Eye movement optimization in visual search
In the present study we investigated whether eye movements in visual search are optimized to reduce time on task. Subjects task was to find a target object in a large field of objects that differed based on shape, color, size and numeric label. The target specification was manipulated, directly influencing the average number of fixations it took subjects to find the target object. Although a mi...
متن کاملPersistence in eye movement during visual search.
As any cognitive task, visual search involves a number of underlying processes that cannot be directly observed and measured. In this way, the movement of the eyes certainly represents the most explicit and closest connection we can get to the inner mechanisms governing this cognitive activity. Here we show that the process of eye movement during visual search, consisting of sequences of fixati...
متن کاملSimple eye-movement feedback during visual search is not helpful
Searching for targets in the visual world, or visual search, is something we all do every day. We frequently make 'false-negative' errors, wherein we erroneously conclude a target was absent when one was, in fact, present. These sorts of errors can have tremendous costs, as when signs of cancers are missed in diagnostic radiology. Prior research has characterized the cause of many of these erro...
متن کاملSmooth eye-movement control with secondary visual feedback.
A signal derived from continuous measurement of eye position is displayed on a visual frame of reference, thereby closing a secondary visual feedback (2VFB) loop. The distance between a target and the displayed gaze point provides the subject with an extra, artificial position error. Experiments show that subjects can use the 2VFB to generate smooth eye movements, even in the absence of any smo...
