Basic Queries

After building essential queries to be performed, I have now designed the final objects to be implemented on the interface. For ease of build, I decided to use basic cubes. I believe users will find easier to build cubes than more complex shapes.

Data providers and object types
Data providers and object types

All these query elements are tied to Europeana’s Data Model thus allowing users to indicate the particular set of metadata that they want to find. Compared to my previous report, I have now removed the type of object from the queries. The User Centred Design study showed that not many people were particularly focused on the particular type until they got some results, thus making it a secondary tool. Nevertheless, I have still provided a display window of the amount of results retrieved per object type and provider.

When the query is entered, the list autoscrolls showing the user the whole list of providers. When a new query is entered, the list is updated and presents the new list to the user.

Users can choose the amount of results that they want to select. I have provided a pre-designed set of choices. These are: 12, 24, 48 and 96 results. Users choose these variables by rotating the pyfo. If the pyfo is removed, the last chosen option stays active.

The what, where and who pyfos will still have the option to add the OR or NOT boolean option. This is performed by rotation the main pyfo +or- 45º as indicated in the design.

Testing The Table

I have also finished building a small version of the prototype table. At this stage I am just finalising final technical details to make the markers more stable. They are still flickering to some degree. This might affect the interaction when testing the interface.

I designed a search and delete fiducials on a single pyfo (cube) object that will be used to enter or delete the elements on the screen.

Here is a video of the current state of the interface:
