Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control information is transmitted through communication to control haptic presentation, then flexibility and remote control capability are improved, but communication delays cause timing deviations that impair user experience
Solution Approach 1:
The patent extracts only the essential frequency components from the control information signal. By identifying and removing redundant frequency components that do not contribute significantly to haptic perception, the data transmission time is reduced, thereby minimizing timing deviations caused by communication delays while maintaining the core haptic presentation functionality.
Solution Approach 2:
The patent changes the parameter of the control signal by filtering its frequency components. It identifies and retains only those frequency components that are most effective for haptic perception, transforming the original signal into a optimized version that transmits faster through communication channels while preserving the essential haptic effect.
2Measurement precision
If all frequency components are transmitted for accurate haptic control, then haptic presentation accuracy is improved, but transmission time increases causing delays
Solution Approach 1:
The patent extracts and transmits only the essential frequency components from the control information. By analyzing the frequency spectrum and identifying which components are most critical for haptic perception, it removes redundant components, thereby reducing transmission time while maintaining sufficient control accuracy for effective haptic presentation.
Solution Approach 2:
The patent applies partial action by transmitting only a subset of frequency components rather than the complete spectrum. This selective transmission includes the most important frequency components needed for haptic perception, achieving adequate control accuracy with reduced data volume and shorter transmission time.
3Speed
If communication data volume is reduced to minimize delay, then transmission speed is improved, but haptic stimulus quality may deteriorate
Solution Approach 1:
The patent changes the frequency domain parameters of the control signal by selectively filtering components. It transforms the signal to include only those frequency ranges that are most effective for haptic perception, achieving efficient compression that maintains stimulus quality while reducing data volume and increasing transmission speed.
Solution Approach 2:
The patent applies different quality requirements to different frequency components. Instead of uniformly compressing all frequency data, it identifies and preserves the frequency components that are most critical for haptic perception, allowing higher fidelity for important components while reducing or eliminating redundant components, thereby maintaining overall stimulus quality with reduced data volume.

AI summary
There is provided an information processing apparatus including a signal processor that extracts at least some frequency components as second control information from a plurality of frequency components included in first control information in accordance with a state of communication, in which a haptic presentation section that presents a haptic stimulus is controlled through the communication on the basis of the second control information.
