Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.
A mobile terminal heat dissipation control method, apparatus, and mobile terminal according to embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for controlling heat dissipation of a mobile terminal according to an embodiment of the present application.
As shown in fig. 1, a method for controlling heat dissipation of a mobile terminal according to an embodiment of the present application includes:
s101, when the mobile terminal enters a preset mode, detecting the use state data of the mobile terminal.
It should be noted that, in the embodiment of the present invention, the mobile terminal is in the default mode. That is to say, after entering the preset mode, the operation of the embodiment of the present invention is executed, so as to realize intelligent heat dissipation of the mobile terminal, that is, actively evacuate heat or guide a user to avoid a heating area of the mobile terminal.
In one embodiment of the present invention, the mobile terminal may provide a selection interface to prompt the user whether to enter the preset mode. The user can select whether to enter the preset mode according to the requirement. Or, the mobile terminal can be automatically controlled to enter the preset mode according to the working state of the mobile terminal. For example, when the mobile terminal is detected to be in a working state of video playing, game, voice call, etc. which may generate high heat, the mobile terminal may be automatically controlled to enter the preset mode.
After the mobile terminal is controlled to enter the preset mode, the use state data of the mobile terminal can be detected. The usage state data of the mobile terminal may include, but is not limited to, one or more of the following: the mobile terminal comprises a working state, a network state, an interfered state, attitude data, temperature information of a preset position, proximity information and the like. The preset position can be set according to a common contact position when a daily user uses the mobile terminal.
For example, the working state may be a call state, a game state, a video playing state, and the like.
The attitude data of the mobile terminal can be detected through sensors such as a gravity sensor, a gyroscope, an accelerometer and the like. The temperature information of the preset position can be detected through the temperature sensor, and the approach information of the preset position can be detected through the approach sensor. The greater the proximity information is, the closer the object is to the mobile terminal.
S102, analyzing the using state data and determining the contact mode of the mobile terminal and the user.
The contact mode of the mobile terminal with the user may include a non-contact mode, a hand-held mode, or a hand + head contact mode, etc. The non-contact mode is a mode in which the user does not contact the mobile terminal. The hand-held mode can be divided into a left-hand-held mode (as shown in FIG. 2 a) or a right-hand-held mode (as shown in FIG. 2 b). The hand + head contact mode may be a contact mode in which the user holds the mobile terminal in motion with the head close to the mobile terminal and the mobile terminal is in a call state, for example, a contact mode in which the user holds the mobile terminal close to the head during a call.
Therefore, the position of the user contacting the mobile terminal can be determined by analyzing the using posture of the mobile terminal, and the contact mode can be determined according to the contact position and the working state of the mobile terminal. For example, if it is detected that the temperature of the locations on both sides of the screen of the mobile terminal rises above a preset value in a short time, it may be determined that the contact mode is a hand-held mode, and it may be determined whether it is a left-hand-held mode or a right-hand-held mode according to the number of locations where the temperature rises on the specific sides. If the position of the mobile terminal close to the earphone is detected, namely the proximity information of the top of the mobile terminal is greater than a preset proximity value, and the mobile terminal is in a call state, the contact mode can be determined to be a head contact mode.
S103, guiding the user to avoid the heating area of the mobile terminal when contacting the mobile terminal according to the contact mode, and/or carrying out heat evacuation on the heating area contacted by the user.
In one embodiment of the present invention, if the contact mode is the first contact mode, the user is guided to avoid a heat generation area of the mobile terminal while contacting the mobile terminal.
The first touch mode may be a hand-held mode. If the contact mode of the user and the mobile terminal is the hand-holding mode, the user can be guided to hold the non-heating area in the mobile terminal when holding the mobile terminal, so that the influence of the heating area on heat dissipation caused by holding the heating area of the mobile terminal is avoided.
Further, in another embodiment of the present invention, if the contact mode is the first contact mode, the user is guided to avoid the heat generating area of the mobile terminal when contacting the mobile terminal, and the heat is evacuated from the heat generating area contacted by the user. Therefore, the heat dissipation device can guide a user to avoid a heating area, and can further evacuate heat of the heating area contacted by the user, so that the heat dissipation efficiency of the heating area is improved.
In one embodiment of the present invention, guidance information may be generated according to a position of a non-heat-generating area preset in a mobile terminal and a current contact position of the user with the mobile terminal, and the user may be guided.
That is, it may be determined whether a current contact position of the user with the mobile terminal at least partially falls within a heat generating area of the mobile terminal, and if so, a contact point suitable for the user to hold the mobile terminal may be determined according to a position of a non-heat generating area in the mobile terminal, and guidance information for guiding the user to adjust a hand-holding posture may be generated.
In the embodiment of the present invention, the guiding message may be in different forms, but not limited to, text, animation, voice, and the like.
In one embodiment of the present invention, if the contact mode is the second contact mode, heat is evacuated from the heat generating area contacted by the user.
The second contact mode may be a head contact mode, for example, a contact mode in which the head of the user is close to the earpiece during a call. Under this mode of contact, because the needs of conversation, the needs that the user is difficult to avoid contact the area that the mobile terminal earphone is located, consequently, the accessible to the user contact generate heat the region and carry out the heat evacuation, be about to generate heat the heat evacuation of region to non-heating region to this heat dissipation that generates heat region is accelerated, in order to avoid this heat generation region temperature to rise too fast.
In an embodiment of the present invention, the heat evacuation of the heat generating area contacted by the user may include: selecting a target area for heat evacuation according to a preset strategy; controlling the target area to be communicated with a heat conduction channel, and controlling the heating area contacted by the user to be communicated with the heat conduction channel; and controlling the heat conduction monomer of the heating area contacted by the user to conduct heat so as to evacuate the heat of the heating area contacted by the user to the target area through the heat conduction channel. The target area may be a non-heat-generating area, or an area where a user does not touch or has a small probability of touching.
Specifically, the mobile terminal may be divided into a plurality of regions in advance, and each region is provided with a heat conducting monomer, and the heat conducting monomers of each region may be connected through a heat conducting channel to perform heat transfer through the heat conducting channel. In addition, a connecting switch is arranged at the joint of each heat conduction monomer and the heat conduction channel, and the on and off of the switch corresponding to each heat conduction monomer can be controlled according to the heat diffusion requirement, so that the heat of the heat generating unit can be diffused to the area where the non-heat generating unit is located or the area with low user touch probability through the heat conduction channel.
For example, fig. 3 is a schematic view of a heat conducting structure of a mobile terminal according to an embodiment of the invention.
As shown in fig. 3, the mobile terminal can be divided into 6 areas, and the corresponding numbers are 1-6. A heat conducting channel C is provided in the mobile terminal, which is arranged on the vertical central axis in fig. 3. Each of the 6 regions is provided with a thermally conductive monomer D. Wherein, can control respectively whether the heat conduction monomer of each region communicates with heat conduction channel. For example, the heat conducting monomers in the areas 1, 3 and 5 can be controlled to be communicated with the heat conducting channels, and the heat conducting monomers in the areas 2, 4 and 6 can be controlled to be disconnected from the heat conducting channels.
Therefore, if the current user touches or touches the area with a high probability, the area 5 and the area 6 are the main heating area at the same time. And if the touch probability of the user is extremely low in the areas 1 and 2, the heat conduction monomers in the areas 3 and 4 can be controlled to be disconnected from the heat conduction channel, and the heat conduction monomers in the areas 1, 2, 5 and 6 are controlled to be communicated with the heat conduction channel. Therefore, the heat generated by the 5 and 6 regions can be diffused to the 1 and 2 regions through the heat conducting channel by the heat conducting monomer, and the effect of active heat dissipation is achieved.
The mobile terminal heat dissipation control method can detect the service state data of the mobile terminal when the mobile terminal enters a preset mode, and analyze the service state data, determine the contact mode of the mobile terminal and a user, and select and guide the user to avoid a heating area of the mobile terminal and/or evacuate heat to the heating area contacted by the user according to the contact mode, so that the user service state can be optimized in the use process of the mobile terminal, or the heat of the heating area contacted with the user is actively conducted to other areas, the temperature of the heating area is reduced, the heat dissipation effect of the mobile terminal can be effectively improved, further, the performance problem caused by temperature rise is avoided, and the user experience is improved.
Fig. 4 is a flowchart of a method for controlling heat dissipation of a mobile terminal according to another embodiment of the present invention.
As shown in fig. 4, in the heat dissipation control method of the mobile terminal according to the embodiment of the present application, step S102 may further include:
s401, respectively determining contact states of a plurality of first preset positions in the mobile terminal and a user according to the use state data, wherein the plurality of first preset positions are arranged on two sides of a screen of the mobile terminal.
In one embodiment of the present invention, a temperature sensor may be provided at each of the first preset positions to detect temperature information of the response position. And then, if the change values of the temperature information of the plurality of first preset positions in the preset time are respectively obtained, and the first preset positions with the change values larger than the preset threshold value are determined to be in contact with the user if the change values are larger than the preset threshold value.
For example, the first preset position may be set as shown in fig. 5 a. In the embodiment shown in fig. 5a, temperature sensors may be respectively disposed at eight locations A, B, C, D, E, F, G, H on the left and right sides of the mobile terminal to detect temperature information of the response location. If a human hand touches the detection area of the temperature sensor, the temperature sensor can acquire the temperature information change value of the contact area within a certain continuous time. If a temperature change value within a preset time is detected to be greater than a preset value at a certain position, it can be determined that the position is in contact with the user.
If the user does not touch the terminal device (like a desktop hands-free device), the temperature value change within the preset time collected by the temperature sensor at the position A, B, C, D, E, F, G, H is not larger than the preset value, i.e. the contact point is not detected.
If the user holds the mobile terminal with the right hand, at least 3 of the A, B, C, D four-position temperature sensors on the left side of the mobile terminal can detect that the temperature variation value within the preset time is larger than the preset threshold value, that is, at least 3 contact points can be detected in A, B, C, D four positions, and at least 1 of the E, F, G, H four-position temperature sensors on the right side can detect that the temperature variation value within the preset time is larger than the preset threshold value, that is, at least 1 contact point can be detected in E, F, G, H four positions.
Further, if the user holds the mobile terminal in his left hand, at least 1 contact point may be detected in A, B, C, D four positions and at least 3 contact points may be detected in E, F, G, H four positions.
S402, if the contact states of the first preset positions and the user meet preset conditions, determining that the contact mode is the first contact mode.
The contact state between the first preset positions and the user meets the preset condition, that is, the positions in the first preset positions, which are in contact with the user, accord with the preset distribution.
For example, for the embodiment shown in fig. 5a, if at least 3 contact points are detected on the left side and at least 1 contact point is detected on the right side, or at least 1 contact point is detected on the left side and at least 3 contact points are detected on the right side in the eight first preset positions A, B, C, D, E, F, G, H, the contact mode of the user with the mobile terminal may be determined as the first contact mode.
And S403, judging whether a second preset position of the mobile terminal is close to other objects or not according to the use state data, wherein the second preset position is arranged adjacent to a receiver position of the mobile terminal.
In one embodiment of the present invention, a proximity sensor may be disposed at the second preset position to detect proximity information of the second preset position, that is, a proximity value of the other object to the second preset position. And the larger the approach value is, the closer the other objects are to the second preset position.
In an embodiment of the present invention, it may be determined whether the proximity information of the second preset position is greater than a preset proximity value. And if the proximity information of the second preset position is larger than a preset proximity value, further determining the motion trend of the mobile terminal according to the attitude data, and judging whether the second preset position is close to other objects or not according to the motion trend. Specifically, it may be determined whether the movement trend of the mobile terminal is close to the object or far from the object, and if the mobile terminal is gradually close to the object and is very close to the object, it may be determined whether the second preset position is close to the object.
For example, as shown in fig. 5b, the distance between the object and the top of the mobile terminal can be detected by the sensors, and the turning motion of the mobile terminal can be detected by the acceleration sensor, so as to determine whether the top of the mobile terminal is close to the object by combining the data detected by the two sensors.
S404, if the second preset position is close to other objects, further judging whether the working state of the mobile terminal is a preset state.
The preset state may be a call state. In the embodiment of the invention, whether the mobile terminal is in a call state can be determined according to the radio frequency call state of the mobile terminal.
S405, if the working state of the mobile terminal is a preset state, determining that the contact mode with the user in the movement is the second contact mode.
It should be noted that the above embodiments are only exemplary, and in other embodiments of the present invention, the contact position between the user and the mobile terminal may be detected by other sensors, so as to determine the contact mode between the user and the mobile terminal. For example, in the implementation of determining the first contact pattern, the contact state of the user with each first preset position may also be detected by the proximity sensor. In the implementation of the second contact mode, which is short, it is also possible to detect whether another object is in contact with the second preset position by the temperature sensor.
In addition, the execution sequence of steps S403-S405 and steps S401-S402 is not sequential, or only steps S403-S405 or only steps S401-S402 may be executed.
Therefore, the contact position of the user and the mobile terminal can be analyzed through the use state data of the mobile terminal, the contact mode of the user and the mobile terminal is determined according to the detected contact position, the working state of the mobile terminal and other factors, automatic mode matching is achieved, the implementation is simple, the detection result is reliable, and the cost is low.
Corresponding to the method for detecting the heat generation of the mobile terminal provided by the embodiment, the application also provides a device for detecting the heat generation of the mobile terminal.
Fig. 6 is a schematic structural diagram of a mobile terminal heating detection apparatus according to an embodiment of the present application.
As shown in fig. 6, the heat generation detection apparatus of the mobile terminal according to the embodiment of the present application includes: a detection module 10, a determination module 20 and a control module 30.
Specifically, the detecting module 10 is configured to detect the usage status data of the mobile terminal when the mobile terminal enters the preset mode.
It should be noted that, in the embodiment of the present invention, the mobile terminal is in the default mode. That is to say, after entering the preset mode, the operation of the embodiment of the present invention is executed, so as to realize intelligent heat dissipation of the mobile terminal, that is, actively evacuate heat or guide a user to avoid a heating area of the mobile terminal.
In one embodiment of the present invention, the mobile terminal may provide a selection interface to prompt the user whether to enter the preset mode. The user can select whether to enter the preset mode according to the requirement. Or, the mobile terminal can be automatically controlled to enter the preset mode according to the working state of the mobile terminal. For example, when the mobile terminal is detected to be in a working state of video playing, game, voice call, etc. which may generate high heat, the mobile terminal may be automatically controlled to enter the preset mode.
After controlling the mobile terminal to enter the preset mode, the detection module 10 may detect the usage status data of the mobile terminal. The usage state data of the mobile terminal may include, but is not limited to, one or more of the following: the mobile terminal comprises a working state, a network state, an interfered state, attitude data, temperature information of a preset position, proximity information and the like. The preset position can be set according to a common contact position when a daily user uses the mobile terminal.
For example, the working state may be a call state, a game state, a video playing state, and the like.
The detection module 10 may detect the attitude data of the mobile terminal through a gravity sensor, a gyroscope, an accelerometer, and other sensors. The temperature information of the preset position can be detected through the temperature sensor, and the approach information of the preset position can be detected through the approach sensor. The greater the proximity information is, the closer the object is to the mobile terminal.
The determining module 20 is configured to analyze the usage status data and determine a contact mode of the mobile terminal with the user.
The contact mode of the mobile terminal with the user may include a non-contact mode, a hand-held mode, or a hand + head contact mode, etc. The non-contact mode is a mode in which the user does not contact the mobile terminal. The hand-held mode can be divided into a left-hand-held mode (as shown in FIG. 2 a) or a right-hand-held mode (as shown in FIG. 2 b). The hand + head contact mode may be a contact mode in which the user holds the mobile terminal in motion with the head close to the mobile terminal and the mobile terminal is in a call state, for example, a contact mode in which the user holds the mobile terminal close to the head during a call.
Therefore, the determining module 20 may determine the contact mode by analyzing the usage posture of the mobile terminal to determine the position of the user contacting the mobile terminal, and then comprehensively considering the contact position and the operating state of the mobile terminal. For example, if it is detected that the temperature of the locations on both sides of the screen of the mobile terminal rises above a preset value in a short time, it may be determined that the contact mode is a hand-held mode, and it may be determined whether it is a left-hand-held mode or a right-hand-held mode according to the number of locations where the temperature rises on the specific sides. If the position of the mobile terminal close to the earphone is detected, namely the proximity information of the top of the mobile terminal is greater than a preset proximity value, and the mobile terminal is in a call state, the contact mode can be determined to be a head contact mode.
The control module 30 is configured to guide the user to avoid the heat generating area of the mobile terminal when contacting the mobile terminal according to the contact mode, and/or to evacuate heat from the heat generating area contacted by the user.
In an embodiment of the present invention, as shown in fig. 7, the control module 30 may selectively guide the user to avoid the heat generating area of the mobile terminal when contacting the mobile terminal, or selectively evacuate the heat from the heat generating area contacted by the user according to different contact modes, or guide the user to avoid the heat generating area of the mobile terminal when contacting the mobile terminal, and evacuate the heat from the heat generating area contacted by the user.
In one embodiment of the present invention, the control module may include a guide unit 31 and a heat evacuation unit 32.
The guiding unit 31 is configured to guide the user to avoid a heat generating area of the mobile terminal when contacting the mobile terminal when the contact mode is the first contact mode.
The first touch mode may be a hand-held mode. If the contact mode between the user and the mobile terminal is the hand-held mode, the guiding unit 31 can guide the user to hold the non-heat-generating area of the mobile terminal while holding the mobile terminal, so as to avoid the influence of the heat-generating area on the heat dissipation due to the holding of the heat-generating area of the mobile terminal.
In an embodiment of the present invention, the guiding unit 31 may be configured to generate guiding information according to a position of a non-heat-generating area preset in the mobile terminal and a current contact position of the user with the mobile terminal, and guide the user.
That is, the guide unit 31 may determine whether a current contact position of the user with the mobile terminal at least partially falls on a heat-generating area of the mobile terminal, and if so, the guide unit 31 may determine a contact point suitable for the user to hold the mobile terminal according to a position of a non-heat-generating area in the mobile terminal and generate guide information for guiding the user to adjust a hand-holding posture.
In the embodiment of the present invention, the guiding message may be in different forms, but not limited to, text, animation, voice, and the like.
The heat evacuation module 32 is configured to evacuate heat from the heat generating area contacted by the user when the contact mode is the second contact mode.
The second contact mode may be a head contact mode, for example, a contact mode in which the head of the user is close to the earpiece during a call. In this contact mode, because of the requirement of communication, the user needs to contact the area where the mobile terminal receiver is located, which is difficult to avoid, so the heat evacuation module 32 can evacuate the heat of the heat generating area contacted by the user, that is, evacuate the heat of the heat generating area to the non-heat generating area, thereby accelerating the heat dissipation of the heat generating area, and avoiding the temperature of the heat generating area from rising too fast.
In one embodiment of the present invention, the heat evacuation module 32 may be configured to: selecting a target area for heat evacuation according to a preset strategy; controlling the target area to be communicated with a heat conduction channel, and controlling the heating area contacted by the user to be communicated with the heat conduction channel; and controlling the heat conduction monomer of the heating area contacted by the user to conduct heat so as to evacuate the heat of the heating area contacted by the user to the target area through the heat conduction channel.
Specifically, the mobile terminal may be divided into a plurality of regions in advance, and each region is provided with a heat conducting monomer, and the heat conducting monomers of each region may be connected through a heat conducting channel to perform heat transfer through the heat conducting channel. In addition, a connection switch is arranged at the connection position of each heat conduction unit and the heat conduction channel, and the heat evacuation module 32 can control the on and off of the switch corresponding to each heat conduction unit according to the heat diffusion requirement, so that the heat of the heat generating unit can be diffused to the area where the non-heat generating unit is located or the area with low user touch probability through the heat conduction channel.
The heat conducting structure of the heat dissipation module 32 according to an embodiment of the present invention can be as shown in fig. 3. The detailed description may refer to the method embodiment section.
In another embodiment of the present invention, the control module 30 is further configured to:
when the contact mode is the first contact mode, the user is guided by the guiding unit 31 to avoid the heat generating area of the mobile terminal when contacting the mobile terminal, and the heat generating area contacted by the user is thermally evacuated by the heat evacuation module 32. Therefore, the heat dissipation device can guide a user to avoid a heating area, and can further evacuate heat of the heating area contacted by the user, so that the heat dissipation efficiency of the heating area is improved.
The mobile terminal heat dissipation control device of the embodiment of the application can detect the service condition data of the mobile terminal when the mobile terminal enters a preset mode, and analyze the service condition data, determine the contact mode of the mobile terminal and a user, and select and guide the user to avoid the heating area of the mobile terminal and/or evacuate the heat of the heating area contacted by the user according to the contact mode, thereby being capable of optimizing the service condition of the user in the use process of the mobile terminal, or actively conducting the heat of the heating area contacted to other areas, reducing the temperature of the heating area, effectively improving the heat dissipation effect of the mobile terminal, further avoiding the performance problem caused by temperature rise, and improving the user experience.
Fig. 8 is a schematic structural diagram of a mobile terminal heat dissipation control device according to another embodiment of the present invention.
As shown in fig. 8, according to the mobile terminal heating detection apparatus of the embodiment of the present application, on the basis of fig. 6, the determining module 20 may further include: a first determining unit 21, a second determining unit 22, a first judging unit 23, a second judging unit 24, and a third determining unit 25.
The first determining unit 21 is configured to determine, according to the usage status data, contact statuses of a plurality of first preset locations in the mobile terminal and a user, where the plurality of first preset locations are disposed on two sides of a screen of the mobile terminal.
In one embodiment of the present invention, a temperature sensor may be provided at each of the first preset positions to detect temperature information of the response position. Furthermore, the first determining unit 21 may be configured to respectively obtain change values of the temperature information of the plurality of first preset positions within a preset time, and if the change values satisfy that the change values are greater than a preset threshold, determine that the first preset positions of which the change values are greater than the preset threshold are in contact with the user.
For example, the first preset position may be set as shown in fig. 5 a. In the embodiment shown in fig. 5a, temperature sensors may be respectively disposed at eight locations A, B, C, D, E, F, G, H on the left and right sides of the mobile terminal to detect temperature information of the response location. If a human hand touches the detection area of the temperature sensor, the temperature sensor can acquire the temperature information change value of the contact area within a certain continuous time. The first determination unit 21 may determine that a certain location is in contact with the user if a temperature change value within a preset time is detected at the location to be greater than a preset value.
If the user does not touch the terminal device (like a desktop hands-free device), the temperature value change within the preset time collected by the temperature sensor at the position A, B, C, D, E, F, G, H is not larger than the preset value, i.e. the contact point is not detected.
If the user holds the mobile terminal with the right hand, at least 3 of the A, B, C, D four-position temperature sensors on the left side of the mobile terminal can detect that the temperature variation value within the preset time is larger than the preset threshold value, that is, at least 3 contact points can be detected in A, B, C, D four positions, and at least 1 of the E, F, G, H four-position temperature sensors on the right side can detect that the temperature variation value within the preset time is larger than the preset threshold value, that is, at least 1 contact point can be detected in E, F, G, H four positions.
Further, if the user holds the mobile terminal in his left hand, at least 1 contact point may be detected in A, B, C, D four positions and at least 3 contact points may be detected in E, F, G, H four positions.
The second determining unit 22 is configured to determine the contact mode as the first contact mode when the contact states of the plurality of first preset positions and the user satisfy a preset condition.
The contact state between the first preset positions and the user meets the preset condition, that is, the positions in the first preset positions, which are in contact with the user, accord with the preset distribution.
For example, for the embodiment shown in fig. 5a, if at least 3 contact points are detected on the left side and at least 1 contact point is detected on the right side, or at least 1 contact point is detected on the left side and at least 3 contact points are detected on the right side in the eight first preset positions A, B, C, D, E, F, G, H, the second determining unit 22 may determine that the contact mode of the user with the mobile terminal is the first contact mode.
The first determining unit 23 is configured to determine whether a second preset position of the mobile terminal is close to another object according to the usage state data, where the second preset position is adjacent to a receiver position of the mobile terminal.
In one embodiment of the present invention, a proximity sensor may be disposed at the second preset position to detect proximity information of the second preset position, that is, a proximity value of the other object to the second preset position. And the larger the approach value is, the closer the other objects are to the second preset position.
In an embodiment of the present invention, the first judging unit 23 may be configured to judge whether the proximity information of the second preset position is greater than a preset proximity value; and if the proximity information of the second preset position is larger than a preset proximity value, further determining the motion trend of the mobile terminal according to the attitude data, and judging whether the second preset position is close to other objects or not according to the motion trend. Specifically, the first determination unit 23 may determine whether the movement tendency of the mobile terminal is close to the object or far from the object, and if the mobile terminal is gradually close to the object and is very close to the object, it may be determined whether the second preset position is close to the object.
For example, as shown in fig. 5b, the distance between the object and the top of the mobile terminal can be detected by the sensors, and the turning motion of the mobile terminal can be detected by the acceleration sensor, so as to determine whether the top of the mobile terminal is close to the object by combining the data detected by the two sensors.
The second determining unit 24 is configured to further determine whether the working state of the mobile terminal is a preset state when the second preset position is close to another object.
The preset state may be a call state. In an embodiment of the present invention, the second determining unit 24 may determine whether the mobile terminal is in a call state according to a radio frequency call state of the mobile terminal.
The third determining unit 25 is configured to determine, when the working state of the mobile terminal is a preset state, that the contact mode with the user in the movement is the second contact mode.
It should be noted that the above embodiments are only exemplary, and in other embodiments of the present invention, the contact position between the user and the mobile terminal may be detected by other sensors, so as to determine the contact mode between the user and the mobile terminal. For example, in the implementation of determining the first contact pattern, the contact state of the user with each first preset position may also be detected by the proximity sensor. In the implementation of the second contact mode, which is short, it is also possible to detect whether another object is in contact with the second preset position by the temperature sensor.
Therefore, the contact position of the user and the mobile terminal can be analyzed through the use state data of the mobile terminal, the contact mode of the user and the mobile terminal is determined according to the detected contact position, the working state of the mobile terminal and other factors, automatic mode matching is achieved, the implementation is simple, the detection result is reliable, and the cost is low.
