How iPadChanges

Everything

Obligatory photo:

“Make the screen five inches by eight inches, and you’ll rule the world.”

- Alan Kayhttp://bit.ly/dAXgsQ

News Flash:Computers are

still too complicated

Those who design & build computers are most likely to

forget this

The Gulf of Knowledge

HackersBloggers

Tech columnistsYou

Keep this in mind when evaluating new technology

What’s wrong with the status quo?

Files

“On Mac OS X, the /System/Library/ folder...

contains over 90,000 items, not one of which a typical user should ever need to see or touch.”

- John Gruberhttp://daringfireball.net/2009/12/the_tablet

My mom has ~100 files on her desktop

Mouse

Geeks still argue about 1-button vs.

2-button mice

The mouse is a bug, not a feature

Your StanfordC.S. Degree

To your family,this still means“tech support”

Not just a generation gap

Opportunity to fundamentally

rethink computing

DesigningGreat Apps

(My) Three Rules

1. It’s not an iPhone2. Don’t break the flow

3. Make it feel real

1. It’s not an iPhone

“It’s just abig iPod touch!”

- Someone on the Internet

Hardware? Maybe.Software? NO!

Don’t just recompileyour iPhone app

Apps that do this will not be well-received

2. Don’t break the flow

“One view onscreen”no longer the only way

Use split views

Don’t abuse it

Use popovers formodal content

Full-screen transitionscan be disorientingon a large display

3. Make it feel real

Direct manipulation

Tactile, physical interface design

Postage Classics ConvertBot

Realisticsound effects

Animations!

Not just eye candy

Help user to builda mental mapof your app

Some specific tips:

Read theHuman Interface

Guidelines

Work with agreat designer

4x the pixels=

4x the ugly

Performance isa BIG DEAL

Test on a real iPadfor performance

and usability
