The Collect Window

The Collect window allows users to load and control multimedia files while recording ratings on a numerical axis. During recording, ratings can be adjusted by mouse and keyboard (by manipulating a slider) or by USB joystick.

To collect ratings, users must use the Open Multimedia File menu option and then left-click the Play button. This will trigger a three second countdown during which users can prepare for the annotation task; the position of the slider is not recorded during this period. Once the countdown is up, the multimedia file will begin playing and the slider position will be recorded.

During rating collection, users can pause CARMA in three ways: they can left-click the Pause button, press the spacebar on their computer keyboard, or left-click the close (i.e., "X") button on the top-right of the window. This will immediately halt the collection of ratings and pause the multimedia file. Users can then left-click the Play button to resume their ratings after another three-second countdown. If users paused CARMA using the third option (i.e., clicking the close button), they will be prompted to cancel their ratings. Selecting "yes" will clear the currently loaded video, allowing users to load a new video or close the Collect window. Selecting "no" will keep CARMA in its paused state, from which it can be resumed as usual.

After the multimedia file has fully played and all the ratings have been collected, users will be prompted to save their ratings to an annotation file. Annotations can be exported as Comma-Separated Values (.CSV). Comma-Separate Values files are fast to create and open, simple to read, and small in size. Annotation files contain nine header rows that provide information about the file itself as well as how CARMA was configured when it was collected. These files can be opened in Microsoft Excel or statistical analysis packages, such as SPSS and SAS, as well as any free text editor, such as Notepad++.
