What is Mobile UX ?
User’s perception of the usefulness, usability,
and desirability of a mobile application based
on the sum of all their direct and indirect
interactions with it.

Mobile is growing – fast!
International Data Corporation IDC predicts that by 2016 more than 1 billion
smartphones a year will be shipped.

A couple “Laws” relevant for mobile
Hick’s Law: The more things there are to choose from,
the more time it takes to make a decision
– Limit the choices you offer at once
Fitts's Law: The time required to select something is a
function of the distance to the target and the size of
– Make the tap targets big enough

What makes a usable mobile interface?
Meet users' needs quickly
– ‘immediate’ information – directions, phone
numbers, addresses or instant entertainment.
– Shortcuts through LBS, links to call, email
Don't repeat the navigation on every page
– Page real estate is particularly precious on a mobile
– Where as normal WebPages display the navigation
options on each and every page, this is not always a
viable option on a mobile device.
– The Content often IS the navigation
10 Mobile UX Overview | 30/09/2013
What makes a useable mobile interface?
Clearly distinguish selected items
– Selected items should stand out from everything else –
by changing font, colour, size, borders etc.
Make user input as simple as possible
– Text input is limited on mobile devices – avoid it where
– Offer list picks, date barrels
– Big targets to pick from
Take advantage of phone features
– Bar code scanner

maintain; One strategy to
SEO-friendly - A single URL
makes it easier for search
engines to find your content

page load times

Adaptive design - What Is It?
16 Mobile UX Overview | 30/09/2013
Responsive designs - Good idea?
Q: Are the tasks performed cross-platform the same?
17 Mobile UX Overview | 30/09/2013
Responsive patterns - Basic
Only a single transformation.
Remaining adaptation is very gradual
and is merely a narrowing of the initial
Less resource intensive but still elegant.

Focus on the most important things first
“If you design mobile first, you create

Ask your users (FG’s, CrowdSourcing)
I know what
What are the primary tasks?
24 Mobile UX Overview | 30/09/2013
Consider the opportunity of each design element
Display only relevant content.
Keep it short and simple.
Use the available phone features.
– LBS, camera etc.
Make the design interruptible.
– Save state often.
4. Design with mobile considerations
26 Mobile UX Overview | 30/09/2013
Some Final Thoughts
The mobile web is different than the static PC
Understand the various contexts of use
Consider mobile first
Native app, web app or hybrid?
Define constraints – e.g. screen size
Is a ‘Responsive’ Design suitable?
Do research with users and prototypes
Get something on device ASAP & research in context
