First embodiment
Referring to fig. 1, an embodiment of the present invention provides a left-right hand identification method applied to a mobile terminal, including steps 101 to 103, which are described in detail below.
Step 101: after the fact that the mobile terminal is held is detected, a first capacitance change value of a first sensor on a preset area on the left side of the mobile terminal is obtained.
In the embodiment of the invention, the preset area on the left side of the mobile terminal is specifically a lower area on the left side of a screen when the screen of the mobile terminal faces upwards. When the user holds the mobile terminal with the left hand, the palm of the left hand is generally located in the left preset area, and when the user holds the mobile terminal with the right hand, the fingers of the right hand are generally located in the left preset area.
The left preset area is provided with a first sensor, the first sensor is a capacitive metal sensor based on capacitance change, and the first sensor relates to a metal covering layer which can be equivalent to a capacitance plate. In practical applications, the metal covering layer is, for example, a housing metal of a mobile terminal or an antenna metal, and the invention is not limited thereto.
Specifically, a first capacitance change value C of the first sensorFComprises the following steps: cF＝0 rA/d。
Wherein,0is a dielectric constant of air and is,rthe relative dielectric constant of the metal coating, A is the effective contact area between the hand and the metal coating, and d is the thickness of the metal coating.
When a user touches the first sensor with either the left or right hand, the effective area of the corresponding metal overlay is typically affected, thereby affecting the capacitance value of the first sensor. What is obtained in step 101 is the capacitance change value of the first sensor after the user holds the mobile terminal with one hand.
Step 102: and acquiring a second capacitance change value of a second sensor in a preset area on the right side of the mobile terminal.
In the embodiment of the invention, the preset area on the right side of the mobile terminal is specifically a lower area on the right side of a screen when the screen of the mobile terminal faces upwards. When the user holds the mobile terminal with the right hand, the palm of the right hand is generally located in the left preset area, and when the user holds the mobile terminal with the left hand, the fingers of the left hand are generally located in the right preset area.
The second sensor is also a capacitive metal sensor based on capacitance change, and relates to a metal covering layer, the implementation principle is the same as that of the first sensor, and the calculation of the capacitance change value is the same as that of the first sensor, so that the description is omitted.
In order to ensure the accuracy of the right-hand and left-hand recognition according to the present invention, the metal coating layer of the first sensor is the same in material, thickness, and the like as compared with the metal coating layer of the second sensor.
When a user touches the second sensor with his or her left or right hand, the effective area of the corresponding metal overlay is typically affected, thereby affecting the capacitance value of the second sensor. What is obtained in step 102 is the capacitance change value of the second sensor after the user holds the mobile terminal with one hand.
Step 103: and identifying whether the hand is held by the left hand or the right hand according to the first capacitance change value and the second capacitance change value.
Specifically, when a user holds the mobile terminal with one hand, the palm is usually on one side of the mobile terminal and the fingers are on the other side of the mobile terminal. If the mobile terminal is held by the left hand, the palm of the left hand is generally located in a left preset area of the mobile terminal, and meanwhile, the fingers of the left hand are located in a right preset area of the mobile terminal; if the mobile terminal is held by the right hand, the palm of the right hand is generally located in the right preset area of the mobile terminal, and the fingers of the right hand are located in the left preset area of the mobile terminal.
When a user holds the mobile terminal by a single hand, the contact areas of the palm and the fingers with the metal covering layers on the two sides of the mobile terminal are different, generally, the contact area of the palm is large, the contact area of the fingers is small, and therefore the influences on the capacitance values of the sensors on the two sides are different. Generally, the larger the contact area with the metal cover layer, the greater the influence on the capacitance value of the corresponding sensor.
Thus, from the first capacitance change value and the second capacitance change value, it is possible to recognize whether the hand is held by the left hand or held by the right hand.
Specifically, when the first capacitance change value is larger than the second capacitance change value, it is indicated that the contact area between the hand and the metal covering layer of the first sensor is larger than that of the second sensor, and it can be recognized that the hand is held by the left hand; when the first capacitance change value is smaller than the second capacitance change value, it is indicated that the contact area between the hand and the metal covering layer of the second sensor is larger than that of the first sensor, and the hand is held by the right hand.
Therefore, after the left-hand holding or the right-hand holding is recognized, the corresponding single-hand mode of the mobile terminal can be started, and under the condition that the first sensor or the second sensor utilizes the antenna metal, the left antenna or the right antenna can be adjusted and used, so that the antenna performance is improved.
According to the left-hand and right-hand identification method, after the fact that the mobile terminal is held is detected, the first capacitance change value of the first sensor on the left preset area of the mobile terminal is obtained, the second capacitance change value of the second sensor on the right preset area of the mobile terminal is obtained, the left-hand holding or the right-hand holding is identified according to the first capacitance change value and the second capacitance change value, the left-hand holding or the right-hand holding can be identified only by means of the capacitance change value of the sensor on the mobile terminal, and the left-hand and right-hand identification efficiency is improved.
Second embodiment
Referring to fig. 2, an embodiment of the present invention further provides a left-right hand identification method, which is applied to a mobile terminal and includes steps 201 to 206, which are described in detail below.
Step 201: after the fact that the mobile terminal is held is detected, a first capacitance value of a first sensor on a preset area on the left side of the mobile terminal is obtained.
In the embodiment of the invention, the preset area on the left side of the mobile terminal is specifically a lower area on the left side of a screen when the screen of the mobile terminal faces upwards. When the user holds the mobile terminal with the left hand, the palm of the left hand is generally located in the left preset area, and when the user holds the mobile terminal with the right hand, the fingers of the right hand are generally located in the left preset area.
The left preset area is provided with a first sensor, the first sensor is a capacitive metal sensor based on capacitance change, and the first sensor relates to a metal covering layer which can be equivalent to a capacitance plate.
What is to be obtained in step 201 is a first capacitance value of the first sensor after the user holds the mobile terminal with one hand.
Step 202: and calculating the difference value between the first capacitance value and the initial capacitance value of the first sensor to obtain a first capacitance change value.
Specifically, after the first capacitance value is obtained in step 201, the capacitance change value of the first sensor after the user holds the mobile terminal with one hand can be obtained by calculating the difference between the first capacitance value and the initial capacitance value of the first sensor.
Step 203: and acquiring a second capacitance value of a second sensor in a preset area on the right side of the mobile terminal.
In the embodiment of the invention, the preset area on the right side of the mobile terminal is specifically a lower area on the right side of a screen when the screen of the mobile terminal faces upwards. When the user holds the mobile terminal with the right hand, the palm of the right hand is generally located in the left preset area, and when the user holds the mobile terminal with the left hand, the fingers of the left hand are generally located in the right preset area.
The second sensor is also a capacitive metal sensor based on capacitance change, and relates to a metal covering layer, the realization principle is the same as that of the first sensor, and the calculation of the capacitance change value is the same as that of the first sensor.
In order to ensure the accuracy of right-hand and left-hand recognition according to the present invention, the metal coating layer of the first sensor is identical in material, thickness, and the like to the metal coating layer of the second sensor.
Step 204: and calculating the difference value between the second capacitance value and the initial capacitance value of the second sensor to obtain a second capacitance change value.
Specifically, after the second capacitance value is obtained in step 203, the capacitance change value of the second sensor after the user holds the mobile terminal with one hand can be obtained by calculating the difference between the second capacitance value and the initial capacitance value of the second sensor.
Step 205: and comparing the first capacitance change value with the second capacitance change value to obtain a comparison result.
Specifically, when a user holds the mobile terminal with one hand, the palm is usually on one side of the mobile terminal and the fingers are on the other side of the mobile terminal. If the mobile terminal is held by the left hand, the palm of the left hand is generally located in a left preset area of the mobile terminal, and meanwhile, the fingers of the left hand are located in a right preset area of the mobile terminal; if the mobile terminal is held by the right hand, the palm of the right hand is generally located in the right preset area of the mobile terminal, and the fingers of the right hand are located in the left preset area of the mobile terminal.
When a user holds the mobile terminal by a single hand, the contact areas of the palm and the fingers with the metal covering layers on the two sides of the mobile terminal are different, generally, the contact area of the palm is large, the contact area of the fingers is small, and therefore the influences on the capacitance values of the sensors on the two sides are different. Generally, the larger the contact area with the metal cover layer, the greater the influence on the capacitance value of the corresponding sensor.
Thus, by comparing the first capacitance change value and the second capacitance change value, it is possible to recognize whether the grip is a left-hand grip or a right-hand grip.
Step 206: when the comparison result is that the first capacitance change value is larger than the second capacitance change value, identifying that the hand is held by the left hand; or, when the comparison result is that the first capacitance change value is smaller than the second capacitance change value, the right-hand holding is identified.
Specifically, when the comparison result shows that the first capacitance change value is greater than the second capacitance change value, it indicates that the contact area between the hand and the metal covering layer of the first sensor is large compared with the second sensor, and it can be recognized that the hand is held by the left hand; and when the comparison result shows that the first capacitance change value is smaller than the second capacitance change value, the contact area between the hand and the metal covering layer of the second sensor is larger than that of the first sensor, and the hand is held by the right hand.
According to the left-hand and right-hand identification method, the left-hand holding or the right-hand holding can be identified only by means of the capacitance change value of the sensor on the mobile terminal, and the left-hand and right-hand identification efficiency is improved.
Third embodiment
Referring to fig. 3, an embodiment of the present invention further provides a left-right hand recognition method, which is applied to a mobile terminal and includes steps 301 to 304, which are described in detail below.
Step 301: the method comprises the steps of calibrating a first sensor on a preset area on the left side of the mobile terminal and a second sensor on a preset area on the right side of the mobile terminal, so that the initial capacitance value of the first sensor and the initial capacitance value of the second sensor are both 0.
In the embodiment of the invention, the preset area on the left side of the mobile terminal is specifically a lower area on the left side of a screen when the screen of the mobile terminal faces upwards. And the left preset area is provided with a first sensor which is a capacitive metal sensor based on capacitance change and relates to a metal covering layer, and the metal covering layer can be equivalent to a capacitance polar plate.
The preset area on the right side of the mobile terminal is specifically a lower area on the right side of the screen when the screen of the mobile terminal faces upwards. And the second sensor is also a capacitive metal sensor based on capacitance change, and relates to a metal covering layer, and the realization principle is the same as that of the first sensor.
In order to ensure the accuracy of right-hand and left-hand recognition according to the present invention, the metal coating layer of the first sensor is identical in material, thickness, and the like to the metal coating layer of the second sensor.
In an embodiment of the present invention, in order to reduce the processing procedure, before it is detected that the mobile terminal is held, the first sensor and the second sensor may be calibrated, so that the initial capacitance value of the first sensor and the initial capacitance value of the second sensor are both 0. Thus, the capacitance value of the sensor obtained subsequently is the capacitance variation value of the corresponding sensor.
Step 302: and acquiring a third capacitance value of the first sensor after the mobile terminal is detected to be held.
In this embodiment of the present invention, since the first sensor is calibrated before being held (i.e. calibrated to 0), the third capacitance value is a capacitance change value of the first sensor after the mobile terminal is held.
Step 303: a fourth capacitance value of the second sensor is obtained.
In this embodiment of the present invention, since the second sensor is calibrated before being held (i.e. calibrated to 0), the fourth capacitance value is a capacitance change value of the second sensor after the mobile terminal is held.
Step 304: and identifying whether the hand is held by the left hand or the right hand according to the third capacitance value and the fourth capacitance value.
Specifically, when a user holds the mobile terminal with one hand, the palm is usually on one side of the mobile terminal and the fingers are on the other side of the mobile terminal. If the mobile terminal is held by the left hand, the palm of the left hand is generally located in a left preset area of the mobile terminal, and meanwhile, the fingers of the left hand are located in a right preset area of the mobile terminal; if the mobile terminal is held by the right hand, the palm of the right hand is generally located in the right preset area of the mobile terminal, and the fingers of the right hand are located in the left preset area of the mobile terminal.
When a user holds the mobile terminal with a single hand, the contact areas of the palm and the fingers with the metal covering layers on the two sides of the mobile terminal are different, generally, the contact area of the palm is large, the contact area of the fingers is small, and therefore the influence on the capacitance values of the sensors on the two sides is different. Generally, the larger the contact area with the metal cover layer, the greater the influence on the capacitance value of the corresponding sensor.
Thus, from the third capacitance value and the fourth capacitance value, it is possible to recognize whether the grip is a left-hand grip or a right-hand grip.
Specifically, when the third capacitance value is larger than the fourth capacitance value, it indicates that the contact area between the hand and the metal covering layer of the first sensor is larger than that of the second sensor, and it can be recognized that the hand is held by the left hand; when the third capacitance value is smaller than the fourth capacitance value, it indicates that the contact area between the hand and the metal covering layer of the second sensor is larger than that of the first sensor, and it can be recognized that the hand is held by the right hand.
According to the left-hand and right-hand identification method, the left-hand holding or the right-hand holding can be identified only by means of the capacitance change value of the sensor on the mobile terminal, the left-hand and right-hand identification efficiency is improved, and the identification process can be simplified by calibrating the sensor.
