Description

Technical Field

[0001] This application relates to the field of gaming device technology, and more particularly to a game controller and gaming device. Background Technology

[0002] With continuous technological innovation, users' pursuit of high-quality gaming experiences is growing stronger, and gaming devices such as game controllers, game consoles, and VR devices are gaining popularity among gamers. Among these, game controllers have become particularly favored due to their precise control, comfortable operation, social interaction, and rich functionality. However, traditional game controllers, due to their specific product definition and structural design, have failed to fully unleash the operational potential of players' hands. For example, professional esports players, in order to accurately control multiple buttons and joysticks simultaneously during intense competitions, often use "C-hand" grips and other control methods to hold game controllers for extended periods, leading to occupational injuries such as tenosynovitis. Therefore, how to improve the structural design of game controllers to enhance the player's control experience and better meet players' demands for comfort, precision, and other high-quality gaming experiences has become an urgent problem to be solved. Summary of the Invention

[0003] In view of this, this application proposes a game controller and game device, which have the advantages of being stable and reliable and having controllable cost.

[0004] In a first aspect, this application proposes a game controller, the game controller comprising:

[0005] The main body includes a left grip portion, a right grip portion, a front operation portion, and a rear operation portion. The front operation portion includes a left operation area and a right operation area, and the rear operation portion includes a left back area and a right back area. The left back area corresponds to the left operation area, and the right back area corresponds to the right operation area.

[0006] A control component is disposed on the front operation section, and the control component includes a first joystick component;

[0007] A back key assembly, the back key assembly including a first back key group, the first back key group including at least three back keys, and the distance between any two back keys in the first back key group is less than or equal to 25mm;

[0008] Wherein, the first joystick is disposed in the left operating area, and the corresponding first back button group is disposed in the left back area; or, the first joystick is disposed in the right operating area, and the corresponding first back button group is disposed in the right back area.

[0009] Secondly, this application proposes a gaming device, which includes the game controller described in any embodiment of this application.

[0010] The game controller and gaming device proposed in this application are provided with a first back button group corresponding to the first joystick on the front. The first back button group may include at least three back buttons, and the distance between any two back buttons is less than or equal to 25mm. This allows players to operate the joystick with their thumb on the front of the game controller while simultaneously controlling multiple buttons with the fingers on the back of the game controller using the same hand. This enables operations such as "jump aiming," "jump scope," and "using complex skills while moving." Based on a comfortable grip, this provides a more precise, sensitive, rich, and comfortable control experience and improves the win rate of e-sports players. Attached Figure Description

[0028] In the gaming industry, users' pursuit of high-quality gaming experiences constantly motivates gaming equipment manufacturers to improve their products and innovate their technologies. With the continuous development of the gaming industry and living standards, many players often choose gaming devices such as game controllers, game consoles, and VR devices to pursue a higher quality gaming experience. Among these, game controllers have gained widespread popularity due to their precise control, comfortable operation, social interaction, and rich functionality. However, traditional game controllers, due to their specific product definition and structural design, still have room for improvement in terms of control precision and comfort. For example, the specific structure of traditional game controllers limits the grip, especially since the left and right joysticks, four directional buttons, and four action buttons (A / B / X / Y or ○ / △ / □ / ×) can generally only be controlled by the player's left and right thumbs. This means that players can often only accurately control a maximum of two buttons or joysticks at a time, restricting movement in games and making it difficult to meet the increasingly complex gameplay of today. Therefore, some manufacturers began to add mapped buttons (back buttons) to the back of game controllers, reducing the workload of the middle finger on the thumb. Most game controllers with mapping functionality have four back buttons, two on each side. Players must make trade-offs, only setting the four most frequently used front buttons as back buttons, and need to set different button mappings for different games. Players also need time to practice to improve their proficiency and muscle memory. Because the number of back buttons is insufficient to map all the frequently used front buttons, and the arrangement of back and front buttons is different, the player's thumbs are not completely freed from the front buttons (i.e., players still need to move their thumbs away from the joysticks to click the front buttons during gameplay). For most players, this undoubtedly requires a significant learning curve. Due to this limitation of back buttons, some professional esports players don't use traditional mapped button controllers in competitions. Instead, they adopt a "C-hand" grip, using only their middle, ring, and little fingers, while placing their index finger and thumb on the front of the controller to ensure precise control of more buttons or joysticks simultaneously. This has led to occupational injuries such as tenosynovitis. Therefore, by improving the controller's structural design and button layout, such as arranging the back buttons in a similar number and order to the front, the burden on the player's thumb is reduced, significantly lowering the learning curve, improving the player's controller experience, and better meeting players' demands for a comfortable, precise, and high-quality gaming experience.

[0029] To resolve the above issues, please refer to [link / reference]. Figures 1 to 3 , Figure 1 This is a first-view perspective three-dimensional structural diagram of a game controller according to one embodiment of this application. Figure 2 This is a schematic diagram of the second-view stereoscopic structure of the game controller in one embodiment of this application. Figure 3 This is a third-person perspective stereoscopic structure diagram of a game controller according to one embodiment of this application. Figure 4 This is a schematic diagram of the fourth-view three-dimensional structure of a game controller in one embodiment of this application.

[0030] like Figures 1 to 4 As shown in the figure, this application embodiment proposes a game controller 100. The game controller 100 may include a body 10, a control assembly 20, and a back button assembly 30. The body 10 may include a left grip 11, a right grip 12, a front operation part 13, and a back operation part 14. The front operation part 13 may include a left operation area 131 and a right operation area 132, and the back operation part 14 may include a left back area 141 and a right back area 142. The left back area 141 corresponds to the left operation area 131, and the right back area 142 corresponds to the right operation area 132.

[0031] Specifically, the control component 20 can be located on the front operation section 13. The control component 20 may include a first joystick 21, and the back button component 30 may include a first back button group 31. The first back button group 31 may include at least three back buttons 33. Since the back buttons need to be operated by the user's fingers placed on the back operation section 14 of the game controller 100, the distance between any two back buttons 33 in the first back button group 31 may be less than or equal to 25mm.

[0032] Furthermore, in the first back key group 31, the distance between any two back keys 33 is less than or equal to 15mm.

[0033] Furthermore, in the first back key group 31, the distance between any two back keys 33 is less than or equal to 10mm.

[0034] This design allows users to perform a variety of operations by controlling the first back button group 31 and the joystick, making it possible to perform actions such as "jump aiming," "jump scope," and "using complex skills while moving" with one hand. When users want to control the front button group and joystick on the same side, they no longer need to use unhealthy grip and control techniques such as "C-hand," thereby improving the player's gamepad control experience and better meeting the player's needs for a flexible, comfortable, precise, and healthy high-quality gaming experience. It brings a more precise, sensitive, rich, and comfortable control experience and improves the win rate of e-sports players.

[0035] Understandably, given the different hand sizes and finger lengths of different users, how to configure the position, layout, and shape of the first back button group 31, and other structural design elements, to improve the player's controller experience and better meet the player's needs for a high-quality gaming experience in terms of comfort, precision, and flexibility, has become an issue that requires further consideration.

[0036] Specifically, the first back button group 31 can be set at the position corresponding to the first joystick 21 on the back operation part 14, so that the user can operate the first joystick 21 with the same hand when operating the first back button group 31.

[0037] For example, the range corresponding to the left back region 141 can satisfy the following relationship:

[0038]

[0039] Wherein, d1 is the maximum length of the game controller 100 from the left side of the left grip 11 to the right side of the right grip 12, d2 is the length from the left back area 141 to the left side of the left grip 11; and / or, the range corresponding to the right back area 142 can satisfy the following relationship:

[0040]

[0041] Wherein, d1 can be the maximum length of the game controller 100 from the left side of the left grip 11 to the right side of the right grip 12, d3 can be the length from the right back area 142 to the right side of the right grip 12; and / or, the shortest distance from the center position of the first back button group 31 to the side edge 121 of the corresponding left grip 11 or right grip 12 can be 1-75mm.

[0042] Furthermore, the shortest distance between the center position of the first back button group 31 and the side edge 111 of the corresponding left grip 11 or the side edge 121 of the right grip 12 can be 20-70mm.

[0043] Furthermore, the shortest distance between the center position of the first back button group 31 and the side edge 111 of the corresponding left grip 11 or the side edge 121 of the right grip 12 can be 40-60mm.

[0044] Since setting the first back button group 31 on the back of the game controller 100 changes the traditional product definition and structural design of the game controller 100, the traditional grip method and operation mode will also be changed. In order to reduce the difficulty for users to learn, remember and adapt to the new product, improve the player's eye-hand reaction speed, and facilitate the formation of control muscle mapping, at least a portion of the back buttons in the first back button group 31 can have a mapping relationship with at least a portion of the buttons on the front of the game controller 100 in terms of function, structure or pressing method.

[0045] In some embodiments, the first button group may include at least four front single buttons 22, and the first back button group 31 may include at least four single back buttons 331. The layout of the four front single buttons 22 may correspond to the layout of the four single back buttons 331.

[0046] Please refer to the supplementary information. Figure 5 , Figure 5 This is a three-dimensional structural diagram of a game controller according to another embodiment of this application. Figure 5 As shown, in some embodiments, the first back key group 31 may include at least four single-piece back keys 331, wherein the four single-piece back keys 331 may be arranged in a quadrilateral layout such as "rhomboid four corners", "rectangular four corners" or "trapezoidal four corners"; and / or, the first back key group 31 may include connected keys 332 such as "square", "cross", "triangle" or "circle".

[0047] Furthermore, the rear operation section 14 may also be provided with function keys 35, which can be configured as programming keys, menu keys, combination keys, etc., and can take the form of a paddle, joystick, switch, etc., without being specifically limited here.

[0048] In some embodiments, the control component 20 may further include a first button group, and there is a functional mapping relationship between the first button group and the first back button group 31. With this configuration, players can judge the layout and / or function of each back button in the first back button group 31 on the back of the game controller 100 by looking at or following the operating habits of the first button group on the front of the game controller 100, thereby improving reaction speed and enhancing the game control experience.

[0049] Understandably, due to different player preferences and the varying operational requirements of different games, players need to adjust the specific form of the back buttons, such as single / connected, cross / diamond shapes, to make the gamepad 100 more comfortable to use. Therefore, the structure of some single-button back buttons 331 can be made compatible with standardized kits such as cross-shaped keycaps and square keycaps, so that players can choose a suitable kit at a lower cost.

[0050] For example, the first back key group 31 may include at least three single back keys 331, which can be used with different forms of integrated keycaps such as "square", "cross", "triangle" or "round" to form integrated keys 332.

[0051] Understandably, to further improve operating efficiency and user experience, the back button assembly 30 may also include a second back button group 32. Specifically, the first back button group 31 is located in the left back area 141, and the corresponding second back button group 32 is located in the right back area 142; or, the first back button group 31 is located in the right back area 142, and the corresponding second back button group 32 is located in the left back area 141.

[0052] Furthermore, the number, form, shape, or layout of the back keys 33 in the second back key group 32 can correspond to those in the first back key group 31. The "form" can include single-piece / integrated keys, the specific mechanical structure of the keys, or detachable / non-detachable key types. The specific mechanical structure of the keys can include paddle keys, dome keys, and keyboard switches. The "shape" can include key width, key shape, or key texture. This design makes it easier for users to distinguish between different back keys 33, reducing the difficulty of learning, memorizing, and adapting, and facilitating the formation of muscle memory.

[0053] Please refer to the supplementary information. Figure 6 , Figure 6 This is a three-dimensional structural diagram of a game controller according to another embodiment of this application. In some embodiments, depending on user preferences, game type, or other actual needs, the number, form, shape, or layout of the back buttons 33 in the second back button group 32 may not correspond to the first back button group 31, or may not completely correspond to the first back button group 31. For example, the first back button group 31 is a combination of single back buttons 331, and the second back button group 32 includes at least one integrated button 332.

[0054] It is understandable that different users have different finger sizes and widths. Keyboards that are too wide make it difficult for users to quickly switch keys, while keys that are too narrow make it difficult to design appropriate tactile feedback and may lead to accidental presses. For example, the minimum width of at least one back key 33 could be set to 1-40mm. Alternatively, the minimum width of at least one back key 33 could be set to 1-20mm. Yet another example is a minimum width of 1-12mm.

[0055] Understandably, users may prefer a different tactile feel for the back buttons compared to the front buttons. This tactile feel can be improved by adjusting the actuation point or total travel, thereby enhancing the gaming experience. For example, at least one back button 33 could have an actuation point or total travel of 0.1-20mm. Alternatively, at least one back button 33 could have an actuation point or total travel of 0.1-10mm. Or at least one back button 33 could have an actuation point or total travel of 0.1-4mm.

[0056] In some embodiments, the tactile feedback of the buttons can be improved by setting a range of pressure applied, thereby enhancing the gaming experience. For example, the pressure applied to at least one back button can range from 1 to 300 gf. Alternatively, the pressure applied to at least one back button can range from 1 to 250 gf. Yet another example is a pressure applied to at least one back button ranging from 1 to 160 gf. For instance, the pressure applied to at least one back button can range from 65 to 120 gf.

[0057] Since the back buttons are located in the user's blind spot when holding the game controller 100, how to avoid accidental touches, reduce the difficulty for users to perceive the back buttons, and thus improve control accuracy and gaming experience has become a problem.

[0058] In some embodiments, the center of the first back key group 31 is a smooth surface; and / or, the center of the first back key group 31 is textured; and / or, at least one back key 33 has a textured surface; and / or, the shape of the surface of at least one back key 33 differs from the shape of the surface of at least one other back key 33. This configuration enhances the recognizability of different back keys 33, making it easier for users to distinguish between them. Furthermore, since the center of the first back key group 31 is often located among multiple back keys 33, it facilitates the user's differentiation between the center and the back keys 33, allowing for quick location of the back keys 33, reducing accidental touches, and enabling rapid identification of the target back key 33 during operation, thus providing a highly sensitive and responsive gaming control experience.

[0059] It is understood that the back button does not have to be a press-type button. For example, the rear operation section 14 may be provided with a touchpad, and at least one back button 33 may be a virtual button of the touchpad; and / or, the back button assembly 30 may include a touch sensor to realize the touch operation of the back button; and / or, at least one back button 33 may be provided with a press sensor.

[0060] In some embodiments, the game controller 100 may also be provided with at least one shoulder button 40. The shoulder button 40 is located on the same side as the first back button group 31, with the center of the first back button group 31 positioned such that when the user's thumb contacts the first joystick 21 and the index finger contacts the shoulder button 40, the tip of the middle or ring finger can reach the rear operation section 14. This arrangement, based on comfortable operation of the first back button group 31, further unleashes the user's finger control potential and improves the user's control and gaming experience by reasonably adjusting the placement of the shoulder button 40.

[0061] In some embodiments, since the operation mode and perception pattern of the back of the game controller 100 are different from those of the front, and the button perception will also differ for different hand sizes, in order to reduce the difficulty of operation adaptation or adapt to different hand sizes and improve operation comfort, the back button assembly 30 can also be adjusted in position via a base. For example, the back button assembly 30 may also include a base, with a first back button group 31 disposed on the base, and the base is adjustablely disposed on the back operation section 14 so that the first back button group 31 can translate and / or rotate relative to the back operation section 14.

[0062] Understandably, for different games, users may need to temporarily remove or replace different types of back buttons 33 to avoid accidental presses or to improve the gaming experience. Back buttons 33 can be installed as a whole on the back of the controller, or they can be installed individually on the back of the controller. For example, at least one back button 33 can be detachably connected to the game controller 100. This back button can be magnetically connected and / or snap-fit ​​connected to the game controller 100.

[0063] Understandably, to provide a better grip experience for users, the left grip portion 11 and the right grip portion 12 can be positioned relative to the axis of the main body 10. Specifically, at least a portion of the left edge of the left grip portion 11 can be tilted relative to the axis of the main body 10, and / or at least a portion of the right edge of the right grip portion 12 can be tilted relative to the axis of the main body 10, so that when the user holds the corresponding grip portion of the game controller 100 and operates the back button 33 with their middle finger, the maximum angle between the ring finger and middle finger of the same hand is 0 degrees to 60 degrees.

[0064] Furthermore, by adjusting the shape of the grip, when the user holds the corresponding grip of the game controller 100 and operates the back button 33 with the middle finger, the maximum angle range between the ring finger and the middle finger of the same hand can be 0 degrees to 50 degrees.

[0065] Furthermore, by adjusting the shape of the grip, when the user holds the corresponding grip of the game controller 100 and operates the back button 33 with the middle finger, the maximum angle range between the ring finger and the middle finger of the same hand can be 0 degrees to 40 degrees.

[0066] It is understandable that, for the convenience of storage or use with devices such as mobile phones, at least a portion of the left grip 11, right grip 12, front operation part 13, or rear operation part 14 may be detachably provided to the main body 10.

[0067] Please see Figure 7 , Figure 7 This is a three-dimensional structural diagram of the game controller 100 in another embodiment of this application. Figure 7 As shown, the rear control unit 14 may also be provided with a raised seat 34, which may include at least three back buttons 33. The raised seat 34 can cooperate with the first back button group 31 and can be set on the rear control unit 14. This setting can better fit the posture of the human hand when holding the game controller 100, which is more in line with ergonomic principles and brings a more precise, more sensitive and more comfortable control experience.

[0068] This application also proposes a gaming device, which may include a game controller 100 as described in any embodiment of this application. For example, the gaming device may include a game console and a game controller 100 as described in any embodiment of this application, and the game controller 100 may be communicatively connected to the game console.

[0069] Please see Figure 8 , Figure 8 This is a schematic block diagram illustrating the structure of a gaming device according to one embodiment of this application. Figure 8 As shown, in some embodiments, the gaming device 200 may include a display device 220, a game console 210, and at least one game controller 100. Further, the gaming device 200 may also include multiple game controllers 100, or split one game controller 100 into two sub-controllers for dual-player operation. The gaming device 200 may also include only the game console 210 and at least one game controller 100, excluding the display device 220. This configuration is compatible with the needs of multiplayer home games, such as team matches, online matches, or multiplayer battles. Furthermore, due to the back button configuration, when one game controller 100 is split into two sub-controllers, the sub-controllers can also fully utilize the control potential of the back buttons, maintaining a certain level of operational richness and improving the user's gaming experience.

[0070] Without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples.

[0071] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
