   Permission setting page of Joe
                  for Bob

To add a new social contact,
Joe starts from his home
screen and clicks on "My
friends" button. He finds Bob
by typing his name in the
search bar (which is located
at the upper right corner.)
Joe then sets the permissions
for Bob. For example, in this
scenario,
1. Adjust the time by manipulating
    the clock-like interface.
2. Choose the places that are
     available for Bob by clicking 
     on the map. 
  (a)  Click on a new place to 
        create a new one. At the 
        same time, you can edit
        the place's radius and name,
        such as STATA or Boston.
   (b) Clicking on an existing 
         place can either delete it
         or edit it.
3. Hide/show aggregated information
    by clicking on the chart and the 
    Hide/show button.

Pros: 
1. The clock widget makes 
very easy to select the time. 
It is also consistent with other 
time widget. 
2. The map provides 
direct manipulation 
which allows user to  
choose the locations 
3. When Joe chooses a location 
on the map. It provides  
immediate feedback 

Pros: 
1. 
Cons: 
1. It might be cumbersome 
for users to set the  
permissions of each 
social contact one by one. 
Aggregation* *should be 
used. (ex. group permission 
settings.) Efficiency problem 
can also be mitigated by 
providing* {}default{} *
permission settings
   

The clock and map are salient 
to Joe.

  View Rei's offer by clicking on Rei 

The mail box animation pops up
when Joe sees the mail box when
there are offers available
to
himJoe. Upon clicking on the mail
box, Joe sees the list of offers.

To view Rei's offer, he clicks
on Rei's picture and sees the
location information that Rei 
wants from him in exchange
for the 10% discount.

In this scenario, Joe realizes the
information he will be exposed 
to Rei by his own example.
LocaShare mines for Joe's
past locations and visualizes
the information he is about to
share. Joe can choose to 
"Accept" the offer or "Cancel" it.

Pros:
1. Mail box animation is 
a good metaphor for 
receiving a notification.
Joe can easily understand
that there is something 
available to him.
2. Joe can easily learn the

information he will provide 
to the Rei by his historical 
location information. Learn
by example my own example
is an effective way to teach
user what will happen if I
accept the offer.

Cons:
1. It the list of offers is long,
scrolling down the long list
might be cumbersome. 
Would be better to aggregate
the offers by grouping them
into various categories.
2.
