 | Recall that Joe is looking for
Bob, who isn't there to meet him.
From the home screen, Joe clicks
on People and then finds Bob.
By staying in the "now" tab, he
can see Bob's exact location on
a map. | Pros:
- Design has external consistency
with other mobile apps
- Provides visual feedback by showing
the map.
- It speaks the language
of the
user since the labels are
easy to understand.
Cons:
- The map interface can
be confusing if Bob
gives a state-level permission.
Would the marker mean
that Bob is in that location?
| Pros:
- The current location is clearly
shown to the user. Easy to
view in a couple of glances.
Cons:
- The user has to browse through
the entire list of contacts to spot the friend.
Having a search feature will be more efficient,
since that is externally consistent with other
mobile applications.
| Neutral:
- Might press on
Alice when you want to view
Bob. This can be solved by
using the back button on the app.
Pros:
Cons:
| Pros:
- The map is large on the screen
and provides strong information
scent by showing only
the essential details.
Cons:
- Important information is
not directly visible. See the
learnability 'Cons' for an example.
