In the context of this project, physiological sensing refers to the use of sensor to capture signals related to underlying human physiological phenomena. A few examples of data captured as part of this project are heart rate, breathing rate, facial temperature, cerebral hemodynamic response and muscle activity.
Current technology advances allow for signals related to human physiology to be captured with less invasive sensors and often in more ecologically valid environments. This in turn offers opportunities for collecting these data while operators are performing various types of jobs in order to better understand how changes in operator states reflect in the data. The hope is that this will lead to guidelines on how to better design jobs.
