DARLENE aims at development of AR-based smart glasses solutions for LEAs, with the aim to facilitate elevated situational awareness and more efficient decision-making during high-stress situations. The tools will aid LEAs identify illegal goods and activities by showcasing through the glasses a hyper-virtual representation of their surrounding environment, and alarming field operatives to imminent dangers when responding to high-risk situations, such as active shooting incidents. The fundamental components of DARLENE will thus consist of a wearable micro-computer module, capable of delivering performance and power efficiency needed for demanding visual computing applications, and a head-mounted display (HMD) unit embedded with tracking and sensing hardware, capable of running virtual 3D rendering applications in real time. This basic system will further be enriched with wireless, mobile hotspot transceivers, which will enable the CPU module compartment to act as a 5G access point. In this way, the HMD hardware and the AI (micro)-processing module can be linked through infrastructure-based short-range wireless technology, while simul-taneously linking to 5G digital cellular networks, accommodating secure high performance networking with a ML cloud, setup to accommodate intensive AI pipelines, such as Semantic and Instance Segmentation models, multi-person 2D and 3D pose estimation and anomaly detection mechanisms. In this way, DARLENE will orchestrate a high performant network architecture for new services with high demand in terms of extremely low latency and extremely high bandwidth. Extensive training and demonstration activities are planned throughout the lifetime of DARLENE, along with work on security and ethics by design approaches.
