Wearable Hand Controller With Tactile Feedback for Remote Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation systems struggle to convey complex contents and expressions that are difficult to communicate through sound and video, such as tactile sensations and thermal feelings, lacking the realism of face-to-face interactions.
Innovation Solution
A communication system comprising a controller installed on a user's hand, an operation target, and a relay apparatus, which includes detection and stimulus providing sections to transmit and receive motion and stimulus information, allowing bidirectional communication of tactile and thermal sensations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple automation control system is used for remote operation, then the system structure is simplified and ease of operation is improved, but the ability to convey complex contents and expressions (such as tactile sensations and thermal feelings) deteriorates
Solution Approach 1:
The patent implements bidirectional feedback loops: the operation target's detection section senses external stimuli (tactile, thermal) and feeds this information back to the controller, which then provides corresponding stimuli to the user's fingers. This feedback mechanism enables the user to perceive remote environmental characteristics directly through tactile sensation, resolving the contradiction by maintaining simple operation while preserving rich sensory information
Solution Approach 2:
The controller acts as an intermediary device worn on the user's hand, mediating between the remote operation target and the user's sensory system. It receives action information from the detection section, translates it into appropriate stimuli, and delivers them to the fingers, thereby enabling complex sensory communication without complicating the overall system structure
2Ease of manufacture
If traditional sound and video communication is used for remote interaction, then the communication system is simple and ease of manufacture is improved, but the realism and sensory richness of face-to-face communication deteriorates
Solution Approach 1:
The patent replaces traditional auditory and visual communication channels with a tactile-based mechanical sensing and feedback system. By substituting sound and video with direct tactile stimuli transmitted through the controller to the user's fingers, the system achieves face-to-face realism while maintaining manufacturing simplicity, as the core components are standard sensors and actuators
