First embodiment

Reference picture 2, Fig. 2 are the system control method flow chart that first embodiment of the invention provides.

System control method in the present embodiment, including：

S201, the ultrasonic sensor transmission transmitted wave by being arranged in terminal；

S202, receive in predeterminable area, by user hand reflect transmitted waveform into back wave；

S203, detection transmitted wave and back wave wave character, judge user hand whether wearing gloves；

S204, if the determination result is YES, then adjust the operation layout of terminal.

In terminal technology, the touch-control of screen is always a critically important part, and it considers main including such as What can be simple and convenient, and precision height is quick on the draw, and takes into account durability and cost.It is now a kind of to develop screen the most ripe Curtain touch control manner is exactly capacitive touch screen, refer to Fig. 3, and Fig. 3 is the capacitive touch screen that first embodiment of the invention provides Touch-control schematic diagram.Capacitance plate touching technique, it is operated using the electric current sensing of human body.When user touches capacitance plate When, due to human body electric field, user's finger and working face form a coupled capacitor, because being connected to high-frequency signal on working face, in It is the electric current that finger walks a very little, this electric current flows out from the electrode on the four of screen angles respectively, and in theory Flow through that the electric current of four electrodes is proportional to the distance of finger to corner, then pass through the accurate meter to four current ratios Calculate, obtain out position.Capacitance plate can reach 99% position identification accuracy, and possess the response speed less than 3ms, be existing rank A kind of good interface hardware being applied on touch screen of section, has obtained most commonly used application.

The characteristics of due to capacitance plate, when user's wearing gloves, capacitance plate can not be carried out normally between the hand of user The circulation of electric current, capacitance plate cannot be perceived accurately, the position that the hand of user is placed, the operation carried out, be performed Instruction.And because the making of present capacitance plate is more and more accurate, be not the insulating glove specially dressed, i.e. rubber gloves Under the premise of, when user's wearing gloves, screen still can produce certain reaction to the operation of user, simply this reaction phase It is excessively faint compared with for user not wearing gloves, and discrimination is lower.

In S201, transmitted wave is sent by the ultrasonic sensor being arranged in terminal.Ultrasonic sensor, it is a kind of normal It is applied to the sensor of ranging for rule, because ultrasonic wave has directive property strong, energy expenditure is slow, in media as well propagation distance Farther out the characteristics of, thus ultrasonic wave can be applied in the measurement of distance.During measurement, its specific principle is ultrasonic transmitter Launch transmitted wave to certain direction, timing while transmitting, ultrasonic wave is propagated in atmosphere, is run into barrier and is just returned immediately instead Ejected wave, and stop timing when receiving back wave.Then, it is 340m/s and biography based on the speed that sound wave is propagated in atmosphere The time broadcast, it is possible to the distance between ultrasonic sensor and barrier is calculated.

In addition, in the present embodiment, before the ultrasonic sensor by being arranged in terminal sends transmitted wave, may be used also With including：Judge whether to meet the preparatory condition for enabling ultrasonic sensor；If meeting preparatory condition, supersonic sensing is enabled Device.Wherein, preparatory condition can include：Terminal receives the instruction of Client-initiated bright screen；Or, terminal is in normal use. In order to avoid maloperation as far as possible, avoid just enabling ultrasonic sensor progress sound wave on the premise of user does not have wish Hair is received, and causes the waste of terminal electric energy, by setting preparatory condition, to realize the control whether enabled to ultrasonic sensor System, adds a lock equivalent to ultrasonic sensor, only on the premise of unblock, enables ultrasonic sensor just now.This implementation The preparatory condition referred in example includes：Terminal receives the instruction of Client-initiated bright screen, and this condition characterizes, and whether user Be i.e. by using terminal, wherein, bright screen instruction often with unlock instruction together, the form of wherein bright screen instruction can wrap Include：Power key wakes up, double-clicks terminal screen wake-up, gravity and acceleration transducer wake-up etc..These wake-up modes, in other words Unlocking manner, in other words bright screen mode can serve as the reference of the preparatory condition in the present embodiment.In addition, preparatory condition may be used also With including terminal is in normal use.The present embodiment shows the relation between both preparatory conditions, table by "or" Show any one in both are met, be considered as meeting preparatory condition, ultrasonic sensor can be enabled.

In S202, receive in predeterminable area, by user hand reflect transmitted waveform into back wave.In the present embodiment In, because it is applied to user's touch control terminal, then, predeterminable area is traditionally arranged to be the top certain limit of terminal screen, phase Answer, the ultrasonic sensor in terminal, which sends transmitted wave, only to be launched in the range of this.In addition, want in user During operating handset, the part except gripping terminal, often with the presence of the hand of user in the range of this, then in the range of this Can directly reflects transmitted wave simply by the hand of user, forms back wave.

In S203, detect the waveform characteristic of transmitted wave and back wave, judge user hand whether wearing gloves.In this implementation In example, transmitted wave is generated by ultrasonic sensor, and its waveform characteristic is fixed, it is however generally that does not have larger change Change；And back wave is the sound wave after being reflected by barrier, due to the difference of the surface profile of barrier, the waveform of back wave Characteristic can change to a certain extent.Surface profile mentioned here refers to the profile in smaller range, for example uses Profile of the hand at family in the range of finger tip, refer to Fig. 4, and Fig. 4 shows surface profile of the hand in finger tip a small range of user Schematic diagram.Obviously, the difference very little between the hand and hand of the user in the range of this, almost can be ignored, because together Roughness of the different fingers of one user etc. is all similar.But when user has once worn gloves, that situation just becomes It is entirely different, surface profile becomes the profile of gloves from the profile of the hand of user.The hand of the characteristics of gloves and user has been Complete different, its roughness can be higher than the hand of user, because gloves inevitably have the vestige of the braiding of fiber, refer to In the case that Fig. 5, Fig. 5 show wearing gloves, surface profile schematic diagram of the gloves in finger tip a small range.From Fig. 4's and Fig. 5 Contrast can be seen that the surface roughness of wearing gloves apparently higher than hand, and in this case, ultrasonic wave is by both reflections The wave character of back wave afterwards will become far different.

Specifically, in the present embodiment, the waveform characteristic of transmitted wave and back wave is detected, judges whether the hand of user is worn Gloves can include：The amplitude of transmitted wave and back wave is detected, reflectivity is obtained according to both amplitudes；According to reflectivity, with Corresponding relation between default reflectivity and reflecting medium, judge user hand whether wearing gloves.In the present embodiment, it is right Both amplitude features are mainly may be referred in the waveform characteristic of transmitted wave and back wave.Amplitude has reacted the size of energy, sound For ripple when by dieletric reflection, surface roughness is higher, and its absorbed energy is more, and the energy of the back wave after reflection is got over It is small, it is, relative to comparing after the hand and wearing gloves of user, reflect the amplitude of back reflection ripple, meeting by the hand of user It is slightly less than the amplitude of transmitted wave, and after wearing gloves, the amplitude of back wave can then be considerably less than the amplitude of transmitted wave.Pass through Amplitude in the wave character of transmitted wave and back wave, it is known that the energy magnitude relationship of transmitted wave and back wave, so as to base Reflectivity can be further learnt in energy magnitude relationship.When energy attenuation is smaller between transmitted wave and back wave, reflectivity It is then bigger, illustrate that reflecting surface is more smooth；When energy attenuation is bigger between transmitted wave and back wave, reflectivity is then smaller, says Bright reflecting surface is more coarse.Between the gloves of unlike material, such as cotton, polyester fiber etc., its reflectivity is also different, Pass through the accumulation of the reflectivity of the gloves to unlike material, it is possible to which, according to the value of the reflectivity measured, determining the hand of user is It is no to have worn gloves, even, wearing be what material gloves.

In S204, if it is determined that result be it is yes, then adjust terminal operation layout.Judged result is yes, then explanation is used The hand at family has worn gloves；So, on the premise of gloves have been worn, the operation layout of terminal is adjusted, in order to which user is carried out Corresponding operation.Wherein, adjusting the operation layout of terminal can include：Fingerprint module in closing a terminal.Obviously, when user's After hand has worn gloves, before user ungloves, fingerprint function all in None- identified state because not having just True fingerprint supplies terminal recognition, and the fingerprint of user is covered by gloves profile.In this case, the fingerprint closed a terminal Module, system resource can be preferably saved, avoid insignificant electricity and memory consumption.

After fingerprint module is closed, some need the scene for using fingerprint originally, it is possible to pass through other alternatives Formula is directly carried out, such as：Terminal unlocking, after fingerprint module is closed, it can not be unlocked by fingerprint, then, The interface of password unblock or pattern unblock is directly presented to user, allows user to carry out the behaviour of terminal unlocking by corresponding mode Make, ensure that safety does not delay the time of user's operation yet.Also for example, fingerprint is paid, and after fingerprint module is closed, can not be led to Fingerprint is crossed to complete payment function, then, in this case, directly present password pay, recognition of face pay etc. other The interface of the means of payment, and the interface that fingerprint is paid no longer is shown, it is also possible to while security is ensured, lifting is paid Efficiency.

In the present embodiment, adjusting the operation layout of terminal can also include：Amplify the display layout of content in screen； And/or reduce activation threshold value to the touch control operation of terminal, lifting operation sensitivity.In the present embodiment, the behaviour of terminal is adjusted When being to improve user's wearing gloves as layout, it is inconvenient for operation the problem of, this is primarily present problems with：Wearing gloves it Afterwards, sensitivity decrease of the user to the touch-control of screen.So, for this, a kind of feasible mode is：Amplify content in screen Display layout.Wherein, amplifying the display layout of the content in screen, include but is not limited to, icon, the element such as font becomes big, from And cause, the touch area of corresponding position is also relative to become big.Fig. 6 is refer to, Fig. 6 shows a kind of touching for the icon after amplification Schematic diagram is controlled, because the touch-control scope of the icon of correspondence position becomes big, then, it is accurate needed for the operation to the icon of the position Degree reduces, and the exercisable scope of user is bigger, it is clear that can be with the sensitivity of lifting operation., then can be with and the content such as font becomes big After improving due to wearing gloves, the content such as occlusion issue, amplification font that the hand of user becomes much larger and come to screen belt is then The more preferable reading experience of user can be given.Specifically, the display layout of content can pass through in amplification screen：Show in reduction system The DPI (Dots Per Inch, the pixel of per inch) shown, can thus realize the amplification to display layout, so as to be lifted The sensitivity of operation.

In addition, also a kind of feasible mode is to reduce the activation threshold value to the touch control operation of terminal, lifting operation is sensitive Degree.When user's touch control terminal screen, corresponding capacitance is produced to realize the operation to terminal.But when capacitance is enough Hour, system is will not be aitiogenic to this capacitance, it is necessary to waits this capacitance to reach certain size, is just considered as this Operation is normal corresponding to capacitance, is otherwise exactly maloperation.In the scene of user's wearing gloves, capacitance be compared to It is usually smaller, then, now it may be referred to currently wear with regard to the required capacitance of in good time reduction operation, this amplitude reduced Relation between glove reflectivity, and the reflectivity of not wearing gloves obtains, so as to lift the hand touch-control of user behaviour The success rate of work, reduction are considered as the probability of maloperation, also just improve the sensitivity of operation.

A kind of system control method is present embodiments provided, transmitting is sent by the ultrasonic sensor being arranged in terminal Ripple, receive in predeterminable area, by the hand of user reflect transmitted waveform into back wave, detect the waveform of transmitted wave and back wave Characteristic, judge user hand whether wearing gloves；If the determination result is YES, then the operation layout of terminal is adjusted.By this implementation The implementation of example, the object features come using the ultrasonic sensor in terminal as detection means in detection range, with sound wave not The feature of the hand of user is determined with the wave characteristics reflected on medium, can accurately judge whether user has worn gloves, so The operation for adjusting terminal according to gloves afterwards is laid out, and is provided facility for glove user operation, is improved Consumer's Experience.

In S704, detect the waveform characteristic of transmitted wave and back wave, judge user hand whether wearing gloves.In this implementation In example, transmitted wave is generated by ultrasonic sensor, and its waveform characteristic is fixed, it is however generally that does not have larger change Change；And back wave is the sound wave after being reflected by barrier, due to the difference of the surface profile of barrier, the waveform of back wave Characteristic can change to a certain extent.Surface profile mentioned here refers to the profile in smaller range, for example uses Profile of the hand at family in the range of finger tip, refer to Fig. 4, and Fig. 4 shows surface profile of the hand in finger tip a small range of user Schematic diagram.Obviously, the difference very little between the hand and hand of the user in the range of this, almost can be ignored, because together Roughness of the different fingers of one user etc. is all similar.But when user has once worn gloves, that situation just becomes It is entirely different, surface profile becomes the profile of gloves from the profile of the hand of user.The hand of the characteristics of gloves and user has been Complete different, its roughness can be higher than the hand of user, because gloves inevitably have the vestige of the braiding of fiber, refer to In the case that Fig. 5, Fig. 5 show wearing gloves, surface profile schematic diagram of the gloves in finger tip a small range.From Fig. 4's and Fig. 5 Contrast can be seen that the surface roughness of wearing gloves apparently higher than hand, and in this case, ultrasonic wave is by both reflections The wave character of back wave afterwards will become far different.

In S705, if it is determined that result be it is yes, then adjust terminal operation layout.Judged result is yes, then explanation is used The hand at family has worn gloves；So, on the premise of gloves have been worn, the operation layout of terminal is adjusted, in order to which user is carried out Corresponding operation.Wherein, adjusting the operation layout of terminal can include：Fingerprint module in closing a terminal.Obviously, when user's After hand has worn gloves, before user ungloves, fingerprint function all in None- identified state because not having just True fingerprint supplies terminal recognition, and the fingerprint of user is covered by gloves profile.In this case, the fingerprint closed a terminal Module, system resource can be preferably saved, avoid insignificant electricity and memory consumption.

In the present embodiment, adjusting the operation layout of terminal can also include：Amplify the display layout of content in screen； And/or reduce activation threshold value to the touch control operation of terminal, lifting operation sensitivity.In the present embodiment, the behaviour of terminal is adjusted When being to improve user's wearing gloves as layout, it is inconvenient for operation the problem of, this is primarily present problems with：Wearing gloves it Afterwards, sensitivity decrease of the user to the touch-control of screen.So, for this, a kind of feasible mode is：Amplify content in screen Display layout.Wherein, amplifying the display layout of the content in screen, include but is not limited to, icon, the element such as font becomes big, from And cause, the touch area of corresponding position is also relative to become big.Fig. 6 is refer to, Fig. 6 shows a kind of touching for the icon after amplification Schematic diagram is controlled, because the touch-control scope of the icon of correspondence position becomes big, then, it is accurate needed for the operation to the icon of the position Degree reduces, and the exercisable scope of user is bigger, it is clear that can be with the sensitivity of lifting operation., then can be with and the content such as font becomes big After improving due to wearing gloves, the content such as occlusion issue, amplification font that the hand of user becomes much larger and come to screen belt is then The more preferable reading experience of user can be given.Specifically, the display layout of content can pass through in amplification screen：Show in reduction system The DPI shown, the amplification to display layout can be thus realized, so as to the sensitivity of lifting operation.
