Biofeedback

Biofeedback is the process of gaining greater awareness of certain physiological functions. That can be done by using special devices and programs providing information about the activity of said functions, with the goal of being able to manipulate them at will.

Heart activity, skin conductivity, relaxation of the organism and more can be measured and displayed to the user. Some measuring devices feature a small display to show the data, others need to be paired with a phone or a computer.
