Changes in oxygenation in normal volunteers are associated with short-term SpHgb signal loss (<10 minutes), but no impact on the measured SpHgb.

Task saturation is observed in simulated CCATT missions. Nontechnical skills correlate with task saturation. Task saturation is associated with worsening physiologic derangements in simulated patients.

The Human-Machine Perceptual Cooperation (HMPC) paradigm combines a human operator's high level reasoning with machine perception to solve spatioperceptual intensive problems. HMPC defines two channels of interaction: the focus of attention (FOA) by which the user directs the attention of machine perception, and coni?ext. As the user moves the FOA across a display via a pointing device, a smart cursor operates proactively on the data, highlighting objects which satisfy the current context. The FOA permits foveal emphssis, enabling the user to vary motor precision with image clutter. HMPC provides for contexts at four levels of abstraction. This permits the efficiency of the system to degrade gracefully as data quality worsens. We describe a document analysis application to which HMPC is applied. 1 In this project, a human operator works with a machine to convert scanned raster maps into vector format.
