61% of the world will be coming online for the first time soon using
(mostly) cheap mobile devices.
Many of these users will intially be mobile-only.
If you aren’tproviding users withsites optimized for
mobile use, it’s time to catch up.

PROTOTYPES
The primary purpose of a prototype is to get to better, more useful work.

“New rule: every desktop design has to go finger-friendly.”
--Josh Clark (@globalmoxie)

To build for the future, we need to makeour responsive designs more tablet-friendly.
Places primary navigation in easy range of fingers, on the sides or bottom.
Example: Google +
Adjust designs for height to accommodate the dual display nature of tablets.

u
Example: Apple iPhone
Adjust designs for height to accommodate the dual display nature of tablets.
Use bigger touch target areas to accommodate finger / thumb input.
Example: Good.is
MIT researchshowed the average
fingertip is8 to 10 mm.
~7 to 9 mmminimum
recommendedbased on
manufacturer.
Consider side-swipe navigation where appropriate.
Example: Yale School of Management
Anchor content to the side of the browser (not just to the side of the body).
Example: Quartz
Bonus round: use transitional interfaces (carefully) to augment the touch experience and add affordances.

Talk about speed, not style.
Designing for speed
Responsive design requires different layouts for different breakpoints.
webster.edu
Layout means more design and development time per breakpoint...
webster.edu
...and multiply the breakpoints times the browsers / devices you’re testing for.
Baseline browsers we test:• IE 8+• Firefox 18+• Chrome 24+
Devices for mobile / tablet testing:• iPad 3• iPhone 4s• HTC DNA• Kindle Fire 2• Nexus 7• Galaxy S II• Droid Razr• iPhone 5
Simpler design makes it easier to design across layouts, devices, and browsers.
Page weight has a linear, negative impact on conversions, page views, bounce
rate, and returning visitors.

Tests at Amazon showed that every 100 msincrease in load time decreased sales by 1%.

Speed touches nearly every measurable metric of a web project.
That means speed is everyone’s problem.
What can you do?
1. Learn how to check page weight in your browser.

2. Minimize the number of custom fonts and external widgets per page.
3. Include designers and developers who understand web performance
from the beginning.
GOOD + FAST EXAMPLES

USABILITY
“If you aren’t talking to your users and lettingthem have a say, you aren’t doing UX.”
--@TimothyWhalen
What is a minimum viable strategy forpostdesktop usability testing?
1. If you can, always user test your prototypes AND your alpha site.
2. Perform critical path testing for eachbreakpoint where layout changes.
mobile tablet desktop
3. Test users on different devices toconfirm input types work intuitively—
a minimum is mouse & trackpad vs. touch.
4. Always do usability tests specifically for the mobile breakpoint.
Two things that need to be impossible to miss at any mobile breakpoint:

5. Test people ontheir own devices.
Design for speed and simplicity.
