This is my summary of: Valins, S., 1966. Cognitive effects of false heart-rate feedback. Journal of personality and social psychology, 4(4), pp.400–8. In it Valins describes the context, procedure and results of a psychological experiment designed to investigate the effects of false autonomic feedback on subjects experience of emotional content.

This is my summary of: Derks, D., Fischer, A.H. & Bos, A.E.R., 2008. The role of emotion in computer-mediated communication: A review. Computers in Human Behavior, 24(3), pp.766–785. The article provides a review of literature that deals with the expression of emotion in computer-mediated communication (CMC). The authors’ primary aim is to evaluate the widespread claim that CMC is less well suited for the communication of emotion than face-to-face (F2F) interaction, using the available scientific evidence. They reach the conclusion that this claim is not supported, and CMC and F2F possess similar capabilities for emotional interaction, with CMC in certain cases even enhancing the frequency and explicitness of emotional expressions.
In the following post I describe some methods and tools for capturing a persons heart rate for the usage in physiological computing/biosensing applications. It represents some of the research I conducted during for my master’s thesis, which deals with technologies providing autonomic feedback. The focus in this case was on simplicity of access in the context of mobile and wearable applications, not maximum preciseness of the data (such as might be a requirement for a laboratory environment or in a medical context). It describes approaches using two widespread methods: ECG/EKG-based and pulse oximetry-based measurements.
The development of the previous two prototypes — a glove and a wristband — provided valuable insights into the requirements for wearable technologies giving autonomic feedback, leading to the construction of this third version. It uses a Polar chest strap to detect a users pulse and translate it instantaneous into vibrations on a users wrist. It also is the first functional prototype providing possibilities for continuous, shared autonomic feedback between two people, albeit only across a short distance.
