I am writing a Mac application that provides a "test" like function. This application (through a connection with a server). Basically the application will give the students a story to read, followed by a series of questions (also from the server) where the user can (attempt) to select the correct answers, and send the result back to the server to be verified.
Implementing the "story" part was easy. Just send all of the text to a NSTextView. I had been planning to implement the "select your answer" as programmatically created NSSwitchButtons. However, some of the possible answers might take up more than one line. I have not been able get (any) NSButton class to wrap text based on the frame size, and there doesn't seem to be an easy way to override NSButtonCell to allow the text to wrap.
What other Cocoa class(es) should I use to accomplish this task? I need to have a check-box interface (so that people can select one or more possible answers, and the answers can be an arbitrary length - within reason!) Ideally it would also be easy to use so that it will be easy to programatically layout the answers as well. (Some problems may only have 2 choices, while others may have 5+) I can't imagine I'm the only one who needs this type of functionality
(Oh...since a picture is worth 1,000 words, I've attached a screen-shot of my app below with some answer text running off of the screen)
An NSButton will respect explicit linefeed characters embedded in the text, but I suppose that would not meet your needs. An alternative would be to have a static text item next to a checkbox with no title. Of course, if you want to be able to toggle the checkbox by clicking the text, you would have a little more programming to do.
I have little experience in developing GUI for desktop applications, but I want to develop a typical GUI for creating/editing entities (e.g. Customer, Suppliers, etc.) which would be similar for many cases and would be comfortable for the users.
[* Please don't close the question. I put much effort in preparing the question and I really need help. *]
After analyzing our tasks I designed the following possible options:
1) In simple cases it is possible to solve the task by using an ordinary grid:
I.e. the workflow is: On pressing the Add button, a new row is added to the grid. On pressing Delete the user is asked for confirmation if he/she really wants to delete the focused entity instance. On pressing Save all previously made changes are saved. On pressing Close the form is closed (user is asked if he/she wants to save changes before closing).
Cons: I think such a GUI will only work for very simple cases. Editing something complex in a grid is not comfortable neither for a user nor for a developer (implementing complex editing in a grid will not be trivial I think).
2) For more complex entities the following option is possible:
The grid is used here only in the read only mode. On pressing Add a modal form for filling information about a new entity is shown. On pressing OK in that form the data is validated and if everything is ok the object is added to the grid datasource. On double clicking on a grid row the same form for editing the chosen entity instance is shown.
Cons: For every entity we will have to create 2 forms.
3) Another possible option:
The grid is also in the read only mode. When focusing a row in the grid, the fields above the grid are filled and a user can edit them. On pressing Add a new entity instance (object) is created and added to the grid's datasource, then the new row is focused, fields above the grid are cleared (binding helps here), the cursor is placed to the first field and the user can start typing.
I don't see any cons here except that maybe you will not have enough place for the grid and the fields on the same form. I like this option though I don't remember that I saw it anywhere.
I tried to ask the users of my program to help me decide which GUI is better for them, but the typical answers are "I think both options are ok" or "I don't know, you decide which one is better".
Now I would like to ask people with experience in GUI design the following questions:
1) Which option do you use usually? Maybe another one (not shown above)?
2) Would be nice if you also said a couple of words about your implementation (dataset/custom business objects/binding, etc.)
3) Which cons did you notice in my options?
4) Any advice on what I can read on the subject?
Thank you for help!
Junior1993, This is a great question, and there are many online resources that will spell out the trade-offs of each of these interaction design patterns, when to use them, and when they are most effective. You did not provide project-specific details, so it's impossible to answer those questions.
The "Work With" pattern is the foundation of your write-up, and you were asking about the pros and cons of different variations. Here is some reading on "Work With": http://quince.infragistics.com/html/PatternView.aspx?name=Work+With
All of the patterns you described are well-documented and can be modified to fit different purposes.
Your #2 pattern is "Edit-In-Place". It can also be found on the Quince site.
Your #3 pattern is "Two-panel selector".
This one takes many forms, but it helps to preserve context while editing.
The one you did not mention was "New-Item Row". You might want to look at that one, too, and select the pattern or combination of patterns that best fits your users' goals and the content they are creating/editing.
There are other pattern websites out there, and most build on the work of Jennifer Tidwell, author of "Designing Interfaces", an interaction design classic.
Best of luck to you!
I'm currently working on a program that has many of those "the user SHOULD read it but he'll click OK like a stupid monkey" dialogs... So I was thinking of adding something like a captcha in order to avoid click-without thinking...
My ideas were:
Randomly change buttons
Randomly position buttons somewhere on the form
The user must click on a randomly colored word within the text he should read
add captcha
add captcha that includes the message for the user
Has anybody made any experience with such a situation. What would you suggest to do?
Well, you asked for opinions and here goes mine, but I don't think this is what you would like to hear...
Users like programs that they can depend on. They don't like when things change and they don't like to do extra work.
Randomly change buttons and Randomly position buttons somewhere on the form will only make them either press the wrong button or become annoyed with your application, because as you say, they don't read the text, and if you think about it, neither do we. As an example think of an Ok/Cancel dialog, you allways expect the ok button to be on the left, and most times i press it without reading it. It Will happen exactly the same with your users.
The user must click on a randomly colored word within the text he should read
add captcha
add captcha that includes the message for the user
With these 3 option you will add extra work to your application, your users will curse you for that. Just think of something that you would have to do 10x per day, let's say check in your code to source safe. How would you feel if your boss told you that from now on you will have to fill a captcha for each file you try to check in?
I think it's our jobs to make the lives of the people that use our software easier. If they must read some kind of text and they don't want to, there is absolutely no way you can make them do it.
You can´t make people work right, all you can do is provide them with the best possible tools and hope that they are professional enough to do their jobs.
So basically all i'm saying is, do your best to ease their work. If this is really important than you(or whoever is in charge) should talk to them and EXPLAIN WHY this is important.
You would be surprised on how people commit to things they understand.
I suggest that you don't; and that, unless you know better, you emulate respectable well-known, well-tested UIs like <big online retailer's> or <online banking site>.
Playing games with the user in order to get them to read messages is doomed. Users will focus mental resources on completing your game, rather than understanding the message. Your users may be less likely to actually understand the important part of the message if you have things like moved buttons, relabeling, scavenger hunts, captchas, or delays. They’ll focus on the instructions for the game, not on the real issue. Errors are likely to increase.
Users’ refusal to read message boxes is due to users wanting to get things done quickly rather than take the time to read stuff, and it is also due to message boxes being overused and misused so badly in so many apps. Including silly games in message boxes will just make users resent them all the more, compounding the problem.
Here’s what you can do:
Rule 1. Don’t use messages boxes. They should only appear for exceptional circumstances. An app should not have “many” message boxes. It should not be necessary to read a whole lot of documentation each time the user uses an app. If normal use of your app results in a message box, then your UI is wrong. Find another way.
Instead of verification messages, show clearly in the main window what has happened and provide a clear way to Undo it.
Use auto-correction, pictured/masked fields, and disabling rather than error messages.
Use good defaults and automation to avoid messages. For example, rather than showing an error message saying the user can’t upload because they’re not connected to the server, simply reconnect automatically.
Break commands along options. Rather that a message box to ask if the user wants paste with or without format, provide two different commands in the menu.
Don’t have information messages spontaneously popping up telling the user everything worked fine (e.g., “Preferences Saved!”)
Don’t have pop-ups providing helpful hints or documentation. Provide a tutorial or balloon help if you can’t make your UI self-documenting.
Don’t have nagging “upgrade me” messages.
Consider providing message text in the main window rather than in a separate message box (e.g., “Page may not look or act right because ActiveX is off for security.”). Pop-ups from web surfing have conditioned users to automatically dismiss anything that pops up as irrelevant.
Rule 2. If you have to use a message:
Make the text as brief as possible to get the key information across. More text is not equivalent to more helpful. Use “No match to [filemask] in [path].” Don’t use “Nonfatal Error 307: Search action aborted. [Appname] is unable to complete your string search for the regular expression you provided because the file mask you gave, namely [filemask], does not result in any matching files in the directory that you specified (which was [path]). Please check your filemask or path selection and again re-enter it or them in the Files to Search dialog box. Click the OK button below on this message box to return to the Files to Search dialog box. Click the Cancel Button on the Files to Search dialog when you get there to cancel your search for strings.” If there are some users who will need more explanation than can be achieved in a brief message, provide a Help button or a “How do I…” link in the message box.
Use plain language and no jargon in the message. That includes “innocent” words like “dialog,” “database,” and “toner.” Do not take raw exception text and throw it in a error message. Do not include any error numbers or dumps; log these instead. Purge your app of any debugging message boxes left by developers. Better to simply let the app disappear on a fatal error than to put up a message full of jargon and then the app disappears.
Label the buttons of a message box with what the action does, not “OK.” At the very least, the users have to focus on the activating button to dismiss a message box. If that button is labeled something like “Delete” or “Install,” it should give them pause. You should never have to explain in your message text what each button does. BTW, such labeling is a GUI standard on most platforms.
Redesign your application so that it does not use message boxes.
My suggestion, live with it or redesign your dialogs/interface. Do not add randomness to dialogs or otherwise treat the user like an idiot, even though you may think most are :-).
I just recently read a Joel on Software article, Designing for People Who Have Better Things To Do With Their Lives. It makes the point that most people won't read anything and discusses ways to work around that or at least not make it worse.
You could try with a timer which waits for the "supposed reading time" before enabling the submit button. You can even calculate the supposed reading time from the number of words.
I think that subtle ways to force the user to read your text (like moving around buttons or asking them to read a captcha) can make them feel like stupid monkeys.
You could use a choice question based on what the user should read.
As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion.

What techniques do you know\use to create user-friendly GUI ?
I can name following techniques that I find especially useful:
Non-blocking notifications (floating dialogs like in Firefox3 or Vista's pop-up messages in tray area)
Absence of "Save" button
MS OneNote as an example.
IM clients can save conversation history automatically
Integrated search
Search not only through help files but rather make UI elements searchable.
Vista made a good step toward such GUI.
Scout addin Microsoft Office was a really great idea.
Context oriented UI (Ribbon bar in MS Office 2007)
Do you implement something like listed techniques in your software?
Edit:
As Ryan P mentioned, one of the best way to create usable app is to put yourself in user's place. I totally agree with it, but what I want to see in this topic is specific techniques (like those I mentioned above) rather than general recommendations.
If you do give the user a question, don't make it a yes/no question. Take the time to make a new form and put the verbs as choices like in mac.
For example:
Would you like to save?
Yes No
Should Be:
Would you like to save?
Save Don't Save
There is a more detailed explanation here.
Check out the great book Don't make me think by Steve Krug.
It's web focused but many of the conepts can apply to anything from blenders to car dashboards.
Topics covered:
User patterns
Designing for scanning
Wise use of copy
Navigation design
Home page layout
Usability testing
He also has a blog called Advanced Common Sense

To add to your list, aku, I would put explorability as one of my highest priorities. Basically, I want the user to feel safe trying out the features. They should never back away from using something for fear that their action might be irreversible. Most commonly, this is implemented using undo/redo commands, but other options are no doubt available e.g. automatic backups.
Also, for applications that are more process-oriented (rather than data-entry applications), I would consider implementing an interface that guide the user a bit more. Microsoft's Inductive User Interface guidelines can help here, although you need to be very careful not to overdo it, as you can easily slow the user down too much.
Finally, as with anything that includes text, make the user interface as scannable as possible. For example, if you have headings under which commands/options appear, consider putting the action word at the start, rather than a question word. The point that Maudite makes is a good example of scannability too, as the "Don't Save" button text doesn't rely on the context of the preceding paragraph.
A useful technique which I never see anyone use is to add a tooltip for a disabled UI control explaining why the control is disabled. So if there's a listbox which is disabled and it's not clear why it is disabled, I want to hover over it and it tells me why it's disabled. I want to see something like "It's disabled because two textboxes on the screen were left blank or because I didn't enter enough characters in some field or because I didn't make a certain action.".
I get into sooooo many such situations and it's frustrating. Sometimes I end up posting in the software's forum asking why a control is greyed out when a tooltip could have helped me in a second! Most of these software have help files which are useless in these kinds of scenarios.
Try to pretend you know nothing about your software and try using it. However this is not practical because you already have a certain mind set towards the app. So watch fellow developers or friends use the app and look out for the pain points and ask for feedback.
One of the classic books to help you think about design is "The Design of Everyday Things" by Donald Norman. He gives great real-world examples. For example, if you design a door well, you should never have to add labels that say "push" and "pull." If you want them to pull, put a handle; if you want them to push, put a flat plate. There's no way to do it wrong, and they don't even have to think about it.
This is a good goal: make things obvious. So obvious that it never occurs to the user to do the wrong thing. If there are four knobs on a stove, each one next to an eye, it's obvious that each knob controls the eye it's next to. If the knobs are in a straight line, all on the left side, you have to label them and the user has to stop and think. Bad design. Don't make them think.
Another principle: if the user does make a mistake, it should be very easy to undo. Google's image software, Picasa, is a good example. You can crop, recolor, and touch up your photos all you like, and if you ever change your mind - even a month later - you can undo your changes. Even if you explicitly save your changes, Picasa makes a backup. This frees up the user to play and explore, because you're not going to hurt anything.
I've found UI Patterns to be a useful reference for this sort of thing. It's arranged much like the classic GoF Design Patterns book, with each pattern description containing:
The problem the pattern solves
An example of the pattern in action
Sample use cases for the pattern
The solution to implement the pattern
Rationale for the solution
If you implement a search, make it a live search like what Locate32 and Google Suggest does now. I am so used to not pressing "Enter" at the search box now.
Well, one thing that may be obvious: don't change (even slightly) the position, color, font size, etc. of buttons, menus, links, etc. between screens if they do the same type of action.
Really good feedback is extremely important. Even simple things like making it obvious what can and cannot be clicked can be overlooked or too subtle. Feedback when something might happen in the background is great. In gmail, it's great that there's a status ribbon appearing at the top that let's you know if something is sending or loading, but it's even better that it lets you know that something has sent successfully or is still loading.
The "yellow fade" technique is something else made popular amongst the RoR crowd that accomplishes something similar. You never want the user to ask the question, "What just happened?" or "What will happen when I do this?".
Another trick that has become more popular lately that I've been using a lot is editing in place. Instead of having a view of some data with a separate "edit" screen (or skipping the view and only having an edit screen), it can often be more user friendly to have a nicely laid out view of some data and just click to edit parts of it. This technique is really only appropriate when reading the data happens more often than editing, and is not appropriate for serious data-entry.
If you are doing enterprise software, a lot of users will have small monitors at low resolution. Or if they are old they will have it at a low res so they can see giant buttons ( I have seen an 800x600 on a 24"ish monitor). I have an old 15" monitor at a low resolution (800 x 600) so i can see what the program will look likes in less than idle conditions every now and then. I know that enterprise users pretty much have to accept what they are given but if you design a winform that doesn't fit into an 800x600 screen, it's not helping anyone.
Try to think about your user's end goals first before deciding what individual tasks they would carry out when using your software. The book About Face has excellent discussions on this sort of thing and though quite long is very interesting and insightful. It's interesting to note how many of their suggestions about improving software design seem to used in google docs...
One other thing, keep your user interface as simple and clean as possible.
Here is a great DotNetRocks podcast episode where Mark Miller talks about how to create Good UI; Even though the show title is .NET rocks, this episode talks about a general rule of thumbs on how to create a UI to increase program user's productivity.
Here is an episode exerpt
Good user interface design can be done by sticking to some good rules and avoiding common mistakes. You don't need to be a latte-sippin tattoo-wearin macbook-carrying designer to create user interfaces that work.
I like to follow these 3 guidelines:
Standard - follow known standards/patterns, reuse ideas from all products you respect
Simple - keep your solutions simple and easy to change (if needed)
Elegant - use less to accomplish more
The best technique I found is to put your self in the users shoes. What would you like to see from the GUI and put that in front. This also gives you the ability to prioritize as those things should be done first then work from there.
To do this I try to find "layers of usefulness" and add / subtract from the layers until it seems clean. Basically to find the layers I make a list of all the functions the GUI needs to have, all the functions it should have, and all the functions it would be neat to have. Then I group those so that every thing has logical ordering and the groupings become the "layers". From the layers I then add the most important functionality (or what would be used for Day to Day operation) and that becomes the most prominent part, and I work things into the feature around those items.
One of the toughest things is navigation as you have so much to give the use how do you make it helpful and this is where the layers really help. It makes it easy to see how to layout menus, how other pieces interact, what pieces can be hidden, etc.
I have found the easiest way to do this is to start by see what and how your users function on a day to day basis this which will make it easier to get in their shoes (even better is to do their job for a few days). Then make some demonstrations and put them in front of users even if they are Paper Prototypes (there is a book on this process called Paper Prototyping by Carolyn Snyder). Then begin building it and put it in front of users as it is built often.
I will also recommended the book Designing Interfaces by Jenifer Tidwell published by O'Reilly
The items in the list you presented are really situation dependent - they will vary from application to application. Some applications will need a save button, some won't. Some conditions will warrant a modal dialog box, some won't.
My top rule for designing a usable interface: Follow existing UI conventions. Nothing confuses a user more than a UI that doesn't work like anything they've ever used. Lotus Notes has one of the worst user interfaces ever created, and it is almost entirely because they went against common UI conventions with just about everything that they did.
If you're questioning how you should design a certain piece of your UI, think of a few standard/well-known applications that provide similar functionality and see how they do it.
If your UI involves data entry or manipulation (typical of business apps) then I recommend affording your users the ability to act on sets of data items as much as possible. Also try to design in such a way that experienced users can interact with the UI in a very random, as opposed to sequential way (accelerator keys, hyperlinks, etc).
Sung Meister mentioned Mark Miller. You can find some of his blog posts regarding great UI on the Developer express blog. Here's a screencast of his Science of great UI presentation: part1 and part2. (both require Veoh player).
You can also find him on dnrTV: Science of great user experience: part1 and part2.
Here's a google techtalks about user experience by Jen Fitzpatrick.

When using a dropdown, the default dropdown height is usually too low (default is 8 items for winforms, for example).
Increasing it will either save the user a click if the number of items is low or make it easier to search the dropdown if there are a lot of items.
In fact, I see little point in not using all the available space !
This is so obvious to me now, but for example, it seems even VisualStudio designers haven't figured it out (btw, if you manually increase Intellisense's height, it will stay this way, but that's offtopic:))
I'll give one of my personal favorites: avoid dialog boxes at all costs. A truly good U I should almost never need to pop up a dialog box. Add them to your program only as a truly last resort.
For more, you might want to check out easily digestible ui tips for developers.
The Coding Horror Blog regularly gives great ideas. Just some examples:
Exploratory and incremental learning
Self-documenting user interface
Incremental search of features/Smart keyboard access
Task-oriented design (ribbon instead of menus and toolbars)
Providing undo instead of constant confirmation
Another aspect: use scalable icons to solve the problem of multiple user screen resolutions without maintaining different resolution bitmaps.
