Embodiment
The method of gravity sensor simulated light distance-sensor provided by the invention, when receiving calls, according to gravity sensor, obtaining data judgement mobile phone is in perpendicular screen state or horizontal screen state or perpendicular screen state; Under perpendicular screen state, judge that user adopts handheld mobile phone to be placed on answering mode in one's ear, it is backlight that touch-screen is closed in CPU control, and lock touch-screen to avoid misoperation; Under horizontal screen state, judge that user does not adopt handheld mobile phone to be placed on answering mode in one's ear, do not close touch-screen backlight, do not lock touch-screen to facilitate user's edge joint limit of answering a call to use other functions of mobile phone.
The effect of electrical distance inductor is, by detecting apart from the distance of skin, judge whether user is receiving calls, when judgement user receives calls, close touch-screen backlight, because electrical distance inductor is to judge according to the distance detecting apart from skin whether user is receiving calls, therefore, not in the situation that receiving calls arbitrarily, equal executable operations, such as user is by earphone receiving or while opening hands-free receiving calls, do not close the backlight and locking touch-screen of touch-screen, facilitate user's edge joint limit operating handset of answering a call.Therefore, whether, when the present invention uses gravity sensor simulated light distance-sensor, needing the problem solving is how to judge when user receives calls and adopt handheld mobile phone to be placed on answering mode in one's ear.
Compared to prior art, the method of gravity sensor simulated light distance-sensor provided by the invention, use habit while receiving calls according to most users, when user's handheld mobile phone is placed on while receiving calls in one's ear, in general mobile phone is all perpendicular screen state, when mobile phone being taken while operating in hand, in general mobile phone is horizontal screen state.Therefore, it is in perpendicular screen state or horizontal screen state or perpendicular screen state that the method for gravity sensor simulated light distance-sensor provided by the invention utilizes gravity sensor to obtain data judgement mobile phone, when receiving calls, if perpendicular screen state is closed the backlight and locking touch-screen of touch-screen, to prevent that face from touching touch-screen by mistake; If mobile phone is horizontal screen state, do not close touch-screen backlight and do not lock touch-screen, to facilitate user's edge joint limit operating handset of answering a call.The function of the requisite gravity sensor simulated light of smart mobile phone distance-sensor for the present invention, also can realize its function without electrical distance inductor is set, and can reduce the production cost of mobile phone, dwindles the volume of mobile phone, but also can economize on resources.
Gravity sensor can draw the pressurized dynamics of three directions according to self direction; by two-dimentional gravity sensor; when level is put; the stressed maximum of horizontal direction, the stressed minimum of vertical direction, when vertically putting; the stressed maximum of vertical direction; the stressed minimum of horizontal direction, conventionally can be vertical direction stressed referred to as Y value, horizontal direction stressed referred to as X value.
In the present embodiment, obtain data comprise X value and the Y value that represents mobile phone location state at gravity sensor, CPU judges according to the relation of X value and Y value, and mobile phone is in horizontal screen state or perpendicular screen state.Specifically, y0ffest=5.0, xy0ffest=8.0, when (xy >=xy0ffest) and (Math.abs (y) >=y0ffest) sets up, judge that user is in perpendicular screen state.
The horizontal direction of xy representative and vertical direction angle stressed, no matter where mobile phone is put, the stressed of horizontal direction and vertical direction angle must be greater than this threshold values.What Math.abs (y) > > y0ffest represented is that mobile phone and horizontal direction must keep an angle, like this guarantee now mobile phone at perpendicular screen state, thereby we think that now user is receiving calls.
Above data are according to user's use habit, obtain one group of best threshold values: y0ffest=5.0, xy0ffest=8.0, when (xy >=xy0ffest) and (Math.abs (y) >=y0ffest) sets up, judge that mobile phone is in perpendicular screen state, now can extinguish touch-screen, otherwise touch-screen can be light.
