Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic block diagram illustrating a holding state recognition apparatus according to an exemplary embodiment, which may be applied to a terminal such as a mobile phone or a tablet computer. As shown in fig. 1, the apparatus includes:

the first sensing module 11 is configured to acquire fingerprint information of a user.

In one embodiment, the first sensing module may be a fingerprint sensor located in a groove of a rear shell of the mobile phone, a fingerprint sensor located in a menu key of the mobile phone, or a fingerprint sensor located in a screen of the mobile phone.

And the second sensing module 12 is configured to acquire contact point information and/or contact surface information of a user contacting the terminal.

In one embodiment, the second sensing module may be a capacitive sensor, and further, may be a self-inductance type capacitive sensor, or may be a mutual-inductance type capacitive sensor.

When a user touches the mobile phone, part of charges are transferred out of the capacitive sensor serving as the second sensing module, so that the charge distribution in the capacitive sensor is changed, the change condition of the charge distribution in the capacitive sensor is different according to the difference of the position and the area of the user touching the mobile phone, and whether the user holds the mobile phone can be determined according to the change condition of the charge distribution in the capacitive sensor.

And the fingerprint identification module 13 is respectively connected to the first sensing module and the second sensing module, and is configured to determine a fingerprint pattern according to the fingerprint information and determine a state of the terminal held by a user according to the contact point information and/or the contact surface information.

In one embodiment, the fingerprint identification module may be disposed near the first sensing module, for example, when the first sensing module is disposed in a groove of the rear cover of the mobile phone, the fingerprint identification module may be attached to a side of the first sensing module close to the screen. If the distance between the fingerprint identification module and the second sensing module is far, the fingerprint identification module and the second sensing module can be connected through structures such as a Printed Circuit Board (PCB) or a Flexible Printed Circuit (FPC).

In one embodiment, the user can hold the mobile phone by fixing the mobile phone with a plurality of fingers, and in this case, the user has more contact points with the mobile phone; the user can also hold the mobile phone in a mode that the palm holds the mobile phone, and under the condition, the contact area of the user to the mobile phone is large. When the user contacts the mobile phone in the non-holding state, for example, the user clicks a screen of the mobile phone, picks up the mobile phone and places the mobile phone in a pocket, and the like, the contact points of the user contacting the mobile phone are fewer and/or the contact area contacting the mobile phone is smaller, so that whether the mobile phone is in the holding state or not can be determined according to the contact point information and/or the contact surface information.

A power adjusting module 14 configured to adjust the power of the terminal radiated signal according to the state.

In one embodiment, the power adjusting module can reduce the power of the mobile phone radiation signal under the condition that the mobile phone is in a holding state, so that the damage of the mobile phone radiation to a human body is reduced.

In one embodiment, since the first sensing module and the second sensing module may be capacitive sensors, the difference between the calculation logics of the two signals is small, so that the fingerprint pattern can be determined by the fingerprint identification module according to the fingerprint information on the one hand, and the state of the terminal held by the user can be determined according to the contact point information and/or the contact area information on the other hand, without excessively adjusting the circuit logic in the fingerprint identification module. Therefore, a corresponding processing module does not need to be additionally added to the second sensing module, so that the overall hardware cost of the terminal can be reduced, and the weight of the terminal can be reduced.

Optionally, the second sensing module is an antenna.

In one embodiment, the second sensing module may be an antenna in a mobile phone, such as a Wi-Fi antenna, a GPS antenna, wherein the antenna may be made to resemble a mutual inductance type capacitor or a self-inductance type capacitor, so that it can change its charge distribution when a user touches the mobile phone.

By using the antenna inherent in the mobile phone as the second sensing module, a sensor for sensing the holding state of the mobile phone by the user does not need to be additionally configured, so that the hardware cost of the mobile phone and other terminals can be further reduced, and the weight of the mobile phone and other terminals can be reduced.

In one embodiment, the second sensing module may be time-division multiplexed, so as to ensure that the second sensing module can radiate a signal in each period, and contact point information and/or contact area information of a user contacting the terminal can be acquired, and the two functions do not interfere with each other. The first time period and/or the second time period may respectively include a plurality of sub-time periods, and each sub-time period may be equal or different.

Optionally, the second induction module is a near field communication antenna.

In one embodiment, the second sensing module may be a Near Field Communication (NFC) antenna. The near field communication antenna in the mobile phone is generally in the shape of a plurality of planar metal frames which are identical in shape, different in size and sleeved in sequence, or is a spiral planar metal, and the near field communication antenna in the shape has a large plane area, so that the near field communication antenna can be used as a self-inductance capacitor, the structures of other antennas in the mobile phone do not need to be modified, the near field communication antenna with the existing structure is directly used as a second induction module, and the cost of the mobile phone is reduced.

Fig. 2 is a schematic block diagram illustrating another holding state recognition apparatus according to an example embodiment. As shown in fig. 2, on the basis of the embodiment shown in fig. 1, the fingerprint identification module 13 includes:

a calculating submodule 131 configured to calculate the number of contacts of the user contacting the terminal according to the contact point information and/or calculate the contact area of the user contacting the terminal according to the contact area information;

a determination submodule 132 configured to determine that the terminal is held by a user if the number of contacts is greater than a preset number and/or the contact area is greater than a preset area; and determining that the terminal is not held by a user under the condition that the number of the contacts is less than or equal to the preset number and/or the contact area is less than or equal to the preset area.

In one embodiment, the user can hold the mobile phone by fixing the mobile phone with a plurality of fingers, and in this case, the user has more contact points with the mobile phone; the user can also hold the mobile phone in a mode that the palm holds the mobile phone, and under the condition, the contact area of the user to the mobile phone is large.

When the user contacts the mobile phone in a non-holding state, for example, the user clicks a screen of the mobile phone, picks up the mobile phone and places the mobile phone in a pocket, the number of contacts of the user contacting the mobile phone is small compared with the case of holding the mobile phone by a plurality of fingers, and/or the contact area of the user contacting the mobile phone is small compared with the case of holding the mobile phone by a palm holding the mobile phone. Therefore, the terminal can be determined to be in the holding state by the user when the number of the contacts is larger than the preset number (which can be set as required, for example, 5), and/or the contact area is larger than the preset area (which can be set as required, for example, 6 square centimeters), and the terminal can be determined to be in the non-holding state by the user when the number of the contacts is smaller than or equal to the preset number, and/or the contact area is smaller than or equal to the preset area, so that the accuracy of the judgment on the holding state is ensured.

Fig. 3 is a schematic block diagram illustrating yet another holding state recognition apparatus according to an example embodiment. As shown in fig. 3, based on the embodiment shown in fig. 2, the power adjusting module includes:

a reducing sub-module 141, configured to, in a case that the determining sub-module 132 determines that the terminal is held by the user, determine whether the power of the terminal radiation signal is greater than or equal to a preset power, and if so, reduce the power of the terminal radiation signal;

a boosting sub-module 142, configured to determine whether the power of the terminal radiation signal is less than a preset power if the determining sub-module 132 determines that the terminal is not held by the user, and if so, boost the power of the terminal radiation signal.

In one embodiment, in addition to reducing the power of the mobile phone radiation signal when the user holds the mobile phone, the power of the mobile phone radiation signal can be restored to a normal power level when the user does not hold the mobile phone. The power of the terminal radiation signal is compared with the preset power (which can be the normal power of the mobile phone radiation signal), so that the power of the mobile phone radiation signal can be prevented from being further reduced under the condition that the power of the mobile phone radiation signal is reduced, the communication is seriously influenced, and the power of the mobile phone radiation signal is prevented from being improved under the condition that the power of the mobile phone radiation signal is not reduced, and the user is greatly damaged.

Fig. 4 is a schematic block diagram illustrating yet another holding state recognition apparatus according to an example embodiment. As shown in fig. 4, on the basis of the embodiment shown in fig. 3, the apparatus further includes:

a detection module 15 configured to detect whether the terminal is in a communication state;

wherein, in a case that the detection module 15 detects that the terminal is in a communication state, the reducing submodule 141 reduces a first power value when reducing the power of the terminal radiation signal; in a case that the detection module 15 detects that the terminal is not in a communication state, the reducing submodule 141 reduces a second power value when reducing the power of the terminal radiation signal; the first power value is less than the second power value.

In one embodiment, when the user holds the mobile phone and the user does not communicate, for example, the user only holds the mobile phone in his hand to see a document, but the antenna in the mobile phone still radiates a signal, in this case, the power of the signal radiated by the antenna can be reduced to a greater extent, for example, the second power value can be reduced, the use of the mobile phone by the user is not affected, and the damage of the antenna radiation to the user can be ensured to be reduced. When a user holds the mobile phone and the user is communicating, in this case, the radiation power of the antenna can be reduced to a smaller extent, for example, the first power value is reduced, so that the damage of the radiation of the antenna to the user is reduced, and the excessive influence of the radiation of the antenna on the communication of the user is avoided.

Fig. 5 is a schematic block diagram illustrating yet another holding state recognition apparatus according to an example embodiment. As shown in fig. 5, on the basis of the embodiment shown in fig. 1, the apparatus further includes:

a gesture recognition module 16 configured to recognize gesture information of the terminal;

the power adjusting module 13 is configured to adjust the power of the terminal radiation signal according to the state determined by the fingerprint identification module when the posture information indicates that an included angle between a long side or a short side of the terminal and a horizontal plane is larger than a preset angle.

In one embodiment, since in some cases, the user holds the mobile phone, but the mobile phone is far away from the user, for example, the user turns on the hands-free during a call and holds the mobile phone far away from the user to listen, the radiation of the mobile phone has less influence on the user and the power of the signal radiated by the mobile phone does not need to be reduced.

Therefore, the gesture of the terminal can be recognized through the gesture recognition module, when it is determined that the included angle between the long side or the short side of the mobile phone and the horizontal plane is larger, for example, larger than a preset included angle (which can be set as required, for example, 60 °), it is indicated that the mobile phone is in a state close to the vertical horizontal plane, that is, a state where a user holds the mobile phone close to his ear to perform a call in a general situation, and therefore, in this situation, the power of the mobile phone radiation signal can be adjusted, for example, the adjustment is performed according to the mode of the embodiment shown in fig. 3, so that the accuracy of the adjustment is ensured, and the influence of unnecessary adjustment on the normal communication of.

Fig. 6 is a schematic block diagram illustrating yet another holding state recognition apparatus according to an example embodiment. As shown in fig. 6, on the basis of the embodiment shown in fig. 1, the apparatus further includes:

a distance identification module 17 configured to identify a distance between the terminal and a user;

wherein the power adjusting module 13 is configured to adjust the power of the terminal radiation signal according to the state determined by the fingerprint identification module if the distance between the terminal and the user is less than a preset distance.

Therefore, the distance from the terminal to the user can be identified through the distance identification module, and when the distance from the terminal to the user is smaller than a preset distance (which can be set according to needs, for example, 10 centimeters), the state that the user holds the mobile phone to be close to the ear of the user to carry out the call can be determined under the general condition, so that the power of the mobile phone radiation signal can be adjusted under the general condition, for example, the adjustment is carried out according to the mode of the embodiment shown in fig. 3, the accuracy of the adjustment is ensured, and the influence of unnecessary adjustment on the normal communication of the user is avoided.
