【Detailed ways】

In order to better understand the technical solutions of the present application, the following describes the embodiments of the present application in detail with reference to the accompanying drawings.

It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

It should be noted that the pressed state of the button includes two possible situations: 1. The button is in a pressed state; 2. The button is in a released state.

The external wireless keyboard receives the user's operation, and sends the user's operation information to the electronic device, so that the electronic device performs corresponding operations according to the user's operation information. The following examples illustrate related technologies. The user presses the key A of the keyboard, and the keyboard detects that the key A is in a pressed state, and reports the information of the key A (that is, the information transmitted for the first time in Figure 1(a)) to the electronic device. Within a period of time, the user presses the key K of the keyboard again. The keyboard detects that the key A and the key K are in the pressed state, and reports the information of the key A and the key K to the electronic device (ie, the second key in Figure 1(a)). Information transmitted for the second time).

In the embodiment of the present application, both the keyboard and the electronic device store a key list. The button list may include one or more buttons, or it may not include any buttons. In the case where the key list does not include any keys, the key list is called an empty list. Please refer to Figure 2-1, which shows a key list including one button; refer to Figure 2-2, which shows a key list including two keys; refer to Figure 2-3, which shows a Kind of empty list.

It is assumed that the initial state of the key list stored in the keyboard and the electronic device is an empty list. The user presses the key A of the keyboard, and the keyboard detects that the key A is in the pressed state, the keyboard updates its own stored key list. After the update, the key list stored in the keyboard includes key A. The keyboard compares the currently stored key list with the previously stored key list. The key list is compared, the change information is key A, and the keyboard reports the information of key A to the electronic device (that is, the information transmitted for the first time in Figure 1(b)). During a period of time when the button A is in the pressed state, the user presses the button K of the keyboard again, and the keyboard detects that the button A and the button K are in the pressed state, and the keyboard updates its own stored button list. The key list includes key A and key K. The keyboard compares the currently stored key list with the previously stored key list. The change information is key K. The keyboard reports the information of key K to the electronic device (ie the second in Figure 1(b)). Information transmitted for the second time).

Through the above analysis, it can be known that in the related art, the keyboard reports all the information of the pressed key to the electronic device, and the amount of data transmitted between the keyboard and the electronic device is relatively large, which causes the electronic device to respond to user operations more time-consuming. Long and poor user experience. In the embodiment of the present application, the keyboard reports to the electronic device information about the keys whose state has changed (that is, from the pressed state to the released state, or from the released state to the pressed state). The amount of data transmitted between electronic devices is reduced, and the transmission speed is faster, thereby improving the response speed of the electronic devices.

An embodiment of the present application provides a control system, which includes a keyboard and electronic equipment.

The keyboard can be a touch keyboard or a keyboard with physical keys. The electronic device can be a mobile phone, a tablet computer, a notebook computer, etc.

The keyboard is wirelessly connected to the electronic device, and jointly executes the control method provided in the embodiment of the present application.

Please refer to FIG. 3, which shows a flowchart of a method for controlling the keyboard and an electronic device to execute jointly provided by the first embodiment of the application. The controlling method includes the following steps:

Step S301: The keyboard detects the pressed state of the key, and determines the current key list based on the pressed state of the key, and uses the obtained key list as the first key list.

If it is detected in step S301 that two buttons (for example, button A and button B) are in a pressed state, it is determined that the current button list includes two buttons (button A and button B).

If it is detected in step S301 that no keys are in a pressed state, that is, all keys are in a released state, it is determined that the current key list is an empty list.

For the touch keyboard, detecting the pressed state of the key in step S301 may specifically include: obtaining the position information of the touch point, the touch point is located in the touch area of the touch keyboard; and determining the pressed state according to the position information of the touch point Button.

Please refer to FIG. 4, which shows a touch keyboard 10 provided by an embodiment of the application, and the touch keyboard 10 includes a touch area 100.

The user touches the touch area of the touch keyboard with a finger or other object, and the point in contact with the touch keyboard is the touch point.

As an optional method, the position information of the touch point includes the coordinates of the touch point, and determining the button in the pressed state according to the position information of the touch point includes: determining whether the coordinates of the touch point are within the coordinate range corresponding to the first button ; If the coordinates of the touch point are within the coordinate range corresponding to the first key, it is determined that the first key is in the pressed state, and the first key is any key in the touch keyboard.

In order to determine the coordinates of the touch point, a two-dimensional rectangular coordinate system is established on the plane where the keyboard is located. Figures 5-1 to 5-4 show optional ways to establish a coordinate system. It should be noted that FIGS. 5-1 to 5-4 are only examples, and the method of establishing a coordinate system provided by the embodiment of the present application is not limited to these specific situations.

Each key of the keyboard corresponds to a certain coordinate range. When the coordinates of the touch point fall within the coordinate range corresponding to a certain key, it is considered that the user has pressed the key.

For example, suppose that in the coordinate system shown in Figure 5-1, the coordinate range corresponding to button A is: the range of abscissa is (317, 507), and the range of ordinate is (1057, 1319); button S corresponds to The coordinate range is: the range of the abscissa is (533, 965), and the range of the ordinate is (1057, 1319).

If the coordinates of the touch point are (500, 1300), since the abscissa of the touch point is in the range (317, 507) and the ordinate is in the range (1057, 1319), it means that the touch point is located at the corresponding button A Within the range of coordinates, it can be known that A is in a pressed state.

If the coordinates of the touch point are (600, 1300), since the abscissa of the touch point is in the range (533, 965) and the ordinate is in the range (1057, 1319), it means that the touch point is located at the corresponding button S Within the coordinate range, it can be known that the button S is in a pressed state.

If the coordinates of the touch point are (1000, 1300), since the abscissa of the touch point is not in the range of (317, 507), it means that the touch point is not in the coordinate range corresponding to button A, so you can know the corresponding touch point The button is not button A; since the abscissa of the touch point is not within the range of (533, 965), it means that the touch point is not in the coordinate range corresponding to button S, so it can be known that the button corresponding to this touch point is not button S either .

Step S302: After the preset time interval, the keyboard detects the pressed state of the key, and determines the current key list based on the pressed state of the key, and uses the obtained key list as the second key list.

The preset time interval is a relatively short time, which can be set according to actual requirements. For example, the preset time interval is set to 0.1 second, 0.2 second, or 0.5 second.

Step S303: The keyboard compares the second key list with the first key list to obtain first change information.

The first change information includes keys that are different from the second key list and the first key list, for example, keys included in the first key list and not included in the second key list, or included in the second key list and Keys not included in the first key list. For example, suppose that only the key "Ctrl" is included in the first key list, and the second key list includes two keys: the key "Ctrl" and the key "V". Comparing the second key list with the first key list, we can see that The different key in the two key lists is the key "V". As another example, suppose that the first button list includes the button "Ctrl" and the button "C", and the second button list includes only one button: the button "Ctrl". Compare the second button list with the first button list. The different key in these two key lists is key "C".

If the first button list includes at least one button and the second button list does not include any buttons, the first change information includes all the buttons in the first button list. For example, suppose that the first key list includes the key "Ctrl" and the key "C", and the second key list does not include any keys. Comparing the second key list with the first key list, you can see that the two key lists are different The keys are all the keys in the first key list, namely key "Ctrl" and key "C".

Step S304: The keyboard sends the first change information to the electronic device. The electronic device is wirelessly connected to the keyboard.

Step S305: The electronic device receives the first change information sent by the keyboard.

Step S306: The electronic device updates its stored button list according to the first change information.

Step S307: The electronic device performs a corresponding operation according to the updated key list.

A key list is also stored and maintained in the electronic device.

As mentioned above, the first change information includes the different keys in the second key list and the first key list. For the convenience of description, the different keys in the second key list and the first key list are called the second keys. A change message includes the second button.

As an optional implementation manner, step S306 may specifically include: the electronic device determines whether the second key is included in the key list stored in the electronic device; if the second key is not included in the key list stored in the electronic device, then the stored key list Add a second key in the key list; if the second key is included in the key list stored in the self, delete the second key in the key list stored in the self.

For example, if it is determined in step S303 that the different key in the second key list and the first key list is the key "V" (the first change information is the key "V"), then the first change information is sent to the electronic device, and the electronic The device itself stores and maintains a key list. Assuming that the key “Ctrl” is stored in the key list, after receiving the information of the key “V”, the electronic device judges whether the key “V” is included in the stored key list. The judgment result indicates If the key "V" is not included in the key list stored in the electronic device, the key "V" is added to the key list stored in the electronic device.

For another example, the electronic device itself stores and maintains a key list. The key list stores the key "Ctrl" and the key "V". It is assumed that the keys in the second key list and the first key list are determined in step S303. Press the "Ctrl" and "V" keys (the "Ctrl" and "V" keys are the first change information), the first change information is sent to the electronic device, and the electronic device receives the "Ctrl" and "V" keys After the information, it is judged whether the stored key list includes the key "Ctrl" and the key "V". The judgment result indicates that the key list stored by the electronic device includes the key "Ctrl" and the key "V", and the electronic device deletes the stored keys The key "Ctrl" and key "V" in the list.

In step S307, a corresponding operation is performed according to the updated key list. For example, assuming that the keys stored in the updated key list of the electronic device are the key "Ctrl" and the key "V", the electronic device performs the "paste" operation.

It should be noted that the keyboard only needs to send information about different keys included in the first key list and the second key list to the electronic device. As for the key is included in the first key list and not included in the second key list (The deleted key) is still included in the second key list and not included in the first key list (added key), and this information does not need to be sent to the electronic device. After the electronic device receives the information of a certain key, for example, receives the information of the second key, it determines whether the second key is included in the key list stored by the electronic device. If the second key is included in the key list stored by the electronic device, then It means that the second button has been pressed before, then this operation is to release the second button, and the electronic device deletes the second button in the button list stored by itself; if the button list stored by the electronic device does not include the second button Press the button, it means that the second button was in the released state before, then the operation this time is to press the second button, and the electronic device adds the second button to its stored button list.

As an optional method, after sending the first change information to the electronic device, the keyboard also performs the following steps: detecting the pressed state of the key, and determining the current key list based on the pressed state of the key, and the obtained key The list is used as the third key list; the third key list is compared with the second key list to obtain the second change information; the second change information is sent to the electronic device, so that the electronic device can store the key list of itself according to the second change information Update.

Assuming that after the keyboard sends the first change information to the electronic device, the keyboard detects that there is no key currently in a pressed state, it is determined that the current key list does not include any keys, that is, the third key list is an empty list. Assume that the second key list includes two keys, namely the key "Ctrl" and the key "V". The third key list is compared with the second key list, and the obtained second change information includes all keys in the second key list. The keyboard sends the key "Ctrl" and the key "V" to the electronic device, so that the electronic device updates its stored key list.

It can be understood that after the keyboard sends the second change information to the electronic device, it can continue to detect the state of the key, and determine the current key list based on the pressed state of the key, and compare the current key list with the last key list to obtain the key list The change information of the button list is sent to the electronic device, so that the electronic device updates its stored button list according to the change information of the button list, and performs corresponding operations according to the updated button list.

As an optional way, the coordinate & key lookup table can be stored in the keyboard. The query table stores the coordinate range corresponding to each button. Establish the coordinate system as shown in Figure 5-1. The area corresponding to each button is a rectangle. The coordinates of the upper left corner of the rectangle are referred to as the upper left coordinates of the button, and the coordinates of the lower right corner of the matrix are referred to as the The bottom right coordinates of the button, please refer to Figure 6, the top left coordinates of the button A are (317, 1057), the bottom right coordinates are (507, 1319); the top left coordinates of the button S are (533, 1057), the bottom right coordinates are ( 965, 1319). That is, the coordinate range corresponding to button A is: the range of abscissa is (317, 507), and the range of ordinate is (1057, 1319); the coordinate range corresponding to button S is: the range of abscissa is (533, 965) ), and the range of the ordinate is (1057, 1319).

If the touch coordinates (x, y) of a certain touch point are within the coordinate range corresponding to a certain key, it means that the touch point corresponds to the key and the key is in a pressed state. E.g:

If the coordinates of the touch point are (500, 1300), since the abscissa of the touch point is in the range (317, 507) and the ordinate is in the range (1057, 1319), it means that the touch point is located at the corresponding button A Within the coordinate range, the button corresponding to this touch point is button A, which is in a pressed state.

If the coordinates of the touch point are (600, 1300), since the abscissa of the touch point is in the range (533, 965) and the ordinate is in the range (1057, 1319), it means that the touch point is located at the corresponding button S Within the coordinate range, the button corresponding to this touch point is button S, so it can be known that button S is in a pressed state.

In the second embodiment of the present application, it is assumed that an empty list is stored in both the keyboard and the electronic device. Please refer to Figure 7. The user presses the key A of the keyboard, and the keyboard detects that the key A is in a pressed state, the keyboard updates its stored key list. After the update, the key list includes a key: key A, the keyboard will compare the current key list with The last time the key-press list is compared, the change information is key A. The keyboard transmits the information of button A to the electronic device. The electronic device determines whether the stored button list includes button A. Since the button list currently stored by the electronic device is an empty list, the current button list stored by the electronic device does not include button A , The electronic device updates the button list (that is, adding button A to its own stored button list), and the updated button list stored by the electronic device includes button A. Assume that the user does not release the button A immediately after pressing the button, but keeps the button A in a pressed state for a period of time and presses the button K. When the keyboard detects that button A and button K are in a pressed state, the keyboard updates the stored button list. After the update, the button list includes two buttons: button A and button K. The keyboard compares the current button list with the last button list. Get the change information as the button K. The keyboard transmits the information of the button K to the electronic device, and the electronic device updates its stored button list (the electronic device determines whether the currently stored button list includes the button K. Since the judgment result indicates that the button K is not included, the button K is added The key list stored in the electronic device itself after the update includes key A and key K. After a period of time, the user releases button A and button K at the same time. The keyboard detects the pressed state of the key. The detection result shows that no key is in the pressed state. The keyboard updates its own stored key list. After the update, the key list is empty. The keyboard compares the current key list with the last key list to get the change The information is button A and button K. The keyboard transmits the information of button A and button K to the electronic device, and the electronic device updates its stored button list (the electronic device determines whether the currently stored button list includes button A and button K, because the judgment result indicates that it includes button A and Press the button K, so the button A and the button K are deleted from the button list stored in itself), the button list stored in the electronic device itself is an empty list after the update.

In an embodiment of the present application, the coordinate & key lookup table can be pre-stored in the touch keyboard. The user touches a certain position on the touch area of the touch keyboard, and the touch IC (Integrated Circuit, integrated circuit) determines the touch coordinates. By searching the key corresponding to the touch coordinate in the coordinate & key query table, the conversion from position to key is performed, that is, the key corresponding to the touch position is determined. According to the determined keys, the current key list is obtained, the current key list is compared with the last key list, and if there is a change, the changed key is reported to the electronic device connected to the touch keyboard.

Compared with the method in the related art, using the method provided in the embodiment of the application, the amount of data reported by the keyboard to the electronic device is smaller, and it has the advantages of small communication volume and real-time reporting. It can be applied to wireless channels, such as Bluetooth keyboard, 2.4 The G keyboard can reduce the time consumption of the electronic device in responding to the user's touch operation, improve the response speed of the electronic device, and can improve the user experience.
