The embodiment of the present invention is carried out Real-time Collection to the relevant operational parameter of terminal touch screen in the communication process of terminal, and by each operating parameter collecting and default switching condition are compared, according to comparative result to judge the current location status of whether pressing close to ear in user of described terminal, thereby need in terminal, not place the screen that automatically goes out that proximity transducer can be realized terminal in communication process, reduce the hardware production cost of terminal.
Embodiment of the method
Fig. 1 shows the realization flow of the terminal screen control method that first embodiment of the invention provides, and details are as follows:
In step S101, when terminal is during in talking state, obtain the current operating parameter of described terminal touch screen, described operating parameter is parameter relevant to touch operation on described touch-screen.
Specifically, by terminal multi-mode operation parameter is now detected and gathered, for whether pressing close to the location status of ear by multi-mode operation parameter in user comprehensively to judge terminal.
As one embodiment of the present of invention, the operating parameter of described touch-screen comprises the first operating parameter, and described the first operating parameter includes but not limited to touch screen position and the touch screen area of terminal.Above-mentioned the first operating parameter must satisfied operating parameter for terminal being switched to the screen state that goes out institute, and scarce one likely can not judge the location status of terminal.
Further, as an alternative embodiment of the invention, operating parameter can also comprise the second operating parameter, and described the second operating parameter includes but not limited at least one in touch screen pressure, touch screen shape or gravity sensing state.Above-mentioned the second operating parameter, for terminal being switched to the optional operating parameter of screen state institute that goes out, by above-mentioned one or more operating parameter is judged, can further improve the judgement precision of terminal location state.
In step S102, when the current operating parameter of described terminal touch screen meets default switching condition, described terminal touch screen is switched to the screen state that goes out.
Optionally, as one embodiment of the present of invention, because user is in the process of utilizing terminal to converse, can carry out terminal to press close to the call action of ear, therefore, when user carries out this call action, corresponding operating parameter is respectively in following state:
Touch screen position: be a part of region of terminal near loudspeaker, only have ear is pressed close near the region of terminal horn and just can be heard the other side's sound; The difference that particular location can need according to precision presets.
Touch screen area: in a certain preset range,, because in communication process, by face or ear touch screen, the touch screen area while using finger touch screen during now than operating terminal is larger; Concrete scope can preset according to the difference of accuracy requirement.
Touch screen pressure: in a certain preset range, because in communication process, by face or ear touch screen, during now than operating terminal,, with finger touch screen, its touch screen pressure is less; Concrete scope can preset according to the difference of accuracy requirement.
Touch screen shape: irregular figure, and the touch screen shape that finger produces during touch screen is obviously a point or the subcircular of rule comparatively; Concrete area figure can be realized according to the sample of prior typing definite shape.
Gravity sensing state: in a certain angular range, existing terminal possesses gravity sensing function mostly, and because user is vertically attached to terminal by face side or ear, therefore now terminal answers relative level line to present certain angle; Concrete angular range can preset according to the difference of accuracy requirement.
In the present embodiment, by the aforesaid operations parameter collecting and default switching condition are compared to the location status that judges that terminal is current:
Particularly, when described operating parameter only comprises the first operating parameter, default switching condition is accordingly: described in each, first degree of correlation of its corresponding preset range of the first operating parameter is all not less than its corresponding the first predetermined threshold value.Described predetermined threshold value is the predetermined threshold value of the degree of correlation.
When described operating parameter comprises the first operating parameter and the second operating parameter, corresponding default switching condition is except first degree of correlation of its corresponding preset range of the first operating parameter described in each is all not less than its corresponding first predetermined threshold value, also needs to meet first degree of correlation of its corresponding preset range of the second operating parameter described at least one and is not less than its corresponding the first predetermined threshold value.
For above-mentioned switching condition, for example, by being the default corresponding scope of each operating parameter (touch screen area can in a numerical range), the terminal location state of conversing and moving for describing user, and by the operating parameter detecting and corresponding preset range are compared, get respectively first degree of correlation of its corresponding preset range of operating parameter described in each.

In the present embodiment, first degree of correlation for its corresponding preset range of operating parameter described in each, corresponding the first predetermined threshold value all can be set, when in described the first operating parameter, first degree of correlation of each operating parameter is all not less than its corresponding first predetermined threshold value, represent that now terminal has the larger location status that may receive calls in pressing close to ear, carry out the action that touch-screen is switched to the screen state that goes out.Optionally, described the second operating parameter is mainly used to promote judgement precision, when first degree of correlation of at least one operating parameter is all not less than its corresponding first predetermined threshold value in described the second operating parameter, switches the screen state that goes out, and can promote precision.
Described each operating parameter and corresponding relatedness computation formula thereof or form, corresponding the first predetermined threshold value all can be kept in described terminal, for processor, when calculating and judging, call.
Thus, by above-mentioned steps, without proximity transducer, can utilize touch screen to respond to the action that user is pressed close to ear or face by terminal judges, thereby in user's communication process, to the terminal screen that automatically goes out, saved the hardware cost of terminal.
Optional in addition, because user is in communication process, certain operations parameter is to keep changeless, for example, during call, terminal can not keep same vertical angle, but can in certain angle, slightly rock, therefore for gravity sensing state, may have a bit of time not in preset range, now, if directly the state of terminal screen is controlled according to real-time testing result, likely produce the phenomenon of the frequent switch of screen, do not reach the effect of energy saving, also therefore shortened on the contrary the serviceable life of terminal screen.Therefore, in order to improve manipulation accuracy, can meet after described default switching condition in first degree of correlation or second degree of correlation of the described operating parameter of judgement, after the full certain hour of meter, be switched to again the action of the screen state that goes out, to reduce operate miss.Specific implementation can be: when the current operating parameter of described terminal touch screen meets default switching condition, start timing and obtain default delay switching time; When the operating parameter of full described delay switching time of described chronoscope and described touch-screen still meets described default decision condition, described terminal touch screen is switched to the screen state that goes out.
In addition, as the second embodiment of the present invention, because each user uses the custom of terminal different, in order further to improve the levels of precision to terminal location state judged result, can in the process of terminal, set up and the exclusive tcs database of optimizing user progressively by using user, and by operating parameter further with database in related parameter values compare, with control terminal screen in corresponding state.Now, default switching condition is also included as second degree of correlation of the first operating parameter described in each and is all not less than its corresponding the second predetermined threshold value accordingly, and described at least one, second degree of correlation of the second operating parameter is not less than its corresponding the second predetermined threshold value.For obtaining of described second degree of correlation, as shown in Figure 2:
