[0002] With the rapid development of computer technology, people can now use powerful terminal devices to perform various types of virtual interactions. These virtual interactions can simulate various phenomena in the real world.

[0003] Maps are widely used in various virtual interactive scenarios such as games and simulations. For example, when a map in a virtual environment serves as a game platform, players can control virtual objects to find targets within the map, often requiring them to move the map to locate these targets. However, current map movement controls are cumbersome and do not allow for quick target finding. Summary of the Invention

[0018] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0019] In the description of embodiments of this disclosure, the term "comprising" and similar terms should be understood as open-ended inclusion, i.e., "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions may also be included below. The terms "first", "second", etc., may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0020] As briefly mentioned earlier, the map in the virtual environment plays a crucial role as the game's medium. Players need to continuously swipe on the map to find targets (e.g., mines, oil fields) and perform actions on them (e.g., gathering resources, combat). In the first method of finding targets on the map, players use a "search" function key. They enter the target's name in the corresponding input box, click the key, and the map automatically jumps to the target's coordinates, allowing for direct action. However, this method lacks a strong sense of the target's location on the map, diminishing the fun of searching for targets. The second method involves switching between a large and small map. However, this switching is cumbersome, and the mapping relationship is unclear, making it difficult for players to quickly find targets. In the third method, players can switch targets by swiping the viewfinder. Since the viewfinder size changes with the player's map zoom, the swiping action is sensitive, making it difficult for players to control the viewfinder's position, further hindering quick target finding.

[0021] This disclosure proposes a scheme for viewpoint control in a virtual environment. According to various embodiments of this disclosure, firstly, a map interface presents first scene information of a virtual scene (e.g., a game scene) from an initial viewpoint. In response to a preset operation performed on the map interface (e.g., long-pressing a location on the map interface), a movement control associated with the map interface is presented on the map interface. Further, based on interactions with the movement control (e.g., a user controlling a sliding movement control on the map interface), changes in the viewpoint of the virtual scene can be determined, and based on the initial viewpoint and the viewpoint changes, the changed viewpoint is obtained, and second scene information is presented on the map interface from the changed viewpoint.

[0022] Therefore, in the embodiments of this disclosure, by interacting with the mobile controls presented on the map interface, the perspective of the virtual scene changes, and the scene information is presented on the map interface from the changed perspective, thereby enabling the player to find the target within the scene information presented from the changed perspective. Since interacting with the mobile controls can change the perspective of the virtual scene, that is, change the map scene displayed on the map interface, players can quickly and accurately find the target on the map interface.

[0023] The following detailed description of various example implementations of this solution, in conjunction with the accompanying drawings, is provided. To illustrate the principles and ideas of the embodiments of this disclosure, some descriptions below will refer to the gaming industry. However, it will be understood that this is merely exemplary and is not intended to limit the scope of this disclosure in any way. Embodiments of this disclosure can be applied to various fields such as simulation, modeling, virtual reality, and augmented reality.

[0024] Example Environment

[0025] First see Figure 1 The illustration schematically shows a sample environment 100 in which exemplary implementations according to this disclosure may be implemented. Figure 1 As shown, example environment 100 may include electronic device 110.

[0026] In some embodiments, such as Figure 1 As shown, electronic device 110 may include, for example, a suitable type of portable device that can be held by the user's hands for various interactive operations. Such electronic device 110 may include, but is not limited to, smartphones, tablets, PDAs, portable gaming terminals, virtual reality or augmented reality devices, etc.

[0027] It should be understood that, although electronic device 110 is in Figure 1The device is shown as a portable device, but this is only illustrative. In some other embodiments, the electronic device 110 may also be other suitable forms. For example, the electronic device 110 may include a display device for display and a computing device for computation, and the display device and computing device may be physically coupled or decoupled, for example. For example, the electronic device 110 may include a display screen for image display and a game console for image rendering and game control.

[0028] Alternatively, electronic device 110 can achieve interaction using other suitable input devices, such as a keyboard, mouse, joystick, game controller, or other suitable interactive devices that are communicatively coupled.

[0029] Alternatively, the electronic device 110 can also achieve interaction via touch. For example, the electronic device 110 can achieve interaction through haptic feedback systems such as resistive technology, capacitive technology, infrared technology, and surface acoustic wave (SAW).

[0030] Continue to refer to Figure 1 The electronic device 110 may, for example, present an application interface 120, which may present a corresponding virtual environment. Such a virtual environment may include, but is not limited to, various types of game environments, simulation environments, or emulation environments. For example, the application interface 120 may be a game application interface to present a corresponding game-related virtual environment. Alternatively, the application interface 120 may also be other suitable types of interactive interfaces that can support user control of the movement of virtual objects in the interface.

[0031] In some embodiments, the electronic device 110 may present, in response to an interactive operation on the application interface 120, such as Figure 1 The map interface 121 shown is used to present scene information of the virtual environment of the map from the player's perspective. For example, the scene information presented by the map interface 121 can be the entire scene or at least a part of the scene of the virtual environment of the entire map. For example, the scene information can include virtual elements such as mountains, rivers, buildings, minerals, oil, animals and plants that the player needs to pass through in the process of finding a target on the map.

[0032] For example, such as Figure 1 As shown, the electronic device 110 can also display a game task interface 122, for example. The game task interface 122 can display, for example, the game task the player needs to complete, "Assemble at the base," and the completion status of operations performed on the target (e.g., gathering). For example, while on the way to the base, the player must perform gathering operations on multiple virtual elements and complete all gathering before reaching the destination base.

[0033] It is understood that other interfaces presented by the electronic device 110 may be interfaces displayed by the player during the game, and this embodiment does not make any specific limitations.

[0034] The following section will detail the specific process of viewpoint control in a virtual environment.

[0035] Example process

[0036] Figure 2 A flowchart of a process 200 for viewpoint control in a virtual environment according to some embodiments of the present disclosure is shown. Exemplarily, process 200 may be... Figure 1 The electronic device 110 can be implemented independently or in combination with other computing devices.

[0037] like Figure 2 As shown in box 210, the electronic device 110 presents the first scene information of the virtual environment from the initial perspective in the map interface.

[0038] In some embodiments, the viewpoint can be understood as the range of angles that a player can observe in a virtual environment. The initial viewpoint can be understood as the viewpoint corresponding to the moment the player enters the virtual environment. This moment can be determined as the player progresses during the game, and is not specifically limited in this embodiment.

[0039] For example, Figure 1 The scene information of the virtual environment presented in the initial viewpoint of the map interface 121 shown may include virtual elements such as bases and mountains (and many other virtual elements not shown in the figure). For ease of description, the scene information of the virtual environment presented in the initial viewpoint is also referred to herein as the first scene information.

[0040] In box 220, electronic device 110 responds to a preset operation for the map interface by presenting a motion control associated with the map interface.

[0041] Figure 3A A schematic diagram 300A is shown illustrating a motion control presented at a first interactive position in a map interface according to some embodiments of the present disclosure. Figure 3B A schematic diagram 300B is shown illustrating a motion control displayed at a preset location in a map interface according to some embodiments of the present disclosure. The following is in conjunction with... Figure 3A and Figure 3B This describes the process of rendering the mobile controls.

[0042] In some embodiments, the electronic device 110 may receive preset operations for the map interface 121. Alternatively, the electronic device 110 may receive preset operations for the map interface 121 via a touchscreen. For example, the electronic device 110 may receive pressure from a user's finger or other touch device (e.g., a stylus) on a corresponding area of ​​the map interface 121. Alternatively, the electronic device 110 may receive preset operations for the map interface 121 via a communication-coupled input device. For example, the electronic device 110 may receive input from a user via an input device (such as a mouse, keyboard, joystick, or game controller). For example, a user may use a mouse to press on an area of ​​the map interface 121.

[0043] For example, the preset operations that the electronic device 110 can receive may include preset operations performed on preset locations or any locations on the map interface 121. For instance, preset operations may be performed at the top, bottom, left, right, or center of the map interface 121. Preset operations may include long press, double-click, or other similar operations. For example, when presetting a long press operation on the map interface 121, the long press duration may be preset to 5 seconds or 10 seconds, etc. It is understood that preset operations can also be other types of gesture operations, and this embodiment does not impose specific limitations.

[0044] In some embodiments, the electronic device 110, in response to a preset operation on the map interface, determines the display position of the motion control on the map interface. This display position may include a first interactive position indicated by the preset operation, or a preset position. The electronic device 110 then presents the motion control at the display position.

[0045] like Figure 3A As shown, please refer to the first scene information of the virtual environment presented from the initial perspective in map interface 121. Figure 1 This will not be described in detail here. After receiving a preset operation for the map interface 121, the electronic device 110 can display the movement control 130 at a display location (e.g., location A) in the map interface 121.

[0046] In some embodiments, the location indicated by the preset operation of the map interface 121, which allows the user and the electronic device 110 to interact, is called the interaction location, and for convenience, it is also referred to as the first interaction location herein. The electronic device 110 can display the motion control 130 at the first interaction location. The display location is the first interaction location; that is, the display location is the same location as the first interaction location indicated by the preset operation. Figure 3A For example, the map interface 121 is subjected to preset operations such as long press and double tap by the gesture 140. The contact point of the gesture 140 on the map interface 121 (e.g., position A) is the first interaction position. The electronic device 110 can present the motion control 130 at position A.

[0047] In some embodiments, the electronic device 110 may display the motion control 130 at a preset location. For example, the preset location could be any location on the map interface 121. Figure 3B For example, the preset location could be location C in the lower right corner of the map interface 121. For instance, after the map interface 121 is subjected to a preset operation such as a long press or double-click by gesture 140, the first interaction location is determined to be location B, and the electronic device 110 displays the movement control 130 at the preset location C. It is understood that the displayed location (preset location, location C) and the first interaction location indicated by the preset operation (location B) may not be the same location.

[0048] In some embodiments, the electronic device 110 presents the motion control 130 in a semi-transparent manner overlaid on the map interface 121. For example, the semi-transparent shape of the motion control 130 can be freely set, such as any shape like a circle, rectangle, or irregular shape, and its area can be preset according to the ratio to the map interface 121; no specific limitation is made in this embodiment. The semi-transparent motion control 130 does not obstruct the map interface 121, which is beneficial for players to find targets on the map interface 121.

[0049] In some embodiments, the motion control 130 also indicates at least some of the virtual elements included in the scene associated with the first scene information. For ease of description, the scene associated with the first scene information is also referred to as the first scene herein. For example, the first scene may be larger or smaller than the scene presented in the map interface 121. The virtual elements included in the first scene may be virtual elements in the first scene that are presented in the map interface 121, or they may be virtual elements in the first scene that are not presented in the map interface 121.

[0050] For example, the first scene can be presented as a thumbnail of a semi-transparent map. The center of the thumbnail is associated with the center of the map interface 121, and the scene range displayed by the thumbnail can be a range extending outward from the center of the map interface 121 with a fixed radius (e.g., the thumbnail may include a fixed number of map areas of a predetermined size). In some embodiments, the elements presented in the thumbnail can change as the player zooms in and out of the virtual environment scene presented in the map interface 121.

[0051] In some embodiments, at least some virtual elements included in the first scene associated with the first scene information, such as key buildings, minerals, coordinates, etc., can be displayed in shapes such as squares, circles, or ellipses. Taking Figure 300A as an example, it may include display frames 150-1, 150-2, 150-3, etc., which are collectively referred to or individually as display frame 150. For example, display frame 150 can also be presented in a semi-transparent manner overlaid on a thumbnail of a semi-transparent map. For example, display frame 150-1 corresponds to presenting the virtual element base, and display frame 150-2 corresponds to presenting the virtual element mountain. If the electronic device 110 is selected (e.g., clicked) in the display frame 150 of the virtual element, the corresponding virtual element is enlarged and presented at an appropriate position on the map interface 121.

[0052] It should be noted that the parts of the first scene not shown in the map interface 121, as well as the virtual elements not shown, can be shown in the map interface 121 by changing the viewpoint.

[0053] Continue to refer to Figure 2 In box 230, electronic device 110 can determine the change of viewpoint based on the interaction of the motion control.

[0054] Figure 4A A schematic diagram 400A shows a map interface before a change of view caused by interaction based on a mobile control according to some embodiments of the present disclosure. Figure 4B A schematic diagram 400B shows a map interface after a change in viewpoint caused by interaction based on a mobile control according to some embodiments of the present disclosure. The following is in conjunction with... Figure 4A and Figure 4B This describes the process of determining perspective changes based on the interaction of mobile controls.

[0055] In some embodiments, the motion control 130 may be a joystick control, and the interaction of the motion control 130 may be, for example, a swipe interaction on the joystick control. Exemplarily, the electronic device 110 may also implement a swipe interaction on the joystick control via touch.

[0056] In some embodiments, the electronic device 110 may determine a change in viewing angle based on an interaction with a motion control (e.g., a swipe interaction with a joystick control). In some embodiments, after an interaction with the motion control 130, the electronic device 110 may determine a second interaction position associated with the interaction with the motion control 130, and determine a change in viewing angle based on the second interaction position.

[0057] For example, electronic device 110 can receive a swipe interaction operation on mobile control 130. The starting position of the swipe interaction operation can be the center position of mobile control 130, or it can be any position on mobile control 130 other than the center position. The position of the swipe interaction operation on mobile control 130 is the ending position. For ease of description, the ending position of the operation corresponding to the interaction of mobile control 130 is referred to as the second interaction position in this document.

[0058] As shown in Figure 400A, the center position of the movement control 130 is position A. The sliding interaction operation starts from position A. Before sliding, the map interface 121 still presents the first scene information from the initial perspective, such as the base and mountains (and other virtual elements not shown in the figure). For example, the sliding interaction operation starts from position A and can slide in any direction. After sliding, the perspective changes, and based on the initial perspective and the change in perspective, the second scene information of the virtual environment is presented in the map interface 121, which will be described in detail below.

[0059] In some embodiments, the electronic device 110 may determine the direction of the viewpoint change based on a first angle between the second interactive position and the center position of the motion control; and determine the scale (or size) of the viewpoint change based on a first distance between the second interactive position and the center position of the motion control.

[0060] For example, as shown in Figure 400B, the starting position of the interaction is the center position A of the movement control, and the ending position of the interaction is position A', which is also the second interaction position. The electronic device 110 can determine the direction of the viewpoint change based on the angle between the line connecting positions A and A' and the horizontal line. For ease of description, this angle is referred to as the first angle. The electronic device 110 can determine the scale of the viewpoint change based on the distance between the second interaction position A' and the center position A of the movement control. For ease of description, this distance is referred to as the first distance. It can be understood that after interacting with the movement control 130, the electronic device 110 determines the direction and scale of the viewpoint change, and transforms the initial viewpoint based on the direction and scale of the viewpoint change. That is, the center of the map interface 121 is moved along the direction and scale of the viewpoint change in the map, resulting in the scene presented in the map interface 121 after the viewpoint change.

[0061] Alternatively or additionally, the electronic device 110 determines the scale of the viewpoint change from a preset set of scales based on a comparison between a first distance and a threshold distance. For example, if the first distance is greater than the threshold distance, a scale greater than the threshold scale is selected from the preset set of scales as the scale of the viewpoint change. If the first distance is less than the threshold distance, a scale less than the threshold scale is selected from the preset set of scales as the scale of the viewpoint change.

[0062] For example, the scale of the viewpoint change can correspond to the speed at which the map moves in the map interface based on the operation of the motion control 130. In some embodiments, the electronic device 110 can set one or more threshold distances. As an example, the threshold distance can include half the radius of the circular joystick control. Accordingly, when the first distance is greater than half the radius, the viewpoint change can correspond to a first scale, causing the map to move at a first speed. Conversely, when the first distance is less than or equal to half the radius, the viewpoint change can correspond to a second scale, causing the map to move at a second speed less than the first speed.

[0063] In some embodiments, the electronic device 110 may also be configured with multiple threshold distances. For example, the electronic device 110 may set one-third of the radius as a first threshold distance and two-thirds of the radius as a second threshold distance. In this case, if the first distance is less than one-third of the radius, the viewpoint change may correspond to a smaller scale, for example, causing the map to move at a slower speed; if the first distance is greater than or equal to one-third of the radius and less than two-thirds of the radius, the viewpoint change may correspond to a medium scale, for example, causing the map to move at a moderate speed; if the first distance is greater than or equal to two-thirds of the radius, the viewpoint change may correspond to a larger scale, for example, causing the map to move at a faster speed.

[0064] Based on the methods discussed above, the embodiments of this disclosure can achieve more flexible viewpoint control.

[0065] Alternatively or additionally, the electronic device 110 determines the scale of the viewpoint change such that the scale is proportional to the first distance. For example, as the first distance increases, the scale of the viewpoint change increases, or as the first distance decreases, the scale of the viewpoint change decreases.

[0066] In some embodiments, the electronic device 110 may determine the direction of the viewpoint change based on a second angle between the second interaction position and the starting position of the interaction; and determine the scale of the viewpoint change based on a second distance between the second interaction position and the starting position of the interaction.

[0067] For example, the starting position of the interaction can be any position other than the center position of the movement control (not shown in the figure), and the ending position of the interaction can be a second interaction position (not shown in the figure). The electronic device 110 can determine the direction of the viewpoint change based on the angle between the line connecting the starting and second interaction positions and the horizontal line. For ease of description, this angle is referred to as the second angle. The electronic device 110 can determine the scale of the viewpoint change based on the distance between the second interaction position and the starting position of the interaction. For ease of description, this distance is referred to as the second distance. It can be understood that after interacting with the movement control 130, the electronic device 110 similarly determines the direction and scale of the viewpoint change, and transforms the initial viewpoint based on the direction and scale of the viewpoint change. That is, the center of the map interface 121 is moved along the direction and scale of the viewpoint change within the map, so that the map interface 121 displays the scene after the viewpoint change.

[0068] Continue to refer to Figure 2 In box 240, electronic device 110 presents the second scene information of the virtual environment in the map interface based on the initial viewpoint and viewpoint changes.

[0069] In some embodiments, after the electronic device 110 transforms the initial viewpoint according to the direction and scale of the viewpoint change, the map interface 121 presents scene information of the virtual environment from the changed viewpoint. For ease of description, this is also referred to as second scene information. For example, as shown in Figure 400A, the map interface 121 presents the mountain (within the dashed box) from the initial viewpoint. Based on the initial viewpoint and the viewpoint change, as shown in Figure 400B, the map interface 121 presents the mountain (within the dashed box) from the changed viewpoint, while the base is removed from the map interface 121.

[0070] In some embodiments, the virtual environment scene presented in the map interface 121 after the electronic device 110 changes its viewing angle according to a first distance and a first angle is the same as the scene presented in the map interface 121 after the electronic device 110 changes its viewing angle according to a second distance and a second angle.

[0071] Based on the process described above, when players enter the game's map to search for virtual elements that can be collected, they perceive the positional relationships or distribution of these virtual elements through changes in perspective. The embodiments of this disclosure can achieve perspective changes through interactive movement controls, and present the scene before and after the perspective change on the map interface. This allows for fast and precise movement within the map, with controllable movement speed. Targets can be found more intuitively on the map interface without needing to switch back and forth between the large and small maps.
