Abstract

A labeling control method for a wireless presentation device includes: adding an image overlay layer on a presentation graphic interface; receiving a button instruction of the first button, and drawing a label line on the image overlay layer according to the button instruction; After drawing the labeling line, calculate the size of the labeling line, compare the size of the labeling line with a preset first threshold; if the size of the labeling line is smaller than the first threshold, delete the labeling line Or set a labeling area that can contain a preset minimum operating area for the labeling line. The key command of the first button can directly draw the labeling line on the image overlay layer, which can simplify the labeling operation; The marked area of ​​the minimum operation area is set, which makes the deletion operation easier and more convenient.

Description

technical field [0001] The present application belongs to the field of wireless demonstrators, and in particular relates to a wireless demonstrator and a labeling control method and device thereof. Background technique [0002] The wireless presenter is an important device in the conference room, which is used by the speaker to highlight the key content when explaining PPT and other materials. One of the main product categories of wireless presenters is laser presenters, also known as laser pointers, which contain a laser transmitter. The speaker presses the activation button to trigger the laser, and uses the laser point to illuminate the key content on the screen to achieve the purpose of highlighting the key content . In recent years, the price of LCD / LED large screens has been getting lower and lower. Compared with projectors, it has higher brightness, higher contrast, and better color reproduction. Therefore, more and more meeting rooms, classrooms and training rooms b...
