XR Firearm Controller Integration for Realistic Combat Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional VR-based combat training systems fail to provide realistic training using real firearms and often require separate equipment like head-mounted displays, limiting immersion and practicality.
Innovation Solution
A method and system for XR-based ultra-realistic combat training using a real firearm with an XR controller, where the XR controller is attached to the firearm, and the training difficulty is adjusted based on the aiming position, incorporating sensors and projectors to project XR content and detect interactions like trigger pulls and magazine replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional VR-based combat training systems are used, then virtual training content can be provided, but realistic training using real firearms cannot be achieved
Solution Approach 1:
The patent merges the real firearm with the XR controller to create a unified training system. The XR controller is attached to the real firearm, combining physical weapon handling with virtual reality training content, allowing trainees to use real firearms while participating in virtual combat scenarios.
Solution Approach 2:
The XR controller serves multiple functions: it acts as both a control device for the VR environment and an attachment for the real firearm. This multi-functional design eliminates the need for separate equipment, allowing the same device to enable both virtual interaction and physical weapon operation during training.
2Ease of operation
If head-mounted display (HMD) is used for VR training, then virtual content can be displayed, but immersion is reduced and separate equipment is required
Solution Approach 1:
The patent extracts the HMD requirement from the training system by using XR technology that projects content through the real firearm's sights or attached displays, eliminating the need for separate head-mounted equipment while maintaining virtual training capabilities.
Solution Approach 2:
The XR controller is merged with the real firearm, creating an integrated system where the firearm itself becomes part of the XR interface. This integration eliminates the need for separate HMD equipment, making the training system more accessible and reducing overall device complexity.
3Adaptability or versatility
If XR content is projected onto XR environment, then immersive training is achieved, but system complexity increases
Solution Approach 1:
The XR controller serves as a multi-functional component that integrates sensing, control, and display functions. By embedding these functions in a single device attached to the firearm, the system reduces overall complexity while maintaining the ability to project immersive XR content onto the training environment.

AI summary
Disclosed is a method for extended reality (XR)-based ultra-realistic combat training using a real firearm with an XR controller. The method comprises: transmitting XR content from a service providing server to a splitter of an XR environment, and transmitting the XR content from the splitter to projectors of the XR environment so that a plurality of projectors project the XR content onto the XR environment; detecting, by sensors of the XR environment, positions of a plurality of XR controller and transmitting the detected positions to the service providing server; receiving, by the service providing server, interactions between the XR controller and the real firearm from the plurality of XR controller; correcting, by the service providing server, the XR content according to the interactions between the XR controller and the real firearm and the positions of the XR controller, and transmitting the corrected XR content to the splitter of the XR environment; and transmitting the corrected XR content from the splitter to the projectors and projecting the corrected XR content onto the XR environment by the plurality of projectors. The interactions between the XR controller and the real firearm include at least one recognized by the XR controller of whether a trigger of the real firearm with the XR controller attached is pulled, and whether a magazine is replaced.
