Breathing is the most basic requirement for having good health. However, unhealthy breathing like overbreathing and hyperventilation will happened easily without any awareness. We propose an experimental breathing movement exercise system - Virtual Blowgun System (VBS), which offers a game well-designed for breathing exercise, for people of different physical strength, without space and safety limitations.

Using VBS as an example, 2 major themes will be provided to the visitors:

1. Method of building up a virtual training field using sensor technologies.

2.The application of view-dependent virtual reality.
