[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0027] The embodiments of the present application provide a control method and device for a near-eye display device, and a near-eye display device, wherein the control method for a near-eye display device can be applied to a near-eye display device.

[0028] Exemplarily, the near-eye display device may include VR glasses, AR glasses, etc., which are not limited here.

[0029] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0030] See also Figure 1 , Figure 1 It is a flow chart of a control method of a near-eye display device provided in an embodiment of the present application. It should be noted that the control method of a near-eye display device provided in an embodiment of the present application can be used for a near-eye display device.

[0031] like Figure 1 As shown, the control method of the near-eye display device includes steps S101 to S103.

[0032] S101. When a projection unit of a near-eye display device is in a projection state, a projection parameter adjustment operation is obtained.

[0033] In some embodiments, the near-eye display device may have a projection function. Exemplarily, the near-eye display device includes a projection unit. When the user has a projection demand for the corresponding projection content, the corresponding projection content can be projected through the projection unit of the near-eye display device. For example, the near-eye display device can project the corresponding projection content on the display screen of the near-eye display device through the projection unit of the near-eye display device according to the projection demand of the user, so as to present the display effect of displaying the projection content through the near-eye display device. For example, the projection unit of the near-eye display device can be arranged between the eyes of the user wearing the near-eye display device and the display screen of the near-eye display device, and the projection unit can project the corresponding projection content on the display screen. Of course, it is not limited to this. For example, the projection unit of the near-eye display device can be the display screen of the near-eye display device, and the near-eye display device can send the corresponding projection content to the display screen, so that the display screen is displayed according to the projection content, which is not limited here. When the near-eye display device is at least one of smart glasses such as VR glasses, AR glasses, etc., the display screen may include lenses of the near-eye display device, frames of the near-eye display device, etc., which are not limited here.

[0034] For example, when the projection unit of the near-eye display device is in the projection state, the user can perform corresponding projection parameter adjustment operations on the near-eye display device according to the projection requirements of the projection content. For example, the projection parameter adjustment operation may include a user's touch operation, a user's gesture interaction operation, etc., but is certainly not limited thereto and is not limited here.

[0035] For example, the user's projection requirements for different projection contents may be different. In some embodiments, the projection parameters include at least one of the projection distance and the projection size. For example, when the user projects a movie with the help of the projection unit of the near-eye display device, the projection requirement for the movie may be to project the movie at a larger projection distance and / or a larger projection size, then the projection unit of the near-eye display device requires a larger projection parameter when the user projects the movie; when the user projects the chat information with the help of the projection unit of the near-eye display device, the projection requirement for the chat information may be to project the chat content at a smaller projection distance and / or a smaller projection size, then the projection unit of the near-eye display device requires a smaller projection parameter when the user projects the chat content. Of course, the projection parameters are not limited to the projection distance or projection size, and are not limited here. Based on this, according to the user's different projection requirements for different projection contents, the user can adjust the projection parameters of the projection unit of the near-eye display device to adjust the projection parameters of the projection unit of the near-eye display device. Of course, it is not limited to this. For example, different users may also have different projection requirements for projection content. For example, both the first user and the second user need to project a movie with the help of a projection unit of a near-eye display device, wherein the first user may have a greater demand for the projection parameters of the movie, while the second user may have a smaller demand for the projection parameters of the movie. Based on this, different users may perform projection parameter adjustment operations on the near-eye display device according to their projection requirements for the projected content, so as to adjust the projection parameters of the projection unit of the near-eye display device, which is not limited here.

[0036] In some embodiments, when a user performs a projection parameter adjustment operation on a near-eye display device, the near-eye display device may obtain the user's projection parameter adjustment operation so as to subsequently adjust the projection parameters of the projection unit according to the user's projection parameter adjustment operation.

[0037] Based on this, when the projection unit of the near-eye display device is in the projection state, obtaining the user's projection parameter adjustment operation is conducive to improving the convenience of adjusting the projection parameters of the near-eye display device.

[0038] S102: Determine a target projection parameter of a projection unit according to at least one of operation position information and hand posture information corresponding to a projection parameter adjustment operation.

[0039] Exemplarily, at least one of the operation position information and hand posture information corresponding to the projection parameter operation can be determined according to the projection parameter adjustment operation of the user. For example, the operation position information may include the position of the user touching the near-eye display device, the position of the user's hand relative to the near-eye display device, etc., which are not limited here. The hand posture information may include the type of finger of the user touching the near-eye display device, the user's gesture, etc., which are not limited here.

[0040] For example, when the operation position information corresponding to the projection parameter operation is different, the user's projection parameter requirements for the projection unit may be different. Alternatively, when the hand posture information corresponding to the projection parameter operation is different, the user's projection parameter requirements for the projection unit may also be different. Based on this, when the user's projection parameter adjustment operation is obtained, the user's projection parameter requirements for the projection unit may be determined based on at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation. Based on the user's projection parameter requirements for the projection unit, the projection parameters of the projection unit are adjusted to determine the target projection parameters of the projection unit.

[0041] In this way, by determining the target projection parameters of the projection unit according to at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation, the near-eye display device can flexibly determine the target projection parameters of the projection unit according to at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation, which is conducive to improving the convenience and flexibility of adjusting the projection parameters of the near-eye display device.

[0042] In some embodiments, when it is determined that the distance between two fingers of the user increases according to at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation, the current projection parameter of the projection unit is increased to obtain the target projection parameter; when it is determined that the distance between two fingers of the user decreases according to at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation, the current projection parameter of the projection unit is reduced to obtain the target projection parameter.

[0043] Exemplarily, during the process of the user performing a projection parameter adjustment operation on the near-eye display device, the user may continuously obtain at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation.

[0044] For example, when the user performs a projection parameter adjustment operation on the near-eye display device, the near-eye display device can be touched. For example, the user touches the near-eye display device with two fingers. One finger of the user continuously touches the same position of the near-eye display device, and the other finger of the user moves to touch the near-eye display device, then the near-eye display device can obtain the operation position information corresponding to the projection parameter adjustment operation. The operation position information corresponding to one finger of the user remains unchanged during the process of the user performing the projection parameter adjustment operation on the near-eye display device, and the operation position information corresponding to the other finger of the user changes during the process of the user performing the projection parameter adjustment operation on the near-eye display device. In the process of the user performing the projection parameter adjustment operation on the near-eye display device, the distance between the two fingers of the user can be determined according to the operation position information corresponding to each of the two fingers of the user. In the case where it is determined that the distance between the two fingers of the user increases according to the operation position information corresponding to each of the two fingers of the user, it can be determined that the user has a greater demand for the projection parameters of the projection unit, and the current projection parameters of the projection unit can be increased to obtain the target projection parameters. In the case where it is determined that the distance between the two fingers of the user is reduced according to the operation position information corresponding to each of the two fingers of the user, it can be determined that the user has a small demand for the projection parameters of the projection unit, and the current projection parameters of the projection unit can be reduced to obtain the target projection parameters. Of course, this is not limited to this. For example, when the user touches the near-eye display device with two fingers, both fingers of the user can move to touch the near-eye display device, and the distance between the two fingers of the user is determined to increase or decrease according to the operation position information corresponding to each of the two fingers of the user, so as to increase or decrease the current projection parameters of the projection unit and obtain the target projection parameters. This is not limited here.

[0045] For example, when the user performs a projection parameter adjustment operation on the near-eye display device, the user can perform gesture interaction on the near-eye display device. For example, the near-eye display device can obtain the user's hand image when the user performs gesture interaction on the near-eye display device within a preset time. According to the user's hand image when the user performs gesture interaction on the near-eye display device within the preset time. According to the user's hand image when the user performs gesture interaction on the near-eye display device, determine the change of the user's hand posture information. In the case where it is determined according to the user's hand posture information that the distance between the user's two fingers increases, it can be determined that the user has a greater demand for the projection parameters of the projection unit, and the current projection parameters of the projection unit can be increased to obtain the target projection parameters. In the case where it is determined according to the user's hand posture information that the distance between the user's two fingers decreases, it can be determined that the user has a lesser demand for the projection parameters of the projection unit, and the current projection parameters of the projection unit can be reduced to obtain the target projection parameters. Of course, it is not limited to this. For example, when a user touches the near-eye display device with two fingers, the near-eye display device can acquire the user's hand image to determine whether the distance between the two fingers of the user increases or decreases based on the acquired user's hand image, so as to increase or decrease the current projection parameters of the projection unit and obtain the target projection parameters. This is not limited here.

[0046] For example, when the user adjusts the projection parameters of the near-eye display device, the user can perform touch operations and gesture interactions on the near-eye display device. When the user touches the near-eye display device with two fingers, for example, one of the fingers stops touching the near-eye display device while moving to touch the near-eye display device, and the distance between the two fingers of the user continues to increase or decrease, or when the user performs gesture interaction with the near-eye display device, the two fingers of the user touch the near-eye display device, and the distance between the two fingers of the user continues to increase or decrease. In this case, the operation position information and hand posture information corresponding to the two fingers of the user can be combined to determine whether the distance between the two fingers of the user increases or decreases, so as to increase or decrease the current projection parameters of the projection unit and obtain the target projection parameters. Of course, it is not limited to this and is not limited here.

[0047] In this way, the distance between the two fingers of the user is determined to be farther or closer according to at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation, and the current projection parameters of the projection unit are adjusted up or down to obtain the target projection parameters. The near-eye display device can flexibly adjust the projection parameters of the near-eye display device based on the user's different projection parameter adjustment operations on the near-eye display device, and select appropriate projection parameter adjustment basis such as at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation, to adjust the projection parameters of the near-eye display device, which is conducive to improving the convenience and flexibility of adjusting the near-eye display device.

[0048] In some embodiments, the projection parameter corresponding to the projection parameter adjustment operation is determined to be the projection size and / or projection distance based on at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation; when the projection parameter corresponding to the projection parameter adjustment operation is the projection size, the target projection size of the projection unit is determined based on at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation; when the projection parameter corresponding to the projection parameter adjustment operation is the projection distance, the target projection distance of the projection unit is determined based on at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation.

[0049] Exemplarily, the projection parameters of the projection unit may include at least one of a projection size and a projection distance. For example, when a user adjusts the projection parameters of the near-eye display device, the user may have different adjustment requirements for different projection parameters, and the user needs to adjust the different projection parameters respectively. Accordingly, the near-eye display device needs to identify the projection parameters that the user needs to adjust. For example, the projection parameters that the user needs to adjust are identified as projection size and / or projection distance.

[0050] For example, the projection parameter corresponding to the projection parameter adjustment operation can be determined as the projection size and / or the projection distance according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation. In some embodiments, an association relationship between at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation and the projection parameter corresponding to the projection parameter adjustment operation being the projection size and / or the projection distance can be established. In some embodiments, when it is determined that the user's operation position of the near-eye display device is in the first operation sub-range according to the operation position information corresponding to the projection parameter adjustment operation, the projection parameter corresponding to the projection parameter adjustment operation is determined to be the projection size. The first operation sub-range is, for example, the upper display area of ​​the lens in the near-eye display device, which is of course not limited to this and is not limited here. When it is determined that the user's operation position of the near-eye display device is in the second operation sub-range according to the operation position information corresponding to the projection parameter adjustment operation, the projection parameter corresponding to the projection parameter adjustment operation is determined to be the projection distance. The second operation sub-range is different from the first operation sub-range, and the second operation sub-range is, for example, the lower display area of ​​the lens in the near-eye display device, which is of course not limited to this and is not limited here. When it is determined that the user's operation position on the near-eye display device is in the first operation sub-range and the second operation sub-range according to the operation position information corresponding to the projection parameter adjustment operation, the projection parameters corresponding to the projection parameter adjustment operation are determined to be the projection size and the projection distance. In some embodiments, when the user touches the near-eye display device with two fingers to perform the projection parameter adjustment operation, a continuous multi-frame image of the two fingers of the user when touching the near-eye display device can be obtained to determine the hand posture information corresponding to the projection parameter adjustment operation. For example, the near-eye display device can identify the fingerprint information of the two fingers of the user according to the continuous multi-frame image, so as to identify the first finger of the user and the second finger of the user in combination with the fingerprint information of the first finger of the user and the fingerprint information of the second finger of the user. And according to the continuous multi-frame image, determine the position change of the first finger of the user and the position change of the second finger of the user. If the position change of the first finger of the user in the continuous multi-frame image is small, it can be determined that the fixed touching finger of the user on the near-eye display device is the first finger. If the position change of the second finger of the user in the continuous multi-frame image is large, it can be determined that the mobile touching finger of the user on the near-eye display device is the second finger. In an exemplary manner, when it is determined that the user's fixed touching finger on the near-eye display device is the first finger and the moving touching finger is the second finger according to the hand posture information corresponding to the projection parameter adjustment operation, the projection parameter corresponding to the projection parameter adjustment operation is determined to be the projection size. When it is determined that the user's fixed touching finger on the near-eye display device is the second finger and the moving touching finger is the first finger according to the hand posture information corresponding to the projection parameter adjustment operation, the projection parameter corresponding to the projection parameter adjustment operation is determined to be the projection distance.Of course, it is not limited to this. For example, taking the first finger as the thumb and the second finger as the index finger as an example, when it is determined based on multiple consecutive frames of images that the user touches the near-eye display device with the thumbs and index fingers of the left and right hands, and when it is determined that the fixed touching finger of the left hand is the thumb and the fixed touching finger of the right hand is the index finger, the projection parameters corresponding to the projection parameter adjustment operation are determined to be the projection size and the projection distance, and no limitation is made here. Based on this, according to at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation, it is determined that the projection parameters corresponding to the projection parameter adjustment operation are the projection size and / or the projection distance, which can clarify the projection parameters that the user needs to adjust, and can flexibly clarify the projection parameters that the user needs to adjust based on at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation, which is conducive to improving the accuracy and flexibility of determining the user's adjustment requirements for the projection parameters of the near-eye display device, and is conducive to improving the accuracy of adjusting the projection parameters of the near-eye display device.

[0051] In some embodiments, when it is determined that the projection parameter corresponding to the projection parameter adjustment operation is the projection size, the target projection size of the projection unit can be determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation. For example, when it is determined that the distance between the two fingers of the user increases according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation, the current projection size of the projection unit is increased to obtain the target projection size. When it is determined that the distance between the two fingers of the user decreases according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation, the current projection size of the projection unit is reduced to obtain the target projection size. Based on this, when the projection parameter corresponding to the projection parameter adjustment operation is the projection size, the target projection size of the projection unit is determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation, and the near-eye display device can flexibly determine the target projection size of the projection unit according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation, which is conducive to improving the convenience and flexibility of adjusting the projection size of the near-eye display device.

[0052] In some embodiments, when it is determined that the projection parameter corresponding to the projection parameter adjustment operation is the projection distance, the target projection distance of the projection unit can be determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation. For example, when it is determined that the distance between the two fingers of the user increases according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation, the current projection distance of the projection unit is increased to obtain the target projection distance. When it is determined that the distance between the two fingers of the user decreases according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation, the current projection distance of the projection unit is reduced to obtain the target projection distance. Based on this, when the projection parameter corresponding to the projection parameter adjustment operation is the projection distance, the target projection distance of the projection unit is determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation, and the near-eye display device can flexibly determine the target projection distance of the projection unit according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation, which is conducive to improving the convenience and flexibility of adjusting the projection distance of the near-eye display device.

[0053] Exemplarily, the near-eye display device includes a frame touch area. For example, the frame touch area can be set on the frame of the near-eye display device, and the frame touch area can be used as an area for the user to adjust the projection parameters of the near-eye display device.

[0054] In some embodiments, when it is determined that the touch position of at least one finger of the user is in the first touch sub-area of ​​the frame touch area according to the operation position information corresponding to the projection parameter adjustment operation, the projection parameter corresponding to the projection parameter adjustment operation is determined to be the projection size; when it is determined that the touch position of at least one finger of the user is in the second touch sub-area of ​​the frame touch area according to the operation position information corresponding to the projection parameter adjustment operation, the projection parameter corresponding to the projection parameter adjustment operation is determined to be the projection distance.

[0055] For example, Figure 2 or Figure 3 As shown, the upper half of the frame touch area can be used as the first touch sub-area of ​​the frame touch area. When it is determined that the touch position of at least one finger of the user is in the upper half of the frame touch area according to the operation position information corresponding to the projection parameter adjustment operation, the projection parameter corresponding to the projection parameter adjustment operation can be determined as the projection size.

[0056] like Figure 2As shown, when it is determined that the projection parameter corresponding to the projection parameter adjustment operation is the projection size, if it is determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation that one finger of the user long presses the first touch sub-area of ​​the touch area of ​​the touch frame, and another finger of the user moves the first touch sub-area of ​​the touch area of ​​the touch frame, and the distance between the two fingers of the user increases, then the current projection size of the projection unit is increased to obtain the target projection size. Of course, it is not limited to this and is not limited here.

[0057] like Figure 3 As shown, when it is determined that the projection parameter corresponding to the projection parameter adjustment operation is the projection size, if it is determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation that one finger of the user long presses the first touch sub-area of ​​the touch area of ​​the touch frame, and another finger of the user moves to touch the first touch sub-area of ​​the touch area of ​​the touch frame, and the distance between the two fingers of the user is close, then the current projection size of the projection unit is increased to obtain the target projection size. Of course, it is not limited to this and is not limited here.

[0058] In an exemplary embodiment, after determining that the projection parameter corresponding to the projection parameter adjustment operation is the projection size according to the operation position information corresponding to the projection parameter adjustment operation, the operation position information corresponding to the projection parameter adjustment operation can be continuously obtained to determine whether the distance between the two fingers of the user increases or decreases; or it can be converted to obtain the hand posture information corresponding to the projection parameter adjustment operation to determine whether the distance between the two fingers of the user increases or decreases. Of course, it is not limited to this. For example, after determining that the projection parameter corresponding to the projection parameter adjustment operation is the projection size according to the operation position information corresponding to the projection parameter adjustment operation, one of the user's fingers may leave the first touch sub-area when moving the first touch sub-area of ​​the touch area of ​​the touch frame. However, the distance between the two fingers of the user continues to increase or decrease. In this case, the operation position information corresponding to the projection parameter adjustment operation and the hand posture information can be combined to determine whether the distance between the two fingers of the user increases or decreases. This is not limited here.

[0059] For example, Figure 4 or Figure 5 As shown, the lower half of the frame touch area can be used as the second touch sub-area of ​​the frame touch area. When it is determined that the touch position of at least one finger of the user is in the lower half of the frame touch area according to the operation position information corresponding to the projection parameter adjustment operation, it can be determined that the projection parameter corresponding to the projection parameter adjustment operation is the projection distance.

[0060] like Figure 4As shown, when it is determined that the projection parameter corresponding to the projection parameter adjustment operation is the projection distance, if it is determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation that one finger of the user long presses the second touch sub-area of ​​the touch area of ​​the touch frame, and another finger of the user moves to touch the second touch sub-area of ​​the touch area of ​​the touch frame, and the distance between the two fingers of the user increases, then the current projection distance of the projection unit is increased to obtain the target projection distance. Of course, it is not limited to this and is not limited here.

[0061] like Figure 5 As shown, when it is determined that the projection parameter corresponding to the projection parameter adjustment operation is the projection distance, if it is determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation that one finger of the user long presses the second touch sub-area of ​​the touch area of ​​the touch frame, and another finger of the user moves to touch the second touch sub-area of ​​the touch area of ​​the touch frame, and the distance between the two fingers of the user decreases, then the current projection distance of the projection unit is reduced to obtain the target projection distance. Of course, it is not limited to this and is not limited here.

[0062] In an exemplary embodiment, after determining that the projection parameter corresponding to the projection parameter adjustment operation is the projection distance according to the operation position information corresponding to the projection parameter adjustment operation, the operation position information corresponding to the projection parameter adjustment operation can be continuously obtained to determine whether the distance between the two fingers of the user increases or decreases; or it can be converted to obtain the hand posture information corresponding to the projection parameter adjustment operation to determine whether the distance between the two fingers of the user increases or decreases. Of course, it is not limited to this. For example, after determining that the projection parameter corresponding to the projection parameter adjustment operation is the projection distance according to the operation position information corresponding to the projection parameter adjustment operation, one of the user's fingers may leave the first touch sub-area when moving the first touch sub-area of ​​the touch area of ​​the touch frame. However, the distance between the two fingers of the user continues to increase or decrease. In this case, the operation position information corresponding to the projection parameter adjustment operation and the hand posture information can be combined to determine whether the distance between the two fingers of the user increases or decreases. This is not limited here.

[0063] In this way, when it is determined that the touch position of at least one finger of the user is in the first touch sub-area or the second touch sub-area of ​​the frame touch area according to the operation position information corresponding to the projection parameter adjustment operation, the projection parameter corresponding to the projection parameter adjustment operation is determined to be the projection size or the projection distance, which is conducive to improving the accuracy of determining the user's adjustment requirements for the projection parameters of the near-eye display device, thereby helping to improve the convenience and flexibility of adjusting the projection parameters of the near-eye display device.

[0064] In some embodiments, when it is determined according to the hand posture information corresponding to the projection parameter adjustment operation that the duration for which the user's first finger touches the touch area of ​​the frame is greater than or equal to a preset duration threshold, the projection parameter corresponding to the projection parameter adjustment operation is determined to be the projection size; when it is determined according to the hand posture information corresponding to the projection parameter adjustment operation that the user's second finger touches the touch area of ​​the frame is greater than or equal to the preset duration threshold, the projection parameter corresponding to the projection parameter adjustment operation is determined to be the projection distance.

[0065] For example, Figure 2 or Figure 3 As shown, taking the case where the user's first finger includes the user's thumb as an example, when it is determined according to the hand posture information corresponding to the projection parameter adjustment operation that the user's thumb continuously touches the frame touch area, and the duration of the user's thumb touching the frame touch area is greater than or equal to the preset duration threshold, the projection parameter corresponding to the projection parameter adjustment operation can be determined to be the projection size. Of course, it is not limited to this. Taking the case where the user's first finger includes the user's thumb, the user's second finger includes the user's index finger, and the hand posture information corresponding to the projection parameter adjustment operation includes but is not limited to the fingerprint information corresponding to the projection parameter adjustment operation as an example, when it is determined according to the hand posture information corresponding to the projection parameter adjustment operation that the user's thumb and the user's index finger both continuously touch the frame touch area, wherein the user's thumb continuously touches a certain position of the frame touch area, the user's index finger moves to touch multiple positions of the frame touch area, and the duration of the user's thumb touching a certain position of the frame touch area is greater than or equal to the preset duration threshold, the projection parameter corresponding to the projection parameter adjustment operation can be determined to be the projection size, which is not limited here.

[0066] like Figure 2 As shown, in the case where it is determined that the projection parameter corresponding to the projection parameter adjustment operation is the projection size, if it is determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation that the duration of the user's first finger touching the touch area of ​​the frame is greater than or equal to the preset duration threshold, and the distance between the user's first finger and the user's second finger increases, then the current projection size of the projection unit is increased to obtain the target projection size. For example, the user's first finger, such as the thumb, continuously touches a certain position on the right side of the touch area of ​​the frame, and the user's second finger, such as the index finger, gradually moves from the right side of the touch area of ​​the frame to the left, that is, the distance between the two fingers of the user increases, then the current projection size of the projection unit is increased to obtain the target projection size. Of course, it is not limited to this, and no limitation is made here.

[0067] like Figure 3As shown, in the case where it is determined that the projection parameter corresponding to the projection parameter adjustment operation is the projection size, if it is determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation that the duration of the user's first finger touching the touch area of ​​the frame is greater than or equal to the preset duration threshold, and the distance between the user's first finger and the user's second finger decreases, then the current projection size of the projection unit is reduced to obtain the target projection size. For example, the user's first finger, such as the thumb, continuously touches a certain position on the right side of the touch area of ​​the frame, and the user's second finger, such as the index finger, gradually moves from the left side of the touch area of ​​the frame to the right, that is, the distance between the two fingers of the user decreases, then the current projection size of the projection unit is reduced to obtain the target projection size. Of course, it is not limited to this, and no limitation is made here.

[0068] For example, Figure 4 and Figure 5 As shown, taking the user's second finger including the user's index finger as an example, when it is determined according to the hand posture information corresponding to the projection parameter adjustment operation that the user's index finger continuously touches the touch area of ​​the frame, and the duration of the user's index finger touching the touch area of ​​the frame is greater than or equal to the preset duration threshold, the projection parameter corresponding to the projection parameter adjustment operation can be determined to be the projection distance. Of course, it is not limited to this. For example, when it is determined according to the hand posture information corresponding to the projection parameter adjustment operation that the duration of the user's index finger touching a certain position of the touch area of ​​the frame is greater than or equal to the preset duration threshold, the projection parameter corresponding to the projection parameter adjustment operation can be determined to be the projection distance, which is not limited here.

[0069] like Figure 4 As shown, in the case where it is determined that the projection parameter corresponding to the projection parameter adjustment operation is the projection distance, if it is determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation that the duration of the user's second finger touching the touch area of ​​the frame is greater than or equal to the preset duration threshold, and the distance between the user's second finger and the user's first finger increases, then the current projection distance of the projection unit is increased to obtain the target projection distance. For example, the user's second finger, such as the index finger, continuously touches a certain position on the right side of the touch area of ​​the frame, and the user's first finger, such as the thumb, gradually moves from the right side of the touch area of ​​the frame to the left, that is, the distance between the two fingers of the user increases, then the current projection distance of the projection unit is increased to obtain the target projection distance. Of course, it is not limited to this, and no limitation is made here.

[0070] like Figure 5As shown, in the case where it is determined that the projection parameter corresponding to the projection parameter adjustment operation is the projection distance, if it is determined according to at least one of the operation position information and the hand posture information corresponding to the projection parameter adjustment operation that the duration of the user's second finger touching the touch area of ​​the frame is greater than or equal to the preset duration threshold, and the distance between the user's second finger and the user's first finger decreases, then the current projection distance of the projection unit is reduced to obtain the target projection distance. For example, the user's second finger, such as the index finger, continuously touches a certain position on the right side of the touch area of ​​the frame, and the user's first finger, such as the thumb, gradually moves from the left side of the touch area of ​​the frame to the right, that is, the distance between the two fingers of the user decreases, then the current projection distance of the projection unit is reduced to obtain the target projection distance. Of course, it is not limited to this, and no limitation is made here.

[0071] In this way, when it is determined according to the hand posture information corresponding to the projection parameter adjustment operation that the duration of the user's first finger or the user's second finger touching the touch area of ​​the frame is greater than or equal to the preset duration threshold, the projection parameter corresponding to the projection parameter adjustment operation is determined to be the projection size or the projection distance, which is conducive to improving the accuracy of determining the user's adjustment requirements for the projection parameters of the near-eye display device, thereby helping to improve the convenience and flexibility of adjusting the projection parameters of the near-eye display device.

[0072] In some embodiments, a projection parameter adjustment range corresponding to the near-eye display device is determined based on at least one of the scene in which the near-eye display device is located and the projection content of the near-eye display device; based on the projection parameter adjustment range corresponding to the near-eye display device, a target projection parameter of the projection unit is determined based on at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation.

[0073] For example, when a user projects corresponding projection content through a projection unit of a near-eye display device, the user has at least one of an anti-blocking requirement and a privacy protection requirement for the projection content of the projection unit. For example, in the process of projecting through the projection unit of a near-eye display device, the user needs to avoid other users blocking the projection content of the projection unit while browsing the projection content, or, in the process of projecting through the projection unit of a near-eye display device, the user needs to avoid other users browsing the projection content of the projection unit as much as possible while browsing the projection content. For another example, in the process of projecting through the projection unit of a near-eye display device, the user needs to avoid other users from knowing the user's privacy information while browsing user privacy information such as chat content, account password interface, and photos.

[0074] Based on this, the projection parameters of the projection unit can be set according to at least one of the scene in which the near-eye display device is located and the projection content of the near-eye display device. For example, the projection parameter adjustment range of the projection parameter adjustment of the projection parameter of the projection unit by the near-eye display device can be limited. For example, when the near-eye display device obtains the projection parameter adjustment operation, the projection parameters of the projection unit can be set in combination with the projection parameter adjustment range corresponding to the near-eye display device, so as to reduce the possibility of other users blocking the projection content or knowing the projection content during the process of the user projecting the projection content through the projection unit of the near-eye display device, thereby improving the user's projection experience of the near-eye display device and protecting the user's privacy.

[0075] In some embodiments, when the scene in which the near-eye display device is located includes at least one of an outdoor scene and a multi-person scene, the projection parameter adjustment range corresponding to the near-eye display device is determined to be a first projection parameter adjustment range; the first projection parameter adjustment range is smaller than the maximum projection parameter adjustment range corresponding to the near-eye display device.

[0076] For example, the scene in which the near-eye display device is located can be identified by at least one of the cameras and sensors provided on the near-eye display device, but this is not limited to this and is not limited here. When the scene in which the near-eye display device is located includes at least one of an outdoor scene and a multi-person scene, the possibility that the scene in which the near-eye display device is located includes other users other than the user using the near-eye display device is high, and the projection parameter adjustment range corresponding to the near-eye display device can be adjusted down, for example, the projection parameter adjustment range corresponding to the near-eye display device is determined to be a first projection parameter adjustment range, and the first projection parameter adjustment range is smaller than the maximum projection parameter adjustment range corresponding to the near-eye display device, such as one-half of the maximum projection parameter adjustment range, one-third of the maximum projection parameter adjustment range, and so on, which are not limited here. Based on the fact that the first projection parameter adjustment range is smaller than the maximum projection parameter adjustment range corresponding to the near-eye display device, when the projection content is projected through the projection unit of the near-eye display device, the possibility of other users blocking the projection content or the projection content is reduced, which is conducive to improving the user's projection experience of the near-eye display device and protecting the user's privacy.

[0077] In some embodiments, when the projection content of the near-eye display device includes user privacy information, the projection parameter adjustment range corresponding to the near-eye display device is determined to be a second projection parameter adjustment range; the second projection parameter adjustment range is smaller than the first projection parameter adjustment range.

[0078] For example, when the projection content of the near-eye display device includes user privacy content, the projection parameter adjustment range corresponding to the near-eye display device can be reduced, for example, the projection parameter adjustment range corresponding to the near-eye display device is determined to be the second projection parameter adjustment range, and the second projection parameter adjustment range is smaller than the first projection parameter adjustment range, such as two-thirds of the first projection parameter adjustment range, one-third of the first projection parameter adjustment range, and so on, which is not limited here. Based on the fact that the second projection parameter adjustment range is smaller than the first projection parameter adjustment range, when the projection content is projected through the projection unit of the near-eye display device, the possibility of other users blocking the projection content or knowing the projection content is further reduced, which is conducive to improving the user's projection experience of the near-eye display device and protecting user privacy.

[0079] S103: Control a projection unit of a near-eye display device to perform projection according to target projection parameters.

[0080] For example, when the target projection parameters are determined according to the projection parameter adjustment operation, the near-eye display device can control the projection unit to perform projection according to the determined target projection parameters, so that the projection parameters of the projection unit meet the projection requirements of the user for the near-eye display device. For example, in the process of the user performing the projection parameter adjustment operation on the near-eye display device, the process of the near-eye display device adjusting the projection parameters of the projection unit based on the projection parameter adjustment operation can be displayed, for example, the projection unit of the near-eye display device projects preset projection content, such as a solid color background image, an example image, etc., and in response to the projection parameter adjustment operation, the projection parameter change process is displayed, for example, the projection size changes from large to small, the projection size changes from small to large, the projection distance changes from far to near, and the projection distance changes from near to far, then the user can determine the target projection parameters according to the browsing experience of the preset projection content, so that the near-eye display device controls the projection unit according to the target projection parameters. Of course, it is not limited to this, and no limitation is made here.

[0081] In some embodiments, when a projection parameter adjustment operation is not obtained again within a preset time period after the projection parameter adjustment operation is obtained, the projection unit of the near-eye display device is controlled to perform projection according to the target projection parameters; and / or, when a user's confirmation operation is obtained, the projection unit of the near-eye display device is controlled to perform projection according to the target projection parameters.

[0082] For example, when a user performs a touch operation on the near-eye display device to adjust the projection parameters, if the user's finger stops touching the near-eye display device and the user's finger does not touch the near-eye display device again within a preset time, the near-eye display device does not obtain the projection parameter adjustment operation again within a preset time after obtaining the projection parameter adjustment, and can control the projection unit of the near-eye display device to perform projection according to the target projection parameters. Of course, this is not limited to this and is not limited here.

[0083] For example, when a user performs gesture interaction on a near-eye display device to adjust projection parameters, if the user performs a determination operation on the near-eye display device through a gesture, the near-eye display device obtains the user's determination operation and can control the projection unit of the near-eye display device to perform projection according to the target projection parameters. Of course, this is not limited to this and is not limited here.

[0084] In an exemplary embodiment, the user continuously touches the touch area of ​​the frame with a first finger, and moves the touch area of ​​the frame with a second finger to adjust the projection parameters of the near-eye display device. During the process of the user adjusting the projection parameters of the near-eye display device, if it is determined that the adjusted projection parameters are the projection parameters required by the user, the user can release the first finger and the second finger touching the touch area of ​​the frame to determine the target projection parameters, so that the near-eye display device can control the projection unit of the near-eye display device to perform projection according to the target projection parameters. Of course, this is not limited to this, and no limitation is made here.

[0085] In this way, by controlling the projection unit of the near-eye display device to perform projection according to the target projection parameters, it is helpful to improve the convenience of controlling the projection glasses to perform projection, and it is helpful to enhance the user's projection experience of the near-eye display device.

[0086] The control method of the near-eye display device provided in the above embodiment obtains the user's projection parameter adjustment operation when the projection unit of the near-eye display device is in a projection state; determines the target projection parameters of the projection unit according to at least one of the operation position information and hand posture information corresponding to the projection parameter adjustment operation; and controls the projection unit of the near-eye display device to perform projection according to the target projection parameters, so as to improve the convenience and flexibility of adjusting the projection parameters of the near-eye display device and enhance the user's projection experience of the near-eye display device.

[0105] Exemplarily, the near-eye display device includes a frame touch area. The first determination submodule includes a second size determination submodule and a second distance determination submodule.

[0106] The second size determination submodule is used to determine that the projection parameter corresponding to the projection parameter adjustment operation is the projection size when it is determined based on the hand posture information corresponding to the projection parameter adjustment operation that the duration of the user's first finger touching the touch area of ​​the frame is greater than or equal to a preset duration threshold.
