This study examined the utility of eye-tracking as a control method during tele-operation in a simulated task environment. Operators used a simulator to tele-operate a search robot using three different control methods: fully manual, hybrid, and eye-only. Using Endsely’s (1995a) three level SA model and a natural interface (e.g., eye-tracking) as a more user-centered approach to tele-operation, the study measured objective, electroencephalogram, and subjective (NASA-TLX) measures to reflect both workload and situation awareness during tele-operation. The results showed a significant reduction in mental workload, as reflected by EEG measures. However a significant effect was found where the operators’ perceived mental …
