[0025] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0026] First, a brief introduction to the terms involved in the embodiments of this application is given:

[0027] SAR (Specific Absorption Rate) sensor: A SAR sensor is a built-in sensor in a terminal that detects the relative position (primarily distance) between the terminal and the human body. When the terminal is close to the human body or head, the terminal's antenna transmit power is reduced to reduce the amount of energy radiated to the human body. In this application, the terminal's housing information can affect the SAR sensor's determination of the relative position between the terminal and the ground. Therefore, the SAR sensor can be used to determine the terminal's external protective accessories.

[0028] Detection parameter: refers to information related to the SAR signal obtained by the SAR sensor. In one embodiment, the detection parameter may include at least one of the current, voltage, charge, and capacitance of the SAR signal. It is worth noting that this application does not limit the type of detection parameter. The detection parameter is only used to represent changes in the SAR signal. Based on basic physics, it can be obtained that capacitance can be converted into other detection parameters such as current, voltage, charge, etc.

[0029] Figure 1 1 is a structural block diagram of a computer system according to an exemplary embodiment of the present application. The computer system 100 may include a SAR sensor 101 , a central processing unit 102 , and a memory 103 .

[0030] The SAR sensor 101 is provided in the terminal and is used to detect the relative state between the human body and the terminal. Upon receiving the SAR signal, the SAR sensor 101 converts the SAR signal into detection parameter data and sends the detection parameter data to the central processor 102.

[0031] The central processing unit 102 is provided in the terminal and is used to process various data. Based on the detection parameter data received by the central processing unit 102 from the SAR sensor 101, the central processing unit 102 sends a call instruction to the memory 103, which is used to call the external protection accessory data and operating parameter data stored in the memory.

[0032] Memory 103 is provided within the terminal and is used to store various data. Based on the mapping relationships between detection parameter data and external protection accessory data, and the mapping relationships between external protection accessory data and operating parameter data stored on memory 103, memory 103 receives call instructions sent by central processing unit 102 and returns the external protection accessory data and operating parameter data to central processing unit 102.

[0033] In one embodiment, the SAR sensor 101, the central processing unit 102 and the memory 103 are provided on the terminal in the form of an integrated circuit, and the connection between them includes: Figure 1 The connection method shown is Figure 1 This is just an example connection.

[0034] The device types of the above-mentioned terminals may include: at least one of: a smartphone, a tablet computer, an e-book reader, an MP3 player (Moving Picture Experts Group Audio Layer III, Moving Picture Experts Group Audio Layer 3), an MP4 player (Moving Picture Experts Group Audio Layer IV, Moving Picture Experts Group Audio Layer 4), a laptop computer, and a desktop computer. Those skilled in the art will appreciate that the number of the above-mentioned terminals may be more or less. For example, the above-mentioned terminal may be only one, or the above-mentioned terminals may be dozens, hundreds, or even more. The embodiments of the present application do not limit the number and device types of the terminals.

[0035] To determine whether the terminal is equipped with external protection accessories, perform the following steps: Figure 2 The method shown is applied in a terminal provided with a SAR sensor. Figure 2 This is a flow chart of an information determination method provided by an exemplary embodiment of the present application. Figure 2 As shown, the method may include:

[0036] Step 201, obtaining a SAR signal through a SAR sensor;

[0037] The terminal obtains SAR signals through the SAR sensor. Based on the electromagnetic waves returned by the terminal to the ground, the returned electromagnetic waves are input into the SAR sensor. The above-mentioned returned electromagnetic waves are SAR signals.

[0038] Step 202, calculating a detection parameter value of the SAR sensor according to the SAR signal;

[0039] The detection parameters may include at least one of capacitance, voltage, current and charge. Based on basic physics knowledge, capacitance, voltage, current and charge may also be converted into other physical parameters. This application does not limit the type of physical parameters. The following uses the detection parameter as an example of capacitance to ground.

[0040] In one embodiment, the terminal calculates the ground capacitance value of the SAR sensor according to the SAR signal.

[0041] In one embodiment, the terminal may calculate the ground capacitance value of the SAR sensor according to the SAR signal, including the following two steps:

[0042] First, calculate the ground distance information of the terminal based on the SAR signal;

[0043] Based on basic physics knowledge, the terminal-to-ground distance information can be obtained by performing signal analysis on the above-mentioned SAR signal.

[0044] Optionally, the terminal further calculates the dielectric constant of the terminal to the ground according to the SAR signal.

[0045] Based on basic physics knowledge, the dielectric constant of the terminal to the ground can be obtained by performing signal analysis on the above SAR signal.

[0046] Second, the terminal-to-ground distance information is converted into the ground capacitance of the SAR sensor.

[0047] Basic physics shows that the distance between the terminal and the ground affects the change in the SAR sensor's capacitance to the ground. The smaller the distance between the terminal and the ground, the greater the SAR sensor's capacitance to the ground, and the larger the distance between the terminal and the ground, the smaller the SAR sensor's capacitance to the ground. In other words, the SAR sensor's capacitance to the ground is inversely proportional to the distance between the terminal and the ground.

[0048] Optionally, the terminal-to-ground distance information is converted into the ground capacitance of the SAR sensor.

[0049] The above discussion has completed the relationship between the terminal-to-ground distance and the SAR sensor's capacitance to ground. The following discussion will focus on the relationship between the dielectric constant between the terminal and ground and the SAR sensor's capacitance to ground.

[0050] Basic physics shows that the dielectric constant between the terminal and ground affects the change in the SAR sensor's capacitance to ground. The larger the dielectric constant between the terminal and ground, the greater the SAR sensor's capacitance to ground. The smaller the dielectric constant between the terminal and ground, the smaller the SAR sensor's capacitance to ground. In other words, the SAR sensor's capacitance to ground is directly proportional to the dielectric constant between the terminal and ground.

[0051] Optionally, the terminal-to-ground distance information and the terminal's dielectric constant are converted into a SAR sensor's capacitance to the ground.

[0052] Step 203 : In response to the detection parameter value of the SAR sensor being within a preset value range, it is determined that an external protection accessory is provided on the terminal.

[0053] The preset value range includes a value range preset by the terminal, and it is determined that the terminal is provided with an external protection accessory based on a corresponding relationship between the detection parameter value and the value range.

[0054] In one embodiment, it is determined that an external protection accessory is provided on the terminal according to the ground capacitance value of the SAR sensor.

[0055] In one embodiment, the terminal determines that an external protection accessory is provided on the terminal according to the detection parameter value of the SAR sensor being within a preset value range.

[0056] In one embodiment, in response to the detection parameter value of the SAR sensor belonging to the no-accessory value range, it is determined that the terminal is not provided with an external protection accessory; illustratively, the no-accessory value range is 1000±100.

[0057] In one embodiment, the preset value range includes n value subranges, where n is a positive integer not less than 1; in response to the detection parameter value of the SAR sensor belonging to the i-th value subrange, it is determined that the terminal is equipped with an external protective accessory of the i-th category, where i is not greater than n and i is a positive integer not less than 1.

[0058] In one embodiment, in response to the detection parameter value of the SAR sensor belonging to the i-th value sub-range, illustratively, the i-th value sub-range is 1200±30, the terminal determines that the terminal is provided with an external protection accessory.

[0059] In an optional embodiment, in response to a detection parameter value of the SAR sensor falling within the i-th value sub-range and lasting for a duration reaching a threshold, it is determined that the terminal is equipped with an external protective accessory. For example, if the detection parameter value of the SAR sensor falls within the range of 1200±30 and lasts for 1 hour, it is determined that the terminal is equipped with an external protective accessory.

[0060] In an optional embodiment, n can be 2, that is, the preset value range can include a first value sub-range and a second value sub-range. In response to the detection parameter value of the SAR sensor falling within the first value sub-range (i.e., i can be 1), it is determined that the terminal is equipped with a first category of external protection accessories; in response to the detection parameter value of the SAR sensor falling within the second value sub-range (i.e., i can be 2), it is determined that the terminal is equipped with a second category of external protection accessories. The first and second value sub-ranges are merely illustrative. In possible implementations, n can also be other positive integers such as 3 or 4. In other words, the preset value range can also be set to include other value sub-ranges such as a third value sub-range and a fourth value sub-range, and the value sub-ranges match the categories of external protection accessories.

[0061] Illustratively, in response to the detection parameter value of the SAR sensor belonging to the first value sub-range, the first value sub-range is 1200±30, and it is determined that the terminal is provided with external protection accessories of the first category; in response to the detection parameter value of the SAR sensor belonging to the second value sub-range, the second value sub-range is 1500±50, and it is determined that the terminal is provided with external protection accessories of the second category.

[0062] Illustratively, in response to the detection parameter value of the SAR sensor belonging to the first value sub-range, the first value sub-range is 1200±30 and the duration is not less than one hour, it is determined that the terminal is equipped with a first category of external protection accessories; in response to the detection parameter value of the SAR sensor belonging to the second value sub-range, the second value sub-range is 1500±50 and the duration is not less than one hour, it is determined that the terminal is equipped with a second category of external protection accessories.

[0063] Optionally, the external protective accessories may include at least one of a protective cover, a protective film, and an earphone jack plug.

[0064] Taking a mobile phone as an example, the above-mentioned external protective accessories may include at least one of a mobile phone case, a mobile phone film, and an earphone jack plug. Different categories of external protective accessories may include at least one of external protective accessories of different sizes, external protective accessories of different thicknesses, external protective accessories of different colors, and external protective accessories of different materials. In one embodiment, the material of the first category of external protective accessories may be metal; in one embodiment, the material of the second category of external protective accessories may be silicone. In one embodiment, the material of the third category of external protective accessories may be glass (for example, such as tempered glass). In one embodiment, the material of the fourth category of external protective accessories may be ceramic.

[0065] In summary, the SAR sensor acquires a SAR signal, then calculates a SAR sensor detection parameter value based on the SAR signal. Finally, in response to the SAR sensor detection parameter value being within a preset value range, the terminal determines that an external protective case is installed. This method is implemented using the terminal's built-in sensors, eliminating the need for additional circuitry. Not only does it detect external protective accessories while consuming minimal resources, but the detected external protective accessories are not limited to specific categories.

[0066] based on Figure 2 In the optional embodiment shown, step 204 may be further included after step 203 .

[0067] Step 204 : In response to the terminal being provided with an external protection accessory, configuring operating parameters adapted to the external protection accessory.

[0068] The operating parameters may include at least one of antenna parameters, display parameters and touch parameters.

[0069] In one embodiment, the antenna parameters can be used to adjust the antenna's transmission power. Schematically, when the terminal determines that there are no external protective accessories on the current terminal surface, the terminal lowers the antenna's transmission power; when the terminal determines that there is a metal shell on the current terminal surface, the terminal increases the antenna's transmission power.

[0070] In one embodiment, the display parameters can be used to adjust the display screen state of the terminal. For example, when the terminal determines that there are no external protective accessories on the current terminal surface, the terminal controls the display screen to display a first interface; when the terminal determines that there is a metal casing on the current terminal surface, the terminal controls the display screen to display a second interface.

[0071] In one embodiment, the touch parameters refer to parameters set in the terminal regarding touch operations, wherein the touch parameters may include at least one of a touch threshold, a touch duration, and a touch count.

[0072] In one embodiment, in response to the terminal being equipped with an external protection accessory of category i, the configuration is configured to adapt to the i-th operating parameter of the external protection accessory of category i. Exemplarily, in response to the terminal being equipped with an external protection accessory of category one, the configuration is configured to adapt to the antenna parameters and touch parameters of the external protection accessory of category one.

[0073] In one embodiment, in response to the terminal being provided with an external protective accessory of the i-th category, an i-th touch parameter adapted to the external protective accessory of the i-th category is configured.

[0074] In one embodiment, the above method for setting touch parameters may include at least the following two cases:

[0075] First, in response to the terminal being provided with a first category of external protection accessories, configuring a first touch parameter adapted to the first category of external protection accessories;

[0076] Illustratively, the terminal determines that the terminal is provided with a metal external protection accessory, and configures a touch threshold adapted to the metal external protection accessory to be 1000.

[0077] Second, in response to the terminal being provided with an external protective accessory of a second category, a second touch parameter adapted to the external protective accessory of the second category is configured.

[0078] Illustratively, the terminal determines that the terminal is provided with a silicone external protection accessory, and configures a touch threshold adapted to the silicone external protection accessory to be 1200.

[0079] It's worth noting that the first touch parameters corresponding to the first category of external protective accessories and the second touch parameters corresponding to the second category of external protective accessories are for illustrative purposes only. In an exemplary application scenario, multiple categories of external protective accessories may correspond to a set of touch parameters. For example, when the terminal determines that the current external protective accessory is a Class A external protective accessory or a Class B external protective accessory, the first touch parameters are configured.

[0080] In one embodiment, the touch threshold is the threshold that determines whether the touch screen reports a touch event to the processor when it detects a signal change. For example, the touch screen reports a touch event to the processor when the peak value of the signal generated by the user's touch operation is no less than the touch threshold. Alternatively, the touch screen reports a touch event to the processor when the peak value of the signal generated by the user's touch operation is no less than the touch threshold and the duration exceeds a preset touch duration.

[0081] That is, the touch threshold can be used to set the touch sensitivity of the touch screen. For example, when the touch threshold is small, in response to the user lightly touching the touch screen of the terminal, the touch screen reports the touch event to the processor, and the corresponding touch sensitivity of the touch screen is high; when the touch threshold is large, in response to the user lightly touching the touch screen of the terminal, the touch screen cannot report the touch event to the processor, and the corresponding touch sensitivity of the touch screen is low.

[0082] In one embodiment, the touch threshold is stored inside the terminal; in one embodiment, the touch threshold can be implemented as at least one of the maximum capacitance, maximum voltage, maximum current and maximum charge of the signal generated by the user operation. This application does not limit the above physical parameter types.

[0083] Indicative, Figure 3 The corresponding relationship between the external protection accessories and the touch threshold provided by an exemplary embodiment of the present application is shown.

[0084] When the terminal is not equipped with external protection accessories, the touch screen touch threshold is S1; when the terminal is equipped with external protection accessory 1, the touch screen touch threshold is S2; when the terminal is equipped with external protection accessory 2, the touch screen touch threshold is S3;

[0085] Figure 3 The first line 301 indicates the user's touch operation process when the terminal is not equipped with external protective accessories. When the peak value of the signal generated by the user's touch operation is not less than the touch screen touch threshold S1, the touch screen reports the touch event to the processor.

[0086] Figure 3 The second line 302 indicates the user's touch operation process when the terminal is equipped with the external protection accessory 1. When the peak value of the signal generated by the user's touch operation is not less than the touch screen touch threshold S2, the touch screen reports the touch event to the processor.

[0087] Figure 3 The third line 303 indicates the user's touch operation process when the terminal is equipped with the external protection accessory 2. When the peak value of the signal generated by the user's touch operation is not less than the touch screen touch threshold S3, the touch screen reports the touch event to the processor.

[0088] In summary, in response to the terminal being equipped with an external protection accessory, the operating parameters adapted to the external protection accessory are configured. The above solution enables the terminal's operating parameters to adapt to different scenarios, that is, to configure corresponding operating parameters in different scenarios, further optimizing the user's operating experience.

[0099] In one embodiment, the determining module 403 is further configured to determine that the terminal is equipped with an external protective accessory of the i-th category in response to the detection parameter value of the SAR sensor belonging to the i-th value sub-range and the duration thereof reaching a threshold.

In addition, the information determination device provided in the above embodiment and the information determination method embodiment are based on the same concept. The specific implementation process is detailed in the method embodiment and will not be repeated here.

[0106] In summary, the device provided in this embodiment acquires SAR signals via a SAR sensor. The terminal then calculates the SAR sensor's detection parameter value based on the SAR signal. Finally, in response to the SAR sensor's detection parameter value being within a preset value range, the terminal determines that an external protective case is installed. This device is implemented using the terminal's built-in sensors, eliminating the need for additional circuitry. This device not only detects external protective accessories while consuming minimal resources, but also detects accessories that are not limited to specific categories. This device enables the terminal to obtain information about external protective accessories, allowing the terminal to adjust operating parameters based on this information. This allows the terminal to configure corresponding operating parameters for different scenarios, further optimizing the user experience.
