Description

Multi-person online interaction method and system based on intelligent mobile terminal equipment

technical field

The invention relates to a new interactive method and system for multi-person simultaneous online on multiple intelligent mobile terminal devices, which is oriented to game entertainment and virtual reality applications, and belongs to human-computer interaction technology, virtual reality technology, online electronic games, and intelligent mobile terminals. applications, digital media and entertainment.

Background technique

At present, whether it is the world or China, the game industry is showing great vitality. The popularity of smart mobile terminal devices such as smartphones and tablet computers has brought great opportunities for the development of the game industry. According to Forrester Research's forecast, the global shipment forecast of smart mobile terminal equipment is shown in Figure 1. At the same time, with the development of hardware technology, the performance of smart mobile terminal devices is also rapidly improving, and smart mobile terminal devices have become a popular communication and entertainment device, which greatly expands the means of game interaction and provides More ways to play. They no longer need to buy special game devices, but can play games directly through smart mobile terminal devices. Smart mobile terminals here generally refer to display screens less than 7 inches, easy to carry, with mobile processors and operating systems, and wireless networks. Kinetic, smart phones with certain mobile computing capabilities (such as ipone, HTC, Samsung, etc.), or small tablet computers such as Samsung, Asus, etc., or other mobile electronic devices with the above characteristics.

However, the screen size and graphics processing capabilities of smart mobile terminal devices are limited after all, and cannot be compared with computers, so they cannot bring players a perfect game visual and performance experience.

In addition, current multiplayer games mainly have three interaction modes. The so-called interaction mode refers to the interactive behavior that can be potentially felt by the player. They can represent interactions that occur between players or between a player and the computer, and can be used to express player behavior towards one person as well as other people. Interaction modes allow behavior to be perceived by providing mutually palpable images and sounds in the game world. All in all, the sense of presence and psychological immersion is enhanced by the communication, coordination and cooperation brought about by this model. The application scenario of the first interactive mode is the multiplayer online online game mode. In this game mode, multiple people interact through the Internet and watch them on their own independent display devices. Therefore, the interaction between people has great potential. virtuality, which cannot bring the fun of the actual interactive game; the application scenario of the second interactive mode is to connect the game console through the gamepad to play multiplayer games at the same time, such as Sony’s Playstation series, Microsoft’s xbox series, etc. At this time, although The actual interaction between players is stronger, but this mode is greatly limited by the number of gamepads, and there is no browseable display interaction interface on the gamepad, and in most cases only supports the number of players with less than 4 players , it is impossible to realize the experience of multiplayer games in the true sense; the application scenario of the third interactive mode is handheld battle, such as PSP battle. Although this game mode supports a large number of people playing at the same time, players can only see The game screens on the small screens of their respective handhelds cannot get enough good audio-visual enjoyment of the game.

The invention provides an interactive method and system for digital game entertainment and distributed virtual reality application systems. The following description of the system takes online game applications as an example. The present invention focuses on the content of game interaction. For other important content such as game logic and game architecture, although the game system is important, if the game interaction method and system In unrelated aspects, the invention will not be described in detail. This game system uses an ordinary home or commercial computer as a game server node, uses the game server node to receive game control and interaction commands from users or players, runs the main program and cycle of the game, and is responsible for the control of the main game logic and the realization of game functions (through Including game scene management engine, physics engine, AI engine, network engine, animation engine, script engine, video and sound media engine, etc., a series of important parts of the game are realized) and the most important game screen drawing (or called For rendering, through the game rendering engine), the computer’s display device and sound output device (including display or display array, projector and projection curtain wall, immersive virtual reality display environment (CAVE), etc.) are used for game screen display and audio signals Output. The role of the smart mobile terminal device is the game control and interaction commands sent by the user or player to the game server node through the smart mobile terminal device. The device itself only provides a simple interactive graphical interface and game interaction and manipulation functions for the user or game player. , analysis and sending of user interaction commands, displaying the current game status according to the information sent by the game server node, etc. These functions have very low requirements on the computing performance and display performance of mobile devices. Thus, the final game mode is a working form of the following:

Multiple players hold smart mobile devices as game control and interactive terminals to form a group game mode, and jointly join the game scene, game story and game process executed by the game server node. All game players share the display output and audio equipment provided by the game server, so the current game screens seen by the game players in the current group are completely consistent. This will greatly enhance the group entertainment interaction and immersive experience of game players, and enhance the fun of interaction between game players.

Explain the following terms:

Game scene: The environment, buildings, machinery, props, etc. in the game are the virtual space in which game players live, including three-dimensional or two-dimensional, and are the background for the occurrence of game stories and the advancement of game progress. There may be only one game scene in a game, or there may be multiple game scenes that vary with the plot.

Game story: that is, the game plot, consisting of more than one set of specific events and conflicts that can show the relationship between people and the environment, and a series of events organized according to the logic of cause and effect. The game task framework and the game creative plan constitute a game story with a certain sequence and logic of thought content. Game stories are an important factor for classifying game types. For example, games with role-playing as the main content mostly have complex and lengthy game stories, while games with fighting as the main content usually have very simple game stories.

Game process: The game characters played by each other affect each other, and the status of the game characters will have a relationship and influence with each other. As time goes by, the game process continues to advance, and the game story is gradually completed, reaching the victory or defeat determination condition or the end of the game story.

In addition, the operation of the game server node can adopt either the online group mode or the offline group mode. The so-called online group mode means that when the game server node is running the game, it first connects to the main game server in the game control center (the main server is controlled and maintained by a dedicated server administrator). Server control, the main game server allows other game server nodes to join. When multiple game server nodes are connected and joined to the main server, the main server will perform communication and synchronous collaborative control functions. In this way, each game server node (these game server nodes can be arbitrarily distributed in different corners of the world) corresponds to a group of online game players playing games, and multiple game server nodes and their game players constitute a huge game Group, players in this game group can not only play different roles in the game, but also form some teams through some connection with each other to play the game, or even form a group to play against each other, and so on. In the above game modes, the relationship between the game server node and the main server is similar to the relationship between the online game client and the game center server in the traditional online game mode, and the function of the main server is also similar to that of the game center server in the traditional online game mode. The function is similar.

The so-called offline group mode is the game mode adopted by game players when the game server nodes do not connect to the main server (controlled by the group game players themselves), or when the main server cannot be connected. At this time, the process of the game running is the same as the previous process, that is, a game mode in which multiple players hold smart mobile devices as game control and interactive terminals to form a group, and jointly join the game scenes, game stories and games executed by a single game server node. game in progress. All game players share the display device provided by the game server node, so the current game screen seen by the game players in the current group is completely consistent.

The online group mode and offline group mode game scene diagrams of the game server nodes are shown in Figure 2 and Figure 3 respectively.

The technical solution of the present invention is a group game mode and system realized based on intelligent mobile terminal equipment, and its operating steps are:

1) Start the game server node and select the game running mode (it can be selected by the user through the mobile terminal or by the server node): offline group mode or online group mode. If you choose the online group mode, the game server node will send a connection request to the main server through the network (login verification mode or non-login verification mode is acceptable), once the connection with the main server is established successfully, the game will enter the online group mode, otherwise it will automatically transfer to offline group mode. In the offline group mode, users or players can only interact, control, communicate and interact within a group (everyone can see the real body of the user or player). In the online group mode, users can not only have virtual + real communication with members within the group, but also have virtual interactions with remote users or players who are not in the same group and cannot see their real bodies. When the game server node is started, a wireless network needs to exist or be created so that the node server can communicate with the mobile smart terminal device. In the communication process, data transmission can be carried out in any wireless way, either bluetooth or wifi or other wireless communication standards can be used. Using wifi in our system can have greater bandwidth and transmission rate (usually Desktop computers can use wireless routers, and laptop computers can use their own wireless network cards to establish wifi wireless networks).

2) Game players or users use the game client on the smart mobile terminal device (users must install it in advance), search for the wireless network where the game server node is located in the previous step, and then choose to join, so as to establish a wireless connection with the game server node. After the connection is successful, the game server node can send information to the mobile terminal, and the mobile terminal can also send information to the server, thereby establishing a two-way communication connection. The technologies used to send information are all existing mature technologies. For example, in the case of wifi, data transmission can follow TCP/IP protocol or UDP protocol, and commands and requests can use RPC (Remote Procedure Call, remote procedure call) protocol. Part of it is not the key point of the present invention, so it will not be described in detail. When a game player is ready to start the game, he can send a ready message to the game server node by clicking a button on the mobile device client, etc. The game server node saves the information of each mobile device connected to the network, and displays on the display device whether each user is ready.

3) When all users who want to participate in the same game server node have connected to the game server node and the status is displayed as ready, through the manual control operation of the server node or the manual operation of a user on the smart mobile device client, select Start game. If the former chooses to start the game through the server node, the server node first sends a message notification of starting the game to all mobile device clients that have successfully joined the game through the wireless network. After receiving the message, the client enters the game state and displays the corresponding screen. Send the feedback message of receiving the message to the game server node, and enter the game screen to officially start the game when the server node receives the feedback messages from all mobile devices; if the latter chooses to start the game through a user's operation on the mobile device, then First, the client sends a message to start the game to the server node. Afterwards, similar to the process of the previous case, the server node sends a notification to start the game to all other mobile devices. After receiving all the feedback notifications, it officially enters the game scene (similar to The "three-way handshake" used when a TCP connection is used to transfer data). Since the time between the server sending out the notification to start the game and receiving all the feedback messages is actually very short, the user will not see obvious pauses or out-of-sync phenomena on the screen of the mobile device. In the game scene and the current game process, the player acts as a certain virtual game character in the game, and starts to control the role of the game.

4) For players who have successfully entered the game, corresponding interactive prompts will be displayed on their smart mobile terminals. According to the prompt, the user controls the game character through the graphical interface and other special function units provided by the smart terminal. The user graphical interface on the smart mobile terminal includes: menus, buttons, direction wheels, scroll bars, virtual keyboards, and the like. Other special interactive functional units of the smart mobile terminal include a gravity sensing unit, an acceleration sensing unit, a multi-touch unit, and the like. The sensors of mobile terminals include gravity sensors, touch screens, microphones, cameras, etc. The physical signals they can capture respectively include gravity acceleration vectors, finger touch positions and the number of touching fingers, external real-time audio streams (including voice), external real-time video streams etc. These sensors in the new human-computer interaction model can truly convert the physical quantity of the external real operation into digital information, transmit it to the current client interaction system, and convert it into the user's operation instruction. The game server node can also retain a certain interactive graphical interface for controlling the overall progress of the game of all game users on the node, such as pausing the game and exiting the game. At the same time, users or players can freely choose their favorite interactive form (such as using a touch screen, gravity sensor, microphone or camera, etc.) through an interactive graphical interface, or a combination of these modes. All players connected to a common game server node (called group players) share a game screen, and the game screen is displayed on a public computer output display device, the virtual game role played by each player in the group players The game state at each moment is displayed on this public computer output display device, so the display device is often relatively large (such as large-size monitors, projection screens, large-screen TVs, display walls, etc.). Game players control game characters through interactive operations of mobile terminals, and mobile terminals recognize user interactive operations (existing mobile terminal devices provide ready-made APIs for identifying user interactive operations), and transfer recognizable user interactive operations to Translate into some corresponding control commands predefined in the system, and communicate the commands to the game server node through wireless data transmission or remote procedure call. After the game server node receives the player's control commands, it performs corresponding game logic processing according to the pre-defined processing methods for various commands in the program (the common implementation method is to use the state machine, that is, first judge whether the received one is command, and then enter the corresponding game state, perform a series of operations in the game state, until the next command is received, the state jumps into another game state), and the game screen output is displayed on the aforementioned display device. When necessary, the status information of the corresponding player is sent back to the mobile terminal, and the mobile terminal obtains the message sent from the server, and displays it accordingly on the mobile terminal.

5) When the game is running in the online group mode, the game server node communicates with the main server. The general server is responsible for functions such as synchronous and cooperative control between game server nodes, and maintains the data consistency of the state and attributes between each server node. The general server is only a logical concept, and its essence can be a server cluster, responsible for the implementation including Functions such as load balancing, server backup and mirroring, database backup and migration, etc., can be implemented using current mature architectures and systems.

6) When all user players on a game server node are disconnected from the server node, or when the master player connected to the current game server node chooses to end the game, the game task of the current game server node ends and exits. If the current game mode is an online group mode, the main server and other game server nodes continue to operate normally, and other group game players continue to play games normally without being affected.

Compared with prior art, the present invention has obvious advantages:

The innovation of the interactive mode of the present invention is shown in FIG. 6 . The present invention allows users to have interactive modes and experiences of multiple levels, multiple interactive interfaces and channels.

Multi-level interaction method:

The first level: users in the group can directly carry out face-to-face interaction (real interaction) between world entities (people) through each other's language, expression, gesture, body movement, etc., so as to share the same display screen and audio equipment on the display device Based on the same audio output above (without this prerequisite, the level is difficult to establish);

The second level: users in the group interact with each other through actions, language and other behaviors in the virtual world of the game or other forms, based on the management of the game server nodes in the group;

The third level: users in the group and users outside the group conduct virtual interaction with each other through actions, language and other behaviors in the virtual world or other forms, based on the central game server.

Multi-channel game interaction method:

The first channel: choose one of the interaction channels on mobile devices such as touch screen, gravity sensor, microphone or camera.

The second channel: the graphical interactive interface on the mobile device client (similar to the operation mode of the gamepad, etc.).

The third channel: any combination of channels of the above various interactive channels.

The fourth channel: through the game screen display and game audio output shared within the group.

The essence of the invention is to innovate and propose a human-computer + human-human hybrid interaction mode and implementation form, and realize the separation of the main human-computer interaction interface and interactive functions in the game from the game's main logic and main functions in the design of software modules , greatly improving the running speed of the game. The frequent game interaction in the game is performed on the interactive interface of the smart mobile device, and the main logic and computing functions of other games are realized on the game server node.

1) Compared with existing online games. Most of the existing online game modes and system architectures are that each player faces a game screen display device alone, and interacts with the game interface independently. Game players only create virtual connections in the virtual world of the game. In the game, there is no actual face-to-face real perception, experience, emotion and feeling connection and communication with other players, and it is impossible to directly see other players' expressions and hear other players' voices, thus limiting the game players in the game get. Interactive fun. And the game mode of the present invention can allow multiple players to face the display scene of the same game screen at the same time and place, so that the players can directly contact each other in the real real world, greatly enhancing the playability and performance of the game. Group interactive experience fun. As shown in Figure 6, the existing online game mode does not have the immersive experience brought by the first level of interaction.

2) Compared to existing multiplayer games. Existing multiplayer simultaneous games are mostly limited by the number of game handles (often only 1-4 players), so the number of players is also greatly limited. And the present invention can realize the real multiplayer game easily because adopt intelligent mobile terminal and computer server to carry out wireless communication. In addition, players no longer need to buy a specific game controller, but only need to install the game client on a cheap and popular smart mobile terminal; and players do not need to connect the game control device to the host computer hardware, avoiding the connection between the game controller and the host computer. The distance limitation and the entanglement of multiple cables may cause inconvenience to gamers. At the same time, smart mobile devices often have a variety of available interactive devices such as touch screens, gravity sensors, microphones, or cameras. These devices can be used as interactive channels for game interactive operations, thus greatly expanding the scope of game interactive channels. Extended functionality of mobile devices. Therefore, the threshold for participating in the game is greatly reduced, and the number of concurrently online games is increased. As shown in Figure 6, at present, this technology has the first-level interactive experience, but does not have the third-level interactive mode and the various interactive channels and interfaces we have listed, and it does not have the scalability of the number of people.

3) Compared with the existing handheld battle games. The existing handheld battle game mode does not have the immersive experience brought by the first level of interaction. The present invention can concentrate the main control and screen display of the game on the game server node, thus greatly reducing the requirements on the computing performance and display performance of the mobile device, and thus can run a more complex and huge game system. At the same time, the external large-size display device and external sound device of the game server node can provide players participating in the game with a more high-end audio-visual experience.

detailed description

The structure of the whole game system of the present invention is as shown in Figure 4.

The present invention is based on the multiplayer game interaction mode realized by the mobile intelligent terminal, and the system modules are shown in FIG. 5 . The whole game system is mainly composed of three parts, which are the client running on the smart mobile terminal device, the game server node running on the computer and the server on the main game server.

●Client module structure on intelligent mobile terminal equipment:

1) Client user interaction interface module. Control information for receiving user input. The client can provide users with interactive means through graphical interfaces such as buttons and dialog boxes, and can also convert the user's operation of the smart mobile device terminal into the role of the game through the unique characteristics of gravity sensing and multi-touch of the mobile smart terminal device. The operation allows the user to control the game flow and character behavior. The smart mobile terminal obtains the user's operation information on the graphical interface or other interactive methods, and converts interactive operations such as touch, click, slide, and gravity sensing into corresponding game interaction commands. The sensors of mobile terminals include gravity sensors, touch screens, microphones, cameras, etc. The physical signals they can capture respectively include gravity acceleration vectors, finger touch positions and the number of touching fingers, external real-time audio streams (including voice), external real-time video streams etc. These sensors in the new human-computer interaction model can truly convert the physical quantity of the external real operation into digital information and transmit it to the current client interaction system. After the interactive interface module recognizes the user's interactive operation, it translates the user's interactive operation into the control commands defined in the system according to the predefined rules. For example, the operation of tilting the mobile device to the left is translated into a control command for the game character to "move to the left"; or the operation of the user clicking a button on the mobile device is translated into a control command for the character to "attack".

2) Client logic module. It is the main loop control module of the game on the client side. It performs certain calculations and responds according to the user control commands passed in by the user interaction interface module of the client side and the server commands received by the command receiving module of the client side. It is controlled in the smart mobile terminal Logical jumps and state transitions inside the running game system. Usually, the logic module of the client can also be realized by a state machine, and the state transition is performed by judging the current state and the received command. At the same time, according to the state of the current player character (moving, fighting, death, etc.), instructions are issued to the graphic display module and the command sending module of the client. For example, when the client logic module is in the "normal" state, if a translated "attack" command is received from the user interaction interface module, the state of the client logic module jumps to the "attack" state; The server side receives the command of "running out of bullets", then the logic module of the client jumps to the state of "running out of bullets", and at the same time notifies the graphical interface to make a corresponding display (such as setting the attack button to a gray and unavailable state); if At this time, when the "role death" command is received from the server, the state of the logic module of the client terminal jumps to "death", and at the same time, the graphical interface module is notified to display the corresponding screen of the player's death. The above is just an example of a role-shooting game, but because the types of games vary widely, the design of the logic modules of the client is also various, which can be simple or complex. The specific design of the client logic module is closely related to the game design itself.

3) The client graphical interactive interface module. A corresponding graphical interactive interface is displayed on the smart mobile terminal device. The graphic interactive interface here should be distinguished from the graphic drawing (rendering) and display module of the game scene. This module is only responsible for displaying simple graphical interactive interfaces such as buttons, not for drawing and displaying game scenes. During the real game, after determining the position of the finger on the screen of the smart mobile terminal device, the player only needs to do simple operations such as pressing buttons, so most of the time the player watches the game server node's external display device, Instead of a graphical interface on the mobile terminal screen.

4) Client command sending module. Send the user interaction command information that needs to be sent to the game server node to the server node through the wireless network (complying with the wifi protocol or other short-range wireless network protocols). Generally, during the course of the game, the player's operations are frequent, and this module needs to continuously convert the user's operations into instructions and send them to the game server node. The frequency of sending commands by this module is very frequent.

5) Client command receiving module. Receive the information sent by the server, parse it and communicate it to the client logic module. Since the information transmission from the server node to the client is only required when a critical event occurs to the character (such as the death of the character), the command reception frequency of this module is generally not very frequent.

●The module structure of the game server node:

1) Game server node client command sending module. Send commands to the client on the smart mobile device, that is, the game state information currently managed by the game server node, the game progress and other commands that need to be sent to the smart mobile client through the wireless network, and update the game state of the client (as mentioned above). However, this part of the command is sent less frequently.)

2) Game server node client command receiving module. Receive the information sent by the client on the smart mobile device through the wireless network, analyze the user command from the received information, convert it into a command that the game logic module of the server node can receive, and convey it to the game logic module of the server node (from the above As mentioned in the text, the module receives commands very frequently.)

3) The game server node master server command sending module. If the game server node is running in the online group mode, send the command that the game server node needs to send to the main game server.

4) The general server command receiving module of the game server node. If the game server node is running in the online group mode, it needs to obtain information from the main game server to synchronize the game state. The above four modules are collectively called the communication module of the game server node.

5) Game server node game logic module. Responsible for the logic control and state transfer of the entire game, it is the core part of the entire game framework. According to the user commands received through the wireless network, the corresponding characters are controlled, and the interaction and influence between the characters and the characters and the characters and the environment are calculated, the game state is updated, the victory and defeat judgment detection is performed, and the game scene is changed according to the game progress to promote the game. The development of the story. The logic module of the server node usually needs to maintain a list to save all player information participating in the game (player user name, user id, selected role, some attributes of the role, player's wireless network connection status, etc.), when there is a new move When a device joins the game, it is added to the list; when a user drops or logs out, it is removed from the list. When the server sends and receives client messages, the user id assigned by the server program is used as the unique identifier to determine which game character the message sent by a user client is for, which user the message generated by a certain game character should be sent to, and which user The role has an effect with which role and so on. Logical jumps on the server side can usually also be implemented using state machines, where state transitions occur under specific states and conditions. The logic control and trigger conditions of the state machine have a lot to do with the design of the game itself, and it has high flexibility. Program designers can design it according to the actual situation during actual development. Taking the triggering condition of the game's victory or defeat determination as an example, multiplayer battle games can use "only one surviving player" as the determination condition, and multiplayer speed competition games can use "there is one player who reaches the finish line first" as the determination condition , Multiplayer cooperative games may use "completion of a specific task" as a judgment condition.

6) Game server node game drawing (rendering) and display output module. The most important part of the game display is to display the current game scene on the external display device on the server side. Since the advantages of hardware devices such as computer CPU and GPU on the server side can be utilized, high-quality pictures can be displayed, high-quality videos can be played, and large-scale three-dimensional scene rendering can be performed. As mentioned above, during the game process, most of the game process is displayed on the external display device and external audio device of the game server node, so the player's visual attention is concentrated on the external display device most of the time and the sound equipment, the picture of the game is obtained from the display device, and the sound of the game is obtained from the sound equipment.

7) Game server node user interaction interface module. Since most of the operation instructions can be issued by the set user (that is, the client with specific control authority), the server can simply provide a basic graphical interface, such as buttons for starting, pausing, and exiting the entire game. The user interaction interface is the game logic module that transmits these messages (such as common mouse and keyboard messages) to the game server node.

●Modular structure of the main game server (this part is not the core content of the present invention, but an auxiliary description of the innovative content of the present invention)
