Solution Overview
Problem
Conventional devices cannot reproduce user-desired vibration patterns associated with the movement of a vibration source, and users of tactual vibration clocks can only perceive which tactile unit is vibrating, lacking information about more complex vibrations.
Innovation Solution
A vibration data generation device and program that acquire information about a virtual vibration source and generate vibration data to control multiple vibrators, allowing for the reproduction of complex vibration patterns associated with the movement of a virtual vibration source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional devices use simple acceleration replacement to generate vibration, then the device structure remains simple, but the vibration pattern cannot reproduce user-desired complex vibrations associated with movement of a vibration source
Solution Approach 1:
The patent uses acceleration sensor data to copy and reconstruct the vibration pattern of a virtual vibration source. Instead of directly reproducing complex vibrations, the system captures acceleration information and processes it to generate vibration patterns that replicate the movement characteristics of the virtual source, achieving realistic tactile feedback without requiring complex mechanical structures
Solution Approach 2:
The patent replaces complex mechanical vibration generation systems with an electronic processing approach. Acceleration sensors detect movement, and the processor generates vibration patterns through electronic control of the vibrator, substituting mechanical complexity with electronic signal processing to achieve the same tactile reproduction effect
2Loss of information
If tactual vibration clocks provide only basic time information through vibration, then the device remains simple to operate, but users cannot obtain information about more complex vibrations
Solution Approach 1:
The patent segments the vibration information into multiple components by using multiple vibrators that can be independently controlled. Each vibrator can represent different aspects of the virtual vibration source's movement, allowing users to perceive complex vibration patterns as distinct tactile sensations while maintaining simple operation through automatic processing
Solution Approach 2:
The patent adds a temporal dimension to vibration information by continuously updating the vibration pattern based on the movement of the virtual vibration source over time. This transforms static vibration indication into dynamic tactile feedback that conveys movement trajectory and characteristics without requiring complex user interaction
