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, by the terminal that is provided with the light sensing unit Controllable Active light is surveyed, thereby according to the size information of the Controllable Active light that detects with respect to the angle of described light sensing unit, realize contactless volume adjusting.Particularly, the method that the embodiment of the invention at first provides a kind of volume to regulate, the idiographic flow schematic diagram of this method may further comprise the steps as shown in Figure 2:
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, be that cross section is that the parallel Controllable Active light beam of circle is example with Controllable Active light, determine that the Controllable Active light that detects 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, terminal is determined the diameter length value of the circular cross section of this parallel Controllable Active light beam, wherein, the mode of determining this diameter length value has multiple, when the light sensing unit is the light sensing touch-screen, and Controllable Active light is the felt pen corresponding with this terminal when sending, the diameter length value that just can set in advance the circular cross section of the Controllable Active light beam that this felt pen sends is a fixed value, and by with the mode of terminal agreement, this fixed value and this terminal are arranged, thereby make terminal can know the diameter length value, perhaps, terminal also can be determined this diameter length value by the mode that detects, such as, when the light sensing unit detects the cross section of Controllable Active light beam irradiates on the light sensing unit for circle, determine the diameter length that this is circular;
Then, when the cross section of Controllable Active light beam irradiates on the light sensing unit of determining to detect is ellipse, determine oval-shaped long axis length value;
At last, according to long axis length value and the diameter length value determined, determine that the Controllable Active light beam is with respect to the size information of the angle of light sensing unit.Such as, be that cross section is that the parallel Controllable Active light beam of circle is example with Controllable Active light, Controllable Active light beam parallel radiation the light sensing unit and be radiated at obliquely on the light sensing unit schematic diagram 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 diameter of the cross section circle of parallel Controllable Active light beam is a, and be radiated at cross section on the light sensing unit when oval when this parallel Controllable Active light beam oblique illumination makes in the light sensing unit, this oval-shaped long axis length value is to determine the detection of light by the light sensing unit, supposes that the oval-shaped long axis length value of determining is the b shown in Fig. 3.According to Fig. 3 as can be known, according to the method that the embodiment of the invention provides, what need determine 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]:
β＝180°-α [1]
Because angle [alpha] can be regarded an angle in the right-angled triangle shown in Fig. 3 as, and in this right-angled triangle, also exists as shown in the formula the relation shown in [2]:
According to following formula [1], [2], can obtain following formula [3]:
Thereby according to this formula [3], just calculated the value of angle beta.
Certainly, the embodiment of the invention is that cross section is that this fairly simple situation of parallel Controllable Active light beam of circle is example with Controllable Active light only, illustrate how to determine that the Controllable Active light that detects is with respect to the size information of the angle of light sensing unit, those skilled in the art can understand, the cross section of parallel Controllable Active light beam also can not be circular, perhaps the Controllable Active light beam also can not be parallel Controllable Active light beam, and at such Controllable Active light beam, also be to calculate the Controllable Active light that detects with respect to the size information of the angle of light sensing unit by above-mentioned similar method, do not repeat them here.
In addition, in the above-mentioned example, be by to the determining of angle beta size, realize the adjusting to volume, and in fact, also can be directly by to the determining of angle [alpha] size, realize the adjusting to volume.Therefore the implementation procedure comparing class of both of these case seemingly also repeats no more.
