Abstract

THIS PROJECT WILL EVALUATE A NEW TYPE OF ALERTING SYSTEM DISPLAY: THE LIKELIHOOD ALARM DISPLAY (LAD). THE LAD FORMS AN OPTIMAL INTERFACE BETWEEN AN INTELLIGENT OR "EXPERT" COMPUTER MONITORING SUBSYSTEMS AND A HUMAN PILOT. IN A LAD DISPLAY, THE ALERTING SIGNAL PROVIDED TO THE HUMAN OPERATOR CONTAINS INFORMATION ABOUT THE COMPUTED LIKELIHOOD OF THE PROBLEM AS DETERMINED BY THE INTELLIGENT AUTOMATED SUBSYSTEM. THIS ENCODED LIKELIHOOD INFORMATION ENABLES MOREACCURATE PROBLEM DIAGNOSIS AND IMPROVED ALLOCATION OF PERATOR ATTENTION. THE LAD SHOULD RESULT IN IMPROVED SYSTEMPERFORMANCE AND REDUCED OPERATOR ERROR, ESPECIALLY UNDER HIGH LEVELS OF PILOT WORKLOAD. SYSTEM PERFORMANCE WITH LADSWILL BE EVALUATED FOR SEVERAL DIFFERENT TYPES OF TONAL AND SPEECH DISPLAY CODES.
