This study explores the use of Augmented Reality (AR) to mitigate attentional tunneling and enhance task performance by redirecting attention effectively across multiple visual cues. A user experiment involving eighteen participants was conducted to evaluate the effectiveness of two types of AR cues-Minimap and Line-compared to a control condition with no AR assistance. Participants performed a series of tasks using a head-mounted display (HMD) while interacting with a touchscreen in a simulated environment. Results show that both AR cues significantly reduced missed alerts and decreased cognitive workload, with the Line cue proving slightly more effective in reducing response time to peripheral alerts. The findings suggest that AR-based interventions can improve attention management and task performance in complex systems by countering the effects of attentional tunneling. This study highlights the potential of AR technology to enhance operational safety and efficiency in high-stakes environments.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing → User studies; Mixed / augmented reality; Interaction designHuman centered computing → User studiesMixed / augmented realityInteraction design10.2312/egve.202413659 pages
