AbstractOne of the most important problems that a teacher faces when using a smart board in the teaching process is the fall of a strong light beam from the projector on their faces and bodies. The focus of this light is harmful to the human eye, which leads to temporary blindness when it falls directly on the eye. It also leads to harmful side effects. The light falling on the presenter body will make the picture on the screen looks unprofessional and unclear and distract the attention of the students. Solving this problem will led to better lectures delivering for both the teachers and the student.
In this study, a system is designed to track the movement of the teacher using an infrared transmitter that is attached to the teacher’s freshness or head cap. Electronic signals directed to an infrared receiver are installed on the front of the projector device in order to send these signals to the computer for analysis according to the proposed algorithms to determine the teacher face position. A black shade square) is placed in the designated and displayed on the smart board where the lighting will decrease on the face and eyes of the teacher, as this shade will be moving with the movement of the transmitter. This method aims to protect the teacher’s eyes from the harmful strong light.
