Terminal Camera Control via Holding Status Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices require complex user operations to start the camera application, leading to poor human-machine interaction performance and negatively impacting user experience, especially when users need to quickly capture fleeting images.
Innovation Solution
A method and terminal configuration that detects user intent to take photos by monitoring sensor data, such as changes in device orientation and motion, to automatically display camera controls on the screen, allowing users to initiate the camera application directly from any interface without needing to navigate to the home screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal requires users to navigate through multiple interfaces (exit current application -> return to home screen -> tap camera icon) to start the camera application, then the system operation flow is standardized and reliable, but the user operation complexity increases and human-machine interaction performance deteriorates
Solution Approach 1:
The system performs preliminary detection of user holding status changes before the user actually intends to take a photo. When sensors detect that the user has picked up the terminal and changed the holding status, the system proactively displays the photographing control on the current interface, preparing the camera function in advance. This eliminates the need for users to navigate through multiple interfaces, as the camera control is already visible and accessible on the current screen.
2Speed
If the terminal automatically displays photographing control when detecting holding status change, then user operation time is reduced and responsiveness is improved, but the risk of false triggering increases
Solution Approach 1:
The system dynamically adjusts the photographing control display based on real-time sensor data. The photographing control is displayed in a floating manner that can move according to user interactions, and the system continuously monitors holding status to confirm the user's intent. This dynamic approach allows the system to respond quickly to genuine photo-taking intentions while maintaining the ability to adapt and cancel the display if the holding status changes again, thereby reducing false triggering.
3Adaptability or versatility
If the photographing control is displayed on the first interface (non-viewfinder interface), then users can access camera functionality from any screen state, but the user cannot see the captured image until switching to the viewfinder interface
Solution Approach 1:
The system uses the first interface as an intermediary layer between the user's photo-taking intent and the actual viewfinder interface. When the user triggers the photographing control on the first interface, the system captures the image and then transitions to the viewfinder interface to display the captured image. This intermediary approach allows the system to maintain adaptability by accepting photo commands from any screen state while ensuring visual feedback is provided through the subsequent viewfinder interface, thus resolving the information loss issue.

AI summary
A terminal includes a camera and a sensor, where the sensor is configured to detect a status of holding the terminal by a user; the terminal displays a first interface, and displays a first photographing control on the first interface in response to detecting that a current status of holding the terminal by the user undergoes a change satisfying a preset condition, where the first interface is not a viewfinder interface of the terminal; and the terminal displays a second interface in response to an operation of the user on the first photographing control, where the second interface is a viewfinder interface of the terminal.
