Can AI develop a system that can detect and respond to a person's emotional state in real-time, using physiological signals such as heart rate and skin conductance ?

What if technology could read not just what you say or type, but how you feel—moment by moment—by tracking the subtle signals your body sends? Researchers have explored systems that detect emotional states from physiological cues like heart rate and skin conductance, but bridging detection to meaningful real-time responses remains an open challenge in affective computing.
Background
Current systems leverage wearable sensors and machine learning to analyze physiological signals for emotion detection. Wearable devices collect heart rate variability, skin conductance (electrodermal activity), and other metrics that correlate with stress, anxiety, or excitement. Machine learning models—often trained on labeled datasets from affective computing research—identify patterns associated with specific emotional states. For example, increased heart rate and elevated skin conductance may indicate stress or arousal, while slower heart rate and reduced conductance could reflect relaxation. Pioneering work by the MIT Affective Computing Group and commercial platforms like Affectiva’s Emotion AI (2022) has demonstrated real-time emotion recognition in contexts ranging from mental health monitoring to personalized recommendation engines. Despite these advances, the translation of detected emotional states into timely, contextually appropriate system responses remains an active research area. Challenges include balancing latency, ethical considerations, and the dynamic nature of emotional expression across individuals and cultures.

Can AI develop a system that can detect and respond to a person's emotional state in real-time, using physiological signals such as heart rate and skin conductance?
Narrow demos exist — but the panel was not unanimous.
The jury found the system capable of reading emotional currents like a barometer reads the sky but not yet skilled in interpreting the storm inside. While AI can track the tremors of a heart and the dance of sweat in real time, it still stumbles when asked to translate those signals into nuanced comfort or counsel rather than raw data, leading two jurors to pause just short of full endorsement. The ruling: "AI can feel the pulse, but not the heart.
But the data is real.
