Foldable AOD Screen Selection Using Face and Eye Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outward-foldable electronic devices face challenges in determining which screen to display the always on display (AOD) interface when in different states, leading to suboptimal user experience due to incorrect screen selection.
Innovation Solution
The method involves detecting the folded state and user interaction to determine whether a human eye or face is present, activating the appropriate camera, and displaying the AOD interface on the screen facing upward or in response to user touch or after a preset time, ensuring the interface is displayed on the user-facing screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the AOD interface is displayed on a fixed screen regardless of device state, then the display control is simple, but the user experience deteriorates because the interface may not appear on the user-facing screen
Solution Approach 1:
The patent implements dynamic screen selection for AOD display based on device state. The system determines whether the device is folded or unfolded, and selects different screens (main screen or rear screen) accordingly. This dynamic adaptation ensures the AOD interface always appears on the user-facing screen, resolving the contradiction between simple control and good user experience.
2Measurement precision
If cameras are activated to detect user presence, then the accuracy of screen selection improves, but power consumption increases
Solution Approach 1:
The patent activates cameras only when needed for screen doze operations or when determining AOD display targets. By performing camera activation as a preliminary action only in specific scenarios rather than continuously, the system achieves accurate user presence detection while avoiding unnecessary power consumption during normal operation.
3Adaptability or versatility
If the AOD interface adapts to different device states (folded/unfolded), then the adaptability improves, but the device complexity increases due to multiple state detection requirements
Solution Approach 1:
The patent employs sensors and cameras that serve multiple functions: they detect both device state (folded/unfolded) and user presence (eye/face detection). This multi-functionality allows the system to achieve high adaptability for AOD display across different states without proportionally increasing device complexity, as the same hardware components handle multiple detection tasks.

AI summary
This application provides an always on display method and a related apparatus. In the method, when the electronic device is in a screen-doze state, it may be first determined whether the electronic device is in a folded state and then determined whether a condition for displaying an AOD interface is satisfied, such as recognizing a human face or a human eye, or the like, and may determine a screen displaying an AOD interface. In this way, the AOD interface can be better displayed based on a user requirement.
