Overview of several databases described in the introduction section.

The databases included in this table share one or more features with our new database such as: focus on body motion, motion capture format, rich set of emotion categories (more than the six basic emotions), naturalness of the produced motion, large number of motion samples. These shared features are highlighted in bold. The table highlights the following properties: the major formats the data was recorded in (Audio, Motion capture, Video), the emotions expressed, the modalities recorded (Body, Face, Respiration, Speech), the mode of the emotions (Elicited vs. Naturalistic), the size of the database/dataset, the number of actors, the number of observers/raters, and the context in which the data collection took place. The highlighted initial letters in bold correspond to the code letters in the format, modalities and mode columns. The last row describes the new database for the easiness of comparison.
