Description
Technical field
The present invention relates to the meeting board communications field, particularly relate to a kind of meeting board based on point-to-point transmitted in both directions.
Background technology
The definition of board and scope are relatively extensive, everyly can write the plate that letter written with chalk and water-color paintbrush word and some exempt from pen and can be called board, more common conventional be the plastic cement small blackboard etc. of chalk black, water-color paintbrush blank and child.Along with scientific-technical progress, the board of a lot of student or office is all exempted to brush and is exempted from coloured pencil function, and environmental protection cost is low, and in following teaching facilities, chalk black will be substituted gradually, and this is the outstanding contributions of scientific-technical progress and environmental protection.
In daily life at ordinary times and office, maximum be generally blank.
Blank be a kind of can with special white board marker repeated writing and the plastic cement white plane of erasable, be usually used in classroom instruction, panel discussion, with the purposes such as personal note.From about 1994, blank just started to be commonly used, and almost only had blackboard comparatively general before this.
In Taiwan because identical with the popular name of drugs therefore, therefore again normal with " non-blackboard " designate it.Usually comparatively blackboard is expensive for blank, however compared with on blackboard with the chalk dust stayed after chalk-writing, blank wiping easier than blackboard, powder of also can not kicking up during wiping, write figure onboard in addition or word contrast relatively high, these are all the advantages of blank.Blank, because be easier to reflective, is seen more unclear from the people away from blank, and therefore school's great majority use blackboard.
As chalk must be used to write on blackboard, blank is write and must use white board marker.
Along with the development of science and technology, engender a kind of electronic whiteboard---interactive electronic white board, it is the computer inputs of absolute coordinates in itself, digit drawing plate as large-sized in same portion, coordinate values and the state that clicks of person's handwriting user can write in whiteboard surface are sent to computer constantly, interactive electronic white board is owing to being coordinates of input devices, so need to be connected to a computer, and through the projector that computer connects, the picture of computer screen is projected again to be got back on blank, when projector picture returns blank, the general program first must passing through calibration, writing of the person's handwriting of user and electronic whiteboard could be overlapped exactly, to allow user have a kind of directly writing with a pen in the effect of electronic whiteboard surface.Line between computer and blank can be wired.
In the teleconference of company; often there will be the situation being difficult to communication by speech, needing picture or formula to express; this time; the blank of this locality is write picture the other side be difficult to see; even if be shown to the other side by camera video broadcasting to see; the other side also cannot make an amendment on the image had or formula, inconvenience very.
Patent " electronic whiteboard " (application number: 201110306255.7 applyings date: 2011-10-11) discloses a kind of electronic whiteboard, and comprising: panel component, it has the description face for projects images of writing, draw, show, mobile device, moves to reception position or camera site for enabling an arm member, filming apparatus, is arranged on described arm member, and can take described description face when described arm member is in camera site, image processing apparatus, processes for the view data of taking described filming apparatus, output unit, for exporting the view data of described image processing apparatus process, first pick-up unit, is in the information of reception position for detecting described arm member, second detection device, is in the information of camera site for detecting described arm member, control module, for controlling the shooting in described description face, described control module makes described arm member move to camera site by described mobile device, and in response to the information that the described arm member detected by described second detection device is in camera site, the mobile of described mobile device is stopped, then described filming apparatus is made to take described description face, and after the shooting of described filming apparatus terminates, described arm member is made to move to reception position by described mobile device, and in response to the information that the described arm member detected by described first pick-up unit is in reception position, the mobile of described mobile device is stopped, and the information that the movement responding described mobile device has stopped making described output unit output image data.
The method can read the image be depicted on panel, but does not solve in meeting the problem being difficult to carry out interaction with panel.
