Coordinating System Responses Based on an Operator's Cognitive Response to a Relevant Stimulus and to the Position of the Stimulus in the Operator's Field of View
First Claim
1. A method of cueing a system response, comprising:
- monitoring neurophysiological responses of an operator subjected to stimuli;
processing the neurophysiological responses to determine if the operator had a significant cognitive response to a stimulus to generate a positive cue;
monitoring the operator'"'"'s eye movement to determine when the operator fixates on the stimulus;
determining the position of the stimulus in the operator'"'"'s field-of view (FOV);
outputting the positive cue and the position of the stimulus; and
triggering a system response to the positive cue and the position of the stimulus.

Abstract
Neurophysiological responses such as EEG signals of brainwave activity, dilation signals of pupillary response, dwell time signals of eye movement and imaging signals of vascular response are monitored as a correlate of the operator'"'"'s cognitive response. These responses are processed to determine if there is a significant cognitive response to a stimulus (visual or non-visual) to generate a positive cue. The operator'"'"'s eye movement is monitored to determine when the operator fixates on the stimulus and the position of the stimulus in the operator'"'"'s field-of view (FOV). The positive cue and position of the stimulus, and typically the time-stamp of the cue are output triggering a system response. The temporal sequence of cues and stimulus position may be processed to reinforce or reject the cue or refine the stimulus position.

20. A system comprising:
-
a head-mounted system for an operator, said system comprising; at least one sensor monitoring neurophysiological responses of an operator subjected to stimuli; a classifier processing the neurophysiological responses to determine if the operator had a significant cognitive response to a stimulus to generate a positive cue; an eye-tracking device monitoring the operator'"'"'s eye movement to determine when the operator fixates on a stimulus; means for determining the position of the stimulus in the operator'"'"'s field-of view (FOV); and a wireless data link transmitting the positive cue and the position of the stimulus; and a remote system receiving the cue and position and triggering a system response to the positive cue and the position of the stimulus. - View Dependent Claims (21, 22, 23, 24)
