| Summary: | 碩士 === 國立交通大學 === 建築研究所 === 95 === In the initial process of architectural design, model building is a pivot part of transferring concepts into visual bodies. Since the progress by CAD/CAM, initial phase modeling has evolved into digital models from traditional visual ones. Virtual models have become a new generation medium for architects during early design phase.
Digital modeling software has many distinct characters, such as duplication, modification, and material simulation. However, virtual models lack the tough in reality and the ability to express the feeling as a whole (Chang, 2005). In the past, many designers often faced difficulties on new medium operation. As a result, the presented designs sometimes did not match the original ideas. Basically, this kind of situation is due to designers’ unfamiliarity toward the user interface or the complicated process of operations. Toward these issues, some researchers made comparisons and researches between virtual models and traditional ones (Lin, 1999). To bring more senses of reality, digital and force-feedback gloves, such as VRAM, are applied to get the tough of virtual models (Regenbrecht et al. 1993; Wu, 2003). By using the “Designing Tangible User Interface”, the design process can be easily simplified. On the other hand, it also greatly helps designers operate the computer medium toward CAD.
Digitizing Stacked cube models is a simple method to help designers understand and analyze the space constructions and system frameworks (R. Aish, 1984). Besides, several relative researches have showed that interfaces such as Machine-Readable Models fit intuition quite well (J. H. Frazer, 1982). Recently, certain researches even developed into a further step. By using solid geometry models connected with computer, the virtual models react simultaneously while designers make digitized units moved (T. Murakami et al 1994; Matthew G. Gorbet 1998; J.Lee 2003;M. Eng et al 2004). However, this kind of operation mode lacks reality feedbacks from virtual systems. Some other digital model researches adopted a different kind of mode. By using electric-connected units, models of these units could link up with computers and be identified (D. Anderson et al 2000; E. Sharlin et al 2003). Nevertheless, this kind of process is not real time reacting no matter connected or not. During the unit-contracture process, the user cannot interact with the 3D model in real time. Moreover, since units are connected with the single phase connector, the connected phase is also limited somehow.Due to the limitation mentioned above, a new method is developed to solve these issues. By using a real time interaction implement, solid geometry models could control the virtual ones on the screen. In the meantime, virtual model could also give feedbacks simultaneously for interaction.
