Description

Technical Field

[0001] This utility model belongs to the field of projection game technology, specifically relating to a virtual scene simulator for interactive projection games. Background Technology

[0002] With the booming development of the digital entertainment industry, interactive projection games have gained popularity among users due to their unique appeal in breaking down the boundaries between virtual and reality. In these game scenarios, "instant feedback" is a core element in enhancing user experience. Users crave immediate responses to their every action on the game screen, thereby achieving a smooth and immersive interactive experience.

[0003] However, traditional interactive projection devices currently have significant shortcomings in practical applications. The various modules of these devices often operate independently, lacking an effective collaborative mechanism. This results in significant delays in data flow. Throughout the entire chain from user input to game screen feedback, the lack of continuity in information transmission and processing between modules leads to a long response cycle from motion recognition to screen updates. This makes it difficult to meet the high standards of real-time feedback required by game scenarios, severely impacting the real-time nature and smoothness of the interaction. Utility Model Content

[0004] The purpose of this invention is to provide a virtual scene simulator for interactive projection games, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a virtual scene simulator for interactive projection games, comprising:

[0006] A machine base, the bottom of which is connected to several support legs;

[0007] A bracket is provided on one side of the machine and connected to the machine. A projection component is provided inside the bracket, which is used to project the game screen onto the machine.

[0008] A data acquisition component is installed inside the machine and is used to acquire the game actions of the game participants in the game screen on the machine, including the actions of the game participants touching the projected screen on the machine with their limbs.

[0009] A positioning component, located inside the machine, is used to acquire the coordinates corresponding to game actions;

[0010] An update component, located inside the machine, is used to update the game screen on the machine according to the trigger action corresponding to the coordinates.

[0011] Preferably, the top of the machine is equipped with a projection panel, and the projection component can project the game screen onto the projection panel.

[0012] Preferably, the projection component includes a projector, which is located inside the top of the bracket. A first projection control motherboard and a second projection control motherboard are located inside the back of the bracket, and both the first and second projection control motherboards are electrically connected to the projector. The two motherboards are connected to the projector to realize projection control.

[0013] Preferably, the positioning component includes a game motherboard, which is located inside the machine and is used to convert the collected motion data into precise coordinates. The game motherboard in the positioning component converts the collected motion data into precise coordinates.

[0014] Preferably, the update component includes a control module integrated on the game motherboard, which is used to generate a new screen based on coordinates and control the projector to project the image.

[0015] Preferably, the machine is equipped with a hockey mainboard, and both the hockey mainboard and the game mainboard are electrically connected to a power supply box on one side. The game mainboard has an amplifier board and a power supply on both sides respectively. One end of the power supply is electrically connected to the power strip inside the machine through a plug. The hockey mainboard is installed inside the machine and is connected to the game mainboard through the power supply box, etc., to achieve power supply.

[0016] Preferably, the machine is equipped with a fan, and the projection board has a number of air outlets evenly distributed. The fan in the machine works in conjunction with the air outlets on the projection board to assist the ball in sliding on the table to improve the smoothness of the sliding.

[0017] Preferably, the bottom of the support leg is rotatably connected to a caster wheel, which facilitates the movement of the equipment.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) Through integrated structural design, the acquisition component, positioning component and update component are integrated inside the machine, and the update component is directly integrated on the game motherboard. This reduces the data flow delay caused by independent operation between modules in traditional equipment, and the response cycle from action input to screen feedback is significantly shortened, meeting the high requirements of game scenarios for real-time feedback and enhancing the user's immersive experience.

[0020] (2) The dual motherboard design of the first projection control motherboard and the second projection control motherboard is adopted and electrically connected to the projector. This enables redundant backup of the projection function, reduces the risk of equipment downtime caused by a single motherboard failure, and ensures continuous and stable output of the projected image.

[0021] (3) A fan is installed inside the machine, and several air outlets are evenly distributed on the projection board. The airflow from the air outlets on the projection board forms an "air cushion effect" at the bottom of the ball, which effectively reduces the frictional resistance between the ball and the table and avoids problems such as the ball sliding and getting stuck or the trajectory deviating due to differences in the flatness of the table and dust adhesion. Even after a long game, the airflow assistance can still maintain the consistency of the ball's movement, improve the player's control precision of the ball, and reduce game errors caused by equipment factors. The infrared sensors around the table can capture the ball's sliding motion in real time. Combined with the screen effects triggered by the updated components (such as trajectory light and shadow, collision animation), the linkage effect of "the ball moves and there is special effect feedback" is achieved.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] This utility model provides, for example Figure 1-5 The virtual scene simulator shown is used in interactive projection games and includes:

[0031] The machine base 1 has several supporting legs 2 connected to its bottom, which are used to support various functional components and provide a stable interactive operating platform.

[0032] The bracket 3 is located on one side of the machine base 1 and connected to the machine base 1. The bracket 3 is equipped with a projection component, which is used to project the game screen onto the machine base 1. The bracket 3 provides fixed support for the projection component and forms a wiring space inside to realize electrical connection between components.

[0033] The acquisition component is located inside the machine 1 and is used to acquire the game actions of the game participants in the game screen on the machine 1. The game actions include the actions of the game participants touching the projected screen on the machine 1 with their limbs. At the same time, the acquired action information is converted into electrical signals for transmission.

[0034] The positioning component is located inside the machine 1 and is used to receive signals transmitted by the acquisition component and obtain the coordinates corresponding to the game action. It can also process the coordinate data to meet the needs of subsequent screen updates.

[0035] An update component, located within the machine 1, is used to generate new game screen instructions based on the trigger action corresponding to the coordinates, and to control the projection component to project the updated game screen onto the machine 1.

[0036] The top of the machine 1 is equipped with a projection panel 4, which has high reflectivity and anti-interference characteristics. The projection component can clearly project the game screen onto the projection panel 4, and the projection panel 4, as an interactive operation surface, can withstand the physical touch of the game participants.

[0037] The projection component includes a projector 5, which is located inside the top of the bracket 3. The back of the bracket 3 is equipped with a first projection control motherboard 6 and a second projection control motherboard 7, both of which are electrically connected to the projector 5. The first projection control motherboard 6 and the second projection control motherboard 7 can realize redundant processing and coordinated control of the projection signal to ensure that the projector 5 stably outputs the game screen. At the same time, they can receive screen update instructions from the update component and drive the projector 5 to adjust the screen.

[0038] The positioning component includes a game motherboard 8, which is located inside the machine 1. The game motherboard 8 analyzes and processes the motion data transmitted by the acquisition component through a built-in algorithm, converts it into precise coordinates corresponding to the game screen, and can transmit the coordinate information to the update component in real time.

[0039] The update component includes a control module, which is integrated on the game motherboard 8. The control module is used to receive coordinate information transmitted by the positioning component, determine the trigger action corresponding to the coordinates according to the preset game logic and generate new screen data, and then send control commands to the projection component to control the projector 5 to project the updated game screen.

[0040] The machine 1 is equipped with a hockey mainboard 9, which is used to support the logic control of a specific hockey game. Both the hockey mainboard 9 and the game mainboard 8 are electrically connected to a power supply box 10 on one side, which provides a stable voltage to each mainboard. The game mainboard 8 is equipped with an amplifier board 11 and a power supply 12 on both sides. The amplifier board 11 is used to amplify the audio output of the game. One end of the power supply 12 is electrically connected to a power strip 13 inside the machine 1 through a plug. The power strip 13 is used to connect to an external power source and provide a power interface for each electrical component inside the device.

[0041] The machine platform 1 is equipped with a fan 14, the fan 14 can adjust its speed according to the operating temperature of the equipment. The projection plate 4 is evenly distributed with a number of air outlets 15. When the fan 14 is working, the air outlets 15 can form a uniform airflow to help the ball slide on the table and improve the smoothness of the slide. The frame around the table of the machine platform 1 is equipped with a number of infrared sensors 16. The infrared sensors 16 are electrically connected to the acquisition component to detect the sliding motion of the ball and transmit signals.

[0042] The bottom of the support leg 2 is rotatably connected to a caster wheel, which has a locking function, enabling flexible movement and stable fixation of the equipment.

[0043] This virtual scene simulator, used in interactive projection games, works by connecting power strip 13 to mains power. The power supply box 10 then regulates the external power in power strip 13, converting it into voltages suitable for each component, and then transmitting it through lines to the first projection control motherboard 6, the second projection control motherboard 7, the projector 5, and other electrical components to achieve power distribution. The first projection control motherboard 6 is responsible for generating the initial signal, encoding the preset game screen parameters, and transmitting them to the second projection control motherboard 7. The two motherboards ensure signal consistency through an internal collaborative verification mechanism, and then jointly send a start command to the projector 5. The optical engine component in the projector 5 receives the command and starts the light source. The lens module adjusts the focal length and projection angle according to the parameters transmitted from the projection control motherboard, and finally accurately projects the game screen onto the projection board 4 on top of the machine 1 to form the initial game scene.

[0044] The acquisition component includes an array of infrared emitters and infrared cameras, both mounted on bracket 3. When a player touches the projection board 4, the infrared emitters continuously emit infrared light into the area of ​​the projection board 4. The touch point reflects the infrared light, and the infrared camera captures the image of the light spot formed by the reflected light in real time. Its internal image sensor converts the light signal into an electrical signal, and then transmits the original image data to the positioning component via a data transmission line. Inside the positioning component's game motherboard 8, the processor receives the image data from the acquisition component and calls the built-in image recognition algorithm module. The algorithm module analyzes the shape and position of the light spot in the image, combining it with the preset coordinate mapping model of the projection board 4. The physical location of the light spot is converted into digital coordinate information. During the conversion process, the processor and algorithm module interact in real time through the internal bus to continuously correct the coordinate deviation and ensure positioning accuracy. The update component (control module) integrated on the game motherboard 8 receives the coordinate information through the internal interface and judges the interactive event corresponding to the coordinate (such as hitting the target, moving the character, etc.) according to the preset game logic. The control module generates the corresponding screen adjustment command and sends it to the signal receiving unit of the projector 5 through a dedicated line. The image processing chip in the projector 5 interprets the command and drives the optical engine component to adjust the light intensity and color. The lens module simultaneously fine-tunes the projection angle so that the screen on the projection board 4 is updated in real time and completes the interactive response to the participant's actions.

[0045] When the player presses the coin-insertion button on one side of machine 1 and inserts a coin, the button immediately sends a ball-dispensing command to the ball-dispensing mechanism and a start command to the fan 14. The ball-dispensing mechanism pushes the game ball to the center of the tabletop of machine 1. The fan 14 starts simultaneously and generates airflow. The airflow generated by the fan 14 passes through the air ducts inside the projection panel 4 and is evenly blown onto the tabletop through the evenly distributed air outlets 15. The airflow acts on the bottom of the ball to create an "air cushion effect," reducing friction between the ball and the projection panel 4, allowing the ball to slide smoothly after being pushed by the player, and preventing deviation of the sliding trajectory due to excessive friction. As the ball slides on the projection panel 4, it continuously blocks the four sides of the projection panel 4. The infrared sensor 16 inside the frame emits infrared light; the infrared sensor 16 transmits the detected "ball sliding signal" to the acquisition component in real time. The acquisition component performs preliminary processing on the signal and then transmits it to the positioning component. The game motherboard 8 of the positioning component generates the coordinates corresponding to the ball sliding trajectory based on the signal. The update component judges the ball's motion state, such as sliding direction, speed, and collision position, based on the coordinates, and triggers preset game screen effects, such as ball trajectory light and shadow following, explosion animation when colliding with the border, and flowing light effect when speed increases. Finally, the special effects screen is projected onto the projection board 4 through the projector 5, realizing the real-time linkage of "ball sliding - signal detection - screen effects".

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
