The great thing about looking back on your school days is knowing that, no matter how old you are now, you were part of some technological revolution. For me, it was desktop PCs and the beginning of laptops. For kids now, it just might be the LT brush by Lu Yin.
The LT brush by Lu Yin stands to digitize the entire classroom experience. This tool resembles the traditional blackboard eraser, but its functionality is on a whole new level. The LT brush features a camera and recording pen that students can use to scan what the teacher has put on the chalkboard, thereby recording the lecture for playback afterwards.
