Camera Gesture Recognition Feedback to Prevent False Triggers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices often misrecognize user gestures intended for function execution, leading to unintended function activation.
Innovation Solution
An electronic device with a camera module and display that detects a gesture in a first state, displaying recognition progress until a variance in movement is less than a reference variance for a specified time, thereby preventing misrecognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device executes a function when a gesture is completed, then the function can be executed conveniently, but the device may misrecognize unintended gestures as intended gestures
Solution Approach 1:
The system performs preliminary actions by detecting gesture start conditions and entering a recognition state before the gesture is completed. This preliminary detection phase allows the system to prepare for potential gesture recognition without immediately executing functions, thereby reducing misrecognition while maintaining ease of operation.
Solution Approach 2:
The system implements feedback by providing visual indicators (e.g., displaying that gesture recognition is in progress) during the gesture detection and recognition process. This feedback mechanism allows users to understand the system's current state, confirm whether their intended gesture is being recognized, and correct unintended gestures before execution, thus improving reliability without compromising convenience.
2Productivity
If the device recognizes gesture completion to execute functions, then function execution is enabled, but unintended functions may be executed due to misrecognition
Solution Approach 1:
The system performs preliminary detection of gesture start conditions and enters a recognition state before final execution. This preliminary phase separates detection from execution, allowing the system to verify gesture validity before committing to function execution, thereby maintaining productivity while improving reliability.
Solution Approach 2:
Visual feedback during the recognition process enables users to verify whether their gesture is being correctly interpreted before function execution. This feedback loop ensures that only intended gestures trigger functions, preventing unintended executions while maintaining efficient operation.
3Ease of operation
If the device uses gesture recognition technology, then user convenience is improved, but misrecognition of gestures occurs
Solution Approach 1:
The system performs preliminary detection of gesture start conditions before full recognition and execution. This preliminary phase allows the system to identify potential gestures and enter a monitoring state, providing an opportunity to distinguish between intended and unintended gestures, thereby improving detection precision while maintaining ease of operation.
Solution Approach 2:
The system provides visual feedback during the gesture recognition process, allowing users to understand whether their gesture is being detected as intended. This feedback mechanism enables users to correct unintended gestures before execution, improving measurement precision without compromising user convenience.

AI summary
An electronic device according to various embodiments comprises: at least one camera; a display; and a processor; and memory storing instructions that, when executed by the processor, cause the electronic device to: in a first state in which a gesture for executing a function is recognizable, detect, using the camera module, a movement of an object to be recognized for a gesture; and based on identifying that a variation of the detected movement is less than a reference variation during a specified time period, display, on the display, that a recognition of a gesture is in progress, until before the recognition of the gesture is terminated.
