Newspapers are also highly mobile

But sort of hard to read this way...

Too bad this doesn’t fold up

mobile devices have created arevolutionary new medium

KVM (Keyboard, Video, Mouse)is a transitional interface

Somewhere between dials and knobs...

interaction

Mobile is more natural: touch & voice inputsCarried on the body, mobile extends us

We’ve become Cyborgs

mobile is disrupting the user experience:

design paradigms,constraints,metaphors

Design is creation for use

Design has intent

Expressing intent as simply as possible is good design

OPTIMIZE

OPTIMIZING MOBILE UX - FORM FACTOR

• Small viewport = limited screen real estate - Old nav paradigms not e�cient, use new lighter models - Shorten content for a�ordances and headings

• Make your affordances big (40x40px +10 px) • Hovers = fail• Popups stink• Reference the platform interface guidelines

OPTIMIZING MOBILE UX - PERFORMANCE

• Load times are just as important as ever• Minimize payload - including using the UX to break up requests• Perceived performance as an element of your user experience

OPTIMIZING MOBILE UX - CONTEXT OF USE

• Map your user scenario & touchpoint• Design for a 1-minute timebox• Divided attention, not sustained attention • Mobile usage is not about engagement - Usage tends to be destination-driven - The completion of a speci�c task - Responding to an alert or checking update

OPTIMIZING MOBILE UX - CONTENT

• Different labels work better on mobile• Always be succinct• Map or storyboard your content along a linear sequence
