Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional encoding/decoding technology is used for haptics media, then the basic haptics content can be presented, but reusable haptics media cannot be properly encapsulated and transmitted, resulting in poor presentation effect
Solution Approach 1:
The haptics media is segmented into reusable and non-reusable portions through the reusable_flag parameter. The encoding process separates haptics samples that can be reused across different time points from those that cannot, allowing the decoder to efficiently handle only the necessary portions while maintaining proper presentation effect.
Solution Approach 2:
The encoding process performs preliminary action by setting the reusable_flag and presentation_timestamp during encoding. This pre-marking of reusable content allows the decoding process to efficiently identify and reuse haptics samples without requiring complex real-time analysis, thereby improving presentation effect while maintaining adaptability.
2Reliability
If haptics media is encoded without presentation indication information, then the encoding process is simpler, but the decoder cannot accurately present reusable haptics media
Solution Approach 1:
The reusable_flag and presentation_timestamp act as intermediary elements that bridge the encoder and decoder. These metadata parameters carry the necessary information about reusability without requiring complex communication protocols or additional processing steps, thus improving accurate presentation while keeping the encoding process relatively simple.
Solution Approach 2:
The presentation indication information is copied into the bitstream as metadata alongside the haptics samples. This copying mechanism allows the decoder to access reusability information without requiring the encoder to perform complex real-time calculations or transformations during the encoding process.
3Reliability
If all haptics content is treated as non-reusable, then the encoding process is straightforward, but the presentation effect of reusable haptics media deteriorates
Solution Approach 1:
The encoding process dynamically determines the reusable_flag value for each haptics sample based on its characteristics and potential for reuse. This dynamic approach allows the system to automatically identify reusable content without requiring manual configuration or complex pre-processing, thereby improving presentation effect while maintaining encoding simplicity.
Solution Approach 2:
The haptics media encoding system performs self-service by automatically analyzing haptics samples and setting the reusable_flag without external intervention. The system identifies which samples can be reused based on their inherent properties, eliminating the need for complex external processing or manual configuration while improving presentation effect.
