Shaking Gesture Input for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals, especially touch screens, face challenges in convenient input instruction triggering due to small key sizes and the need for precise key selection, leading to potential input failures and inconvenience, especially in environments where visual access is limited.
Innovation Solution
A method where a mobile terminal detects shaking operations using an accelerometer to trigger preset input instructions, such as screen unlocking or data sending, without requiring users to physically locate and press keys, and generates user information requests to match users based on interest information stored on a server, facilitating friend-making by detecting shaking amplitudes and frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple keys are configured in the mobile terminal, then more input instructions can be triggered, but the keys become smaller and users easily press wrong keys causing input failure
Solution Approach 1:
The patent replaces the mechanical key pressing system with a shaking gesture recognition system. The accelerometer detects shaking motions and triggers corresponding input instructions without requiring physical key pressing, thereby solving the contradiction between having multiple input instructions and maintaining pressing accuracy
Solution Approach 2:
The patent introduces shaking gestures as an intermediary between the user and input instructions. Instead of directly pressing keys, users perform shaking gestures that are detected by the accelerometer and translated into input instructions, providing a more accurate and convenient input method
2Ease of operation
If a virtual key is used on touch screen, then input instructions can be triggered, but the user needs to first position the virtual key with naked eyes which reduces convenience
Solution Approach 1:
The patent replaces the visual positioning and pressing mechanism with a shaking gesture recognition system. The accelerometer detects shaking motions and automatically triggers the corresponding input instructions without requiring the user to visually locate and press virtual keys, thereby eliminating the time loss associated with key positioning
3Measurement precision
If keyword input is required for user matching, then precise user information can be obtained, but the operation complexity increases and convenience decreases
Solution Approach 1:
The patent replaces the manual keyword input system with an automatic shaking gesture recognition system. The accelerometer detects shaking gestures and automatically retrieves user information based on the detected gesture patterns, eliminating the need for manual keyword input while maintaining user information accuracy
Solution Approach 2:
The system performs user information retrieval automatically based on detected shaking gestures. The mobile terminal itself service the user by interpreting gestures and fetching user information without requiring manual keyword input, thereby simplifying operations while maintaining precision
