Since Bob is not on his contact list, he selects “Add New Contact”. He is then taken to the screen that shows the various settings he can use to control the amount and type of his location information that Bob can view.
He can create settings according to what he wishes to share (in detail or in aggregate) with Bob. He then clicks the button called “Save Contact”. He can also cancel the form and start it again, if he wants to.
The breadcrumb trail helps the user navigate back to home screen of the app or home screen of the social contacts.
| Pros: As in the other screens, the information scent is strong because the user is able to identify and keep track of which part of the application she is in.
- Providing the map option makes it easy to learn and adapt since it is externally consistent with apps like Google Maps and gives the ability to directly manipulate. Cons: The screen does - The map provides good affordances and users can do direct manipulation on it. Cons: - The screen does not indicate which options are compulsory and which may be skipped. - The word "search for existing contact" is misleading because it has both the functionality of "search for existing and new contact." - The "Add new contact" is inconsistent with other social apps. It should come along with the contact instead of being as a static button. Also, the search bar location is inconsistent with other social apps. - The interface does not speak users' language. Too many jargons are used in the permission setting. Pros: Since all the features are clearly labeled, user can set the sharing options very quickly - Lack of immediate feedback. Users are unable to know what data they will share with the settings. An example here would be helpful. | Cons: - The list of options may seem tedious for many users.
- If the user wants to share the same type of location with multiple users, she will have to enter the same details all over again. Aggregation of location types may be helpful. Or, the interface should provide default/ recommended settings. | Pros: Cons: - Possible to make mistakes and over-/under share information. Confirmation dialogs may be helpful.
| Pros: Controls are clearly visible.
Cons:
- The search results might cover the "Add new contact" button.
- Duplicate search hints, that is, "Searching for existing contacts" and the "search" button. |
