Developing Psychophysiologically Interactive Computer Systems

The framework was implemented in Java and C++ programming languages and it was used to construct two systems. The first system was a remote heart rate monitoring system. The second system was constructed for performing an empirical study involving both facial electromyographic and wireless electrocardiographic measurements. The first system was tested by four subjects who performed scenarios of voluntarily induced heart rate changes. Measurements from twenty-seven participants were collected with the second system. The results showed that the framework supported the construction of these systems and their accurate and reliable operation. The results also suggested that the framework supports extending these prototypes into robust real-world systems
