Solution Overview

Problem

Current gesture recognition systems require users to enable a detecting time period before making motions, which is inconvenient as users must manually initiate each gesture detection process.

Innovation Solution

A generic gesture detecting method and device that automatically detects gestures by receiving sensing signals, generating images, and comparing them to stored images to determine similarity, allowing for continuous gesture recognition without the need for manual initiation.

1Ease of operation

If a detecting time period is used to detect gesture signals, then gesture detection can be performed, but users must manually enable the detecting time period before each gesture, which is inconvenient

Engineering Contradiction:

Improvegesture detection convenienceVSAvoiddetection system complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically detects gestures by continuously comparing current images with stored images without requiring user initiation. The detection algorithm autonomously identifies gesture patterns and triggers commands, making the system self-serving and eliminating manual enabling of detection periods.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs continuous image capture and comparison operations, maintaining constant gesture detection capability. By continuously comparing current images with stored reference images, the system ensures gesture detection is always active without interruption or manual reactivation.

Inventive Principle:

Principle #20Continuity of useful action

2Productivity

If continuous gesture detection is implemented without detecting time period, then user convenience is improved, but false detection from normal motions may increase

Engineering Contradiction:

Improvegesture detection speedVSAvoidgesture detection accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

Reference images representing valid gesture patterns are pre-stored in the system before actual gesture detection begins. These reference images serve as templates for comparison, enabling the system to distinguish genuine gestures from random motions by matching against predetermined patterns.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system compares current captured images with stored reference images and provides feedback through similarity assessment. This comparison mechanism filters out false detections by requiring match with predefined gesture patterns, ensuring reliable gesture recognition while maintaining continuous detection capability.

Inventive Principle:

Principle #23Feedback

AI summary

A generic gesture detecting method executed by a generic gesture detecting device includes steps of: receiving a current sensing signal from a sensing unit; generating a current image according to the current sensing signal; determining whether the current image is similar with a stored image stored in a memory unit; when the current image is similar with the stored image, detecting the current image and the stored image to be a gesture signal; when the current image is different from the stored image, storing the current image into the memory unit, and returning to the step of receiving a current sensing signal. Since the generic gesture detecting device can automatically detect the gesture signal, the user may not need to enable a detecting time period before implementing a command motion. Therefore, the user can make the command motion without enabling the detecting time period, and the convenience can be increased.
