| Summary, etc | Present day aircraft systems are becoming incredibly complicated with the advent of new technologies.<br/>As per International civil aviation organization’s safety report, failure of mechanical or any physical<br/>hardware has reduced over the years due to highly reliable systems. The main reasons of incidents or<br/>accidents are pilot related - either pilot error due to experiencing high workload, loss of situational<br/>awareness, delay in task execution, lack of crew coordination; to name a few. Further, the proposed<br/>next generation aircraft cockpit solutions focus more towards considering human autonomy. In<br/>general, they focus on concepts such as providing larger Multi-Function Displays (MFDs), integrated<br/>and interchangeable displays, Pilot Vehicle Interface (PVI) solutions such as touch based displays, 3-<br/>dimensional audio, gesture recognition, speech recognition, haptic flight controls, seamless cockpit<br/>displays and so on. Hence it is important that pilot’s capabilities and limitations are considered while<br/>designing these display interfaces. We cannot assume that pilots will capture all the available<br/>information at all times for decision making. In other words, human’s sensory modalities such as vision,<br/>auditory senses, verbal senses and sense of touch should be utilized optimally. Designers should<br/>consider the limitation that human errors are induced when the mental tasks demand more resources<br/>than operator’s capabilities. Hence, when these kinds of advanced concepts are being designed,<br/>designers should also parallelly develop technologies for validating these designs. Such evaluations<br/>should consider pilot to be in the loop. The scope of my research is to understand human factors in an<br/>aircraft cockpit and to identify methodologies to evaluate pilot aircraft interfaces. My dissertation<br/>initiates with identifying areas wherein eye gaze tracking can be used to evaluate cockpit interfaces. In<br/>the first user study, I set up a non-intrusive SmartEye based eye tracking system at CSIR-NAL’s flight<br/>training simulator and pilot in the loop simulations were conducted for predefined test scenarios. The<br/>study concentrates on specific applications of eye gaze tracking such as evaluating usefulness of display<br/>or symbology, monitoring pilot’s scan behavior, understanding pilot-display interactions and to<br/>estimate the variations of pilot’s cognitive load. Results from this study found correlation between the<br/>statistical inferences obtained from the ocular parameters with those obtained from the flight path<br/>deviations. Based on the understanding on the various applications of eye tracking, I develop a support<br/>system that can assist the designers or evaluators in real time. Real-time display of gaze fixation, scan<br/>path of gaze movement and scatterplot of the gaze location is provided as feedback on pilot’s attention<br/>allocation. |
