互动沙盘是一种基于可计算信息的沉浸式交互环境的三维虚拟仿真技术的沙盘模型。 采用以计算机技术为核心的现代高科技手段生成逼真的视、听一体化的特定范围的虚拟环境，用户借助必要的人际互动设备（触摸屏、自动感应器、激光笔等）、大屏幕显示设备（多屏投影显示、液晶屏、LED全彩屏等），以自然的方式与大屏幕上的三维模型/虚拟场境中的对象进行交互作用、相互影响，从而产生亲临等同真实环境的感受和体验。
Interactive sandbox is a sandbox model of 3D virtual simulation technology based on Immersive interactive environment with computable information. Using modern high-tech means with computer technology as the core to create a realistic virtual environment with a specific range of integration of viewing and listening, users can use necessary interpersonal interaction equipment (touch screen, automatic sensor, laser pen, etc.), large screen display equipment (multi screen projection display, LCD screen, LED full color screen, etc.) to naturally interact with the three-dimensional model / virtual field on the large screen The objects in the environment interact and influence each other, so as to produce the feeling and experience of the same real environment.
