  Biofeedback is commonly used to regulate one's state, for example to manage
stress. The underlying idea is that by perceiving a feedback about their
physiological activity, a user can act upon it. In this paper we describe
through two recent projects how biofeedback could be leveraged to share one's
state at distance. Such extension of biofeedback could answer to the need of
belonging, further widening the applications of the technology in terms of
well-being.
