[0060] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0061] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0062] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0063] During the use of mobile terminals such as mobile phones, various environmental factors, including ambient humidity and objects in contact with the device, can affect the capacitance value of the antenna. Therefore, it is easy for the positional relationship between the target object and the mobile terminal to be inaccurate.

[0064] Based on this, in a first aspect, at least one embodiment of this disclosure provides a method for detecting positional relationships, please refer to the appendix. Figure 1 The diagram illustrates the process of the method, including steps S101 to S104.

[0065] This method is applied to a mobile terminal, which can, for example... Figure 2 and Figure 3 As shown, Figure 2 For mobile terminal 101, Figure 3 For a mobile terminal 101 with a protective case 102 installed. This method is applied to... Figure 2 When the mobile terminal 101 shown is used, it can be used to eliminate the problem of inaccurate detection of the positional relationship between the target object and the mobile terminal caused by environmental changes. This method is applied to... Figure 3 When the mobile terminal 101 shown is used, it can be used to eliminate problems such as inaccurate detection of the positional relationship between the target object and the mobile terminal caused by environmental changes, including the protective case 102. Figure 2 and Figure 3 In the mobile terminal 101, there are a first sensor 1011, a second sensor 1012 and an antenna 1013.

[0066] Positional relationship detection refers to detecting the positional relationship between a target object and a mobile terminal. For example, if the target object is a hand, then the detection would be the positional relationship between the hand and the mobile terminal. The positional relationship between the target object and the mobile terminal can include proximity and distance states. A proximity state could be the state where the hand is holding or touching the mobile terminal, while a distance state could be the state where the user is not touching the mobile terminal. Furthermore, the positional relationship between the target object and the mobile terminal can also include the positional relationship between the target object and a specific area of ​​the mobile terminal.

[0067] In step S101, attitude data collected by the first sensor is acquired.

[0068] The attitude data collected by the first sensor is used to determine the attitude of the mobile terminal. The first sensor may include a motion sensor, such as an accelerometer and / or a gyroscope. Correspondingly, the attitude data can be motion data, such as acceleration data.

[0069] When acquiring attitude data from the first sensor, the terminal can acquire it in real time or according to a preset method. Understandably, real-time acquisition involves a higher acquisition frequency, resulting in higher power consumption for the mobile terminal. Therefore, the acquisition frequency can be reduced without compromising the accuracy of the attitude data. The terminal can acquire attitude data periodically or at different frequencies during different time periods, i.e., according to a preset method. For example, a low frequency can be used from 10 PM to 7 AM the next morning, while a high frequency or real-time acquisition is used from 7 AM to 10 PM. Another example is when the mobile terminal is stationary for an extended period (the specific duration of which can be preset at the factory and / or set by the user as needed), at a low frequency.

[0070] In step S102, the attitude of the mobile terminal is determined based on the attitude data.

[0071] The posture of the mobile terminal can be its orientation and angle, or its static or dynamic state. At least one preset posture can be set in advance, and the posture of the mobile terminal includes these preset postures and other postures, with the other postures being a collective term for all postures other than the preset postures.

[0072] Optionally, when determining the attitude of the mobile terminal, a corresponding data range can be pre-set for each preset attitude, i.e., the range of attitude data corresponding to the preset attitude, such as the acceleration range. Then, in response to the time that the attitude data remains within the data range corresponding to the preset attitude, if it exceeds a preset time threshold, it is determined that the mobile terminal is in the preset attitude. In one example, the preset attitude is a stationary attitude, and its corresponding acceleration range is 0. Therefore, when the acceleration collected by the first sensor is 0, it can be determined that the mobile terminal is in a stationary state.

[0073] In step S103, in response to the mobile terminal's posture being a preset posture, the first capacitance value of the mobile terminal's antenna collected by the second sensor is obtained, and a compensation value is determined or updated based on the first capacitance value.

[0074] The preset posture can be selected when the capacitance value of the mobile terminal is less affected by environmental factors, such as when the mobile terminal is in a stationary or vertical posture. The vertical posture is defined as the angle between the plane of the mobile terminal's display screen and the vertical direction being less than a preset angle, for example, 30°. In the stationary state, the mobile terminal is in a fixed position, and the capacitance value is less affected by environmental factors. In the vertical posture, the mobile terminal is close to vertical, i.e., when the mobile terminal is placed inside clothing or a bag by the user, and the capacitance value is less affected by environmental factors. Therefore, the antenna capacitance value in these two states can be used as reference data to determine whether the antenna capacitance value is affected by environmental factors. Thus, compensation values ​​are determined or updated under these preset postures. If the compensation value has not yet been determined, it is determined for the first time under these preset postures; if the compensation value has already been determined, it is updated under these postures.

[0075] The second sensor can be a Specific Absorption Rate (SAR) sensor. This SAR sensor can acquire the capacitance value of the mobile terminal's antenna. When the mobile terminal is in one of the aforementioned preset postures, the capacitance value of the antenna acquired by the second sensor is recorded as a first capacitance value. This first capacitance value can be used to determine or update the compensation value. The mobile terminal saves the latest compensation value for later use in determining positional relationships.

[0076] Optionally, the compensation value can be determined or updated to the minimum value among the first capacitance values. The minimum value among the first capacitance values ​​can represent the capacitance value when the mobile terminal is in the most stable state, and therefore the influence of environmental factors is the least. Therefore, determining or updating the minimum value among the first capacitance values ​​as the compensation value can improve the accuracy of the compensation value, thereby improving the accuracy of detecting the positional relationship between the target object and the mobile terminal.

[0077] In step S104, the second capacitance value of the antenna of the mobile terminal collected by the second sensor is obtained, and the positional relationship between the target object and the mobile terminal is determined based on the second capacitance value and the compensation value.

[0078] This step can be performed when the mobile terminal is in a posture other than the preset posture. Specifically, when the mobile terminal is in the preset posture, it is used to determine the compensation value; when the mobile terminal is in a posture other than the preset posture, it is used to determine the positional relationship between the target object and the mobile terminal. Since the preset posture is defined based on the principle of minimizing the impact of environmental factors on the capacitance value of the mobile terminal's antenna, it can be assumed that when the mobile terminal is in the preset posture, the positional relationship between the target object and the mobile terminal is far away.

[0079] In this step, the capacitance value of the mobile terminal's antenna collected by the second sensor can be recorded as the second capacitance value. The mobile terminal can obtain the second capacitance value and determine the positional relationship between the target object and the mobile terminal based on the second capacitance value and the compensation value. When the target object is far away from the antenna, the antenna is in an unattended state, and the antenna capacitance value is small; when a target object approaches the antenna, the antenna capacitance value increases.

[0080] Optionally, firstly, the difference between the second capacitance value and the compensation value is determined as the actual capacitance value; nextly, in response to the actual capacitance value being greater than a preset capacitance threshold, the positional relationship between the target object and the mobile terminal is determined to be a proximity relationship. When determining the difference between the second capacitance value and the compensation value, the difference can be obtained by subtracting the compensation value from the second capacitance value and used as the actual capacitance value. Since the compensation value is the change in antenna capacitance value caused by external structures such as the protective casing of the mobile terminal, subtracting the compensation value from the second capacitance value can eliminate this change caused by external structures such as the protective casing. That is, the actual capacitance value is the change in capacitance caused by contact with the target object, thus eliminating the influence of external structures such as the protective casing on the detection of the positional relationship between the target object and the mobile terminal. When human tissue approaches the antenna, the antenna capacitance value increases. Therefore, a preset capacitance threshold can be used. When the increase in antenna capacitance value reaches this threshold, it is determined that human tissue is approaching, i.e., the positional relationship between the target object and the mobile terminal is determined to be a proximity relationship.

[0081] This disclosure acquires attitude data collected by a first sensor and determines the attitude of the mobile terminal based on the attitude data. Then, in response to the mobile terminal's attitude being a preset attitude, it acquires a first capacitance value of the mobile terminal's antenna collected by a second sensor, determines or updates a compensation value based on the first capacitance value, and finally acquires a second capacitance value of the mobile terminal's antenna collected by the second sensor. Based on the second capacitance value and the compensation value, it determines the positional relationship between the target object and the mobile terminal. Because the compensation value is determined or updated using the first capacitance value of the antenna collected by the second sensor under the preset attitude, and the second capacitance value and the compensation value are used when determining the positional relationship between the target object and the mobile terminal (i.e., the compensation value is used to compensate for the second capacitance value), the accuracy of detecting the positional relationship between the target object and the mobile terminal is improved.

[0082] In some embodiments of this disclosure, reference may be made to the appendix. Figure 2 and attached Figure 3 The mobile terminal 101 may have multiple antennas 1013, and each antenna 1013 corresponds to a different area of ​​the mobile terminal 101 and a different area of ​​the display screen. The area of ​​the mobile terminal 101 corresponding to the antenna 1013 can be recorded as the first corresponding area, and the area of ​​the display screen corresponding to the antenna 1013 can be recorded as the second corresponding area.

[0083] Based on this, the determination of the compensation value and the positional relationship between the target object and the mobile terminal can be targeted, i.e., determined separately for different antennas. Optionally, the first capacitance value of each antenna of the mobile terminal collected by the second sensor can be obtained, and the compensation value of the corresponding antenna can be determined or updated based on each first capacitance value; the second capacitance value of each antenna of the mobile terminal collected by the second sensor can be obtained, and the positional relationship between the target object and the first corresponding area of ​​the mobile terminal can be determined based on the second capacitance value of each antenna and the compensation value, wherein the first corresponding area is the area of ​​the mobile terminal corresponding to the antenna. The specific methods for determining the compensation value and the positional relationship between the target object and the first corresponding area can be the methods mentioned in the above embodiments, or other methods can be used, and this application does not limit them.

[0084] In this embodiment, by determining the compensation value and positional relationship for different antennas, the positional relationship between the target object and the mobile terminal can be determined more accurately. When the anti-mistouch function is activated according to the above positional relationship, it can be more targeted and reduce the area of ​​the display screen in the anti-mistouch state, thereby preventing accidental touches from causing misoperation and avoiding unnecessary impact on the display screen.

[0085] In some embodiments of this disclosure, when acquiring the second capacitance value of the antenna of the mobile terminal collected by the second sensor, and determining the positional relationship between the target object and the mobile terminal based on the second capacitance value and the compensation value, the compensation value can be updated to the minimum value among the second capacitance values ​​if the minimum value among the second capacitance values ​​is less than the compensation value. That is, when there is a value among the second capacitance values ​​that is less than the compensation value, the compensation value cannot represent the capacitance value when the target object has the least impact on the antenna capacitance value. Therefore, the compensation value cannot accurately exclude capacitance value changes caused by environmental changes or external structures such as mobile phone cases. Therefore, it is necessary to further update the compensation value, i.e., update the minimum value among the second capacitance values ​​to the compensation value, thereby improving the accuracy of the compensation value and, consequently, improving the accuracy of the positional relationship between the target object and the mobile terminal determined based on this compensation value.

[0086] In some embodiments of this disclosure, after determining the positional relationship between the target object and the mobile terminal, in response to the fact that the positional relationship between the target object and the mobile terminal is close, the second corresponding area of ​​the mobile terminal's display screen can be determined to be in an anti-accidental touch state, wherein the second corresponding area is the area of ​​the display screen corresponding to the antenna to which the second capacitance value belongs.

[0087] In this embodiment, by using compensation values ​​to eliminate the influence of environmental changes and external structures such as protective shells on the antenna capacitance value, the influence of the target object on the antenna capacitance value is accurately determined. After determining the positional relationship between the target object and the mobile terminal, the anti-mistouch function of the display screen can be accurately activated or deactivated. Moreover, the anti-mistouch area can be accurately determined based on the position of the antenna, thus improving the accuracy of the anti-mistouch function. In other words, it can accurately activate the anti-mistouch function to avoid accidental operation and avoid affecting the use of the display screen.
