Teleoperation systems are increasingly used in remote inspection and maintenance, especially in safety-critical settings. This paper presents findings from a lab study examining user interaction with a teleoperation for airport safety inspection. The study investigates five visual interface configurations: First Person View (FPV), Third Person View (TPV), Augmented FPV, FPV+TPV, and Augmented FPV+TPV. Eighteen participants completed inspection tasks under each condition and rated interface helpfulness, workload (NASA-TLX), and simulator sickness. The result was confirmed by bootstrapping with 1000 iterations. Results showed that all view configurations were rated more helpful than TPV alone, with FPV-based combinations improving depth perception and spatial understanding. NASA-TLX revealed cognitive effort, while SSQ scores decreased post-task, particularly in oculomotor symptoms, suggesting adaptation. These findings support continued research into optimising visual interfaces for teleoperation in safety-critical settings
