摘要

近年来，投影仪和屏幕正在被大学讲师使用。大教室可能会准备多个投影仪和屏幕来显示主屏幕的相同图像。但是成本很高。本文提出了一种低成本的课堂分配系统。该系统检测主屏幕上的激光指针点，并在移动设备的Web浏览器中输出带有指针光标的幻灯片图像。

A low-cost implementation of lecture distribution system utilizing FPGA and mobile devices

In recent years, projector and the screen is being used by lecturers in the university. The large classrooms might prepare multiple projectors and screens to display the same image of the main screen. But it is high cost. This paper proposes a low-cost implementation of lecture distribution system for classroom. This system detects the laser pointer spot on the main screen and output the slide images with a pointer cursor along with the pointed spot in a mobile device's Web browser.
