Adaptive Gaze Control in Natural Environments

Adaptive gaze control in natural environments.

The sequential acquisition of visual information from scenes is a fundamental component of natural visually guided behavior. However, little is known about the control mechanisms responsible for the eye movement sequences that are executed in the service of such behavior. Theoretical attempts to explain gaze patterns have almost exclusively concerned two-dimensional displays that do not accurat...

Memory and prediction in natural gaze control.

In addition to stimulus properties and task factors, memory is an important determinant of the allocation of attention and gaze in the natural world. One way that the role of memory is revealed is by predictive eye movements. Both smooth pursuit and saccadic eye movements demonstrate predictive effects based on previous experience. We have previously shown that unskilled subjects make highly ac...

Speech and Gaze Control for Desktop Environments

This chapter illustrates a multimodal system based on the integration of speechand gazebased inputs for interaction with a real desktop environment. In this system, multimodal interactions aim at overcoming the instrinsic limit of each input channel taken alone. The chapter introduces the main eye tracking and speech recognition technologies, and describes a multimodal system that integrates th...

Trained Eyes: Experience Promotes Adaptive Gaze Control in Dynamic and Uncertain Visual Environments

Current eye-tracking research suggests that our eyes make anticipatory movements to a location that is relevant for a forthcoming task. Moreover, there is evidence to suggest that with more practice anticipatory gaze control can improve. However, these findings are largely limited to situations where participants are actively engaged in a task. We ask: does experience modulate anticipative gaze...
