ab: Summary: The present study was the first in line of a series of experiments
    investigating the possibilities of using voluntarily produced
    physiological signals in computer-assisted therapy. The current aim was
    to find out whether computer-guided voluntary facial activations have
    an effect on autonomous nervous system activity. Twenty-seven
    participants performed a series of voluntary facial muscle activations,
    while wireless electrocardiography and subjective experiences were
    recorded. Each task consisted of activating either the corrugator
    supercilii muscle (activated when frowning) or the zygomaticus major
    muscle (activated when smiling) at one of three activation intensities
    (i.e. low, medium, and high). Our results showed a voluntary facial
    activation control effect (FACE) on psychological (i.e. level of
    experience) and physiological activity. Different muscle activations
    produced both task-specific emotional experiences and significant
    changes in heart rate and heart rate variability. Low intensity
    activations of both muscles were the most effective, easy to perform,
    and pleasant. We conclude that the FACE can clearly open the route for
    regulating involuntary physiological processes.
