In addition, the terms "including" and "having" and any variations of them represent non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes unlisted steps or units, or optionally also includes Other steps or units inherent to these processes, methods, products or equipment.

In the present invention, "embodiment" means that a specific feature, structure or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. In the specification, the appearance of the phrase in various positions does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art can understand that the embodiments described herein can be combined with other embodiments.

Fig. 1 is a schematic structural diagram of a game controller according to an embodiment of the present invention. The game controller 10 can be connected to the game console through wired communication or wireless communication. The game console can be a closed game platform or a handheld game platform that integrates a central processing unit and a graphics processor, or it can be a personal computer. The game console is connected to the display screen and realizes human-computer interaction through the game controller 10. The game controller 10 includes a housing 11. The housing 11 has an extension 15 extending outward, and the two extensions 15 constitute handles for the user to hold with the left hand and the right hand respectively. The user can hold the controller safely and stably through the handle. The panel of the housing 11 includes various input devices, such as a button 16 arranged on one side, a start button and a reset button arranged in the middle. In some specific scenarios, a small steering wheel may also be set. When the user holds the game controller 10 in hand, the panel faces the user in a regular position. The game controller 10 is also preferably provided with a speaker for playing a feedback sound effect formed based on user operations, or a vibration element is used to form a special vibration effect formed based on the operation. Various interfaces (such as a USB interface), various inertial sensors (such as an acceleration sensor, a gyroscope, and a magnetometer) can also be provided on the game controller 10. Of course, the handle can also be designed to be held with one hand, and the shape of the handle is not further limited here.

In addition, unlike the traditional game controller 10, the game controller 10 further includes a rolling ball 12, as shown in FIG. 1, the rolling ball 12 is arranged on the side of the game controller 10. The rolling ball 12 is integrally arranged in the housing 11, partly exposed on the panel of the housing 11, and the top of the exposed part is approximately flush with the panel of the housing 11. The user can easily use the rolling ball 12 with the thumb of one hand when holding the game controller 10 through the extension 15. The rolling ball 12 rotates relative to the housing 11 under the operation of the user. For the game controller 10 that requires low control flexibility, the rotation freedom of the rolling ball 12 may be restricted by the structure of the housing 11 so that it only rotates along the panel rotation axis parallel to the housing 11.

The rolling ball 12 is used to input the game operation direction to control the virtual perspective of the character or the movement and direction of the object in the game virtual environment. In the present invention, an identification pattern is provided on the outer surface of the rolling ball 12. As shown in Figures 3 to 5, there are at least two ways to generate the logo pattern. First, as shown in Figures 3 and 4, the logo pattern can be generated based on a set vector diagram. The set vector diagram is generated by software and includes a pattern composed of graphic elements. Graphic elements can be points, lines composed of multiple points, rectangles or polygons composed of multiple lines (as shown in Figures 3 and 4 in 121-1 to 121-7). Each graph has its corresponding algorithm formula, which can be directly generated by software. The color, shape, outline, size and screen position of each graphic element (that is, the plane coordinates of the graphic element) can be automatically stored in the file attributes of the vector diagram. The set vector diagram is converted into a three-dimensional image with the center of the rolling ball as the origin and the radius of the rolling ball as the radius, and the logo pattern is further sprayed on the outer surface of the rolling ball 12 according to the three-dimensional image. Of course, the rolling ball 12 can also be integrally formed in the form of 3D printing to have a logo pattern on its outer surface. Converting the set vector diagram into a three-dimensional image with the center of the rolling sphere as the origin and the radius of the rolling sphere can be realized by the setting algorithm in the existing three-dimensional imaging software, which is not the protection focus of the present invention, and will not be repeated here. As shown in Figs. 3 and 4, when the logo pattern is generated based on the set vector diagram, the set vector diagram is preferably composed of multiple points or multiple curved color blocks to facilitate image processing and recognition and reduce errors. After being converted into a three-dimensional image, the file attributes of the three-dimensional image include the color, shape, outline, size, and screen position of each graphic element, as well as the graphic element in the space coordinate system with the center of the rolling ball as the origin. s position.

As shown in FIG. 5, as another optional manner, the logo image can also be generated based on a set bitmap image. The set bitmap image is preferably a 256-color bitmap image, as shown in Figure 121-8. Set the bitmap image to convert each pixel of the image into a data, which is stored in one byte. The color and screen position of each pixel can be automatically stored in the file attributes of the bitmap image. The set bitmap image is converted into a three-dimensional image with the center of the ball as the origin and the radius of the ball as the radius, and the logo pattern is further sprayed on the outer surface of the ball 12 according to the three-dimensional image. Of course, the rolling ball 12 can also be integrally formed in the form of 3D printing to have a logo pattern on its outer surface. The conversion of the setting bitmap image into a three-dimensional image with the center of the rolling ball 12 as the origin can be realized by the setting algorithm in the existing three-dimensional imaging software, which is not the protection focus of the present invention, and will not be repeated here. As shown in Figure 5, when the logo pattern is generated based on the set bitmap image, the set bitmap image preferably has rich color and tone changes to vividly represent the natural scene, so that the combined appearance of the rolling ball 12 and the housing 11 More novel and attracting attention. After being converted into a three-dimensional image, in addition to the color and screen position of the pixel, the byte used to record the data of each pixel also includes the position of the pixel in the spatial coordinate system with the center of the rolling ball as the origin. .

An image acquisition module 13 is also provided in the housing 11. Specifically, the image acquisition module 13 is a camera or a camera assembly composed of multiple camera groups, preferably a single camera. As shown in FIG. 2, the image acquisition module 13 is preferably arranged directly below the rolling ball 12, that is, the optical axis of the camera and the center O of the rolling ball 12 are located on the same straight line. The image acquisition module 13 is used for continuously acquiring multiple rolling ball images and transmitting the rolling ball images to the direction recognition module 14 of the game controller 10. Specifically, the image acquisition module 13 graphically samples the outer surface of the rolling ball 12 at intervals of a certain period during the user's operation of the rolling ball 12, and records part of the markings on the surface corresponding to the rolling ball 12 and the image acquisition module 13 Pattern changes. The direction recognition module 14 is designed based on an independent MCU. Since the user operates the rolling ball 12 each time, the rolling ball 12 does not return to its original position. Therefore, after the direction recognition module 14 obtains a plurality of continuous rolling ball images, it first selects a positioning icon in the identification pattern, and determines the game operation direction corresponding to the current rolling of the rolling ball 12 according to the position changes of the positioning icons in the plurality of rolling ball images. The positioning icon is at least a complete positioning image unit. For the set vector diagram, the positioning image unit is a graphic element, and the graphic element can be at least one of a point, a line, and a surface. For setting a bitmap image, the positioning image unit is a pixel.

In the game, a control command for the movement or direction of an object usually needs to be input within a certain set time before it is judged to be valid. Therefore, the user will autonomously perform the rolling ball 12 operation within the effective operation time. To complete the control of the object. Based on this, the image acquisition module 13 is preferably configured to acquire the first rolling ball image when the motion of the rolling ball 12 is detected, and the first rolling ball image can be regarded as the reference image at the beginning of the current operation of the rolling ball 12. After acquiring the first rolling ball image, start timing and acquire the second rolling ball image during the effective operation timing period. The second rolling ball image is considered to be the comparison image of the rolling ball 12 at the end of this operation. The direction recognition module 14 selects the positioning icon from the identification pattern of the first rolling ball image, and determines the corresponding position of the positioning icon in the second rolling ball image relative to the positioning icon in the first rolling ball image. Based on the determined game operation direction, the movement of the object or the perspective of the virtual image is controlled based on the determined game operation direction. If the rolling ball 12 rotates relative to any one of the two axial directions on the XOY plane parallel to the panel as shown in FIG. 2, the positioning icon selected by the direction recognition module 14 will be relative to the first rolling ball image in the second rolling ball image. The original position of a rolling ball image forms a motion trajectory, and based on this motion trajectory, the operating direction of the rolling ball 12 can be obtained. Among them, the action of the rolling ball 12 can be detected based on a Hall sensor, and the effective operation action timing period is generated based on big data. The effective operation timing period corresponds to the average time for the user to perform a 12-direction operation of the rolling ball.

Figures 6 to 8 show a specific working mode for the direction recognition module 14 to recognize the rotating direction of the rolling ball 12, where a bitmap image is set as an example. As shown in Figure 6, the direction recognition module 14 selects the first A complete pixel in the rolling ball image is used as the positioning icon 20, and the positioning icon vector is generated after the positioning icon is selected

Which location icon vector

The center point of the rolling ball points to the positioning icon. If the direction recognition module 14 selects multiple pixels, the positioning icon vector can be any positioning image unit from the center point of the rolling ball to the positioning icon, that is, any one of the pixels; the positioning icon vector is also It can be that the center point of the rolling ball points to multiple positioning image units in the positioning icon, that is, a combination of multiple vectors of multiple pixels, that is, a vector cluster. As shown in FIG. 7, the direction recognition module 14 selects the same pixel point as the positioning icon in the second rolling ball image, and generates a positioning icon vector after selecting the positioning icon

In the second rolling ball image, locate the icon vector

Similarly, the center point of the rolling ball points to the positioning icon. The direction recognition module 14 can determine the direction of the current rolling ball 12 rotation according to the direction changes of the positioning icon vector in the first rolling ball image and the second rolling ball image. As shown in Figure 6 and Figure 7, the vector

Relative to vector

Downward movement means that the rolling ball 12 rotates downward, and the corresponding game operation control of the rolling ball 12 downward rotation is executed. If the positioning icon vector is a vector cluster, the direction of all vectors in the vector cluster is changed to the direction in which the rolling ball 12 rotates this time.

The game controller disclosed in the present invention determines the game corresponding to the rolling ball rotation by setting a rolling ball with an identification unit on the outer surface in the housing, and judging the game corresponding to the rolling ball rotation according to the change of the positioning icon in the multiple continuous rolling ball images collected by the image acquisition module The operating direction improves the accuracy of the control direction of the game controller. Compared with the joystick, the rolling ball is smoother and more flexible, and is more suitable for multiple direction switching operations in a short period of time, with higher comfort.

The invention also discloses a game system, which includes at least one game controller as disclosed in the above embodiments. For the specific structure and application mode of the game controller, please refer to the detailed description of the above-mentioned embodiments and the accompanying drawings of the specification, which will not be repeated here. In addition to the game controller, the game system also includes a game console. The game console can operably provide audio and video signals. The game console is provided with a graphics processor and an audio processor. The game console is connected to a display screen and a speaker. The game controller establishes wireless communication with the game console host.

FIG. 9 is a flowchart of a method for identifying the direction of game operation provided by an embodiment of the present invention. As shown in Figure 9, the method includes the following steps:

S101. Continuously obtain a plurality of rolling ball images of a rolling ball arranged on a housing of a game controller, wherein an identification pattern is provided on the outer surface of the rolling ball.

Specifically, in this embodiment, the rolling ball is specially designed to be different from the joystick in the prior art. The user can easily use the rolling ball with the thumb of one hand when holding the game controller. The ball smoothly rotates relative to the housing under the user's operation to input the game operation direction. There are at least two ways to generate the logo pattern on the outer surface of the rolling ball. First, the logo pattern can be generated based on a set vector diagram. Specifically, the set vector diagram is generated by software and includes a pattern composed of graphic elements. The graphic element can be a point, a line composed of multiple points, or a rectangle or polygon composed of multiple lines. Each pattern is directly generated by the software according to the set algorithm. The color, shape, outline, size and screen position (that is, plane coordinates) of each graphic element can be automatically stored in the file attributes of the vector diagram. Convert the set vector diagram into a three-dimensional image with the center of the rolling ball as the origin, and further print or paste the logo pattern on the outer surface of the rolling ball according to the three-dimensional image. The rolling ball and the logo pattern can also be 3D printed Made in one piece. The logo pattern can also be generated based on the set bitmap image. The setting bitmap image is preferably a 256-color bitmap image. Set the bitmap image to convert each pixel of the image into one data and use one byte to store it. The color and screen position of each pixel can be automatically stored in the file attributes of the bitmap image. Convert the set bitmap image into a three-dimensional image with the center of the ball as the origin and the radius of the ball as the radius, and further spray or paste the logo pattern on the outer surface of the ball according to the three-dimensional image, or use 3D printing One-piece rolling ball with logo design. After being converted into a three-dimensional image, the bytes used to record the data of each pixel include the color and screen position of the pixel, as well as the position of the pixel in the spatial coordinate system with the center of the rolling ball as the origin.

S102: Select a positioning icon from the logo pattern of the rolling ball image, and determine the game operation direction corresponding to the current rolling ball rotation according to the position changes of the positioning icons in the multiple rolling ball images.

Specifically, since the user operates the rolling ball every time, the rolling ball does not return to its original position. Therefore, after the direction recognition module obtains multiple continuous rolling ball images, it first selects the positioning icon in the identification pattern, and determines the game operation direction corresponding to the current rolling ball rotation based on the position change of the positioning icon in the multiple rolling ball images. The positioning icon is at least a complete positioning image unit. For the set vector diagram, the positioning image unit is a graphic element, and the graphic element can be at least one of a point, a line, and a surface. For setting a bitmap image, the positioning image unit is a pixel.

As shown in FIG. 10, the following steps are preferably performed when continuously obtaining a plurality of rolling ball images of rolling balls arranged on the housing of the game controller:

S201: Acquire a first rolling ball image when a rolling ball motion is detected;

S202: After obtaining the first rolling ball image, start timing and obtain the second rolling ball image when the effective operation action timing period is reached.

In the game, a control command for the movement or direction of an object usually needs to be input within a certain set time before it is judged to be valid. Therefore, the user will autonomously perform a rolling ball operation within the effective operation time to Complete control of the object. Based on this, it is preferable to set the first rolling ball image to be acquired when the rolling ball motion is detected, and the first rolling ball image can be regarded as the reference image at the beginning of the current operation of the rolling ball. After acquiring the first rolling ball image, start timing and acquire the second rolling ball image during the effective operation timing period. The second rolling ball image is considered to be the comparison image at the end of the rolling ball operation.

Further select the positioning icon in the logo pattern of the rolling ball image, and perform the following steps when judging the game operation direction corresponding to this rolling ball rotation according to the position change of the positioning icon in the multiple rolling ball images:

S203: Select a positioning icon from the identification pattern of the first rolling ball image;

S204: Determine the game operation direction corresponding to the current rolling ball rotation according to the position change of the positioning icon in the second rolling ball image relative to the middle positioning icon in the first rolling ball image.

Specifically, the positioning icon is selected from the logo pattern of the first rolling ball image, and the position change of the positioning icon in the second rolling ball image relative to the positioning icon in the first rolling ball image is determined to determine which rolling ball corresponds to this time. The game operation direction, and the movement of the object is controlled based on the determined game operation direction. If the rolling ball rotates relative to any one of the two axial directions on the XOY plane parallel to the panel as shown in Figure 2, the selected positioning icon will be relative to the original image of the first rolling ball in the second rolling ball image. The position forms a motion trajectory, and based on this motion trajectory, the direction of the rolling ball operation can be obtained. Among them, the motion of the rolling ball can be detected based on a Hall sensor, and the effective operation timing period is generated based on big data. The effective operation timing period corresponds to the average time for the user to perform a rolling ball operation.

As a preferred step, after selecting the positioning icon, a positioning icon vector is generated. The positioning icon vector points from the center of the rolling ball to at least one positioning image unit in the positioning icon; according to the change of the positioning icon vector in the first rolling ball image and the second rolling ball image, determine the game operation direction corresponding to this rolling ball rotation .

Specifically, a complete pixel or graphic element in the first rolling ball image is selected as the positioning icon, and a positioning icon vector is generated after selecting the positioning icon, wherein the positioning icon vector points from the center point of the rolling ball to the positioning icon. If the direction recognition module selects multiple pixels, the positioning icon vector can be any positioning image unit from the center point of the rolling ball to the positioning icon, that is, any one pixel; the positioning icon vector can also be It is the center point of the rolling ball pointing to multiple positioning image units in the positioning icon, that is, a combination of multiple vectors of multiple pixels, that is, a vector cluster. Continue to select the same pixel or graphic element as the positioning icon in the second rolling ball image. After selecting the positioning icon, a positioning icon vector is generated. In the second rolling ball image, the positioning icon vector is also from the center point of the rolling ball Point to the location icon. The direction recognition module can determine the direction of the current rolling ball rotation according to the direction changes of the positioning icon vector in the first rolling ball image and the second rolling ball image. As shown in Figure 6 and Figure 7, the vector
