Tokyo Tech: Decoding Emotions Through Skin Conductance

Researchers at Tokyo Metropolitan University are pioneering the use of long-term skin conductance to distinguish emotions. This approach could elevate consumer electronics by enabling devices to offer services based on emotional states, moving beyond traditional facial data reliance.

In a groundbreaking study at Tokyo Metropolitan University, researchers have harnessed long-term skin conductance measurements to separate and understand human emotions. This innovative approach involves monitoring volunteers as they watch diverse video scenarios, from horror thrills to heartwarming family moments, while measuring skin conductance to decode their emotional responses.

Professor Shogo Okamoto leads the team exploring the potential of skin's electrical properties as a gateway to emotions. When individuals experience different emotional stimuli, their skin's conductance shifts, offering clues within mere seconds. This promising method might transform how consumer electronics interact with users, reducing the dependency on facial expression data.

The study revealed that fear induced the longest response, potentially due to evolutionary traits enhancing danger perception. Conversely, emotions linked to family bonding, a mix of joy and sorrow, emerged more gradually. Statistical analyses show that different emotional states can be differentiated through this technique, bringing us closer to emotionally intelligent devices.
