【Objective】Traditional garden landscape construction requires a series of processes such as hand-drawn plan drawings, computer-aided modeling, scene rendering, etc., which display the problems of cumbersome process, high learning cost, and lack of intuitiveness. Based on virtual reality (VR) gesture interaction technology, this system proposes a novel virtual garden landscape layout system, aiming to improve the user experience and efficiency of garden landscape design.【Method】Firstly, a virtual wetland landscape scene was designed based on remote sensing satellite maps, and secondly, the Oculus Quest 2 device was used to collect hand information for recognizing multiple gesture patterns, and combined with the $P point cloud recognizer to design dynamic gesture classification algorithms to match the user’s gesture trajectories which realized the accurate recognition of five trajectories of garden plants: solitary planting, clump planting, row planting, piece planting and free layout. In addition, this system also designed gesture interaction system suitable for virtual scenes to facilitate the use of users.【Result】The system designed in this research adopted the unity platform and used C# scripting language for programming implementation, and finally realized the function of using gesture interaction to select plants and construct a garden landscape in a virtual scene. Through comparative experiments, the layout time required for this system was slightly higher than that of keyboard and mouse operations in the solitary planting mode, and lower than those of the keyboard and mouse operation in the row planting, clump planting, piece planting and free arrangement modes.【Conclusion】The gesture set generated by this research design system is intuitive, easy to execute and memorize, and can well accomplish the task of landscape layout. The system can make a certain contribution to improving the interaction and user experience of landscape layout.
