There are varieties of methods for realizing the augmented reality. For example, there is a method to display augmented information and video information on a single display using augmented reality markers. However, this method needs the users to look at the display. In order to share same information among multiple persons, everyone should look at the displays that show the same image. Projection type augmented reality solves this problem. Projection type augmented reality is the method

Every person can share the experience at the environment. However, the method needs many preparation works and enormous energy for freely projecting images. It can work on only limited conditions, such as indoors or at night. Our research solves these problems. We propose a method that works in a head-worn type equipment using the method of projection type augmented reality. It recognizes an object from the camera images. It projects a mark that carries a little information onto a recognized object. There is an error of the position where the mark projected when the equipment moves. We decrease this error using an angular velocity sensor. We propose the method, the implementation and the experiments for evaluating the performance.
