Use Case

As a media annotation tool, CARMA provides researches with the ability to collect continuous affective ratings of audio and video files. Possibilities include emotional stimuli, movies, music, commercials, political debates, lectures in classrooms, or even audio and video of the raters themselves.

Raters can be instructed to report on their own subjective experiences while viewing the multimedia file, what they were experiencing during the original task (if re-viewing audio or video of themselves), or what they imagine specific others in the audio and video files are experiencing.

Previous research has tended to focus on broad affective dimensions such as valence, arousal, and power. However, due to its customizable rating scale, CARMA can be adapted to nearly any project for which continuous ratings are desired. Specific emotional and cognitive states can be used in place of affective dimensions, allowing raters to report on experiences of anxiety, frustration, engagement, agreement, confusion, confidence, etc. CARMA can even be used to annotate non-affective information, such as the quality of teaching in the video of a lecture.

In the social sciences, the affective measurements collected with CARMA are likely to be used as the dependent variables of studies, allowing researchers to compare mean ratings across conditions or predict ratings given other factors. However, in affective computing and human-computer interaction, these measurements may also be used as training data for automated systems attempting to detect and analyze affective states from audio and video. Collecting responses from a variety of raters is critical for such a task, and an easy-to-use program like CARMA can greatly facilitate this data collection.
