Embodiment Construction

[0015] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0016] Step 1. The teacher draws the graphics stored in the built-in database of the central server on the blackboard.

[0017] Step 2 Students wear the high-definition camera of the glasses-like device to capture the graphic, and transmit the relevant data to the central server through the wireless network.

[0018] Step 3: The central server performs graphics-related calculations, and transmits the calculation results back to the glasses-like device.

[0019] Step 4 The glasses-like device receives the data and superimposes a virtual image on the glasses display.

[0020] Step 5 Students rotate, zoom and adjust the transparency of the virtual image through the side touchpad of the glasses-like device.

[0021] Optional steps Teachers can add, delete and modify the contents of the central server's built-in database through the relevant softwa...

Abstract

The invention discloses a teaching system based on the augmented reality technology, suitable for emerging education requirements. Under the help of a central processor in a classroom, students wearing spectacle-shaped devices perform full interaction with teaching contents and teachers, so as to get familiar with the teaching contents and cultivate interests. When a teacher draws certain specific figures on the blackboard, cameras of the spectacle-shaped devices worn by the students can send shot figures to a server; the server detects the figures and compares with a database. For example, the teacher draws plane figures of a dam on the blackboard, the spectacle-shaped devices send the figures to the server, the server returns data to the spectacle-shaped devices, and the spectacle-shaped devices superpose the figures on a display screen, so that the students can see a three-dimensional dam figure; through operating a right side touch tablet, the students can rotate and zoom the three-dimensional dam figure, and adjust the transparency of the superposed figure.

Description

technical field [0001] The invention relates to a teaching system, in particular to a teaching system combined with augmented reality technology, which can further improve the expressiveness of teachers in the classroom. Background technique [0002] Augmented reality is one of the research hotspots of many well-known foreign universities and research institutions. AR technology not only has a wide range of applications in application fields similar to VR technology (virtual reality), such as research and development of cutting-edge weapons, aircraft, data model visualization, virtual training, entertainment and art, but also because of its ability to The enhanced display output of the real environment has more obvious advantages than VR technology in the fields of medical research and anatomy training, precision instrument manufacturing and maintenance, military aircraft navigation, engineering design, and remote robot control. Today the scope of AR has expanded to include...
