Experience & Design in the Mobile World

User Interface and Experience DesignNathan Freitas, [email protected]

When developing software for the web or a desktop computer, you only need to consider the mouse and the keyboard.

With a mobile device, you must take into account the entire world around you (and your users).

Possible User Input Sources for a Mobile Device

• Keyboard

• “Click” Tap via Touch (or Stylus)

• Wheel or Trackball

• GPS or Network Location

• Accelerometer Motion

• Orientation / Compass / Altitude

• Vibration

• Sound / Music

• Wireless Network Coverage

• Environment Lighting

• Multitouch and Gestures

• Device Security / Loss

Three Device Classes

Mobile devices can be categorized by their physical dimensions, network connectivity,

software capabilities and more

Low: WAP / SMS

(my SMS business card)

Medium: Java / J2ME / Symbian

High: Apple iPhone, Android, Windows Mobile

User Experience, Desires & Dreams

Think about the “60 second” use case...

and then think about the “60 minute” use case.

60 second = quick reference, lookup or messagedirections, scores, stocks, weather...

60 minute = long, in-depth interaction while relaxing, wasting time or on a train or planenetworked game, writing / reading / browsing, movies, podcasts, project / finance management

Casual

Serious

UtilityGame

Dice

RPG

Flashlight

12 Myths of Mobile User-Interface Design

• Users want power and aesthetics. Features are everything

• What we really need is a Swiss army knife

• 3G is here!

• Focus groups and other traditional market analysis tools are the best way to determine user needs

• If it works in New York, it will work anywhere

• The killer app will be games, --er, no, I mean, nightlife, or gps.... uh...

• Mobile devices will essentially be phones, organizers, or combinations, with maybe music/video added on

• The industry is converging on a UI standard

• Highly usable systems are just around the corner

• One underlying operating system will dominate

• Mobile devices will be free-or nearly free

• Advanced data-oriented services are just around the corner

Create Your User Stories

I want to be able to find all the open happy hours nearby so I

can save money

While I am shopping at a store, I want to be able to find out if I

can get it cheaper online

I want to be able to poll my friends for advice at any moment

I am walking to get fast food and I’d really like my lunch to

be ready when I get there

As I go for a run, I want to know how my pace is

compared to others my age.The camera should wait until

my hand is still and the shot is level before the picture is taken.

Think About Where & When

• At the office, during a meeting

• By a parent, during breakfast

• In the backseat of a taxi

• By a doctor in a hospital

• By a soldier at a base

• At a sales meeting, for a $$$ deal

• By a single parent, making dinner

• In the drivers seat of a semi-truck

• By a doctor in Rwanda

• By a soldier, under fire
