Also, the second electronic device 200 includes a second projection unit 201 (not shown), and projects a second projection area 202 on the projection surface through the second projection unit 201, and projects second projection content in the second electronic device 200 into the second projection area through the second in-projection unit 201. In the system shown in fig. 1, the first electronic device 100, as a master device for controlling the first projection content and the second projection content, may execute the data processing method provided in the embodiment of the present invention to process the first projection content and the second projection content.

Of course, in actual operation, the second electronic device 200 may also serve as a master device for controlling the first projection content and the second projection content, and it may also execute the data processing method provided by the embodiment of the present invention. In the embodiment of the present invention, the data processing method provided in the embodiment of the present invention will be described with the first electronic device 100 as an execution subject.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 2, a data processing method applied to a first electronic device according to an embodiment of the present invention is shown, which includes the following steps:

201: and acquiring the position relation of the first projection area and the second projection area.

Wherein the positional relationship is a positional relationship formed by the first projection region and the second projection region on the projection plane, and the positional relationship includes: the second projection area is located in the first projection area (all overlap), the second projection area and the first projection area are partially overlapped, the second projection area is not located in the first projection area, one side of the second projection area is overlapped with one side of the first projection area, and the first projection area and the second projection area are separated (the two projection areas are not overlapped).

In some examples of the embodiment of the present invention, the first electronic device further includes a first acquisition unit, a projection image formed by the first projection area and the second projection area on the projection surface is acquired by the first acquisition unit, and the first electronic device may obtain a positional relationship between the first projection area and the second projection area by analyzing the projection image. However, the acquisition field of view of the first acquisition unit is limited, and when the first electronic device is located at a smaller distance from the projection surface, the larger the first projection area formed on the projection surface, the first acquisition unit may acquire only a partial area of the first projection area, so that the first electronic device cannot know the position relationship between the first projection area and the second projection area from the projection image.

In other examples of the embodiments of the present invention, the first electronic device may determine the position relationship of the first projection area and the second projection area by determining whether a distance between center points of the first projection area and the second projection area is less than half of a sum of lengths of the first projection area and the second projection area.

For example, if the distance between the center points of the first projection unit and the second projection unit is d, the length of the first projection area is a, and the length of the second projection area is b, if d is less than (a + b)/2, the first electronic device may determine that the first projection area and the second projection area overlap; if d is equal to (a + b)/2, the first electronic device may determine that the second projection region is not in the first projection region and one edge of the second projection region overlaps one edge of the first projection region; if d is greater than (a + b)/2, the first electronic device may determine that the first projection region and the second projection region are separated; if d is judged to be less than a/2 and d is greater than b/2 on the basis that d is less than (a + b)/2, the first electronic device may determine that the second projection region is located in the first projection region.

The central points of the first projection area and the second projection area are points formed on the projection surface by the light rays passing through the axis in the light rays projected by the respective projection units, the light rays passing through the axis are the light rays emitted by the central points of the projection units, and the light ray lines of the light rays do not change when the light rays pass through the axis. The distance between the two central points is related to the distance (called the axle distance for short) between the axle centers of the first projection unit and the second projection unit, and when the first projection unit and the second projection unit vertically project, the distance between the two central points is equal to the axle distance; when the axes of the first projection unit and the second projection unit rotate up and down along the horizontal axis, the distance between the two central points is equal to the distance between the axes; when the axes of the first projection unit and the second projection unit rotate left and right along the vertical axis, the distance between the two central points is related to the distance between the axes, the rotation direction and the rotation angle.

If the distance between the center points of the first projection unit and the second projection unit is d, the first projection unit rotates right along the vertical axis, and the second projection unit rotates left along the vertical axis, the distance between the center points is m-p cosa-q cosb, where m is the axial distance, p is the depth information (i.e., the distance to the projection plane) of the first projection unit, a is the rotation angle of the first projection unit, q is the depth information of the second projection unit, and b is the rotation angle of the second projection unit. If the first projection unit is rotated to the left and the second projection unit is rotated to the right, the distance d from the center point is m + p cosa + q cosb.

The length of the first projection area and the length of the second projection area can be determined by projection parameters of the respective projection units, and the first electronic device can acquire various parameters of the second projection area from the second electronic device through the data transmission channel, wherein the various parameters include the length of the second projection area.

202: and acquiring second projection content from the second electronic equipment through the data transmission channel. The second projection content is a content projected on the projection surface by the second projection unit, and may be a segment of text, data, or an image, and is specifically determined by a user of the second electronic device according to an application scenario.

203: and analyzing the first projection content and the second projection content based on the position relation to obtain a first analysis result, wherein the first analysis result is used for representing the relation between the first projection content and the second projection content.

204: and generating a first instruction according to the first analysis result, and executing the first instruction in the first electronic device, wherein the first instruction is used for instructing the first electronic device to process the first projection content and the second projection content based on the position relation.

In the embodiment of the invention, after the second projection content is acquired, the second projection content and the first projection content are analyzed by combining the position relationship of the two projection areas, so that a first instruction for processing the two projection contents is obtained and is executed by the first electronic device. Therefore, after the first electronic device shares the projection content with the second electronic device through the data transmission channel, the projection content can be further processed, and the processing function of the electronic device on the projection content is increased.

Referring to fig. 3, a second flowchart of the data processing method according to the embodiment of the present invention is shown, where the data processing method shown in the flowchart illustrates that, when data generated by the same object at different times are stored in the first electronic device and the second electronic device, the latest data is updated to the electronic device that does not store the data by using the data processing method according to the embodiment of the present invention, and a process is as follows:

301: and acquiring the position relation of the first projection area and the second projection area. Wherein step 301 is the same as step 201, which is not described.

302: and acquiring second projection content from the second electronic equipment through the data transmission channel.

In this embodiment of the present invention, the second projection content is data generated by the first object at the second time, the first projection content is data generated by the first object at the first time, that is, the first projection content and the second projection content are data generated by the first object at different times, and the first time is earlier than the second time, so that the second projection content stored by the second electronic device is data obtained by updating the first projection content stored by the first electronic device, and at this time, the first electronic device needs to analyze the two projection contents to finally determine whether to update the first projection content to the second projection content.

303: and when the position relation indicates that the second projection area is positioned in the first projection area, matching the first projection content with the second projection content to determine whether the first projection content and the second projection content are the same.

In step 201, when the second projection area is located in the first projection area, it indicates that the second projection content is projected into the first projection area, and at this time, the first electronic device may further analyze whether the first projection content and the second projection content are the same.

In some examples of the embodiment of the present invention, when the first projection content and the second projection content are texts, the first electronic device may obtain key information in the first projection content and the second projection content through semantic analysis, and compare the key information to determine whether the first projection content and the second projection content are the same.

If the first projection content is: the sales of the product A is 300 ten thousand by No. 1/20 2014, and the second projection content is as follows: product a has a sales volume of 500 ten thousand in month 1 of 2014. The first electronic device obtains key information of the first projection content through semantic analysis, and the key information is as follows: product A-2014-1-20-sales amount 300 ten thousand, the key information of the second projection content is: product A-2014-1-sales 500 ten thousand. From these two pieces of key information, it can be known that the second projected content is the result of statistics of sales of product a in month 1 in 2014, while the first projected content is sales of product a by a certain day, which are significantly different, and the data of the second projected content is significantly more timely than the data of the first projected content.

In other examples of the embodiments of the present invention, the first projection content and the second projection content may also be images, and the first electronic device may determine whether the first projection content and the second projection content are the same through image comparison.

In other examples of embodiments of the present invention, the first projected content and the second projected content may be audio, and the first electronic device may determine whether the first projected content and the second projected content are the same through audio spectrum analysis.

304: and when the first projection content is not matched with the second projection content, obtaining a first analysis result indicating that the first projection content is different from the second projection content. The first analysis result may also indicate that the first electronic device updates the first projected content to the second projected content.

If the first electronic device determines that the first projection content and the second projection content are the same, the first electronic device does not update the first projection content and continues to project the first projection content into the first projection area.

305: and generating an updating instruction according to the first analysis result.

306: and executing an updating instruction to update the first projection content into the second projection content.

307: and deleting the first projection content projected to the first projection area, and projecting the second projection content to the first projection area through the first projection unit.

For example, in a meeting, the first electronic device of the presenter stores data such as a data report, and the data is projected as first projection content onto the projection plane through the first projection unit, and an area projected by the first projection unit on the projection plane is a first projection area. So that other persons in the conference can view the first projected content from the projection surface. If there is more updated information than the information shown in the first projection content among the other persons in the conference, the user may use his/her own second electronic device to project the stored updated information as the second projection content onto the projection surface, where the area projected by the second projection unit on the projection surface is the second projection area, as shown in fig. 4.

Wherein the first projected content in the first electronic device is projected into a first projection area, the second projected content in the second electronic device is projected into a second projection area, and it can be seen from the figure that the second projection area is located in the first projection area. At this time, the first electronic device can determine that the second projection area is located in the first projection area through distance analysis.

And the first projection content and the second projection content adopt a pie chart mode to record data, the pie chart is used as an image, and the first electronic equipment can determine whether the first projection content and the second projection content are the same or not through an image comparison mode. The first electronic device determines a first analysis result that the first projection content and the second projection content are different through comparison of the dividing lines on the pie chart, and the first electronic device generates an updating instruction according to the analysis result. The first electronic equipment runs the updating instruction, updates the first projection content into second projection content, deletes the first projection content projected into the first projection area, and projects the second projection content into the first projection area through the first projection unit.

It can be seen from the foregoing technical solutions that, in the data processing method provided in the embodiment of the present invention, the first projection area is used as a shared data area, the projection content of the shared data area can be analyzed, and in a case that the first projection content and the second projection content in the shared data area are different, the first electronic device can update the first projection content stored in the first electronic device to be the second projection content shared by the shared data area.

Referring to fig. 5, a third flowchart of a data processing method according to an embodiment of the present invention is shown, which illustrates that when an image is projected by a first electronic device and a second electronic device respectively as projection content, the image projected by the first electronic device is automatically changed, and the specific process is as follows:

501: and acquiring the position relation of the first projection area and the second projection area. Wherein step 501 is the same as step 201, which is not described.

502: and acquiring second projection content from the second electronic equipment through the data transmission channel.

In the embodiment of the present invention, the second projection content is a second image, and the first projection content is a first image, that is, the first electronic device and the second electronic device respectively project an image as the projection content.

503: and judging whether the display of the first object in the first image and the second object in the second image accords with a preset display relation or not based on the position relation. If not, go to step 504; if so, step 507 is performed.

The preset display relationship is a display relationship which the first object and the second object are correspondingly provided with in a real environment. If the first object is a person and the second object is a sofa, the preset display relationship between the first object and the second object should be: the person is back to the sofa. For another example, if the first object is a puppy and the second object is a bone, the preset display relationship between the first object and the second object is a direction from the mouth of the puppy to the bone.

504: and obtaining a first analysis result which shows that the first object and the second object do not accord with the preset display relation. When the first object and the second object do not conform to the preset display relationship, the first electronic device needs to change the display direction of the first electronic device so that the first object and the second object conform to the preset display relationship.

505: and generating a first instruction for changing the display direction of the first object according to the first analysis result.

506: the display orientation of the first object in the first projection area is altered.

Taking the above puppy and the bone as an example, when the mouth of the puppy faces away from the bone, the first electronic device generates a first instruction for changing the display direction of the puppy, and executes the first instruction to change the display direction of the puppy in the first projection area, so that the mouth of the puppy faces the bone, as shown in fig. 6, it is shown in fig. 6 that the first electronic device changes the display direction of the puppy, so that the mouth of the puppy faces the bone instead of facing away from the bone.

507: a first object and a second object are acquired.

508: judging whether the first object and the second object have an association relationship according to the preset object association relationship, if so, executing step 509; if not, step 510 is performed.

509: and adjusting the posture of the first object according to the association relation.

510: and finishing the operation.

The preset object association relationship is as follows: the interactive relationship of two objects specified in the interactive game stored in the first electronic device. After the first object and the second object are obtained, the first electronic device compares the specified objects in the interactive game to determine whether the obtained first object and the obtained second object are two objects specified by the interactive game, if so, step 309 is executed to adjust the posture of the first object according to the association relationship; and if not, the first electronic equipment ends the operation.

As shown in fig. 6, two objects, namely, a puppy and a bone, are shown, and when the first electronic device finds the interactive game in which the puppy bites the bone, the first electronic device adjusts the posture of the puppy, adjusts the posture of the puppy shown in fig. 6 when the puppy sits on the ground to a posture of jumping from the puppy, and shows an image of the puppy biting the bone shown in fig. 7.

It can be seen from the foregoing technical solutions that, the data processing method provided in the embodiment of the present invention can determine an object in the projected images of the first electronic device and the second electronic device, and adjust the posture of the first object in the first image projected by the first electronic device, so as to implement interaction between the first object and the second object in a certain virtual reality interactive game, that is, the data processing method provided in the embodiment of the present invention can design a virtual reality interactive game through a projection technology.

Referring to fig. 8, a fourth flowchart of a data processing method according to an embodiment of the present invention is shown, which illustrates how to supplement the first projection content projected by the first electronic device by using a projection method, and the specific process is as follows:

801: and acquiring the position relation of the first projection area and the second projection area. Wherein step 801 is the same as step 201 and is not described.

802: and acquiring second projection content from the second electronic equipment through the data transmission channel.

803: when the position relationship indicates that the first projection area and the second projection area overlap, a first position of the first projection content in the first projection area and a second position of the second projection content in the second projection area are acquired.

It can be understood that: projection parameters are set in the first electronic device and the second electronic device, and the projection parameters are used for indicating how the electronic devices display the projection content in the projection area, so that the first electronic device can determine a first position of the first projection content in the first projection area through the projection parameters of the first electronic device. Of course, the second electronic device may also determine the second position of the second projection content in the second projection area through its own projection parameters. The second position is sent to the first electronic device through the data transmission channel.

804: the second position is converted into a third position of the second projection content in the first projection area based on the positional relationship.

In some examples of the embodiment of the present invention, the position relationship may be determined by the first electronic device by analyzing the image acquired by the first acquisition unit, and as is known to those skilled in the art, the first electronic device may compare coordinates of a pixel point in the image as a third position of the second position in the first projection area.

In other examples of the embodiment of the present invention, the position relationship is obtained by comparing a center point formed on the projection plane by the axes of the first electronic device and the second electronic device with lengths of two projection areas, in this case, the first electronic device acquires the center point of the second projection area, and the position of the second projection area in the first projection area can be obtained by expanding the center point, and the second position of the second projection content in the second projection area is known, so that the second position can be converted into the third position by the position of the second projection area in the first projection area.

805: and comparing the first position with the third position to judge whether the first projection content and the second projection content are overlapped or not, so as to obtain a first analysis result for judging whether the first projection content and the second projection content are overlapped or not.

The first position is used for indicating the display position of the first projection content in the first projection area, and the third position is used for indicating the display position of the second projection content in the first projection area. When the first position and the third position overlap, the first projection content and the second projection content also overlap, so that the overlapped first projection content and the second projection content cannot be clearly distinguished, and therefore, the first electronic device needs to adjust the display of the first projection content and the second projection content so that the first projection content and the second projection content do not overlap.

806: and generating a typesetting instruction when the first analysis result shows that the first projection content and the second projection content are overlapped. The typesetting instruction is used for indicating the first projection content and the second projection content to be rearranged in a preset typesetting mode, namely, the first projection content and the second projection content are rearranged, so that the overlapped parts of the first projection content and the second projection content are separated.

807: and executing the typesetting instruction, and typesetting the first projection content and the second projection content based on a preset typesetting mode.

The preset typesetting mode is different based on the different types of the first projection content and the second projection content. The preset typesetting mode includes but is not limited to the following modes:

when the first projection content is characters and the second projection content is characters or multimedia information, the first projection content is displayed on the upper half part of the first projection area, and the second projection content is displayed on the lower half part of the first projection area;

and when the first projection content and the second projection content are images and the first projection content and the second projection content are half images of a complete image, splicing the first projection content and the second projection content into the complete image.

808: and projecting the typeset first projection content and the typeset second projection content into a first projection area through a first projection unit.

The first electronic device may further store the second projection content, and copy the projection content in a projection manner, for example, when the first electronic device plays a picture in an album through projection, the second electronic device projects the picture stored in the second electronic device into the first projection area, and the first electronic device may add the picture into the album.

The points to be explained are: when the first analysis result indicates that the first projection content and the second projection content do not overlap, the first electronic device displays the second projection content according to the position of the second projection area in the first projection area, as shown in fig. 9.

By applying the data processing method provided by the embodiment of the invention, the first electronic device can judge the positions of the first projection content and the second projection content, and when the first projection content and the second projection content are judged to be overlapped, the first projection content and the second projection content are automatically typeset. In addition, the first electronic device and the second electronic device can also share the projection content in a projection mode, and the second projection content of the second electronic device is shared to the first electronic device.

Certainly, the first projected content in the first electronic device is copied by the second electronic device as a shared content, as shown in fig. 10, it is described how the second electronic device obtains the first projected content from the first electronic device in a projection manner, where the first projected content includes first text content and first option content, the first option content includes at least one operation on the first text content, and the second projected content is a first graphic, and the first graphic is used for selecting one operation included in the first option content. The data processing method shown in fig. 10 may include the steps of:

1001: and acquiring the position relation of the first projection area and the second projection area. Wherein step 1001 is the same as step 201, which is not described.

1002: and acquiring second projection content from the second electronic equipment through the data transmission channel.

1003: when the position relationship indicates that the first projection area and the second projection area overlap, a first position of the first projection content in the first projection area and a second position of the second projection content in the second projection area are acquired.

1004: the second position is converted into a third position of the second projection content in the first projection area based on the positional relationship.

1005: and comparing the first position with the third position to judge whether the first projection content and the second projection content are overlapped or not, so as to obtain a first analysis result for judging whether the first projection content and the second projection content are overlapped or not.

Step 1002 to step 1005: as with steps 802 through 805, this is not illustrated.

1006: and when the first analysis result shows that the first projection content and the second projection content are overlapped, obtaining the operation selected by the first graph according to the third position. The operation selected by the first graph is an operation to be executed on the first projection content by the first electronic equipment.

1007: and generating a first instruction based on the selected operation, and executing the first instruction on the first projection content to execute the selected operation of the second projection content on the first projection content.

As shown in fig. 11, the first electronic device projects a certain video as first projection content into a first projection area, and three operations A, B and C operable for the first projection content are projected in the first projection area, the second electronic device projects a second projection area in which the second projection content is a rectangle, and the operation C is selected. The first electronic device generates a first instruction corresponding to the C operation, and the first electronic device executes the first instruction to perform the C operation on the first projection content.

For example, when the operation C is a copy operation, the operation C is selected from the first image to indicate that the second electronic device wants to acquire the video file currently projected by the first electronic device, and the first electronic device sends the video file to the second electronic device through the data transmission channel to implement data sharing.

Referring to fig. 12, a sixth flowchart of a data processing method according to an embodiment of the present invention is shown, illustrating automatic adjustment of an image when the first projection content and the second projection content are images, where the method may include the following steps:

1201: and acquiring the position relation of the first projection area and the second projection area.

1202: and acquiring second projection content from the second electronic equipment through the data transmission channel.

In the embodiment of the present invention, the first projection content is a first image, the first image is a half image of the third image, and the second projection content is a second image. The second image may be the other half of the third image, or may be another image, which is determined by the user of the second electronic device.

1203: and analyzing the first image and the second image based on the position relation to obtain a first analysis result.

In the embodiment of the invention, the analysis of the first image and the second image mainly comprises the step of analyzing the positions of the two images so as to judge whether the two images are spliced into one image. For example, when the first image is displayed on the left of the second image, the right edge of the first image and the left edge of the second image are coincident, which indicates that the first image and the second image are spliced into one image, and if the right edge of the first image is far away from the left edge of the second image, which indicates that the first image and the second image are not spliced into one image; if a portion of the first image overlaps a portion of the second image, it also indicates that the first image and the second image are not stitched into one image.

1204: and when the first analysis result shows that the first image and the second image are overlapped or separated, generating a projection adjusting instruction.

When the first analysis result shows that the first image and the second image are overlapped or separated, the first image and the second image are not spliced into one image, and at the moment, the first electronic equipment needs to produce a projection adjusting instruction, wherein the projection adjusting instruction is at least used for adjusting display parameters of the image projected by any electronic equipment.

Such as a projection adjustment instruction for adjusting a display parameter of a first image projected by a first electronic device or for adjusting a display parameter of a second image projected by a second electronic device. Of course, the projection adjustment instruction is also used to simultaneously adjust the display parameters of the first image projected by the first electronic device and the display parameters of the second image projected by the second electronic device.

1205: and adjusting the image projected by any electronic equipment according to the display parameters so that the adjusted first image and the second image are spliced into a fourth image on the projection surface. Any one of the electronic devices is an electronic device for adjusting the display parameters by the projection adjustment instruction, and the electronic device splices the first image and the second image into one image (a fourth image) by executing the projection adjustment instruction.

1206: and matching the fourth image and the third image, wherein when the fourth image and the third image are matched, the first image and the second image are spliced into the third image, namely the second image is the other half image of the third image.

Taking fig. 13 as an example, the first electronic device projects the first image in the first projection area, the second electronic device projects the second image in the second projection area, and the first image and the second image are separated. On the basis, the first electronic device generates a projection adjustment instruction for adjusting the first image and the second image, and sends the projection adjustment instruction to the second electronic device through the data transmission channel. The first electronic device and the second electronic device respectively execute the projection adjustment instruction to adjust the self-projected images, the adjusted first image and the second image are spliced into a fourth image, and the fourth image is matched with the third image through matching, so that the second image is the other half of the third image.

In some examples of the embodiment of the present invention, the first image includes a first key for performing secure authentication on the device, the second image includes a second key for performing secure authentication on the device, and a third key matching the first key is included in another half of the third image, that is, when the first image and the other image are spliced into the third image, it indicates that the electronic device projecting the other image is a secure device authenticated by the first electronic device, and the two electronic devices may perform the above operations such as data sharing. Therefore, when the second image projected by the second electronic device and the first image projected by the first electronic device are spliced into the third image, it is indicated that the second key is the same as the third key, and the security device that the second electronic device and the first electronic device pass the key authentication can perform the above-mentioned operations such as data sharing with the first electronic device.

In other examples of the embodiment of the present invention, the third image is a frame image in a video played by the first electronic device, and when the first image and the second image are spliced into the third image, the first electronic device may further call the corresponding video to play, and a process of the third image may be shown in fig. 14, and based on fig. 12, the method may further include the following steps:

1207: and acquiring a video corresponding to the third image in the first electronic equipment. In the embodiment of the invention, the first electronic device can record the video name corresponding to each frame of image, and after the third image is spliced, the video corresponding to the third image can be found through the video name.

1208: and selecting a playing application corresponding to the video from the first electronic equipment, and indicating the first electronic equipment to call the playing application.

1209: and loading the video into a playing application, and displaying the played video in the first projection area.

Based on the above scheme, the first electronic device can call the video corresponding to the third image after the third image is spliced, and start the playing application to play the video, so that the video is obtained based on image matching and automatically played. And the embodiment of the invention can play the video from the starting position of the video when playing the video. Of course, it may also continue to play the video starting from the playing position in the video where the third image is located.

In addition, when the first electronic device displays the played video in the first projection area, the first electronic device may further execute a corresponding instruction by detecting an operation on the first projection area, as shown in fig. 15, and on the basis of fig. 14, the method may further include the following steps:

1210: the depth information of the operation body is acquired by detecting a first deformation amount of the structured light projected by the first projection unit.

The first deformation quantity is a deformation quantity which enables the structured light to deform when the operation body moves in the first projection area. The first deformation quantity is larger when the operation body is closer to the first projection unit; when the operation body is farther from the first projection unit, the first deformation amount is smaller, so that the first electronic device binds the first deformation amount with the depth information, and the depth information of the operation body is acquired through detection of the first deformation amount.

1210: when the depth information of the operation body is the same as the depth information of the projection plane, the second and third deformation amounts of the structured light are detected.

The depth information of the projection surface is acquired by a first acquisition unit in the first electronic device, when the depth information of the operation body is the same as the depth information of the projection surface, the operation body is indicated to operate on the projection surface in the first projection area, and the first electronic device needs to determine what operation is performed by the operation body at the moment, and the determination of the operation can be judged by the second deformation amount and the third deformation amount.

1211: and determining the trigger operation of the operation body through the second deformation quantity and the third deformation quantity, and generating a second instruction corresponding to the trigger action.

In the embodiment of the invention, if the second deformation amount indicates that the variation trend is changed from large to small, the third deformation amount indicates that the variation trend is changed from small to large, and the variation distance of each deformation amount is basically the same, the first electronic device determines that the operation body executes the click operation, and generates the second instruction corresponding to the click operation.

The currently generated second instruction is related to a second instruction generated when the clicking operation is executed before, and if the previously generated second instruction is a playing instruction, the currently generated second instruction is a pausing instruction; and if the previously generated second instruction is a pause instruction, the currently generated second instruction is a play instruction.

If the second deformation variable is zero and the third deformation variable is a deformation variable of a plurality of light beams in the structured light, it indicates that the operating body is dragging a video file from the playlist to be played by the first electronic device, and at this time, the first electronic device generates a second instruction for retrieving the video file and adding the video file to the playing application.

In the embodiment of the present invention, the first projection area and the second projection area are overlapped, so when the second instruction is executed, the first electronic device first needs to determine the position of the trigger operation, and particularly when the trigger operation is a single-click operation, if the position of the trigger operation is the overlapped area of the first projection area and the second projection area, both the first electronic device and the second electronic device execute the second instruction, which causes the second instruction to be executed twice, so that the result executed by the first electronic device is different from the result executed by the trigger operation. When the positions of the trigger operations are different, the operations performed by the first electronic device can be referred to in steps 1212 and 1213.

1212: and when the position of the trigger operation is located in the overlapping area of the first projection area and the second projection area, sending an execution prohibition instruction to the second electronic equipment through the data transmission channel, and instructing the second electronic equipment to suspend executing the second instruction.

1213: and when the position of the trigger operation is located in the area where the first projection area is not overlapped with the second projection area, executing a second instruction by the first electronic equipment.

Corresponding to the above method embodiment, an embodiment of the present invention provides a data processing apparatus for processing data between a first electronic device and a second electronic device, where the first electronic device includes a first projection unit, the first electronic device projects a first projection area on a projection surface through the first projection unit and projects first projection content in the first projection area through the first projection unit, the second electronic device includes a second projection unit, the second electronic device projects a second projection area on the projection surface through the second projection unit and projects second projection content in the second projection area through the second projection unit, and a data transmission channel is established between the first electronic device and the second electronic device.

The data processing apparatus 900 is applied to a first electronic device, and the structure diagram thereof shown in fig. 16 includes: a first acquisition unit 901, a second acquisition unit 902, an analysis unit 903, a generation unit 904, and an execution unit 905, wherein,

In some examples of the embodiment of the present invention, the first electronic device further includes a first acquisition unit, the first acquisition unit acquires a projection image formed by the first projection area and the second projection area on the projection surface, and the first acquisition unit 901 may obtain a positional relationship between the first projection area and the second projection area through analysis of the projection image. However, the acquisition field of view of the first acquisition unit is limited, and when the first electronic device is located at a smaller distance from the projection surface, the larger the first projection area formed on the projection surface, the first acquisition unit may acquire only a partial area of the first projection area, so that the first acquisition unit 901 cannot know the position relationship between the first projection area and the second projection area from the projection image.

In other examples of the embodiments of the present invention, the first obtaining unit 901 may determine the position relationship between the first projection area and the second projection area by determining whether a distance between center points of the first projection area and the second projection area is less than half of a sum of lengths of the first projection area and the second projection area.

For example, if the distance between the center points of the first projection unit and the second projection unit is d, the length of the first projection area is a, and the length of the second projection area is b, if d is smaller than (a + b)/2, the first obtaining unit 901 may determine that the first projection area and the second projection area overlap; if d is equal to (a + b)/2, the first acquisition unit 901 may determine that the second projection region is not in the first projection region and one side of the second projection region overlaps one side of the first projection region; if d is greater than (a + b)/2, the first acquisition unit 901 may determine that the first projection region and the second projection region are separated; if d is determined to be less than a/2 and d is greater than b/2 on the basis that d is less than (a + b)/2, the first acquisition unit 901 may determine that the second projection region is located in the first projection region.

The length of the first projection area and the length of the second projection area may be determined by projection parameters of the respective projection units, and the first obtaining unit 901 may obtain, from the second electronic device through the data transmission channel, various parameters of the second projection area, where the various parameters include the length of the second projection area.

A second obtaining unit 902, configured to obtain second projection content from a second electronic device through a data transmission channel. The second projection content is a content projected on the projection surface by the second projection unit, and may be a segment of text, data, or an image, and is specifically determined by a user of the second electronic device according to an application scenario.

An execution unit 905 is configured to execute the first instruction in the first electronic device.

In the embodiment of the present invention, after the second projection content is acquired, the second projection content and the first projection content are analyzed in combination with the position relationship between the two projection areas, so as to obtain a first instruction for processing the two projection contents, and the execution unit 905 executes the first instruction on the first electronic device. In this way, after the first electronic device uses the data processing apparatus provided by the embodiment of the present invention to share the projection content with the second electronic device through the data transmission channel, the projection content can be further processed, and the processing function of the electronic device on the projection content is increased.

A first application scenario of the data processing apparatus provided in the embodiment of the present invention is as follows: the first projection content is data generated by the first object at a first time, the second projection content is data generated by the first object at a second time, and the first time is earlier than the second time, so that the data processing apparatus 900 may update the latest data to an electronic device that does not store the data when the data generated by the same object at different times is stored in the first electronic device and the second electronic device.

In a first application scenario, the analyzing unit 903 analyzes the first projection content and the second projection content based on the position relationship to obtain a first analysis result, and includes:

and when the position relation indicates that the second projection area is positioned in the first projection area, matching the first projection content with the second projection content, and when the first projection content is not matched with the second projection content, obtaining a first analysis result indicating that the first projection content is different from the second projection content.

In some examples of the first application scenario, when the first projection content and the second projection content are words, the analysis unit 903 may obtain key information in the first projection content and the second projection content through semantic analysis, and compare the key information to determine whether the first projection content and the second projection content are the same.

If the first projection content is: the sales of the product A is 300 ten thousand by No. 1/20 2014, and the second projection content is as follows: product a has a sales volume of 500 ten thousand in month 1 of 2014. The analysis unit 903 obtains key information of the first projection content through semantic analysis, where the key information is: product A-2014-1-20-sales amount 300 ten thousand, the key information of the second projection content is: product A-2014-1-sales 500 ten thousand. From these two pieces of key information, it can be known that the second projected content is the result of statistics of sales of product a in month 1 in 2014, while the first projected content is sales of product a by a certain day, which are significantly different, and the data of the second projected content is significantly more timely than the data of the first projected content.

In other examples of the first application scenario, the first projection content and the second projection content may also be images, and the analysis unit 903 may determine whether the first projection content and the second projection content are the same through image comparison.

In other examples of the first application scenario, the first projection content and the second projection content may be audio, and the analysis unit 903 may determine whether the first projection content and the second projection content are the same through audio spectrum analysis.

Accordingly, the generating unit 904 may generate the update instruction according to the first analysis result. The execution unit 905 executes a first instruction in the first electronic device, including: and executing an updating instruction, updating the first projection content into second projection content, deleting the first projection content projected to the first projection area, and projecting the second projection content to the first projection area through the first projection unit.

In a second application scenario provided in the embodiment of the present invention, the first projection content is a first image, and the second projection content is a second image. In a second application scenario, when the data processing apparatus 900 according to the embodiment of the present invention projects one image as projection content through each of the first electronic device and the second electronic device, the image projected by the first electronic device is automatically changed.

In the second application scenario, the analysis unit 903 may determine whether the display of the first object in the first image and the second object in the second image conforms to a preset display relationship based on the positional relationship. And if not, obtaining a first analysis result indicating that the first object and the second object do not accord with the preset display relationship.

When the first object and the second object do not conform to the preset display relationship, the data processing apparatus 900 needs to change its display direction so that the first object and the second object conform to the preset display relationship. At this time, the generating unit 904 generates a first instruction for changing the display direction of the first object according to the first analysis result. The first instruction is then executed by the execution unit 905 to alter the display orientation of the first object in the first projection region.

In a second application scenario, the data processing apparatus 900 provided in the embodiment of the present invention may further include, on the basis of fig. 16: a third acquiring unit 906 and an adjusting unit 907, as shown in fig. 17, wherein:

a third acquiring unit 906 for acquiring the first object and the second object.

The adjusting unit 907 is configured to adjust the posture of the first object according to the association relationship when the first object and the second object have the association relationship according to the preset object association relationship.

In the embodiment of the present invention, the preset object association relationship is: the interactive relationship of two objects specified in the interactive game stored in the first electronic device. After the first object and the second object are acquired, the objects designated in the interactive game are compared to determine whether the acquired first object and the acquired second object are two objects designated in the interactive game, and if so, the adjusting unit 907 is triggered to adjust the posture of the first object according to the association relationship.

In a third application scenario of the embodiment of the present invention, it is described how the data processing apparatus 900 supplements, in a projection manner, the first projection content projected by the first electronic device, where when a position relationship of the analysis unit 903 in the data processing apparatus 900 indicates that the first projection area and the second projection area overlap, a schematic structural diagram of the analysis unit 903 in the data processing apparatus 900 is shown in fig. 18, and the configuration diagram may include: an acquisition subunit 9031, a conversion subunit 9032, and a comparison subunit 9033, wherein,

an acquiring subunit 9031, configured to acquire a first position of the first projection content in the first projection area, and a second position of the second projection content in the second projection area.

It can be understood that: projection parameters are set in the first electronic device and the second electronic device, and the projection parameters are used for instructing the electronic devices how to display the projection content in the projection area, so that the acquiring subunit 9031 may determine the first position of the first projection content in the first projection area by using its own projection parameters. Of course, the second electronic device may also determine the second position of the second projection content in the second projection area through its own projection parameters. The second position is sent to the acquiring subunit 9031 through the data transmission channel.
