---|---|---|---|---|---|
View friends | * All users succeeded to get this information without any difficulty. Most of them were also able to use the drop-down menu, aggregate information, and the current location. | * One of the users were confused with | * Most of them didn't find the "My LocaShares with sb." button. | N/A | * We can solve the learnability problem by arranging the LocaShares in the drop-down |
Create a LocaShare | * one user commented that having a New Share button on the homepage is inappropriate -- you should add something only after viewing what you already have. | * No create button on My Shares page. | * typing in place names is very slow. Not clear how to fix this. | * Back buttons and confirmation provide effective safety. | * add example sentence to indication location, city, state as valid inputs. |
Edit a LocaShare | One user thought that inconsistency (sequential v non-sequential) with Create process was confusing, another user really liked it. | * It doesn’t make sense that you edit a share created for multiple people by entering through an edit menu associated with a single person. | * Inefficient to figure out what’s being shared with one person -- in order to see times of day and week, the shares must be opened one-by-one. | * There is no confirmation dialog for editing. | * Alternative interface might edit shares starting by location instead of by person. |
LocaShare overview | All the users looked at the home screen for a long time to | * Photo on home page does not | * Users mentioned that a lot | * This task did not involve | * Provide better information scent (with the profile photo on the home page). |
Reflection:
We learned a great deal from the iterative design process we carried out for this project -- both about the difficulty of predicting what a user will think when using an interface, and about the difficulty of determining the essential features of an interface in order to achieve a minimal, highly usable design.
