Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The method of the adjustment volume that the embodiment of the present invention provides is implemented in handheld terminal, described handheld terminal comprises smart mobile phone, panel computer, digital audio & video players, electronic reader, handheld game machine and vehicle electronic device etc., described handheld terminal is provided with touch-screen, described touch-screen comprises capacitive sensing screen, resistance induction screen or infrared touch panel etc., can identify multi-point touch operation.
Fig. 1 is a kind of schematic flow sheet regulating the method for volume in the embodiment of the present invention.The flow process of the method for the adjustment volume as shown in the figure in the present embodiment can comprise:
S101, obtains the quantity of the touch point that touch-screen senses.
Described touch point refers to the contact point of touch objects and touch-screen, the finger of such as user and the contact point of touch-screen.It is pointed out that the touch-screen in the embodiment of the present invention supports multi-point touch, thus the quantity of touch point can be multiple.Concrete, when touch screen induction is to when having the external world to input touch control operation, obtain the quantity of the touch point that touch-screen senses.
Optionally, before the quantity obtaining the touch point that touch-screen senses, first determine whether to be in default scene.Described default scene be can be when playing music, when playing video, plugged earphone time or be in the interface of various audiovisual applications program time, etc., do not do exhaustive here.
S102, when the quantity of described touch point is greater than two, obtains the combined motion curve of described touch point.
Concrete, when the quantity of the touch point that touch-screen senses is greater than two, enter volume control mode, and detect the combined motion curve of multiple touch point entirety.Such as, when user uses five fingers to slide on the touchscreen, five corresponding touch points move thereupon, and the track that its mass motion is formed is combined motion curve.
Optionally, in order to avoid maloperation, when the quantity of the touch point that touch-screen senses is three to five, just enter volume control mode.Reason is, the embodiment of the present invention mainly uses finger to carry out the scene of touch control operation for user, and the mode of operation that user is accustomed to most is one-handed performance, and therefore the quantity of touch point generally can not more than five, if more than five touch points, then it is probably user's maloperation unintentionally.
S103, when described combined motion curve is for expansion track or when shrinking track, according to the proportion adjustment volume that it is expanded or shrinks.
As the optional embodiment of one; when combined motion curve is for expansion track or when shrinking track; in the process of touch point motion; determine the minimum circle that can hold all touch points in real time; as shown in Figure 4; and according to the ratio of smallest circle Extendable cycles or contraction, increase accordingly or reduce volume.Such as, suppose that user uses five fingers to slide on the touchscreen, the radius that can hold the minimum circle of five touch points determined in a moment is Ra, the radius that can hold the minimum circle of five touch points determined in the b moment is Rb, then according to ratio and the default algorithm of Rb and Ra, dynamic adjustments volume.In specific implementation process, the current volume value be adjusted to can be asked for according to formula (1), wherein V
