Description
Technical field
The present invention relates to a kind of intelligent blackboard, belongs to teaching Electronic Data Processing field.
Background technology
Blackboard is a kind of traditional educational aid.Projecting apparatus plays very big effect as aid in teaching, it
The image of lecture content can be projected in big screen from computer, mobile phone etc., for sharing, be particularly suitable for use in various capacity
Classroom.In use, teacher is shown on shared projection screen in operating side operation, the fructufy of operation.But this brings one
A little problems, first, the position of teacher are limited in the corner away from projection screen, in order to operation signal source, example
Such as notebook computer, or when teacher uses laser pen, imparted knowledge to students relative to teach-by-doing, teacher be still limited in apart from student compared with
Remote position, the teaching of some special teach-by-doings can not be carried out, such as when teacher needs operating process closely to demonstrate
To one or several students.In traditional projection teaching, student can only see the movable vernier on screen, and can't see old
The actual hand motion of teacher, such as the interactive operation for touch-screen.On the other hand, in traditional teach-by-doing teaching, by
Limitation in screen size and position, teacher can only typically give lessons to 1-2 positions student simultaneously, and student can only typically watch behaviour
Make, and the rehearsal that can not be operated.Therefore, it is necessary to a kind of educational aid, thus it is possible to vary this present situation, i.e., can both realize large-size screen monitors
Curtain projection, the teaching of teach-by-doing and exchanging closely can be carried out again.
The content of the invention
To solve the above problems, it is an object of the invention to provide a kind of intelligent blackboard, teacher is flexibly used, enter
Capable a wide range of or small range teaching.
Technical scheme is used by the present invention solves its problem：Intelligent blackboard, including main body, projection module, it is infrared swash
Optical transmitting set, depth camera, function button area, wherein projection module, Infrared laser emission device, depth camera are arranged on master
The same side of body, projection module are arranged on the relatively upper end of the same side, and Infrared laser emission device, depth camera are set side by side
In the lower section of projection module, function button area is arranged on the opposite side of main body, and projection module includes varifocal projection emission end, should
Varifocal projection emission end can be relative to body rotation certain angle.
Further, main body is provided with wireless communication module.
Further, the wireless communication module includes bluetooth module and wifi module.
Further, main body is additionally provided with USB interface.
Further, main body is additionally provided with microphone and loudspeaker.
Further, high density lithium polymer battery is additionally provided with main body.
Further, separable laser pen is additionally provided with main body, be provided with laser pen page-turning button, forwarding button,
Back.
The beneficial effects of the invention are as follows：, can be using can be relative to the projection module rotated according to the intelligent blackboard of the present invention
The image of intelligent blackboard by it is ultrashort it is burnt in a manner of tiltedly throw on the table, wherein the image may be from according to the present invention intelligent blackboard
Built-in system application or the electronic installation that remotely connects, such as notebook, server, smart mobile phone etc., now award
Class person can be at Infrared laser emission device, the reconnaissance range of depth camera, such as be sitting in the front of projection screen, carry out body-sensing
Interactive operation, such as Infrared laser emission device, depth camera combination can identify the gesture for the person of giving lessons, and specific gesture can be with
Specific system operatio is mapped, for example, page turning, click, drawing, text input etc., thus the person that do not give lessons can be to pass through gesture (bag
Include touch desktop) control system.Thus, some students can sit around in teacher both sides, such as 1-4 student, with not shadow
Ring student operation and observation, and without departing from Infrared laser emission device, depth camera reconnaissance range premised on, observe and drill
Practice the operation that teacher is instructed.On the other hand, also can be as traditional blackboard or projection screen according to the intelligent blackboard of the present invention
Use, can rotate projection module by function button area or the operation device of such as bluetooth connection remotely connected, teacher
To front projection angle, so that image is projected to general teaching projection screen or metope, recycle what can be separated with main body to swash
Light pen, operated.Further, depth camera can also detect the laser spots being incident upon on screen, realize interactive behaviour
Make, such as laser spots are stopped more than a preset time in same position, will be considered as clicking operation.Therefore, according to the present invention's
Intelligent blackboard greatly extends the function of single projection and single blackboard, breaches the limit of teaching method, in teaching zooming
There is far-reaching prospect of the application and economic prospect in change.
