e evaluated for contingencies that dynamically occur. Although very few performance benefitswere found for contours in this experiment, perhaps they would provide benefits in a systemwhose state is slowly changing or where the tasks are different.Other steps in this type of research of visualization techniques for power systems data areto explore the use of 3-D displays and motion. These visualization techniques were mentionedpreviously but not examined in this experiment. Many additional human factors issues arisewhen implementing these types of visualization techniques. They need to be empirically testedas to what their effectiveness and limitations may be.ACKNOWLEDGMENTSThis material is based upon work supported by the Power Systems Engineering ResearchCenter (PSERC).
