 
Home screen The list of social contacts (friends)
The list of commercial contacts (deals) | When Joe logs into the
LocaShare app, he sees
the home screen, which
only has two buttons.
By clicking on the "My
friends" button, he sees
the list of his friends
(social contacts),
and by clicking on the
"My deals" button he
sees the list of his
deals (commercial
contacts).
Also, clicking on the
"LocaShare" button on
the upper left corner
leads Joe to the home
screen. | Pros:
1. The friends and
deals buttons are huge,
and this makes them
salient to users.
2. The icons for friends/
deals are presented by
pictures. Joe can easily
recognize his friends/deals.
Cons:
1. Search bar might be too
small to be noticed.(We
should test this in paper
prototyping.)
| Pros:
1. The user interface is
externally consistent
with other social applications.
2. The user interface is
internally consistent since
the ways to list friends and
deals are similar.
3. The UI conveys itself to the
Joe by using the texts Immediate
*feedback * feedback is also provided
when Joe clicks on the buttons. | Pros:
1. By providing the
search bar, Joe can
find his friends easily,
and this prevents Joe
from scrolling down
on the long list in order
to find a specific
person or deal.
| If Joe wants to see a deal
but mistakenly clicks on
the "My friends" button.
He can easily resolve
this problem by going
back to the main screen. |
