Tactile Skill Transfer via Intermediary Stimulus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transferring physical skills, such as those in traditional crafts and manufacturing, face challenges in efficiently conveying tactile sensations from skilled workers to learners, as simultaneous somesthetic information from both parties interferes, hindering effective learning and work performance.
Innovation Solution
A skill acquisition assistance system that includes a sensor section to acquire tactile data from a skilled worker's body part during work and a stimulus transmission section to generate and transmit stimuli to a different body part of the learner, allowing for the recognition and comparison of tactile sensations without interference, enabling immediate correction of actions without affecting workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a tactile presentation device is worn on the fingertip to transmit somesthetic information, then the learner can receive tactile guidance from the skilled person, but the learner's own tactile sensation and the presentation information interfere with each other, making it difficult to understand and compare sensations
Solution Approach 1:
The patent introduces an intermediary stimulus transmission section that transmits tactile information to a body part other than the fingertip (such as the wrist or arm). This mediator allows the skilled person's tactile information to be conveyed to the learner without directly interfering with the learner's own fingertip tactile sensations, enabling clear comparison and understanding of tactile differences.
2Loss of information
If tactile presentation is provided at the working body part, then skill transfer can occur, but the presentation hinders the work and may not provide sufficient learning effect
Solution Approach 1:
By using a stimulus transmission section mounted on a body part other than the working fingertip, the patent creates an intermediary transmission path that does not hinder the work itself. The learner can maintain normal work performance while receiving tactile information through the intermediary location, thus avoiding the conflict between learning and working.
3Loss of information
If multiple tactile information sources are given simultaneously to the same body part, then comprehensive feedback is provided, but the information interferes with each other and prevents direct comparison
Solution Approach 1:
The patent segments the tactile information channels by directing different tactile information to different body parts. The learner's own tactile sensations from the fingertip remain separate from the transmitted tactile information received at the wrist or arm, allowing clear discrimination and comparison between self-generated and transmitted tactile signals.
Data Source
AI summary
A skill acquisition assistance method includes a first stimulus generating step of acquiring first and second tactile data indicating tactile senses corresponding to a first body part based on an action of the first body part during work time when first and second workers perform the same work and generating a first stimulus based on the first tactile data by a stimulus transmission section mounted on a second body part different from the first body part of the first worker and a second stimulus generating step of switching a stimulus generated by the stimulus transmission section to a second stimulus based on the second tactile data in conjunction with the action of the first body part of the first worker.
