Our results thus far indicate that with the displays we have used the oculomotor and cognitive systems function with remarkable efficiency. For example, by linking saccadic target selection to the same attentional filter that serves perception it becomes unnecessary for observers to make a separate decision about where to aim the eye. The line of sight will automatically go to the attended region after a go signal is issued to trigger the movement. Moreover, the limitations on the attentional demands of saccades, which we have observed, mean that considerable resources are available for selection of potential targets before the saccade is initiated. Finally, the finding of a highly precise spatial pooling process means that observers need only select a target object the precise endpoint of the saccade is determined automatically by lower level visuomotor processes that do not require deliberate or cognitive intervention. All of these principles may prove of value in the design of artificial visual systems that must aim sensors to selected targets in large visual scenes.
