The uulmMAC Database—A Multimodal Affective Corpus for Affective Computing in Human-Computer Interaction

Abstract

In this paper, we present a multimodal dataset for affective computing research acquired in a human-computer interaction (HCI) setting. An experimental mobile and interactive scenario was designed and implemented based on a gamified generic paradigm for the induction of dialog-based HCI relevant emotional and cognitive load states. It consists of six experimental sequences, inducing Interest, Overload, Normal, Easy, Underload, and Frustration. Each sequence is followed by subjective feedbacks to validate the induction, a respiration baseline to level off the physiological reactions, and a summary of results. Further, prior to the experiment, three questionnaires related to emotion regulation (ERQ), emotional control (TEIQue-SF), and personality traits (TIPI) were collected from each subject to evaluate the stability of the induction paradigm. Based on this HCI scenario, the University of Ulm Multimodal Affective Corpus (uulmMAC), consisting of two homogenous samples of 60 participants and 100 recording sessions was generated. We recorded 16 sensor modalities including 4 × video, 3 × audio, and 7 × biophysiological, depth, and pose streams. Further, additional labels and annotations were also collected. After recording, all data were post-processed and checked for technical and signal quality, resulting in the final uulmMAC dataset of 57 subjects and 95 recording sessions. The evaluation of the reported subjective feedbacks shows significant differences between the sequences, well consistent with the induced states, and the analysis of the questionnaires shows stable results. In summary, our uulmMAC database is a valuable contribution for the field of affective computing and multimodal data analysis: Acquired in a mobile interactive scenario close to real HCI, it consists of a large number of subjects and allows transtemporal investigations. Validated via subjective feedbacks and checked for quality issues, it can be used for affective computing and machine learning applications.

Cross-Subject Multimodal Emotion Recognition Based on Hybrid Fusion

“…The study in [19] proposes a fusion model based on verbal and nonverbal information to increase the emotion recognition capability of children companion robots. The study in [20] created a multimodal emotion database that includes the visual, audio, physiological, depth and pose data of 60 participants. Researchers in [21] collected participants' facial expressions, heart rate, pupil diameter and EEG data by showing them specific visual stimuli.…”

Emotion and Stress Recognition Related Sensors and Machine Learning Technologies

“…Building around a human-computer interaction (HCI) setting, [ 20 ] addressed the challenging issue of induction of dialog-based HCI relevant emotional and cognitive load states by presenting a multimodal dataset for affective computing research. The dataset used an experimental mobile and interactive scenario design that was implemented based on a gamified generic paradigm.…”

A Workflow for Affective Computing and Stress Recognition from Biosignals

“…The biosignal data used for developing the present workflow were acquired with the bioamplifier system g.MOBIlab+ from g.tec. The data are part of our previously acquired uulmMAC dataset-A Multimodal Affective Corpus for Affective Computing in Human-Computer Interaction-that is freely available for academic use and research applications [12].…”
