Hossein Ebrahimpour-Komleh, Meysam Tekiyehband · 2009
In this paper, we introduce an interactive whiteboard system using image processing and computer vision techniques. This system is more portable than other similar interactive systems, because the system only needs a computer, laser pointer and a camera to communicate with the user. Using a standard laser pointer, user can send his/her commands to the whiteboard, and the system tracks the light and interpret the commands using a video camera and a software based on machine vision algorithms, then user's commands transmitted to the computer and system executes necessary operations. User's command are the normal mouse activities including clicking on the various menu items and executing certain operations such as zoom or rotate of pictures and so on.
