Omnidirectional Traveling Instruction for Behavior Navigation.

With advances in wearable computing, wearable virtual reality and wearable robotics have become popular areas of research. This work focuses on task execution where traveling motion of a worker is required and the traveling instructions are provided to the worker by an instructor. The goal of this research is to develop the behavior navigation system that can provide work and traveling instructions through showing the instructions visually and intuitively. The worker is a person who executes a task at a work site according to visually presented instruction by the instructor. A graphical human model of the instructor which moves in the same manner as the instructor is presented to the worker to provide the work instruction. A traveling instruction is defined by the relative position and orientation based on the current position and orientation of the worker, graphically. The omnidirectional traveling instruction is realized by this relative traveling instruction. The effectiveness of the developed system has been verified by a number of experiments.
