Gesture Coaching System for Motion Recognition Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in learning and performing gestures required for controlling applications, such as games, due to unfamiliarity with the mapping of physical motions to application actions, leading to barriers in interaction and potential frustration.
Innovation Solution
The system provides gesture coaching by analyzing user data and output from gesture filters to determine when assistance is needed, offering visual assistance to teach proper gestures, using a display device to demonstrate correct motions and provide training modes, allowing users to learn and improve their gestures effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture controls are used for application manipulation, then ease of operation is improved, but difficulty of detecting and measuring worsens due to unfamiliarity with gesture mappings
Solution Approach 1:
The system provides real-time feedback to users by displaying an avatar that mirrors their physical gestures and offers coaching guidance when gestures are not recognized. This feedback loop helps users understand the mapping between physical motions and application actions, reducing the difficulty of detecting and measuring gestures while maintaining ease of operation.
Solution Approach 2:
The patent introduces an intermediary coaching system that mediates between the user's physical gestures and the application's gesture recognition. The coaching interface acts as a bridge, providing real-time guidance and visual feedback to help users bridge the gap between their physical actions and the expected gesture mappings.
2Measurement precision
If gesture recognition threshold is set high for accuracy, then measurement precision is improved, but ease of operation worsens due to stricter gesture requirements
Solution Approach 1:
The system provides feedback to users when gestures fail to meet the recognition threshold, offering coaching guidance on how to adjust their gestures. This allows the system to maintain high measurement precision for accurate gesture recognition while helping users adapt their gestures to meet the threshold requirements, thereby preserving ease of operation.
Solution Approach 2:
The coaching system provides preliminary guidance before gesture execution by indicating when assistance is appropriate and providing training information. This preliminary action helps users prepare for successful gesture execution, reducing the impact of strict thresholds on ease of operation.
3Ease of operation
If real-time gesture coaching is provided, then ease of operation is improved, but device complexity increases due to additional analysis and feedback mechanisms
Solution Approach 1:
The coaching system is segmented into modular components including gesture filtering, confidence level assessment, and visual feedback generation. Each component operates independently and can be activated based on user needs, reducing the overall complexity burden while maintaining ease of operation through real-time coaching.
Solution Approach 2:
The system dynamically adjusts the level of coaching provided based on real-time analysis of user performance and gesture confidence levels. The coaching intensity and type of feedback change dynamically based on the situation, allowing the system to manage complexity by only activating full coaching modes when needed while maintaining operational ease.
Data Source
AI summary
A capture device may capture a user's motion and a display device may display a model that maps to the user's motion, including gestures that are applicable for control. A user may be unfamiliar with a system that maps the user's motions or not know what gestures are applicable for an executing application. A user may not understand or know how to perform gestures that are applicable for the executing application. User motion data and/or outputs of filters corresponding to gestures may be analyzed to determine those cases where assistance to the user on performing the gesture is appropriate.
