Abstract
The invention provides a high-accuracy screen touch response method. The method comprises the following steps: preferably judging whether mobile intelligent equipment is in an approaching state or not when screen touch operation is detected; if not, indicating that a proximity sensor is exposed out of a pocket, and not responding to the screen touch operation; detecting whether the proximity value of the proximity sensor (when the proximity value is larger, the distance of a closest object detected by the proximity sensor is smaller) is in a process of changing from large to small or not; if so, judging that the mobile intelligent equipment is getting far away from a certain object or in a process of being taken out of the pocket at high possibility without responding to any screen touch operation. By using the method, error operation can be avoided effectively.
Description
Technical field
The present invention relates to intelligent movable equipment technical field, the touch screen response method that particularly a kind of accuracy is high.The method, by setting up functional module construction, is completed by computer program instructions control computer system.
Background technology
Along with the development of electronic technology, the intelligent movable equipment such as mobile phone, e-book are popularized widely.Intelligent movable equipment, as a kind of portable equipment of miniaturization, often can be placed in the pocket bag that trouser pocket, pocket etc. are next to the skin in daily life, and pocket bag and intelligent movable equipment room inevitably can exist friction, particularly in the process of pocket bag motion.Again because the touch control operation (screen rubs) that intelligent movable equipment relies on screen more is now realized input information or control, therefore the friction of pocket bag and intelligent movable equipment may allow the erroneous judgement of intelligent movable equipment touch input, thereby cause intelligent movable equipment generation maloperation, even, even if intelligent movable equipment is realized in pocket bag in dormant state by manual or some auto sleep programs, but because the friction of intelligent movable equipment and pocket bag is comparatively large-area friction, therefore very likely in friction process false triggering wake actions (wake actions refers to the default certain gestures operational motion carrying out on screen, such as draw a circle, or draw a triangle, an intelligent movable equipment may have multiple wake actions, in the time that intelligent movable recognition of devices is carried out wake actions to user on touch-screen, waken system and enter application corresponding to this wake actions) cause intelligent movable equipment by false wake-up, the result of false wake-up is to cause more nothing operation to be moved smart machine receive and respond.
For the problems referred to above, whether the intelligent movable equipment that the proximity transducer that at present part intelligent movable equipment carries with it judges in pocket bag, avoid maloperation with this.First adopt specific dormancy program (if publication number is the method and apparatus of the disclosed a kind of intelligent movable equipment auto sleep of patent documentation of CN 103516901A) to judge that intelligent movable equipment is whether in pocket bag, if so, make intelligent movable equipment enter dormant state.Intelligent movable equipment is in dormant state the detected value of approaching of auto-real-time monitoring proximity transducer subsequently, be less than preset value if approach value, judge that now intelligent movable equipment is still in pocket bag, now any touch screen operation is not all responded, only have in the time that approaching value is less than preset value, just judge that now intelligent movable equipment still in pocket bag, now just can respond touch screen operation and further judge whether this operation is wake operation.This method can address the above problem preferably in theory, but find in actual applications, due to reasons such as the structures of intelligent movable equipment, proximity transducer can not be arranged on the center of equipment, generally be mounted in the fringe region of intelligent movable equipment, in the process of therefore user, intelligent movable equipment being taken out from pocket bag, very likely the proximity transducer of intelligent movable equipment is exposed in pocket bag outside, and the major part of intelligent movable equipment (the particularly major part of touch screen) is still in pocket bag, because intelligent movable equipment is under the state moving outside pocket bag from pocket bag, now its still this part in pocket bag be more prone to rub with pocket bag, cause producing maloperation, or even false wake-up.And along with the touch screen of intelligent movable equipment becomes increasing, it is more and more frequent that the generation of above-mentioned this situation also becomes, therefore need a kind of intelligent movable equipment that can solve targetedly badly in the method that shifts out the maloperation problem in pocket bag process.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art and the touch screen response method that a kind of accuracy is high is provided, the method can effectively prevent that intelligent movable equipment from, shifting out the problem that shifts to an earlier date the exposed false-touch prevention mechanism failure causing in pocket bag process due to proximity transducer, can solve intelligent movable equipment targetedly in the method that shifts out the maloperation problem in pocket bag process.
Mentality of designing of the present invention is as follows: because this maloperation occurs in the process that intelligent movable equipment shifts out pocket bag, judge intelligent movable equipment whether under the state in shifting out as long as therefore can detect from pocket bag, and do not respond any operation and can effectively avoid the maloperation in this stage in state lower time of shifting out when intelligent movable equipment from pocket bag; But, in intelligent movable equipment, detection for its motion state generally depends on gyro sensor or acceleration transducer, is only to judge whether intelligent movable equipment is difficult to judge the whether state in shifting out from pocket bag of intelligent movable equipment in mobile status and significantly relying on two kinds of sensors.Therefore one of key of the present invention is to find and a kind ofly can judges the whether determination methods in the state in shifting out of intelligent movable equipment from pocket bag.
Object of the present invention is achieved through the following technical solutions:

Anti-mobile false touch step: obtain the value of approaching that proximity transducer detects, the described value of approaching is larger means that the distance value of the immediate object that detects to proximity transducer is less, judge that this approaches value whether in variation tendency from large to small, if so, does not allow to respond touch screen and operates.
Wherein, described anti-mobile false touch step comprises:
Variation tendency calculation procedure: periodically obtain and approach value, the value of approaching of once obtaining before the value of approaching of instantly obtaining is deducted approaches changing value to obtain;
Mobile trend determining step: judgement approaches changing value and whether is less than default trend changing value, if so, judgement approaches value in variation tendency from large to small, and wherein, described default trend changing value is less than zero.(this place content is the technology contents that writer expands, and the technology of asking confirms that whether this expansion is feasible)
Wherein, the described anti-false touch step that approaches comprises and approaches state determining step: obtain the value of approaching of proximity transducer and judge that whether it is greater than the first default value that approaches, and if so, judges now in approaching state.
Preferably, described anti-mobile false touch step comprises that response condition resets step: approach value in variation tendency from large to small as judged, obtain the value of approaching of proximity transducer and judge whether it is greater than the second default value that approaches, if not, allow the operation of response touch screen, if so the value of approaching of, again obtaining proximity transducer after the latent period time is to judge whether it is less than the second default value that approaches.
Wherein, method also comprises wake-up step: judge that whether intelligent movable equipment is in dormant state, if so,, in the time touch screen operation being detected, judge whether described touch screen operation is wake actions, if, wake intelligent movable equipment up, if not, ignore this touch screen operation, the wake operation action that described touch screen operation is intelligent movable equipment, described wake operation action is for waking intelligent movable equipment up from dormant state.
Beneficial effect of the present invention: the invention provides the touch screen response method that a kind of accuracy is high, the method preferentially judges that whether intelligent movable equipment is in approaching state in the time touch screen operation being detected, if not, illustrate that proximity transducer is exposed to outside pocket bag, now wouldn't respond touch screen operation, but whether the value of approaching (distance that approaches the immediate object that detects of the larger proximity transducer of value is less) that detects proximity transducer is in change procedure from large to small, if, can judge that intelligent movable equipment is now away from jobbie, also very likely in the process in being taken out by pocket bag, now do not respond any touch screen operation, can effectively avoid maloperation.
Brief description of the drawings
The invention will be further described to utilize accompanying drawing, but embodiment in accompanying drawing does not form any limitation of the invention, for those of ordinary skill in the art, is not paying under the prerequisite of creative work, can also obtain according to the following drawings other accompanying drawing.
Fig. 1 is the schematic flow sheet of the embodiment 1 of the touch screen response method that a kind of accuracy of the present invention is high.
Embodiment
The invention will be further described with the following Examples.
embodiment 1
One of embodiment of the touch screen response method that a kind of accuracy of the present invention is high, comprising:
Steps A: intelligent movable equipment enters dormant state, opens wake actions recognition function, reduces touch screen sensitivity.Wake actions recognition function is used for identifying whether touch screen operation is wake actions, is the function of waking intelligent movable equipment necessity up; Reducing touch screen sensitivity is because the touch control operation under dormant state mostly is maloperation (the subjective operation of non-user), therefore the reduction of sensitivity both can reduce the generation (can be left in the basket when touch action is smaller) of maloperation, also can reduce energy consumption simultaneously, particularly, the method of desensitization can be realized by the parameter of adjusting in sensitivity register, belong to this area routine techniques means, do not repeat them here.
Step B: start proximity transducer, obtain the value of approaching that proximity transducer detects, judge whether this value of approaching is greater than the first preset value, if so, judge that intelligent movable equipment, now in approaching state, closes touch screen response function, any touch screen operation is not responded, if not, judge now that at least proximity transducer, by exposed, is adjusted to step C further to judge.It should be noted that the value of approaching is wherein actually the infrared light intensity coefficient that proximity transducer detects, because it is a pair of infrared emission-receiver that proximity transducer is said in essence, it judges the distance value between its current and its immediate object by the intensity that receives its infrared light of launching and be reflected back, the infrared light intensity receiving is stronger, represents that the distance between itself and immediate object is less.Certainly, in practical programs, this value of approaching can be also other parameters after optimised, as long as this parameter can embody the distance value between proximity transducer and its immediate object, in the present invention for convenience, defining this, to approach value be that distance value between proximity transducer and its immediate object is inversely proportional to, the value of approaching is larger, and the distance between proximity transducer and its immediate object is less.
The value of approaching of once obtaining before the value of approaching deducts approaches changing value to obtain.Certainly, on the basis of this thinking, can also do further optimization to approaching the calculating of changing value, for example, approach in variation stack and be averaging etc. multiple, the non-emphasis of the present invention of optimization of specific algorithm, is not repeated herein.
Step D: judgement approaches changing value and whether is less than default trend changing value, if so, judgement approaches value in variation tendency from large to small, [h1] now closes touch screen response function, any touch screen operation is not responded, if not, jump to step e.It should be noted that, described default trend changing value is less than zero, only has the changing value of approaching to be less than zero and could illustrate that approaching value is in gradually and diminishes.The size of certainly default trend changing value can be adjusted flexibly, can adjust the method sensitivity during away from object to intelligent movable equipment by adjusting the size of default trend changing value, in some occasion, intelligent movable equipment also has away from the situation of object and occurs, but the change intensity that approaches value under different occasions is different, leave in the process of pocket bag at intelligent movable equipment, the variation that approaches value is comparatively strong, and make discovery from observation, connect at comparatively strong occasion (smart machine ambient environmental conditions the changes fast) smart machine of the approaching value variation of major part the touch screen operation detecting and mostly be maloperation, therefore can make the method more effectively prevent maloperation and can not impact user's normal running by the default trend changing value of reasonable adjustment.
Step e: detect in real time touch screen operation, judge and detect whether described touch screen operation is wake actions, if so, wakes intelligent movable equipment up and enters into application corresponding to this wake actions, if not, ignore this touch screen operation.
It should be noted that, what the present embodiment provided is the touch screen response method under dormant state at intelligent movable equipment, this is generally all can be in dormant state in pocket bag owing to working as smart machine in practical application, but, if intelligent movable equipment is in non-dormant state, can only carry out step B, C, the D of the present embodiment, it can solve intelligent movable equipment equally in the maloperation problem shifting out in pocket bag process.
Compared with prior art, this method is non-in approaching state at detection intelligent movable equipment, wouldn't respond touch screen operation, but whether the value of approaching that detects proximity transducer is (in change procedure from large to small, if so, can judge that intelligent movable equipment is now away from jobbie, very likely in the process in being taken out by pocket bag, now do not respond any touch screen operation, thereby effectively avoid maloperation.
embodiment 2
Steps A: intelligent movable equipment enters dormant state, opens wake actions recognition function, reduces touch screen sensitivity.
Step B: when touch screen operation detected, obtain the value of approaching that proximity transducer detects, judge whether this value of approaching is greater than the first preset value, if so, judge that intelligent movable equipment, now in approaching state, closes touch screen response function, any touch screen operation is not responded, if not, judge now that at least proximity transducer, by exposed, is adjusted to step C further to judge.
Step C: periodically obtain and approach value, the value of approaching of once obtaining before the value of approaching of instantly obtaining is deducted approaches changing value to obtain.
Step D: judgement approaches changing value and whether is less than default trend changing value, if so, judgement approaches value in variation tendency from large to small, now close touch screen response function, any touch screen operation do not responded and turned to step e, if not, jumping to step F.
Step e: obtain the value of approaching of proximity transducer and judge whether it is greater than the second default value that approaches, if not, open touch screen response function, if, after the latent period time, again obtain the value of approaching of proximity transducer to judge whether it is greater than the second default value that approaches, just open touch screen response function until the value of approaching of proximity transducer is less than the second default value that approaches, in the time touch screen operation being detected, jump to step F.The second preset value is less than the first preset value.
Step F: detect in real time touch screen operation, judge whether described touch screen operation is wake actions, if so, wakes intelligent movable equipment up and enters into application corresponding to this wake actions, if not, ignore this touch screen operation.
Embodiment 2 is with the difference of embodiment 1: embodiment 1 is after detecting that approaching value is in variation tendency from large to small, only have the touch screen operation detecting when by the time intelligent movable equipment stops mobile (approaching value no longer changes) just to be responded, embodiment 2 is that to approach value requirement after variation tendency from large to small must be that distance between proximity transducer and its immediate object reaches touch screen that after certain distance, (approaching value is less than the second preset value) detects and operates ability and responded determining.
The method providing herein, all or part of step wherein can, by setting up functional module construction, be completed by computer program instructions control computer system.These computer program instructions are stored in computer-readable recording medium.
Finally should be noted that; above embodiment is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; although the present invention has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement technical scheme of the present invention, and not depart from essence and the scope of technical solution of the present invention.
