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,本研究實作一套互動設計系統輔助學習,在初步的草圖設計階段便能導入VR應用在輔助教學,此系統利用遊戲引擎設計APP,可將2D繪圖直接轉換成3D並可進入VR環境體驗及修改內部空間的陳設與材質,另可產生QRcode,透過互動桌辨識轉換成3D。研究透過新手與熟手的實驗問卷分析,系統在設計輔助的學習成效上獲得一致的認同,尤其是新手認同度更高於熟手。這結果符合本系統實作的預期目的,輔助設計新手學生縮短學習時間及有效地協助空間尺度的感知。
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.
