Orientation-Aware Electronic Device Shutter Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fixed shutter position on electronic devices can be inconvenient for users in certain scenarios, affecting the shooting experience.
Innovation Solution
The electronic device provides multiple shutters at different positions in the screen, allowing users to select the most convenient one based on the device's orientation relative to gravity, with the ability to move and adjust the position of the additional shutter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed shutter position is used on the camera screen, then the device structure is simple, but the ease of operation deteriorates when the device orientation changes
Solution Approach 1:
The shutter control is transformed from a fixed static position to a dynamic position that changes based on device orientation. The system continuously monitors the device's angle relative to gravity and automatically adjusts the shutter position on the screen to remain accessible regardless of how the user holds the device, making the control adaptive and dynamic rather than static
Solution Approach 2:
The shutter position parameter on the screen is changed based on the device orientation parameter. When the device orientation changes (detected via gravity sensor), the system automatically updates the shutter's position parameter to an optimal location, allowing the same control element to serve multiple positions without adding physical components
2Ease of operation
If the shutter position changes with device orientation, then the ease of operation improves, but the device complexity increases due to additional sensors and control logic
Solution Approach 1:
The gravity sensor, which is already present in the device for other purposes (such as screen rotation and orientation detection), is repurposed to also control shutter position. This multi-functional use of existing hardware avoids adding dedicated sensors, and the control logic integrates with the existing orientation management system rather than creating a separate complex subsystem
Solution Approach 2:
The system automatically detects device orientation changes and adjusts the shutter position without requiring user intervention. The control logic autonomously monitors orientation parameters and repositions the shutter control element, making the system self-adjusting and eliminating the need for manual reconfiguration or additional user-facing controls

AI summary
This application provides an audio output method and a terminal device. The method helps to reduce operation complexity for users, improve intelligence of the terminal device, and eventually improve user experience. The method includes: sending, by a second terminal device, an audio output request to a first terminal device, where a user may operate the first terminal device or an audio output device connected to the first terminal device; and triggering the second terminal device to obtain audio data corresponding to the audio output request. When the audio output device is a wireless audio output device, the second terminal device may establish a communication link with the wireless audio output device, and control the wireless audio output device to output first audio signals corresponding to the audio data. When the audio output device is a wired audio output device, the first terminal device may obtain audio data from the second terminal device, and control the audio output device connected to the first terminal device to output first audio signals corresponding to the audio data.
