Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tactile stimulus technologies face challenges in flexibility due to changes in the position or installation layout of tactile-sense applying units, leading to inconsistent perceptual effects during recording and reproduction.
Innovation Solution
An information processing apparatus and method that acquires positional information of tactile-sense applying units and adjusts the tactile control signal accordingly, ensuring flexible application of tactile stimuli regardless of unit position changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the tactile control signal is generated for a specific actuator position during recording, then the tactile stimulus can be applied accurately at that position, but the system becomes inflexible when the actuator position changes during reproduction
Solution Approach 1:
The system dynamically adjusts the tactile control signal based on the actual actuator position detected during reproduction. The audio processing unit modifies the control signal in real-time according to position information, making the system adaptable to position changes while maintaining stimulus accuracy.
Solution Approach 2:
The system changes the parameters of the tactile control signal (such as timing, intensity, or frequency) based on the detected actuator position. By adjusting these parameters according to position information, the system maintains accurate tactile stimulus delivery even when the actuator position differs from the recording position.
2Adaptability or versatility
If the installation layout of tactile-sense applying units is changed, then the system can be adapted to different configurations, but the tactile stimulus perception becomes inconsistent between recording and reproduction
Solution Approach 1:
The system incorporates feedback by detecting the actual actuator position during reproduction and using this information to adjust the tactile control signal. This closed-loop approach ensures that the tactile stimulus remains consistent with the original recording intent, regardless of installation layout changes.
Solution Approach 2:
The system performs preliminary position detection and signal adjustment before applying the tactile stimulus. By preparing the corrected control signal based on detected position information in advance, the system ensures consistent tactile stimulus perception without requiring re-recording.
3Ease of operation
If the attachment state of the apparatus changes (e.g., attachment misalignment), then the system can accommodate different usage conditions, but the position of the tactile-sense applying unit becomes different from the recording position
Solution Approach 1:
The system dynamically compensates for attachment misalignment by detecting the actual actuator position and adjusting the tactile control signal in real-time. This allows the system to maintain position accuracy despite changes in attachment state or usage conditions.

AI summary
There is provided an information processing apparatus that makes it possible to apply a tactile stimulus in a more flexible manner in accordance with the position of a tactile-sense applying unit. The information processing apparatus includes: an acquiring unit that acquires the positional information on at least one of a plurality of tactile-sense applying units that apply a tactile stimulus by using a tactile control signal generated for each of the tactile-sense applying units; and a data processing unit that changes the tactile control signal by using the positional information.
