As the enforceable mode of one, in order to improve sensitivity gesture being detected, range sensor can be controlled improve the number of times launching infrared light within the unit interval, launch infrared light with making range sensor high-frequency, the gesture that user makes can be detected quickly.
S201, judges whether the receiving end of described range sensor detects the pulse signal that the signal transmitting terminal of described range sensor sends.
In specific implementation, after the signal transmitting terminal of range sensor launches infrared light, whether the receiving end of judging distance sensor receives the infrared light of reflection, if the receiving end of range sensor detects the infrared light of reflection, then illustrate that the infrared light that the signal transmitting terminal of range sensor is launched is reflected because running into shelter.
S202, when the receiving end of described range sensor detects, the signal transmitting terminal adjusting described range sensor sends pulse signal with second frequency.
In specific implementation, when the receiving end of range sensor detects the infrared light be reflected back, terminal receives the signal of range sensor transmission, and terminal then launches the frequency of infrared light according to the signal transmitting terminal of this signal adjustment range sensor.Concrete, user can not may make identical action when the function by gesture operation control terminal in the short time repeatedly, as user's possibility within the time of 2 seconds can not repeat the action of brandishing to the right, if still launch infrared light to high-frequency the infrared light of reflection therefore detected at the receiving end of range sensor after, then can increase the electric quantity consumption of terminal, increase the pressure that terminal is powered.In order to reduce the electric quantity consumption of terminal, the signal transmitting terminal of terminal Adjustable Range sensor launches the frequency of infrared light, the signal transmitting terminal of range sensor is launched the frequency control of infrared light at second frequency.Wherein, second frequency can be less than first frequency.As shown in Figure 3, when range sensor is after signal transmitting terminal transmitting infrared light 2 seconds, the receiving end of range sensor detected at the 3rd second the infrared light that signal transmitting terminal is launched, then reduce the frequency that signal transmitting terminal launches infrared light, with second frequency launch infrared light, wherein, second frequency can be 1 time per second, then terminal control sensor only launched 1 infrared light in the 3rd second, to reduce the electric quantity consumption of terminal.

S502, when the receiving end of at least one range sensor described detects, the signal transmitting terminal of at least two range sensors described in adjustment sends the frequency of described pulse signal to the 5th frequency.
In specific implementation, when user makes downward gesture relative to the display screen of terminal, the receiving end of the first range sensor and second distance sensor can detect prior to the receiving end of the 3rd range sensor the infrared light that the signal transmitting terminal of self is launched.Because user is when making downward gesture relative to terminal, the receiving end of the first range sensor and the receiving end of second distance sensor detect that the time of the infrared light that respective signal transmitting terminal is launched may be inconsistent, therefore when the receiving end of the first range sensor and the receiving end of second distance sensor detect the infrared light of respective signal transmitting terminal transmitting in Preset Time (mistiming that the receiving end of the first range sensor and the receiving end of second distance sensor receive the infrared light that respective transmitting terminal is launched can ignore), terminal can by the first range sensor, the frequency of the signal transmitting terminal transmitting infrared light of second distance sensor and the 3rd range sensor is all adjusted to the 5th frequency.Wherein, the 5th frequency can be less than the 4th frequency.As shown in Figure 7, when the first range sensor and second distance sensor are after respective signal transmitting terminal transmitting infrared light 2 seconds, the receiving end of the first range sensor and the receiving end of second distance sensor detected the infrared light that respective signal transmitting terminal is launched at the 3rd second, then terminal control first range sensor, second distance sensor and the 3rd range sensor signal transmitting terminal separately reduces the frequency of launching infrared light, infrared light is launched with the 5th frequency, wherein, 5th frequency can be 1 time per second, then terminal control first range sensor, second distance sensor and the 3rd range sensor only launched 1 infrared light in the 3rd second, thus reduce the electric quantity consumption of terminal.
As the enforceable mode of one, the 5th frequency can be zero, and namely the signal transmitting terminal of range sensor stops launching infrared light, thus electric quantity consumption is dropped to minimum.

S504, when the receiving end of at least one range sensor described does not detect, after the time range waiting for setting, the signal transmitting terminal of adjustment at least one range sensor described sends the frequency of described pulse signal to described 6th frequency.
In specific implementation, the frequency that the signal transmitting terminal of at least one range sensor can be launched infrared light by the present embodiment is adjusted to the 6th frequency, and this enforcement is then all adjusted to the 6th frequency with the frequency of above-mentioned three range sensors signal transmitting terminal separately being launched infrared light and is illustrated.
In specific implementation, when the first range sensor, second distance sensor and the 3rd range sensor receiving end separately do not detect the infrared light of respective signal transmitting terminal transmitting, terminal control first range sensor, second distance sensor and the 3rd range sensor signal transmitting terminal separately launch infrared light with the 5th frequency in the time range of setting.Such as, user is after making a gesture to the display screen of terminal, next gesture may be made after 2 seconds, therefore as shown in Figure 7, the time range that terminal can launch infrared light according to the signal transmitting terminal of the behavioural habits setpoint distance sensor of user with the 5th frequency (1 time per second) is 2 seconds.When terminal controlled three range sensors signal transmitting terminal separately with the 5th frequency transmitting infrared light afterwards at the 3rd second, because three range sensors receiving end separately does not all detect the infrared light that respective signal transmitting terminal is launched, therefore terminal controls three range sensors signal transmitting terminal separately with the 5th frequency transmitting infrared light within the time of the 3rd second to the 4th second.After 2 seconds, terminal controls three range sensors signal transmitting terminal separately again and launches infrared light with the 6th frequency, recovers the sensitivity of range sensor.Wherein the 6th frequency is greater than the 5th frequency.
As the enforceable mode of one, the 6th frequency can be equal with the 4th frequency, then, in the figure 7, the 5th second time, the frequency retrieval that respective signal transmitting terminal is launched infrared light by terminal control three range sensors is per second to 4 times.
Adopt the embodiment of the present invention, by starting at least two range sensors, pulse signal is sent with the 4th frequency to make the signal transmitting terminal of at least one range sensor at least two range sensors, judge whether the receiving end of at least one range sensor detects the pulse signal that the signal transmitting terminal of each range sensor sends, when the receiving end of at least one range sensor detects, the signal transmitting terminal of adjustment at least two range sensors sends the frequency of pulse signal, the frequency of the pulse signal that the signal transmitting terminal of adjustment range sensor the sends during pulse signal that the signal transmitting terminal that can receive range sensor at the receiving end of range sensor sends, reduce the consumption of terminal power.
Refer to Fig. 8, Fig. 8 is a kind of terminal structure schematic diagram of the embodiment of the present invention.Terminal as shown in Figure 8 can comprise the first start unit 800, first judging unit 801 and the first adjustment unit 802.
First start unit 800, for starting range sensor, the signal transmitting terminal controlling described range sensor sends pulse signal with first frequency;
First judging unit 801, for judging whether the receiving end of described range sensor detects the pulse signal that the signal transmitting terminal of described range sensor sends;
First adjustment unit 802, for when the judged result of described first judging unit 801 is for being, the signal transmitting terminal adjusting described range sensor sends pulse signal with second frequency.
In specific implementation, the present embodiment is still for single range sensor transponder pulse signal, and terminal, after the direction of motion of start detection gesture, starts range sensor, makes the signal transmitting terminal of range sensor launch infrared light with first frequency.Launch after infrared light with first frequency at the signal transmitting terminal of range sensor, the infrared light that the receiving end wait-receiving mode of range sensor is reflected back.Wherein, the signal transmitting terminal of range sensor launches the frequency of infrared light is launch the number of times of infrared light in the unit time.As shown in Figure 3, Fig. 3 is the sequential chart of range sensor transponder pulse signal, for the pulse signal launched for infrared light, first stage is that terminal startup range sensor launches infrared light with first frequency, suppose that its unit interval is 1 second, if range sensor sequential filming 4 times within the unit interval of first stage, then first frequency be 4 times per second.
As the enforceable mode of one, in order to improve sensitivity gesture being detected, range sensor can be controlled improve the number of times launching infrared light within the unit interval, launch infrared light with making range sensor high-frequency, the gesture that user makes can be detected quickly.
In specific implementation, after the signal transmitting terminal of range sensor launches infrared light, whether the receiving end of judging distance sensor receives the infrared light of reflection, if the receiving end of range sensor detects the infrared light of reflection, then illustrate that the infrared light that the signal transmitting terminal of range sensor is launched is reflected because running into shelter.
In specific implementation, when the receiving end of range sensor detects the infrared light be reflected back, terminal receives the signal of range sensor transmission, and terminal then launches the frequency of infrared light according to the signal transmitting terminal of this signal adjustment range sensor.Concrete, user can not may make identical action when the function by gesture operation control terminal in the short time repeatedly, as user's possibility within the time of 2 seconds can not repeat the action of brandishing to the right, if still launch infrared light to high-frequency the infrared light of reflection therefore detected at the receiving end of range sensor after, then can increase the electric quantity consumption of terminal, increase the pressure that terminal is powered.In order to reduce the electric quantity consumption of terminal, terminal can reduce the frequency of the signal transmitting terminal transmitting infrared light of range sensor, the signal transmitting terminal of range sensor is launched the frequency control of infrared light at second frequency.Wherein, second frequency can be less than first frequency.As shown in Figure 3, when range sensor is after signal transmitting terminal transmitting infrared light 2 seconds, the receiving end of range sensor detected at the 3rd second the infrared light that signal transmitting terminal is launched, then reduce the frequency that signal transmitting terminal launches infrared light, with second frequency launch infrared light, wherein, second frequency can be 1 time per second, then terminal control sensor only launched 1 infrared light in the 3rd second, to reduce the electric quantity consumption of terminal.
As the enforceable mode of one, second frequency can be zero, and namely the signal transmitting terminal of range sensor stops launching infrared light, thus electric quantity consumption is dropped to minimum.
As the enforceable mode of one, described first judging unit 801, also for judging whether the receiving end of described range sensor detects the pulse signal that the signal transmitting terminal of described range sensor sends with described second frequency;

In specific implementation, in order to the direction of motion of user's gesture can be detected more accurately, in terminal, at least two range sensors can be set, and the signal transmitting terminal controlling wherein at least one range sensor launches infrared light with the 4th frequency.This enforcement is to arrange three sensors in terminal, as shown in Figure 6, wherein terminal built-in has the first range sensor, second distance sensor and the 3rd range sensor, wherein, first range sensor, second distance sensor and the 3rd range sensor are distributed in three sides in terminal display screen, the first range sensor, second distance sensor and the 3rd range sensor are distributed in upper and lower, the left and right direction of motion of three side identifiable design gestures in terminal display screen.The signal transmitting terminal that terminal can control the first range sensor, second distance sensor and the 3rd range sensor all launches infrared light with the 4th frequency.
In specific implementation, as shown in Figure 6, when user makes downward gesture relative to the display screen of terminal, whether the receiving end of at least one range sensor that terminal can judge in the first range sensor, second distance sensor and the 3rd range sensor detects the infrared light that respective signal transmitting terminal is launched with the 4th frequency respectively.
In specific implementation, if the receiving end of wherein any one range sensor of the first range sensor and second distance sensor detects the infrared light that the signal transmitting terminal of self is launched, the frequency of the infrared light of the signal transmitting terminal transmitting of terminal adjustable first range sensor and second distance sensor.Concrete, user can not make identical action when the function by gesture operation control terminal in the short time repeatedly, as user can not repeat the action of brandishing to the right within the time of 2 seconds, if still launch infrared light to high-frequency the infrared light of reflection therefore detected at the receiving end of range sensor after, the electric quantity consumption of terminal can be increased, and increase the pressure that terminal powers.In order to reduce the electric quantity consumption of terminal, the frequency of the transmitting infrared light after adjustment can be less than the 4th frequency, to reduce the energy ezpenditure of battery.
As the enforceable mode of one, the frequency of the transmitting infrared light after adjustment can be zero, and namely the signal transmitting terminal of range sensor stops launching infrared light.
As the enforceable mode of one, described 3rd adjustment unit 1002, also for when the judged result of described second judging unit 1001 is for being, the signal transmitting terminal of at least two range sensors described in adjustment sends the frequency of described pulse signal to the 5th frequency.
In specific implementation, when user makes downward gesture relative to the display screen of terminal, the receiving end of the first range sensor and second distance sensor can detect prior to the receiving end of the 3rd range sensor the infrared light that the signal transmitting terminal of self is launched.Because the user receiving end of the first range sensor and receiving end of second distance sensor when making downward gesture relative to terminal detect that the time of the infrared light that respective signal transmitting terminal is launched may be inconsistent, therefore when the receiving end of the first range sensor and the receiving end of second distance sensor detect the infrared light of respective signal transmitting terminal transmitting in Preset Time (mistiming that the receiving end of the first range sensor and the receiving end of second distance sensor receive the infrared light that respective transmitting terminal is launched can ignore), terminal can by the first range sensor, the frequency of the signal transmitting terminal transmitting infrared light of second distance sensor and the 3rd range sensor is adjusted to the 5th frequency.Wherein, the 5th frequency can be less than the 4th frequency.As shown in Figure 7, when the first range sensor and second distance sensor are after respective signal transmitting terminal transmitting infrared light 2 seconds, the receiving end of the first range sensor and the receiving end of second distance sensor detected the infrared light that respective signal transmitting terminal is launched at the 3rd second, then terminal control first range sensor, second distance sensor and the 3rd range sensor signal transmitting terminal separately reduces the frequency of launching infrared light, infrared light is launched with the 5th frequency, wherein, 5th frequency can be 1 time per second, then terminal control first range sensor, second distance sensor and the 3rd range sensor only launched 1 infrared light in the 3rd second, thus reduce the electric quantity consumption of terminal.
As the enforceable mode of one, the 5th frequency can be zero, and namely the signal transmitting terminal of range sensor stops launching infrared light, thus electric quantity consumption is dropped to minimum.
As the enforceable mode of one, described second judging unit 1001, also for judging whether the receiving end of at least one range sensor described detects the pulse signal that the signal transmitting terminal of each range sensor sends with described 5th frequency;
