Embodiment
In order to solve the behavioural information that under relatively poor environment, is difficult to accurately catch the user that contactless regulative mode that prior art provides exists; Thereby can't make the defective that accurate volume is regulated; The scheme that the embodiment of the invention provides a kind of volume to regulate; Terminal through being provided with the light sensing unit is surveyed Controllable Active light, thereby according to the size information of the Controllable Active light that detects with respect to the angle of said light sensing unit, realizes contactless volume adjusting.Particularly, the method that the embodiment of the invention at first provides a kind of volume to regulate, the idiographic flow sketch map of this method is as shown in Figure 2, may further comprise the steps:
In embodiments of the present invention; Controllable Active light can be circular taper Controllable Active light beam for the cross section that sends from light source; Also can be parallel Controllable Active light beam; With Controllable Active light is that cross section is that the parallel Controllable Active light beam of circle is an example, and the Controllable Active light of confirming to detect specifically can may further comprise the steps with respect to the process of the size information of the angle of light sensing unit:
At first, the diameter length value of the circular cross section of this parallel Controllable Active light beam is confirmed at the terminal, wherein; The mode of confirming this diameter length value has multiple, and when the light sensing unit is the light sensing touch-screen, and Controllable Active light is when sending for the felt pen corresponding with this terminal; The diameter length value of the circular cross section of the Controllable Active light beam that just can in advance this felt pen be set and be sent is a fixed value, and through with the mode of terminal agreement, this fixed value and this terminal are arranged; Thereby make the terminal can know the diameter length value; Perhaps, this diameter length value also can be confirmed through the mode that detects in the terminal, such as; When the light sensing unit detects the cross section of Controllable Active light beam irradiates on the light sensing unit for circle, confirm the diameter length that this is circular;
Then, when the cross section of Controllable Active light beam irradiates on the light sensing unit of confirming to detect is ellipse, confirm oval-shaped long axis length value;
At last, according to long axis length value and the diameter length value confirmed, confirm the size information of Controllable Active light beam with respect to the angle of light sensing unit.Such as, be that cross section is that the parallel Controllable Active light beam of circle is an example with Controllable Active light, the Controllable Active parallel beam be radiated at the light sensing unit and the sketch map that is radiated at obliquely on the light sensing unit as shown in Figure 3.In this Fig. 3; The parallel Controllable Active light beam of vertical irradiation is represented with straight line; And the parallel Controllable Active light beam of oblique illumination dots; Wherein, the circular diameter of the cross section of parallel Controllable Active light beam is a, and makes in the light sensing unit when being radiated at cross section on the light sensing unit for ellipse when this parallel Controllable Active light beam oblique illumination; This oval-shaped long axis length value is to determine the detection of light through the light sensing unit, supposes that the oval-shaped long axis length value of determining is the b shown in Fig. 3.Can know that according to Fig. 3 according to the method that the embodiment of the invention provides, what need confirm is the value of angle beta, and exists between angle beta and the angle [alpha] as shown in the formula the relation shown in [1]:
