Asynchronous Displays for multi-UV Search Tasks

摘要: Synchronous video has long been the preferred mode for controlling remote robots with other modes such as asynchronous control only used when unavoidable in case of interplanetary robotics. We identify two basic problems multiple using synchronous displays: operator overload and information fusion. displays from can easily overwhelm an who must search targets. If targets are plentiful, will likely miss that enter leave unattended views while dealing others were noticed. The related fusion problem arises because robots' fields view may overlap forcing to reconcile different perspectives form awareness environment by "piecing them together". have conducted a series experiments investigating suitability multi-UV search. Our first involved static panoramas which operators selected locations at halted panned their camera capture record what could be seen location. A subsequent experiment investigated hypothesis relative performance panoramic display would improve number was increased causing greater problems. In Image Queue system we automated path planning also selection imagery presentation choosing greedy non-overlapping views. fourth set SUAVE display, variant picture-in-picture technique UAVs. addressed led similar well improved on measures. this paper review our experiences designing testing discuss challenges use including tracking dynamic © 2012 American Institute Aeronautics Astronautics, Inc.
