Imagine you are faced with a tablet-sized screen that is almost-but-not-quite a tablet.

  1. It has a physical keyboard, and there is no on-screen keyboard.
  2. It has a touch screen, but also has a port where you can attach a mouse if you want to use one.
  3. It has a stylus, but it's not obviously marked and therefore isn't much used.

The layout is simple, very much like an app found on a tablet. The menu is 1/4 of the screen width and aligned left. By selecting a menu item, that section is displayed in the remaining 3/4 screen width.

Very few of the sections have an additional level into which you can 'drill down', but for those that do, a modal-style file explorer window will open listing the files inside as a grid.

Selecting an individual file opens the program to which it is attached, filling the entire screen. OpenOffice, for example, would display as you would see it on a desktop.

Unlike a tablet or smart phone, there is no centered 'home' button or icon to immediately indicate how to exit the current screen.

I feel for the modal-type screen, a centered 'close' button is more clear and effective, as there are no other buttons needed for those modals. There are no other possible interactions other than select a file or close the window. The current modals use a top right x and are displayed very similar to Windows 7 'windows'.

The programs that fill the entire screen are all OpenOffice or similar and, of course, also look like the Windows 7 windows with the x in the top right corner, which is normal for programs of that type. These programs are not as often used, but when they are used, the mouse is almost always used to interact with them, which makes selecting the X in the top right corner much easier to target since they aren't using their fingers.

Does it confuse the user or break the user experience if the file explorer modals are closed with the 'close' button (without an x to close in the top right corner), and the program windows are closed with the X in the top right corner but no close button?

Update to add pictures of screens

Most screens on this devices are going to be panels for settings or grids of items to select. Those screens, in my opinion, would be effectively closed with a button like so:

screen panel with center close button

The few programs that users have access to that act like word processors or spreadsheets, I think should close like so:

spreadsheet style windowed program with top right close

I don't feel like they have to both close the same way, because of how they are used.

  • why do you want to sometimes NOT have an x top right? what is the benefit of not having it? also the modals should be possible to close with ESC in my opinion – Aprillion Apr 17 '16 at 18:33
  • @aprillion I updated the question with images to demonstrate why I think different windows/panels don't need to use the exact same closing function. Also, I hope the windows can close with escape, but since this device is neither computer nor mobile device, I can't guarantee that. Much of the functionality is used via touch screen. I'll pass this suggestion along to the software engineers, though. – Maigen Thomas Apr 18 '16 at 18:31
  • I still don't see how you don't need the x in that pop-up dialog.. there is just the right spot on the top right for it – Aprillion Apr 18 '16 at 18:51
  • Because there's a difference between 'need' and 'there's a spot for it'. I want a clean user interface, and I don't feel like it needs two different ways to close a panel that is 6" x 3.5". – Maigen Thomas Apr 18 '16 at 18:56

This sounds less like a question than you publicly stating why your decision is justified. That's usually a dangerous position from which to design a solution.

In experience design “simple” ≠ sparse

In the comments you expanded on your concerns:

I want a clean user interface, and I don't feel like it needs two different ways to close a panel ...

This is a matter of "clean" aesthetics. You can take an aesthetic-centered approach, but don't pretend that aesthetics and experience are directly proportionate.

If users expect a close button in the top right to facilitate a "cancel" action, they don't care if it looks better to remove it. If you do remove it, you'll likely end up with a bigger button at the bottom to retrain them. Bigger buttons rarely look "cleaner".

Test your assumptions

Everything I've said is speculation. Speculation grounded in experience, but it's a guess nonetheless. The only way you'll ever know if your audience understands an inconsistent approach to closing things is if you test a representative population.

Bit hard to say for certain without some images to go with your scenario.

It's generally a good idea to maintain consistency for common actions, such as close. If you're using apps like OpenOffice, it's probably fair to assume your expected behavior is frequent (e.g., people use the devices regularly). So, I'd expect people to habitualize common actions such as close over time. If close keeps moving around, then they can't create that consistent cognitive model and it'll be frustrating over the long-term.

That said, there are reasons why you might want to break consistency to force a different thought pattern or more deliberate choice.

Ultimately, usability testing and such with people that will actually use the system is the best way to validate your decision (preferably in an environment similar to the expected "real life" situations). Given what I've seen in previous tests, I'd recommend consistency in most situations like this.

  • Hi josh, I added some images to better demonstrate what I mean by the different windows/programs. I agree with the habituation of certain behaviors, but I feel those habits are formed by interaction with types of programs/windows - certain things are expected of one but not the other and vice versa. What do you think? – Maigen Thomas Apr 18 '16 at 18:33

    I agree, the difference in close techniques is probably fine here. You could add an "x" on the dialog as well, then track to see how often it's used vs. the close button at the bottom of the dialog... but, that's overkill in my opinion. – josh Apr 18 '16 at 23:53
