Detailed Description

The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.

Fig. 1 is a flowchart illustrating a temperature compensation method for a mobile terminal according to an embodiment of the present invention, where the temperature compensation method for the mobile terminal includes:

s101: and obtaining the current temperature of the mobile terminal according to a built-in heat dissipation system of the mobile terminal to obtain a current temperature value.

The mobile terminal may be a hardware device with various operating systems, such as a smart phone, a tablet computer, a personal digital assistant, and an electronic book.

Specifically, the higher the operating frequency and the longer the operating time of a Central Processing Unit (CPU) of the mobile terminal are, the higher the temperature value of the mobile terminal itself is, and if the mobile terminal is in a high-temperature working state for a long time, the service life of the mobile terminal may be shortened.

The temperature of the mobile terminal rises due to the influence of external factors (such as solar radiation, human body heat and the like) and internal factors (such as audio call, video call, charging and the like), the capacitance value of a capacitance sensor arranged on the mobile terminal is inconsistent due to sensing of holding data of a user at different temperatures of the mobile terminal, and in the prior art, the influence of the current temperature of the mobile terminal on the holding state detection accuracy is not considered when the holding state of the user is judged by the mobile terminal.

In the embodiment of the invention, in order to avoid the influence of the current temperature of different mobile terminals on the detection accuracy of the holding state, the current temperature value of the mobile terminal is used as a parameter for judging the holding state of the user.

Optionally, the current temperature of the mobile terminal may be obtained in real time through a built-in heat dissipation system of the mobile terminal, or the current temperature of the mobile terminal may also be obtained through the built-in heat dissipation system of the mobile terminal at intervals of a preset time to obtain a current temperature value, where the preset time may be set by a built-in program of the mobile terminal, or may be set by a user according to a requirement of the user.

The current temperature value of the mobile terminal obtained by the built-in heat dissipation system of the mobile terminal is, for example, 25 ℃.

Optionally, obtaining the current temperature of the mobile terminal according to a built-in heat dissipation system of the mobile terminal, and before obtaining the current temperature value, the method further includes: and starting the temperature compensation function of the mobile terminal.

S102: and acquiring a capacitance change threshold corresponding to the current temperature value according to the current temperature value and a preset relation data table, wherein the preset relation data table is used for identifying the corresponding relation between the temperature value of the mobile terminal and the capacitance change threshold of the capacitance sensor.

The preset relation data table comprises two parameters of the current temperature value of the mobile terminal and the capacitance change threshold value of the capacitance sensor. Different current temperature values correspond to different or the same capacitance change threshold. The mobile terminal can automatically select a capacitance change threshold corresponding to the current temperature value according to the current temperature value of the mobile terminal, so as to detect the holding state of the user.

For example, if the current temperature value of the mobile terminal obtained through the heat dissipation system built in the mobile terminal is, for example, 25 ℃, the capacitance change threshold corresponding to the current temperature value of 25 ℃ is 2000F (farad), and if the current temperature value of the mobile terminal obtained through the heat dissipation system built in the mobile terminal is, for example, 0 ℃, the capacitance change threshold corresponding to the current temperature value of 25 ℃ is 1000F.

Optionally, before obtaining the current temperature value according to a built-in cooling system of the mobile terminal, the method further includes: and acquiring a preset relation data table according to an experiment.

S103: and acquiring holding data of the mobile terminal, and acquiring the holding state of the user according to the holding data and the capacitance change threshold corresponding to the current temperature value.

In the embodiment of the present invention, the holding data is data detected by the hand-held sensor that the user holds the mobile terminal, and the holding data may be, for example, pressure data generated when the user presses the interface of the mobile terminal with fingers. The holding data can be single holding data or an average value of holding data for multiple times within a preset time range, and the preset time range can be preset according to requirements.

The holding data may be raw data or processed characteristic data. For example, in the present embodiment, the holding data may be the distance between the user's finger and any one of the four sides of the edge of the mobile terminal housing, and the original data of the contact area between the user's finger and any one of the four sides of the edge of the mobile terminal housing.

In particular, the holding data of the contact area of the user's finger and the interface of the mobile terminal can be detected by a hand-held sensor in the mobile terminal.

Wherein, holding the sensor and can be for example capacitive sensor, capacitive sensor's quantity can be four, and four capacitive sensor can set up respectively in four edges at mobile terminal shell edge, and four capacitive sensor overall arrangement form and hold the sensor.

A capacitive sensor is a sensor that converts a change in a measured quantity (e.g., size, pressure, contact area, etc.) into a change in capacitance.

It is understood that the grip sensor may be configured to detect the holding data of the user in real time, or may be configured to detect the holding data of the user at preset time intervals, where the preset time may be preset according to requirements.

Optionally, the holding state includes that the user holds the mobile terminal, and the mobile terminal obtains the holding state of the user according to the holding data and the capacitance change threshold corresponding to the current temperature value, including: judging whether the capacitance value of the capacitance sensor is larger than a capacitance change threshold value corresponding to the current temperature value or not; if the capacitance value of the capacitance sensor is larger than the capacitance change threshold value corresponding to the current temperature value, further judging whether the number of the capacitance sensors of which the capacitance values are larger than the capacitance change threshold value corresponding to the current temperature value reaches a preset number; and if the number of the capacitive sensors with the capacitance values larger than the capacitance change threshold value corresponding to the current temperature value reaches a preset number, the holding state is that the user holds the mobile terminal.

Optionally, the holding state further includes that the user does not hold the mobile terminal, and the mobile terminal obtains the holding state of the user according to the holding data and the capacitance change threshold corresponding to the current temperature value, and further includes: if the capacitance value of the capacitance sensor is smaller than the capacitance change threshold value corresponding to the current temperature value, or if the number of the capacitance sensors of which the capacitance value is larger than the capacitance change threshold value corresponding to the current temperature value does not reach the preset number, the holding state is that the user does not hold the mobile terminal.

Specifically, when the finger of the user touches any one of the four edges of the edge of the mobile terminal housing, at this time, the distance between the finger of the user and any one of the four edges of the edge of the mobile terminal housing is decreased, or the contact area between the finger of the user and any one of the four edges of the edge of the mobile terminal housing is increased, the capacitance values of the four capacitance sensors installed on the four edges of the edge of the mobile terminal housing are increased, and when the finger of the user does not touch the four edges of the edge of the mobile terminal housing, the capacitance value of the capacitance sensor is 0F (farad), therefore, firstly, the capacitance values of the four capacitance sensors after capacitance increase need to be calculated respectively according to the obtained holding data of the user, and compared with the capacitance change threshold value in the mobile terminal, when the capacitance value of one capacitance sensor after increase is greater than the capacitance change threshold value, the method can determine that the fingers of the user hold the edge of the mobile terminal shell where the capacitive sensor is located, and further determine that the user holds the mobile terminal if the number of the capacitive sensors (that is, the number of the edges of the mobile terminal shell where the fingers of the user hold the mobile terminal) with the increased capacitance values larger than the capacitance change threshold reaches a preset number.

Wherein the preset number is, for example, 2.

In this embodiment, for example, as shown in fig. 2, the schematic position diagram of the edge of the mobile terminal housing includes four positions, i.e., an upper position, a lower position, a left position and a right position, if the edge specifically held by the fingers of the user includes the left edge and does not include the right edge, the holding posture of the user may be determined as left-handed holding, if the edge specifically held by the fingers of the user includes the right edge and does not include the left edge, the holding posture of the user may be determined as right-handed holding, and if the edge specifically held by the fingers of the user includes the left edge and also includes the right edge, the holding posture of the user may be determined as left-handed holding, where left-handed holding, right-handed holding, and left-handed holding both indicate that the holding state of the user is.

In the embodiment, the capacitance change threshold corresponding to the current temperature value is obtained according to the current temperature value of the mobile terminal, and the holding state of the user is obtained according to the holding data and the capacitance change threshold corresponding to the current temperature value of the mobile terminal, so that the accuracy of detecting the holding state of the user by the mobile terminal can be improved, and the use experience of the user is effectively improved.

Fig. 3 is a flowchart illustrating a temperature compensation method for a mobile terminal according to another embodiment of the present invention, where the temperature compensation method for the mobile terminal includes:

s301: and acquiring a preset relation data table according to an experiment.

The preset relationship data table is used for identifying the corresponding relationship between the temperature value of the mobile terminal and the capacitance change threshold value of the capacitance sensor.

The preset relation data table comprises two parameters of the current temperature value of the mobile terminal and the capacitance change threshold value of the capacitance sensor. Different current temperature values correspond to different or the same capacitance change threshold. The user can obtain the corresponding relation between the temperature value of the mobile terminal and the capacitance change threshold value of the capacitance sensor in advance according to experiments to obtain a preset relation data table.

S302: and starting the temperature compensation function of the mobile terminal.

Specifically, when the user starts the temperature compensation function of the mobile terminal, step S303 is triggered to be executed, and if the user does not start the temperature compensation function of the mobile terminal, the current temperature of the mobile terminal is not acquired, and the holding state of the user is determined by using a capacitance change threshold preset by a built-in program of the mobile terminal.

Through the steps, a user can select whether to start the temperature compensation function of the mobile terminal according to the self requirement, and the flexibility of capacitance change threshold value conversion is improved.

S303: and obtaining the current temperature of the mobile terminal according to a built-in heat dissipation system of the mobile terminal to obtain a current temperature value.

On the other hand, in the step, the current temperature of the mobile terminal is obtained according to the built-in heat dissipation system of the mobile terminal instead of being detected by the temperature sensor, so that the manufacturing cost of the mobile terminal is effectively reduced.

S304: and acquiring a capacitance change threshold corresponding to the current temperature value according to the current temperature value and a preset relation data table.

S305: and acquiring holding data of the mobile terminal.

S306: and judging whether the capacitance value of the capacitance sensor is larger than a capacitance change threshold value corresponding to the current temperature value, if so, executing a step S307, and otherwise, executing a step S309.

Specifically, when the finger of the user touches any one of the four edges of the edge of the mobile terminal housing, at this time, the distance between the finger of the user and any one of the four edges of the edge of the mobile terminal housing is decreased, or the contact area between the finger of the user and any one of the four edges of the edge of the mobile terminal housing is increased, the capacitance values of the four capacitance sensors installed on the four edges of the edge of the mobile terminal housing are increased, and when the finger of the user does not touch the four edges of the edge of the mobile terminal housing, the capacitance value of the capacitance sensor is 0F (farad), therefore, firstly, the capacitance values of the four capacitance sensors after capacitance increase need to be calculated respectively according to the obtained holding data of the user, and compared with the capacitance change threshold value in the mobile terminal, when the capacitance value of one capacitance sensor after increase is greater than the capacitance change threshold value, it can be determined that a user's finger is held on the edge of the mobile terminal housing where the capacitive sensor is located.

For example, if the current temperature value of the mobile terminal obtained by the heat dissipation system built in the mobile terminal is, for example, 25 ℃, then the capacitance change threshold corresponding to the current temperature value of 25 ℃ is 2000F (farad), so that when the capacitance value of the capacitance sensor is greater than the capacitance change threshold 2000F corresponding to the current temperature value, step S307 is triggered to be executed, and when the capacitance value of the capacitance sensor is less than the capacitance change threshold 2000F corresponding to the current temperature value, step S309 is triggered to be executed.

S307: and judging whether the number of the capacitance sensors with the capacitance values larger than the capacitance change threshold value corresponding to the current temperature value reaches a preset number, if so, executing the step S308, and otherwise, executing the step S309.

Specifically, if the number of capacitive sensors (i.e., the number of edges of the edge of the housing of the mobile terminal held by the fingers of the user) whose increased capacitance value is greater than the capacitance change threshold value reaches a preset number, it may be determined that the user holds the mobile terminal.

Wherein the preset number is, for example, 2.

For example, if the current temperature value of the mobile terminal obtained by the heat dissipation system built in the mobile terminal is, for example, 25 ℃, then the capacitance change threshold corresponding to the current temperature value of 25 ℃ is 2000F (farad), so that when the number of capacitance sensors having capacitance values larger than the capacitance change threshold 2000F corresponding to the current temperature value is greater than or equal to 2, step S308 is triggered to be executed, and when the number of capacitance sensors having capacitance values larger than the capacitance change threshold 2000F corresponding to the current temperature value is smaller than 2, step S309 is triggered to be executed.

S308: and judging the holding state as that the user holds the mobile terminal.

For example, if the current temperature value of the mobile terminal obtained by the heat dissipation system built in the mobile terminal is, for example, 25 ℃, and the capacitance change threshold corresponding to the current temperature value of 25 ℃ is 2000F (farad), then when the capacitance value of the capacitance sensor is greater than the capacitance change threshold 2000F corresponding to the current temperature value, and the number of capacitance sensors having capacitance values greater than the capacitance change threshold 2000F corresponding to the current temperature value is greater than or equal to 2, it is determined that the holding state is that the user holds the mobile terminal.

S309: and judging that the holding state is that the user does not hold the mobile terminal.

For example, if the current temperature value of the mobile terminal obtained by the heat dissipation system built in the mobile terminal is, for example, 25 ℃, and the capacitance change threshold corresponding to the current temperature value of 25 ℃ is 2000F (farad), it is determined that the holding state is that the user does not hold the mobile terminal when the capacitance value of the capacitance sensor is smaller than the capacitance change threshold 2000F corresponding to the current temperature value, or when the number of capacitance sensors having capacitance values larger than the capacitance change threshold 2000F corresponding to the current temperature value is smaller than 2.

In the embodiment, the preset relation data table is obtained according to the experiment, the current temperature value of the mobile terminal is used as a parameter for judging the holding state of the user, the influence of the current temperatures of different mobile terminals on the detection accuracy of the holding state is avoided, the temperature compensation function of the mobile terminal can be started or not according to the requirement of the user by starting the temperature compensation function of the mobile terminal, and the flexibility of capacitance change threshold value transformation is improved. The current temperature of the mobile terminal is obtained according to the built-in heat dissipation system of the mobile terminal, so that the manufacturing cost of the mobile terminal is effectively reduced. The capacitance change threshold corresponding to the current temperature value is obtained according to the current temperature value of the mobile terminal, and the holding state of the user is obtained according to the holding data and the capacitance change threshold corresponding to the current temperature value of the mobile terminal, so that the accuracy of detecting the holding state of the user by the mobile terminal can be improved, and the use experience of the user is effectively improved.
