Trade-offs between Spatial and Temporal Resolution in Driving Unmanned Ground Vehicles:

Remote vision for steering unmanned vehicles is generally facilitated by on-board cameras. Due to limited bandwidth data links, a trade-off exists between spatial and temporal image resolution. This paper describes an experiment where objective performance of driving instructors was measured on a standardized task-battery in a fixed base driving simulator. The results showed that the optimum choice of spatial and temporal resolution is task specific. The lack of interaction between both the factors pleads for some provision for the operator to modify these parameters when switching between tasks.
