This project aims to address the issue of fatigue on Navy personnel by remotely monitoring their gait pattern to measure levels of attentiveness. Fatigue diminishes cognitive and physical performance, hindering mission-related tasks. In our project, we propose an insole device integrated into normal footwear to detect changes in cognitive and physical performance using gait patterns. Drawing on studies highlighting the cognitive demands of gait, the group designed a gait monitoring device that analyzes the impact, mid, and active ground reaction forces as well as stride time to determine a sailor's levels of attentiveness. Priorities for this device include accuracy, reliability, cost, and ease of use. Alternative designs explored wearable devices similar to an ankle bracelet or an armband. Each design was evaluated against project objectives and constraints. Our final design involves a ZNX-01 insole sensor to track relevant gait data and an Arduino Nano ESP32 to evaluate the data. The group also began work to develop an algorithm to analyze a subject's gait data to determine their level of attentiveness. This step is still in progress. The algorithm will be uploaded to the Arduino and used to analyze subject data. Additionally, an integrated mobile app has been developed to accompany the device via Bluetooth. This device will be able to monitor a Navy sailor's gait data and provide feedback on their level of attentiveness. Through this project, we aimed to provide a non-invasive, cost-effective solution to enhance Navy personnel performance, and potentially benefit other industries and populations facing similar challenges.
