Imagine how I felt when I was sitting at my desk, Nexus One in one hand and pen in the other, after being asked to design doubleTwist’s media player for Android. Android doesn’t have a very nice media player in terms of design (I’m carefully picking my words here – I don’t want to offend the undoubtedly hard working people at Google) and it was easy to just go the way some developers go: make an iPhone app, shoehorn it into Android, and call it a day.

We wanted something that actually advanced the state of the art. I sure as hell wasn’t going to use an entirely new platform for months just to ape another. It was a mixed blessing to have so little limitations on what constituted a ‘native’ user interface.

Android has its guidelines, but most apps (even the Google-sanctioned Twitter app) have a very ‘custom’ appearance. We opted for a look that works well on the various devices and custom ‘shells’ (notably, HTC’s terrible “Sense” interface) and arrived at this muted, native-looking yet polished visual scheme, which also helps users navigate the app in direct sunlight, where OLED screens like the Nexus One’s tend to be hard to read. Subtle usage of textured surfaces in the application also help prevent color banding on the color-limited OLED screens.

I’m happy to have this in the hands of Android users. It’s sometimes depressing to read comments on tech websites of people exclaiming: “Why would you even care about how a media player looks or works? You play music and turn off the screen!”, but I am sure there’s a lot of people who will appreciate the thought and details that went into this app. And that makes it all worth it.

The player is available on the Android Marketplace for free for a limited time.

However, the part I disliked about Steam on the Mac is the (understandably) less-than-native looking and feeling UI. While the entire application was recently redesigned (and re-engineered to utilize Webkit as its rendering engine), it still feels less than at home between the system apps.

As a fun exercise, I’ve redesigned Steam in a way that maintains consistency with its own UI conventions and values, while changing look and feel to make it more native to the Mac platform.

You can see a comparison between Steam for Mac’s UI and my redesign on flickr here.

I won’t tease you with only vapid mockups, though. While you’re here, grab my Steam replacement icon for OS X.

Of course, if you have input on the mockups, sound off in the comments. Meanwhile, I am currently considering sending my thoughts to Gabe for further consideration.

As usual with a large Apple product launch, I’ve written up this post to round up the good, the bad, and the ugly of all the new interface and interaction designs that were set loose on the world by the company that’s regarded as the most influential and skilled when it comes to designing experiences. The usual disclaimer applies: iPad hasn’t hit the market yet, and thus its UI may still be subject to change or improvement.

Man, where do I begin. iPad’s made a huge step from the small and cramped iPhone screen to a crisp 1024 by 768 pixel screen, and instead of going down the road of iPhone’s (or Mac OS X’s) rather sterile and conventional interface designs, uses very ‘earthy’ metaphors that behave like their real-life counterparts. This allows for most, if not all of the conveniences modern interfaces we know from our desktop computers while retaining ease of use.

Let’s start with the home screen, then, and thus, its icons. Ah, icons. The traditional iPhone icons have taken a small step up on the iPad homescreen, to 72×72 pixels. This wasn’t public, but you can calculate this from press images. For Spotlight, the search interface, and the Settings application the icons are scaled down to 48 pixels. The same shape, gloss, shadow and lighting is used for the icons on iPad. This does help a consistently looking platform, but I’m not out on the extra spacing of icons on the home screen yet. They all look so lonely in there.

What you’ve heard here first, though, is that iPad’s OS also houses as-of-yet unused 64 and 320 pixel document icons, which makes me eager to see how the ‘filesystem UI problem’ will be solved by Apple. Obviously, iPhone OS was a great way to re-imagine computer interaction from scratch, and the whole hierarchical filesystem that confused and confounded users for so long was left out in the cold. The new and simple method was to use automatic saving and persistent data – but with iWork on the iPad as a serious content creation platform, this isn’t an option anymore. I’d love to hear people’s speculations and ideas on how Apple could solve this.

Globally, when compared to iPhone, the biggest obvious change is the relocation of toolbar buttons and controls. For iPhone, crucial controls and toolbars are placed at the bottom, where they’re the easiest to reach with your fingers when held in one hand. The iPad disregards this somewhat, and uses the desktop toolbar model. iPad’s Safari, for instance, has all its features accessible through toolbar buttons in the top toolbar:

Sometimes controls go on the bottom, though. It seems to vary from app to app, much like on Mac OS X. Interfaces overall are much more tactile though, as I mentioned in the introduction.

iBooks, for instance, uses an interface similar to the one me and David designed for Classics for iPhone. Since it got a bit of hubbub due to the (obvious) similarities, Classics is now free. I encourage you to grab it; it’s still as great an app it once was, but iBooks is certainly how we’d envisioned it to be if we had unlimited engineering power.

When you tap to switch to the iBookstore, the entire shelf rotates around and shows the store layout. Upon buying the book, the book’s cover moves toward you, the shelf rotates again and the new book gets neatly placed on the shelf, rearranging the other books automatically, and gets a nice blue ribbon to indicate its unread status. As you may expect from such extremely elaborate animation design, picking a book animates opening the book. Every single action is animated to allow for natural interaction with it.

When the discussion of electronic books comes up, people always mention the emotional connection with the feel and look of a real book. Nice typesetting, the sound and feeling of turning the pages are all big factors in this. While iBooks is not a replacement of a real book, I believe it’s certainly close enough – with the added convenience factor of having thousands of books in a device as thick as a magazine.

The natural metaphor of books is reused throughout the OS, such as in the Contacts application and the calendar. Contacts, with its index list of all contacts on the left hand side, doesn’t have page flipping, but the Calendar might. I’ve only seen it being navigated using the tiny arrows at the bottom so far, though, so I assume it doesn’t allow for this type of interaction.

Other touches of animated interaction are equally amazing. Instead of tapping a button to curl up the edge of a map in the Maps application, you actually flip the edge over yourself. When selecting emails, they all get thrown on a stack. Deselecting an email in the stack curls up the top email and sucks the deselected email back into the list. Speaking of stacks: Photos actually has little stacks of photos that you expand with tapping or pinching.

Photos also takes the scrubbing we’re familiar with from iMovie and iLife (see also: my iLife UI roundup) and applies to it to a photo album, to allow for easier and visual navigation of images. I think it’s a nice interface element, and much more efficient than Coverflow, which seems to be on the way out at Apple if you look at iPad’s conspicuous lack of it (it seems to have stuck in the App Store – no other sightings, though).

The note-taking application is still a bit of a gimmick playground. The font is still Marker Felt, which hampers legibility somewhat, and instead of a regular selected state, it appears the currently active note is displayed with a red outline in the source list on the left. It’s a friendly touch, but I feel like it’s a bit unconvincing and forced.

The Calendar application looks very nice and seems to be functionally awesome, but the corkboard texture is drab from a distance (I am not sure how this looks in the flesh). The amount of rethinking that’s been put into the calendar makes iCal on Mac OS X look rather bad, though. It looks like the best calendaring app I’ve seen so far.

The movies application is surprising and pleasing in its simplicity and amazing in its animations: movie covers fold out like a DVD to show chapters, information, and artwork, and let you play back with a simple tap. It’s gorgeous, top-class design, and so simple and obvious that it’s hard to imagine something that could do a better job at presenting information to allow the user to pick a movie to watch without getting in the way.

iWork for the iPad is interesting: it’s a first in a series of serious applications that you can use for ‘production’ work on such a device mainly geared towards content consumption.

Keynote has a black toolbar with its features accessible through popover inspectors. The presentation view lets you use a faux laser pointer (a neat touch) or draw over the slide to highlight an item. Its desktop interface was already amazing, and they’ve kept it practically intact for the iPad.

Pages and numbers, however, get makeovers in the UI department, making some things a bit more simple and graphically pleasing. Pages, for instance, has a formatting bar that slides out from under the main status bar that lets you manipulate text-editing parameters.

I think I’ll spend more time dissecting the iWork UI once it hits the shelves: there’s very little of it to be found in the galleries and movies of Apple.

The pinch gesture seems to be used a lot more in the entire UI: in Photos you expand grids with it, but you can also go back up the hierarchy by pinching out. The same can be done in books. It’s similar to what Palm did in WebOS: using universal gestures for the hierarchy navigation. Fortunately, Apple still makes going back in the hierarchy discoverable with the regular ‘back’ buttons on the top left, which remain usable. I do like the idea of using gestures for quicker navigation, which is starting to become necessary with such a big screen.

The departure from the pinstripes and blue bars of iPhone OS is something that I’m quite happy with, as it’s the first part of the iPhone UI that has started to look rather dated. In the interface of Mac OS X, the pinstripes were gradually phased out, and perhaps the same thing is happening to the iPhone. Who knows if we’ll see iPhone OS 4.0 introduced at WWDC this year with new ‘metallic’ status- and toolbars and no more pinstripes. I’d be quite happy with that.

Neat touch: the full-size keyboard of iPad has actual tactile ‘nubs’ on the F and J keys, like a real keyboard.

Another neat touch: the (surprisingly bare) iPad lock screen has a little button next to the unlock slider that turns the iPad into a photo frame.

Source lists, as we know them from desktop interfaces, are basically iPhone tableviews on iPad. I’m sure this works nicely, but the way the iPad interface represents them is very detached. In the Settings application and the Mail application, for instance, they are contained in their own ‘view’ of sorts, with rounded corners and all.

It makes me wonder why the list isn’t simply ‘attached’ to the content on the right. This feels a bit like the iPhone interface elements have simply been shoehorned into a large screen UI. To add to this, in portrait orientation these iPhone-like lists are incorporated into a new UI element called the ‘popover’, where it contrasts harshly against the dark blue. It looks a bit kludgy.

Another tiny nitpick: the tab controls for picking datasets or application modes have an inconsistent active state. When the UI is dark, the active tab is lighter than the other tabs, and when the UI is light, the active tab is darker than the other tabs. I’ll have to see how well this looks on the actual device.

Spotlight is also interesting. While all search fields on iPad go on the right-hand side, Spotlight’s search field is in the middle, since it doesn’t really have an application to go with it. The search results themselves go into a narrow column that doesn’t fill up the entire screen. It doesn’t look as polished as the rest of the OS, in my opinion, and the icons seem rather large. On the iPhone, the icons are as high as one row of search results, but on iPad the icon spans about a row and a half.

The first thing in the keynote that punched me in the face with its repugnant and inconsistent appearance was the iPod application. It resembles a bastard child of the iPhone’s iPod application and iTunes of the desktop, but fails to really take advantage of the innovations either has made. It’s full screen mode is particularly disturbing, which you can see in this image:

Really, Apple? I can see myself looking at lyrics, but can you imagine using your iPhone to listen to music and having round blobby buttons to control playback instead of a clean, glyphic overlay? I’d let it go if it was consistent with the general control layout of the main application, but those are positioned entirely differently. Let’s hope this one is still in development.

The icons of iWork and iBooks are rather bad, as well. iBooks simply has a strange combination of a glyphic symbol and a strangely textured background, while iWork’s desktop icons were placed into an icon roundrect without too much change. The Iconfactory’s solution to this for their iPhone-like desktop icon set ‘Flurry’ was much nicer.

iPhone apps can run on iPad without issue. They actually get a nice little iPhone-like frame when running at 100% size (i.e.: not blown up to the screen size).

I’m worried, however, of displaying them at this magnified size. They’re blown up to twice their regular size, which wouldn’t be a problem if the iPhone encouraged resolution-independent interface design, but almost all iPhone apps use custom controls that are designed at one size. Blowing them up will create a blurry mess of pixels. I’m curious to see how this problem will be solved – if it will be solved at all, of course.

And as a last ‘meh’: the contacts application doesn’t seem to adapt well to a portrait orientation. The book is simply scaled down from the landscape mode, and it feels rather inefficient. This is obviously a trade-off to make the UI still look natural instead of like a terribly elongated book, and I hope it’s being worked on, but regardless, it looks a bit suboptimal.

Fortunately, there’s not that much stuff in the iPad UI that I’d call ‘bad’ or ‘ugly’. Apple has shown once more that they’re at the top of their game, and the interface is sublime. If iPad had preceded iPhone, we’d all be lyrical and hopeful for a smaller device that did even a few percent of its awesome feature set. Instead, this natural evolution of the iPhone OS is being heckled by people that fail to see how extending the underlying ideas of iPhone’s UI helps interaction with ‘serious’ applications like iWork.

This was by no means a full UI roundup: as usual, there are parts I may have missed or overlooked. Feel free to add your observations in the comments. I hope to document some of the most subtle interaction and UI design finesse Apple put into iPad once I get my hands on the final product.

Check back in a few days for several Photoshop files to help you create pixel-perfect mockups of iPad interfaces, a free part of my Icon Resource design resources which will soon feature full lessons on iPhone and iPad interface and icon design.

Here’s a brief a look at the new Icon Resource – and its new brother, iPhone Resource. There’s something new for previous and new members in the works, but I’m not ready to release it yet. This only means that there’ll be that much more content for you if you’re a member: two entirely new courses on Mac / Windows icon design, including intermediate and advanced techniques.

iPhone Resource, a separate and new set of courses, focuses on making amazing iPhone icons and interfaces. It’s shorter and more concise than its big brother, but from what I’ve seen in the App Store, it’s certainly sorely needed.

You will also get a brand new member area, where you can watch course videos, review lessons and download files. An iPhone application is also in the works, but I can’t tell much about that yet. It’ll be released a bit later than the actual upgrade.

Much design love went into this new version, and all pages have been redesigned from the ground up. The new login page went through over a hundred iterations. Click on the image to view it at full size on Flickr.

I expect to roll out the entire new Icon Resource upgrade in late February or March. As an existing member, you will be notified by email (and only this time! I hate newsletter spam) when the new content arrives. The price will remain unchanged.

However, I won’t be doing a lengthy post on its design process this time around. Instead, I made a video in which I tell you a bit about the process and show off some timelapses of the game graphics and icon. Consider this an experiment, and let me know what you think!
