The human-machine interface (HMI) is a crucial yet often overlooked aspect in the design of Unmanned Aircraft Systems (UASs). A properly designed HMI enhances situational awareness and reduces the workload of the ground pilot, thereby contributing to improving the overall mission performance. Typically, a Human Factors Engineering (HFE) program provides a methodological process to support good design. The program comprises three iterative stages: requirements analysis and capture, design and evaluation. A number of approaches can be adopted in the HFE program but given the wide range of applications and missions that are being undertaken by different types of UAS, it is advantageous to adopt a functional approach towards HMI design, where the HMI is designed around specific functions to be performed by either the human user or the system. The typical UAS functions include mission planning, sensor operation, data analysis and sense-and-avoid (SAA), and can also extend to multi-platform coordination and collaborative decision-making. The human factors considerations and the associated HMI elements supporting these functionalities are discussed.
