Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gaming technologies lack immersive and intuitive control mechanisms, especially when using head-mounted displays (HMDs), as users cannot see their hands or objects they are holding, limiting the sense of presence and interaction in virtual environments.
Innovation Solution
Development of gloves with integrated magnetic and fluid-based haptic feedback systems that simulate the feeling of grasping, manipulating, and interacting with virtual objects, allowing for synchronized feedback with the virtual environment, including magnetic actuators, fluid channels, and sensors to replicate tactile sensations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If head-mounted displays are used to provide immersive visual experience, then the sense of presence in virtual environment is improved, but the user cannot see their hands or objects they are holding which limits interaction
Solution Approach 1:
The patent introduces haptic feedback gloves as an intermediary device that provides tactile information about virtual objects and hand positions, compensating for the lack of visual feedback in HMD environments. The gloves include force feedback actuators, vibration motors, and pressure sensors that serve as mediators between the user and the virtual environment.
Solution Approach 2:
The system implements closed-loop feedback by using sensors in the gloves to detect hand movements and forces, transmitting this data to the virtual environment, and providing haptic feedback based on virtual object interactions. This creates a feedback cycle that enhances presence without requiring visual visibility of hands.
2Ease of operation
If conventional controllers are used for interaction, then the system is simple to operate, but the interaction lacks immersion and intuitiveness
Solution Approach 1:
The patent replaces conventional mechanical controllers with haptic feedback gloves that use electromagnetic actuators, piezoelectric elements, and magnetic fields to provide force feedback. This substitution maintains ease of operation through natural hand movements while dramatically improving immersion through tactile feedback.
Solution Approach 2:
The system changes the operational parameters from visual-manual control to tactile-force control. The gloves utilize variable stiffness materials, adjustable magnetic field strengths, and dynamic vibration frequencies to provide intuitive interaction that feels natural while highly immersive.
3Ease of operation
If haptic feedback mechanisms are added to gloves, then the tactile sensation is improved, but the device complexity increases
Solution Approach 1:
The patent divides the haptic feedback system into segmented independent units distributed across different fingers and palm areas. Each segment can be controlled independently, allowing complex tactile patterns to be created through simple modular components rather than a single complex mechanism.
Solution Approach 2:
The haptic feedback components serve multiple functions: force feedback actuators provide both resistance and vibration, magnetic elements provide both attraction/repulsion and positional sensing, and the glove structure itself serves as both the interface and the feedback medium. This multi-functionality reduces overall system complexity.
