Lock Screen Augmented Reality Preview Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lock screen feature on electronic devices increases the time required to access applications, making it inconvenient for users to quickly access information, especially with the rise of augmented reality applications where timely information is needed.
Innovation Solution
The system allows for the presentation of applications on a locked device by using the power button to activate an augmented reality view, and orientation sensors to switch between views without unlocking the device, enabling quick access to information while maintaining low power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device requires unlocking to access applications, then device security is maintained, but access time increases
Solution Approach 1:
The patent segments the application access process into two modes: full access requiring unlock, and limited preview access available in locked state. The lock screen is divided into traditional widget area and augmented reality preview area, allowing users to access application previews without full authentication while maintaining security for actual data access.
Solution Approach 2:
The system performs preliminary rendering of augmented reality previews and widget content in the locked state, so that when the user unlocks the device, the applications are already loaded and ready for immediate interaction. This preliminary preparation eliminates the need to load applications from scratch after unlocking.
2Speed
If the device allows application access in locked state, then access speed increases, but power consumption increases
Solution Approach 1:
The patent implements partial action by allowing limited application previews and widget updates in the locked state without enabling full application functionality. Only essential rendering and sensor processing are activated, while complete application execution remains disabled until unlock. This selective activation provides quick previews while minimizing power consumption.
Solution Approach 2:
The system uses periodic updates for widget content and augmented reality previews in the locked state, rather than continuous full rendering. Sensors are activated periodically to update previews, and the display refreshes at lower intervals when locked, reducing overall power consumption while maintaining the appearance of responsiveness.
3Ease of operation
If augmented reality previews are enabled on lock screen, then application accessibility improves, but device complexity increases
Solution Approach 1:
The patent makes the existing lock screen and augmented reality framework multi-functional by enabling them to serve both traditional widget display purposes and new application preview purposes simultaneously. The same hardware sensors and display resources are utilized for dual functions without requiring separate dedicated systems.
Solution Approach 2:
The system introduces an intermediary layer that sits between the application data sources and the lock screen display. This intermediary handles the rendering and presentation of augmented reality previews, managing the complexity internally while presenting a simplified interface to users. The intermediary translates complex application data into preview formats suitable for locked state display.

AI summary
An approach is provided for increasing the functionality of an electronic device when the device is in a locked state. The approach involves determining one or more applications for presentation at a device. The approach also involves determining that the device is in a locked state. The approach further involves processing and/or facilitating a processing of the one or more applications to cause, at least in part, presentation of the one or more applications in a user interface of the device associated with the locked state.
