Here, he can view various categories of products on a wheel. This visual representation helps him view various categories in a quick glance. Tiny numbers enclosed in circles indicate the number of offers by merchants/stores belonging to that category. Since Joe is at a ski resort and wants to buy some gear, he selects the wedge titled “Sporting Goods” . He and is then taken to the next screen that shows him the list of stores selling sporting goods and having offers. Here, Rei happens to be the store offering the two discounts in this category. Since the two offers require different location information (either in type or amount), the actual location value is not displayed here. <ac:structured-macro ac:name="unmigrated-wiki-markup" ac:schema-version="1" ac:macro-id="50ecc68e-9d07-4b42-9c0f-5c855d18d8ab"><ac:plain-text-body><![CDATA[[Note: you can view the sketch in the “Home ]]></ac:plain-text-body></ac:structured-macro> screen” section to see an example of the location information displayed below the store names]. The distance from his current location to Rei is also displayed (0.2 mi). Once he clicks on the region, he is taken to the next screen where he can see the two offers. Here we see that Rei is offering a 10% off in exchange for raw GPS coordinates. By default this would mean GPS coordinates in that state.

In both cases, Joe can
He can then click on the company providing the offers and see the details of the offers. To help Joe understand the exact information he would be sharing, LocaShare displays his current information as an example.
Joe can choose to accept or delete the offer by pressing the “Accept” or “Delete” buttons respectively. If he returns to the previous screen, these offers do not disappear from the screen and will be shown to him the next time he views the “Home Screen” for commercial contacts. Suppose that Joe decides to take Rei up on the first offer. He would now see the following screen that summarizes the information that Rei will receive and gives Joe to add Rei to a category (in case he wants it to be displayed in another category, or create a new category for this merchant/store). He can then Once he accepts an offer, he would see a summary of the information he is about to share with Rei on the screen. He can choose to create a category in which to save Rei as a contact. He finishes the process by pressing the “Save Contact” button or cancel the offer by clicking “Cancel”. If he clicks on “Cancel”, he will be taken back to the “Home Screen” for commercial contacts.
