Tactile Control Device Isolating Target Vibrations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tactile vibration technologies face challenges in ensuring users perceive desired tactile stimuli reliably, as output stimuli can be masked by other vibrations and may propagate to unintended locations, making it difficult to isolate and accentuate the desired sensation.
Innovation Solution
A control device and method that acquire information on tactile stimuli from both a primary and secondary source, allowing the control of the secondary source's output based on this information to enhance perception of desired tactile stimuli by suppressing noise vibrations and focusing on target vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tactile stimuli are output from a tactile stimulus generation source, then users can perceive tactile feedback, but other tactile stimuli and noise vibrations interfere with the clarity and accuracy of the desired tactile stimulus
Solution Approach 1:
The patent extracts and isolates the desired tactile stimulus from the composite vibration signal by identifying and separating it from other tactile stimuli and noise vibrations. The control device extracts information about the desired tactile stimulus and uses it to control the output, effectively taking out the useful signal from the noisy environment.
Solution Approach 2:
The control device acquires information about the tactile stimulus from the tactile stimulus generation source and uses this feedback information to control the output of the tactile stimulus. This closed-loop feedback mechanism allows the system to adjust and optimize the tactile stimulus output to overcome interference from other vibrations and noise.
2Reliability
If tactile stimuli propagate to multiple locations, then the stimulus can be felt across different areas, but the stimulus spreads to locations other than the desired presentation location, reducing precision
Solution Approach 1:
The patent applies local quality by controlling the tactile stimulus output at specific locations rather than uniformly across all areas. The control device manages the propagation characteristics to ensure the stimulus is concentrated at the desired presentation location while minimizing spread to other areas, creating localized tactile feedback with high spatial precision.
Data Source
AI summary
To provide a structure capable of causing a user to perceive a desired tactile stimulus more reliably. A control device including: an information acquisition unit configured to obtain first information regarding a tactile stimulus transferred from a first tactile stimulus generation source and second information regarding a tactile stimulus which a user is caused to perceive; and a control unit configured to control output of a tactile stimulus of a second tactile stimulus generation source different from the first tactile stimulus generation source on a basis of the first information and the second information. Further, a control method using a processor and a computer system program.
