Unobtrusive, wearable sensor array to collect actigraphy, ship motion, vibration, noise and temperature

This project will achieve an unobtrusive, wearable sensor array to collect environmental, physiological, and subjective measures associated with physical and cognitive fatigue. The proposed innovation, called the Warfighter Fatigue Data Acquisition System (WFDAS), will be an unobtrusive, modular sensor array to capture, synchronize, and download data related to: (1) actigraphy; (2) ship motion; (3) vibration levels; (4) noise levels; (5) ambient temperature; (6) light levels; and (7) subjective measures related to fatigue. Data will automatically download via open source wireless communication protocols (e.g., Bluetooth) to a networked laptop or smart phone where it can be exported for analysis or integrated with secondary applications (e.g., HSI"experiment in a box"toolkit). This tool will streamline operational data acquisition and reduce the burden for study participants. The software may also be configured to enable study participants to"self-administer"performance measures for use when experimenters are not able to be present (e.g., live fire testing). This project is directly responsive to the stated ONR goal to enable development and validation of performance shaping algorithms to predict the impact of environmental stressors including temperature, vibration, motion, noise, light and fatigue on warfighter readiness.
