Control Device Synchronizing Tactile and Auditory Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feedback mechanisms that utilize sense stimulations for user operations often fail to ensure reliable perception and comfort, leading to suboptimal operability.
Innovation Solution
A control device and method that synchronizes tactile and auditory presentations by controlling waveform features to ensure both are perceivable and comfortable for the user, using a combination of input, detection, and output components to specify appropriate ranges for displacement rise time and sound sharpness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If feedback stimulation intensity is increased to improve user perception, then perceptibility is improved, but user comfort deteriorates
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the waveform feature amounts (such as vibration intensity, frequency, and sound pressure levels) based on the operational context and user state. The control section modifies these parameters in real-time to maintain feedback within an appropriate range that ensures perceptibility while preventing discomfort, rather than using fixed high-intensity stimulation.
Solution Approach 2:
The system implements dynamics by making the feedback characteristics adaptable and changeable according to different operating conditions. The control section continuously monitors and adjusts the tactile and auditory feedback parameters during operation, allowing the feedback system to transition between different intensity levels and patterns to optimize both perception and comfort based on current usage context.
2Object-affected harmful factors
If both tactile and auditory presentations are controlled to fall within appropriate ranges, then user comfort is improved, but feedback intensity may be reduced
Solution Approach 1:
The patent merges multiple feedback modalities (tactile vibration and auditory sound) into a unified feedback system. By combining these different sensory channels, the system can provide comprehensive feedback that remains within comfortable intensity ranges for each individual modality while maintaining overall feedback effectiveness through the synergistic effect of multiple presentation types.
Solution Approach 2:
The control section is designed to universally manage both tactile and auditory feedback through a single control mechanism. This multi-functional approach allows the system to adjust both feedback types within appropriate ranges simultaneously, ensuring that neither modality causes discomfort while maintaining effective communication with the user through diverse feedback channels.

AI summary
There is provided a control device that includes: a control section configured to control tactile presentation and auditory presentation when it is decided that an input section has been operated, the tactile presentation presenting a stimulation via a sense of touch, the auditory presentation presenting a stimulation via a sense of hearing, and the input section having a contact area that an object contacts, and in which the control section controls a feature amount of a waveform related to the tactile presentation and a feature amount of a waveform related to the auditory presentation such that at least one of the tactile presentation and the auditory presentation falls within an appropriate range that is a range where at least one of the tactile presentation and the auditory presentation is perceivable for a user of the input section and is not uncomfortable for the user.
