Description

Touch simulation device and touch simulation method

Technical field

The invention relates to a touch simulation device and a touch simulation method.

Background technique

Mobile smart devices such as smartphones have become an indispensable item in people's work and life because of their convenience and rich application functions. As smartphone hardware specifications become more powerful, its computing storage capacity has approached or surpassed that of personal computers. Many applications that were running on personal computer systems have been able to run completely on smartphones. It can be said that smartphones can be used to some extent. Replace the personal computer. Due to portability requirements, smartphone screens are typically sized to a smaller size, such as less than 5 inches, which limits the use of smartphones in applications where larger display sizes are required.

Currently, smartphones usually have an HDMI video output that can project the content displayed on the phone screen to other screens. Other methods, such as Apple's proprietary Airplay mirroring technology, or some technical alliances such as DLNA, Miracast, etc., can also project the content displayed on the screen of the mobile phone to other screens to solve the size of the screen of the mobile phone. Small but not applicable in some cases.

For example, the content displayed on the mobile phone can be projected onto a large-sized TV or projector through the HDMI interface of the mobile phone. At this time, compared with the operation through the touch screen of the mobile phone, people prefer to directly touch the large screen to realize the control of the display content. Many large-size display devices currently have touch functions, but how to effectively transfer the touch manipulation commands obtained from the large screen to the mobile phone is a challenge.

For example, more and more drivers use navigation software running on mobile phones to replace the dedicated large-screen car navigation system embedded in the car. However, due to the small size of the mobile phone and the remote location of the mobile phone, the driver may have a certain negative impact on the safety of the mobile phone when operating the mobile phone. The Honda car produced by Honda can project the screen display content of the mobile phone to the screen of the car display device through the HDMI interface to solve the problem of small display size of the mobile phone, but the connection is not supported in the car. The phone is controlled on the display device.

The above problem of controlling the mobile phone can be classified as a remote control of the mobile phone problem. One of the current common solutions is shown in Figure 1. Touch control commands at the trigger control command originating end (such as a television, a touch action on a large-screen display of a vehicle) pass through a specific communication channel and a communication protocol (such as TCP/IP). Protocol, WIFI protocol, Bluetooth HID protocol, USB protocol, etc.) is connected with a computer system (here, a mobile phone or a tablet computer can be regarded as a form of computer system), and the touch control command partially or completely bypasses the touch system of the mobile phone touch screen. Directly delivered to the interface processing unit of the mobile phone, the mobile phone runs corresponding functions according to the received touch control instructions, such as opening an application, flipping pages of the browser, and the like.

However, the solution shown in FIG. 1 is limited by the operating system used by the mobile phone (currently mainstream mobile operating systems include Android, IOS, Windows, etc.), and the openness and openness of the communication interface. For example, Google's Android operating system, due to its openness, mobile phone manufacturers will be based on the native Android system for custom development, and whether to support and / or open the communication interface, depending on the different product strategies of various vendors. Another example is the IOS operating system developed by Apple for mobile phones and tablets. Due to the requirements for experience and information security, the IOS system itself does not open all or part of the functions based on the above protocols. As can be seen from the above two mainstream operating systems, there is a large compatibility and consistency problem by directly communicating with the mobile phone by bypassing the touch panel, and in some cases, it is impossible to implement, even if it can be implemented, it needs to be paid. Larger cost.

Another limitation of the solution shown in FIG. 1 is that since the above communication protocol (such as the Bluetooth HID protocol) is not designed for the touch operation of the mobile phone, the transmission method of the touch control command usually loses the multi-touch control of the mobile phone. This feature, which affects the functionality of the application, while reducing the user experience.

In addition, another possible touch control instruction delivery method can circumvent the above compatibility and experience problems. Use a robot with fingers and joints instead of human hands, as shown in Figure 2. If the robot has multiple fingers, the system can support multi-touch operation on the touch screen, which preserves the good operating experience due to multi-point operation. The robot needs to realize the touch operation through the physical movement of the joint, and has certain requirements for the operation space. In addition, as the demand for touch points increases, the hand index of the robot must also increase, resulting in a larger size and weight of the robot.

3 and 4, a touch simulation device according to an embodiment of the present invention includes: a plurality of transmitting powers The pole 10, the plurality of receiving electrodes 20, and the signal processing circuit 30.

The plurality of emitter electrodes 10 are spaced apart in the first direction. Each of the emitter electrodes 10 extends in the second direction. In the present embodiment, each of the emitter electrodes 10 has an elongated shape, but the present invention is not limited thereto. In the present embodiment, the first direction and the second direction assume a substantially vertical arrangement, but the invention is not limited thereto. Further, the number of the emitter electrodes 10 in the present invention is not limited to that shown in FIG. 3. For example, the number of the emitter electrodes 10 may be one.

The plurality of receiving electrodes 20 are spaced apart in the second direction. Each of the receiving electrodes 20 extends in the first direction. In the present embodiment, each of the receiving electrodes 20 has an elongated shape, but the present invention is not limited thereto. Further, the number of the receiving electrodes 20 in the present invention is not limited to that shown in FIG. 3. For example, the number of the receiving electrodes 20 may be one.

It should be noted that the transmitting electrode 10 and the receiving electrode 20 of the present invention are arranged in a mutually intersecting manner, but the present invention is not limited thereto, and for example, the two may be arranged by other suitable types of arrangement.

Each of the transmitting electrodes 10 and each of the receiving electrodes 20 is separated by an electrolyte, that is, each of the transmitting electrodes 10 and each of the receiving electrodes 20 is electrically insulated.

Each of the plurality of transmitting electrodes 10 and each of the plurality of receiving electrodes 20 are connected to the signal processing circuit 30. The signal processing circuit 30 is also coupled to an external touch control command initiating terminal 40 to cause the signal processing circuit 30 to receive a touch control command generated by an external touch control command initiating terminal 40 from an external touch control command initiating terminal 40.

FIG. 5 is a schematic diagram of a touch simulation device for performing touch simulation on a touch device using an embodiment in accordance with the present invention. In FIG. 5, only two transmitting electrodes 10 and one receiving electrode 20 are shown for convenience of explanation. Of course, it should be understood that the other transmitting electrodes 10 and receiving electrodes 20 are equally applicable to the touch simulation principle shown in FIG.

3 to 5, when a touch simulation device for a touch device (or touch sensitive device) 100 is subjected to touch simulation using a touch simulation device according to an embodiment of the present invention, a touch simulation device according to an embodiment of the present invention is generally disposed at To be touched on the device 100. For example, a touch simulation device according to an embodiment of the present invention directly fits on the device to be touched 100; or a touch mode according to an embodiment of the present invention The pseudo device is suspended on the device to be touched 100. For example, the touch simulation device according to an embodiment of the present invention has an extremely short distance between the device to be touched 100, and the extremely short distance does not affect the effect of the touch simulation.

When the signal processing circuit 30 does not receive the touch control command from the touch control command initiating terminal 40, the signal processing circuit 30 does not apply an electric field to the two transmitting electrodes 10. Since the size of the transmitting electrode 10 is small, an electric field change that is sufficient to affect the determination of the touch behavior by the device to be touched 100 is not generated, and the device 100 to be touched does not report the touch behavior. Here, the magnitude of the electric field applied to the emitter electrode 10 can be adjusted statically or dynamically depending on the application requirements. In some practical scenarios, the device to be touched 100 identifies the pressing force of the touch device according to the magnitude of the electric field change. In the above scenario, this characteristic of the adjustable electric field size is very useful.

The receiving electrode 20 receives a pulse synchronizing signal from the driving line 120 inside the device to be touched 100 by electric field induction, and the pulse synchronizing signal is subjected to necessary signal processing such as amplification, shaping, phase shifting, and the like in the signal processing circuit 30. When the signal processing circuit 30 receives the touch control command from the external touch control command initiating terminal 40, as a touch action is generated at the sensing point A position, the signal processing circuit 30 processes the pulse synchronizing signal from the receiving electrode 20 into The electric field signal is synchronized, and the synchronous electric field signal is applied to the corresponding emitter electrode 10 of the sensing point A. Due to the presence of the synchronous electric field signal, the sensing circuit 140 inside the touch device 100 generates an electric field change sufficient to determine that the touch action occurs. At this time, the touch device 100 will report a touch operation at the position of the sensing point A. At the same time, the signal processing circuit 30 does not apply a synchronous electric field signal to the other transmitting electrode 10 (ie, the transmitting electrode corresponding to the sensing point B), and the electric field of the sensing point B remains steady, and the device 100 is not to be touched. The report has any touch on the sensing point B. The above process implements a simulation of the touch behavior (ie, single touch behavior) of the touch control command at a specified location on the device to be touched 100.

When the simulation of the drag behavior is implemented, for example, the analog touch point is dragged from the sensing point A to the sensing point B. The signal processing circuit 30 processes the pulse synchronization signal from the receiving electrode 20 into a synchronous electric field signal according to a touch control command from the external touch control command initiating terminal 40, and first applies a synchronous electric field signal to the transmitting electrode 10 corresponding to the sensing point A. And then applying a synchronous electric field signal to the transmitting electrode 10 corresponding to the sensing point B, while gradually canceling the application of the synchronous electric field signal of the transmitting electrode 10 corresponding to the sensing point A, and maintaining the transmitting electrode 10 corresponding to the sensing point B The application of a synchronous electric field signal. Assuming that the sensing point A and the sensing point B are physically adjacent, the device to be touched 100 and the computer system determine a dragging behavior from the sensing point A to the sensing point B. The above process realizes the simulation of drag and touch behavior between two sensing points. It should be understood that the drag can be implemented between multiple sensing points Control simulations to achieve larger and more complex drag operation simulations.

For example, when the multi-touch operation simulation is implemented, the signal processing circuit 30 receives the multi-touch control command from the external touch control command initiating terminal 40, and processes the pulse synchronizing signal from the receiving electrode 20 into a synchronous electric field signal, while A synchronous electric field signal is applied to the transmitting electrode 10 corresponding to the sensing point A and the transmitting electrode 10 corresponding to the sensing point B, and the touch device 100 simultaneously senses the touch behavior on the sensing point A and the sensing point B. The example gives a two-point operational simulation of two emitter electrodes 100 and corresponding sense points, it being understood that in practice a multi-point operation simulation of more electrodes and corresponding sense points can be included.

6 is a circuit configuration diagram of a signal processing circuit in accordance with an embodiment of the present invention. In FIG. 5, for convenience of explanation, only a schematic diagram showing the connection of the two transmitting electrodes 10 and one receiving electrode 20 to the circuit configuration of the signal processing circuit 30 is shown. Of course, it should be understood that the other transmitting electrode 10 and receiving electrode 20 can be connected using the circuit connection structure shown in FIG.

Referring to FIG. 6, a signal processing circuit 30 according to an embodiment of the present invention includes a micro processing unit (MCU) 32, a preamplifier circuit 340, a post stage amplifying circuit 360, and a post stage amplifying circuit 380. It should be understood that as the number of the emitter electrodes 10 increases and the number of the receiving electrodes 20 increases, the number of the preamplifier circuit 340, the post stage amplifying circuit 360, and the post stage amplifying circuit 380 increases correspondingly.

The micro processing unit 32 has an instruction receiving port 321 and output control pins s1, s2. The instruction receiving port 321 is connected to an external touch control command initiating terminal 40 for receiving a touch control command issued by an external touch control command initiating terminal 40. The preamplifier circuit 340 is connected to the corresponding receiving electrode 20. The post-amplifier circuit 360 is connected to the corresponding preamplifier circuit 340, the corresponding output control pin s1, and the corresponding emitter electrode 10 (for example, the emitter electrode corresponding to the sense point A). The post-amplification circuit 380 is connected to the corresponding preamplifier circuit 340, the corresponding output control pin s2, and the corresponding emitter electrode 10 (eg, the emitter electrode corresponding to the sense point B).

The micro processing unit 32 controls the preamplifier circuit 340 and the post stage amplifying circuit 360 and/or 380 to process the pulse synchronizing signal supplied from the receiving electrode 20 into a synchronous electric field signal according to the touch control command, and the transmitting electrode 10 corresponding to the sensing point A And/or the transmitting electrode 10 corresponding to the sensing point B applies a synchronous electric field signal, which affects the electric field distribution of the device to be touched 100, thereby realizing the simulation of the real touch behavior without physical motion.

In summary, according to an embodiment of the present invention, finger touch simulation of a touch sensitive device such as a touch screen is realized without physical motion, and simulations of actions such as multi-touch, drag, click, and double-click are supported. The invention solves the problem that the space above the touch screen is not allowed, or the touch sensitive device such as the touch screen is operated under the situation that the hand is inconvenient to operate, and the difference in the openness and support degree of the operating system and the protocol of different mobile phones is avoided. Compatibility issue.

While the invention has been shown and described with respect to the specific embodiments the embodiments of the invention Various changes in details.
