Key touches virtual key by time writer point to realize interactive operation, such as replaces person's handwriting color, replace handwriting thickness, create, protects
It deposits, the routine operations such as shutdown.The embodiments of the present invention improve online writing interactive experience, facilitate change when writing offline
The routine operations such as person's handwriting color and thickness are stored, it is very easy to use.
The clipboard system of the electromagnetic induction virtual key of the utility model uses above-mentioned clipboard, having the same beneficial
Effect.
Detailed description of the invention
Fig. 1 is that figure is arranged in the region of clipboard；
Fig. 2 is functional module structure schematic diagram；
In figure: 1- writes region；2- virtual key region.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
Simple clipboard shows writing or painting without display screen, and there are two types of usage scenarios, is detached from application
Software is used alone and fit applications software is write online.When exclusive use, written handwriting is stored in board hardware memory
In；When online writing, written handwriting is stored in mobile phone or computer.Currently, this board have a problem that be exactly
Interactive experience is poor when line is write.For example, needing to answer when user wants to switch application end written handwriting color, written handwriting thickness
With doing corresponding operation on software, but time writer is held in hand to do some contact actions very inconvenient；It is soft to be detached from application
When part is used alone, it is even more impossible to switch the color and handwriting thickness of storage person's handwriting.
The working principle of time writer is that time writer does not stop to launch outward electromagnetic wave, when time writer is write on board
When, the electromagnetic induction mould group in board captures the coordinate position of time writer in real time, realizes the record of person's handwriting.In conjunction with time writer
Working principle, in view of the above technical problems, the utility model provides a kind of clipboard of electromagnetic induction virtual key.
It is as shown in Figure 1 board in the prior art, area is being write in writing region 1 and setting including being arranged in intermediate
Virtual key region 2 on the right side of domain.2 surface of virtual key area is provided with function button, the quantity and concrete function of function button
Can be specifically arranged according to concrete application scene, for example, may include color replacement key, handwriting thickness replacement key, it is newly-built by
One or more of key, saving button and switching on and shutting down key etc. go to execute routine operation, and online education classroom also may be implemented
On device for answering question correspond to key etc..
The shape of function button can also be configured according to the size in specific virtual key region, may be, for example, round
One or more of shape, rectangular, diamond shape and strip.For example, the bar shaped key of a strip gradient color can be set, no
Same position corresponds to different colors, and the different location of bar shaped key is clicked by time writer, can exchange different colors.
As shown in Fig. 2, being provided with electromagnetic induction mould group below function button, electromagnetic induction mould group passes through signal conversion circuit
