User interface ideas

Anybody found a "nice" way to get users to create and use complex filters? I have simple filters and they work well: A drop down for Type: Name, and four different classes. If it's the name, then they get a drop down to select "Contains", "Starts with", "Ends with", "Does not contain" and so forth together with a text box. If it's one of three classes, you get a drop down for "Includes all of", "Includes any of", "Includes none of", and "Does not include", together with a dropdown list of valid values. The final class gets just "Is in" and "Is not in" and a dropdown list. All grouped up in a simple control that I feed a list, and it does the filtering. No problems. Now I've had a request for making it more complex:
"Name Contains 'ABCD' AND Class Includes any off <list> OR Otherclass Is not in <AnotherList>"
for example. Coding wise this is a doodle - that's partly why I made a filter control in the first place. It's trying to work out how to present it to an average user so it's easy to create, understand and edit that's giving me problems. I was thinking of a tree of some kind so it's obvious if the example above is
"A AND (B OR C)"
or
"(A AND B) OR C"
but I'm not sure a tree is that obvious to the average joe... Anyone seen a good way? And I'm not after code, just the presentation ideas - so this isn't a programming question! :laugh:

I once was told to design a boolean filter diagram for a similar kind of thing but to support potentially many, many conditions and groups of conditions. I ended up with a set of boxes that could be dragged around a panel and connected with ANDs and ORs and NOTs and then would be grouped (actually showing parentheses sort of in the background). It was fun to do at first but ended up being a nightmare when I had to add BETWEEN and some similar list based things. I would avoid the GUI approach unless you have six months to spare! I think most users will either understand the parenthetical approach - or will learn to if they have to use it repeatedly. Good luck

I've not seen one that does this but there are 2 things I would certainly do. Break down the expression building so that at any time the user is building a single operator condition A AND B and then B OR C. Allow them to use the conditions they've already created as the A or B in subsequent conditions. This does two things: It limits the otherwise unlimited potential UI complexity and it makes the user think in a way that means confusion of A AND (B OR C) with ( A AND B ) OR C is unlikely. At all stages as the expression is being built show the user the query text. The slightly intelligent ones will soon spot how it works. Allow them to bypass much of the UI by simply entering a query directly, not by overwriting the displayed partial one but in another parallel edit control. This is where validation becomes a major issue but it can be done. Only if the directly entered query passes validation should they be given the option to use it to replace the built query. When I went to university it was still assumed that GUIs could not be used to create SQL queries as SQL was too complex. We laughed at the lectures who sagely told us this. Now it's often assumed that users are incapable of learning to use a simple query language and will have heart failure if they are shown anything so code-like. They must use a GUI that hides all the details from them and teaches them nothing. Revolution, counter revolution but nothing actually gets improved, what are we French? :doh:

Are you "constrained" in any way here in terms of the UI you present: is the UI for this going to be visible, at all times; or, is it okay if a special UI "pops-up;" or, is it the case, perhaps, that for very simple (typical) use cases, there will be an always visible UI, with an option for the user to "pop=up" a more complex one in which arbitrarily complex logical expressions can be created ? And, how complex is the end-user allowed to make the query ? Is it the case that, as you describe in your current example, that two Lists<Stuff> are always going to exist, and that the user cannot modify these lists (create, or, edit) them ? This is a very interesting UI design challenge, I think, and I wish CP had a forum for UI/UX design issues. yours, Bill

Have a look at the DevExpress filter control[^]. You can make the filter as complex as you'd want to, while staying easy to use. Well, as easy as it gets when it can do "everything". It's not that quick to use though I have to say.

That's pretty close to what I was originally thinking with the "tree" idea. I understand it, I'm just not sure the indentation makes it that obvious to a "normal" user.

On the level of UI design, you, and I, are, evidently, somewhat compatible :) The challenge in your "parallel entry mode" model is, I think, validation of the user-entered query in standard boolean expressions (or whatever format) text. imho, unless you want to make a heroic effort, this is a slightly binary choice: if the user entered, in text-mode, a very complex nested filter, synchronizing the visual presentation of the GUI-mode filter facility with the text expression could be daunting. What if the user enters, in a TextBox: Contains "AB" && (! Contains "BC") || Contains "BC" || "CD" && (! BeginsWith("AB")) ... keep on going ... I'd solve this in a kind of "Alexander cuts Gordian Knot" style, by simply having the visual-mode facility "hidden" when the user decides to edit the contents in text-mode facility. As I said to OriginalGriff, I wish CP had a UI/UX forum for discussion of these kinds of ideas. yours, Bill

No real constraint - a pop up is probably the way I'll go, as the details of the filter would just clutter the display and serve no real purpose (I'll probably let them "name and save" them then display the name instead of the detail on screen) - that's part of the reason I want to get it as obvious as possible how to use it since I suspect they will actually use it maybe a couple of times a year after the initial enthusiasm has worn off. Complexity? Not sure. I suspect they won't make really complex ones - in reality they will probably be ok with "A AND B" or "A OR B", but once I've issued it it's a lot harder to change it to allow for "(A AND B) OR C" if one person needs it in six months time! :laugh:

I agree. If the user is going to enter the query in textual expression form they probably don't need it represented in another form by the GUI. The graphical builder can close/grey out at that point. The good thing about the dual approach is discoverability. The user can begin constructing a query with the slow but simple GUI, see how the textual Boolean expression works with &&, ||, ! and the various functions and then cut to exactly what they want by typing it in. Most users will initially ignore the code string being built up for them but will absorb subconsciously and quite effortlessly what &&, || and ! mean. When they later see a Boolean expression they'll understand what it means and they probably won't even know how. It will just be obvious. :)

Quite some, but "nice" is a very stretchable term. It's always a tradeoff between power and simplicity. The DevExpress filter is a "nice" one, in that sense; one can define a simple filter in the grid itself[^], or a complexer filter using an editor[^]. The complexer filter is all that the average user doesn't want; a column to denote "and/or", a column for the field-name to operate on, a column for the operator and a column for the value. Most home-made filters will act like the DevExpress-version; a grid that holds the same info. It's not recommended for novice users. It seems as if you do not only have filters, but also multiple datasources/tables to choose from. I've lost the bookmark, but there's a freeware QBE-editor available for .NET (similar to Active Query Builder[^]); works exactly like the Query-editor from Microsoft Access. I'd recommend that one as it's very easy to operate - simply hand them a manual for MS Access. If your audience isn't built from novices, I'd suggest putting a textbox in there and have the user type his/her filter. It's very effective, powerfull and easy - my favourite.

So, how does your average Joe muck around in his/her UI? I'm all in favor of keeping the Win3.11 UI, as it's familiar to most users - things always work in the same way. Then, when I look at the average Joe and his phone, I often wonder how they ever discovered that there's a function hidden in a particular screen.

I guess it all boils down to is what mentality of audience are you writing for? I once developed a test machine (shake and bake) for a US plant in Mexico and they told me to make the results of the test as simple as I could. I output everything to a mechanical meter and told the foreman that if the results where within a certain range it was acceptable anything outside the range wasn't, he asked to borrow a sharpie that I had in my pocket and drew lines on the meter and said if I hadn't done that they would not have been able to figure it out.

I know what you mean: I used to design industrial printers for products on conveyors. One of them went in a cement factory, and one guy had the job of making sure the printer was working fine, then standing at the end of the conveyor catching cement bags and stacking them on a pallet for eight hours a day...

If it's one of three classes, you get a drop down for "Includes all of", "Includes any of", "Includes none of", and "Does not include", together with a dropdown list of valid values. The final class gets just "Is in" and "Is not in" and a dropdown list. All grouped up in a simple control that I feed a list, and it does the filtering. No problems. Now I've had a request for making it more complex:
"Name Contains 'ABCD' AND Class Includes any off <list> OR Otherclass Is not in <AnotherList>"
for example. Coding wise this is a doodle - that's partly why I made a filter control in the first place. It's trying to work out how to present it to an average user so it's easy to create, understand and edit that's giving me problems. I was thinking of a tree of some kind so it's obvious if the example above is
"A AND (B OR C)"
or
"(A AND B) OR C"
but I'm not sure a tree is that obvious to the average joe... Anyone seen a good way? And I'm not after code, just the presentation ideas - so this isn't a programming question! :laugh:

I have designed a simple filter control for LIKE as well as AND/OR logic. For anything more complex I have an export to Excel button with which the users can export the data and use the Excel filters - my view is that if the user wants sophisticated filtering then outside of using SQL, Excel is probably the next best thing.
