Researchers have released what they describe as the first publicly accessible emotion recognition dataset based on millimetre\u2011wave (mmWave) radar.<\/p>\n

The advantages are that this offers a contact\u2011free and privacy\u2011preserving alternative to traditional biometric sensors, the study\u2019s authors note. Biometric Update has an explainer on emotion recognition and its relation to biometrics.<\/p>\n

The dataset captures emotional responses from fifteen participants using three simultaneous signals: mmWave radar readings, photoplethysmography (PPG) pulse data and galvanic skin response (GSR).<\/p>\n

Participants also provided subjective ratings using the Self\u2011Assessment Manikin (SAM), a standard tool for measuring emotional valence, arousal and dominance.<\/p>\n

Unlike conventional emotion recognition datasets, which rely on wearable devices or video and audio recordings, the mmWave approach collects physiological information without touching the body or capturing identifiable imagery.<\/p>\n

The radar tracks subtle chest\u2011wall movements caused by breathing and heartbeat, allowing researchers to extract vital\u2011sign patterns without raising the privacy concerns associated with cameras or microphones.<\/p>\n

The team used validated film clips to induce emotional states and then analyzed the resulting signals to confirm both the effectiveness of the stimuli and the quality of the biometric data. They say the dataset opens new avenues for research, including cross\u2011subject emotion recognition, multimodal fusion techniques and comparisons between radar\u2011based and traditional physiological signals.<\/p>\n

It has to be said here that emotion recognition systems are considered highly dubious, if not outright unscientific, due to the difficulty of objectively assessing emotions. Emotion recognition technology has also been criticized for violating fundamental rights. This is especially the case in the European Union where the EU AI Act prohibits the development, deployment and placement of…<\/p>\n
