[0023] Please refer to Figure 1 The visual programming game host based on matrix input and output and knob encoder comprises: The visual programming platform includes graphical programming for game development on the Web side, game logic is built by dragging graphical modules, after real-time debugging through the simulator, game logic data is sent to the server side; The server side receives game logic data after receiving the application from the Web side, compiles it into a bin file that can run on the hardware side, and pushes it to the user's device; The hardware side includes an ESP32 chip module, a double-knob encoder, a matrix module, a display screen, and a memory; the chip module connects the double-knob encoder and the matrix input-output module through the GPIO interface, connects the display screen through the SPI bus, and connects the memory through the built-in external storage space interface; the memory is used to store multiple bin format game files; The double-knob encoder detects the rotation direction through phase difference and supports independent control of the movement and function triggering of game characters; The matrix module includes a key array and corresponding RGB LED light groups, and has input operation and pixel-level visual feedback functions.

[0024] Specifically, the visual programming platform uses OpenBlock graphical programming language, including graphical programming interface, simulator, and compiler; after the user builds game logic by dragging graphical modules, the simulator in the device-based Web side simulates and debugs the game, the simulator verifies the logic validity in real time, if the user completes the debugging, sends an application to the server side, the server will translate OpenBlock code into C code; and compile it into a target bin file, and then push the file to the user's bound device; the server side automatically converts game logic into C language code, and compiles it into a bin file that can run directly on the hardware side, plays a core role in reducing the technical threshold of game development and simplifying the development process, so that users without programming foundation (such as children and educators) can complete game logic design through intuitive modular operation without mastering professional code knowledge, the platform automatically completes code generation and compilation, realizes the convenient development experience of "creative drag and get", at the same time ensures that the generated bin file can be directly adapted to the hardware of the game console, and connects the whole process from creative design to console running, significantly improves the feasibility and efficiency of user participation in game creation, and promotes the formation of a popular game development ecosystem.

[0025] Specifically, the Web side also includes community interaction functions, including user registration and login, game work browsing, liking, commenting, scoring, and work uploading and downloading functions.

[0026] It needs to be explained that through the community interaction function provided with the APP terminal or WeChat applet, an open and active user ecological system is built. On the one hand, users can conveniently show personal creative achievements (upload works) and obtain feedback from others (likes, comments, scores), thereby stimulating the enthusiasm of creation; on the other hand, through browsing and downloading rich game works in the community, users can not only obtain diversified game experience at low cost, but also form social connections in interaction, thereby enhancing user stickiness.

[0027] Specifically, the display screen is specifically TFT-LCD or OLED screen, and the display content of the display screen includes game score, next block shape, game prompt information, and the display content is updated in real time by the ESP32 chip according to the game logic; Its core role is to provide clear and timely auxiliary information display for users, and enhance the smoothness and strategy of game experience; for example, in the "Tetris" game, the screen pre-visualizes the shape of the next block, which can help users plan the layout in advance; the real-time updated score intuitively reflects the game progress, thereby improving the sense of achievement; and the game prompt information (such as operation guide, state warning) reduces the operation threshold of users and ensures the interaction efficiency. Through the pixel-level display complementary to the matrix module, the display screen focuses on the presentation of dynamic data and strategic information, so that the allocation of hardware resources is more reasonable, and users can simultaneously obtain operation feedback (matrix LED) and global information (screen display), thereby optimizing the immersive game experience.

[0028] Specifically, the double-knob encoder identifies the rotation direction through the phase difference of two IO pins, and the A phase leading the B phase is forward rotation, and vice versa is reverse rotation, and the angle measurement is realized through pulse counting.

[0029] Specifically, the display screen is built-in power consumption management unit, which dynamically adjusts the refresh rate and backlight brightness according to the user operation frequency and game state, specifically: Let the user operation frequency be f, set the high frequency threshold , the low frequency threshold , the game state s (where s=1 indicates that the game is running, and s=0 is paused), and the refresh rate r and the backlight brightness b adjustment rules are set accordingly:

[0030] Among them, when the game is running (s=1), the refresh rate is dynamically adjusted according to the operation frequency (high , medium , and low ), and the brightness remains , and when the game is paused (s=0), the refresh rate is fixed , and the brightness is uniformly reduced to the preset brightness .

[0031] Specifically, the server side adopts a collaborative filtering recommendation algorithm, constructs a user-game interaction matrix, uses singular value decomposition for dimension reduction, calculates the similarity according to a preset formula, and generates personalized game recommendations, specifically including the following steps: Collect the game behavior data of users fed back to the server side through their respective hosts, including game browsing, downloading, playing time and scoring; the server side includes a data processing unit, which constructs a user-game interaction matrix according to the game behavior data through the data processing unit, wherein the matrix elements are the scores of users on games; In order to reduce the data dimension and calculation complexity, singular value decomposition algorithm is used to reduce the dimension of the sparse matrix; Based on the reduced matrix, the cosine similarity between users or games is calculated, and the formula is , wherein and are the score vectors of users u and v respectively, represents the similarity between users u and v, and the similarity of user interest is measured by the formula; According to the similarity calculation result, the games loved by other users similar to the target user are weighted and summed to generate a Top-N recommendation list; and the recommendation system update frequency is preset, and the combination of real-time update and daily early morning full update is adopted; real-time update is completed within a set time after user operation, and responds to the latest user behavior in time; daily early morning full update recalculates the recommendation list of all users to adapt to the long-term changes of game library and user interest.

[0032] It should be noted that the server side adopts a collaborative filtering recommendation algorithm, constructs an interaction matrix by collecting user game behavior data and reduces the dimension, calculates the interest correlation between users or games based on the cosine similarity formula, and plays a core role in accurately matching user interest and improving content distribution efficiency. Specifically, by analyzing the user's browsing, downloading, scoring and other behaviors, the system can automatically identify similar interest groups and recommend high-score games to potential interested users (such as users who like "Snake" may receive "Tetris" recommendation), while real-time updating (short time after user operation) quickly responds to changes in user preferences, avoiding recommendation lag, and daily full update ensures that the recommendation list is continuously optimized with the expansion of the game library and the evolution of user interest.
