For AR applications, we have developed a cyber threat alert system that leverages machine learning to detect potential security threats, tracking different digital sources of information to identify suspicious patterns indicative of an attack. Shortly after a threat is detected, users receive a visual warning alongside an audio message along the lines of “Your comfort or safety may be compromised. Take off your headset.” The voice volume gradually intensifies to capture user attention, with the alert persisting until they exit the app or remove the headset. This design reflects our dedication to combining advanced AI-driven threat detection with user-centred safety, making AR experiences both immersive and secure.
