Digitizing the Content of a Whiteboard to Aid Traditional Educators and Enhance the Learning Experience of Students

摘要

In this paper, we introduce and implement a device that scans and erases the content written on a whiteboard. The proposed device is directed toward educators who are still comfortable with the traditional methodologies of conducting lectures inside classrooms. The device performs an easy and fast scanning process and then converts the input into an electronic image. The image is stored as a bitmap file on an attached memory device such as an SD card which can be provided to the students for later access. The scanning operation shall help the students concentrate on the lectures and listen carefully to the instructor rather than being distracted by copying the content of the whiteboard on their notebooks. The proposed device is also capable of erasing the whiteboard automatically after it is being scanned to facilitate this operation.
