I’m very interested in iPad used for content creation, you might call it “casual content creation”. With iWork for iPad, Apple sent a clear message: the iPad is more than a content consumption device.
I believe content creation apps are going to be key to the iPad as a platform.
The competitive strategy angle is that HTML5 is narrowing the gap, so much so that a content consumption web app can come pretty close to a native app. However for key content creation aspects like interactivity, integration with the system, media richness, speed, disconnected use and polish, native apps still have an edge. This means that native, content creation apps, differentiate the iPad from (upcoming) competing tablets, more than a content consumption app can do.
The platform strategy angle is that content creation apps complete the iOS platform and, in the context of the laid back/feet on the table target, make it general purpose.
Content creation on a touch screen is a shocker to people who believe you’re only creating content when you’re typing text—how could you type all the text on a soft keyboard?
Once you overcome the concept of keyboard and mouse as the primary input devices, you realize they might in fact have been a blessing and a curse, stifling creativity by forcing tools and users to adapt, instead of the other way around. What would music sound like today if we had never evolved from harpsichord and lute, would Mark Knopfler play Sultans of Swing on a harp?
The basics of computer literacy today involve learning to coordinate eye and hand to internalize the separation between hand movement and on screen activity. Change your mouse acceleration settings and realize just how delicate the abstraction is.
To a novice user, aiming at something on screen with a mouse is like trying to ring a doorbell using a broomstick. The tool that’s between you and the target object is the cause for the lack of directness. You will get used to it out of necessity, but that doesn’t make it better than direct interaction.
To sum it up, a first level of indirection is removed by touching objects on screen: you directly touch and manipulate information you want to act upon.
This is a tricky one. Twenty six years of Windows Icons Mouse and Pointer leave us with conventions, behaviors and encrusting that build on input device limitations in ways that make user interfaces hard to learn.
Object selection is one of the relics of WIMP interfaces, the selected state is a form of intrinsic UI modality. Objects and actions are pleasingly orthogonal to the mathematically inclined, but performing actions on objects that are in a selected state is another form of indirection, akin to using a marker to highlight the Lego brick that you’ll then pick up with your “hand tool” to perform an assembly action.
Selection is the premise to the Great Inspector Hunt, whereby you click on an object to manipulate it and then go to an entirely different place to hunt down the property you’re looking for.
Despite the trend to simplify user interfaces and remove features, there still are too many features to expose only through gestures, particularly considering the lack of a shared gesture vocabulary among different apps.
Multiple selection is a common UI feature that doesn’t map well to touch screens, and in fact it doesn’t really map well to some kinds of objects even on the desktop, like discontinuous text selection. Multiple selection also prevents contextual UI placement, which I believe to be a problem of multiple selection, not of contextual inspection.
On a touch screen the two “obvious” ways of implementing multiple selection are the iWork way, tap and hold first object then use other hand to tap other objects, or the desktop-inspired drawing of a rectangular “rubber band” that selects all objects it touches. Multitouch with two hands is a pretty demanding technique, let go of the first object and you lose the selection, the first hand partially obscures then screen and is in the way and you really have to put the iPad down. Dan Messing’s otherwise excellent FreeForm drawing app implements rubber band object selection, the fundamental downside is that because there’s no hovering mouse cursor and because the entire canvas is a target that initiates a rubber band, it is exceedingly easy to activate accidentally, deselecting the object you’re working with.
The solution is to think about what multiple selection is really needed for and try and do that differently. Text style can be applied to multiple objects by copy/pasting style information, Keynote on iPad uses a suboptimal multi-hand gesture to match object sizes that is essentially style cloning. Mail on iPad groups “objects” by entering a mailbox “edit” mode, where multiple messages can be selected to be moved or deleted. There likely are other workable solutions that can contribute to kill the need for multiple selection.
So while from a software development point of view you can still think of an object as being selected, from an interaction design point of view it probably helps to think selection doesn’t exist, that by tapping an object the user is asking for the object manipulation UI to be exposed. Near the object of course.
When you approach a building you don’t type in the door angle in degrees to open it. Sometimes the door handle shape doesn’t match how you actually use the door, but you definitely manipulate the door directly.
Yet app use generic number or string editing controls all the time, instead of meaningful visual metaphors. User interface kits of standard controls help developers build apps faster, at the cost of seldom representing object properties in a way that directly manipulates the property.
The lack of directness, result of the use of a surrogate representation, might have been a reasonable compromise between immediacy and implementation simplicity in the past. Today it’s just forcing the user to think in terms of the app’s representation of a property, rather than the property itself. So, once again, it’s a form of indirection that should be removed.
Fixing this is very dependent on the kind of property, and there’s a tradeoff between frequency of use of a property and clutter when all the property controls come on screen.
A landscape touch screen makes for a surprisingly functional keyboard, considering it gives no tactile feedback. Clearly it is no match to a real keyboard, if your job is to crank out a few pages of text a day you’ll obviously want a real keyboard and perhaps a full desktop OS.
But actually if you are a gifted writer and can dump your brain and turn thoughts into actual textual content in an unretouched stream of words, the glass keyboard might be reasonably usable. The issues become apparent when you need to edit and move text around, to manipulate text instead of to produce content. Moving the cursor around with arrow keys or using keyboard accelerators to manipulate text, like hand-eye coordination in using a mouse, is second nature to anybody who spends any amount of time typing.
Beginners will instead just backspace through perfectly good text to get to a typo, until they learn the magic of the left arrow key: it’s like a backspace that doesn’t delete!
This is not to reiterate the “iPad is for young/old/dumb people” cliché, rather to point out that keyboard-based text manipulation is not a natural interface, that we should consider the idea that there might be alternate interfaces for text editing, that function and meta keys that have popped up over the decades are barnacles on the “content keys” rock.
A new interface for something so fundamental isn’t something you dream up without testing and I haven’t given it a huge amount of thought, but I do believe that a keyboard-less multitouch text navigation and manipulation UI might be a workable solution, better than trying to replicate keyboard and mouse based manipulation on a multitouch screen.
The iPad is sexy and makes you want to use it even for content creation. In a future article I plan on discussing how the above applies to the iWork UI, though it’s clear that iWork is just a first good shot, definitely not the final word on touch content creation UIs.
I believe content creation apps will define the iPad and make it many times more useful than it currently is, and I believe only UIs that remove indirection and bring content closer to the user will succeed in disappearing, as Adam Engst puts it “the iPad becomes the app you’re using”.
You shouldn’t write off the iPad as a content creation tool just because iWork isn’t quite there yet. Remember the state of Mac software on January 24th, 1984? Yeah, MacWrite or MacPaint, one at a time. And the Mac was born for content creation, as most dead-tree-age, printer-front-end solutions were at the time.
I’m at WWDC for a few more days, so if you’re in San Francisco I’d be happy to chat about this, just contact me @duncanwilcox.

I am curious about how “real apps” will work on the iPad, how an application that is more than a utility or casual/light use exposes functionality in a touch-optimized user interface.
The only available information is what Apple has shown at the iPad announcement on January 27th. We will surely discover more soon, but I wanted to get a head start and, well, couldn’t help watching the keynote a few times and grab all available footage from the post-keynote hands-on.
I assume you have probably seen the section of the keynote where iWork is shown, if not you can catch up by watching just that part, extracted and cut by Luke Wroblewski. Fraser Speirs also discusses the screenshots of iWork apps as seen in the keynote in his article iPad Fallacy #1: “It’s not for content creation”.
Many of the interactions are pretty obvious on the surface, but on a second (or third) look reveal the non obvious or the unexpected. So here’s a quick rundown of what I have found, mainly in the iPad version of Keynote, Pages and Numbers.
A lot of the UI and interaction that wasn’t shown on stage is visible in the hands-on videos. It is interesting and sometimes hilarious seeing the Apple representative stumble into features and expose the difficulties as he or she learns the UI, sometimes even failing to discover the proper gesture — notably how to exit a Keynote presentation in the endgadget hands-on video.
Many thanks to engadget, gizmodo and gdgt for their pictures of the keynote and Slashgear for their detailed hands-on video.
A slight indentation of the slides in the outline on the left in Keynote could seem just a visual representation of hierarchy, it actually is a fully functional outline with collapsible sections, note the disclosure triangle.

In two instances in Keynote popovers and UI persist in-context (next to content) only when in a mode explicitly entered and exited by the user, which seems like a reasonable rule to follow.
Transition build popovers
Image masking in-context controls
There are inconsistencies in how UI modes are entered in Keynote. Slide reordering mode is entered by tapping and holding a slide in the outline, transition setup is entered tapping the corresponding menu icon, image resize mode is entered double tapping an image.
Pictures, charts and shapes can’t be dragged out of the “insert object” popover, so in Keynote the new items are just lumped on the slide. The inability to drag is inconsistent with press-and-drag to reorder slides on the sidebar and while we don’t know what pressing and holding does, I’ll guess that since a single tap inserts the image, pressing and holding has no effect. The reason for the non functional drag and drop might also be related to the modality of popovers.
Attempt to drag an image to the slide fails
Reordering columns in Numbers doesn’t appear hard to perform, but I feel like it’s nearly impossible to discover that you have to tap exactly on the column header to select it, then tap and hold to drag it.
Dragging columns in Numbers
I haven’t found any footage of pictures or charts being deleted (or slides for that matter), nor any UI that could be thought to perform deletion, and the Apple representative in the Slashgear video solves it by repeatedly pressing the (prominent) undo button. This could either mean it hasn’t been implemented, or the delete gesture isn’t all that obvious.
Reaching for the visible Undo button
Multitouch is one thing, multihand a whole other, it doesn’t look at all comfortable and Phil Schiller actually had to put the iPad down when moving multiple slides and when matching image sizes in Keynote.
Multihand multitouch. Ouch!
The inspector icon always shows the proper inspector for the selected object, in this case text. Aside from the questionable, arguably not-keynote-ready design, the text inspectors scream incomplete! There are text styles, but where is the text style editor? Where’s a font picker? How about a color picker? These are UI elements we take for granted on a desktop, and they are necessary for content creation. Clearly they’re coming soon.

Here are screenshots of things I haven’t seen elsewhere.
Pressing the bottom left + opens the “Tap to insert a new slide” popover, tapping on one of the theme-preset slides animates it to the center of the screen.

Even though the popover arrow points to the left, the tools menu appeared after pressing the wrench icon. I didn’t expect to see “Find” or “Help” in here. The last two items are “Slide numbers” and “Check spelling”.

In conclusion, is the iPad going to be a good platform for productivity apps, apps that go beyond content consumption? For the time being I will have to answer with a conditional yes, despite Phil Schiller insisting that you can do “really advanced” things “with just a finger”. I feel like Apple is stil figuring out the UI and iWork will likely be a little different when it ships.
The overarching problem seems to be that finding a place for UI elements and finding a way to interact with them is a new science and needs new conventions. Additionally gestures aren’t always easily discovered even when they are consistent across apps, but the lack of conventions leads to non-uniformity which makes it even harder. The best bet here is following iWork’s behavior as much as possible.
I will say that the iPad is going to be good enough for “casual content creation” at the very least. Given time and research and experimentation with touch UIs, it definitely feels like it has the potential of eventually replacing desktop UIs for many tasks.
