What is mobile?

Ah, technology

These are...

And these...

Are these?

More on the way Left to right: Windows Phone 7, Kin, Nokia Morph Concept

Know the hardware

Form Factor Best Buy makes a great device lab.

Other capabilities GPS, accelerometer, microphone, light, camera... Applications from left to right: iHandy Level, Stickybits, Square

Human Factor Left vs. right handed, proximity of reach, fatigue...

Connected?

Define the app

Not a scaled down website ≠ Option + “=” on a Mac will give you a ≠

Web app vs. native Left to right: Twitter Mobile Web and Tweetie iPhone App

What’s the soul of the application?

Primary touchpoint? Mobile is the main source of traffic. Applications from left to right: Ramp Champ, Convertbot

Companion Mobile app augments other experiences. Applications from left to right: Starbucks, iHome

Optimized UI Same functionality but in an optimized way. Applications from left to right: Evernote, Gowalla

What’s the use case? How, where, when is an app going to be used? Who is using the app? Image via mindingthegaps.com

Be clear on the use From icon to user interface AOL Radio

Mobile informs Mobile apps can be a test bed for new features in other experiences. Design mobile first.

Where are people coming from? What’s their technology ecology? iPhone? Android? Mac OS? Windows? Laptop?

Think about design

Consider brand Chipotle

Consider the whole experience There’s more than the UI. There’s the icon, startup screen, app store screens, etc.

Native UI vs. Custom UI Left to right: Wordpress, Epicurious

Understand the different platforms Android, iPhone, Web OS, etc. all have different UIs

Review the HIG and other design guides

Make it touchable Areas of interaction need to be big enough to easily interact with.

Orientation Design for the best experience in different orientations.

Promote the primary Eliminate extra noise by subduing secondary actions.

Rethink the metaphor ★ Metaphors can create a shallow learning curve, but aren’t always appropriate ★ Use metaphors that make sense ★ People are coming from the web if not from another device

Think affordance How do people know to interact with things?

Use default gestures ★ People enter with different gesture vocabularies. ★ If you’re not sure, go default. ★ You may be competing with other apps. Image via Touch Gesture Reference Guide on lukew.com

iPhone vs. iPad

On-the-go vs. on the couch. Iamge on left via iLounge.com

View from all sides Unlike a laptop, an iPad has no flip up screen to block interaction with others. Scrabble image via engadget.com

Wide open spaces Things can get lost on larger screens. More space means more chances to get lost.

Focussed views Each screen has its own purpose. Apps from left to right: NewsRack, Dictionary.com, Nike + iPod

Single Views Split views, limited views, etc. on the iPad

In-context Popovers Presents information that would normally be in a whole other view on a phone.

Modal Cards Another way to surface information without “leaving” the current view.

Beyond design

Review designs ★ Create an HTML website with hotspots and share the URL for review ★ Email images to be reviewed on a device

Get as close as you can to the real thing ★ Get set up with the dev environment ★ Test and run on the simulators ★ Even better, load on to a device ★ Even add assets and commit

Test interactions ★ Gestures and inputs ★ UI overload/fatigue ★ Scrolling and selecting ★ Navigation flow Image via scopeblog.stanford.edu

Physical prototypes ★ Don’t have the physical device? Fake it. ★ Made a wooden iPad to test before device was available Image via Jonathan Branam

Get user feedback ★ Form a user testing plan ★ Try to get “true” users ★ Conduct your own “guerilla” user testing
