Motivation
The purpose of this research is to identify how to intuitively operate 6 DOF Input Devices for interactive data storage in 3D virtual environments.
It is under the condition that the role of the computer is to simulate the way people sense the real space, so
users may instinctively utilize this simple device to explore the possibility of data recurrence and reorganization, and
designers may receive timely inspiration in the process of architectural design.

Objective
This research studies the way people navigate 3D VES information system and the actual spatial experience.
I then develop a 6 DOF device for implementing basic navigational function with easy operation and compatibility with different interfaces.

Conclusion
During the implementation testing of 6DOF input device, the hardware itself tends to fix the posture and wear people out so they are not able to browse for extended period of time.
Spiral-type browsing offers a new visual experience that helps us rethink whether in the 3D browsing environment there can be operational modes other than simulating the way human beings walk to give users different experiences in the visualized information-browsing space.

Future Works
A 6DOF device will provide some empirical and real data for analysis of human navigation behaviours.
This can be explored along dynamic interactive spatial experience.
With the device, extended controls can be defined.
