Description
Technical field
The present invention relates to the method for operating of a kind of interactive electric whiteboard, particularly interactive electric whiteboard.
Background technology
Electronic whiteboard is developed by common blank, along with the development of technology and the needs in market, interactive electric whiteboard occurred.Interactive electric whiteboard can carry out information communication with computer, electronic whiteboard is connected to PC, and utilize projector that the content on the PC is projected on the electronic whiteboard screen, under the support of special application program, can construct a giant-screen, interactively cooperation meeting or teaching environment.Utilize specific pen with means for holding it in right position to replace mouse, can move Any Application, any operation that can edit file, note, preservation etc. utilizes keyboard and mouse to realize on computers at the enterprising line operate of blank.The electronic whiteboard principle of work is divided into two kinds of pressure sensitivity principle and Laser Tracking principles.The touch blank of use pressure sensitivity principle is equivalent to a touch-screen of computing machine, is a kind of human-computer interaction formula input equipment of finishing the work of appointment with shown option on finger or style of writing and the screen.There is two-layer pressure-sensitive film this electronic whiteboard inside, and when whiteboard surface a bit was under pressure, two membranes caused short circuit in this, and the controller of electronic whiteboard detects the coordinate figure of pressure spot, sends into computing machine through the RS232 interface.Use each generating laser of both sides, blank upper end of Laser Tracking principle.After blank started, generating laser sent laser and strafes whiteboard surface, and handtailor pen has induction laser function, thus the position of feedback pen.
This shows, traditional electronic whiteboard defines user's mode of operation, and the demonstrator must use pen with means for holding it in right position contact blank, could control the mobile of cursor in the blank, this just needs the demonstrator to keep constantly and the enough near distance of blank, and this has limited demonstrator's freedom of movement to a certain extent; Simultaneously, for bigger electronic whiteboard, the user is subjected to the restriction of self height condition, can't contact the topmost edge zone of electronic whiteboard; Especially in teaching, see the blank content for the ease of back row student, electronic whiteboard generally is installed in than higher position, like this, for the demonstrator, higher zone, the position comparison difficulty that will become in the contact electronic whiteboard, and the menu of a lot of teaching softwares is positioned at higher zone, position, this will be unfavorable for that the demonstrator operates electronic whiteboard, thereby influence the effect of electronic whiteboard.
In addition, traditional pen with means for holding it in right position function is limited, can only finish basic operations such as mobile, click, and for the operation of more complicated, such as the intercepting of the page, capital and small letter switches, and other function that needs keyboard to cooperate, pen with means for holding it in right position can't be finished, and the function that this just needs the expansion pen with means for holding it in right position makes it be fit to the demonstrator more and uses.
