The overall objective of this SBIR effort is to develop and verify an improved mathematical model of human gravito-inertial spatial orientation (SO) that estimates perceptions resulting from the integration of orientation/motion cues provided by visual, auditory, vestibular, and somatosensory senses, especially those cues existing in the aerospace environment. An advanced SO modeling system that includes an improved human gravito-inertial orientation mathematical model, can potentially reduce the number of aviation mishaps by predicting SD in-flight, and also be used to improve determination of causal factors in mishaps when SD is implicated. This project will develop a mathematical model that is compatible with various sensor inputs and will be capable of producing short cartoon animations showing a subjects actual versus felt (predicted) orientation and motion in a wide array of situations, especially those known to be disorienting to pilots. We propose a scientific and engineering development pathway that will also focus on experimental validation of the SO modeling system within a representative aviation environment. Success in this project will result in reduced mishap rates for US Army Aviation.
