Abstract

The invention relates to an intelligent blackboard. The blackboard comprises a main body, a projection module, an infrared laser emitter, a depth camera and a function key region. The projection module, the infrared laser emitter, and the depth camera are arranged on the same side of the main body. The projection module is arranged on the upper end of the same side. The infrared laser emitter andthe depth camera are parallelly arranged under the projection module. The function key region is arranged on the other side of the main body. The projection module comprises a variable-focus projection emission end which is capable of rotating for a certain angle relative to the main body. According to the invention, by use of the rotatable projection module, the image of the intelligent blackboard can be obliquely projected on a desktop in an ultra-short focus manner, so a teacher is capable of carrying out motion sensing interaction operation in a detection range of the infrared laser emitter and the depth camera; multiple students can sit around the teacher to observe and demonstrate operation taught by the teacher.

Description

technical field

[0001] The invention relates to an intelligent blackboard, which belongs to the field of teaching computerization. Background technique

[0002] The blackboard is a traditional teaching tool. As an auxiliary tool, the projector plays a very important role in teaching. It can project the images of the lecture content from computers, mobile phones, etc. to the big screen for sharing, especially suitable for classrooms of various capacities. When in use, the teacher operates on the operating side, and the results of the operation are displayed on the shared projection screen in real time. But this brings some problems, firstly, the teacher's position is limited to a corner away from the projection screen, the purpose is to operate the signal source, such as a laptop, or when the teacher uses a laser pointer, the teacher is still controlled by the teacher as opposed to teaching by hand. It is limited to a position far away from the students, and some special ha...
