在傳統的室內設計教學上，初學者在學習過程中常遇到的主要問題，是無法掌握縮小比例的
2D 草圖或模型與真實空間尺度之間的關係。這是因為他們缺乏直接面對 1:1 空間尺度的經驗和
知識，無法通過繪製縮小比例的圖來體驗和感知設計所呈現的空間感。傳統教學為解決這問題，
往往要求學生花費時間製作大尺寸的模型或圖來表達設計的空間感。而這種設計方法需要經過漫
長的反復嘗試，才能通過 2D 圖和模型來培養對空間尺度的感知能力。對此，本研究實作一套互

In traditional interior design teaching, the problem often encountered by beginners in learning is that
they do not know the real spatial scale relationship represented by the scaled down 2D sketch surface
or model. The reason is that they lack the experience and knowledge to directly face the 1:1 spatial
scale, and cannot experience and perceive the spatial feeling presented by the drawn design through
drawing the space reduction drawing. In order to solve this problem, traditional teaching tends to
require students to spend a lot of time making large-scale models or drawings to express the sense of
space of the design, and such a design operation method must go through a long period of training and
trial and error. Only gradually can the perception training of spatial scale be obtained through 2D
drawings and models. Therefore, this research implemented an interactive design system. This system
can be imported into VR application in the preliminary sketch design stage to assist in teaching. This
system uses the game engine to design APP, which can directly convert 2D drawings into 3D and enter
the VR environment experience and modify the furnishings and materials of the internal space. It can
also generate QR code, converted into 3D through interactive table recognition. In this study, through
the T-test analysis of the experimental questionnaire, the system has obtained consistent recognition of
the learning effect of the design assistance, especially for novices than experienced hands. This result is
in line with the expected purpose of the system implementation, helping design novice students to
shorten the learning time and effectively construct the perception of spatial scale.
