SHAPING SYSTEMS TO THE SOLDIER


PERFORMANCE CHALLENGE


Michael Ploechl, right, of Osnabrueck University in Osnabrueck, Germany, demonstrates a brain-computer interface called RSVP-based Adaptive Virtual Environment with Neural-processing (RAVEN), with Jason Metcalfe of DCS Corp. observing Ploechl’s task performance as he uses the response pad to indicate categories of images (threat or non-threat) while moving through a simulated urban environment. This particular study looks at how to use psychophysiological factors (such as electrical activity from the brain, heart, muscles and skin), behavioral factors (eye and face movements, and task performance) and subjec- tive measures (questionnaires) to interpret and predict changes in emotional state during performance under changing levels of competitive stress and task difficulty.

Even more exciting are the design possibilities our

systems that adapt to their users and help them maximize performance no matter the conditions. For example, a system could infer the Soldier’s cogni- tive state—whether the Soldier in the fight is overwhelmed with visual or audi- tory stimuli, battlefield stress or injury. It might recognize whether the Soldier has forgotten how to use the system effectively. Te system could deter- mine if it could provide training on the battlefield that could help the Soldier

survive. If the user’s learning curve is too steep, the system could infer that the Soldier is misinterpreting data or incorrectly managing the system, and provide corrective measures.


CONCLUSION Te goal is to improve Soldiers’ effec- tiveness and protection, so that when their lives and the lives of friendly forces depend on their making the correct deci- sions, whether from a drop-down menu,
