In this case, the method for displaying the view may be performed by the server 3, and accordingly, the means for displaying the view may be provided in the server 3.
Exemplary method
FIG. 2 is a flow diagram of a method for displaying views in one embodiment of the present disclosure. The embodiment can be applied to a dual-screen stereoscopic display device, such as an AR head-mounted display device, a VR head-mounted display device, and the like, as shown in fig. 1. In this embodiment, as shown in fig. 2, the method for displaying a view may include the steps of:
s2: in response to receiving the view scrolling instruction, a view scrolling direction and a scrolling distance in a target interface displayed by the head mounted display device are determined.
The view scrolling instructions may be sent to the head mounted display device by a controller of the head mounted display device. The view scrolling instruction is used for controlling the view in the target interface displayed by the head-mounted display device to scroll. The controller may be a real controller that communicates with the head-mounted display device, for example, a control terminal such as a mobile phone. The controller may also be a virtual controller, for example, generated within a virtual area displayed by the head mounted display device.
The controller may render a target interface in which multiple views are currently displayed, for example, multiple views are displayed on the target interface in a row and column arrangement. FIG. 3 is a schematic illustration of a target interface at a first time in one example of the disclosure. As shown in FIG. 3, in the present example, the target interface displays 8 views at the first moment, and the 8 views are arranged in rows and columns to be displayed in 2 rows and 4 columns. Wherein, the x direction is the horizontal direction of the target interface, and the y direction is the vertical direction of the target interface.
And after receiving the view scrolling instruction, acquiring a view scrolling direction and a scrolling distance in a target interface displayed by the head-mounted display device through the view scrolling instruction. Wherein the view scrolling direction may be one of view scrolling up, view scrolling down, view scrolling left, and view scrolling right. Taking fig. 3 as an example, the view scrolling command may control the view in the target interface to scroll in the y-axis positive semi-axis direction, the y-axis negative semi-axis direction, the x-axis positive semi-axis direction, or the x-axis negative semi-axis direction. The scroll distance may be determined according to a distance indicated by the scroll command.
In general, the view scrolling instructions described above may be generated in a variety of ways. For example, the user generates a view scrolling instruction by sliding the target interface upwards, in this case, the view scrolling direction indicated by the view scrolling instruction may be the direction upwards along the target interface, and the view scrolling distance may be determined according to the distance the user slides on the target interface.
S4: and controlling the first view and a first mask corresponding to the first view to scroll based on the view scrolling direction and the scrolling distance. The target interface comprises at least one first view, a first mask covers partial area of the first view, the size of the first mask is smaller than that of the first view, and the scrolling speed of the first mask is larger than that of the first view.
The size of the first mask can be a size corresponding to the hollow part of the first mask frame, and the size is smaller than that of the first view, so that the part of the first view can be displayed through the first mask. It will be appreciated that the controller may render a first mask and a corresponding first view at different display depths, respectively, wherein the first mask is closer to the head mounted display device than the first view. The scrolling speed of the first mask is greater than that of the first view, and the content of the first view displayed through the first mask in the rendered image can be dynamically changed in the process of scrolling the first view and the first mask, so that a dynamic three-dimensional depth effect is generated.
It is to be understood that the device for displaying views of the present application may be a dual-screen stereoscopic display device, such as an AR head-mounted display device, a VR head-mounted display device, or the like. Therefore, the controller can render different objects at different display depths to perform stereoscopic display. For example, the controller may render the first view and the corresponding first mask at different display depths. Fig. 4 is a side view schematic diagram of a wearable device in use at a first time in one example of the present disclosure. As shown in fig. 3 and 4, the first view may include at least view 8. The first mask may comprise at least a mask 8 corresponding to the view 8, and the mask 8 is an outer frame mask. The z-axis direction is a display depth direction of the head-mounted display device, a dotted line direction between the mask 8 and the view 8 is parallel to the z-axis direction, and the depth of the mask 8 is smaller than that of the view 8.
In one example of the present disclosure, the background control may be used to control the view 8 for scrolling and the mask control may be used to control the mask 8 for scrolling. The manner of using the background control to control the view 8 to scroll may include: the background control acquires view rendering data of the view 8, which may include a rendering position, a rendering size and a rendering content of the view 8; the background control is used to control the view 8 to scroll the scroll distance in the view scroll direction. The manner in which the mask 8 is controlled to scroll using the mask control may include: the mask control acquires rendering data of the mask 8, including the rendering position, the rendering size and the rendering content of the mask 8; the mask control mask 8 is used to scroll the scroll distance in the view scroll direction.
At a first moment, due to the occlusion of the mask 8, the user can only see a partial area of the view 8 when viewing the view 8 using the head mounted display device. The partial area includes the area a of fig. 8.
Upon receiving the view scroll instruction, the background control and the mask control may be used to control the view 8 and the mask 8, respectively, to scroll. Since the size of the mask 8 is smaller than the size of the view 8 and the scrolling speed of the mask 8 is greater than the scrolling speed of the view 8, when the view 8 and the mask 8 are scrolled, the content of the view 8 can be seen through the mask 8, and can be updated along with the scrolling direction of the view, so that a strong three-dimensional stereoscopic impression can be provided for a user using the head-mounted display device.
Fig. 5 is a side view schematic of a wearable device in use at a second moment in one example of the disclosure. The second time may be a certain time after the view 8 scrolls according to the view scroll instruction. As shown in fig. 5, after the view 8 is scrolled, the position of the area a of the view 8 in the hollow area of the mask 8 is obviously changed due to the difference between the scrolling speeds of the view 8 and the mask 8.
S6: responsive to the first view scrolling away from the view display area of the target interface, the scroll processing resources of the first view are released.
During the process that the first view is scrolled according to the view scrolling direction and the scrolling distance in the view scrolling instruction, if the first view does not complete the scrolling distance in the view scrolling instruction, the first view leaves the view display area of the target interface, for example, the view scrolling direction is a first preset direction, the scrolling distance is L1, the distance between the first view and the boundary of the view display area of the target interface in the first preset scrolling direction is L2, and L1> L2. When the first view has scrolled a distance of L2, the distance of incomplete scrolling being L1, at which point the first view has left the view display area of the target interface, then the scroll processing resources of the first view are released, thereby avoiding the view away from the user's visual area from using the scroll processing resources to cause a system jam.
The scroll processing resource may include a control that controls the first view to scroll, for example, when the view 8 leaves the view display area of the target interface, a background control that controls the view 8 to scroll may be released, and a mask control that may release the mask 8 to scroll may also be released.
In this embodiment, after receiving the view scroll instruction, the first view and the first mask in the control target interface are scrolled. In the rolling process, the first view is shielded through the first shade, so that the visual area of the first view is continuously changed by the head-mounted display device, the changing feeling of the display internal movement can be brought to the depth of a user using the head-mounted display device, and the visual three-dimensional stereoscopic impression is improved. And when the first view leaves the view display area of the target interface, releasing the scroll processing resource of the first view, thereby reducing the probability of image stagnation caused by the scroll processing resource used by the view leaving the visual area of the user.
In an optional embodiment of the present disclosure, before step S2, the method may further include:
s0: a background control and a mask control are generated based on rendering data of the first view. The background control may control the first view to scroll, for example, the background control acquires view size information of the first view, the number of pixels included in the first view, and a pixel value of each pixel, and when the first view needs to be controlled to scroll, all pixels included in the first view may be controlled to move synchronously through the background control. The mask control may control the first mask to scroll, for example, the mask control obtains size information of the first mask, the number of pixels included in the first mask, and a pixel value of each pixel, and when the first mask needs to be controlled to scroll, the mask control may control all pixels included in the first mask to move synchronously.
In this embodiment, the background control and the mask control may be generated before the first view is scrolled, and the scroll control is high in accuracy by controlling the first view and the first mask to scroll through the background control and the mask control. It will be appreciated that the background control and corresponding mask control may also be generated based on the first view upon receiving a view scrolling instruction, without limitation.
In an optional embodiment of the present disclosure, after step S6, the method may further include:
s8: the scroll processing resource of the first view is multiplexed with the current view in the target interface. Wherein the scroll processing resource of the first view may include a control that controls the first view and the first mask to scroll.
In this embodiment, after the first view leaves the current display area of the target interface, the control controlling the first view and the first mask to scroll may be released, and the released control is multiplexed onto the newly appearing view in the target interface to control the newly appearing view to scroll.
In one embodiment of the present disclosure, the view scrolling direction includes a first preset direction, for example, the first preset direction may be a view scrolling up direction. The method for displaying a view may further include:
and SA-2: in response to receiving the view scrolling instruction, a second view and a second mask corresponding to the second view are rendered. The distance between the second view and the target interface in the depth direction is a preset distance, the second mask covers a partial area of the second view, and the size of the second mask can be smaller than that of the second view.
The target interface and the views in the target interface may be rendered prior to receiving the view scrolling instructions.
Upon receiving the view scrolling instruction, the second view may be rendered according to the view rendering data of the second view and the second mask may be rendered according to the rendering data of the second mask, where the display depth of the second view may be greater than the depth of the first view. That is, in the display depth direction, the first view is closer to the head mounted display device. It should be further noted that the second view and the second mask corresponding to the second view are at least partially occluded at the target interface.
It can be understood that, when the controller renders the second image, the controller sets the second mask corresponding to the second image, so that the second image only displays the content corresponding to the second mask hollow area, and the display area and the display content amount are controllable.
SA-4: and when the first view is scrolled along a first preset direction, controlling the second view and the second mask to move towards the direction close to the target interface so that the distance between the second image and the target interface in the depth direction is gradually reduced.
Fig. 6 is a side view schematic of a wearable device in use at a third time in one example of the present disclosure. Wherein the third time may be between the first time and the second time. As shown in fig. 3 and 6, in one example of the present disclosure, the second view may include a view 12, and when the first view is scrolled in a first preset direction, the view 12 is moved to a direction close to the target interface.
SA-6: and controlling the second view and the second mask to move along the first preset direction under the condition that the preset point of the first view is scrolled to the first critical line. The first critical line is a critical line of the target interface in a first preset direction, and the moving speed of the second mask in the first preset direction is greater than that of the second view in the first preset direction.
In an example of the present disclosure, the preset point of the first view may be a preset point of the first view in a first preset direction, for example, when the first preset direction is a view upward scrolling direction, the preset point of the first view may be one of pixel points between a first row of pixel points in a downward-upward direction of the first view. It is preset that when the preset point of the first view reaches the first critical line, the second view just reaches the target interface, and the second view stops moving in the direction of decreasing depth. FIG. 7 is a schematic illustration of the direction of movement of view 12 after entering the target interface in the example shown in FIG. 6 of the present disclosure. When the preset point of view 8 is scrolled to the first critical line as shown in fig. 7, the view 12 just reaches the target interface, and the depth of the view 12 may be the same as the display depth of the target interface. The view 12 may then continue to be controlled to move upward in accordance with the view scrolling instructions.
In this embodiment, when the view scrolling instruction is received, the second view and the second mask may be rendered, so that compared with a method of rendering the second view and the second mask in advance, the resource consumption of the system may be reduced, and the display stuck probability may be reduced. And the first view and the second view are respectively rendered at different display depths, and when the first view moves to a first preset direction, the second view is controlled to move to a direction close to the target interface, so that the change of the relative position of the views on the spatial depth can be embodied, and the three-dimensional visual perception is further enhanced. When the preset point of the first view is scrolled to the first critical line, the second view and the second mask can be controlled to move towards the first preset direction, the second view is shielded through the second mask, and the moving speed difference between the second mask and the second view enables the visual area of the second view to be continuously changed through the head-mounted display device, the depth change feeling can be brought to a user using the head-mounted display device, and the three-dimensional stereoscopic impression is improved.
In an embodiment of the present disclosure, in the process of controlling the second view to move to a direction close to the target interface, the method further includes: and controlling the transparency parameter of the second view to be increased as the distance between the second view and the target interface is reduced, so that the transparency of the second view is gradually increased. Wherein the greater the transparency of the second view, the clearer the second view; the smaller the transparency of the second view, the more blurred the second view.
In this embodiment, in the moving process of the second view to the direction close to the target interface, the transparency of the second view is controlled to be gradually increased, so that when a distant view gradually approaches the user, the view gradually becomes clear, and the three-dimensional display effect can be improved.
In one embodiment of the present disclosure, the view scrolling direction includes a second preset direction, for example, the second preset direction may be a view downward scrolling direction. The method for displaying a view may further include:
SC: and after the preset point of the first view is scrolled to the second critical line, controlling the first view to move in the direction away from the target interface so that the distance between the first image and the target interface in the depth direction is gradually increased. And the second critical line is a critical line of the target interface in a second preset direction.
In an example of the present disclosure, the preset point of the first view may be a preset point of the first view in a second preset direction, for example, when the first preset direction is a view-down scrolling direction, the preset point of the first view may be one of the first row of pixel points in a top-down direction of the first view. And when the preset point of the first view reaches a preset second critical line, the first view starts to move in a direction away from the target interface and the depth of the first view increases.
In this embodiment, after the preset point of the first view is scrolled to the second critical line, the first view is controlled to move towards the direction away from the target interface, so as to provide the user with a visual feeling that the first view gradually gets away from the user, and further improve the three-dimensional display effect.
In an embodiment of the present disclosure, during the moving of the first view away from the target interface, the method further includes: the transparency parameter controlling the first view decreases as the distance between the first view and the target interface increases. Wherein the greater the transparency of the first view, the clearer the first view; the smaller the transparency of the first view, the more blurred the first view.
In this embodiment, in the process of moving the first view away from the target interface, the transparency of the first view is controlled to be gradually reduced, so that when a near view of the user is gradually away from the user, the view is gradually blurred, and the three-dimensional display effect can be further improved.
Fig. 8 is a schematic flow chart of step SC in an embodiment of the present disclosure. As shown in fig. 8, step SC may include:
SC-2: and acquiring a distance difference value between the rolling distance and the preset point moving distance. And the preset point moving distance is the distance between the initial position of the preset point of the first view and the second critical line.
The initial position of the preset point of the first view is the position of the preset point of the first view in the target interface before the scrolling is performed according to the view scrolling instruction. In one example of the present disclosure, the scroll distance corresponding to the view scroll instruction is L1, the distance between the initial position of the preset point of the first view and the second critical line position is L2, and L1> L2. The difference in distance between the scrolling distance and the preset point movement distance is L3, where L3 is L1-L2.
SC-4: and determining the moving distance of the first view in the direction away from the target interface based on the distance difference and the moving distance conversion relation. The moving distance conversion relation is a distance conversion relation between the moving distance in the second preset direction and the moving distance in the direction far away from the target interface.
In one embodiment of the present disclosure, the moving distance transformation relationship is 1: and K, namely after the preset point of the first view is scrolled to the second critical line, the first view originally continues to move 1 unit distance in the second preset direction, and the first view is transformed to move K unit distances in the direction away from the target interface. Assuming that the moving distance of the first view in the direction away from the target interface is L4, L4 is K × L3.
In this embodiment, when the first view is controlled to scroll in the second preset direction according to the view scrolling instruction, if the critical point of the first view has not executed the scrolling distance corresponding to the view scrolling instruction when scrolling to the second critical line, the moving direction of the first view is changed, and the first view is controlled to move in the direction away from the target interface.
In an optional embodiment of the present disclosure, step S8 may further include:
when the preset point of the first view is scrolled to the second critical line, the first distance value is acquired. The first distance value is a distance value between an initial position of the preset point of the first view and the second critical line, and the initial position of the preset point of the first view is a position of the preset point of the first view before scrolling according to the view scrolling instruction.
Based on the scroll distance and the first distance value, a second distance value is determined. The distance value obtained by subtracting the first distance value from the distance value corresponding to the scroll distance may be used as the second distance value.
Based on the second distance value, a distance of movement of the first view in a direction away from the target interface is controlled. For example, after the preset point of the first view is scrolled to the second critical line, the preset point is moved by the second distance value in a direction away from the target interface.
In this embodiment, when the first view is controlled to scroll in the second preset direction according to the view scrolling instruction, if the critical point of the first view has not executed the scrolling distance corresponding to the view scrolling instruction when the first view is scrolled to the second critical line, the original moving direction of the first view is changed to continue moving, and by changing the view moving direction, the first view can move not only in the second preset direction at the same display depth, but also in different display depths, so that the three-dimensional visual effect can be enhanced.
In one embodiment of the present disclosure, step SA-6 includes: and under the condition that the preset point of the first view is scrolled to the first critical line, the second view moves to the target interface, and the second view is determined as the first view and then moves along the first preset direction. In this embodiment, after the second view is moved to the target interface, the second view may be determined as the first view in the target interface. After receiving the view scrolling instruction, the method provided by the embodiments may be executed to control the first view to move along the view scrolling direction. It is understood that the controller may render a new second view and a corresponding second mask while the scrolling direction is in the first predetermined direction.
In this embodiment, when the preset point of the first view is scrolled to the first critical line, the second view is just moved to the target interface, and thereafter the second view may be determined as the first view and moved along the first preset direction.
