Embodiment

For making object of the present invention, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, the present invention is described in more detail.

Refer to Fig. 1, in embodiments of the present invention, remote controller 10 can launch infrared signal to the optional position in the indication range of display screen 20, instead of only fixing to a position infrared remote receiver sends infrared signal as prior art, correspondingly, display screen 20 can any position in its indication range sense remote controller 10 launch infrared signal, and, can according to the signal of telecommunication be converted to by infrared signal and straighforward operation corresponding to the infrared projection location triggered of infrared signal in the indication range of display screen 20 with the processor 30 that display screen 20 is electrically connected.

Based on this, utilize the infrared projection change in location of infrared signal in the indication range of display screen 20, the embodiment of the present invention can realize in the indication range of display screen 20 can the switching of operand, further, such infrared projection change in location directly can also be converted to corresponding straighforward operation, thus, infrared projection position not only can be utilized to substitute traditional focus, and depart from focus thus to the restriction of remote control, and, except operating based on the single-point of single infrared projection position, the gesture operation of the motion track formed based on infrared projection position can also be realized alternatively.

In order to realize above-mentioned infrared remote control principle, in embodiments of the present invention, except the infrared transmitter comprised for launching infrared signal except needing remote controller, infrared signal infrared transmitter can launched also is equipped with to be polymerized to by dispersion shape the condenser that linear infrared signal launches light path, and, in the present embodiment, also need to improve the traditional structure of display screen 20 and the conventional arrangement of processor 30, be described in detail respectively below.

Refer to Fig. 2, the display screen 20 that the embodiment of the present invention is improved in order to the infrared remote control principle realized as shown in Figure 1 comprises:

Limit the display floater 21 of the indication range of display screen 20;

And, be distributed in infrared sensor 22 array of display floater 21, wherein, each infrared sensor 22 in infrared sensor 22 array is for sensing the infrared signal of the corresponding position being incident upon display floater 21 and exporting being converted to the signal of telecommunication with this infrared sensor 22 in the infrared signal that the corresponding distributing position of display floater 21 is infrared projection position.

Wherein, can also indirectly or directly provide the infrared signal being converted to this signal of telecommunication in the infrared projection position of display floater 21 while can exporting the signal of telecommunication:

When any one infrared sensor 22 produces the signal of telecommunication, the arrangement position of this infrared sensor 22 in infrared sensor 22 array can be used for identifying that this infrared sensor 22 is at the distributing position of display floater 21 correspondence and by the distributing position identified to determine the infrared projection position of the infrared signal that this infrared sensor 22 senses, that is, infrared projection position is indirectly provided;

Or, when any one infrared sensor 22 produces the signal of telecommunication, its distributing position in display floater 21 correspondence can be packaged in the signal of telecommunication (such as can the form of signal heads be packaged in the signal of telecommunication) by this infrared sensor 22 as infrared projection position, namely, infrared projection position is directly provided, now, the programmable sensor with programmable functions selected by infrared sensor 22 needs.

In addition, in actual applications, infrared sensor 22 array can according to actual needs at display floater 21 with the even laying of arbitrary distribution density, correspondingly, an infrared sensor 22 can be the single locus with a pixel aligned in position at the corresponding distributing position of display floater 21, also can for covering the regional location of any amount pixel position.

And, although the infrared signal of scattering is converged light microscopic and is collected for linear infrared emission light path, but due to the scattering properties of infrared signal itself, along with remote controller 10 is different apart from the distance of display screen 20, infrared signal still can be correspondingly different in the size of the infrared projection point that the display floater 21 of display screen 20 is formed, thus, an infrared projection point position can be formed and only cover the area coverage of an infrared sensor 22 at the distributing position of display floater 21, namely an infrared sensor 22 is now only had uniquely to sense infrared signal, or, an infrared sensor 22 also can be formed and cover the area coverage of multiple infrared sensor 22 at the distributing position of display floater 21 simultaneously, namely now there is multiple infrared sensor 22 to sense same infrared signal simultaneously.

Refer to Fig. 3, the embodiment of the present invention is in order to realize infrared remote control principle as shown in Figure 1, and can carry a kind of remote control unit by configuration processor 30, this remote control unit comprises:

Receive acquisition module 31, the signal of telecommunication be converted to by infrared signal that acquisition display screen 20 exports and this infrared signal are in the infrared projection position of the display floater 21 of display screen 20;

Receiving processing module 32, carries out precision process to the infrared projection position got;

Directive generation module 33, according to the signal of telecommunication got and infrared projection position, identifies the corresponding operational order represented by infrared signal;

Operation executing module 34, triggers corresponding operation according to the operational order identified.

For reception acquisition module 31:

When display screen 20 provides infrared projection position indirectly, receiving acquisition module 31 can according to the distributing position of each infrared sensor 22 this infrared sensor 22 of arrangement position identification in infrared sensor 22 array in display floater 21 correspondence, and (an infrared projection point position is formed and only covers the area coverage of an infrared sensor 22 at the distributing position of display floater 21 to be defined as infrared projection position according to the distributing position identifying one or more infrared sensor 22, cover the two kind situations of multiple infrared sensor 22 in the area coverage of the distributing position of display floater 21) simultaneously,

When display screen 20 directly provides infrared projection position, receive the distributing position of this infrared sensor 22 in display floater 21 correspondence that acquisition module 31 can identify encapsulation from the signal of telecommunication of each infrared sensor 22 generation, and (an infrared projection point position is formed and only covers the area coverage of an infrared sensor 22 at the distributing position of display floater 21 to be defined as infrared projection position according to the distributing position identifying one or more infrared sensor 22, cover the two kind situations of multiple infrared sensor 22 in the area coverage of the distributing position of display floater 21) simultaneously.

For receiving processing module 32:

Due to infrared projection position area coverage along with remote controller 10 to vary in size apart from the distance of display floater 21 and can cause when the area coverage of infrared launching position is excessive being difficult to accurately navigating to single-point operation institute for can operand or be difficult to determine whether formation movement locus and the shape and the movement tendency that are difficult to accurately identify movement locus, therefore, the precision process performed by receiving processing module 32 can be by normalized for the size of the area coverage of infrared projection position process.

Specifically, refer to Fig. 4 a, receiving processing module 32 can specifically comprise:

Accuracy test submodule 32a, judges whether the area coverage of infrared projection position exceeds the predetermined upper limit;

Precision improvement submodule 32b, if the area coverage of infrared projection position exceeds the aforementioned upper limit, is then reduced to the area coverage of infrared projection position and is less than or equal to the aforementioned upper limit.

In practical application, infrared projection position is typically expressed as circular pattern information, correspondingly, according to the diameter of circular pattern information, accuracy test submodule 32a can judge whether the area coverage of infrared projection position exceeds the aforementioned upper limit, precision improvement submodule 32b can replace the mode that diameter exceedes the circular pattern information of the aforementioned upper limit by the concentric circles being less than or equal to the aforementioned upper limit with diameter, the area coverage exceeding the aforementioned upper limit of infrared projection position be reduced to and be less than or equal to the aforementioned upper limit.

Or refer to Fig. 4 b, receiving processing module 32 also can specifically comprise:

Coordinate extracts submodule 32a ', extracts the centre coordinate in the area coverage obtaining the formation of infrared projection position;

Precision normalizing submodule 32b ', the centre coordinate in the area coverage formed with each infrared projection position represents this infrared projection position.

In practical application, be the situation of circular pattern information for infrared projection positional representation, above-mentioned centre coordinate can be the central coordinate of circle of circular pattern information.

But it should be noted that, receiving processing module 32 is optionally nonessential, as long as there is certain tolerance to the precision of infrared projection position, can not arrange receiving processing module 32.

For directive generation module 33:

When an infrared projection position of any time is isolated to other infrared projection positions of adjacent moment, directive generation module 33 can generate corresponding operational order according to the signal of telecommunication of this infrared projection position and correspondence thereof, now just belong to single-point operation, the operational order generated according to the signal of telecommunication of an infrared projection position and correspondence thereof only in display floater 21 with this infrared projection location overlap can operand (such as with the menu option of this infrared projection location overlap, with the option icons etc. of this infrared projection location overlap), correspondingly, the instruction type that the infrared signal forming isolated infrared projection position comprises is (such as by frequency, duration, or the combination of frequency and duration) can be the same or different (such as all represents or represent click respectively, length is pressed), and, the instruction type that the signal of telecommunication be converted to respectively by the infrared signal forming isolated infrared projection position comprises is (such as by the frequency of infrared signal, duration, or frequency and the level combinations that the Combination conversion of duration obtains) also can be identical or different,

When in continuous print multiple infrared projection position forming position in time during continuous print movement locus, directive generation module 33 can generate corresponding operational order according to movement locus (shape of such as movement locus and/or movement tendency), now just belong to the situation of gesture operation, according to trace generator operational order can in display floater 21 optional position display can operand (in such as display floater 21 certain optional position display expression broadcast soon, playback, return, or the button icon of page turning, or the icon set etc. that in display floater 21, multiple position shows respectively), correspondingly, forming the instruction type comprised in the infrared signal of these continuous print infrared projection positions, position can be identically (such as all represent slip usually, frame choosing etc.), and, the instruction type that the signal of telecommunication be converted to by the infrared signal forming these continuous print infrared projection positions, position comprises also is identical.

Specifically, see Fig. 5, directive generation module 33 can specifically comprise:

Track detection submodule 33a, whether the infrared projection position detecting each moment can form movement locus with the infrared projection position in continuous multiple moment before this;

Single-point operator module 33b, if the infrared projection position of any instant does not form movement locus with the infrared projection position of previous moment, then according to the signal of telecommunication generating run instruction that the infrared projection position in this moment is corresponding with it;

Single-point cache sub-module 33c, stores and does not form the described infrared projection position of movement locus and the moment of correspondence thereof and the signal of telecommunication, uses when detecting the infrared projection position of following instant for track detection submodule 33a;

Track operator module 33d, if the infrared projection position in the infrared projection position of any instant and before this multiple moment forms movement locus, then according to trace generator operational order.

In actual applications, the module included by above-mentioned remote control unit being carried on processor 30 can for the software module based on computer program, correspondingly, also can be understood as, processor 30 performs a kind of method for remotely controlling realized by computer program.

Refer to Fig. 6, this method for remotely controlling comprises:

Step 601, the signal of telecommunication be converted to by infrared signal that acquisition display screen exports and infrared signal are in the infrared projection position of the display floater of display screen.

Step 602, carries out precision process to the infrared projection position got;

Step 603, according to the signal of telecommunication got and infrared projection position, identifies the corresponding operational order represented by infrared signal;

Step 604, triggers corresponding operation according to the operational order identified.

So far, a remote control flow process terminates.

Step 601 in above-mentioned flow process is corresponding with the reception acquisition module 31 in previously described remote control unit.

Therefore, when display screen 20 provides infrared projection position respectively indirectly and directly, the concrete obtain manner of step 601 pair infrared projection position is identical with reception acquisition module 31, repeats no more herein.

Step 602 in above-mentioned flow process is corresponding with the receiving processing module 32 in previously described remote control unit.

Therefore, the specific implementation of step 602 specifically can comprise see Fig. 7 a:

Step 602a, after step 601, judges whether the area coverage of infrared projection position exceeds the predetermined upper limit;

Step 602b, if the area coverage of infrared projection position exceeds the aforementioned upper limit, is then reduced to the aforementioned upper limit by the area coverage of infrared projection position, and then performs step 603 for this infrared projection position;

And, if the area coverage of infrared projection position does not exceed the aforementioned upper limit, then after step 602a, directly perform step 603 for this infrared projection position.

So far, a precision flow process terminates.

Correspondingly, with receiving processing module 32 in like manner:

When infrared launching position is typically expressed as circular pattern information, according to the diameter of circular pattern information, step 602a can judge whether the area coverage of infrared projection position exceeds the aforementioned upper limit, step 602b can replace the mode that diameter exceedes the circular pattern information of the aforementioned upper limit by the concentric circles equaling the aforementioned upper limit with diameter, the area coverage exceeding the aforementioned upper limit of infrared projection position is reduced to the aforementioned upper limit.

Or the specific implementation of step 602 also specifically can comprise see Fig. 7 b:

Step 602a ', after step 601, extracts the centre coordinate in the area coverage obtaining the formation of infrared projection position;

Step 602b ', the centre coordinate in the area coverage formed with each infrared projection position represents this infrared projection position, and then performs step 603 for this infrared projection position.

So far, a precision flow process terminates.

Correspondingly, be the situation of circular pattern information for infrared projection positional representation, above-mentioned centre coordinate can be the central coordinate of circle of circular pattern information.

In addition, step 602 is optional and nonessential, as long as there is certain tolerance to the precision of infrared projection position, and can not setting steps 602 but directly jump to step 603 by step 601.

Step 603 in above-mentioned flow process is corresponding with the directive generation module 33 in previously described remote control unit, therefore, when an infrared projection position of any time is isolated to other infrared projection positions of adjacent moment, step 603 can generate corresponding operational order according to the signal of telecommunication of this infrared projection position and correspondence thereof, to realize single-point operation, when in continuous print multiple infrared projection position forming position in time during continuous print movement locus, step 603 can generate corresponding operational order according to movement locus (shape of such as movement locus and/or movement tendency), to realize gesture operation.Correspondingly, see Fig. 8, step 603 can specifically comprise:

Step 603a, whether the infrared projection position detecting each moment can form movement locus with the infrared projection position in continuous multiple moment before this;

Step 603b, if the infrared projection position of any instant does not form movement locus with the infrared projection position of previous moment, then according to the signal of telecommunication generating run instruction that the infrared projection position in this moment is corresponding with it;

Step 603c, stores and does not form the infrared projection position of movement locus and the moment of correspondence thereof and the signal of telecommunication, uses when detecting the infrared projection position of following instant for step 603a;

Step 603d, if the infrared projection position in the infrared projection position of any instant and before this multiple moment forms movement locus, then according to trace generator operational order;

Thus, the above-mentioned flow process performed by one or many circulation can obtain operational order.
