Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional controllers are used for game interaction, then the control method is simple and reliable, but user interactivity is limited and lacks advancement
Solution Approach 1:
The patent replaces traditional mechanical controllers with an optical-based interaction system. A video capture device captures images of pattern codes displayed on a screen, and a processor decodes these patterns to recognize user input. This substitutes mechanical controller hardware with optical detection and computational processing, enabling more versatile and adaptable interaction methods while reducing dependence on physical controller complexity.
2Adaptability or versatility
If pattern codes with light-reflective tags are used, then multiple pattern configurations can be decoded for enhanced interaction, but the detection and measuring difficulty increases
Solution Approach 1:
The patent employs light-reflective tags that change their optical properties when illuminated. These tags reflect light in specific patterns that can be captured by the video capture device. The pattern code's visual characteristics change based on light interaction, allowing multiple distinguishable configurations to be detected. This optical variation method enables enhanced pattern code functionality while providing clear visual signals for detection.
Solution Approach 2:
The system implements a feedback mechanism where the video capture device continuously monitors the pattern code's visual state, and the processor provides decoded information back to the game system. This closed-loop feedback enables reliable detection of pattern configurations by comparing expected patterns with captured images, resolving the detection complexity through systematic verification and recognition algorithms.
3Adaptability or versatility
If light-reflective surfaces are added to tags, then the pattern code can define different characteristics based on light application, but the manufacturing complexity increases
Solution Approach 1:
The patent utilizes changes in optical parameters of the pattern code tags. By applying light to light-reflective surfaces on the tags, the pattern code transitions between different visual states (e.g., reflective vs. non-reflective appearances). This parameter change approach allows a single physical tag to represent multiple states, enabling pattern code state variability without requiring multiple different physical components, thus maintaining manufacturing simplicity.

AI summary
A method, a system and an article of manufacture are provided to generally enable computer interactivity for any type of application. The method is also capable of providing interacting functionality with a computer game. The method includes presenting a pattern code defined by at least two tags. Applying a light toward the pattern code at a specific time. Then, the method moves to capturing a first video frame of the pattern code before the light is applied to the pattern code, such that the first video frame defines a first characteristic of the pattern code. A second video frame is then captured for the pattern code when the light is applied to the pattern code, such that the second video frame defines a second characteristic of the pattern code. The method then enables decoding of the first characteristic and the second characteristic of the pattern code to produce decoded information.
