Application
The laser pointers currently on the market are only a single laser pointer with the function of turning pages of PPT courseware. In class, the teacher has to explain with the PPT and write on the whiteboard, so the teacher often needs to hold two pens in his hand during the lecture. Because I have to hold two pens in my hand, I often use a laser pointer to write when writing on a blackboard. When I turn a page to the PPT, I am holding a whiteboard marker in my hand. In addition, for laser pointers with recording functions currently on the market, teachers need to transfer audio files to the computer. The current method is to transfer the recording files to the computer through a data cable. This requires users to carry a data transmission cable with them. It is very troublesome, it is much more convenient to use Bluetooth technology to transmit, and the mainstream computers on the market currently have the Bluetooth receiving function.
