The SMART-BARN (scalable multimodal arena for real-time tracking behavior of animals in large numbers) achieves fast, robust acquisition of movement, behavior, communication, and interactions of animals in groups, within a large (14.7 meters by 6.6 meters by 3.8 meters), three-dimensional environment using multiple information channels. Behavior is measured from a wide range of taxa (insects, birds, mammals, etc.) and body size (from moths to humans) simultaneously. This system integrates multiple, concurrent measurement techniques including submillimeter precision and high-speed (300 hertz) motion capture, acoustic recording and localization, automated behavioral recognition (computer vision), and remote computer-controlled interactive units (e.g., automated feeders and animal-borne devices). The data streams are available in real time allowing highly controlled and behavior-dependent closed-loop experiments, while producing comprehensive datasets for offline analysis. The diverse capabilities of SMART-BARN are demonstrated through three challenging avian case studies, while highlighting its broad applicability to the fine-scale analysis of collective animal behavior across species.
SMART-BARN（用于实时跟踪大量动物行为的可扩展多模态竞技场）可在一个大型（14.7 米×6.6 米×3.8 米）三维环境中，使用多个信息通道，快速、稳健地获取动物群体的运动、行为、交流和相互作用。该系统可同时测量来自多个分类群（昆虫、鸟类、哺乳动物等）和不同体型（从飞蛾到人类）的行为。该系统集成了多种并发测量技术，包括亚毫米级精度和高速（300 赫兹）运动捕捉、声记录和定位、自动行为识别（计算机视觉）以及远程计算机控制的交互式单元（例如自动喂食器和动物携带设备）。数据流可实时获取，允许进行高度受控和行为依赖的闭环实验，同时生成全面的数据集供离线分析。通过三个具有挑战性的鸟类案例研究展示了 SMART-BARN 的多样化功能，同时强调了其在跨物种的集体动物行为的精细分析中的广泛适用性。
