Capturing Heart Rate for Physiological Computing

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.

Summary: Russel (2003) – Core Affect and the Psychological Construction of Emotion

This is my summary of: Russell, J. A. (2003). Core affect and the psychological construction of emotion. Psychological review, 110(1), 145. In it Russel proposes a framework to talk about emotion at the psychological level, and aims at avoiding folk psychological concepts in his approach. Continue reading

Prototype 1: Autonomic Feedback Glove

During the last couple of days I have been working on a prototype to test a concept of my master thesis at Leiden University’s Media Technology program: Wearable devices that provide subtle autonomic feedback to their users. In this case we are talking about a  glove that can measure its wearers heartbeat and vibrates along in the rhythm. Continue reading
