Android App Incorporating the PVT to Deliver Individualized Fatigue Risk Management in Commercial Trucking

The overarching objective of this project is to achieve an Android App that incorporates the Psychomotor Vigilance Task (PVT) to deliver Individualized Fatigue Risk Management in 24-7 occupations that involve fatigue stressors (e.g., extended duty hours, chronic sleep restriction, night work, and jet lag). This project has the following 3 specific aims: (1) Develop PVT feedback algorithm for use with truck driver populations; (2) Design smartphone fatigue management user interface with vigilance feedback and sleep entry; and (3) Develop prototype Android App with PVT and fatigue management interface. During this project we met all of the objectives. We completed an Android App with PVT and fatigue management interface. This app enables users to perform the PVT, set a wake-up alarm, input and track sleep history, and receive feedback from PVTs taken. The deliverables achieved in this project provide a critical element needed to complete the next stage of our research and development—the Android App with PVT and fatigue management interface to complete data acquisition on commercial truck drivers during long-haul trucking operations.
