Slide demonstration control device

Abstract

The invention relates to the field of slide control technology, in particular to a slide demonstration control device. The device comprises a camera, a laser pen, an adjustable support, a control module, an infrared projector, an input module, a storage module and a pair of demonstration glasses, wherein the camera is a focus-adjustable camera, the laser pen can emit lasers flickering at different frequencies, functional keys are arranged on the laser pen, different functional keys correspond to different flickering frequencies, the functional keys include an angle correction key and a scale correction key, and the adjustable support is also included and provided with a first stepping motor used for adjusting the pitch angle of the camera and a second stepping motor used for adjusting the yaw angle of the camera. Through the slide demonstration control device, the problem that laser point detection is not accurate due to installation position deviation of the camera can be solved, and meanwhile a user can be helped to perform demonstration smoothly.

Description

technical field [0001] The present invention relates to the technical field of slideshow control, in particular to a slideshow presentation control device. Background technique [0002] In a presentation or meeting, slide presentation software is usually used to present relevant material content through a projector or a large-screen display device. Laser pointers are used in presentations or meetings to indicate what is being said on a projector or large screen. But this laser pointer cannot interact with slide presentation software. Therefore, we often see that people who use laser pointers need to use whiteboards to explain drawings, or to instruct those who operate computers how to operate, or to operate computers by themselves. Obviously, this brings inconvenience to the instructors and makes the explanation process not smooth enough. . [0003] Most of the existing solutions are through the tracking and positioning of the laser point of the laser pointer, and corresp...
