Description

The antenna arrangement of EM induction system and coordinate localization method thereof

Invention field

The present invention relates to a kind of EM induction system, particularly relate to a kind of antenna arrangement and coordinate localization method thereof of EM induction system.

Background of invention

Because the handwriting identification circuit arrangement can replace mouse, and be more suitable in allowing the user, so the improvement of handwriting identification circuit arrangement is the rapid field of development in recent years with artificial input mode input characters and pattern than mouse.Handwriting identification circuit arrangement the earliest can be considered mouse is replaced with pen, and in order to promote user's operation ease, and normally the two replaces mouse with time writer and digiboard (tablet), and usually with the left button of the corresponding mouse of nib of time writer.Year more than though traditional pen type input product has been gone, yet like product all only biases toward in the application of simple functions such as drawing or input in Chinese.

Traditional EM induction system has the transducer/cursor device of the pattern of a digiboard and a mouse or pen.As everyone knows, determine a described point equipment that two kinds operating mode is arranged in the lip-deep position of electromagnetism digiboard.A kind of is relative pattern, and another kind is an absolute mode.General mouse device is with relative mode operating.When mouse slided on the digiboard system surfaces, computer system received the input from mouse.Can only this mouse of identification relatively moving in X and Y direction.A kind of general technology is to utilize an induction installation forming a pair of orthogonal figure signal in this mouse, and this is to signal moving corresponding to the vertical and horizontal of this mouse.Similarly, the cursor device in the digiboard system, for example time writer generally operates under absolute mode.If mention this cursor device, and when moving to the lip-deep another location of its digiboard of supporting, for this computer system, its signal will change, so that reflect the new absolute position of this cursor device.Now, several different methods is with deciding this cursor device in the lip-deep position of the digiboard of its support, and the technology that wherein is widely used in absolute mode is a kind of technology of electromagnetic induction.

Early stage transducer/cursor device is connected to digiboard by multiconductor cable, and through cable thus, and the information of position and button/pressure is sent in the computer system.Electromagnetic transduction/cursor device in some conventional art was once transmitted the non-orientation state of transducer/cursor device function by frequency of utilization and/or phase change.Usually these functions have: the pressure of the button of pressing, pen, or similar function etc.Yet if there is not scrupulous processing, the change of frequency and phase place is easy to because multiple external factor as metal, noise, electromagnetic wave or the like, thereby reads signal with leading to errors.Particularly on bigger digiboard, it is more and more obvious that these problems can become.The technology of the digiboard system of tradition improvement allows the user to use described point equipment under double mode running, under user's control, can provide to relatively move or the information of absolute position.

Existing pen type input product normally is a kind of electromagnetic induction circuit arrangement.With reference to shown in Figure 1, this figure is the circuit block diagram of an existing electromagnetic induction device.Electromagnetic induction device comprises: a time writer and a digiboard (digital tablet).Have a concussion circuit of being formed by inductance capacitance (LC) in the time writer, when touching nib, will produce the variation of inductance value, thereby make electroshock swing frequency also to change thereupon.The pressure of collision nib is big more, and then the variation of inductance value is big more, thereby the variable quantity of concussion frequency is big more, so imposed on the size of pen point pressure as can be known by the size of frequency variation.Two switch keys are also arranged on the side of time writer, leave and produce changes in capacitance in the inductance capacitance oscillator, thereby change the transmission frequency of pen, change to predict the switch key that the user presses by the difference of frequency by the joint of button.In addition, digiboard (tablet) has also comprised elements such as detecting device (detector), amplifier (Amplifier), analog-digital converter.The middle section of the handwriting pad of this quasi-tradition is a loop inductance, has with the equidistant unidirectional antenna of arranging of array way the two-sided of loop inductance.The main application in this unidirectional antenna loop only is to receive the electromagnetic wave signal that the special electromagnetic pen is launched.When the time writer launching electromagnetic wave, unidirectional antenna will receive this electromagnetic wave, and utilizes the mode of electromagnetic induction to obtain relevant information via digiboard.General its resulting coordinate accuracy rate is not good usually with the traditional antenna arrangement and the mode of input, thereby reduces the usefulness and the return rate of central processing unit.So far, be still one of this most important developing goal in field for how improving the coordinate accuracy rate.

Summary of the invention

The present invention is in order to strengthen and the coordinate accuracy rate and the usefulness thereof that increase the traditional electrical magnetic-inductive device, a kind of antenna arrangement and coordinate localization method thereof of EM induction system are provided, and this method can increase and improve the coordinate accuracy rate and the usefulness thereof of traditional electrical magnetic-inductive device.
