Gesture Recognition Visual Feedback Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gesture recognition systems for control devices lack confirmation mechanisms to ensure that user gestures are accurately recognized, particularly when using camera-based image processing.
Innovation Solution
A control method and system that involves obtaining a taken image of an operator, displaying it on a display device, detecting operation gestures from the image, generating a second display image based on the detected gestures, and displaying this image on the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture recognition is performed using camera-based image processing, then the control device can operate without physical contacts, but the user cannot confirm whether the gesture is recognized accurately
Solution Approach 1:
The system displays the captured image of the user's gesture on the display device, providing visual feedback to confirm whether the gesture is recognized accurately. This feedback mechanism allows users to verify the recognition result and perform corrections if necessary, thereby resolving the contradiction between contactless operation and recognition reliability.
2Reliability
If the taken image is displayed to confirm gesture recognition, then the reliability of control is improved, but the device complexity increases
Solution Approach 1:
The display device serves multiple functions: it displays normal operating information and simultaneously displays the captured gesture image for verification. By making the display device multi-functional, the system avoids adding separate verification hardware, thus improving reliability without significantly increasing device complexity.

AI summary
A third controller of a control device executes obtaining a taken image obtained by imaging an operator, making a projector display a first display image including the taken image, detecting an operation gesture corresponding to processing to be executed by the control device from the taken image, generating a second display image based on the operation gesture, and making the projector display the second display image.
