Abstract
In this paper, we discuss the development of wearable systems which we collectively term VizWear. Vision plays an important role in both people's and computers' understanding of contextual information, and the use of augmented reality(AR)techniques is a good way to show information intuitively. This is the basis of our research on wearable systems and services based on CV and AR techniques. Our wearable systems enable us to run different multiple tasks in real-time. In this paper, we introduce four component functions implemented on the wearable systems.
