Within five years, a new wave of smart hearing aids will be able to recognize stress, both current and anticipatory.
These intelligent devices will do this by collecting and combining several kinds of physiological data and then using deep-learning tools to tune the analysis to individuals, getting better and better at spotting and predicting rising stress levels.
The data they use will most likely include pulse rate, gathered using optical or electrical sensors, given that a rising heart rate and shifts in heart rate variability are basic indicators of stress.
