Hand-Trajectory Gesture Recognition for Shooting Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require users to tap the screen to switch between shooting modes, which is inconvenient.
Innovation Solution
An electronic device recognizes user gestures, such as sliding or flipping motions, to switch between shooting modes by analyzing hand position changes in image frames, accurately distinguishing between waving and sliding gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture recognition is used to switch shooting modes, then ease of operation is improved, but gesture recognition accuracy deteriorates due to misrecognition between similar gestures
Solution Approach 1:
The gesture recognition process is segmented into multiple independent analysis dimensions: hand posture recognition, movement trajectory analysis, and gesture type classification. By dividing the recognition task into separate modules, each can be optimized independently to improve overall accuracy while maintaining ease of operation.
Solution Approach 2:
The system implements feedback mechanisms where recognition results are continuously refined based on trajectory data and posture information. The multi-dimensional analysis provides feedback loops that correct misrecognition in real-time, ensuring accurate gesture identification while keeping the interface simple for users.
2Adaptability or versatility
If multiple camera views are displayed simultaneously, then adaptability is improved, but device complexity increases
Solution Approach 1:
The electronic device utilizes its existing camera and display components to perform multiple functions: capturing images for gesture recognition, displaying preview windows for different shooting modes, and providing user feedback. This multi-functionality allows the device to adapt to various shooting scenarios without adding dedicated hardware complexity.
Solution Approach 2:
The system uses the device's own camera to capture the user's gestures for mode switching, eliminating the need for separate sensors or input devices. The display system serves dual purposes by showing both preview images and gesture recognition feedback, reducing overall device complexity while maintaining adaptability.

AI summary
A shooting method is provided. By implementing the shooting method provided in embodiments of this application, a terminal electronic device such as a smartphone or a smart television can determine to change a shooting mode based on a recognized user gesture. The electronic device can recognize a user's waving or sliding gesture more accurately based on the user's hand position change track in an image frame sequence and whether there are hand movements in two directions in the position changes. In this way, a misrecognition rate of the extremely similar waving and sliding gestures is reduced, and user experience is improved.
