Tactile Feedback Control Switching for Content-Adaptive Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices struggle to provide a tactile stimulus tailored to the specific content being consumed, such as video, sound, or computer games, lacking flexibility and efficiency in generating appropriate tactile feedback.
Innovation Solution
A control device that includes a reproduction unit and a switching control unit to manage sound and tactile data based on content information, system configuration, and communication method, allowing for dynamic switching between internal generation and content-provided tactile data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tactile data is always generated internally from sound data, then tactile feedback can be provided for any content, but power consumption increases and processing time is wasted when tactile data is already available in content data
Solution Approach 1:
The system dynamically switches between two tactile data sources based on real-time conditions: using pre-provided tactile data from content when available, and generating tactile data from sound data when needed. This dynamic adaptation optimizes power consumption while maintaining tactile feedback availability for all content types.
Solution Approach 2:
The system checks whether tactile data is already provided by the content source itself before resorting to internal generation. This self-service approach prioritizes using externally provided resources, reducing the need for power-consuming internal processing when tactile feedback is already available.
2Adaptability or versatility
If tactile data is always generated internally from sound data, then tactile feedback can be provided for any content, but processing time is wasted when tactile data is already available in content data
Solution Approach 1:
The system performs preliminary checking to determine whether tactile data is already provided with the content before initiating internal generation. This advance verification prevents unnecessary processing time consumption by identifying cases where tactile feedback data is already available, eliminating redundant computational steps.
3Device complexity
If a single tactile data source is used, then system complexity is reduced, but adaptability to different content types and device configurations is limited
Solution Approach 1:
The system implements a universal tactile feedback mechanism that can handle multiple content types and device configurations through a single unified architecture. This architecture accepts tactile data from both pre-provided content and internal generation, making the system adaptable to various scenarios without requiring separate specialized systems for each content type.
Solution Approach 2:
The control device acts as an intermediary between different tactile data sources (pre-provided tactile data and internally generated tactile data) and the tactile output device. This mediator selectively routes appropriate tactile data based on content type and device configuration, achieving high adaptability while maintaining a relatively simple system structure through centralized control logic.

AI summary
A control device includes a reproduction unit that causes stereo speakers of an aural-tactile presentation device to output sound on the basis of sound data and causes tactile presentation units provided corresponding to the respective stereo speakers in the aural-tactile presentation device to provide a tactile stimulus on the basis of tactile data, and a switching control unit that switches, on the basis of content information of content data including at least the sound data, the tactile data to be input to the tactile presentation units to either the tactile data generated by a tactile data generation unit on the basis of the sound data or the tactile data included in the content data.
