Text Based User Interfaces in the 21st Century? 120

Posted by Cliff
from the lose-the-rodent dept.
Jaap Geurts asks: "With the 3D GUI desktop around the corner, nobody seems to use or think about text based user interfaces (TUI) anymore. I know that hardware comes cheap nowadays but can the use of TUIs still be justified? I've always found that GUIs are resource hungry, generally slower and more importantly they often allow multitasking and they are very unpleasant without a mouse! What do you think about developing a (well designed) TUI for DB software (e.g Point of sale, Warehouse manager, etc)? Most current GUI metaphors can be implemented so what are the pros and cons from a user perspective?" Are there any real reasons against deploying text-based applications, today?

          A joystick is just as much a 2-dimensional pointing device as a mouse. In an airplane-like interface, the joystick controls the direction that the nose points, but you need the throttle to control forward motion.

          • Quite true... I stand corrected. I was thinking of how aircraft can move along x,y,z (yes, with throttle) and forgot that the stick itself only moves along x,y.
            • There are pressable and swivelable joysticks, though, either of which would give an additional degree of freedom.

    I've always found that in situations where I need to refer back to things that I've done (i.e. why exactly is my filesystem empty? Oh dear, a space in rm -rf asdf *) a serial, text based interface is the fastest way to work. You can quickly look back over operations you've performed in the recent past. The interface is consistant too, so any number of different operations look the same, no new interface to learn.

    GUI's on the other hand are good where you don't need that audit trail, or the information for the audit trail is unlikely to be used and can be condensed into a text-based format of some kind (think saving the undo-log in a wordprocessor to disk).

        Christ, man. You may be young, but surely you've run into more advanced TUIs than "enter everything as a command"?

        You'd have a screen with a field for profit and parts, and a menu for each of the choices. Look at menuconfig, one of the interfaces used to configure the Linux kernel for a build, for an example. CLI vs menu-based is different from CLI vs GUI. The problem of "displaying all the choices available so that the user doesn't need to remember the sequences necessary to invoke an action" is an issue between menu-based and non-menu-based UIs, not TUI/GUIs. It's even possible to have a GUI that isn't menu-based -- imagine a GUI that used, say, gestures for commands (as a few programs and games do today). Arx Fatalis, Black & White, Opera, etc.

        The main real benefits of a GUI over a TUI that I can think of are:

        * Use of images. TUIs generally need to fit on a standard console -- 24x80 -- and can generally rely on only ASCII characters, and perhaps bold and a few colors. A GUI can display full-color inline images.

        * Use of more input elements per screen. A GUI can make finer-grained use of the display for things like boxes and dividing lines to more clearly mark out where input is going. Since TUIs were designed in the days when displays were quite small, the 24x80 size is really ridiculous in this day of 19" CRTs, but most GUIs allow effective use of all the screen space.

        * More effective use of the mouse as an input device. The mouse is pretty good for doing things like selecting an arbitrary subset of items in a group (such as with a window full of selectable icons), or quickly inputting approximate values (such as with a slider). I think that the mouse tends to be overused in a lot of places, that for a lot of applications keyboard input to a TUI is faster and more accurate. The mouse is limited to being used in a very poor resolution, normally.

        * Familiarity to users of other GUIs. The windowed GUI is a common input paradigm to almost all computer users today. There are a number of complex operations (like addition and removal of an element to a discontiguous group of selected elements via control-clicking) that have already been taught users of Windows. Software using the Windows interface can expect users to know how to do these actions already, instead of having to instruct them in what to do. TUIs never enjoyed widespread conventions of the sort.

        * Windowed interfaces. The windowed interface paradigm is generally a very powerful interface mechanism, and one that can be taken advantage of in a GUI. If a computer is single-purpose and running only a single program, this may not be such a benefit, but on computers that may run many programs, having the ability for a user to do windowed work is a great benefit.

        * Non-ASCII charset support. While there is support for non-ASCII characters on text terminals (I suspect there is even UTF-8 and kanji support), most modern GUI environments provide good built-in support for rendering international characters -- TUI environments may not. This is not a hard constraints on TUIs, but given the existing TUI/GUI environments around, it is a practical advantage.
        • From your comments, I'm guessing you don't have a lot of experience with TUIs. I work for a company that does credit card processing on Tandem computers (that's a brand name, not just a funny name for an SMP system (although it's that too)), and we have text-based interfaces to *everything*. ...and here's why you're wrong:

          * "Must fit on a standard console (24x80)" and "Use of more input elements per screen". Any decent TUI will allow you create multi-page interfaces. Some of our TUI screens have 32 page
          • "Must fit on a standard console (24x80)" and "Use of more input elements per screen". Any decent TUI will allow you create multi-page interfaces.

            Right -- I may not have used correct terminology, but this is what I intended to say. I used "per screen" rather than "per page".

            "Familiarity to users". Not really a big deal. TUIs tend to be very simple, and a lot of things that work in [insert your favorite GUI] work in TUIs as well - tab to move between fields, there's a standardized help key, etc.

      Text-based != Command-based.

      There is such a thing as text based menus. POS systems in department stores are often text/menu based, although they are moving to GUI I've noticed. I see no benefit in having a GUI client for a POS system running on Windows(tm) when a 3270 session (or similar) would require cheaper hardware at the checkout and less futzing with the mouse (keyboard-entry / barcode-scanner-entry is quicker than point-n-click). It's not about looking pretty, but being able to process transactions quickly.
      I work in a call-centre where average handling time of calls is the most important metric (actually, customer satisfaction is more important IMNSHO, but that's harder to measure so they go for AHT instead). We use several different clients to various customer databases and billing systems, and the text-based (3270) clients are so much faster than the gui ones. The drive to swith to GUI for the sake of using GUI is one of my pet peeves.

        i started working at my local CompUSA as a sales drone (please no jokes - i've been done there for years) when it 1st opened, and we had dumb terminals for our POS and inventory. this meant that a sales person could generate a quote at any inventory station, hand the customer a piece of paper and they in turn hand the paper to the cashier who enters the number at the top and takes the money. the cool thing (in my inexperienced humble opinion at the time) as that as sales (and returns) went through, the inventory would be updated in real time.

        fast forward 3 months (yes, 3 months after the store opened!) and we moved over to a stupid frame-buffer based POS (it wasn't a GUI, you'll see why soon) that ran on some form of NT (i'm guessing NT4 because they looked like windows95 but these things had 24/7 uptime) now the cashiers had to know what key to press to do a specific thing (yes the dumb terminals had this too, but then they/we could tab from field to field) one operation at a time (it wasn't driven by the screen - as that was used to show the current recipt, and advertisements - but by the little green thing that shows the total!) with the new system, generated quotes were next to useless, (and soon we stopped generating them, and all but 1 printer used for those quotes disappeared from the sales floor) and, here is the best part: the inventory took up to 3 days to refresh! oh, we could still look up the all important % of service plans to everything else sold, but we couldn't rely on the computer to tell us what was in stock!

        soon lines grew, due mostly to the lost productivity of the cashiers, and they haven't shrunk since.

        today? the cashiers who knew the old system (yeah, there are one or two left) miss the good old says of the dumb terminals, and CompUSA still uses the POS that is a POS.

    Text is as much a component of graphical interfaces as widgets are. I would consider GUIs more of an expansion on text interfaces than a replacement for them. Consider that slashdot is 99% text based, yet your likely viewing it using a GUI. So your text interface hasn't gone away, it just got a great deal more flexible.

    And really, you can consider text-mode a graphical interface in the sense that the computer is displaying little graphics that we interpret. Advanced hieroglyphics. We recognize them as text, but others would see rows of silly icons.

    And this 3d desktop you speak of, will simply be an expansion of graphical interfaces, as I'm certain it will involve graphics. And I'm sure it will also involve text.

    There are of course other interfaces conceivable that wouldn't involve visuals at all. Such as text-to-speech and btty for the blind.

    I would imagine that the ultimate interface would be capable of interacting with humans using any and all methods. Of course I don't neccesarily want to taste anything my computer has to offer.

    Text interfacing will be around as long as we use text. As for text only interfaces, I'm a big fan of irssi and I'm not planning on giving it up any time soon.

  • When I started my current job, my boss gave me his box and built himself a much faster one :) I put up with the fans in his old box for only a day before I decided I had to do something. I moved the box into the server room and brought in my laptop to use as a terminal. No more fan noise!

    Pretty quickly I discovered that if I run all of my terminals in a screen session, I had much better control of them than if I ran separate xterms. You can only fit so many xterms on an X screen before you have to start using virtual screens, but you can easily fit dozens of terms into a screen session (I recompiled screen so I can have a hundred: I ran into the Debian version's maximum of 40 a few times). The best thing is, I can switch between them without using the goshdarned mouse. By giving them names, I can call them up with just a few keystrokes. Oh, it's nice. No more hunting. I want the screen I'm using to tail the apache log? It's ctrl-A ' log and I'm there.

    When I go home at the end of the day, I just disconnect my screen session. When I ssh in from home to do some work, or when I come in the next day, I just run "screen -r" and I'm back where I left off. Exactly where I left off. No time wasted starting up xterms and getting them moved around. The log term is still tailing the log, the edit term is still in emacs, the test term is still waiting for me to run the tests again.

    When I ssh into the noisy workstation, I use -X so I can run X applications if I want to... now and then the Gimp or feh or gv or some other GUIish thing, but running lots of terms in a screen session does lend itself to text mode applications. My email program is Pine, all text driven, and I like it just fine. Emacs in text mode, of course (no button bars for me!): Usually an emacs for each active project. When I switch from one task to another, I don't have to do anything but switch to the right screen session and start typing.

    Text-mode programs and screen are all I need to rule the world (or at least the part of it that sits on my workstation).

    I find it crazy that people put the blame on the technology (GUIs make slow software!) when the blame should be on bad developers. Just because a button is on a screen doesn't mean there shouldn't be a hotkey for it. Just because the GUI lets new or stupid users be productive doesn't mean that the software can't also let advanced users do things quickly. And a TUI (as opposed to a CLI) is exactly the same as a GUI, except with a different back-end for the rendering. I mean, come on, all the metaphors are the same. You can't tell me that text-based menus and input boxes are somehow superior to graphical ones from a usability perspective. One poster wrote about using Screen to allow disconnecting and reconnecting sessions, so that he doesn't need to close his work and can access it from anywhere. Well, that is useful, but it will eventually happen with GUIs (It's already partly there, with things like VNC).

    1. Scriptablity.

    You can write a shell script for most tasks that you already know how to do from the command line trivially. Others can be a bit tricky, but tools such as expect usually make it possible.

    Scripting a gui is usually only possible with special applications that scrape the screen and allow you to make macros. Some gui apps (notably KDE) have built-in scriptablity, but only to the extent that the developer goes out of his way to add it.

    2. Efficiency.

    For a good discussion see "The Pragmatic Programmer."

    While textual interfaces have an inherently steeper learning curve, they are far more efficient for the experienced user.

    This manifests in several ways. For example; all command line functionality is at the "top level" of the interface. One needn't click start before invoking grep, or click a pull-down to get to the case-insensitivity option.

    Think about it. We are visual creatures. we see things in terms of shapes and colors. Not words and lines. The first writings were cave drawings. Then we got up to hyroglyphs, then to sandscript and the like. We were born with the idea of an image. It took thousands of years to coalesce it into witten words.

    When we have a vocabulary. A set of established words. You do not need any vocabulary when it comes to images, though you do need to anticipate what images the user is familiar with. Like VCR controls.

    Text-UIs require language:words, grammar and syntax. GUIs don't. You cam make a multi-lingual application easily if you never need a word. Though, you may need to make a application multicultural by changin out the icons. Still you don't need a right-to-left reading order, verb tenses and plurality.

    Animation (eek) can help to avoid words, when statuc icons are not enough. but the way the mind works, the mind will learn the icon and the action quicker, so the icon need not always be animated- just animated during training. it is alto easier to share artwork between applications for a consistant experience.

    A lot of other posters have already explained reasons why they are, so instead of rehashing their arguments, I'll just give some real-world examples with which I was involved.

    My mother had two stores at one point, both of which used computerized point-of-sale systems. The system was DOS and worked pretty well. It did the reporting she needed, interfaced with mechanized cash drawers, a poll display, and a bar code scanner. Things worked pretty well, and it was even networked and had two machines. She was much happier than with the old system of a cash register with a lot of hand inventory keeping.

    Then, the vendor decided to come out with a new Windows based system. She was very reluctant to change because the new system meant having to buy all new hardware and some new training for her and her employees as many of the screens had changed. But, she couldn't continue to get support for the old DOS based system because the vendor, understandably, wanted to only support their new Windows-based system.

    So, the new system was installed. Aside from the enormous migration problems which aren't relevant here, she was really unhappy with it. Mice do NOT work well in a retail environment where they are used constantly and get gunk inside their roller balls and buttons. Employees tended to not learn shortcut keys because they seemed to perceive the mouse as easier to use, whereas in the old DOS system, they had no choice but to use keys. The keyboards were beasts and never seemed to die, but the mice did.

    There were no new features that interested her at all; she forked out the $10K+ to upgrade because she had to. During the holiday season, the cashiers were slower with the new system than with the old one, in general, partly because they didn't use shortcut keys and partly because shortcut keys weren't always usable in all screens and situations.

    Done properly, a GUI can be just as effective as a TUI, but all too many times, a lot of the GUIs I've seen for repetitive tasks (e.g., telemarketing data entry, POS, etc.) are horribly inaccessable. Since TUIs, at least to some degree, have to be accessable, they often work better.

Sure, if we threw a GUI on an older model computer, we'd be seeing a big difference in it's performance, but don't you think that TUI is just obsolete now? I respect everything that it has d
