San Diego, CA, July 28, 2005 -Sandra Marshall, CEO, EyeTracking, Inc., and James Weatherhead, President EyeTracking, Inc., each presented papers at the Augmented Cognition track of the International Conference on Human-Computer Interaction in Las Vegas.

Sandra Marshall’s presentation, entitled “Assessing Cognitive Engagement and Cognitive State from Eye Metrics”, describes a new approach for estimating cognitive state by using a set of psychophysiological metrics based on eye-tracking data. The metrics are derived from the raw data of pupil size and point-of-gaze information. Each metric requires only 1 second of data for computation, which means that the set can essentially be computed in real time. The set of metrics is described, and three examples of using the set of metrics to determine cognitive state are given. The first example contrasts focused attention with potential overload; the second example compares attention with boredom, and the third example differentiates between fatigue and moderate cognitive effort.

James Weatherhead’s presentation, entitled “From Disparate Sensors to a Unified Gauge: Bringing Them All Together”, addresses the issues dealing with the unification of multiple sensor channels into one or more gauges of cognitive state for the Augmented Cognition Program. This paper describes one method for solving the data integration problem using the Cognitive Workload Assessment Dashboard (CWAD). One of the CWAD’s most important functions is its ability to store all the sensor and simulator data in a meaningful way. A key element in making the data accessible is a common time stamp for all inputs and outputs. The CWAD contains a unique system for synchronizing the data, allowing not only selected extraction but also a fully synchronized playback of the session. This paper describes the CWAD implementation in one component of the AugCog Program.
