Research and development applications are used to study emerging mixed reality technologies with high-fidelity professional teams and on-site fieldwork. The extended study improves the CSI system by streamlining evidence collection in realism assessment, reducing evidence contamination, and enabling collaborative teamwork. We evaluated this exam on usability and satisfaction. 1) The System Usability Score (SUS) was above average at 69. The high score was due to show tag and symbol marker substitution usability metrics. 2) Quantitative and qualitative findings were confirmed by the clear correlation between perceived efficiency and observed time reductions in evidence collection. User feedback technology is great, and the collaborative aspects assist them in their work. This analysis is supported by empirical case studies and concludes with a forward-looking perspective on the future integration of MR with other FBI recommendation steps and evidence, advocating for a robust framework to guide its responsible and effective use in law enforcement and the justice system.EnergyBusiness, Management and AccountingComputer ScienceMedicineDecision SciencesConference PaperSCOPUS10.1109/TIMES-iCON67125.2025.114880872-s2.0-105040622820
