Background technique

The existing operating tools used simultaneously with PPT have certain limitations. First, it is limited to a single-line sequence and can only be used to turn pages forward and backward. There are also certain requirements for the operating distance; and the laser pointer is not convenient to carry and is easy to lose. In addition, the laser has certain harm to the human body, so it is destined not to be widely used for a long time. In teaching, traditional multimedia equipment such as mouse and keyboard are limited. The scope of activities of the educators is limited, which leads to the inability of educators to carry out teaching work in some places in the classroom. At present, some teaching systems have applied somatosensory devices, which use somatosensory devices to recognize gestures to control the page turning of PPT. LeapMotion can be used to achieve One finger flips the PPT page, but the somatosensory device is easily affected by the environment, which makes the application interference and cannot achieve the desired effect. However, Leap Motion cannot replace the role of the mouse and keyboard, but can only work with them. For these somatosensory devices, this problem can be solved to a certain extent, and if educators want to be able to control the presentation in all directions of the classroom, it is impossible to use these somatosensory recognition devices affected by the area. The range is also greatly affected by the complex environment of the classroom, resulting in the unrecognizable problems of these somatosensory devices to a certain extent.
