Biological Feedback Detection for Distributed Tactile Stimulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tactile stimulation technologies in virtual reality systems are limited to stimulating only the region where the device is attached, failing to provide a wide-range tactile experience.
Innovation Solution
A system comprising first and second stimulating units that stimulate skin sensations in different body parts, with intensity measuring and ratio calculating units to enhance sensation intensity and distribution across the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If tactile stimulation devices are attached to specific body regions, then the stimulation intensity and precision in that region can be controlled, but the coverage area is limited to only the attachment region
Solution Approach 1:
The system segments the body into multiple body parts and uses multiple stimulating units distributed across different body regions. Each stimulating unit independently stimulates its local region, and the control unit coordinates them to achieve whole-body coverage without requiring a single large complex device
Solution Approach 2:
The control unit serves multiple functions: it controls multiple stimulating units, calculates stimulation intensity ratios, determines correspondence between body parts, and coordinates training modes. This multi-functionality allows comprehensive body coverage without proportionally increasing device complexity
2Area of stationary object
If multiple stimulating units are used to cover more body areas, then the coverage area increases, but the control complexity and measurement precision requirements increase
Solution Approach 1:
The system uses feedback from sensation intensity measurements to dynamically adjust stimulation parameters. The control unit receives measurement data from multiple stimulating units, calculates the correspondence ratio, and uses this feedback to optimize stimulation distribution, thereby maintaining measurement precision while expanding coverage
Solution Approach 2:
The system changes stimulation parameters (intensity, frequency, duration) based on the calculated correspondence ratio between body parts. By dynamically adjusting these parameters, the system maintains precise control over sensation intensity across multiple body regions without requiring equally precise measurement infrastructure everywhere
3Adaptability or versatility
If stimulation is applied to one body part, then the sensation is localized to that area, but the immersive experience and whole-body sensation are reduced
Solution Approach 1:
The system transitions from localized one-point stimulation to distributed multi-dimensional stimulation across the body. By stimulating multiple body parts simultaneously or sequentially and calculating correspondence ratios, it creates a distributed sensory experience that enhances immersion without losing localized sensation quality
Solution Approach 2:
The system merges stimulation from multiple body parts into a unified tactile experience. The control unit combines information from multiple stimulating units and coordinates their output to create an integrated whole-body sensation, thereby preserving sensory information while expanding tactile presentation versatility
