The attribute of depth has been shown to provide saliency or conspicuity for items in a visual search task. Novel displays that present information in real physical depth offer potential benefits. Previous research has studied depth in visual search but depth was mostly realized without real physical separation of display elements. This study aimed to better understand the effects of real physical depth and eccentricity on visual search in a depth display. Through this understanding, we can appropriately utilize this new technology. An experiment was conducted to test four hypotheses regarding how depth, eccentricity, target feature, and screen location would …

The present study tested the hypothesis that three visual pathways (i.e. parvocellular, magnocellular, and koniocellular pathways) may influence the degree of dual-task interference using dual-task methodology. The magnocellular pathway consists of feature-coding mechanisms that are sensitive to transients and motion, and is thought to process information about the locations and movements of objects. The parvocellular pathway consists of feature-coding mechanisms that are sensitive to red-green and brightness information, while the koniocellular pathway consists of feature-coding mechanisms that are sensitive to blue-yellow chromatic information. Both the parvocellular and the koniocellular pathway are thought to process information useful for identifying objects. The …
