EMMA is a collection of videos, recorded in the lab of the Interactive Intelligence Group of Delft University of Technology. We employed young Dutch actors to portray certain daily moods, occurring without interaction, such as sadness, anxiety and amusement. To make sure the actors were “into the mood”, we induced to them the desired moods with music, inspired them with scenarios (receiving a phone call, looking for something they lost, etc.), and let them free to improvise according to their felt mood and the situation. We recorded with two cameras, one focused on the face and one capturing face and body, and with Microsoft Kinect, located at a distance of approximately 2 metres away from the actors. All sensors remained at fixed positions, to resemble a typical smart ambience equipped with sensors. The actors could move around the setting, including sitting on the chair/couch, walking and standing. Due to the actors’ movements, the actor’s face is not properly captured in a lot of frames. We used the Kinect, to extract postural features, such as the joints and the rotational speed of the joints. We extracted the joints for each video offline in two modes: seated (10 joints) and standing (20 joints), each mode optimized for a different situation. Due to the suboptimal distance of Kinect from the actors, the skeleton joints are not detected in all frames of the videos. The joints are transcribed in separate text files, which can be downloaded under the title “Kinect joints”.
