Design and Implementation of a Software Tool for Human Factors Accident Investigation and Classification (PCTACT)
Abstract
A software tool was designed and Implemented that leads accident investigators through the steps of a Systematic Error and Risk Analysts (SERA), a classification scheme based on Perceptual Control Theory arid developed at DRDC Toronto The software presents an investigator with a series of questions about an accident and generates conclusions about the nature of the failure and its probable pre-conditions. A graphical depiction of the decision tree allows users to navigate easily among the steps of the analysis. At the end of the process, the software produces a report detailing failures arid pre-conditions, and providing equivalent terminology from the AGA 135 HF ACS classification scheme. A help system was developed that makes context-sensitive help available to the user at various stages of the process In preliminary work to lay a foundation for intelligent finding, users' activities are tracked by the software m a way that can be used in the future to provide intelligent and adaptive help. To Illustrate the potential use of the tracking mechanism, the software was designed to mom for user actions and offer help whenever there is a long delay without input.
