Preferred embodiment
The power consumption control method of prior art is not all considered to use human factor on the impact of LCD power consumption.Such as, after some touch control operation of user (waiting for page display, start-up routine etc. when batch deleting short message and file, web page browsing) occurs, need to wait for that short time could show result, backlight does not need to be in normal brightness in fact during this period of time.In addition, by timeout mechanism, the method judges whether user also can use mobile phone, in order to not reduce Consumer's Experience, this timeout value is minimum all more than 15 seconds, that is, after each user uses mobile phone, the LCD power consumption that all additionally will consume at least 15 seconds realizes automatically from using state to the switching of not using state, and therefore this proposes instructions for use to user, user initiatively must close LCD when not using mobile phone, otherwise will produce this energy consumption in vain.
In fact, by carrying out statistical analysis to the data of user's touch control operation, can infer which type of operator scheme user is at present, then according to this operator scheme, suitable adjustment be carried out to the backlight of LCD, instead of as existing method, remain a kind of constant brightness.In addition, by the data analysis to touch control operation, also can infer whether user does not re-use mobile phone, now just can close LCD as early as possible, user is not needed initiatively to close or realized by traditional timeout mechanism, thus user-friendly or reduce the LCD energy consumption of mobile phone from using state automatically switches to not using state process.
How statistical analysis is carried out to user's touch control operation? because the UI interface of modern procedures all follows modularization principle, each control namely on interface has specific function.This just means that user carries out same touch control operation at every turn on same interface control, internal system process and user should be the same to the feedback of system result, that is for each touch control operation, system processing time and feedback (namely according to system result perform new touch control operation) the time sum of user to system result are regular, are fixing substantially.The statistics of above analyzing body present touch-control input data is exactly: the touch control operation carrying out certain on same interface control, then the time interval between the ensuing next touch control operation of user and this touch control operation is constant substantially.By analyzing the rule in these time intervals, just can obtain some behavior patterns of user, such as waiting for completing (webpage loads as waited for) of time-consuming operation, or in reading or viewing video or browser document etc. (as seeing novel), information just can the backlight etc. of dynamic conditioning LCD accordingly, reaches the object reducing LCD power consumption further.
The flow process of this preferred embodiment is as follows: obtain the type of the current touch control operation of user and the interface control of this operation correspondence; Go to inquire about caluclate table according to action type and corresponding interface control, dope the time interval of user's touch control operation next time according to caluclate table; According to the historical record of user's touch control operation, draw the behavior pattern that user is current; According to current input time, upgrade data corresponding to touch control operation last time in caluclate table; According to behavior pattern and input interval predicted time, power consumption control is carried out to LCD.
Be described for android mobile phone below.The method of the present embodiment mainly realizes in this class of ViewRootImpl and PowerManagerService of android.In android system, all user's touch control operations are all received by this class of ViewRootImpl and are distributed to concrete control process.Wherein, can use ViewID domain identifier control, namely user carries out touch control operation for which control; All_counters have recorded the total degree that user carries out touch control operation on this control; Success_counters have recorded the successful number of times of system prediction; Expect_value records the statistical value of touch control operation spacing value.
For the prediction of user behavior pattern, a kind of simple prediction algorithm is had to be described below: (1) declines if this incoming event is KEY_DOWN(key point) event, then illustrate it is click, and prediction present event and next event interval greater than some threshold values when, then think that now user behavior pattern is standby mode; (2) lift if this incoming event is MOTION_UP() event, and last time, incoming event was that MOTION_DOWN(declines), then this is a click gesture, and prediction present event and next event interval greater than some threshold values when, think that now user behavior pattern is standby mode; (3) lift if this incoming event is MOTION_UP() event, and last time, incoming event was that MOTION_MOVE(moves), then this is a slip gesture, then think that now user behavior pattern browses (or reading) pattern; (4) any situation in addition, all nonrecognition, control not effect to control, need not process.
Based on said method, this preferred embodiment additionally provides a kind of closing control to LCD screen, its prediction algorithm is: after beginning caluclate table starts to learn various data, also add up the spacing value of any twice touch-control event, what selection spacing value was maximum is limiting threshold value, when user still touch control operation does not occur when this limiting threshold value arrives, then predict that user is in and terminate to use this behavior pattern of mobile phone, perform the operation of lock-screen.
Because mobile terminal can identify wait, browses (reading), terminate to use mobile phone three behaviors pattern, so, according to these behavior patterns, the power consumption control method that corresponding execution is different, specific as follows:
If terminate to use handset mode, at once that screen is dimmed, and point out user to prepare to close LCD, in special time (as 2 seconds), user is without any operation, and this prediction of customer acceptance system is described, then, after special time arrives, close LCD; Otherwise, LCD is returned to normal operating brightness.
If standby mode, according to timeout value (timeout value, the i.e. above-mentioned preset touch time interval threshold value mentioned) adjustment, first LCD brightness is dimmed, then progressively heightens brightness, until when timeout time period Mo luminance recovery to normal brightness.The step value of the degree dimmed and recovery brightness can be determined according to Consumer's Experience, ensures that user's visual experience is good as far as possible;
If reading model, within this timeout time period, LCD brightness is progressively dimmed, the degree dimmed and the step value dimmed are determined according to Consumer's Experience, ensure that user is not aware of brightness dimmed as far as possible.
Below in conjunction with Fig. 7, said method is described in detail.The flow process of Fig. 7 comprises step S702 to step S722.
Step S702, detects new touch control operation input.
Step S704, judges whether this operation is the operation that gesture terminates.Wherein, judging whether gesture terminates also is to determine current behavior pattern.If so, then perform step S706, otherwise perform S714.
Step S706, finds the ViewID of the control that this touch control operation is corresponding, and root ViewID goes to look into caluclate table, if found, according to the value of Success_counters/All_counters, obtains a statistical probability value.
Step S708, judges whether statistical probability value is greater than predetermined probabilities value.If so, then open power consumption control process, perform step S710, otherwise, perform step S714.
Step S710, the value of taking out its Expect_value corresponding in caluclate table is as the predicted value at next touch control operation and this touch control operation interval.
Step S712, determines current behavior pattern.Just carry out after the predicted value determining next touch control operation and this touch control operation interval in the present embodiment, certainly, if necessary, after determining the operation that gesture terminates, just can carry out the judgement of behavior pattern.
Step S714, according to the time that last time, touch control operation occurred of record, calculates the time difference of twice touch control operation generation.
Step S716, judges whether the above-mentioned time difference is greater than predetermined threshold.If so, then step S718 is performed, otherwise, perform step S722.
Step S718, according to record last time touch control operation institute for ViewID, find in caluclate table correspondence list item, the value in its Success_counters territory and All_counters territory is added 1; If there is no corresponding list item, then in table, add a list item, wherein ViewID equal to record last time touch control operation for ViewID, the value of the value in Success_counters territory and All_counters territory equals 1.
Step S720, records this touch control operation type and time as basis (i.e. last time) touch control operation type next time and time, waits for the arrival of touch control operation next time.
Step S722, according to record last time touch control operation institute for ViewID, find in caluclate table correspondence list item, the value in its All_counters territory is added 1.
Although be example object, disclose the preferred embodiments of the present invention, it is also possible for those skilled in the art will recognize various improvement, increase and replacement, and therefore, scope of the present invention should be not limited to above-described embodiment.
