Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive gaming systems face challenges in providing a seamless and immersive physical-virtual experience due to difficulties in accurately detecting gamer gestures and maintaining consistent game interactions across different modes and environments, particularly when using diverse articles and varying lighting conditions.
Innovation Solution
The use of engineered light sources emitting narrow frequency bands in combination with surface coatings, such as nanoparticles, dyes, and electrochromic polymers, to dynamically alter surface color and improve gesture detection, along with a generalized 6 DoF gesture input algorithm and cross-article dataset processing, enhances gamer interaction and perception across different game modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional broad-spectrum lighting is used, then the environment appears natural to observers, but gesture detection and article tracking precision deteriorates due to lack of spectral differentiation
Solution Approach 1:
The patent segments the broad-spectrum light into multiple narrow frequency bands using engineered light sources. Each frequency band is used for specific detection purposes (e.g., tracking different articles or detecting different gestures), enabling precise measurement while maintaining overall lighting quality through composite illumination.
Solution Approach 2:
The system dynamically changes the spectral parameters of illumination by switching between different narrow frequency bands. This allows optimization of detection precision for specific articles or gestures while maintaining natural appearance through appropriate band selection and combination.
2Adaptability or versatility
If multiple articles with similar appearances are used in the game, then player engagement and game variety improve, but detection and tracking of individual articles deteriorates due to visual similarity
Solution Approach 1:
The patent applies local quality by giving each article a unique spectral reflection signature through specialized coatings. While articles appear similar visually, their local spectral properties differ, enabling precise identification and tracking of individual articles through frequency-selective detection.
Solution Approach 2:
The system uses spectral color differentiation rather than visible color changes. Each article reflects specific narrow frequency bands differently, creating unique spectral fingerprints that enable accurate tracking while maintaining visual consistency for players.
3Adaptability or versatility
If dynamic lighting conditions change during gameplay, then environmental realism improves, but consistency of game interactions and detection reliability deteriorates
Solution Approach 1:
The system uses periodic modulation of narrow frequency band illumination to maintain detection consistency. By modulating at specific frequencies and detecting corresponding responses, the system can distinguish game-related optical changes from environmental lighting variations, ensuring reliable detection throughout gameplay.
Solution Approach 2:
The engineered light sources and detection system serve multiple functions: they provide environmental illumination, enable article tracking, detect gestures, and maintain game state consistency simultaneously. This multi-functionality ensures reliable detection across varying lighting conditions while maintaining environmental realism.
4Loss of information
If traditional displays are used that are always visible, then information accessibility improves, but immersion and secrecy of game elements deteriorates due to constant visibility
Solution Approach 1:
The patent implements dynamic displays using electrochromic materials that can transition between transparent and opaque states. Game information is displayed only when needed or when players are properly authenticated, providing both accessibility and immersion by controlling visibility dynamically based on game state.
Solution Approach 2:
The display system changes its optical parameters (transparency, opacity, color) in response to game events, player actions, or authentication status. This allows information to be accessible when needed while maintaining secrecy and immersion during other game phases.

AI summary
A gaming system comprising at least one transparent display where at least two gamers are standing on opposite sides of the display. The first gamer is wearing a first pair of filtering glasses that limit the first gamer to seeing only a first stream A of images comprising video being emitted by the transparent display. The second gamer is wearing a second pair of filtering glasses that limit the second gamer to seeing only a second stream B of images comprising the emitted video. Each gamer perceives different augmentations of the opposing player as the game is operated causing the video comprising the A and B streams. The system further comprises an additional display functioning like the first display but separated to form an interior corridor, where a projector is running on rails within the corridor to create a movable ghost image via a pepper's mill apparatus.
