Vibration Control Apparatus for Dynamic Pseudo Force Sensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration devices struggle to provide a pseudo force sensation that matches the content being viewed, as it is often difficult for content suppliers to predefine this sensation, leading to a lack of enhanced realistic experience for users.
Innovation Solution
A vibration control apparatus and method that acquires content information from video and audio and uses this data to control a vibration mechanism, generating a pseudo force sensation tailored to the content being presented, allowing for dynamic and context-specific tactile feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vibration device uses conventional vibration waveforms, then the device can provide basic tactile feedback, but it cannot present a pseudo force sensation that matches the content being viewed
Solution Approach 1:
The vibration control apparatus dynamically adjusts vibration parameters based on content information in real-time. The control section modifies vibration characteristics (amplitude, frequency, waveform) according to the type of content being viewed, such as switching between horizontal/vertical vibrations for different content types, thereby achieving adaptability without requiring a completely static complex system
Solution Approach 2:
The system incorporates content information acquisition that continuously monitors what content is being viewed and uses this information to adjust vibration output. This feedback loop allows the vibration device to adapt to different content dynamically, resolving the contradiction between adaptability and complexity by using intelligent control rather than multiple fixed vibration mechanisms
2Adaptability or versatility
If content suppliers predefine pseudo force sensation for all content, then matching tactile feedback can be provided, but it becomes difficult to cover all possible content types
Solution Approach 1:
The vibration control apparatus performs self-service by automatically analyzing content information and determining appropriate vibration patterns without requiring external predefined instructions for every content type. The control section independently decides which vibration mode to use based on content classification, eliminating the need for content suppliers to predefine sensations for all possible content
Solution Approach 2:
The system achieves universality by designing a vibration control apparatus that can handle multiple content types through a unified control mechanism. Rather than requiring separate predefined sensation libraries for different content types, a single adaptive system processes various content (videos, images, etc.) and generates appropriate vibrations, reducing overall system complexity
3Reliability
If the vibration mechanism is controlled to match every specific content type, then realistic sensation is enhanced, but the control system becomes more complex
Solution Approach 1:
The system segments content types into distinct categories (e.g., video content, image content, different orientation types) and assigns specific vibration patterns to each category. This segmentation approach maintains reliability by providing appropriate tactile feedback for each content type while managing complexity through classification rather than handling every possible content variation individually
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the presentation of a pseudo force sensation that enhances the user's experience by synchronizing tactile feedback with the content, providing a more realistic and engaging interaction, even when the sensation is not predefined.
Implementation Method 1
a vibration mechanism 21 and a control section 11. The reception section 23 receives a control command that specifies generation of a vibration causing a user to feel a pseudo force sensation defined based on content information about content while the content is being presented
Data Source
AI summary
