Abstract
A system with a see-through method is proposed, that provides explanations of electorical device’s(CD player) operation. In a situation that we are explained how to operate an electorical device, we would like to operate devices actually along with the explanation. See-through method is one of the powerful method for this purpose. This method augments the world by adding some Computer Graphics to the user’s view. So we can get more information from the view of augmented world rather than real world. To generate the CG correctly, the registration system is required, which tracks the user’s viewpoints, the object location and so on, and decides the coordinates of CG. For this purpose, our system uses only the video image from video camera. It makes the system simple and easy to use. The system is constructed based on two ideas, 1)acquisition of operator network that means operation sequence by planning method, 2)generation of surface expression(text, graphics and so on) from operator network through intermediary expression - Describe Action (DA). Operator network contains some operator which means operation of device, and some state description which means state of device. These are expressed on the explanation with text and the view of augmented world according to user preference and environment. The network transrate to DAs, and each DA generates surface expression.
