A computing system was developed to produce a real-time cardiac-based measure of arousal based on changes in respiratory sinus arrhythmia to enable physiological-based closed-loop feedback.
A computer system today receives no data regarding the physiological state of the user, but there are many cases where these data could be useful. For example, as the user becomes bored or lethargic, the system could raise the workload or audiovisual feedback to stimulate arousal. As the user becomes tense or strained, the system could lighten the workload or simplify the feedback to lessen arousal. This type of physiological-based closed-loop feedback could be applied in a number of scenarios, such as training, stressful repetitive work (e.g., air traffic control), and military operations. In this article, the authors describe a computing system that produces a real-time cardiac-based measure of arousal. The measure is based on changes in respiratory sinus arrhythmia, an established measure of vagal activity. They describe the measure, the measure's potential and limits, the computing system, and the new directions for physiological monitoring research made possible by such a system.
Hoover et al. (Tue,) conducted a other in Arousal / Vagal activity. Real-time cardiac-based measure of arousal was evaluated. A computing system was developed to produce a real-time cardiac-based measure of arousal based on changes in respiratory sinus arrhythmia to enable physiological-based closed-loop feedback.
