Description

Interactive electric whiteboard

Technical field the utility model relates to electronic whiteboard, relates in particular to that a kind of cost is low, induction is sensitive, powerful, can pass through the shown option of computing machine, finishes assigned work, carries out the interactive electric whiteboard of man-machine interaction input information.

Background technology is along with computer technology and development of electronic technology, electronic whiteboard is as the use more and more widely of teaching, training equipment, existing C CD induction type electronic blank is because cost is higher, the technical sophistication degree is higher, the electronic induction area is difficult to greatly promote, touch-screen constant resistance formula electronic whiteboard induction structure complexity, material cost is too high, complex operation, electronic whiteboard can not adopt the information of induction generating means indications such as inductance type to determine the position as handwriting pad, control with the electronic signal accepting method, its cost is still higher, limited popularizing of this electronic product, therefore, existing electronic whiteboard product exists the cost height, precision is low, transmission speed is slow, and complicated operation influences problems such as popularization and application.

The summary of the invention the purpose of this utility model is to overcome the deficiencies in the prior art, provide and use the interactive electronic principle of induction, cooperate with computing machine and use, can be implemented in marking Function, memory function are arranged on the electronic whiteboard, reorder function, the on-screen keyboard function, communication function, interactive function, a kind of interactive electric whiteboard of paintbrush function.

The purpose of this utility model is achieved in that a kind of interactive electric whiteboard, it is by electronic whiteboard plate face, electronic signal emission pen, the electronic input signal inducing receiver, the insulator glued membrane, anti-tampering metallic shield sheet, bottom support holder layer constitutes, the electronic signal emission style of writing blank that generates electricity, electronics input inductive coil produces electronic signal, transmit electronic pulse signal by capacitor, electronic input signal inducing receiver, the information of detected electrons signal emission pen, measuring and calculating judges that electronics input induced signal is in electronic whiteboard present position and various duty, by communication interface the electronic data signals of calculating is transferred to computing machine, one group of complete electronics input induced signal is pressed by instruction by computing machine and instructed, by receiving, editor's storage, arrive record again and show, print, reach the acquisition process of whole electronic induction signals with this until sending.

Described electronic input signal inducing receiver is received control identification circuit electronic signal emission pen, and the sub-blank ejected electron induced signal of pressure electric shock is judged by COMPUTER DETECTION, thereby more properly discerns the position of input signal.Realize complete electronics input induced signal, show the acquisition process overall process that sends by the command reception storage print.

Described electronic signal emission pen also has the MousePen function, and table for computer surface information Display projector to interactive electric whiteboard, can be used electronic signal emission pen control computer on blank.

Principle of work: interactive electric whiteboard is a kind of man-machine interactive input equipment of finishing the work of appointment with shown option on finger or electronic signal emission style of writing and the screen.The interactive electric whiteboard surface is covered on the conductive layer of a rigidity by a resilient membrane of conducting layer, when certain a bit is under pressure, two membranes causes short circuit in this, controller detects the coordinate figure of pressure spot, the position that i.e. finger or electronic signal emission style of writing reaches, send into computing machine through interface, carry out acquisition process by programming by computing machine.

A kind of interactive electric whiteboard of the utility model is recorded in computing machine with blank institute content written former state, can be singly doubly record be entered playback to four times speed.Can also print immediately or send, record is transferred on the far-end computer application such as also interactive, communication and teleconference function realization Web conference, discussion, design, teaching by Email.To become the main means of following long-distance education and training, modernized multimedia teaching, meeting demonstration.
