Abstract

Human observers are able to allocate visual attention to multiple locations in a dynamic environment simultaneously. However, this ability depends on an individuals’ capacity to monitor the tracked objects' number, size, speed, and distance between objects. Moving objects in the real-world require that we independently allocate attentional resources to them. Recent studies have demonstrated that observers can focus attention on one location and ignore other locations; tracking performance improves when moving objects are rendered on a range of depth planes, and observers cannot track a moving object that abruptly changes depth in a 3D environment. We investigated whether an object’s abrupt or gradual changes improved attentive tracking under stereoscopic viewing in two experiments. These experiments indicated a similar pattern regardless of the depth-changing characteristics of the objects. Results demonstrated that abrupt- or gradual-changes of moving objects under stereoscopic viewing do not increase a tracking task's difficulty.
