Description

The method of the screen rotation pattern automatically controlling mobile terminal is bounced based on user

Technical field

The present invention relates to screen rotation pattern, more specifically, the present invention relates to the method for bouncing the screen rotation pattern automatically controlling mobile terminal based on user.

Background technology

The mobile terminal that horizontal/vertical screen handoff technique refers to such as mobile phone in the horizontal direction and vertical direction place between when changing, screen picture automatic rotation is to meet the visual demand of user.The operating system of existing mobile terminal (such as, android system) support that automatic switchover horizontal/vertical screen switches, realize principle as follows: the operating system of mobile terminal has the interface of gravity sensor, use the mobile terminal of operating system all to have gravity sensor.This sensor can the acceleration of gravity data X of continuous reporting system, Y, Z.The operating system of such as Android passes through the state at formulae discovery mobile terminal, with reference to figure 1a.Fig. 1 a shows the acceleration of gravity direction of the X, Y, Z axis of mobile terminal under standing state.

This algorithm in most of the cases can solve the problem that mobile terminal horizontal/vertical screen switches.Detailed algorithm in the operating system situation of Android can illustrate with reference to the official of google: http://developer.android.com/reference/android/hardware/SensorM anager.html.

But when user lies low or lie on one's side, the acceleration of gravity of mobile terminal X-axis and Y-axis will operation mistake.Such as, when seeing mobile terminal under the condition of lying on one's side, X-axis is different from gravity value when seeing mobile terminal when people stands with the gravity value of Y-axis.The mobile terminal angle value calculated by X, Y-axis differs 90 degree with mobile terminal angle value when standing.Therefore, when user wants to use perpendicular screen to see mobile terminal, mobile terminal has switched to horizontal screen pattern.Such user is difficult to use mobile terminal satisfactorily.With reference to figure 1b.Fig. 1 b shows the acceleration of gravity direction of the X, Y, Z axis of mobile terminal under the state of lying on one's side.

For this problem, the existing solution of Android is: arrange in project at Android and arrange, forbidding horizontal/vertical screen handoff functionality.Like this, when user lies low, mobile terminal would not automatically switch horizontal/vertical screen state, and user can not cause operation inconvenience because of the automatic switchover of screen.

But the shortcoming that prior art exists is: when user thinks toggle screen modes, just must first enable horizontal/vertical screen handoff functionality, then by rotation of mobile terminal, when mobile terminal is in the horizontal/vertical screen state of user oneself hope, then lock-screen.Mobile terminal screen is placed in by this operation the state that user wishes, complex operation.For mobile phone users, all wish that operation is as far as possible easy, loaded down with trivial details operation is for significantly reducing Consumer's Experience.With reference to android system source code: http:// source.android.com.

Therefore, need a kind of method and system controlling mobile terminal horizontal/vertical screen display mode, to solve the problems such as erroneous judgement detection of the prior art and loaded down with trivial details manual operation.

Summary of the invention

The object of the invention is to the shortcoming overcoming prior art, a kind of method of bouncing the screen rotation pattern automatically controlling mobile terminal based on user is provided.

According to one embodiment of present invention, provide a kind of method of bouncing the screen rotation pattern automatically controlling mobile terminal based on user, comprising: monitoring users bounces event; Whether event of bouncing described in judgement is bounce event twice; If described in the event of bouncing be bounce event twice, then enable screen rotation function; And by the screen rotation of described mobile terminal to assigned direction.

Embodiment

A kind of method of bouncing the screen rotation pattern automatically controlling mobile terminal based on user is disclosed according to embodiments of the invention.In the following description, for illustrative purposes, multiple detail has been set forth to provide the complete understanding to embodiments of the invention.But it is evident that for those skilled in the art, embodiments of the invention can realize when not having these details.

The application bounces the action of mobile terminal by monitoring, terminal screen in rotary moving is to specified location in user.Mobile terminal screen under any state, can be switched to the state of expectation by user fast.Such as, user can avoid under lying down or lying on one's side state, because the direction of mobile terminal gravity axis is different, causes the problem that the poor direction of rotation of mobile terminal screen is true.Or user can when not wishing that user rotates, forbidding screen rotation function.

Such as, Android operation system is the operating system be erected on Linux and JAVA virtual machine, and whole system tension management operates in SystemServer process, by multiple different service and administrative class management system.With following table 1 show the application mainly need use service and system tool class.

Table 1

The application is the data of the gravity sensor by monitoring mobile terminal, judges that mobile terminal bounces action.Quick lock in screen is provided anyhow to switch, quick turnover screen, for user provides excellent Consumer's Experience.

In the android system of mobile terminal, the framework of sensor is service layer, hardware device level and driving layer from top to bottom successively, acceleration transducer or gyrostatic data all obtain at driving layer, then upwards transmit successively, are finally delivered to service layer and process.In the prior art, system service and upper layer application need the event returned by monitoring SensorService, can obtain corresponding sensing data.

Fig. 2 shows the Android sensing data processing flow chart according to technical scheme of the present invention.As shown in Figure 2, according to the technical scheme of the application, based on the data of bouncing action about user that service layer reads, utilize algorithm illustrated in the application automatically to control the screen rotation pattern of mobile terminal, add the service of the technical scheme according to the application at Android SystemServer.After system starts, this service automatically starts and monitors the sensing data of SensorService, and does not need by monitoring the event that returns of SensorService.Simultaneously this service adds blocker at SensorService layer, tackles other if desired and serves monitoring behavior to acceleration transducer and gyro data.

Acceleration transducer can measure the component size of current acceleration of gravity on X, Y, Z axis direction.When user bounces mobile terminal from certain direction time, significantly can change X, Y, the sensor values in Z-direction, android system can register audiomonitor in SensorService, monitors these changes of sensor.

Particularly, by the numerical value change of monitoring users gravity sensor, can judge that user's bounces behavior.Such as, behavior account form is bounced as follows: when the sensor acceleration information listening to such as X-axis and Y-axis occurs that high-amplitude changes at short notice, then return recent average level rapidly, then can judge that user bounces mobile terminal.Amplitude of variation is as shown in following table 2 and table 3:

User's right-to-left bounces on the right side of mobile terminal.

Table 3

As can be seen from upper table 2 and table 3, there is the unexpected fluctuation of short time in the sensing data of monitoring.When meet below two conditions time, then can think on this axis of orientation, user has bounced mobile terminal once.

(1): have the difference of twice sensor values and last sensor values in 1 second higher than reservation threshold (threshold values can be different according to the situation of different mobile terminal).

(2): sensor values is attributed to mean value after Rapid Variable Design.

Computing formula is as follows:

$|(X_n-X_{n-1})-\left(\underset{k=1}{\overset{n}{\mathrm{\Σ}}}{X}_k\right)/n|>\max$

$|(X_p-X_{p-1})-\left(\underset{k=1}{\overset{n}{\mathrm{\Σ}}}{X}_k\right)/n|>\max$

$|\left(\underset{k=1}{\overset{n}{\mathrm{\&Sigma;}}}{X}_k\right)/n-\left(\underset{k=p}{\overset{p+10}{\mathrm{\&Sigma;}}}{X}_k\right)/n|<\min$

Wherein, X _nrepresent the N time sensing data, X _n-1represent X _nlast sensing data.X _krepresent the X of sensor _nbefore kth time sensing data (k value can be debugged according to actual hardware) Max represent and bounce event threshold values, exceed this value representative of consumer and bounce a mobile phone.Max can adjust according to the hardware data of different mobile phone.X _pand X _nimplication is identical, is and X _ninterval is sensor values within one second.Corresponding table 3 data, X _nrepresent y3, X _prepresent y5.

In addition, if occurred continuously bouncing event twice in 2 seconds or 3 seconds, the change direction of sensor values is identical simultaneously, is all become large or diminish, then can think that user doublely bounces event.If repeatedly bouncing of user three times or more detected in 2 or 3 seconds, but the direction of sensor is different, then can judge that user is rocking mobile terminal, therefore as bouncing event.

When listening to after user bounces event, event being bounced for different, can control Android Framework layer identification code be passed through, the option of the setting of amendment mobile terminal, so that forbidding or enable the screen rotation function of mobile terminal.

Such as, event is bounced for single, the screen rotation function of forbidding mobile terminal, thus do not perform the operation of any roller blind.If event of bouncing is not single bounce event, then enable screen rotation function.Bounce event for twice, action is bounced to up and down double of user to mobile terminal and makes response, mobile terminal screen is rotated to the direction that user specifies.Described twice event of bouncing comprises from up to down, bottom-up, at least one from left to right and in right-to-left.Such as, if user bounces mobile terminal from left to right, then mobile terminal performs the operation of Rotation screen left; If user's right-to-left bounces mobile terminal, then mobile terminal performs the operation of Rotation screen to the right; If user from up to down bounces mobile terminal, then mobile terminal performs the operation rotating up screen; And if user is bottom-up bounces mobile terminal, then mobile terminal performs the operation being rotated down screen.For three times or more repeatedly bounce event, mobile terminal forbidding screen rotation function, that is, does not perform screen rotation operation.

Fig. 3 shows the process flow diagram of the method 300 of bouncing automatic control flow curtain rotary mode according to an embodiment of the invention based on user.As shown in Figure 3, in step 301, mobile terminal monitoring users bounces event.In step 302, judge whether event of bouncing is that single bounces event.If so, then in step 303, mobile terminal forbidding screen rotation function.If not, then in step 304, judge event of bouncing be whether three times or more bounce event.If so, then in step 305, mobile terminal forbidding screen rotation function.If not, then within step 306, judge whether event of bouncing is bounce event twice.If so, then in step 307, mobile terminal enables screen rotation function.Then, in step 308, bounce event based on two, mobile terminal screen is rotated to the direction that user specifies.Then, the method 300 terminates.

In the technical scheme of the application, propose the optimization to the automatic roller blind function of existing Android mobile terminal.Under technical scheme of the present invention not only solves the abnomal condition being used in and such as lying and lie on one's side, due to the change of mobile terminal gravity axis, mobile terminal can not the problem of correct roller blind, and automatically can control the roller blind of mobile terminal under any state under the normal condition of such as standing according to the needs of user.Technical scheme of the present invention uses gravity sensor to classify to the action that user bounces, but and does not rely on gravity sensor to control the screen rotation pattern of mobile terminal.And because roller blind function is one of the most frequently used several functions of mobile terminal, this scheme can improve the Consumer's Experience of Android mobile terminal significantly.That is, according to technical scheme of the present invention, user just can obtain extra layout pattern by simple action, and period does not need to operate any interface element or entity button, thus the friendly of effective lifting mobile terminal and experience satisfaction.

Above-described embodiment is only the preferred embodiments of the present invention, is not limited to the present invention.It will be apparent for a person skilled in the art that without departing from the spirit and scope of the present invention, various amendment and change can be carried out to embodiments of the invention.Therefore, the invention is intended to contain all amendments within the scope of the present invention as defined by the appended claims of falling into or modification.
