ORCLSim: A System Architecture for Studying Bicyclist and Pedestrian Physiological Behavior through Immersive Virtual Environments

Figure 5

Bicyclist’s HR change point analysis over time with other physiological responses. (a) Video snapshot of HR change point event 1. The bicyclist is approaching the intersection. (b) Visualizations of different physiological data. I: HR (blue) and HR BCP probability (red); II: horizontal head movement direction (black) and horizontal gaze direction (green); III: stationary gaze entropy (SGE) (cyan) and SGE BCP probability (red); IV: gaze transition entropy (GTE) (yellow) and GTE BCP probability (red). (c) Video snapshot of HR change point event 2. The bicyclist looked left behind to check if cars are approaching from behind.
