Abstract
A system for estimating emotional valence continuously based on physiological measurements of respiration activity comprises a respiration sensor, a low-performance computing device configured to acquire the sensor data and estimate an emotional valence state of the wearer an emotional valence estimator, a high-performance computing device configured to provide feedback to the low-performance computing device in order to improve valence estimation and a display to show the estimated valence level. Related methods are also disclosed.

A system for estimating emotional valence continuously based on physiological measurements of respiration activity, comprising:
- a respiration sensor;
- a low-performance computing device configured to acquire the sensor data and estimate an emotional valence state of the wearer via an emotional valence estimator;
- a high-performance computing device configured to provide feedback to the low-performance computing device in order to improve valence estimation;
- and
- a display to show the estimated valence level.
A method for estimating emotional valence continuously based on physiological measurements of respiration activity, comprising:
- measuring a respiration signal via a respiration sensor;
- calculating a depth of breath, breathing cycle time, and respiration rate based on the respiration signal;
- generating a marked point process (MPP) using a k-means grouping algorithm on the calculated depth of breath, breathing cycle time, and respiration rate;
- estimating a valence level based on the MPP;
- and
- displaying the estimated valence level.
