With the continuous development of social productivity and science and technology, the demand for VR technology across various industries is increasingly strong. VR technology has also made significant progress and is gradually becoming a new field of scientific and technological research.

[0003] With the advancement of technology, VR has entered the lives of ordinary people, and people's interest in VR is growing stronger. As a result, many VR experience centers have emerged, where people can use VR devices to experience virtual environments, such as games and sports. However, most existing VR experiences only allow one user at a time. This is because when many people use VR devices simultaneously, the virtual environment differs from the real environment. While immersed in the virtual environment, there is a high risk of bumping into other users wearing VR devices. This makes single-person VR experiences inefficient, and multi-person VR experiences pose a collision hazard. Summary of the Invention

Attached Figure Description

[0049] Figure 1 This is a flowchart illustrating a multi-user VR experience anti-collision control method according to a specific embodiment of the present invention;

[0050] Figure 2 This is a schematic diagram of the structure of a multi-user VR experience anti-collision control device provided in a specific embodiment of the present invention. Detailed Implementation

[0051] This invention discloses a collision avoidance control method for multi-user VR experiences. Those skilled in the art can refer to this document and appropriately modify the technical details for implementation. It is particularly important to note that all similar substitutions and modifications are obvious to those skilled in the art and are considered to be included in this invention. The methods and applications of this invention have been described through preferred embodiments. Those skilled in the art can clearly modify or appropriately change and combine the methods and applications described herein without departing from the content, spirit, and scope of this invention to implement and apply the technology of this invention.

[0052] The applicant's research revealed that when many people simultaneously use VR devices, the virtual environment differs from the real environment. Immersed in the virtual environment, users may struggle to notice other VR users approaching, increasing the likelihood of collisions. Furthermore, if the paths of multiple VR devices are altered simultaneously due to a lack of unified management and scheduling among them, collisions are highly probable. Moreover, altering all paths is inefficient and disrupts the user's VR experience.

[0053] Therefore, embodiments of the present invention provide a collision avoidance control method for multi-user VR experiences, such as... Figure 1 As shown, the method includes:

[0054] Step S101: Communicate with each VR device to obtain the current location of each VR device in real time.

[0055] Each VR device is worn by a different user. The VR devices are wireless head-mounted devices.

[0056] Optionally, communicate with each VR device to obtain the current location of each VR device in real time, including:

[0057] The position sensor installed in the VR device is controlled to perform real-time position measurement, thereby obtaining the position of the VR device;

[0058] It requests the current location from the VR device in real time and receives the current location information sent by the VR device.

[0059] It should be noted that the position sensor determines the location of the VR device by measuring the distance between the VR device and various landmarks in the VR experience area.

[0060] Step S102: In response to any two VR devices approaching each other and reaching a collision danger distance, collect the motion state of the VR devices within the collision danger distance.

[0061] The collision danger distance is determined based on the user's collision reaction time, and the motion status includes motion speed and motion direction.

[0062] It should be noted that the collision danger distance refers to the dangerous distance at which two VR device wearers may collide. It is determined based on the user's collision reaction time. If the collision danger distance is too short, the user will not be able to react in time to change their path.

[0063] In this embodiment of the invention, the path change scheduling of VR devices is performed in pairs, preventing missed or false detections. For example, device 1 can be matched with device 2, and device 1 can also be matched with device 3 simultaneously.

[0064] Step S103: Compare the movement speed of VR devices within the collision danger distance to obtain slow-motion VR devices.

[0065] Among them, slow-motion VR devices are VR devices that move slowly within the collision danger distance.

[0066] The slow-motion VR device provided in this invention aims to avoid collisions by altering its movement path. Slow speed means it's easier to change the speed and direction of movement. If the speed is too high, it's difficult to adjust the direction, and even if a change in path is known, the inability to adjust the direction in time can lead to a collision.

[0067] Step S104: Generate obstacle avoidance routes for slow-moving VR devices based on the motion status of VR devices within the collision danger distance.

[0068] Optionally, based on the motion state of the VR device within the collision danger distance, an obstacle avoidance route is generated for the slow-moving VR device; including:

[0069] The collision location is determined based on the speed and direction of movement of the VR device within the collision danger distance;

[0070] Based on the collision location and the movement direction of the slow-motion VR device, an obstacle avoidance route is generated; wherein, the obstacle avoidance route is the path generated by the slow-motion VR device with the minimum change of direction to avoid the collision location.

[0071] It should be noted that obstacle avoidance routes with minimal detours can ensure a good user experience and prevent the experience from deteriorating due to sudden and drastic route changes.

[0072] Step S105: Based on the obstacle avoidance route, generate obstacles corresponding to the obstacle avoidance route in the next frame image of the slow motion VR device.

[0073] It's important to note that in the next frame of the slow-motion VR device, obstacles corresponding to the obstacle avoidance route are generated, allowing the user to avoid obstacles and move along the avoidance route. This ensures that the user's experience isn't disrupted by sudden direction-changing prompts, keeping the user fully immersed.

[0074] Step S106: Send the next frame image to the slow motion VR device so that the user of the slow motion VR device can avoid obstacles and move along the obstacle avoidance route.

[0075] In this invention, there is more than one obstacle avoidance route, and the obstacles are not identical to other VR devices within the collision danger distance. By avoiding obstacles, collisions can be avoided, allowing movement along an obstacle avoidance route.

[0076] The embodiments of the present invention only change the movement path of a number of VR devices to avoid collisions, thus ensuring the experience of most users.

[0077] Optionally, the method further includes:

[0078] Control each VR device to detect fixed obstacles within a preset range centered on itself, and accept the inspection results;

[0079] In response to the appearance of a fixed obstacle within a preset range, and taking into account whether other VR devices are present within the collision danger distance, a fixed obstacle avoidance route is generated;

[0080] Based on the fixed obstacle avoidance route, a warning signal is sent to VR devices that encounter fixed obstacles within a preset range.

[0081] It should be noted that this embodiment of the invention also includes fixed obstacle detection, and, combined with the possibility of collisions between users, simultaneously avoids collisions between users and fixed obstacles, thus protecting user safety. Furthermore, the alert method in this embodiment can be the same as the alert method for user collisions, both employing obstacle generation methods.

[0082] Optionally, the method further includes:

[0083] The entire VR experience venue is divided into multiple activity areas of pre-set size;

[0084] Based on the current location of each VR device, the user density of each activity area is obtained;

[0085] In response to the user density in the activity area exceeding a preset value, a guidance path is generated and sent to the VR device, allowing some users to leave the saturated activity area according to the guidance path.

[0086] It should be noted that this invention uses density detection for user scheduling to ensure that the number of VR users in each activity area does not exceed a threshold. This reduces the occurrence of collisions and also maintains a better user experience.

[0087] Based on the disclosed anti-collision control method for multi-user VR experiences, this invention provides an anti-collision control device for multi-user VR experiences. This device wirelessly connects to multiple VR devices, such as... Figure 2 As shown, the device includes: a current position acquisition module 201, a motion state acquisition module 202, a slow motion VR device acquisition module 203, a path generation module 204, an obstacle generation module 205, and an image transmission module 206.

[0089] The motion state acquisition module 202 is used to acquire the motion state of the VR devices within the collision danger distance in response to any two VR devices approaching each other and reaching the collision danger distance; wherein, the collision danger distance is determined according to the user's collision reaction time, and the motion state includes motion speed and motion direction.

[0090] The slow-motion VR device acquisition module 203 is used to compare the movement speed of VR devices within the collision danger distance to obtain slow-motion VR devices; wherein, the slow-motion VR device is a VR device that moves relatively slowly within the collision danger distance;

[0091] The path generation module 204 is used to generate obstacle avoidance routes for slow-moving VR devices based on the motion state of the VR devices within the collision danger distance.

[0092] The obstacle generation module 205 is used to generate obstacles corresponding to the obstacle avoidance route in the next frame image of the slow motion VR device based on the obstacle avoidance route.

[0093] The image sending module 206 is used to send the next frame image to the slow motion VR device so that the user of the slow motion VR device can avoid obstacles and move along the obstacle avoidance route.

[0094] Optionally, the current location acquisition module 201 includes: a measurement control submodule and a location request acquisition submodule;

[0095] The measurement and control submodule is used to control the position sensors installed in the VR device to perform real-time position measurement, thereby obtaining the position of the VR device;

[0096] The location request submodule is used to request the current location from the VR device in real time and to receive the current location information sent by the VR device.

[0097] Optionally, the path generation module 204 includes: a collision location point acquisition submodule and an obstacle avoidance route generation submodule;

[0098] The collision location acquisition submodule is used to obtain the collision location based on the speed and direction of movement of the VR device within the collision danger distance;

[0099] The obstacle avoidance route generation submodule is used to generate an obstacle avoidance route based on the collision location and the movement direction of the slow-motion VR device; wherein, the obstacle avoidance route is the path generated by the slow-motion VR device with the minimum change of direction to avoid the collision location.

[0100] Optionally, the device may also include: a fixed obstacle detection and control module, a fixed obstacle route generation module, and an alert signal sending module;

[0101] The fixed obstacle detection and control module is used to control each VR device to detect fixed obstacles within a preset range centered on itself, and to receive the inspection results;

[0102] The fixed obstacle route generation module is used to generate a fixed obstacle avoidance route in response to the appearance of a fixed obstacle within a preset range, combined with whether other VR devices are present within the collision danger distance.

[0103] The reminder signal sending module is used to send reminder signals to VR devices that encounter fixed obstacles within a preset range, based on the fixed obstacle avoidance route.

[0104] Optionally, the device may also include: an activity area division module, a user density acquisition module, and a user guidance module;

[0105] The activity area division module is used to divide the entire VR experience venue into multiple activity areas of preset size;

[0106] The user density acquisition module obtains the user density of each activity area based on the current location of each VR device;

[0107] The user guidance module, in response to the user density in the activity area exceeding a preset value, generates a guidance path and sends it to the VR device, allowing some users to leave the saturated activity area according to the guidance path.

[0108] This invention communicates with each VR device to obtain their current position in real time. In response to any two VR devices approaching each other and reaching a collision danger distance, the motion state of the VR devices within that distance is collected. The motion speeds of the VR devices within the collision danger distance are compared to identify the slow-moving VR device. Based on the obstacle avoidance route, obstacles corresponding to the obstacle avoidance route are generated in the next frame of the slow-moving VR device. The next frame is sent to the slow-moving VR device so that its user can avoid obstacles and move along the avoidance route. This invention establishes communication with each VR device and performs unified planning and scheduling, ensuring that multiple users can experience VR while avoiding collisions. This invention compares close VR devices and determines one to change its path to avoid collision. Compared to changing the path of every VR device, this invention maximizes the protection of the VR experience for most users. Changing the path of the slower VR device is to prevent collisions caused by users of faster VR devices struggling to adjust their paths. This invention generates obstacles in VR images to alter the user's movement path, thus avoiding abrupt collision warnings and ensuring a positive user experience. It also detects fixed obstacles to prevent their impact on the VR experience. Furthermore, it uses user density detection to ensure the number of users in each activity area does not exceed a threshold, reducing collisions and improving user experience. In summary, this invention reduces collisions for a few users while allowing most users to participate in VR activities according to their own wishes, even with multiple users participating.
