Hand Gesture Input via Finger Touch Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input methods require users to be near devices and master complex interaction skills, making them inconvenient for information input.
Innovation Solution
A method and apparatus that obtain a hand image to determine the state of fingers and touch areas, allowing users to input information by touching predefined areas on their hands, using preset correspondence relationships to associate finger positions with input information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional input devices (keyboard, mouse, touch screen) are used, then information input can be achieved, but the user must be near the device and master complex interaction skills
Solution Approach 1:
The patent replaces traditional mechanical input devices (keyboard, mouse, touch screen) with an optical recognition system that captures hand images via camera and uses image processing to recognize finger gestures. This substitution eliminates the need for physical contact with complex input devices while maintaining information input capability, directly resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The patent creates a visual copy (image) of the user's hand gesture through camera capture and image processing. Instead of requiring direct interaction with complex input devices, the system recognizes the copied visual representation of hand posture to determine input information. This copying approach simplifies user interaction while preserving the full range of input possibilities
2Adaptability or versatility
If the hand is divided into multiple touch areas, then more input information can be recognized, but the system complexity increases
Solution Approach 1:
The patent segments the hand into multiple predefined touch areas (such as finger tips, finger sides, palm areas) with specific functions assigned to each region. This segmentation enables rich input information recognition by detecting which areas are touched, while the predefined nature of these segments keeps the system complexity manageable through established correspondence relationships between areas and input meanings
3Ease of operation
If finger gesture recognition is used for input, then external devices are not needed, but the system must process and analyze hand images
Solution Approach 1:
The patent replaces the need for external input devices with an optical detection system that processes hand images. The camera-based image capture and automated processing algorithms eliminate the need for physical input devices, making the system more convenient while the automated image analysis reduces the perceived complexity for the user

AI summary
Aspects of the present invention are directed to a method for inputting information, including: obtaining a hand image; determining one or more first fingers in an open state in the hand image, and a target touch area touched by a second finger, the target touch area being one of predefined touch areas pre-divided in the one or more first fingers, in a palm, or in the one or more first fingers and the palm; determining target information to be input according to the one or more first fingers in the open state and the target touch area touched by the second finger.
