Problems solved by technology

In the demonstration teaching, the laser pointer is often used as a pointing tool to mark the demonstration content. However, due to the relatively small luminous power of the laser pointer and the display with high brightness, the projection effect of the laser pointer cannot be displayed.
The above situations will affect the teaching effect of teaching demonstration and consultation film reading to a certain extent.

Abstract

The invention discloses a method for following display of a labeling graph based on a serial port. The method comprises the steps of judging the moveable scope of the graph, receiving and sending the serial port data and judging the correctness of a mouse position according to the attribute of the image color in the scope. According to the invention, on the basis of the serial port technique, the mouse moving track in the visible scope of the screen is accurately recognized, the following movement of the following graph is generated according to the mouse moving track, the drawing and the following display of the labeling graph are realized, some display contents can be highlighted according to the requirements in a demonstration process, and the visibility, accuracy and convenience in displaying the content can be promoted.

Description

technical field [0001] The invention relates to the technical field of dynamic display, in particular to a serial port-based method for identifying and following the movement track of marked graphics. Background technique [0002] With the rapid development of display technology, many displays are used as an indispensable new-generation display tool for large-scale consultation and imaging teaching demonstration, consultation reading, remote consultation, etc. In the demonstration teaching, the laser pointer is often used as a pointing tool to mark the demonstration content. However, due to the relatively small luminous power of the laser pointer and the display with high brightness, the projection effect of the laser pointer cannot be displayed. The above situations will affect the teaching effect of teaching demonstration and consultation film reading to a certain extent. Contents of the invention [0003] The technical problem to be solved by the present invention is: ...
