ABSTRACT

The main stream of presentation is interrupted because of the direct manipulation of their PC frequently so as to control the screen and file open and so on. A variety of products have been developed to solve these inconveniences of the conventional laser beam pointer [LBP] by simply adding a mouse function to the previous LBP. However, the LBPs fully supporting a mouse function are not yet appeared. In this paper, we developed the LBP fully fulfilling a mouse function using mono-camera as well as a robust image processing and analyzed the position detection accuracy. Finally we verified the developed LBP does not only fulfill a mouse function but also solve the defects of the current laser pointer such as inconvenient installation and position detection errors due to the illumination and viewing direction changes
