VR Shooting Game Recoil Simulation via Physics Engine

The patent replaces the animation-based simulation system with a physics-based system. Instead of using pre-defined animations to simulate recoil, the invention applies physical forces to the weapon holder through a physics engine, allowing the weapon to recoil according to actual physical laws. This substitution transforms the system from a visual illusion to a physically accurate simulation, resolving the contradiction between implementation simplicity and game realism.

The patent changes the fundamental parameter of recoil simulation from animation keyframes to physical force parameters. By introducing force magnitude, direction, and application timing as controllable parameters, the system can dynamically adjust recoil behavior to match real-world ballistics, thereby improving game realism while maintaining implementation feasibility through parameterized control.

The patent introduces dynamic physics-based recoil simulation that responds to shooting actions in real-time. Unlike static animation modes, the physics engine continuously calculates and applies recoil forces based on weapon properties, ammunition type, and shooting conditions. This dynamic approach maintains familiar interaction patterns while dramatically improving recoil simulation quality through physics-based responsiveness.

The patent introduces a physics engine as an intermediary between the player's shooting action and the weapon's recoil response. This intermediary layer processes the shooting input and translates it into physically accurate recoil forces, bridging the gap between simple button presses and complex physical reactions. The physics engine acts as a mediator that preserves interaction simplicity while enabling realistic recoil behavior.
