Handheld Controller Audio-Tactile Switching During Voice Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-functional controller apparatuses often experience involuntary operations when controlling multiple devices in a combined manner without considering the characteristics of each device, leading to unintended actions.
Innovation Solution
A controller apparatus equipped with a microphone, tactile sensation presentation device, and speaker, where sound emission from the speaker is reduced during microphone input, and the tactile sensation device controls tactile feedback, allowing coordinated control of multiple devices while preventing involuntary operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are controlled in a combined manner without considering individual device characteristics, then device functionality is integrated, but involuntary operations occur
Solution Approach 1:
The control system is segmented into device-specific control modules, where each device (microphone, speaker, tactile sensation device) has its own dedicated control logic. This segmentation ensures that each device operates according to its characteristics while being part of an integrated system, preventing involuntary operations caused by improper combined control.
Solution Approach 2:
The controller dynamically adjusts the operation state of each device based on real-time conditions. When the microphone is receiving sound input, the system dynamically reduces or stops speaker emission and activates tactile sensation control, adapting the system behavior to the current operational context to avoid conflicts and involuntary operations.
2Measurement precision
If sound emission from the speaker is reduced during microphone input, then input sound quality is improved, but speaker functionality is limited
Solution Approach 1:
The speaker and microphone operate in periodic alternating modes. During periods when microphone input is active, speaker emission is reduced or stopped. During periods when microphone input is inactive, speaker emission is restored. This periodic switching ensures high-quality sound input when needed while maintaining speaker functionality for other purposes.
Solution Approach 2:
The speaker output level is dynamically adjusted based on the operational state of the microphone. When the microphone is actively receiving sound input, the speaker emission is dynamically reduced or stopped to prevent feedback and improve input quality. When the microphone is not in use, the speaker returns to normal operation, maintaining full system versatility.
3Adaptability or versatility
If the tactile sensation device performs control during microphone input, then device coordination is achieved, but tactile feedback frequency is reduced
Solution Approach 1:
The tactile sensation device operates periodically in coordination with the microphone input state. During periods when the microphone is actively receiving sound, the tactile device performs control functions and provides tactile feedback. During periods when the microphone is not in use, the tactile device can be deactivated or operate in a different mode, ensuring proper device coordination while maintaining tactile feedback availability when needed.

AI summary
There are provided a controller apparatus and a control method thereof. The controller apparatus is held by a hand of a user and includes a microphone, a tactile sensation presentation device that presents a tactile sensation to the hand of the user, and a speaker. In addition, during a period in which the user inputs sound from the microphone, the controller apparatus reduces emission of sound of the speaker and causes the tactile sensation presentation device to perform control of tactile sensation presentation.
