通过设计训练模型，即实训沙盘的操作，强化学员对理论的理解和构建，最终提高问题解决能力。训练沙盘，包含6个主要交互设计环节，和所有的设计方法卡片，及其附属A3大小的方法详解。设计环节基础为一个立方体，立方体每个面可以吸附（或抽插）一个方法学习卡片；多个立方体可以相互联接与拆卸；最终多个立方体可以展现出一个完整的设计流程，也可以一个立方体展示完整设计流程。物理沙盘的样式及教学形态见下图。

交互设计方法体系贯穿设计任务的各个阶段，涵盖了从整体分析到适合不同阶段使用的具体的交互设计方法，最终使学员得以从流程上了解并掌握设计过程不同阶段中合适采用的设计方法。

围绕交互设计方法体系，方铭研发出“交互设计实训沙盘”和“交互设计数字沙盘”两个产品。其中，交互设计实训沙盘是应用在设计师探讨设计任务执行过程中需要选择的交互设计方法体系过程中的实训工具。

The interactive design method system is a complete method system of step-by-step process and hundred methods, which is extracted by Fangming R&D team, based on the project operation experience of enterprises in different industries for more than ten years and combined with the scientific research and teaching experience of universities. This method system can not only be used as the implementation steps and methodological guidance of interactive design projects for industry enterprises, but also the theoretical basis of talent training programs in Colleges and universities.

The interactive design method system runs through all stages of the design task and covers the specific interactive design methods suitable for different stages from the overall analysis. Finally, the trainees can understand and master the design methods suitable for different stages of the design process from the process.
