Information Processing Device Tactile Stimulus Sound Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively prevent users from perceiving sound emitted by tactile stimuli, leading to discomfort during experiences like movies or concerts, where the tactile stimulus sound is perceived as noise, disrupting the auditory experience.
Innovation Solution
An information processing device generates tactile data based on user perception characteristics of both acoustic and tactile stimuli to adjust the signal-to-noise ratio, ensuring the tactile stimulus sound is not perceived by adjusting the sound pressure levels and frequency bands to be lower than the primary sound in the audible range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tactile stimulus is presented to improve presence and user experience, then user immersion is enhanced, but sound emitted by tactile stimulus is perceived by user causing discomfort
Solution Approach 1:
The patent applies parameter changes by adjusting the frequency band and sound pressure level of tactile stimulus signals. The generation section modifies these parameters to ensure the second sound falls below the user's perception threshold, thereby maintaining immersive experience while preventing noise discomfort.
Solution Approach 2:
The patent implements feedback mechanisms by acquiring information about user perception characteristics regarding both first sound (acoustic presentation) and second sound (tactile stimulus). This feedback is used by the generation section to dynamically adjust tactile stimulus parameters, preventing perceived noise while maintaining effectiveness.
2Illumination intensity
If acoustic presentation is provided to enhance auditory experience, then sound quality is improved, but tactile stimulus sound becomes noticeable as interference
Solution Approach 1:
The patent changes parameters of the tactile stimulus by adjusting its frequency band and sound pressure level based on the relationship between first sound and second sound. This ensures that tactile noise does not interfere with the acoustic presentation while maintaining the desired tactile effect.
Solution Approach 2:
The patent performs preliminary action by acquiring perception characteristic information and generating appropriate tactile stimulus data before presenting the tactile stimulus. The generation section pre-adjusts the parameters to prevent noticeable interference with the acoustic presentation.

AI summary
[Object] To prevent appropriately that a user perceives sound emitted by a tactile stimulus (second sound). [Solving Means] To provide an information processing device including a generation section that generates, on the basis of information regarding a first perception characteristic of a user with respect to a first sound emitted from an acoustic presentation section and information regarding a second perception characteristic of the user with respect to a second sound emitted by a tactile stimulus presented from a tactile data presentation section, tactile data to be used for presentation of the tactile stimulus of emitting the second sound that is not perceived by the user.
