The document discusses navigating 3D information spaces using 6 degree of freedom (DOF) input devices. It aims to identify intuitive ways to operate such devices for interactive data storage. The researcher analyzes gestures for interacting with 3D spaces and implements a 6 DOF device based on these gestures. A demonstration of the device shows navigation of a 3D virtual environment built using the MUSE platform. The summary concludes that while hardware devices can tire users, alternative browsing modes beyond walking simulations could provide different 3D experiences.

CAADRIA2004 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.

CAADRIA2004 Research Question  These complex systems are for multi-functional operation. They are too intricate for simple navigation of 3D VES information system. Function 1 Function 2 Function 3 Function 4
CAADRIA2004 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.

CAADRIA2004 Navigation Demo
CAADRIA2004 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.
CAADRIA2004 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.
CAADRIA2004 The END
