User-Centered Design for Mobile

Phase 1 – Rough Design/Scribbling (I)


Phase 1 – Rough Design/Scribbling (II)


> Scribbling on paper helpful for first iterations

> Very fast iterations to narrow down options

> Together with customer

> Together with implementation partner

Phase 1 – Rough Design/Scribbling (III)

> Together with implementation partner

> Good to agree on a basic concept

> E.g. application with tabbed navigation vs. application with dashboard

screen


> Axure RP 5.5 HTML prototype

> Viewport tag properly set to

> Fullscreen (without Browser Controls)

> Zoom locked

Phase 2 - Prototyping

Scroll down.

Use two fingers.> Zoom locked

> iOS dashboard bookmark to the

prototype

> Prototype limitations on iPhone

> 2 finger scrolling

> With new axure versions

not an issue anymore

Use two fingers.

And now up again.


Phase 2 - Prototyping


> 8 iPhone users (from expert to novice)

> Pretest interviews

> 10 tasks / scenarios

> Posttest interviews

Phase 3 - Usability-Testing (I)

> Posttest interviews

> Push Notifications were sent during

usability test through

> They did not see the Tab Bar for quite a

long time.

> Version 1:

> Top of screen as suggested by Apple Human

Interface Guidelines

Segmented Controls (=Tab-bar 2nd Level)

The Back Button Issue (II)

> Navigation back hierarchically works perfeclty fine

> As soon as the navigation is not hierarchical some users miss

a back button

> Gestures represent a very natural and intuitive way of interacting with

a system.

The issue with gestures (III)

a system.

> The downside:

> Only some gestures are intuitive, others have to be learned.

> Gestures are hidden.

> Users don‘t know them and mostly only find out accidentially.

> Only users with a certain proficiency recognize gestures which they

discovered accidentially.


The issue with gestures (IV)

> Swipe gesture discloses delete

button

> No participant knew this gesture> No participant knew this gesture

> Eventhough the gesture is available

in Apple email, messages and in

most apps with list views


The issue with gestures (V)

> Scroll up gesture discloses search

field to search a list

> Only 1 participant knew this gesture> Only 1 participant knew this gesture

The issue with gestures (VI)

the Favourites.

> No participant knew any shake> No participant knew any shake

gestures.

> Shake gestures should be used very

carefully because often annoying.

after first app startup

> 50% had almost an «allergic» reaction

to the push notifications

> During the post interview, push

notifications were rated as the most

negative part of the app!


> „Prefered supplier“-functionality

was kind of hard to understand.

> In the prototype:

> A Notification with User Education

User Education on Launch (I)

> A Notification with User Education

about the prefered supplier

functionality was shown after first start

up of the app.


> The notification was ignored in two

ways:

> Half of the participant just clicked it

away without reading for a second.

User Education on Launch (II)

away without reading for a second.

> The other half read it but did not

understand the message.


> User Education must be visual in order to work.

> Still then it is not sure wheter users remember the message.
