The Department of Defense, specifically the Army, is seeking innovative solutions for the development of precision contact lens eye tracking sensors aimed at enhancing Extended Reality (XR) interactions, training optimization, and cognitive monitoring. The objective is to create a system that can operate effectively in rugged, mobile environments, overcoming the limitations of current camera-based eye tracking technologies that require stable conditions for accurate data collection. This initiative is critical for improving command and control capabilities in dynamic military scenarios, with applications extending to both manned and unmanned operations. The solicitation is currently closed, with the opportunity having been released on November 14, 2023, and the application due date set for January 3, 2024.
