Abstract- Instructors frequently teach using white board with a pen. This methods has many advantages (e.g., ability) to present the process of problem solving that provides interactive teaching and easy to hold and write on the board to that instructor can response to the students feedback that cannot be replaced by presentation system. However it also have some limitation, e.g., limit the afectivity and the efficiency of the teaching process, lack of recording capabilities. The use of documents camera is preferable but it is limited due to its unaffordable cost for teaching purpose especially in developing countries. This paper describes a low cost classroom technology in supporting teaching through the available low cost document camera. Here, i report on development of the document presentation system that provides not only general document camera features such as camera control, recording and simple image processing but also a augmented reality capability to display three dimensional (3D) objects
