Augmented Reality-Based Digital-Physical Space Registration and Projection for Cognitive Enhancement and Assessment

Driven by information technology, mod-ern warfare is more diverse and intelligent than traditional warfare, in which intelligent unmanned system plays an increasingly important role. To defend against distant threat of unmanned military arma-ments, it's essential to deploy radars, sonars, satellites, and other long-range detection equipment to build a multidimensional national defense monitoring system. Due to the unpredictable nature of battlefield, radar-based reconnaissance missions require operators to have extensive experience and maintain a high level of focus. However, prolonged radar operations may impose a heavy psychological burden on operators and even affect their mental functions. To address these challenges, this paper proposes a cognitive en-hancement and assessment system that projects virtual 3D battlefield scenarios onto the real world based on augmented reality and evaluates operators' mental state through eye-tracking technology.
