LT Brush records lectures to play them to the student after class

Chinese designer Lu Yin has come up with a rather strange concept to revolutionize the classroom learning. His concept is based on the duster (blackboard eraser) and the blackboard we used back in our school days. With classroom teaching going digital with time, the concept dubbed the LT Brush could find place in the classrooms making things simpler for the students. Using a camera and a recording pen to scan the courseware which the teacher has written on the blackboard, the LT Brush lets the student record the teachers lecture which the student can playback after the class.
