Abstract

The modern aviation industry is consistently embracing technological advancements to improve safety, efficiency, and training practices. Three user experience studies were conducted to examine the usability aspects of two digital components within aviation: the Federal Aviation Administration website and virtual reality head-mounted displays for aviation training.

The Federal Aviation Administration website serves as a central hub for aviation-related information, resources, and regulations for all domestic civil or military air operations within U.S. airspace. Usability is essential to ensure easy access to valuable data for aviation professionals, enthusiasts, and the public. Results from the experiences of ten pilots executing five tasks on the website found multiple usability errors and functionality issues that impeded their ability to complete tasks efficiently. The top five usability errors are presented with recommendations to address these issues. In parallel, virtual reality head-mounted displays are revolutionizing aviation training methodologies by providing cost-effective, immersive, and realistic experiences. Integrating technology allows trainees to practice in controlled environments, promoting skill acquisition, decision-making, and situational awareness. Two mixed-methods user experience studies explored the usability challenges and opportunities associated with virtual reality head-mounted displays in aviation training, beginning with their initial training session using the virtual reality head-mounted displays and continuing as they progressed through flight lessons in preparation for their solo flight. Usability Theory metrics such as usability, usefulness, ease of use, and satisfaction were investigated through multiple elements of virtual reality. These include engagement, visual fidelity, motion sickness mitigation, fidelity to real-world scenarios, and their impact on usability. Furthermore, Expectation Disconfirmation Theory constructs of user expectations (usability, ease of use, and satisfaction) as applied to the use of the VR HMD are also examined over time.

Keywords: usability, user experience, user expectations, aviation, virtual reality, online services, head-mounted displays
