VR Controller Cage with Illumination Sources for Hand Motion Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gaming controllers lack the ability to track and simulate the actual motion of a user's hand movements, resulting in a less immersive virtual reality experience.
Innovation Solution
A hand-held controller with a user-input surface, grip, and a cage featuring illumination sources, such as LEDs, that can be detected by an image capturing device to model the user's hand motions, enhancing the virtual reality experience by translating hand movements into corresponding actions within the virtual environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional gaming controllers with buttons or knobs are used, then the controller structure is simple and easy to manufacture, but the controller cannot track or simulate actual hand motions, reducing virtual reality immersion
Solution Approach 1:
The patent applies illumination sources (LEDs) that emit light in different colors or patterns to enable motion tracking. The illumination sources create visible or detectable light patterns on the controller surface that allow the system to track hand motions, transforming the controller from a static input device to a dynamic tracking device that enhances virtual reality immersion
Solution Approach 2:
The patent introduces an intermediary tracking system consisting of illumination sources and detection mechanisms. This intermediary layer between the user's hand and the virtual environment enables motion capture and translation of physical movements into virtual actions, solving the immersion problem without requiring direct complex integration into the controller structure
2Measurement precision
If illumination sources are added to enable motion tracking, then hand motions can be detected and simulated, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent segments the controller into distinct functional modules: the illumination source array, the detection system, and the control electronics. This segmentation allows each component to be optimized and manufactured separately, then assembled into the complete tracking controller, reducing overall manufacturing complexity while enabling precise hand motion detection
Solution Approach 2:
The illumination sources serve multiple functions: they provide visual feedback to the user, enable motion tracking through light pattern detection, and can indicate controller status or selection states. This multi-functionality reduces the need for separate components, simplifying manufacturing while achieving precise motion detection capabilities
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for the detection and simulation of hand motions, providing a more immersive gaming experience by enabling the virtual environment to respond to actual user movements, thereby enhancing user engagement and realism.
Implementation Method 1
The cage includes a plurality of illumination sources on an outer surface of the cage. In some embodiments, the plurality of illumination sources includes a plurality of light-emitting diodes (LEDs).
Data Source
AI summary
A hand-held controller includes a user-input surface, a grip coupled to the user-input surface, and a cage coupled to the user-input surface at two points without the grip interposed between the user-input surface and the cage. The hand-held controller includes may further include a plurality of illumination sources on an outer surface of the cage.
