Abstract
Commercially available wireless presenters have limited functions for presentation with beam projector such as "go to next slide" and "back to previous slide" in an application such as MS PowerPoint. Thus, there is inconvenience associated with carrying out other functions, e.g., execution or termination of an application and maximization or minimization of a window, during the presentation. The objective of this study is to implement a wireless laser pointer mouse that has the same functions as a computer mouse. In order to determine the position of the laser spot in the projector display, image processing that detects the laser spot in the camera image is required. In addition, transformation of the spot position into computer display coordinates is needed to execute computer controls.
