Students in these periods have design experience but still not very familiar with using drawings to express spatially ideas. We got experiment data about 4 participants. Experiment results will presented as table (page.15). Experiment

In this stage, we only provide 2D site information. 2)Participants are brought to site and operate SARDE. They will see the full scale 2D draft which is combined with site enviornment. 3)The experiment stop when the participants want to stop. 4)After the experiment, we discuss with participants immediately. 5)After the experiment we analysis and summarized the video tape to clear the most important design behavior.

This research establish an designer-design interactive model, We believe that more display technology is developed,more interactive design support system possibilities could be explored. 2. Combine 3D perspective with full scale elevation, and detect the position of designer’s eye with immediately perspective adjust feedback. 3. Projected surface with precise scale and changing scale quickly maybe helpful in urban design, when thinking in different scale levels. Discussion Ｅｎｄ
