Investigating Cardiovascular Activation in Routine Driving Through Naturalistic Studies
My doctoral research focuses on the insidious physiological effects of apparently benign machine usage, such as daily drives. Currently, we report on a naturalistic study investigating the effects of routine driving on cardiovascular activation. We recruited 24 drivers, and using their own smartphones and smartwatches, we monitored for a week both their driving and non-driving activities. Monitoring included the continuous recording of a) heart rate throughout the day, b) hand motion during driving as a proxy of distractions, and c) contextualized driving data, complete with traffic and weather information. These time series variables were complemented with the drivers’ biographic and psychometric profiles. Analysis at the trip level suggests that anxiety predisposition and high speeds are associated with significant cardiovascular activation on drivers. These findings call for attention to the insidious effects of apparently benign drives. Accordingly, our research contributes to HCI discourses in Personal Health Informatics, naturalistic studies, and the design of Physio-Aware interfaces that can track such phenomena. As next steps, we plan to conclude the study’s data collection operation, which has a target n=60 participants. In that expanded dataset, we plan to apply Machine Learning (ML) and Deep Learning (DL) methods to draw individualized cardiovascular activation predictions at fine temporal resolutions. It is through such personalized predictions that we plan to operationalize awareness of these underappreciated physiological phenomena at scale.
