Dr. Ed Bachelder is a Principal Research Engineer at Systems Technology Inc., where he has been conducting research on human-vehicle interaction since 2001. His thesis was entitled Perception-Based Synthetic Cueing for Night Vision Device Hover Operation, and his post doctoral work at MIT’s Software Engineering Research Lab investigated operator mode confusion, developing graphical ways of identifying it and designing guidelines for preventing it. Dr. Bachelder has formal training in human-vehicle control modeling, dynamics and control, human-automation interaction, and machine vision. Prior to his entrance into the Ph.D. program at MIT, Dr. Bachelder was a Naval Aviator and was a Helicopter Aircraft Commander for the SH-60B Seahawk.

Dr. Bachelder is the inventor and patent holder of Fused Reality, a novel technique employing real-time blue-screen processing to merge virtual and physical environments for advanced simulation. He is also the inventor of the Optimized Autorotation Trainer, a pilot training system that computes and displays optimal control advisories for executing autorotation.  He was the Project and Concept Engineer of the CV22 Cabin Part Task Trainer Fused Reality Visual System, a Phase III USAF SBIR that employs Fused Reality for training the cabin crew of the CV22 Osprey aircraft. He is the Principal Investigator for “Frequency Domain Actuator Health Monitoring,” that employs wavelets to identify frequency response characteristics of servo-actuator systems (JSF).

Additionally, he is Principal Investigator of “Fused Reality for Enhance Flight Test Methods,” where Fused Reality is used for in-flight testing and training. As Principal Investigator for “Optimal Autorotation Tactile Cueing,” he employed nonlinear optimization and Fused Reality for active control cueing during autorotation. Dr. Bachelder was the Principal Engineer for “Flutter Suppression System Test Techniques,” for which he developed the novel Wavelet Eigensystem Realization Algorithm (WERA), simplifying and shortening flutter flight testing. He was Chief Conceptualist for “Intelligent Displays for Time-Critical Maneuvering of Multi-Axis Vehicles,” that employed real-time optimization to compute control advisories during autorotation.
