 Electronic skin is a new type of electronic material invented by American scientists. The key point of this technology is a composite material called QCT (quantum tunnel composite), which can sense the hardness and pressure of the contact object and measure the The hardness and pressure level of the contact object is essentially a piezoelectric sensor that changes its resistance value according to the change of pressure and feeds it back to the internal circuit to let the processor know the specific value of the external pressure. QCT's operating power consumption is extremely low, making it suitable for use on small mobile terminals such as mobile phones. Japanese scientists have also invented a similarly functional electronic skin consisting of rubber, conductive graphite and new transistors. The principle is also that the resistance changes after being subjected to pressure.

Preferred embodiment of the invention

The present invention provides a solution for realizing terminal human-computer interaction, which mainly includes: detecting a resistance value of a corresponding pressure sensing device attached to a terminal housing, wherein the pressure sensing device changes the pressure sensing device according to an external force received. The resistance value, if it is detected that the resistance value reaches a predetermined value, executing a preset application corresponding to the resistance value. For a better understanding of the present invention, the invention will be further described in conjunction with the drawings and specific embodiments.

 1 is a schematic diagram of a terminal according to an embodiment of the present invention. As shown in FIG. 1, one or more pressure sensing devices 11 are attached to a casing of a terminal according to an embodiment of the present invention, and the pressure sensing device 11 can be changed according to an external force received. The terminal of the present invention includes the following modules:

 The resistance detecting module 12 is configured to detect a resistance value of the corresponding pressure sensing device 11, and when detecting that the resistance value reaches a predetermined value, trigger the corresponding application processing module 13;

 The application processing module 13 is configured to execute a preset application corresponding to the resistance value detected by the resistance detecting module 12 after being triggered.

 Wherein, the pressure sensitive device may be an electronic skin or a pressure sensitive crystal attached to the terminal housing. In a preferred embodiment, the resistance detecting module may further include: a first detecting unit and a second detecting unit, wherein the first detecting unit is configured to detect the first event;

 a second detecting unit, configured to detect, after the first detecting unit detects the first event, a resistance value of the pressure sensing device attached to the terminal housing and related to the first event.

 In this embodiment, the terminal only turns on the function of detecting the resistance value of the corresponding pressure sensing device after detecting a certain event.

 For example, after the mobile phone detects an incoming call, it initiates a resistance detection for the "answering" electronic skin. Once it is detected that the electronic skin is pressed by the user, the mobile phone considers that the user has answered the call and answered the call.

 During the call, the phone initiates a resistance test for the "hang up" electronic skin. Once it is detected that the "hang up" electronic skin is pressed by the user, the mobile phone considers that the user has hang up the phone and hangs up.

The resistance detecting module is composed of a resistance detecting circuit and functions to detect a change in resistance of the pressure sensing device corresponding to the resistance detecting module. 2 is a circuit diagram of a resistance detecting module constituting an example of the present invention, and FIG. 2 is an example of a simple circuit for resistance detecting. As shown in FIG. 2, the circuit of the resistance detecting module can be composed of an amplifier 21 and digital logic. The device 22 is constructed. Since the pressure sensing device is connected to the resistance detecting module, the change in the resistance value of the pressure sensing device causes the input resistance detecting module in the circuit. Level change.

 In the example of FIG. 2, an amplifier is coupled to the corresponding pressure sensing device for amplifying a level corresponding to a resistance value of the pressure sensing device and outputting to a digital logic device; the digital logic device, After receiving the level of the amplifier output, if it is determined that the level is greater than the threshold, the trigger signal is output to the corresponding application processing module.

 A voltage limiting device 23 can be connected between the amplifier 21 and the digital logic device 22 to protect the digital logic device.

 Wherein, the signal is amplified by the amplifier at the input level, and the amplification factor should follow a certain capacity. For example, the normal level output of the pressure sensing device is X, and the variation range is o~z, when the change is

When Y or more, it is considered that the user has input through the pressure sensitive device. Digital logic devices (such as XOR gates) have a maximum voltage of A and a threshold voltage of B (when the level is higher than B, the input is considered high, and when it is lower than B, the input is considered low) .

 When the level output of the pressure sensing device is X+Y, the output level after passing through the amplifier should be B. The upper limit of the level limit of the voltage limiting device is A to prevent the level change of the pressure sensitive device from being too large, and the XOR gate is damaged due to the level being too high after the amplifier. In this way, when the level output variation range of the electronic skin is less than Y, the entire circuit has no output, and when the level variation range is greater than Y, the signal is output to the terminal such as the mobile phone.

 The above examples are only a simple example of implementing the method of the present invention, and the purpose is to explain the working principle of the module in the present invention. Those skilled in the relevant art should know that other circuit structures capable of achieving similar functions should also belong to the protection scope of the present invention. .

 In a preferred embodiment, the application processing module may further include: a calculating unit and an executing unit, where

 a calculating unit, configured to calculate an external force corresponding to the resistance value detected by the resistance detecting module according to a preset rule;

 And an execution unit, configured to execute an application corresponding to the external force calculated by the computing unit.

Wherein, in the calculation unit, a calculation table or a calculation formula for storing the correspondence between the resistance value of the pressure sensing device and the external force received by the pressure sensing device, and the calculation unit receives the electricity detected by the resistance detection module The resistance value, that is, the external force received by the corresponding pressure sensing device can be calculated according to the table or formula.

 In another preferred embodiment, the application processing module may further include:

 a playing unit, configured to issue a scene sound corresponding to an application executed by the execution unit.

 The pressure sensing device may be an electronic skin device, or may be some pressure sensitive crystals, wherein the electronic skin may be entirely covered on the outer casing of the terminal, or may be covered by multiple electronic skins respectively on the terminal housing. In some parts, each piece of electronic skin is connected to its corresponding resistance detection module, so that the terminal can more accurately determine the action of the user on the terminal according to the force of different parts, so as to perform according to the prior design. Application, making different reactions.

 For example, an electronic skin with a piezoelectric sensor function can be placed on the top, bottom, keyboard, and left and right sides of the back of the phone. Each electronic skin corresponds to a resistance detecting circuit.

 The designer writes in response to the detected values obtained by the different resistance detecting circuits in the program, for example: When the electronic skin on the left and right sides is subjected to a large pressure, and the back pressure is small, it can be considered that the user is holding the mobile phone hard. At this time, the phone can make a sound like "Don't push me hard, I will hurt". Another example: When there is no pressure on both sides, and the back pressure of the mobile phone is large, it can be considered that the user is using some kind of article or pressing the mobile phone hard. At this time, the mobile phone can emit the sound of “Don't press me hard”;

User's pleasure.

 The integration or covering of the pressure sensing device in the terminal housing of the present invention, such as a pressure sensitive type of electronic skin, is different from the prior art in that the terminal covering material of the prior art does not interact with the internal circuit and the software portion. The electronic skin of the present invention is connected to the internal circuit of the terminal through the terminal housing, so that the characteristic change of the electronic skin is successfully captured by the terminal circuit, and then the terminal software is driven to perform corresponding subsequent operations.

The invention provides a resistance value detecting circuit inside the terminal, and the resistance value detecting circuit is connected to the electronic skin of the terminal casing, and can be detected immediately after the electronic skin resistance value changes. It should be specially stated that the resistance value of the electronic skin is not only related to the force, but also the temperature changes, and other materials contaminated on the electronic skin during use may cause a small change in the resistance value. Unintentional touches by the user may also cause small changes in resistance. Therefore, in the present invention, the electronic skin resistance detecting circuit should have a certain fault tolerance, that is, the intentional operation of the user must be distinguished from other interference situations, and the solution of the present invention is: when the range in which the resistance value changes is small, To do any reaction, you can set a threshold value, do not respond below the threshold value, and move above the threshold value. Due to the difference in the structure of the terminal, there are many ways to implement this function, and details are not described herein.

 In the embodiment of the present invention, the external force received by the terminal casing can be calculated by the resistance value detected by the resistance detecting circuit, and then the calculated external force result is transmitted to other applications of the terminal (for example, it can be a telephone, a screen, a short message, etc. Various software modules and/or hardware modules) enable other applications to respond to different designs through different designs. These reactions can be related to the value of the external force, and can be independent of the value of the external force, such as The resistance value is related.

 According to the above technical solution proposed by the present invention, the terminal can use a small amount of electronic skin and other pressure sensing devices to design a plurality of different effects in different applications and different scenarios, so that the user can exceed the limitation of the keyboard and the touch screen in the previous human-computer interaction. , using a new way to operate the phone, greatly improving the user's enjoyment of use.
