Abstract : Over the years, teaching methodologies have developed from white chalk board to projectors to smart online teaching now. All the practices except projectors involve direct contact with board. In a typical presentation, a presenter has to depend on an operator to control the functionalities of a mouse. And in a worse situation where he has to operate all by himself, he is compelled to interact with a computer more than the audience. This paper aims at developing a handheld laser device incorporated with buttons for left and right clicks to emulate the working of a mouse. A camera captures the image of projected screen continuously. Through Digital Image Processing (DIP), the location of laser is analyzed along with the clicks and this information is communicated to the PC to operate. This project also aims towards the advancement of projector usage by correcting keystone automatically and the tasks of remote control are achieved by commands given by user through keyboard interface. Thus, the remote to control projector can be excluded.
