Background
The Laser page turning pen in the prior art is commonly called an electronic pointer with remote control (Laser pointer), is a novel PPT page turning pen specially designed for computers and multimedia projectors, and is widely used in multimedia teaching and training.
The laser page turning pen can only be used for turning pages of PPT back and forth and mapping laser beams in a playing state.
The limitation of the common PPT laser page turning pen is discovered by students in one teaching activity, and the current scene is that a teacher has to interrupt speech when intending to play a video inserted in the PPT, and then a computer clicks a video playing key with a mouse pointer.
The Track Point pointing stick is a small red cap in a mouse pointer positioning device diagram mainly applied to a notebook computer.
When the small red cap of the pointing rod is slightly pressed by a finger, the ceramic plate at the lower part of the pointing rod is slightly deformed, the resistance of the ceramic plate is changed along with the slight deformation, different electric signals are generated, and therefore different moving directions, moving speeds and positions of the mouse pointer are judged.
In order to avoid the drift of the mouse pointer caused by the random change of the finger pressure, a technology named Negative Inertia can be introduced, so that the pointing rod is not too violent when receiving the reaction of the external force, and the movement of the mouse pointer is more moderate, stable and accurate.
