Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If haptic media signals are stored and processed as a single data unit, then storage simplicity is maintained, but processing flexibility deteriorates
Solution Approach 1:
The patent segments haptic media signals into multiple independent haptic channels, each representing different spatial positions or haptic properties. This segmentation allows flexible processing of individual channels while maintaining overall signal integrity, resolving the contradiction between processing flexibility and data structure complexity.
Solution Approach 2:
The patent introduces a channel dimension to the haptic data structure, transforming a single-dimensional signal into a multi-dimensional structure with channels. This dimensional expansion enables independent processing of each channel while preserving the ability to reconstruct the complete haptic experience, thereby improving processing flexibility without excessive complexity.
2Productivity
If haptic channels are mixed and processed separately, then processing flexibility is improved, but computational complexity increases
Solution Approach 1:
By segmenting the haptic signal into distinct channels corresponding to different spatial positions or haptic properties, the system can process each channel independently and in parallel. This segmentation improves processing efficiency while keeping computational complexity manageable through modular processing units.
Solution Approach 2:
The patent merges multiple processed haptic channels back into a unified haptic output after independent processing. This merging approach allows the system to benefit from parallel processing of individual channels while delivering a cohesive haptic experience, thereby improving productivity without excessive computational overhead.
Data Source
AI summary
In a haptic media processing method, an interchange-format file of haptic media content is obtained. The interchange-format file includes a data structure of a haptic channel. The data structure of the haptic channel includes a channel group flag, and the channel group flag indicates whether the haptic channel belongs to a channel group. When the channel group flag indicates that at least two haptic channels belong to the channel group. The haptic channels in the channel group are mixed, to obtain a haptic media signal. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.
