Introduction
Site environment becomes design supporting system
1) Intuitional manipulate 2D or 3D objects2) 1:1 visual feedback3) Real time visual feedback and are easily adjusted
depending on different situation4) Portable for any situation

4.1 Purpose of experiment
By asking participants to operate SARDE, we understand whether this system useful or not, and some advice from participations.
4.2 Participant
The participants are those who learn architecture design within two to three semesters. 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).

4.3 Steps of experiment
1) Participants are asked to use 2D drawing ,such as plan, elevation, and section, to make design decisions. 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.

(c) Participant pretended to touch the table
(d) Participant simulates how to writing on desk
(e) Participant choose blue color to represent glass
(f) Infill color.
(g) Readjust infill area
(h) Decide the location of poster

6.2 Significance and feedback
Our research propose a new vision to let designer seems to enter his imaginary, and let design behavior return to human scale behavior.

6.3 Limitation and Future studies
1. 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.
