AR VR Controller Reel Mechanism for Force Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality (AR) and virtual reality (VR) controllers fail to provide realistic and immersive experiences due to limited simulation of forces, lacking adequate tools to make AR/VR experiences sufficiently realistic and immersive.
Innovation Solution
A controller system with a housing, wrist strap, and reels that can move relative to the wrist strap, powered by a motor and battery, and controlled by a processor with wireless transceiver, allowing for simulation of forces through reel rotation, mimicking actions like recoil or pushing, to enhance the realism of AR/VR interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If vibration motors are used to simulate force in AR/VR controllers, then the controller can provide some force feedback, but the simulation of force is limited and not sufficiently realistic
Solution Approach 1:
The patent replaces traditional vibration motors with reel mechanisms that use lines to physically pull and push the controller housing. This mechanical substitution allows for more realistic force simulation by directly applying mechanical forces through the reel and line system, enabling actions like recoil, pushing, and pulling that better mimic real-world physical interactions in AR/VR environments
Solution Approach 2:
The reel mechanisms are designed to be dynamically controllable, allowing the controller to simulate varying forces in different directions. The reels can rotate to wind or unwind lines, creating dynamic push and pull forces that adapt to the virtual scenario, enhancing the versatility and realism of force feedback beyond static vibration
2Force
If reels and lines are added to the controller to simulate force, then force simulation capability is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the reel mechanisms within the controller housing, merging the force simulation components into a compact unified structure. The reels are positioned inside the housing with lines extending to external anchor points, combining multiple functions (motor, reel, line management) into an integrated assembly that maintains structural coherence while enabling complex force simulation
Solution Approach 2:
The line acts as an intermediary element between the reel mechanism and the external environment (wrist strap or anchor points). This intermediary allows the internal reel to transmit forces externally without requiring direct mechanical connection to external components, simplifying the overall structure while maintaining force simulation capability

AI summary
In one aspect, a controller for engaging with augmented reality (AR) content and/or virtual reality (VR) content includes a housing and a wrist strap engageable with the housing. The controller also includes at least one reel engageable with the housing and the wrist strap to move the housing relative to the wrist strap while the wrist strap is worn by a person to simulate force indicated in the AR or VR content.
