Mobile Terminal Posture Recognition for Automatic Selfie Camera Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for taking selfies on smartphones require complex operations, such as manually triggering the selfie camera, which can be inconvenient and prone to errors due to mismatched user postures.
Innovation Solution
A method where a mobile terminal automatically starts the camera when it detects a preset posture feature, potentially combined with user touch operations, to simplify and secure the selfie-taking process, allowing for real-time photography based on user habits and preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user manually triggers the selfie camera through virtual or physical keys, then the selfie camera can be activated, but the operation process becomes complex and inconvenient
Solution Approach 1:
The system pre-sets posture features that indicate the user intends to take a selfie. When the terminal detects that the user's posture matches these pre-set features, it automatically activates the selfie camera without requiring manual key triggering. This preliminary configuration of posture recognition rules enables automatic camera activation based on detected user intent, simplifying the operation process while maintaining reliable camera activation.
2Ease of operation
If the camera is automatically activated based on posture detection, then the operation process is simplified, but the risk of misoperation increases
Solution Approach 1:
The system requires that multiple posture features be simultaneously satisfied before triggering automatic camera activation. Instead of relying on a single posture indicator, the system uses a combination of posture features (such as holding orientation, screen viewing angle, and device position) to confirm user intent. This partial action approach ensures that the camera is activated only when sufficient evidence of selfie-taking intent is present, reducing misoperation while keeping the interface simple.
3Reliability
If multiple verification conditions are added to prevent misoperation, then security is improved, but the operation process becomes more complex
Solution Approach 1:
The system merges multiple verification conditions into a unified posture recognition framework. Instead of treating each verification condition (posture detection, touch operation detection, camera state checking) as separate steps that increase complexity, the system integrates them into a single coordinated process. The posture feature detection, touch operation detection, and camera activation control are merged into one automated workflow, maintaining high security while preserving operational simplicity.

AI summary
The present invention relates to photographing technologies of terminals, and provides a photographing method and a terminal, so as to resolve an existing problem of complex operations when a user photographs. The method is applied to a mobile terminal equipped with at least one camera, and includes: determining, by the mobile terminal, whether the mobile terminal meets a preset condition, where the preset condition may include matching of a posture feature of the mobile terminal with a standard posture feature that is used to represent a posture feature of the mobile terminal when a user uses a first camera to photograph; and if the mobile terminal determines that the mobile terminal meets the preset condition, starting the first camera to photograph.
