Software for Continuous Affect Rating and Media Annotation (c) Jeffrey M Girard, 2014-2023

CARMA is a media annotation program that collects continuous ratings while displaying audio and video files. It is designed to be highly user-friendly and easily customizable. CARMA enables researchers and study participants to provide moment-by-moment ratings of multimedia files using a computer mouse, keyboard, or joystick. The rating scale can be configured on a number of parameters including its labels and numerical range. Annotations can be displayed alongside the multimedia file and saved for easy import into statistical analysis software. CARMA provides a tool for researchers in affective computing, human-computer interaction, and the social sciences who need to capture the unfolding of subjective experience and observable behavior over time.



CARMA was first published by Jeffrey Girard in 2014 under the GNU General Public License version 3 (GPUv3). Users are free to use, distribute, and modify the program as outlined in the license. CARMA is meant to be a modernization of Gottman & Levenson’s affect rating dial. A journal publication describing CARMA and its use was published in 2014. However, note that the program and its functionality have changed a lot since that initial publication.
