Laser pointer capable of real-time sensing
In the process of popularization of multimedia teaching, there is a general problem of how to introduce modern teaching equipment and the organic combination of teachers' classroom teaching habits. At present, in the process of teaching demonstrations, teachers often need to stand by the computer and explain while operating the computer. For places that need to be emphasized, they must stand up from time to time and give pointers. They originally provide convenient multimedia presentation equipment. , But it has restricted the teachers’ rich classroom language. In order to solve this problem, a laser pointer is designed to assist teaching so that teachers can interact with the computer at a distance by using the laser pointer. The teaching smart Laser pointer has a simple structure. In addition to controlling the laser pointer through buttons, the laser pointer can also be controlled by pressure, heat, infrared signals, etc., and the control signal is coded and transmitted wirelessly, and then connected to the computer The receiving module receives and controls the screen.
