Biosensing technologies have advanced to a level where measurements of our physiology have become easily accessible, and new areas of application are being explored, including interpersonal communication via biosignals. To date, it is largely unknown what the communication characteristics of biosignal sharing are and how they influence experiences of biosignal-mediated interactions. By conceptualizing biosignal sharing as a new communication medium, we try to benefit from earlier theories and models that help describe and understand the communication properties that are inherently part of biosignal sharing, but have not previously been examined in this way. In this paper, we review the published literature on biosignal sharing and analyze the current state of the art using two complementary methods of analysis. First, we extend an existing framework of relevant communication dimensions and apply this to examine the characteristics of biosignal sharing systems. Second, we perform a thematic analysis on user experiences related to biosignal sharing available from literature. Then, we combine these findings and link the communication characteristics to the experiences of biosignal sharing. We discuss our findings, elucidating the way in which biosignal sharing affects the interpersonal communication process. Based on these insights, we provide several considerations for future research and design.
