双模输入设备和双模输入方法Dual mode input device and dual mode input method

技术领域technical field

本发明属于电数字设备领域，涉及一种手写设备和手写设备输入方法，具体涉及一种电磁电容双模输入设备和电磁电容双模输入方法。The invention belongs to the field of electric digital equipment, and relates to a handwriting equipment and a handwriting equipment input method, in particular to an electromagnetic capacitance dual-mode input equipment and an electromagnetic capacitance dual-mode input method.

背景技术Background technique

电磁手写设备是通过发送电磁波由电磁笔感应该电磁波并产生谐振信号的方式来检测笔的坐标位置，电容触摸屏是通过检测手与电容屏的电容变化来检测手的坐标位置，将二者结合起来就可以实现用手点击和用笔操作的两种输入模式。但是如果电磁板一直工作的话，发送的电磁波对电容触摸屏有干扰，所以目前通常采用分时扫描电容屏与电磁屏的方式。但是，该方式中，在切换到扫描电磁屏工作状态时，是通过间隔扫描发送线圈与接收线圈的方式检测是否有电磁笔的输入信号，因此扫描时间较长，不利于实现电磁手写设备在分时扫描时的快速切换。The electromagnetic handwriting device detects the coordinate position of the pen by sending electromagnetic waves, which are sensed by the electromagnetic pen and generates a resonance signal. The capacitive touch screen detects the coordinate position of the hand by detecting the capacitance change between the hand and the capacitive screen, and combines the two Two input modes of clicking with a hand and operating with a pen can be realized. But if the electromagnetic board is working all the time, the transmitted electromagnetic waves will interfere with the capacitive touch screen, so the method of time-sharing scanning of the capacitive screen and the electromagnetic screen is usually used at present. However, in this method, when switching to the working state of the scanning electromagnetic screen, it is to detect whether there is an input signal of the electromagnetic pen by scanning the sending coil and the receiving coil at intervals, so the scanning time is long, which is not conducive to realizing the electromagnetic handwriting device in a separate Fast switching while scanning.

另外，本发明的双模输入设备的双模输入方法中，所述双模输入设备包括：电磁笔，和手写板，其具有作为第一输入板的、具有多个发送线圈和多个接收线圈的电磁板，和第二输入板；所述双模输入方法的特征在于，包括：同时接通所述多个发送线圈，并对所述多个接收线圈进行扫描，以检测所述电磁笔的输入动作的电磁笔输入动作检测步骤，在检测到所述电磁笔的输入动作时，切换到电磁板扫描过程；在未检测到所述电磁笔的输入动作时，切换到第二输入板扫描过程。In addition, in the dual-mode input method of the dual-mode input device of the present invention, the dual-mode input device includes: an electromagnetic pen, and a handwriting tablet, which has a plurality of sending coils and a plurality of receiving coils as the first input board An electromagnetic board, and a second input board; the dual-mode input method is characterized in that it includes: simultaneously connecting the multiple sending coils, and scanning the multiple receiving coils to detect the electromagnetic pen The electromagnetic pen input action detection step of the input action, when the input action of the electromagnetic pen is detected, switch to the electromagnetic board scanning process; when the input action of the electromagnetic pen is not detected, switch to the second input board scanning process .

根据本发明的双模输入设备，由于在接通多个发送线圈的情形下扫描接收线圈，从而能够快速检测到电磁笔的输入操作，节省双模输入设备在等待用户输入操作时对第一、第二输入板上的输入动作进行检测的时间，从而在检测到用户输入操作时能够快速进入相应输入模式，因此扫描时间短，利于实现电磁手写设备在分时扫描时的快速切换。According to the dual-mode input device of the present invention, since the receiving coil is scanned under the situation of connecting multiple transmitting coils, the input operation of the electromagnetic pen can be quickly detected, saving the first, The time for detecting the input action on the second input board can quickly enter the corresponding input mode when the user input operation is detected, so the scanning time is short, which is beneficial to the rapid switching of the electromagnetic handwriting device during time-sharing scanning.

具体实施方式Detailed ways

下面，结合附图详细说明本发明的具体实施方式。Hereinafter, specific embodiments of the present invention will be described in detail in conjunction with the accompanying drawings.

如图1所示，本实施方式的双模输入设备100包括，主控制模块101；手写板102；和向外部设备输出控制信息的通讯接口105。其中手写板102具有两种不同输入模式的输入板，第一输入板103可以是电磁板，第二输入板104，比如，可以是电容屏输入板。As shown in FIG. 1 , the dual-mode input device 100 of this embodiment includes a main control module 101 ; a tablet 102 ; and a communication interface 105 for outputting control information to external devices. The handwriting pad 102 has two input pads with different input modes. Thefirst input pad 103 may be an electromagnetic pad, and the second input pad 104 may be, for example, a capacitive screen input pad.

如图2所示，在手写板102中，电容屏输入板104叠放在电磁板103的上方，在电容屏输入板104的上方设置外壳102a，在电磁板103的下方设置底壳102b。As shown in FIG. 2 , in the handwriting panel 102 , the capacitive touch panel 104 is stacked above theelectromagnetic panel 103 , the shell 102 a is set above the capacitive touch panel 104 , and the bottom shell 102 b is set below theelectromagnetic panel 103 .

图3为本发明一个实施方式中电磁板的模式图。Fig. 3 is a schematic diagram of an electromagnetic board in one embodiment of the present invention.

如图3所示，电磁板103具有多个发送线圈103a和多个接收线圈103b，发送线圈103a与接收线圈103b相互垂直排列，在主控制模块101控制下被扫描，以检测具有谐振电路的电磁笔的位置。电容屏输入板104与现有的电容屏输入板构成相同，能够检测用户手指触摸的位置。在主控制模块101的控制下，在用户使用电磁笔进行输入操作时，启动电磁板103，在用户用手指进行输入操作时，启动电容屏输入板104。但由于在用手指操作时，电磁板103中发送线圈103a所发送的电磁波会对电容屏输入板104产生干扰，不能准确地检测手指触摸位置，因此在启动电容屏输入板104时需要停止对电磁板103中发送线圈103a的扫描。As shown in Figure 3, theelectromagnetic board 103 has a plurality of transmittingcoils 103a and a plurality of receivingcoils 103b, the transmittingcoils 103a and the receivingcoils 103b are arranged perpendicular to each other, and are scanned under the control of the main control module 101 to detect electromagnetic waves with a resonant circuit The position of the pen. The capacitive touch input board 104 has the same structure as the existing capacitive touch input board, and can detect the position touched by the user's finger. Under the control of the main control module 101, when the user uses the electromagnetic pen to perform an input operation, theelectromagnetic board 103 is activated, and when the user performs an input operation with a finger, the capacitive screen input board 104 is activated. But because when operating with fingers, the electromagnetic waves sent by the transmittingcoil 103a in theelectromagnetic board 103 will interfere with the capacitive touch screen input board 104, and the finger touch position cannot be accurately detected. Scanning of the sendingcoil 103a in theboard 103 .

在用户没有进行输入操作时，本实施方式的双模输入设备100等待用户再次输入，并且检测用户是用电磁笔进行输入还是用手指进行输入。因此，双模输入设备100中对电磁板103和电容屏输入板104进行分时检测。比如，在用户完成本次输入后，经过规定时间若仍未继续输入操作，则开始对手写板102中的电磁板103和电容屏输入板104分时检测。When the user does not perform an input operation, the dual-mode input device 100 of this embodiment waits for the user to input again, and detects whether the user performs input with an electromagnetic pen or with a finger. Therefore, the dual-mode input device 100 performs time-sharing detection on theelectromagnetic board 103 and the capacitive screen input board 104 . For example, after the user completes this input, if the input operation has not been continued after a specified time, theelectromagnetic board 103 and the capacitive screen input board 104 in the handwriting pad 102 will start time-sharing detection.

在步骤S301和步骤S302中进行电磁笔的检测。在S301中，主控制模块101关闭电容屏输入板104，同时接通电磁板103中的多个发送线圈103a。然后，在步骤S302，主控制模块101对多个接收线圈103b进行扫描，检测是否有电磁笔的输入动作。The electromagnetic pen is detected in step S301 and step S302. In S301 , the main control module 101 turns off the capacitive screen input board 104 , and simultaneously turns on themultiple sending coils 103 a in theelectromagnetic board 103 . Then, in step S302, the main control module 101 scans the plurality of receivingcoils 103b to detect whether there is an input action of the electromagnetic pen.

与以往不同，在本实施例中，在进行电磁笔输入动作检测时，接通多个发送线圈103a，然后对接收线圈103b进行扫描。在接通多个发送线圈103a的情形下，在电磁板103的整个表面上都存在发送线圈103a所发射的电磁波，此时，若使电磁笔接近，则无论电磁笔位于电磁板103的哪个部分，都会接收到该电磁波，从而电磁笔内部的谐振电路振荡放出二次电磁波。此时若对接收线圈103b进行扫描，则能够检测到电磁笔所放出的二次电磁波，依此能够检测到电磁笔输入动作，并判断为用户开始用电磁笔进行输入。Different from the conventional ones, in this embodiment, when detecting the input action of the electromagnetic pen, multiple transmittingcoils 103a are turned on, and then thereceiving coils 103b are scanned. When a plurality of sendingcoils 103a are connected, there is electromagnetic wave emitted by the sendingcoils 103a on the entire surface of theelectromagnetic board 103. At this time, if the electromagnetic pen is made close, no matter which part of theelectromagnetic board 103 the electromagnetic pen is located on, , will receive the electromagnetic wave, so the resonant circuit inside the electromagnetic pen oscillates and emits a secondary electromagnetic wave. At this time, if thereceiving coil 103b is scanned, the secondary electromagnetic wave emitted by the electromagnetic pen can be detected, and the input action of the electromagnetic pen can be detected accordingly, and it is judged that the user starts to use the electromagnetic pen to input.

如上所述可知，在步骤S301、S302中，能够检测到电磁笔输入开始，却并不能确定电磁笔的位置。但是，在手写板102等待输入的状态下，只需要快速检测到电磁笔的输入，无需对其精确检测。As mentioned above, it can be seen that in steps S301 and S302, the start of the electromagnetic pen input can be detected, but the position of the electromagnetic pen cannot be determined. However, in the state where the tablet 102 is waiting for input, it is only necessary to quickly detect the input of the electromagnetic pen, and it is not necessary to detect it accurately.

在步骤S303中，若检测到电磁笔的输入，则进入步骤S304。在步骤S304中，启动电磁板的输入，主控制模块101开始对发送线圈103a和接收线圈103b进行间隔扫描，从而能够如现有技术那样，精确地检测电磁笔的位置。In step S303, if the input of the electromagnetic pen is detected, go to step S304. In step S304, the input of the electromagnetic board is activated, and the main control module 101 starts to scan the transmittingcoil 103a and the receivingcoil 103b at intervals, so as to accurately detect the position of the electromagnetic pen as in the prior art.

在步骤S303中，若未检测到电磁笔的输入，则进入步骤S305。In step S303, if the input of the electromagnetic pen is not detected, go to step S305.

在步骤S305中，主控制模块101启动电容屏输入板104，开始对电容屏输入板104进行扫描，以检测来自用户手指的输入操作，此时关闭电磁板103，以降低功耗并防止干扰。In step S305, the main control module 101 activates the capacitive touch input board 104 and starts to scan the capacitive touch input board 104 to detect the input operation from the user's finger. At this time, theelectromagnetic board 103 is turned off to reduce power consumption and prevent interference.

在步骤S306中判断是否检测到手指触摸的操作，若检测到手指触摸操作，则进入步骤S307开始利用电容屏输入板进行输入。In step S306, it is judged whether a finger touch operation is detected, and if a finger touch operation is detected, proceed to step S307 to start inputting with a capacitive screen input board.

若在步骤S306中未检测到手指触摸的操作，则返回步骤S301，接通多个发送线圈103a，以重复对电磁笔输入动作的检测。If no finger touch operation is detected in step S306 , return to step S301 , and turn on a plurality of sendingcoils 103 a to repeat the detection of the input action of the electromagnetic pen.

如上所述，在本实施方式中，在检测电磁笔的输入时(步骤S301、S302)，通过接通多个发送线圈103a并对接收线圈103b进行扫描，能够快速检测到电磁笔的输入操作，与以往的对发送线圈103a和接收线圈103b进行间隔扫描来检测电磁笔的输入操作的方法相比，能够大幅缩短检测时间。并且，虽然如上所述，在对电磁笔的输入操作进行检测时不能够检测电磁笔的位置，但只要在检测到电磁笔的输入操作后启动对发送线圈103a和接收线圈103b的扫描(步骤S304)，则能够在很短的时间内启动电磁板的输入，不会影响用户的使用。并且，根据本实施方式，由于大大缩短了检测电磁笔的输入操作时所需要的时间，能够使电磁笔输入动作检测和手指输入检测的周期大幅缩短，从而在检测到用户输入操作时能够快速进入相应输入模式(用电磁笔或用手指)。As mentioned above, in this embodiment, when detecting the input of the electromagnetic pen (steps S301, S302), by connecting a plurality of transmittingcoils 103a and scanning thereceiving coil 103b, the input operation of the electromagnetic pen can be quickly detected, Compared with the conventional method of scanning the transmittingcoil 103a and thereceiving coil 103b at intervals to detect the input operation of the electromagnetic pen, the detection time can be significantly shortened. And, although as mentioned above, the position of the electromagnetic pen cannot be detected when the input operation of the electromagnetic pen is detected, as long as the scanning of the transmittingcoil 103a and thereceiving coil 103b is started after the input operation of the electromagnetic pen is detected (step S304 ), the input of the electromagnetic board can be started in a very short time without affecting the use of the user. Moreover, according to this embodiment, since the time required to detect the input operation of the electromagnetic pen is greatly shortened, the cycle of the detection of the input action of the electromagnetic pen and the detection of the finger input can be greatly shortened, so that when the user input operation is detected, it is possible to enter quickly. Corresponding input mode (with electromagnetic pen or with finger).

另外，在本实施方式中，作为第二输入板以电容屏输入板为例进行了说明，但本领域技术人员能够理解，本发明也同样适用于使用其他输入板代替电容屏输入板制作双模输入设备，例如，可以用电阻输入板代替电容屏输入板，也能够得到同样的效果。In addition, in this embodiment, the capacitive screen input board is used as the second input board as an example for description, but those skilled in the art can understand that the present invention is also applicable to using other input boards instead of capacitive screen input boards to make dual-mode For input devices, for example, a resistive input board can be used instead of a capacitive screen input board to achieve the same effect.
