For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

The invention discloses a kind of control method of handheld device, the unhandy problem of release handheld device existing for solving user's one-handed performance handheld device process, the security that simultaneously improves handheld device.This handheld device comprises display screen and pressure sensing cell, the pressure that this pressure sensing cell bears for detection of this display screen, and this handheld device can be mobile phone, panel computer and palm PC.

Referring to Fig. 1, the process flow diagram of the control method that Fig. 1 is a kind of handheld device disclosed by the invention.This control method comprises:

Step S11: under screen lock state, controlled pressure detecting unit detection display shields the force value of bearing, and obtains this force value.

Detect the running status of handheld device, when definite handheld device is during in screen lock state, controlled pressure detecting unit carries out pressure detection.This pressure sensing cell can be arranged at the downside of display screen, or is arranged at the downside of the panel of display screen, and the present invention does not limit the particular location of pressure sensing cell, as long as ensure that pressure sensing cell can shield the pressure bearing by detection display.

Step S12: judge that whether force value meets first pre-conditioned, obtain the first judged result.

First pre-conditionedly at least comprises that the force value of obtaining is greater than the first pressure threshold.This first pressure threshold can be the original start of electronic equipment, also can in use be set voluntarily by user.If user needs release handheld device, can strengthen the dynamics of touch display screen, the corresponding increase of pressure that now display screen of electronic equipment bears.

Step S13: meet first when pre-conditioned when the first judged result shows force value, control the default prompting of handheld device output.

The force value of bearing when display screen meets first when pre-conditioned, controls the default prompting of handheld device output.This default prompting has various ways, for example: audio-frequency information output unit (loudspeaker or audio amplifier) output voice message, the control display screen controlled in handheld device show that release control, control display screen show dummy keyboard, or control display output character and point out.In the time that user acts on pressure on the display screen of handheld device and is greater than pressure threshold, just can start the operation of release handheld device, and not need to press the unlocking function key of handheld device.

Step S14: judge whether to receive user's predetermined registration operation, obtain the second judged result.

Step S15: in the time that the second judged result shows to receive user's predetermined registration operation, control display screen operation display interface.

After the default prompting of handheld device output, detect user and whether carry out predetermined registration operation, this predetermined registration operation is the operation corresponding with the default prompting of handheld device output.If determine that user has carried out the operation corresponding with the default prompting of handheld device output, controls display screen operation display interface, with release handheld device.It should be noted that, the operation interface that display screen shows can be predefined operation interface, and as the main interface of handheld device, certainly, the operation interface that display screen shows can be also that handheld device enters the operation interface showing before screen lock state.

In the control method of the above-mentioned disclosed handheld device of the present invention, when handheld device is during in screen lock state, detect in real time by pressure sensing cell the force value that in handheld device, display screen bears, when the force value of bearing at this display screen is greater than the first pressure threshold, the default prompting of handheld device output, when definite user carries out and this default prompting after corresponding predetermined registration operation, just can complete unlocking operation.For user, only need to increase the dynamics of the display screen that touches handheld device, just can start the operation of release handheld device, carry out afterwards the release that corresponding operation just can complete handheld device, in whole releasing process, without the unlocking function key by handheld device, in the time of user's one-handed performance, also can complete easily the release of handheld device.In addition, while being greater than pressure threshold due to the force value of only bearing at display screen, just can start unlocking operation, with in prior art, only need press unlocking function key and just can start compared with unlocking operation, increase the difficulty of disabled user's release handheld device, the security that has improved accordingly handheld device.

In the control method of above-mentioned disclosed handheld device, first pre-conditionedly only comprises that the force value of obtaining is greater than the first pressure threshold.If because object touches or user's maloperation, when the force value that causes the display screen of handheld device to bear is greater than the first pressure threshold, based on above-mentioned the first pre-conditioned operation that also can the default prompting of triggering following output, although can release handheld device, but the operation of prompting is preset in handheld device output, also can increase the power consumption of handheld device.In order to reduce because object touches or user misoperation may cause the probability of the default prompting of handheld device output, can be to the first pre-conditioned improvement.

In enforcement, first pre-conditionedly can also be: the force value of obtaining is greater than the first pressure threshold, and the area in region that force value is greater than the first pressure threshold is in preset area interval.Accordingly, judge whether force value met for the first pre-conditioned comprising: whether the force value that judgement is obtained is greater than the first pressure threshold, if not, determine do not meet first pre-conditioned, if, determine that force value is greater than the area in the region of the first pressure threshold, and judge that whether this area is in preset area interval, when this area is in the time that preset area is interval, determine meet first pre-conditioned, when this area is in the time that preset area is interval, determine do not meet first pre-conditioned.This preset area interval can be the original start of handheld device, also can in use be set voluntarily by user.Because user is in the process of release handheld device, conventionally only use a finger, therefore can point the area contacting with display screen according to user and set this preset area interval.

In user is put in handheld device pocket or bag time, other objects in pocket or bag may contact the display screen of handheld device, but the display screen of object contact handheld device is generally two kinds of situations, a kind of display screen of the edge extruding handheld device that is object, the area that now object contacts with display screen is very little, another kind is the display screen of the monolithic extruded handheld device of object, and now the area of object and display screen is very large.Therefore, the area that the display screen of handheld device is touched by object is very little in the probability in preset area interval, by judging that whether area that force value is greater than pressure threshold is in preset area interval, just can reduce the display screen that touches handheld device due to object and export the probability of default prompting.

First pre-conditionedly can also be: the force value of obtaining is greater than the first pressure threshold, and is less than the second pressure threshold, and the second pressure threshold is greater than the first pressure threshold.Accordingly, judge whether force value met for the first pre-conditioned comprising: whether the force value that judgement is obtained is greater than the first pressure threshold, if not, determine not meet first pre-conditionedly, whether the force value that if so, judgement is obtained is less than the second pressure threshold, in the time that force value is less than the second pressure threshold, determine meet first pre-conditioned, in the time that force value is more than or equal to the second pressure threshold, determine do not meet first pre-conditioned.Certainly, also can first judge whether the force value of obtaining is less than the second pressure threshold, in the time that force value is less than the second pressure threshold, more further judge whether this force value is greater than the first pressure threshold.

Object touches or when the display screen of user misoperation handheld device, the pressure that acts on display screen often cannot be in the force value interval of the first pressure threshold and the second pressure threshold formation, therefore, can reduce the maloperation of touching display screen or user due to object and export the probability of default prompting.

First pre-conditionedly can also be: the force value of obtaining is greater than the first pressure threshold, and the state duration that force value is greater than pressure threshold reaches Preset Time threshold value.Accordingly, judge whether force value met for the first pre-conditioned comprising: whether the force value that judgement is obtained is greater than the first pressure threshold, if not, determine not meet first pre-conditionedly, if so, add up the state duration that force value is greater than pressure threshold, and judge whether the lasting time reaches Preset Time threshold value, in the time that this lasting time reaches Preset Time threshold value, determine meet first pre-conditioned, otherwise determine do not meet first pre-conditioned.

In the time that object touches the display screen of handheld device or user misoperation, may cause pressure sensing cell to detect the force value obtaining and be greater than the first pressure threshold, but, the time that object touches or user misoperation is lasting can be very short, therefore, by judging whether the state duration that force value is greater than the first pressure threshold reach Preset Time threshold value, just can reduce the maloperation of touching display screen or user due to object and export the probability of default prompting.

In addition, in the control method of the above-mentioned disclosed handheld device of the present invention, control the default prompting of handheld device output, except the audio-frequency information output unit in previously described control handheld device (loudspeaker or audio amplifier) output voice message, control display screen show release control, control display screen demonstration dummy keyboard, or outside the prompting of control display output character, also comprise: control display screen and show that release prompting control or control display screen show input password prompt control.Describe for the subsequent operation of the default prompting of various output respectively below.

In the time of handheld device control audio-frequency information output unit output voice message, judge whether to receive user's predetermined registration operation, comprising: judge whether to receive the operation corresponding with this voice message that user carries out.Determine when handheld device the force value that gets and meet first when pre-conditioned, control the audio-frequency information output unit output voice message of self, this voice message comprises prompting user and continues to carry out the voice messaging of certain operation.For example, the voice message that output prompting user presses certain function key on handheld device panel, or export prompting user and carry out the voice message of clicking operation at display screen, the present invention will not enumerate.After the audio-frequency information output unit output voice message of controlling in handheld device, if receive operation corresponding to the voice message with the output of audio-frequency information output unit that user carries out, control display screen operation display interface, complete the release of handheld device.

In the time that handheld device control display screen shows release control, judge whether to receive user's predetermined registration operation, comprising: judge whether user moves this release control according to preset direction.Determine when handheld device the force value that gets and meet first when pre-conditioned, the display screen of controlling self shows release control, this release control can be consistent with release control of the prior art, if user need to carry out unlocking operation, moves this release control along preset direction.In the time that definite user moves release control according to preset direction, control display screen operation display interface, complete the release of handheld device.

In the time that handheld device control display output character is pointed out, judge whether to receive user's predetermined registration operation, comprising: judge whether to receive the operation corresponding with this text prompt that user carries out.Determine when handheld device the force value that gets and meet first when pre-conditioned, control the display screen display text prompting of self, this text prompt comprises prompting user and continues to carry out the Word message of certain operation.For example, display reminding user presses the text prompt of certain function key on handheld device panel, or display reminding user carries out the text prompt of clicking operation at display screen, and the present invention will not enumerate.After the display screen display text prompting of controlling in handheld device, if receive operation corresponding to the text prompt showing with display screen that user carries out, control display screen operation display interface, complete the release of handheld device.

In the time that handheld device control display screen shows release prompting control, judge whether to receive user's predetermined registration operation, comprise following any one:

1) judge whether user stops pressing display screen in the first Preset Time.

When acting on force value on the display screen of handheld device, user meets first when pre-conditioned, handheld device control display screen shows release prompting control, afterwards, user will stop, to the pressing of display screen, just can completing the release of handheld device in the first Preset Time.

In the process of whole release handheld device, user only need carry out the operation of once pressing display screen, as long as stop pressing display screen in the first Preset Time after display screen shows release prompting control.Compared with previously described mode, further simplify the operation of release handheld device.

2) whether the pressing operation duration that judges user exceedes the second Preset Time.

When acting on force value on the display screen of handheld device, user meets first when pre-conditioned, handheld device control display screen shows release prompting control, and the time that starts counting user and press display screen, in the time that the lasting time of user's pressing operation exceedes the first Preset Time, control display screen operation display interface, complete the release of handheld device.

In the process of whole release handheld device, user is same only needs to carry out the operation of once pressing display screen, as long as ensure that pressing operation continues the second Preset Time after display screen shows release prompting control.Compared with aforementioned manner, further simplify the operation of release handheld device.Simultaneously, if it is to touch or user's maloperation causes due to object that handheld device control display screen shows release prompting control, owing to only reaching just meeting release handheld device of the second Preset Time in the pressing operation duration, and object touches or the duration of user misoperation is very short, therefore can reduce handheld device and be misunderstood the probability of lock.

3) judge whether user has carried out the clicking operation of preset times in the 3rd Preset Time.

When acting on force value on the display screen of handheld device, user meets first when pre-conditioned, handheld device control display screen shows release prompting control, in the 3rd Preset Time starting from current time, detect user's clicking operation, in the time determining that number of times that user carries out clicking operation is preset times, control display screen operation display interface, complete the release of handheld device.

It should be noted that, release prompting control can be various ways, for example: picture, icon, character or character string, as long as user as seen.Certainly,, in the time that handheld device control display screen shows release prompting control, judge whether that the mode of the predetermined registration operation that receives user is not limited to above-mentioned several.

In the time that handheld device control display screen shows input password prompt control, the mode that judges whether the predetermined registration operation that receives user has multiple, describes respectively below in conjunction with Fig. 2 and Fig. 3.

Referring to Fig. 2, the process flow diagram of the control method that Fig. 2 is another kind of handheld device disclosed by the invention.This control method comprises:

Step S21: under screen lock state, controlled pressure detecting unit detection display shields the force value of bearing, and obtains this force value.

Step S22: judge that whether force value meets first pre-conditioned, obtain the first judged result.

The implementation procedure of step S21 and step S22 is consistent with the step S11 in Fig. 1 and step S12, and specific implementation refers to above and describes, and does not repeat them here.

Step S23: meet first when pre-conditioned when the first judged result shows force value, control display screen and show input password prompt control.

Meet first when pre-conditioned when user acts on force value on handheld device display screen, its display screen of handheld device control shows input password prompt control.It should be noted that, this input password prompt control can be various ways, for example: picture, icon, character or character string, this input password prompt control is used for pointing out user to input password.

Step S24: controlled pressure detecting unit carries out pressure detection to display screen predetermined position in the 4th Preset Time, obtains multiple detected pressures values.

In the method, it is not by pressing the character keys realization in physical keyboard or dummy keyboard that user inputs password, but on display screen, carried out repeatedly pressing operation by user, certainly, each pressing operation acts on force value on display screen in corresponding preset range time, and just definite user has carried out predetermined registration operation.

In enforcement, user can carry out pressing operation in the optional position of display screen, but this just requires pressure sensing cell to carry out pressure detection to the Zone Full of display screen, and therefore pressure sensing cell need to arrange multiple pressure detection monomers, has improved accordingly the cost of pressure sensing cell.In order to reduce the cost of pressure sensing cell, in this method, be preferably user and carry out pressing operation at the predeterminated position of display screen, corresponding, as long as controlled pressure detecting unit carries out pressure detection to the predetermined position of display screen.

When handheld device control display screen shows after input password prompt control, if user will continue to carry out unlocking operation, need in the 4th Preset Time, carry out repeatedly pressing operation.Handheld device controlled pressure detecting unit carries out pressure detection to display screen predetermined position in the 4th Preset Time, just can obtain multiple detected pressures values.

Step S25: determine that respectively multiple detected pressures are worth residing pressure range.

Step S26: multiple pressure ranges are arranged as to pressure range set.

The pressure range prestoring by comparison, determines that respectively the multiple detected pressures that get are worth residing pressure range.Afterwards, the sequencing obtaining according to multiple detected pressures values, is arranged as pressure range set by multiple pressure ranges.

Step S27: judge that whether this pressure range set is consistent with the pressure range set prestoring, if consistent, perform step S28, otherwise, execution step S29.

Pre-stored in handheld device have a pressure range set, and the pressure range set that this prestores is set by the user.

Step S28: control display screen operation display interface.

In the time that pressure range set definite in step S26 is consistent with the pressure range set prestoring, determine the predetermined registration operation that receives user, control display screen operation display interface, complete the release of handheld device.

Step S29: extinguish display screen.

In the time that pressure range set definite in step S26 is consistent with the pressure range set prestoring, determine the predetermined registration operation that does not receive user, finish release flow process, extinguish display screen.

Introduce above-mentioned control method for clearer, describe in conjunction with example.

The pressure range set that user prestores is { [50,100], [120,170], [200,250] }, after handheld device control display screen shows input password prompt control, the operation that user presses display screen in the predetermined position of display screen in the 4th Preset Time.The force value that bear in the predeterminated position place of handheld device controlled pressure detecting unit detection display screen in the 4th Preset Time, if the force value obtaining according to time order and function order is respectively 60, 150 and 250, the pressure range prestoring by comparison, determine that the detected pressures getting is worth residing pressure range and is respectively [50, 100], [120, 170] and [200, 250], according to the sequencing that obtains each detected pressures value, multiple pressure ranges are sorted, pressure range set after sequence is { [50, 100], [120, 170], [200, 250] }, because the force value after this sequence is interval consistent with the pressure range set prestoring, therefore determine the predetermined registration operation that receives user, control display screen operation display interface, complete unlocking operation.

In the prior art, in order to improve the security of handheld device, the mode of employing is: after user presses the unlocking function key in handheld device, show dummy keyboard at display screen, input unlocking pin by user at dummy keyboard, or prompting user uses physical keyboard input unlocking pin.But there is drawback in this mode, in the time of the same unlocking pin of the long-term use of user, the virtual key place of the respective keys of physical keyboard and display screen is due to long-term use, can early there are wearing and tearing, disabled user is by limited number of time permutation and combination, just can determine the unlocking pin of handheld device, therefore, the mode security of existing release handheld device is lower.

And in the control method of the disclosed handheld device of Fig. 2 of the present invention, using the force value that in the display screen of handheld device, predetermined position is born as the judgement foundation that finally completes release, only have user in the 4th Preset Time, to carry out the pressing operation of preset times, and the force value that each pressing operation produces at display screen all, in the time of default pressure range, just can complete the release of handheld device.Even if handheld device is in long-term use procedure, there are wearing and tearing in a certain position of display screen, disabled user also cannot therefrom obtain any prompting of press pressure, therefore based on the above-mentioned disclosed control method of the present invention, in simplified solution latching operation, also further improve the security of equipment.

Referring to Fig. 3, the process flow diagram of the control method that Fig. 3 is another kind of handheld device disclosed by the invention.This control method comprises:
