Abstract: A system and method of hierarchical monitoring for subordinate assessment is described. Generally, the system receives remotely sensed data about a user's physiology and contextual state, and extracts features that are related to the workload currently being experienced by a single subordinate and/or group of subordinates. The system builds workload indices based on levels of these features. The system uses statistical process control techniques in conjunction with the workload indices to identify suboptimal user states. Information regarding a particular subordinate or the group of subordinates may be presented in a variety of different ways. As a result, a superior can easily determine the condition of the one or more subordinates and make task adjustments to influence workload levels.

Abstract: A method and system are provided that prioritize the output of an image triage that is based on rapid serial visual presentation. User responses and estimates of the effectiveness with which each image is likely to have been processed by a user are employed for post triage image prioritization of potential targets. Images associated with a user response, processed during optimal user states, are assigned the highest priority for post triage examination, as targets are likely. Images without a user response that are processed during optimal user states are assigned the lowest priority, as these are unlikely to contain targets. Images with a user response that are processed during suboptimal states are assigned a medium priority, as these are likely to contain a high number of false positives. Images without a user response, processed during suboptimal user states are flagged for reprocessing as these may contain targets that the user may not have detected.

Abstract: An augmented tutoring system is provided that includes a simulation device, at least one sensor and a controller. The simulation device is adapted to provide a simulation that has an objective to accomplish by a student, wherein to achieve the objective a plurality of tasks must be correctly completed. The at least one sensor is adapted to monitor a cognitive state of the student while engaged with the simulation. The controller is adapted to process cognitive state information from the at least one sensor and to process student progress information relating to the completion of each of the tasks. The controller is further adapted to provide feedback to the student based at least in part on the processed cognitive state information and the processed task completion information.

Abstract: A method and system provide for user sensitive pacing in an image triage that is based on rapid serial visual presentation. The physical or cognitive state of a user is monitored during the image triage, and images are shown to the user at a predetermined image presentation rate. The image presentation rate is adjusted during the image triage in response to the physical state or cognitive state of the user. For example, the image presentation rate can be decreased to match a decreased capacity of the user to process images, or the image presentation rate can be increased to match an increased capacity of the user to process images. In addition, the showing of the images can be paused in response to inattention of the user. Further, one or more of the images can be resequenced for examination by the user if such images are missed because of eye blinks.

Abstract: A method of providing perspective depth information on a computer screen. The method includes generating light and dark areas so that it appears to the observer a light source is illuminating the information from an imaginary point in space. The method further includes maintaining the appearance of the light source from the imaginary point in space when the information displayed on the computer screen is rotated in relation to the observer.

Abstract: A display screen for displaying multiple sets of information is provided. The display screen includes at least one region of a select color designated to convey a first set of information and a plurality of adjustable areas designated to convey a second set of information. The plurality of adjustable areas overlay at least a portion of the at least one region of select color of the first set of information. Moreover, each adjustable area is defined by an outline and a color encased in the outline.

Abstract: A communications system is provided that includes a communications scheduler adapted to receive messages from a plurality of message sources and sensors. The messages comprise human and generated messages. The sensors comprise situational, neurophysiological and physiological sensors. The cognitive state profile processing unit receives sensor data and produces a current cognitive state profile for the user.
