Mobile Viewing Angle Control Using Position and Gyro Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current viewing angle adjustment methods on mobile terminals require a separate screen sliding operation, necessitating suspension of ongoing tasks and increasing operational complexity.
Innovation Solution
Utilizing sensors, such as spatial location sensors or gyros, to detect position or angular changes of the terminal, allowing automatic adjustment of viewing angles based on these changes without manual screen sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screen sliding operation is used to adjust viewing angle, then viewing angle can be adjusted, but operation complexity increases and current task must be suspended
Solution Approach 1:
The patent replaces the mechanical touchscreen sliding operation with an acoustic signal-based viewing angle adjustment system. Users can adjust viewing angles by providing acoustic inputs (such as clapping or speaking), which eliminates the need to suspend current tasks and perform separate screen sliding operations, thereby reducing operation complexity while maintaining viewing angle adjustment capability
Solution Approach 2:
The system enables hands-free operation by detecting acoustic signals from the user's natural actions (clapping, speaking) to automatically adjust the viewing angle. This self-service mechanism allows users to adjust viewing angles without needing to manually operate the touchscreen, thus eliminating the need to suspend current tasks and reducing operational interruptions
2Ease of operation
If screen sliding operation is used to adjust viewing angle, then viewing angle can be adjusted, but time is lost due to task suspension
Solution Approach 1:
The acoustic signal-based adjustment system allows users to adjust viewing angles without interrupting their current tasks. By detecting acoustic inputs during task execution and automatically adjusting the viewing angle, the system maintains continuous task flow and eliminates the time loss associated with suspending and resuming operations
Solution Approach 2:
The system performs viewing angle adjustment automatically through acoustic signal detection, enabling users to maintain continuous engagement with their primary tasks while the system handles viewing angle adjustments in the background, thereby eliminating time loss due to task suspension and manual intervention
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the viewing angle adjustment process by enabling hands-free operation, reducing the complexity associated with traditional methods.
Implementation Method 1
a sensor in the terminal detects that the terminal changes from a first position to a second position
Implementation Method 2
The sensor may also be a gyro, which is used to detect angle or angular change (or orientation, or orientation change) of the terminal

AI summary
A method for viewing angle adjustment according to one embodiment may include: displaying a first image in a virtual scene at a first viewing angle when the terminal is at a first position; detecting a terminal position change from the first position to a second position; determining a viewing angle adjustment sensitivity based on one of: whether there is a press operation on a region of a touchscreen of the terminal; or whether a displaying mode of the virtual scene is a panorama mode; determining an angle variation reflecting viewing angle change based on: a position variation from the first position to the second position, and the viewing angle adjustment sensitivity; determining a second view angle based on the angle variation and the first viewing angle; and displaying a second image in the virtual scene at the second viewing angle when the terminal is located at the second position.
