In the embodiment of the application, the sensing information may be sensing values of a plurality of sensing units which are changed according to the input light spot in a sensing array of the display screen, wherein the sensing values are obtained by the electronic device after the input light spot is taken in the display screen of the electronic device. It should be noted that the sensing information may be that after an input light spot is projected onto a display screen in a real environment, a sensing unit in the sensing array senses the input light spot to determine a sensing value, or the sensing information may be that a real light environment is simulated by application software to project the input light spot onto the display screen in the simulated scene, so that the sensing unit in the sensing array of the simulated scene senses the input light spot to determine the sensing value. In one possible implementation, the input light spot may be generated after the infrared light is projected onto the display screen.
The second sensing unit region may be adjacent to one of the upper, lower, left and right sides of the first sensing unit region, or may be a plurality of sensing unit regions adjacent to a plurality of the upper, lower, left and right sides of the first sensing unit region, or may be a plurality of sensing unit regions adjacent to each of the upper, lower, left and right sides of the first sensing unit region, i.e., the second sensing unit region surrounds the first sensing unit region.
Step 102, determining the input position of the input light spot on the display screen based on the sensing information.
In the embodiment of the application, the electronic equipment can analyze the sensing information of the sensing unit areas to determine the sizes of the corresponding sensing unit areas, and then can determine the input positions of the input light spots on the display screen according to the sizes of the sensing unit areas.
And 103, controlling to display an input focus corresponding to the input light spot on a display screen based on the input position.
After determining the input position of the input light spot on the display screen, the electronic device may display an input focus corresponding to the input light spot at the input position on the display screen, where it is to be noted that the input focus may be used to indicate which information in the electronic device is processed.
According to the processing method provided by the embodiment of the application, the input light spots input on the display screen are sensed through the plurality of sensing units comprising the second sensing unit area and the first sensing unit area corresponding to the input light spots one by one, the input focus of the input light spots on the display screen is determined according to the sensing information of the plurality of sensing units, and the condition that the sensing units are larger than the light spots is avoided, so that the problem that the position of the light spots on the display screen is inaccurate to the position alignment actually triggered in the scheme of triggering the electronic equipment through infrared light in the related art is solved.
Based on the foregoing embodiments, an embodiment of the present application provides a processing method, referring to fig. 2, including the steps of:
Step 201, the electronic device obtains sensing information of the input light spot projected onto the sensing array through the optical scattering layer of the display screen to form a scattering light spot.
The sensing area on the sensing array corresponding to the scattering light spot comprises a first sensing unit area and a second sensing unit area.
It should be noted that, referring to fig. 3, the input light spot may be generated after the infrared light is projected onto the display screen by a transmitting device capable of emitting infrared light, and in a possible implementation, the transmitting device may be a transmitting pen or a remote controller.
In the embodiment of the application, the optical scattering layer can enlarge the size of the input light spot projected onto the display screen and form the scattering light spot based on the input light spot, so that more sensing units in the sensing array sense the input light spot, and the light sensing device is not required to be small enough, thereby ensuring the precision of the finally determined input position. Referring to fig. 4, the size of an input spot is increased after a beam of infrared light input to the display screen is scattered by the optical scattering layer, forming a larger area of infrared light spot.
Step 202, the electronic device obtains first sensing information.
The first sensing information is obtained by projecting an input light spot to the sensing array.
In the embodiment of the present application, the first sensing information may be a sensing value of a sensing unit that changes after an input light spot generated after the infrared light is emitted to the display screen by the emitting device capable of emitting infrared light is projected to the sensing array.
Step 203, the electronic device determines the expansion area based on the first sensing information, and generates second sensing information of the expansion area.
In the embodiment of the application, after the first sensing unit area is obtained, the area after the diffusion of the input light spots can be simulated by application software to serve as an expansion area, and further the second sensing information is the sensing value of the sensing unit at the expansion area determined based on the first sensing information, wherein in practical application, the distance between the display screen and the sensing unit can be determined based on the first sensing unit, and the expansion area can be determined based on the angle of light scattering and the distance between the display screen and the sensing unit. The expansion area is, for example, rectangular or circular, elliptical, or the like, and, in the case of the multivalued sensing unit, the closer to the second sensing unit at the position of the sensing unit corresponding to the input light spot, the larger the value of the corresponding second sensing information thereof is determined by simulation.
For the case of the binary sensing unit, the sensing value at the extended area is binary (0 and 1), if the sensing value is 1, the extended area senses light, and if the sensing value is 0, the extended area does not sense light, and at this time, the second sensing information can be determined by the sensing unit corresponding to the extended area.
In step 204, the electronic device uses the first sensing information and the second sensing information as sensing information.
The first sensing information and the second sensing information can be used together as finally obtained sensing information, so that the input position of the input light spot on the display screen can be determined based on the sensing information.
It should be noted that steps 205-207 may be performed after step 201 or steps 202-204.
Step 205, the electronic device determines a center point of the sensing area characterized by the sensing information.
The electronic device may analyze the sensing information to determine the sizes of the first sensing unit area and the second sensing unit area, and then determine the center point of the whole area, where it is to be noted that the sizes of the first sensing unit area and the second sensing unit area in the embodiment of the present application are not the sizes of the first sensing unit area and the second sensing unit area in physical, but the sizes determined based on the sizes of the sensing information.
In an embodiment of the present application, step 205 may be implemented by:
in step 205a, the electronic device determines a sensing area size corresponding to each sensing unit based on the sensing values and the upper threshold value in the sensing units.
Wherein the sensed value is a plurality of values, the plurality of values being related to the amount of light sensed, the plurality of values having an upper threshold.
In the embodiment of the application, the size of the sensing area corresponding to the sensing unit can be determined based on the magnitude of the light quantity sensed by the sensing unit and the upper threshold corresponding to the sensing value, in one possible implementation, the upper threshold of the sensing value is 128, and the range of a plurality of values included in the sensing value is 0-128, so that the size of the sensing area corresponding to the sensing unit corresponding to different sensing values can be determined based on the preset corresponding relation between the sensing value and the sensing area size, and the size of the sensing area corresponding to each sensing unit is determined.
In other embodiments of the present application, the sensing value may be expressed in a binary form, that is, the sensing value may include two values, namely, 0 and 1, if the sensing value is a first value of 1, it indicates that the sensing unit senses light, and if the sensing value is a second value of 0, it indicates that the sensing unit does not sense light, and at this time, the size of the sensing area may be determined based on the size of the sensing unit whose sensing value is the first value.
Step 205b, the electronic device determines the center of the sensing area based on the sensing area sizes of the plurality of sensing units.
The sensing area sizes of the sensing units may be analyzed to determine a center point of the sensing area.
In an embodiment of the present application, step 205b may be implemented by:
and determining the sensing unit with the largest sensing value among the sensing units as the sensing unit with the reference center of the sensing area, and determining the center of the sensing area based on the size of the sensing area of the sensing units and the reference center.
When determining the center of the sensing area, the sensing unit with the largest sensing value can be determined from the sensing units as the sensing unit corresponding to the reference center, that is, the reference center is in the sensing unit with the largest sensing value, and then the center of the sensing area can be determined from the sensing units based on the sensing area size of each sensing unit and the reference center. That is, the center position to be selected may be determined based on the sensing region size, and the center of the sensing region may be determined as the center of the sensing region from among the center positions to be selected.
Step 206, the electronic device uses the center point as the input position of the input light spot.
The input position and the position of the input light spot on the display screen overlap, that is, the position of the input light spot on the display screen is the position corresponding to the center point on the display screen, and the input position on the display screen is the position corresponding to the center point on the display screen.
Or alternatively;
The first difference between the input position and the position of the input light spot on the display screen is smaller than the second difference between the sensing position of the input light spot on the first sensing unit area and the position of the input light spot on the display screen, namely, the first difference is smaller than the second difference, so that the input position is closer to the position of the input light spot.
Step 207, the electronic device controls to display an input focus corresponding to the input light spot on the display screen based on the input position.
In other embodiments of the present application, when the transmitting device transmits infrared light not perpendicular to the display screen, the electronic device determines, based on the gravity sensor, a receiving angle at which the display screen receives the input light spot, and then may determine, based on a distance between the display screen and a layer where the sensing array is located and the receiving angle, an offset of the input light spot on the layer where the sensing array is located, and correct the input position based on the offset.
According to the processing method provided by the embodiment of the application, the input light spots input on the display screen are sensed through the plurality of sensing units comprising the second sensing unit area and the first sensing unit area corresponding to the input light spots one by one, the input focus of the input light spots on the display screen is determined according to the sensing information of the plurality of sensing units, and the condition that the sensing units are larger than the light spots is avoided, so that the problem that the position of the light spots on the display screen is inaccurate to the position alignment actually triggered in the scheme of triggering the electronic equipment through infrared light in the related art is solved.
