Tilt-Angle Control for Single-Handed Electronic Device Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices, such as smartphones and tablets, require both hands to operate, especially when searching and playing image files, which can be inconvenient in situations like crowded public transportation.
Innovation Solution
Incorporating a gravity sensor to detect tilt angles and a control unit that performs operations based on these angles, allowing single-handed control of electronic devices for user interface and audio/video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch interface operation is used, then user can interact with electronic device, but both hands are required for operation which reduces convenience in certain circumstances
Solution Approach 1:
The patent replaces the mechanical touch interface operation system with a gravity sensor-based detection system. Instead of requiring manual touch operations on the screen, the device detects tilt angles through gravity sensors and automatically performs corresponding operations, substituting mechanical hand operations with physical orientation detection
Solution Approach 2:
The device performs operations automatically based on detected tilt angles without requiring continuous user input. Once the device detects a specific tilt angle, it autonomously executes the corresponding operation (such as switching between images or adjusting playback), making the device self-serve the user's intent without requiring both hands for continuous manipulation
2Ease of operation
If both hands are required for operation, then precise control can be achieved, but operation becomes inconvenient in crowded environments
Solution Approach 1:
The patent changes the control parameter from touch position coordinates to tilt angle measurements. By detecting the angle at which the device is tilted relative to the horizontal plane, the system provides precise control through orientation parameters rather than manual positioning, maintaining control accuracy while enabling single-handed operation
