This chapter presents a research that enables the user to join a networked
virtual environment with a wearable computer. Different from the notebook
computer, the wearable computer is the computer system that allows the user
to operate it while moving. Consequently, the legacy keyboard and mouse are
not feasible input devices for the wearable computer to interact with the net-
worked virtual environment. To navigate the virtual world other positioning
devices (such as the GPS receiver is often used as the outdoor positioning
device) are required for the wearable computer user. However, the external
positioning device will cause temporal and spatial synchronization issues
between the wearable computing system and the conventional networked
virtual reality (VR) system. This paper investigates these issues and presents
solutions to them. The tips to implement such a system are also given. The
study shows linking up the wearable computing system and network virtual
environment as the augmented reality environment. The system supporting
this environment is called a multiplayer mobile augmented reality (MiMAR)
system. Finally, an ongoing 3-D virtual campus project is given at the end to
demonstrate the result of this research.
