- Unmanned aerial vehicle (UAV) are multifunctional, reprogrammable machines use to gather information from remote locations and then send back information to the controlling individual. Today, there are attempts to search for the ratio between operators and vehicles that will prove most efficient and effective. Presently, the ratio is around unity of 1:1, UAV:operator. However, design aspirations are for ratios that significantly exceed unity, as 4:1 or perhaps hundreds of UAVs to a single operator. The 1:1 ratio is more preferable, but the pressure to achieve an even greater personal ratio is destined for sensory input conflict, central decision-processing overload, and response confusion and interference.
