VR Physical Target Training for Real-World Skill Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual reality systems are ineffective in training users for real-world physical activities as they develop skills limited to the virtual environment and can teach improper techniques for real-life activities.
Innovation Solution
A virtual reality system that uses input devices and display devices to simulate physical targets with simulated physical properties, allowing users to practice proper form and exertion through interactive virtual targets that move relative to each other based on physical characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional virtual reality systems are used for training, then user immersion and enjoyment are improved, but skill transfer to real-world activities deteriorates
Solution Approach 1:
The system creates virtual copies of real-world objects (boxing gloves, punching bags, training equipment) with accurate physical properties and behaviors. These virtual copies replicate the mass, elasticity, resistance, and movement characteristics of real equipment, allowing users to practice skills that directly transfer to real-world applications while maintaining full virtual reality immersion
Solution Approach 2:
The system dynamically adjusts physical parameters of virtual objects (mass, elasticity, friction, resistance) to match real-world counterparts. By changing these parameters to reflect actual physical conditions, the training experience maintains realism while preventing the development of improper techniques that would not work in real-life scenarios
2Device complexity
If virtual targets without physical properties are used, then device complexity is reduced, but training effectiveness for real-world activities deteriorates
Solution Approach 1:
The system replaces complex mechanical training equipment with virtual representations that use software-based physics simulations. Instead of requiring physical punching bags, heavy bags, and various training apparatus, the system uses virtual models with programmed physical properties (mass, elasticity, friction) that replicate real equipment behavior through computational physics rather than physical mechanisms
3Ease of operation
If static virtual targets are used, then ease of operation is improved, but skill development for dynamic real-world activities deteriorates
Solution Approach 1:
The system transforms static virtual targets into dynamic objects that move, react, and respond based on physical principles. Virtual punching bags swing and bounce, targets move away from strikes, and equipment responds to user input with realistic physics-based animations. This dynamic behavior mirrors real-world training equipment, enabling users to develop adaptive skills for actual physical activities

AI summary
A system for training a user to perform a physical activity includes a control device that obtains movement information associated with a portion of a user's body and provides image information to a display device that displays an image associated with the portion of the user's body with a second image associated with a first target that is associated with physics information associated with simulated physical characteristics of the first target and a third image associated with a second target. The control device controls movement of the first image relative to the second image and the second image relative to the third image based on the movement information and the physics information.
