Hypotheses

Different Views:

1.    Users will use the two views in combination with each other to complete certain tasks. Regarding workflow and order of use during a session, users will start with the bullseye view and the go to the grid view. 

2.    Mapping tasks to views: users will use the Bullseye view for browsing gain a sense of the overview of the collectionÑand the Grid view for searching focus on a narrow parameter.

3.    Time spent using each view during the time it takes to complete a task will be approximately equal.

Ways to Navigate Time:

4.    Users will use the calendar the most to complete tasks, due to familiar icon recognition; users will use the drop down menus less.

5.    Users will use the features unique to the viewsÑGrid view + Prev / Next, Bullseye + Hyperlinked DatesÑonce they learn their functionality; times these functions are used, measured in number of clicks throughout a task, will increase. ***Note: we may choose to demo this functionality or decide to point it out to users should they noticeably miss it during the completion of a prescribed task.

Location and Friends Filters:

6.    Users will use both filters throughout the course of their session to complete their tasks.

7.    The number of times a Location filter is used, measured in number of times selected, will be greater than the number of times a Friends filter is used.

Photo Bin Buttons:

8.    Regarding Save Bin as Album, users will comprehend its function and click on the button successfully to complete a designated task.

9.    Users will make use of the Photobin buttons more often than resorting to these buttons on Album view or Single Photo view popup pages.

10.  When we have an opportunity to measure the use of both of these methods, the time it takes to use the Photobin buttons instead of the popup page buttons will be faster.
