Planning for change

Tuesday, August 25th, 2009

This sort of thing always worries me. I really wish we had a more formal way of alerting users that functionality was going to go away, rather than just pulling the rug from under their feet when they install a new release.

At Sun, and I’m sure at most other companies that support software products, we have to tell our customers in advance when (certain) features are going away. We can’t just drop them from one release to the next because we’ve gone off the idea.

Personally, I’d like to see GNOME manage this a lot better, perhaps (from the end user’s perspective) via a section in the GNOME release notes that said which features we intended to remove from the next release. The impact of such changes would then have to be thought through well in advance, and there’d be plenty of time to remove the feature, fix any related issues, and properly update the documentation prior to its actual disappearance. And users would have time to prepare for the change, and have the opportunity to raise any sensible objections before the fact, rather than after it.

(This thought isn’t especially new, nor directly aimed at the proposed Windows capplet removal… although I do know that’s a decision that would generate support calls for Sun users and customers, who always scream when anything related to their sloppy focus settings breaks, changes or goes away. Many of them have been using sloppy focus on UNIX desktops since before GNOME or even Linux were first thought of, so it’s not a feature we like to mess with…)

Control Center Refresh redux

Monday, August 17th, 2009

Quick follow-up on my last post about some ideas for a GNOME control center refresh.

Kristin and Jenya are running a usability study on three control center designs in the Sun labs this week (current GNOME control center as a baseline, plus two of their alternative designs). There will be 10 participants over three days, a mixture of “developers, technical end users, and technical students”.

We will of course share the results as soon as we have any to share :)

Control center refresh

Tuesday, July 14th, 2009

Some of you have probably heard that some folks at Sun have been working on a proposal for a tidied-up GNOME control center shell. Well, at long last, here are some details!

First of all, I should say that I actually have little personal involvement in this project—it’s being led by Kristin Travis and Jenya Gestrin of Sun’s xDesign team… I’m just abusing my position on Planet GNOME to plug what they’re doing :) And as yet, there’s no production code to speak of, just mockups and Flash prototypes, so there’s still plenty of scope for feedback.

You can download the latest protoypes, peruse numerous mockups, and read about the design process to date (including a usability study on the capplet categorisation) on the Usability Project’s Control Center Whiteboard pages.

gnome-shell on OpenSolaris

Wednesday, April 29th, 2009

Kudos to Brian for getting gnome-shell up and running on OpenSolaris—since I’ve barely touched a Linux distro in the past year or so, this has really been the main thing that’s been stopping me from taking a proper look at it, and getting involved in what’s clearly going to be an important part of GNOME’s future. I guess I don’t have any excuses now :)

Twitter Bowl

Some nice Twitter visualisation from the NY Times. (Although the score doesn’t seem to update as it ought to, in Firefox at least.)

Different day, same Places

Monday, January 12th, 2009

A couple of years ago, I bemoaned the inconsistency of our presentation of bookmarks and places.

Last week I had cause to revisit the issue (for much the same reason as before—updating the OpenSolaris UI spec), hoping that things would have improved and I wouldn’t have to suggest too many tweaks to the OpenSolaris layout to keep things nice and consistent.

Unfortunately, it doesn’t look like much has changed though, really, which is kind of disappointing. (Especially as seeing this bug marked as resolved had built up my hopes a little…)

Caveat: as in my original post, the latest release of Ubuntu (8.10, GNOME 2.24.1) was the closest I had to a community build when I was doing the comparison. So things may really be a little better or worse than they appear here, or may have been fixed in 2.25/2.26.

So I hacked up a quick diagram showing all the menus and sidebars where bookmarks and places appear, and aligned them on the “Home Folder” entry since that was about the only one that was consistently placed. Here’s what I came up with:

Side-by-side comparison of bookmarks/places in Ubuntu 8.10

Side-by-side comparison of bookmarks/places in Ubuntu 8.10

The plusses:

  • The two Places menus on the panel (one in the menubar applet, one in the main menu applet) are now identical, at least in Ubuntu. This is good to see, although most users won’t see both at the same time anyway.
  • The Go and Places menus in Nautilus (browser mode and spatial mode respectively) are pretty consistent with each other too.

The minuses:

  • Inconsistent appearance/placement of mounted media, Computer, Desktop, Templates, File System, and CD/DVD Creator between sidebars and menus.

Of course, it would be wrong to complain without offering any proposals, and I’ll get to that—just haven’t got time today. The current draft of the OpenSolaris 2009.04 UI spec does include my first quick attempt, but that’s currently based more on “least amount of work to fix” rather than “what might be most useful”… and we all know that’s not really the way to do it, right kids? :)

End of an era…

usability.gnome.org is no more.

Well, okay, that’s not quite true :) The old developer.gnome.org sub-site it redirected to is no more, because all the content has moved, mainly to the Usability Project wiki. Hopefully we’ll get some new redirects in place soon.

This has left the online version of the development branch of the HIG without a home (the stable version, of course, moved to library.gnome.org a while ago). So for now, I’m hosting that here.

EDIT: D’oh, seems the development version was already online too, at http://library.gnome.org/devel/hig-book/nightly. I’ll dump the version from my homepage shortly.

On the new shell

Monday, November 3rd, 2008

It’s great to see Vincent, Owen, Federico, Karl et al. thinking about bold ways to bring the GNOME desktop into the 21st century.  With guys like that motivated to make it happen, we certainly have more than a fighting chance.

But despite taking a keen interest in GNOME usability for the thick end of a decade, I haven’t specifically commented on any of their mockups.  Why not?

Because if we’re serious about this undertaking, now isn’t the time to debate the merits of major design changes among ourselves. It’s the time to go out, talk to our users, watch them using GNOME, and work out what needs to change, what might be cool to change, and (just as importantly) what needs leaving alone. And that’s before we even think about making any more mockups.

And when I say “our users”, I’m not talking about the usual suspects here, either.  I mean the silent majority who don’t show up at GUADEC, don’t hang out on mailing lists or IRC, and don’t file bugs.  The ones who might not even use GNOME through choice, but might just have got out of bed one day to find it’s been installed on their office or school computer, or on the kiosk in their library.  And the ones who don’t even know they’re running GNOME at all, but who just know they have some desktop or mobile device that doesn’t look exactly the same as Windows does at home, but that it kind of works the same.

With all due respect to those who’ve put their ideas on the line so far, making visionary mockups of a brave new world isn’t usually all that difficult—although it’s certainly fun :) Making mockups that meet well-researched, documented user requirements takes a bit more effort, though, and refining those mockups into a product based on iterative feedback from a representative sample of users is, well, a lot of hard work.  You only need to look at the amount of software that sucks for proof of that.

With that in mind, let’s do it!

(FWIW, I did some further waffling on this theory in my response to Stormy’s mail on the usability mailing list recently.)

HIG 2.2

Friday, September 26th, 2008

I just bumped the stable version of the HIG to v2.2.  

Really it’s more of a 2.0.1 release, as none of the content has changed apart from the illustrations, which have all been updated to use the Clearlooks theme.  But given the number of people involved (Mihai Anca, Denis Anisimov, and Wouter Bron did the bulk of the illustrations) and the length of time it’s taken me to integrate them (about 9 months!), 2.2 seemed more appropriate…

(Unfortunately, nowadays you don’t get to see new versions of the HIG online until there’s a new release of gnome-devel-docs, and I know I just missed 2.24.0. But hopefully there’ll be another one along soon.)

Of course, this doesn’t address the more fundamental issue that the HIG now lags several years behind the curve of GNOME development. I’d like to think we’ll get around to doing something about that before the year is out.

Tab frenzy

Friday, July 11th, 2008

Have to admit I cringe every time somebody adds tabs to an application. Not because I have anything against appropriate use of tabs (and I’ll reserve judgment on which of the recent additions are appropriate for another day), but because it’s such a wasteful duplication of effort, with each instance doubtless having its own inevitable little bugs and inconsistencies.

The HIG advises against document-level tabs in an app, largely because at the time, the usability team hoped GNOME would have a tabbed window manager in its not-too-distant future. The tab-related activity in the past week has me thinking me that we need this more than ever! App developers shouldn’t have to implement basic window management features, and (perhaps more importantly) users shouldn’t be restricted to grouping documents from the same application into tabbed windows–with a tabbed WM, they could still do so if they wanted to of course, but they’d also be free to group windows by task or project, or indeed any other way they wanted.

Is it worth starting to think a bit harder about how a tabbed WM might work (I don’t think we’ve ever sat down to try to design one for GNOME, although I know at least one tabbed WM has been implemented before)?  Or is it just something that’s just never likely to happen?
