Innovation Solution
A method and apparatus for generating tactile signals that obtain target scene tactile information and a basic frequency band tactile signal set, allowing for the creation of diverse tactile sensations by combining basic frequency band tactile signals based on specific scene categories and sensations, reducing reliance on pre-stored sensations and minimizing storage requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If preset tactile effects are used in games, then the implementation is simple, but the tactile diversity is limited and cannot satisfy diverse tactile needs
Solution Approach 1:
The patent segments tactile signals into multiple frequency bands (low frequency band, middle frequency band, high frequency band) with different amplitude characteristics. By combining different frequency band signals in various proportions, diverse tactile effects can be generated from a limited set of basic signals, thus achieving tactile diversity without storing numerous complete tactile effect files.
Solution Approach 2:
The patent creates a universal tactile signal generation system where a small set of basic frequency band signals can serve multiple purposes. These basic signals can be combined in different ways to produce various tactile effects suitable for different game scenarios, making the system adaptable to diverse tactile needs while maintaining implementation simplicity.
2Adaptability or versatility
If more pre-stored tactile sensations are stored to provide diverse tactile effects, then the tactile diversity increases, but the storage space requirements increase
Solution Approach 1:
The patent decomposes complete tactile effect files into fundamental frequency band components (low, middle, high frequency bands). Instead of storing numerous complete tactile effect files, the system stores only these basic frequency band signals which can be recombined to generate diverse tactile effects, significantly reducing storage space while maintaining tactile diversity.
Solution Approach 2:
The patent achieves tactile diversity by changing the parameters (amplitude ratios, frequency band combinations) of basic frequency band signals rather than storing different complete tactile effect files. By adjusting the amplitude relationships between different frequency bands, various tactile sensations can be generated from the same basic signal set, reducing storage requirements.
