept in synch with that log so as to maintain the original pattern of where PC's are relative to everyone else. Sounds like this ultimate debugger is going to run slower than snail speed or will require a hardware debugger... But that's OK, as long as the debugger can be designed into it. As a matter of fact, we're designing a board right now that snoops on the Ultrabus and records the last million or so addresses seen on it. Anyway, what do all you human-interface people / cognitive-engineers think about this? --John Hanley, / / ____ __ __ System Programmer, Manhattan College [ ..cmcl2!mc3b2!jh ] /__/ /__ / /-< /-/ Researcher, NYU Ultracomputer Labs [ Hanley@NYU.arpa ] "The Ultracomputer: to boldly go in log N time where no N processors have gone before."
