FlightAR: AR Flight Assistance Interface with Multiple Video Streams and Object Detection Aimed at Immersive Drone Control

The swift advancement of unmanned aerial vehicle (UAV) technologies necessitates new standards for developing human-drone interaction (HDI) interfaces. Most interfaces for HDI, especially first-person view (FPV) goggles, limit the operator's ability to obtain information from the environment. This paper presents a novel interface, FlightAR, that integrates augmented reality (AR) overlays of UAV first-person view (FPV) and bottom camera feeds with head-mounted display (HMD) to enhance the pilot's situational awareness. Using FlightAR, the system provides pilots not only with a video stream from several UAV cameras simultaneously, but also the ability to observe their surroundings in real time. User evaluation with NASA-TLX and UEQ surveys showed low physical demand $(\mu=1.8,SD=0.8)$ and good performance $(\mu=3.4,\ SD=0.8)$, proving better user assessments in comparison with baseline FPV goggles. Participants also rated the system highly for stimulation $(\mu=2.35,\ SD=0.9)$, novelty $(\mu=2.1,\ SD=0.9)$ and attractiveness $(\mu=1.97,\ SD=\ 1)$, indicating positive user experiences. These results demonstrate the potential of the system to improve UAV piloting experience through enhanced situational awareness and intuitive control.
